Hepzato Kit
FDA Label NDC 75833-601

• Severe peri-procedural complications including hemorrhage, hepatocellular injury, and thromboembolic events may occur via hepatic intra-arterial administration of HEPZATO. Assess patients for these adverse reactions during and for at least 72 hours following administration of HEPZATO [see Warnings and Precautions (5.1)].
• HEPZATO is available only through a restricted program under a Risk Evaluation and Mitigation Strategy called the HEPZATO KIT REMS [see Warnings and Precautions (5.2)].
• Myelosuppression with resulting severe infection, bleeding, or symptomatic anemia may occur with HEPZATO. Monitor hematologic laboratory parameters and delay additional cycles of HEPZATO therapy until blood counts have improved. [see Warnings and Precautions (5.1)]

HEPZATO for injection, as a component of the HEPZATO KIT, is indicated as a liver-directed treatment for adult patients with uveal melanoma with unresectable hepatic metastases affecting less than 50% of the liver and no extrahepatic disease or extrahepatic disease limited to the bone, lymph nodes, subcutaneous tissues, or lung that is amenable to resection or radiation.

HEPZATO is a component of the HEPZATO KIT Hepatic Delivery System [HDS]. Refer to the HEPZATO KIT Hepatic Delivery System Instructions for Use (IFU) for additional instructions including pre-infusion evaluation, hydration, premedication, anticoagulation, and supportive care.

Caution: The double balloon catheter component of the HDS contains natural rubber latex which may cause allergic reactions [see Contraindications (4)].

• Healthcare providers must complete the required HEPZATO KIT REMS training prior to administration of the HEPZATO KIT [see Warnings and Precautions (5.2)].
• Discontinue oral anticoagulation and drugs affecting platelet function prior to the procedure [see Warnings and Precautions (5.1)].
• Discontinue ACE-inhibitors, calcium channel blockers, or alpha-1-adrenergic blockers prior to the procedure [see Warnings and Precautions (5.1)].
• Conduct baseline hematologic testing. Administer intra-hepatic HEPZATO with the HEPZATO KIT only to patients with the following [see Warnings and Precautions (5.3)].
  • Hemoglobin ≥ 10 g/dL
  • Platelets ≥ 100,000/microliter
  • Neutrophils > 2000/microliter

• Administer HEPZATO via the HEPZATO KIT Hepatic Delivery System only to patients weighing 35 kg or greater due to potential size limitations with respect to percutaneous catheterization.
• HEPZATO, a component of the HEPZATO KIT, is administered by infusion into the hepatic artery (see IFU) every 6 to 8 weeks for up to 6 total infusions.
• The recommended HEPZATO dose is 3 mg/kg based on ideal body weight (IBW), as calculated per Table 1 below, with a maximum of 220 mg during a single treatment.

Table 1: Calculation of IBW for HEPZATO Dosing

	Height	Ideal Body Weight
Men	≥ 152 cm	52 kg + (0.75 kg/cm of height greater than 152 cm)
	< 152 cm	52 kg – (0.75 kg/cm of height less than 152 cm)
Women	≥ 152 cm	49 kg + (0.67 kg/cm of height greater than 152 cm)
	< 152 cm	49 kg – (0.67 kg/cm of height less than 152 cm)

A dosage reduction to 2 mg/kg is recommended for subsequent treatments for the following reasons:

• Grade 4 neutropenia of > 5 days duration despite growth factor support or associated with neutropenic fever;
• Grade 4 thrombocytopenia of > 5 days duration or associated with a hemorrhage that required a transfusion;

HEPZATO administered with the HEPZATO KIT should be discontinued if patients have life threatening or HEPZATO-related persistent toxicity that has not resolved to Grade 2 or less by 8 weeks following treatment.

Refer to the HEPZATO KIT Hepatic Delivery System IFU for further details and instructions.

Reconstitute and dilute melphalan immediately prior to beginning intra-arterial infusion.

Reconstituted and diluted solutions of HEPZATO are unstable. No more than 60 minutes should elapse from reconstitution and completion of the intra-hepatic infusion of the diluted HEPZATO solution. A citrate derivative of melphalan has been detected in reconstituted HEPZATO in 30 minutes, and nearly 1% of labeled strength of melphalan hydrolyzes every 10 minutes when reconstituted HEPZATO is further diluted in 0.9% Sodium Chloride. A precipitate forms if the reconstituted solution is stored at 5°C. Do not refrigerate HEPZATO once reconstituted.

HEPZATO is a hazardous drug¹. Follow applicable special handling and disposal procedures.

Reconstitution and Dilution Instructions:

• Rapidly (in 5 seconds or less) inject 10 mL of the supplied sterile diluent [see Dosage Forms and Strengths (3.0)] into the HEPZATO 50 mg vial using a sterile needle (20-gauge or larger) and syringe. The resulting solution will contain melphalan 5 mg/mL
• Immediately shake the vial vigorously until a clear solution is obtained. No more than five (5) seconds should elapse between the discharge of the syringe and the commencement of shaking.
• Immediately further dilute the required dose with the provided 0.9% sodium chloride injection, United States Pharmacopeia (USP), to a concentration not greater than 0.45 mg/mL, as follows
  • HEPZATO doses up to 110 mg:
    Dilute in 250 mL of 0.9% sodium chloride injection
  • HEPZATO doses 111 mg to 220 mg:
    Divide the total dose equally into 2 and dilute each in 250 mL of 0.9% sodium chloride injection (for example, if the total dose is 200 mg, dilute 100 mg in each 250 mL 0.9% sodium chloride injection)
  • Visually inspect parenteral drug products for particulate matter and discoloration prior to administration, whenever solution and container permit. If particulates and discolorations are noted, the product should not be used.
  • Administer diluted HEPZATO intra-arterially as described in the IFU. Complete the infusion within 30 minutes, followed by a 30-minute washout period. Refer to the IFU for additional administration procedures.

HEPZATO (melphalan) is supplied in the HEPZATO KIT that contains the following:

• Melphalan for injection: 5 single dose, clear glass vials for injection, containing 50 mg white to pale yellow lyophilized powder, intended for reconstitution with the supplied diluents

HEPZATO and the HEPZATO KIT are contraindicated in patients with:

• Active intracranial metastases or brain lesions with a propensity to bleed
• Liver failure, portal hypertension, or known varices at risk for bleeding
• Surgery or medical treatment of the liver in the previous 4 weeks
• Uncorrectable coagulopathy
• Inability to safely undergo general anesthesia, including active cardiac conditions including, but not limited to, unstable coronary syndromes (unstable or severe angina or myocardial infarction), worsening or new-onset congestive heart failure, significant arrhythmias, or severe valvular disease
• History of allergies or known hypersensitivity to melphalan
• History of allergies or known hypersensitivity to a component or material utilized within the HEPZATO KIT including
  • History of allergy to natural rubber latex
  • History of allergy or hypersensitivity to heparin or presence of heparin-induced thrombocytopenia (HIT)
  • History of severe allergic reaction to iodinated contrast not controlled by premedication with antihistamines and steroids

Hemorrhage, hepatocellular injury, and thromboembolic events have been observed when HEPZATO has been administered via hepatic intra-arterial administration. Administration of HEPZATO requires general anesthesia and extracorporeal bypass of circulation which may cause life threatening or fatal adverse effects. Ensure the patient is euvolemic but do not overhydrate the patient. Monitor for these peri-procedural complications during the procedure and for at least 72 hours following the procedure.

To mitigate the risk of thromboembolic events, administer anticoagulation as described in the IFU during the procedure.

Due to the risk of bleeding, do not use in patients with uncorrectable coagulopathies and delay treatment with the HEPZATO KIT for at least 4 weeks after surgery or other medical procedure involving the liver. Platelets and clotting factors may be removed during the HEPZATO KIT procedure. Monitor platelets and coagulation parameters as described in the IFU. If life-threatening bleeding occurs during the procedure, reverse anticoagulation as described in the IFU and correct coagulopathy as appropriate. Discontinue anticoagulation with warfarin or other oral anticoagulants prior to the procedure; resume when hemostasis has been restored after the procedure, provided no bleeding complications have been observed. Refer to the Prescribing Information of the anticoagulant agent for bridging recommendations for anti-coagulation prior to surgical procedures. Discontinue drugs affecting platelet function such as aspirin, non-steroidal anti-inflammatory drugs, or other anti-platelet drugs one week before the procedure.

Patients with abnormal hepatic vascular (especially arterial supply) or biliary (especially re-implantation of bile duct) anatomy or gastric acid hypersecretion syndromes may be at increased risk of peri-procedural complications or other severe adverse reactions. Screen patients for a history of prior surgeries involving the bile duct to assess whether the patient is an appropriate candidate for HEPZATO KIT and monitor patients for adverse reactions following HEPZATO KIT administration.

Procedure-related reductions in blood pressure including severe hypotension can occur during the HEPZATO KIT procedure. Closely monitor blood pressure during the procedure. Patients may require fluid support and vasopressors. To reduce the risk of severe hypotension, assess hypothalamic-pituitary-adrenal axis function, and temporarily discontinue ACE-inhibitors, calcium channel blockers, or alpha-1-adrenergic blockers for at least 5 half-lives prior to treatment with the HEPZATO-KIT. If necessary, use other short-acting antihypertensive drugs to manage blood pressure during the peri-procedure period.

The HEPZATO KIT is only available through a restricted program under a REMS, because of the risk of severe peri-procedural complications including hemorrhage, hepatocellular injury, and thromboembolic events defined in the REMS. The HEPZATO KIT should only be used by trained healthcare providers [see Warnings and Precautions (5.1)].

Important requirements of the HEPZATO KIT REMS include:

• Healthcare settings that dispense and administer HEPZATO KIT must be enrolled, certified, and comply with the REMS requirements.
• Certified healthcare facilities must ensure that healthcare providers who perform the Percutaneous Hepatic Perfusion (PHP) procedure are trained on the use of HEPZATO KIT and must only dispense HEPZATO when authorized to do so by the REMS.
• Certified healthcare facilities must ensure that patients are assessed for severe peri-procedural complications during the procedure and for at least 72 hours following the procedure.

Further information is available at www.HEPZATOKITREMS.com or contact Delcath Systems at 1-833-632-0457.

Hematologic adverse reactions, including thrombocytopenia, anemia, and neutropenia have been reported in patients treated with HEPZATO. The risk of hematologic adverse reactions may be increased in patients who have received prior chemotherapy, bone irradiation, or who have compromised bone marrow function.

In the 95 patients who received HEPZATO in the FOCUS trial, 68% had Grade 3 or 4 myelosuppression. A total of 55%, 33%, and 30% experienced Grade 3 or 4 thrombocytopenia, anemia, and neutropenia, respectively. Median time to thrombocyte nadir was 13 days (range: 3-33) after treatment with median recovery in 20 days (range: 4-29) after treatment. Median time to hemoglobin nadir was 10 days (range: 3-21) after treatment with median recovery in 13 days (range: 4-28) after treatment. Median time to neutrophil nadir was 11 days (range: 3-36) after treatment with median recovery in 17 days (range: 9-36) after treatment.

Monitor patients for severe infections, bleeding, and symptomatic anemia. Only administer HEPZATO in patients with platelets >100,000/microliter, hemoglobin ≥10.0 gm/dL and neutrophils >2,000/microliter. Administer transfusions or growth factors as appropriate [see Dosage and Administration (2.1)].

Hypersensitivity reactions, including anaphylaxis, have occurred in approximately 2% of patients who received an intravenous (IV) formulation of melphalan. These reactions with melphalan are characterized by urticaria, pruritus, edema, skin rashes, and in some patients, tachycardia, bronchospasm, dyspnea, and hypotension. Hypersensitivity can occur in patients with or without prior exposure to IV or oral melphalan.

When a hypersensitivity reaction is observed, immediately terminate the hepatic arterial HEPZATO infusion and administer necessary supportive care [see Contraindications (4)].

Patients with a history of allergic reactions to iodinated contrast may experience hypersensitivity reactions, including anaphylaxis, during treatment with the HEPZATO KIT. Premedicate patients with a history of allergic reaction to iodinated contrast prior to treatment with HEPZATO KIT. Do not administer HEPZATO KIT in patients with a history of severe allergic reactions or anaphylaxis to iodinated contrast [see IFU, see Contraindications (4)].

Gastrointestinal adverse reactions including nausea and vomiting, abdominal pain, and diarrhea are common, and occurred in 84% of patients treated with HEPZATO in the FOCUS trial. Administer a proton pump inhibitor the day prior to and the morning of the procedure. If anti-emetic treatment is required, pre-medicate with anti-emetic therapy in subsequent cycles.

Melphalan has been shown to cause chromatid or chromosome damage in humans. Secondary malignancies, including acute nonlymphocytic leukemia, myeloproliferative syndrome, and carcinoma, have been reported in patients with cancer treated with intravenous alkylating drugs including melphalan. Some patients also received other chemotherapeutic agents or radiation therapy. Precise quantification of the risk of acute leukemia, myeloproliferative syndrome, or carcinoma is not possible. Published reports of leukemia in patients who have received oral or IV melphalan (and other alkylating drugs) suggest that the risk of leukemogenesis increases with chronicity of treatment and with cumulative dose [see Nonclinical Toxicology (13.1)].

Based on animal studies and its mechanism of action, melphalan can cause fetal harm when administered to a pregnant woman. Melphalan is genotoxic, targets actively dividing cells, and was embryolethal and teratogenic in rats. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with HEPZATO and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with HEPZATO and for 3 months after the last dose [see Use in Specific Populations (8.1, 8.3), Nonclinical Toxicology (13.1)].

Melphalan-based chemotherapy regimens have been reported to cause suppression of ovarian function in premenopausal women, resulting in persistent amenorrhea in approximately 9% of patients. Reversible or irreversible testicular suppression has also been reported [see Use in Specific Populations (8.3)].

Below are adverse reactions associated with HEPZATO KIT. Additional adverse reactions related to the procedure and/or medical device are described in further detail in the HEPZATO KIT IFU. The following clinically significant adverse reactions are described elsewhere in the labeling:

• Peri-procedural complications [see Warnings and Precautions (5.1)]
• Myelosuppression [see Warnings and Precautions (5.3)]
• Hypersensitivity Reactions [see Warnings and Precautions (5.4)]
• Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.5)]
• Secondary Malignancies [see Warnings and Precautions (5.6)]

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug-device combination cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The adverse drug reactions (ADRs) described in this section were identified from the FOCUS trial. FOCUS was a multicenter trial that evaluated HEPZATO (melphalan) administered via the HEPZATO KIT in patients with unresectable hepatic metastases from uveal melanoma. In the FOCUS trial, a total of 95 patients were enrolled into the HEPZATO KIT arm, of which 91 patients received treatment with HEPZATO.

Serious adverse reactions occurred in 45% of patients who received HEPZATO. Serious adverse reactions occurring in ≥ 2% of patients were thrombocytopenia (10%), neutropenia (8%), febrile neutropenia (7%), platelet count decreased (6%), leukopenia (4.2%), cardiac arrest (3.2%), neutrophil count decreased (2.1%), hypoxia (2.1%), pleural effusion (2.1%), pulmonary edema (2.1%), and deep vein thrombosis (2.1%). Fatal adverse reactions occurred in 3 (3.2%) patients who were treated with HEPZATO; these included cardiac arrest, acute hepatic failure and bacterial peritonitis.

HEPZATO was permanently discontinued due to adverse reactions in 18% of patients with neutropenia being the most common adverse reaction (3.2%) requiring permanent discontinuation.

Dose reductions due to an adverse reaction occurred in 14% of patients who received HEPZATO. Adverse reactions which required dose reductions occurring in ≥ 2% of patients were platelet count decreased (6%), neutropenia (4.2%), anemia (2.1%), and thrombocytopenia (2.1%).

Adverse reactions that required dosage interruption in ≥ 2% of patients who received HEPZATO were platelet count decreased (6%), neutropenia (5%), thrombocytopenia (3.2%), anemia (3.2%) and febrile neutropenia (2.1%).

The most common (≥20%) adverse reactions or laboratory abnormalities reported in patients treated with HEPZATO were thrombocytopenia (65%), fatigue (65%), anemia (63%), nausea (57%), musculoskeletal pain (46%), leukopenia (46%), abdominal pain (39%), neutropenia (35%), vomiting (35%), increased alanine aminotransferase (32%), prolonged activated partial thromboplastin time (28%), increased aspartate aminotransferase (28%), increased blood alkaline phosphatase (27%), and dyspnea (23%).

Table 2 and Table 3 summarize adverse reactions and laboratory abnormalities, respectively, that occurred in FOCUS.

Risk Summary

Based on animal studies and its mechanism of action, melphalan can cause fetal harm when administered to a pregnant woman, including teratogenicity and/or embryo-fetal lethality [see Clinical Pharmacology (12.1)]. Melphalan is a genotoxic drug and can cause chromatid or chromosome damage in humans [see Nonclinical Toxicology (13.1)]. In animal studies, melphalan was embryolethal and teratogenic in rats at doses below the recommended clinical doses [see Data]. Advise a pregnant woman of the potential risk to a fetus.

The background risk of major birth defects and miscarriage for the indicated populations are unknown. However, the background risk in the United States general population of major birth defects is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies.

Data

Animal Data

Adequate animal studies have not been conducted with IV melphalan. Melphalan was embryolethal and teratogenic in rats following oral administration of 6 to 18 mg/m²/day for ten (10) days (0.05 to 0.16 times the recommended clinical dose of 3 mg/kg or 111 mg/m²/day) and intraperitoneal administration of 18 mg/m² (0.16 times the highest recommended clinical dose). Malformations resulting from melphalan administration included alterations of the brain (underdevelopment, deformation, meningocele, and encephalocele) and eye (anophthalmia and microphthalmos), reduction of the mandible and tail, and hepatocele (exomphaly).

Risk Summary

It is not known whether melphalan is present in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing children from melphalan, breastfeeding is not recommended during treatment with melphalan and for one week after the last dose.

Contraception

Females

Advise females of reproductive potential to use effective contraception during treatment with HEPZATO and for 6 months after the last dose.

Males

HEPZATO administration may damage spermatozoa and testicular tissue, resulting in possible genetic fetal abnormalities. Advise males with female partners of reproductive potential to use effective contraception during treatment with HEPZATO and for 3 months after the last dose [see Nonclinical Toxicology (13.1)].

Infertility

Females

Melphalan causes suppression of ovarian function in premenopausal women, resulting in amenorrhea in a significant number of patients.

Males

Reversible and irreversible testicular suppression has been reported in male patients after administration of melphalan.

Exposure-Response

Melphalan exposure-response relationships and the time course of pharmacodynamic response following administration of HEPZATO via the Hepatic Delivery System are not fully characterized.

Distribution

The melphalan plasma protein binding is approximately 78% following administration of HEPZATO. Serum albumin accounts for approximately 40% to 60% and α₁-acid glycoprotein approximately 20% of the plasma protein binding.

Elimination

The median terminal elimination phase half-life of 1.07 hours that is consistent with IV melphalan administration.

Metabolism:

Melphalan is primarily metabolized by hydrolysis to inactive metabolites.

Excretion:

Liver uptake and removal of melphalan by isolation of hepatic venous blood and subsequent filtration by HDS are the two main processes for reducing the amount of melphalan that is available systemically following administration of HEPZATO. HDS reduced systemic melphalan exposure with a mean (SD) filter efficiency of 82.7% (14.4%) for the total filtration period.

Systemic melphalan is eliminated by renal excretion of parent drug and metabolites.

Specific Populations

No clinically significant differences in the pharmacokinetics of melphalan were observed based on body weight (43 - 150 kg), creatinine clearance (> 50 mL/min), or hepatic parameters (ALT (7 - 157 IU/L), AST (11 - 90 IU/L), or bilirubin (0.06 - 1.5 mg/dL) following administration of HEPZATO KIT.

Study in Patients with Uveal Melanoma

The efficacy of HEPZATO in hepatic-dominant metastatic uveal melanoma was based on the results from 91 patients who received HEPZATO via the HEPZATO KIT in the FOCUS Study (NCT02678572), a multicenter, open-label trial. To be eligible for enrollment, patients were required to have metastatic uveal melanoma with metastases predominately involving the liver (liver dominant). Limited extrahepatic disease in the bone, subcutaneous sites, lymph nodes, or lung was permitted if the life-threatening component of the uveal melanoma was in the liver and the extrahepatic disease was amenable to resection or radiation and had a defined treatment plan. Patients with metastases in more ≥ 50% of the liver parenchyma, unable to undergo general anesthesia, ECOG ≥2, platelets < 100,000/microliter, absolute neutrophil count < 1,500/microliter, hemoglobin < 10 gm/dL, Child-Pugh Class B or C cirrhosis, or hepatitis B or C infection were excluded.

Patients received 3 mg/kg of melphalan based on ideal body weight (IBW, maximum total dose of 220 mg) administered intraarterially using the Hepatic Delivery System (HDS) every 6-8 weeks for up to 6 infusions. The median number of infusions administered per patient was 4 (range: 1-6). Thirty-seven percent (37%) of the 91 patients treated received the maximum of six infusions of treatment.

The major efficacy outcome measures were objective response rate (ORR) and duration of response (DoR) using computed tomography (CT) or magnetic resonance imaging (MRI) assessed by an independent central review committee (IRC) using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.

The median age of patients was 61 years (range 20 to 78), 52% were female, 95% were White, 5% unavailable, and all patients had Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Ninety-five percent (95%) of enrolled patients had either 2 or 3 hepatic lesions. Seventy-nine percent (79%) of patients had <25% liver involvement. Thirty percent of the treated patients had extra-hepatic lesions, of which 20% had 1 extrahepatic lesion and 10% had 2 or more; overall 12% of patients had lung, 11% soft tissue/subcutaneous, 5% lymph node, and 4% had bone involvement. Forty-three percent (43%) of patients underwent prior therapy for metastatic disease, including systemic therapy (25%), other surgeries or procedures (14%), and radiation (11%).

The efficacy results of HEPZATO treatment are summarized in Table 4.

120070.A

Melphalan can cause fetal harm when administered to a pregnant woman. Verify the pregnancy status of females of reproductive potential prior to initiating HEPZATO [see Use in Specific Populations (8.1)].

The safety and effectiveness in pediatric patients have not been established.

Clinical studies of HEPZATO did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In the FOCUS trial, 30 of the 91 patients (33%) were 65 years and older.

No information on melphalan overdosage is available following administration of HEPZATO. Overdoses resulting in death have been reported following treatment with high intravenous (IV) doses of melphalan.

Overdoses via the IV route, including doses up to 290 mg/m² (approximately 7.5 mg/kg IBW), have produced the following symptoms: severe nausea and vomiting, decreased consciousness, convulsions, muscular paralysis, and cholinomimetic effects. Severe mucositis, stomatitis, colitis, diarrhea, and hemorrhage of the gastrointestinal tract occur at high IV doses (>100 mg/m² or approximately 2.6 mg/kg IBW). Elevations in liver enzymes and veno-occlusive disease occur infrequently. Significant hyponatremia caused by an associated inappropriate secretion of antidiuretic hormone syndrome has been observed. Nephrotoxicity and adult respiratory distress syndrome have been reported.

The principal toxic effect is bone marrow suppression. Hematologic parameters should be closely followed for three (3) to six (6) weeks. General supportive measures together with appropriate blood transfusions and antibiotics should be instituted as deemed necessary by the physician. General supportive measures, together with appropriate blood and platelet transfusions, should be instituted if necessary and consideration given to hospitalization, antibiotic cover, and the use of hematological growth factors.

This drug is not removed from systemic plasma to any significant degree by hemodialysis or hemoperfusion.

Melphalan, is a bifunctional alkylating drug that is active against selected human neoplastic diseases. Melphalan is available as melphalan hydrochloride salt. The chemical name of melphalan hydrochloride is 4-[bis(2-chloroethyl)amino]-L-phenylalanine hydrochloride. The molecular formula is C₁₃H₁₈Cl₂N₂O₂.HCl and the molecular weight is 341.67.

Figure (Hep11 0001 01)

Melphalan is practically insoluble in water and has a pKa1 of ~2.5.

HEPZATO, for injection, is supplied as a sterile, nonpyrogenic, freeze-dried white to pale yellow freeze-dried cake/ powder. Each single dose vial contains melphalan 50 mg, equivalent to 56 mg of melphalan hydrochloride and 20 mg povidone.

HEPZATO (melphalan) is reconstituted using the sterile diluent provided. Each vial of sterile diluent contains sodium citrate 0.2 g, propylene glycol 6.0 mL, ethanol (96%) 0.52 mL, and water for injection to a total of 10 mL.

HEPZATO (melphalan) for use with the hepatic delivery system is administered intra-arterially.

Melphalan is an alkylating drug of the bischloroethylamine type. As a result, its cytotoxicity appears to be related to the extent of its interstrand cross-linking with DNA, probably by binding at the N7 position of guanine. It is active against both resting and rapidly dividing tumor cells.

Geometric mean of systemic melphalan maximum concentration (C_max) is 2.4 (%CV 3.0) mcg/mL and the AUC_0-last was 1.8 (%CV 1.1) mcg*hr/mL.

The melphalan median (range) time to C_max (T_max) is 0.57 (0.05 – 1.18) hours following administration of HEPZATO.

Adequate and well-controlled carcinogenicity studies have not been conducted in animals. However, intraperitoneal (IP) administration of melphalan in rats (5.4 to 10.8 mg/m²) and in mice (2.25 to 4.5 mg/m²) 3 times per week for 6 months followed by 12 months post-dose observation produced peritoneal sarcoma and lung tumors, respectively.

Intramuscular administration of melphalan at 6 and 60 mg/m² produced structural aberrations of the chromatid and chromosomes in bone marrow cells of Wistar rats.

HEPZATO KIT™

HEPZATO (melphalan) for Injection/

Hepatic Delivery System

COMPLETE REQUIRED REMS TRAINING BEFORE USING THIS DEVICE FOR THE FIRST TIME. ENSURE YOU COMPLETELY READ AND UNDERSTAND THE INSTRUCTIONS FOR USE.

(c) DESCRIPTION OF SYSTEM COMPONENTS

HEPZATO KIT™ consists of a closed circuit of catheters and drug-specific filters utilized to deliver Hepzato (melphalan) to the hepatic artery and to lower the concentration of melphalan in the blood before it is returned to systemic circulation. A schematic overview of how the Hepatic Delivery System components work together is presented in Figure 1: Assembled System. The system is designed to be used with a Medtronic Bio-Console^® 560 Speed Controller System and TX50P Flow Transducer.

1. Double Balloon Catheter (DBC) -- 16F (shaft) polyurethane double balloon catheter that is placed in the retro-hepatic inferior vena cava to isolate the hepatic venous blood and transport it to the Extracorporeal Hemofiltration Circuit for filtration. The catheter has one large (central) drainage lumen and four accessory ports. Due to variation in the length of a patient's retro-hepatic segment of the inferior vena cava and relative positions of hepatic and renal veins, the Double Balloon Catheter is available in two different balloon configurations: 50 mm or 62 mm between the two balloons.

Using pre-operative computed tomography (CT) imaging, or by performing an inferior vena cavogram prior to placement of the Double Balloon Catheter, estimate the length of the retro-hepatic segment of the inferior vena cava and the relative positions of hepatic and renal veins in order to determine the optimum Double Balloon Catheter balloon spacing: 50mm or 62mm.

Two of the accessory ports are used to inflate low-pressure occlusion balloons, which are inflated independently to occlude the inferior vena cava above and below the hepatic veins. When inflated, the cephalic (superior – blue port) balloon obstructs the inferior vena cava above the hepatic veins and the caudal (inferior – yellow port) balloon obstructs the inferior vena cava below the hepatic veins, thus isolating hepatic venous blood in the fenestrated segment between the balloons.

The large drainage lumen with a quick connect fitting is a conduit to the fenestrations between the two occlusion-balloons. The fenestrations allow the hepatic venous blood to flow into the drainage lumen and exit the catheter at the proximal end.

The third accessory (translucent) port labeled “CONTRAST” is for injections of iodinated contrast medium through the fenestrations, to check catheter position.

The fourth accessory port (white) is used for over-the-guidewire (OTW) introduction and positioning of the catheter in the retro-hepatic inferior vena cava. This lumen also has a small port opening along the catheter shaft positioned inferior to the caudal balloon and exits at the distal tip, to allow inferior vena cava blood, proximal to the caudal balloon, to bypass the occluded segment of the inferior vena cava and flow into the right atrium.

2. Accessory Pack

• 9F and 13F Dilator Set --These over-the-wire dilators are used to widen the subcutaneous space and venous entry site in preparation for the placement of the 18F Introducer Set.
• 18F Introducer Set (Sheath and Dilator) -- The 18F introducer sheath and coaxial dilator are to be placed over a wire; the dilator is removed, and the sheath is available for the insertion of the Double Balloon Catheter or the 18F Obturator.
• 18F Obturator -- An 18F obturator is used to occlude and support the 18F sheath lumen when it is not in use, and upon removal of the Double Balloon Catheter at the end of the procedure.
• 5F Introducer Set (Sheath and Dilator) -- A 5F hemostasis sheath is used to facilitate the introduction of the 5F Infusion Catheter through the femoral artery.
• 10F Introducer Set (Venous Return Sheath) -- A 10F sheath used to return the filtered hepatic venous blood through the internal jugular vein. A 3-way high-flow stopcock is included as part of the 10F Introducer Set. The high-flow stopcock is attached to the Venous Return Sheath and then to the male connector of the Extracorporeal Hemofiltration Circuit, if required. This sheath may also be used for hydration.

3. 5F Infusion Catheter -- 5F arterial catheter is used to deliver Hepzato into the proper hepatic artery or it can be used to coaxially introduce a microcatheter, if, at the discretion of the Interventional Radiologist, a microcatheter is preferred for selective catheter tip placement for the drug infusion.

4. Delcath Hemofiltration Dual Filter Cartridge -- One single-use Dual Filter Cartridge designed with the filter cartridges arranged in parallel to lower the concentration of Hepzato (melphalan) in systemic circulation. The cartridge frame comes with a built-in pole clamp.

Filter mechanism of action: The filter is composed of activated carbon for adsorption and removal of HEPZATO. The pore structure of the filter media along with its particle size and shape contribute to rapid HEPZATO adsorption where large quantities (70 cc/100 g of carbon with melphalan) are adsorbed during a first pass through the filter Flow rates should be between 0.4 Liters/minute to 0.8 Liters/minute, to ensure the appropriate removal of the HEPZATO from the blood during the 30-minute infusion period and continue to remove residual drug during the 30-minute wash out period.

5. Extracorporeal Hemofiltration Circuit (EFC) -- The Extracorporeal Hemofiltration Circuit is used to transport the hepatic venous blood, which has been isolated by the Double Balloon Catheter and aspirated into the fenestration lumen, through the Hemofiltration Cartridges and back to the patient through the Venous Return Sheath. Connections are provided for infusion of normal saline. This circuit includes:

(d) INDICATIONS FOR USE

HEPZATO KIT™, containing HEPZATO for injection, is indicated as a liver-directed treatment for adult patients with uveal melanoma with unresectable hepatic metastases affecting less than 50% of the liver and no extrahepatic disease or extrahepatic disease limited to the bone, lymph nodes, subcutaneous tissues, or lung that is amenable to resection or radiation.

(e) WARNING: PERI-PROCEDURAL COMPLICATIONS, MYELOSUPPRESSION

Severe peri-procedural complications including hemorrhage, hepatocellular injury, and thromboembolic events may occur via hepatic intra-arterial administration of HEPZATO. Assess patients for these adverse reactions during and for at least 72 hours following administration of HEPZATO. HEPZATO KIT is available only through a restricted program under a Risk Evaluation and Mitigation Strategy called the HEPZATO KIT REMS. Myelosuppression with resulting severe infection, bleeding, or symptomatic anemia may occur with HEPZATO. Monitor hematologic laboratory parameters and delay additional cycles of HEPZATO therapy until blood counts have improved.

(f) CONTRAINDICATIONS

HEPZATO KIT is contraindicated in patients with:

• Active intracranial metastases or brain lesions with a propensity to bleed
• Liver failure, portal hypertension, or known varices at risk for bleeding
• Surgery or medical treatment of the liver in the previous 4 weeks
• Uncorrectable coagulopathy
• Inability to safety undergo general anesthesia, including active cardiac conditions including, but not limited to, unstable coronary syndromes (unstable or severe angina or myocardial infarction), worsening or new-onset congestive heart failure, significant arrhythmias, or severe valvular disease

• History of allergies or known hypersensitivity to a component or material utilized within the HEPZATO KIT including:
  • History of allergy to natural rubber latex
  • History of allergy or hypersensitivity to heparin or presence of heparin-induced thrombocytopenia (HIT)
  • History of severe allergic reaction to iodinated contrast not controlled by premedication with antihistamines and steroids

  (g) WARNINGS AND PRECAUTIONS

  PLEASE CAREFULLY READ AND UNDERSTAND THE LIST OF WARNINGS AND PRECAUTIONS BELOW AS SERIOUS INJURY, ILLNESS OR DEATH OF THE PATIENT CAN OCCUR IF THESE WARNINGS AND PRECAUTIONS ARE NOT PROPERLY FOLLOWED.

  Peri-Procedural Complications

  Hemorrhage, hepatocellular injury, and thromboembolic events have been observed when HEPZATO has been administered via hepatic intra-arterial administration. Administration of HEPZATO KIT requires general anesthesia and extracorporeal bypass of circulation which may cause life threatening or fatal adverse effects. Ensure the patient is euvolemic but do not overhydrate the patient. Monitor for these peri-procedural complications during the procedure and for at least 72 hours following the procedure.

  To mitigate the risk of thromboembolic events, administer anticoagulation as described in the IFU during the procedure.

  Due to the risk of bleeding, do not use in patients with uncorrectable coagulopathies and delay treatment with the HEPZATO KIT for at least 4 weeks after surgery or other medical procedure involving the liver. Platelets and clotting factors may be removed during the HEPZATO KIT procedure. Monitor platelets and coagulation parameters as described in the IFU. If life-threatening bleeding occurs during the procedure, reverse anticoagulation as described in the IFU and correct coagulopathy as appropriate. Discontinue anticoagulation with warfarin or other oral anticoagulants prior to the procedure until hemostasis has been restored after the procedure and no bleeding complications have been observed. Refer to the Prescribing Information of the anticoagulant agent for bridging recommendations for anti-coagulation prior to surgical procedures. Discontinue drugs affecting platelet function such as aspirin, non-steroidal anti-inflammatory drugs, or other anti-platelet drugs one week before the procedure.

  Patients with abnormal hepatic vascular (especially arterial supply) or biliary (especially re-implantation of bile duct) anatomy or gastric acid hypersecretion syndromes may be at increased risk of peri-procedural complications or other severe adverse reactions. Screen patients for a history of prior surgeries involving the bile duct to assess whether the patient is an appropriate candidate for HEPZATO KIT and monitor patients for adverse reactions following HEPZATO KIT administration.

  Procedure-related reductions in blood pressure including severe hypotension can occur during the HEPZATO KIT procedure. Closely monitor blood pressure during the procedure. Patients may require fluid support and vasopressors. To reduce the risk of severe hypotension, assess hypothalamic-pituitary-adrenal axis function, and temporarily discontinue ACE-inhibitors, calcium channel blockers, or alpha-1-adrenergic blockers for at least 5 half-lives prior to treatment with the HEPZATO-KIT. If necessary, use other short-acting antihypertensive drugs to manage blood pressure during the peri-procedure period.

  HEPZATO KIT REMS Program

  The HEPZATO KIT is only available through a restricted program under a REMS, because of the risk of severe peri-procedural complications including hemorrhage, hepatocellular injury, and thromboembolic events defined in the REMS. The HEPZATO KIT should only be used by trained healthcare providers [see HEPZATO USPI Warnings and Precautions (5.2)].

  Important requirements of the HEPZATO KIT REMS include:

  Healthcare settings that dispense and administer HEPZATO KIT must be enrolled, certified, and comply with the REMS requirements.

  Certified healthcare facilities must ensure that healthcare providers who perform the Percutaneous Hepatic Perfusion (PHP) procedure are trained on the use of HEPZATO KIT and must only dispense HEPZATO when authorized to do so.

  Certified healthcare facilities must ensure that patients are assessed for severe peri-procedural complications during the procedure and for at least 72 hours following the procedure.

  Further information is available at www.HEPZATOKITREMS.com or contact Delcath Systems at 1-833-632-0457.

  Myelosuppression

  Hematologic adverse reactions, including thrombocytopenia, anemia, and neutropenia have been reported in patients treated with HEPZATO. The risk of hematologic adverse reactions may be increased in patients who have received prior chemotherapy, bone irradiation, or who have compromised bone marrow function.

  In the 95 patients who received HEPZATO KIT in the FOCUS trial, 68% had Grade 3 or 4 myelosuppression. A total of 55%, 33%, and 30% experienced Grade 3 or 4 thrombocytopenia, anemia, and neutropenia, respectively. Median time to thrombocyte nadir was 13 days (range: 3-33) after treatment with median recovery in 20 days (range: 4-29) after treatment. Median time to hemoglobin nadir was 10 days (range: 3-21) after treatment with median recovery in 13 days (range: 4-28) after treatment. Median time to neutrophil nadir was 11 days (range: 3-36) after treatment with median recovery in 17 days (range: 9-36) after treatment.

  Monitor patients for severe infections, bleeding, and symptomatic anemia. Only administer HEPZATO in patients with platelets >100,000/microliter, hemoglobin ≥10.0 gm/dL and neutrophils >2,000/microliter. Administer transfusions or growth factors as appropriate [see HEPZATO USPI Dosage and Administration (2.1)].

  Hypersensitivity Reactions

  Hypersensitivity reactions, including anaphylaxis, have occurred in approximately 2% of patients who received an intravenous (IV) formulation of melphalan. These reactions with melphalan are characterized by urticaria, pruritus, edema, skin rashes, and in some patients, tachycardia, bronchospasm, dyspnea, and hypotension. Hypersensitivity can occur in patients with or without prior exposure to IV or oral melphalan.

  When a hypersensitivity reaction is observed, immediately terminate the hepatic arterial melphalan infusion and administer necessary supportive care [see HEPZATO USPI Contraindications (4), and Adverse Reactions (6.1)].

  Patients with a history of allergic reactions to iodinated contrast may experience hypersensitivity reactions, including anaphylaxis, during treatment with the HEPZATO KIT. Premedicate patients with a history of allergic reaction to iodinated contrast prior to treatment with HEPZATO KIT. Do not administer HEPZATO KIT in patients with a history of severe allergic reactions or anaphylaxis to iodinated contrast [see IFU contraindications and HEPZATO USPI Contraindications (4)].

  Gastrointestinal Adverse Reactions

  Gastrointestinal adverse reactions including nausea and vomiting, abdominal pain, and diarrhea are common, and occurred in 84% of patients treated with HEPZATO KIT in the FOCUS trial. Administer a proton-pump inhibitor (PPI) the day prior to and the morning of the procedure. If anti-emetic treatment is required, pre-medicate with anti-emetic therapy in subsequent cycles.

  Secondary Malignancies

  Melphalan has been shown to cause chromatid or chromosome damage in humans. Secondary malignancies, including acute nonlymphocytic leukemia, myeloproliferative syndrome, and carcinoma, have been reported in patients with cancer treated with intravenous alkylating drugs including melphalan. Some patients also received other chemotherapeutic agents or radiation therapy. Precise quantification of the risk of acute leukemia, myeloproliferative syndrome, or carcinoma is not possible. Published reports of leukemia in patients who have received oral or IV melphalan (and other alkylating drugs) suggest that the risk of leukemogenesis increases with chronicity of treatment and with cumulative dose [see HEPZATO USPI Nonclinical Toxicology (12.1)].

  Embryo-Fetal Toxicity

  Based on animal studies and its mechanism of action, melphalan can cause fetal harm when administered to a pregnant woman. Melphalan is genotoxic, targets actively dividing cells, and was embryolethal and teratogenic in rats. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with melphalan and for 6 months after the last dose. Advise males with female partners of reproductive potential to use effective contraception during treatment with HEPZATO and for 3 months after the last dose [see HEPZATO USPI Use in Specific Populations (8.1, 8.3), Nonclinical Toxicology (13.1)].

  Infertility

  Melphalan-based chemotherapy regimens have been reported to cause suppression of ovarian function in premenopausal women, resulting in persistent amenorrhea in approximately 9% of patients. Reversible or irreversible testicular suppression has also been reported [see HEPZATO USPI Use in Specific Populations (8.3)].

  (h) LOCATION OF PROCEDURE

  Figure (Hep11 0001 11)

  All medications and supportive measures must be determined and administered in accordance with each institution's policies, guidelines, procedures, and the HEPZATO KIT prescribing information.

  Before starting the procedure, confirm that all components of the HEPZATO KIT are available for assembly. Note: Certain components are not supplied by Delcath. Verify that the Medtronic pump is functioning properly (see pump operating manual for instructions on proper functionality).

  Hepatic Vascular Mapping - Angiography and Embolization

  To deliver HEPZATO to the whole liver and avoid inadvertent infusion of HEPZATO into the gastrointestinal or visceral branches, conduct a thorough hepatic artery angiogram and investigation of variant hepatic and gastric artery anatomy. In addition, embolization of certain branches supplying the gastro-intestinal tract may be necessary.

  WARNING If the perfusion of melphalan cannot be isolated from the systemic circulation, stop the drug infusion immediately.

  • Evaluate the portal vein for patency with late imaging during celiac and superior mesenteric arteriography. The presence of portal venous hypertension is a contraindication for treatment with HEPZATO via the HEPZATO KIT.
  • Completely examine the arterial supply to the liver and assess and understand its impact on chemotherapy infusion. Use of a selective micro-catheter may facilitate both embolization and subsequent drug infusion.
  • Assess liver blood supply and formulate a strategy for catheter placement to ensure drug infusion to the entire liver. If the risk assessment is unfavorable or the anatomic variation is too complex to allow whole liver or sequential lobar catheterization for safe delivery of melphalan, the procedure must not be performed.
  • Depending on vascular anatomy, a sequential lobar approach may be the best administration option which requires splitting the HEPZATO dose. This will require repositioning of the catheter during the procedure.
  • A whole liver infusion (dosing) approach will likely require embolization of the gastroduodenal artery but depends on its origin relative to the side branches of the distal proper hepatic artery. If the infusion catheter tip can be placed sufficiently distally to avoid retrograde reflux into the gastroduodenal artery, then the latter may not need to be embolized.

  Double Catheter Balloon Sizing

  • The double catheter balloon has two sizes representing the inter-balloon spacing distance. Spacing is based on hepatic venous anatomy and avoidance of renal vein occlusion. An inter balloon sizing should assure full isolation of all hepatic veins without occluding renal veins. Review computed tomography or magnetic resonance imaging to assess venous anatomy. Select KIT (balloon spacing) based on patient anatomy.

  Coagulation Studies

  • Perform coagulation studies pre-, peri- and post-procedure then repeat until normalized. Parameters tested must include:
    • - Partial Thromboplastin Time
    • - Prothrombin Time / International Normalized Ratio

    Blood Products

    Type and cross-match depending on institutional guidelines for:

    • Red blood cells
    • Fresh Frozen Plasma
    • Platelets
    • Cryoprecipitate

    Hydration

    • Pre procedural hydration is required if patient is determined to be hypovolemic. Do not over hydrate the patient pre-, peri- or post procedure. Overhydration has been associated with procedural and post-procedural complications.
    • Procedural hydration is required since 700 mL or more of blood will be displaced into the extracorporeal circulation. A mixture of colloids and crystalloids are used to replace this volume and steadily maintain mean arterial pressure above 60 mmHg during the procedure. Typically, total procedural fluid requirements range between 1,500 and 3,000 mL.
    • A Foley catheter is recommended to closely monitor fluid balance during hydration. If the patient is stable, remove within 24 hours after the procedure.

    Allopurinol

    • As a prophylaxis for electrolyte abnormalities, patients with more than 25% replacement of normal liver parenchyma with tumor are to be given allopurinol 300 mg/day orally beginning two (2) to three (3) days prior to percutaneous hepatic perfusion (PHP) with the Hepatic Delivery System and continuing two (2) to three (3) days following procedure.

    Proton Pump Inhibitors

    • Administer prophylactic proton pump inhibitors (for example: omeprazole, one 20 mg delayed release capsule by mouth) the day before and the morning of the procedure.

    Anticoagulation

    • The patient will be systemically anticoagulated with heparin during the procedure. Systemic anticoagulation is required to reduce the risk of thrombus formation including formation of thrombi that may impede free extracorporeal flow and filtration. Activated clotting time must be closely monitored to ensure adequate anticoagulation.
      • - Obtain the baseline activated clotting time value.
      • - Administer heparin to the patient only AFTER placement of the 18F (femoral vein), 10F (jugular vein), and 5F (femoral artery) sheaths. Ultrasound guidance and single anterior wall puncture technique are recommended during sheath placement to avoid bleeding complications.
      • - The patient must be fully heparinized prior to the insertion of the Double Balloon Catheter into the inferior vena cava. Begin with an initial intravenous bolus of heparin at 300 units/kg, dose adjusted to achieve activated clotting time.
      • - A minimum activated clotting time (ACT) of 400 seconds is necessary with a recommended ACT value > 450 seconds
      • - Evaluate activated clotting time frequently (approximately every 5 minutes) until adequate anti-coagulation is established (ACT > 400 seconds).
      • - DO NOT insert double balloon catheter into the patient Until ACT values are > 400 seconds.
      • - Maintain activated clotting time at > 400 seconds throughout the procedure, assessing ACT values every 15 – 30 minutes depending on the patient's response and administering intravenous heparin as needed.

      Anesthetic Management

      • Treatment must be administered with patients being monitored and under general anesthesia. Emergency resuscitation equipment must be available during the procedure.

      Blood Pressure Control

      • Expect significant procedure related decrease of blood pressure when the balloons occlude blood return from the inferior vena cava (decreased cardiac inflow) and when the filters are brought into the extracorporeal bypass circuit. The reasons for filter-related hypotension are multifactorial, but hypersensitivity to non-physiological surfaces (inflammatory response), significant reduction in venous return and preload, and possible removal of catecholamines by the filters may play a role. To aid blood pressure maintenance for extracorporeal bypass, the following actions are recommended per institutional practice:
        • - Pre-operative hydration and intra-procedural administration of colloids and crystalloids.
        • - Vasopressor use in accordance with institutional practices to elevate mean arterial pressure to a target >65 mmHg
        • Blood pressure must be constantly monitored throughout the procedure and maintained at levels required for adequate perfusion of critical end-organs (i.e., >65 mmHg).

        Drug Preparation and Delivery Planning

        • Prior to set up, provide pre-notification to the hospital pharmacy to be ready to reconstitute HEPZATO for injection.
        • HEPZATO reconstitution and delivery should be coordinated and timed so that the start of the infusion of the melphalan is within thirty minutes of preparation. Drug administration should be completed within 60 minutes of the start of preparation.
        • The filters should not be brought online until HEPZATO is in the procedure room. This minimizes filtration duration and associated complications.

                                          • (e) Administer an initial intravenous bolus of 300 units/kg of heparin. Heparin dose should be adjusted to achieve a minimum activated clotting time of 400 seconds prior to initiation of veno-venous bypass and balloon inflation.
                                          • (f) Evaluate activated clotting time frequently (approximately every 5 minutes) until adequate anti-coagulation is established (activated clotting time > 400 seconds). Maintain activated clotting time at > 400 seconds (preferably > 450 seconds) throughout the procedure, obtaining ACT values every 15-30 minutes depending on the patient's response, and administering intravenous heparin as needed.

                                            WARNING The start of the intra-arterial infusion of the drug solution must be within 30 minutes of its preparation.

                                            NOTE: TIMING OF CHEMOTHERAPEUTIC AGENT DELIVERY

                                            Time the request for delivery of the chemotherapeutic agent (HEPZATO) so that the start of the intra-arterial infusion of the drug solution is within thirty minutes of its preparation. Since preparation and delivery times vary, depending upon local practices, the timing of the request is critical and should be pre-arranged with the pharmacist. Ideally, the time to request chemotherapeutic agent from the pharmacy would be when the patient is heparinized just prior to placing the Double Balloon Catheter.

                                          • Insertion of the Double Balloon Catheter
                                            • (a) Flush the Double Balloon catheter with heparinized normal saline.
                                            • (b) Introduce the Double Balloon catheter through the 18F sheath. Under fluoroscopic guidance advance it over a guidewire into the inferior vena cava and position the catheter tip at the level of diaphragmatic hiatus. Do NOT expand the balloons.
                                            • (c) Upon successful placement, remove guidewire and create a heparin lock within the “OTW” lumen to maintain patency.

                                              • (d) Connect the extracorporeal hemofiltration circuit venous return line to the stopcock of the 10F venous return sheath placed in the jugular vein (Venous Return Sheath tubing has a red clamp), flush normal saline through the line. When all air is removed, and line is completely filled with normal saline turn stopcock to close the side port. Ensure the stopcock (at the venous return line to sheath connection) is fully open to minimize back pressure and maximize flow through the stopcock.

                                                • (a) Confirm filter inlet and outlet clamps are CLOSED (5, 6, 7 and 8) (red circles), per Figure 27.
                                                • (b) Open clamp 9 (blue circles).
                                                • (c) Confirm that clamps 3, 4, 10 and 11 are open (blue circles)
                                                • (d) Start pump and slowly increase RPM control to achieve a maximum allowable flow rate which does not cause flow induced vibration or exceed the 0.80 L/min flow rate or −250 mmHg pre-pump pressure.
                                                  • Flow rates of approximately 0.40 to 0.60 liters/minute are typical: 0.40 L/min is the minimum allowable and 0.80 L/min is the maximum allowable flow rate for this system.
                                                  • In-line pressure transducers should be used to monitor pressures:
                                                    • Pre pump pressure (suction side) should not be more negative than −250 mmHg, as lower pressures indicate possible catheter collapse or kink.
                                                    • Pre-cartridge pressures (pre-filter) should not exceed 200 mmHg, as higher pressures indicate increasing filter resistance potentially due to thrombus or a kinked return line. Check filters to assure free flow and return line for kinks.
                                                    • (e) The extracorporeal hemofiltration circuit is now established. Venous blood is aspirated from the central lumen through the fenestrations in the Double Balloon catheter. This blood flows through the Double Balloon catheter to the pump, through the bypass line, and returns to the patient through the venous return sheath.

                                                      CAUTION: Continuously monitor any perfusion related events including:

                                                        Vasoactive Agents Response Testing: Prior to expansion of either balloon (occlusion of inferior vena cava), administer vasoactive agent to assess patient responsiveness to this agent. It is recommended to use an infusion pump to quantify vasopressor doses during each procedural period. After balloons expansion, assess patient blood pressure for two (2) to five (5) minutes before proceeding. Significant decreases in blood pressure will occur within two (2) to five (5) minutes.

                                                        Continue to administer vasoactive agents to maintain mean blood pressures above 65 mmHg. Vasopressor agents are typically not required after the conclusion of the procedure.

                                                        • (a) Perfusionist must carefully monitor the flow rate during the balloon expansion.

                                                          WARNING Do NOT Over Expand the Balloons. Over Expansion of the Balloons Could Cause the Balloons to Burst which could result in Life-Threatening Injury.

                                                        • (c) Under fluoroscopy, partially expand the cephalad balloon with approximately 15 - 25 mL of dilute contrast media (e.g., 35% dilution) within the right atrium (the balloon will have a rounded appearance).
                                                        • (d) With the caudal balloon collapsed, slowly retract the Double Balloon catheter until the cephalad balloon is at the junction of the right atrium and inferior vena cava. If needed, further expand the cephalad balloon until indentation of the diaphragmatic hiatus is visible at the inferior margin (the balloon will acquire an acorn shaped appearance, see Figure 28). Do not expand balloons beyond required volume to achieve an adequate seal. Never advance or retract the Double Balloon catheter when both balloons are expanded. If resistance is met during manipulation, determine the cause of the resistance before proceeding.

                                                          WARNING Never stop blood flow through the extracorporeal hemofiltration circuit for more than 30 seconds.

                                                        • (f) With balloons expanded, perform a limited (retro-hepatic) inferior vena cavagram (using digital subtraction angiography technique) through the fenestrations. Prior to injection of contrast medium, reduce the pump speed to 1,000 RPM and clamp off the circuit. Inject iodinated contrast medium through the CONTRAST port to confirm that the catheter properly isolates hepatic venous flow between the balloons. The cephalad balloon must occlude the inferior vena cava just above the highest (closest to right atrium) hepatic vein, and the caudal balloon must occlude the inferior vena cava just below the lowest hepatic vein (above the renal veins) as shown in the radiographic image in Figure 29.
                                                        • (g) Re-establish flow through the extracorporeal hemofiltration circuit by unclamping the circuit and returning pump RPM to deliver previous flow rate.

                                                        • (h) If the Double Balloon catheter is not in the proper position, collapse both balloons (caudal balloon first) and then reposition the catheter, while maintaining flow in the extracorporeal hemofiltration circuit.
                                                        • (i) Once satisfactory position is attained (i.e., the isolated segment is well sealed), gently hold the proximal end of the Double Balloon catheter to prevent upward migration of the catheter into the right atrium. The catheter must be held due to forces that will push the balloon upwards towards the right atrium, and its position checked for the duration of the procedure (approximately 60 minutes).

                                                        CAUTION: Check Double Balloon catheter balloon positions fluoroscopically every four (4) to five (5) minutes during drug administration and filtration to ensure continued hepatic venous isolation.
