Grafapex Injection, Powder, Lyophilized, For Solution
FDA Label NDC 59137-365

• GRAFAPEX causes severe and prolonged myelosuppression at the recommended dosage.
• Hematopoietic stem cell transplantation is required to prevent potentially fatal complications of the prolonged myelosuppression. Monitor hematologic laboratory parameters[see Warnings and Precautions ( 5.1)] .

GRAFAPEX is indicated in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation in adult and pediatric patients 1 year of age and older with acute myeloid leukemia (AML).

GRAFAPEX is indicated in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation in adult and pediatric patients 1 year of age and older with myelodysplastic syndrome (MDS).

The recommended dosage of GRAFAPEX is 10 g/m ²by intravenous infusion given daily for three days, beginning on Day -4 prior to transplantation in combination with fludarabine as outlined in Table 1.

Premedicate patients with antiemetics prior to the first dose of GRAFAPEX and continue antiemetics on a fixed schedule through completion of treosulfan administration.

Reconstitute GRAFAPEX prior to intravenous infusion.

GRAFAPEX is a hazardous drug. Follow applicable special handling and disposal procedures. ¹

• Use aseptic technique to prepare GRAFAPEX.
• Calculate the dose, the total volume of reconstituted GRAFAPEX solution required, and the number of GRAFAPEX vials needed.
• Reconstitute each vial with 0.45% Sodium Chloride Injection, 0.9% Sodium Chloride Injection, 5% Dextrose Injection, or Sterile Water for Injection, in its original glass container using volumes described in Table 2 to obtain a final concentration of approximately 0.05 g/mL of GRAFAPEX. Reconstitution with Sterile Water for Injection alone is not recommended in children less than or equal to 12 years of age due to the resulting hypo-osmolarity of the final solution.

Table 2: Reconstitution Solution Volume

Strength	Volume
1 g/vial	20 mL
5 g/vial	100 mL

• Shake the vial(s) to dissolve.
• Inspect the reconstituted solution for discoloration and particulate matter. The reconstituted solution appears as a clear colorless solution. Solutions showing any sign of precipitation should not be used. In case that solubility issues occur, prolonged standing time or slight warming of the reconstituted solution (hand warm) may be useful.
• Determine the volume of 0.05 g/mL reconstituted solution needed based on the required dose. Reconstituted solutions of GRAFAPEX may be combined into a larger glass vial, ethylene-vinyl acetate (EVA) bag or polyolefin (PO) bag. Discard any unused portion left in the vial(s).

If not used immediately store reconstituted GRAFAPEX solution at room temperature 20°C to 25°C (68°F to 77°F) for up to 24 hours. Do not use if the solution contains a precipitate.

Do not refrigerate.

Infuse GRAFAPEX intravenously over 2 hours. Confirm patency of the intravenous line prior to infusion. Monitor for extravasation; if extravasation occurs, stop the infusion  [see Warnings and Precautions ( 5.4)] .

For injection: 1 g/vial or 5 g/vial treosulfan as a white, sterile, lyophilized powder in single-dose vials for reconstitution.

GRAFAPEX is contraindicated in patients with hypersensitivity to any component of the drug product.

Profound myelosuppression with pancytopenia is the desired therapeutic effect of GRAFAPEX-based preparative regimens, occurring in all patients. Time to neutrophil counts > 0.5 Gi/L occurred at a median of 18 days (range 7-42 days) after allogeneic hematopoietic stem cell transplantation in adult patients treated using GRAFAPEX in combination with fludarabine as the preparative regimen.

Do not begin the preparative regimen if the stem cell donor is not available. Monitor blood cell counts daily until hematopoetic recovery. Provide standard supportive care for infections, anemia and thrombocytopenia until there is adequate hematopoietic recovery.

There have been reports of seizures in patients following treatment with treosulfan. Monitor patients for signs of neurological adverse reactions. Clonazepam prophylaxis may be considered for patients at higher risk for seizures, including infants.

An increase of skin disorders (e.g. rash, dermatitis) was observed when patients received sodium bicarbonate-containing hydration in the course of treosulfan infusion, potentially because of acceleration of the pH‑dependent formation of alkylating epoxides [see Adverse Reactions ( 6.1) and Clinical Pharmacology ( 12.1)]. Keep skin clean and dry on days of GRAFAPEX infusion. Diaper dermatitis may occur because of excretion of treosulfan in the urine. Change diapers frequently during the 12 hours after each infusion of GRAFAPEX. Dermatitis may occur under occlusive dressings; change occlusive dressings after each infusion of GRAFAPEX.

GRAFAPEX may cause local tissue necrosis and injection site reactions, including erythema, pain, and swelling, in case of extravasation. Assure venous access patency prior to starting GRAFAPEX infusion, and monitor the intravenous infusion site for redness, swelling, pain, infection, and necrosis during and after administration of GRAFAPEX. If extravasation occurs, stop the infusion immediately and manage medically as required. Do not administer by the intramuscular or subcutaneous routes.

There is an increased risk of a secondary malignancy with use of GRAFAPEX. Treosulfan is carcinogenic and genotoxic [see Nonclinical Toxicology ( 13.1)] .  

The risk of secondary malignancy is increased in patients with Fanconi anemia and other DNA breakage disorders. The safety and efficacy of GRAFAPEX have not been established for patients with these disorders.

In MC‑FludT.14/L Trial I (NCT00822393), 330 adult patients were randomized to treosulfan at 14 g/m ²/day (1.4 times the recommended dose) for three consecutive days or busulfan at 3.2 mg/kg/day for two days, in combination with fludarabine as a preparative regimen for allogeneic transplantation. This trial was discontinued early due to a higher incidence of early fatal and/or serious adverse reactions in patients receiving treosulfan. Avoid exceeding the recommended GRAFAPEX dosage of 10 g/m ²daily for three consecutive days.

Based on its mechanism of action, GRAFAPEX can cause fetal harm when administered to a pregnant woman because it is genotoxic and affects dividing cells [see Clinical Pharmacology ( 12) and Nonclinical Toxicology ( 13)]. Advise pregnant women of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with GRAFAPEX and for 6 months following the last dose of GRAFAPEX. Advise males with female partners of reproductive potential to use effective contraception during treatment with GRAFAPEX and for 3 months after the last dose [see Use in Specific Populations ( 8.1) and ( 8.3)].

The following clinically significant adverse reactions are described elsewhere in the labeling:

• Myelosuppression [see Warnings and Precautions ( 5.1)]
• Seizures [see Warnings and Precautions ( 5.2)]
• Skin Disorders [see Warnings and Precautions ( 5.3)]
• Injection Site Reactions and Tissue Necrosis [see Warnings and Precautions ( 5.4)]
• Secondary Malignancies [see Warnings and Precautions ( 5.5)]

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

MC‑FludT.14/L Trial II

The safety of GRAFAPEX was evaluated in 553 adult patients with AML and MDS in a randomized trial (MC‑FludT.14/L Trial II) comparing GRAFAPEX in combination with fludarabine to busulfan in combination with fludarabine as a preparative regimen for allogeneic hematopoietic stem cell transplantation. The patients were randomized to receive GRAFAPEX (n=270) 10 g/m² daily on day -4, -3 and -2 or to busulfan (n=283) 0.8 mg/kg every 6 hours on day -4 and -3 in combination with fludarabine 30 mg/m ²daily on day -6, -5, -4, -3 and -2, and hematopoietic stem cell transplantation on day 0   [see Clinical Studies ( 14)] . 

Fatal regimen-related adverse reactions occurred within 30 days of transplantation in 1.9% of patients on the GRAFAPEX arm. All fatalities were due to pulmonary adverse reactions.

The most common adverse reactions (≥20%) in patients treated with GRAFAPEX were musculoskeletal pain, stomatitis, pyrexia, nausea, edema, infection, and vomiting. Selected Grade 3 or 4 nonhematological laboratory abnormalities were increased GGT, increased bilirubin, increased ALT, increased AST, and increased creatinine. 

Table 3 shows the adverse reactions in Study MC‑FludT.14/L Trial II through transplant Day +30.

Clinically relevant adverse reactions in <10% of patients who received GRAFAPEX included:

Neoplasms benign, malignant and unspecified (including cysts and polyps): second malignancy
Metabolism and nutrition disorders:
Decreased appetite, impaired glucose tolerance
Psychiatric disorders: Insomnia, confusional state, agitation
Nervous system disorders: Paresthesia, dizziness
Ear and labyrinth disorders: Vertigo
Cardiac disorders: Cardiac failure, pericardial effusion
Vascular disorders: Flushing, embolism, hypotension
Respiratory, thoracic and mediastinal disorders: Pneumonitis, pleural effusion, pharyngeal or laryngeal inflammation, dyspnea, cough, oropharyngeal pain, hiccups, dysphonia
Gastrointestinal disorders: Oral pain, gastritis, dyspepsia, dysphagia, abdominal distension, dry mouth
Skin and subcutaneous tissue disorders: Palmar plantar erythrodysesthesia syndrome, pruritus, erythema, dermatitis, skin hyperpigmentation, dry skin
Renal and urinary disorders: Acute kidney injury, hematuria, urinary tract pain
General disorders and administration site conditions: Chills, pain

Investigations: Weight decreased or increased, increase of C‑reactive protein

All patients treated with GRAFAPEX and fludarabine developed neutropenia, anemia, and thrombocytopenia. One patient on the GRAFAPEX arm had graft failure. Table 4 summarizes the selected nonhematological laboratory abnormalities in Study MC-FludT.14/L Trial II by treatment arm through Day +30 posttransplant.

The following additional adverse reactions have been identified during post approval use of GRAFAPEX in preparative regimens prior to hematopoietic stem cell transplantation in adult and pediatric patients in other countries. As these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Metabolism and Nutrition Disorders: Acidosis
Nervous system disorders: Peripheral sensory neuropathy
Renal and urinary disorders: Renal failure
Immune system disorders: Hypersensitivity

Certain CYP2C19 and CYP3A4 Substrates

Monitor for adverse reactions of certain CYP2C19 or CYP3A4 substrates where minimal concentration changes may lead to serious or life-threatening toxicities, and reduce the dosage, as needed, if recommended in the prescribing information of these substrates.

Treosulfan is a CYP2C19 and CYP3A4 inhibitor [see Clinical Pharmacology ( 12)] . Concomitant use of GRAFAPEX is predicted to increase the exposure of CYP2C19 and CYP3A4 substrates based on a mechanistic understanding of treosulfan metabolism, which may increase the risk of their adverse reactions.

Risk Summary

Based on its mechanism of action, GRAFAPEX can cause fetal harm when administered to a pregnant woman because it is genotoxic and affects dividing cells [see Clinical Pharmacology ( 12) and Nonclinical Toxicology ( 13)] . There are no available human clinical data on the use of treosulfan in pregnant women to support an estimation of a drug-associated risk. Specific embryo-fetal developmental toxicity studies with treosulfan in animals were not conducted. Advise pregnant women of the potential risk to a fetus [see Data].

In the U.S. general population, the estimated background risk of major birth defects is 2% – 4% and of miscarriage is 15% – 20% of clinically recognized pregnancies.

Data

Animal Data

Animal reproductive or developmental toxicity studies were not conducted with treosulfan. Treosulfan is genotoxic and is toxic to dividing cells, suggesting it can cause embryotoxicity and teratogenicity.

Risk Summary

There is no data on the presence of treosulfan or its metabolites in human milk, the effects on the breastfed child, or on milk production. Because of the potential for serious adverse reactions in breastfed children, advise women not to breastfeed during treatment with GRAFAPEX and for 1 week after the last dose.

Based on its mechanism of action, GRAFAPEX can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1)].

Pregnancy Testing

Conduct pregnancy testing in females of reproductive potential within 7 days prior to initiating therapy with GRAFAPEX.

Contraception

Females

Advise females of reproductive potential to use effective contraception during and up to 6 months after treatment with GRAFAPEX.

Males

Because of the potential for genotoxicity, advise males with female partners of reproductive potential to use effective contraception during treatment with GRAFAPEX and for 3 months after the last dose [see Nonclinical Toxicology ( 13.1)]

Infertility

Based on findings in animal studies, GRAFAPEX can impair fertility in females and males, and may cause temporary or permanent infertility [see Nonclinical Toxicology ( 13.1)] .

The safety and efficacy of GRAFAPEX as part of a preparative regimen prior to allogeneic hematopoietic stem cell transplant in pediatric patients 1 year of age and older with AML or MDS have been established based on evidence from an adequate and well-controlled study in adults, with additional pharmacokinetic and safety data in 111 pediatric patients, including 22 infants (1 month to < 2 years), 54 children (2 to < 12 years), and 35 adolescents (12 to < 17 years) [see Adverse Reactions ( 6.1), Clinical Pharmacology ( 12.3), and Clinical Studies ( 14)] . The incidence of hepatic and gastrointestinal adverse reactions was higher in pediatric patients than in adults.

Safety and effectiveness of GRAFAPEX as part of a preparative regimen prior to allogeneic hematopoietic stem cell transplant in pediatric patients with AML or MDS younger than 1 year of age have not been established.

Juvenile Animal Toxicity Data

Treatment of juvenile rats from postnatal day (PND) 10 to 35 with daily doses of 10, 50 or 100 mg/kg treosulfan (approximately 0.006, 0.03, 0.06-‑fold the human dose based on body surface area, BSA) generally resulted in findings comparable to those seen in adult animals. A delayed physical development indicated by decreased body weight, reduced relative organs weights, and delayed time point of vaginal opening were noted in the high-dosed rats. In a separate study, single intravenous administrations of 500 mg/kg treosulfan (0.3-‑fold the human dose based on BSA) to juvenile (PND 10) and young adult (PND 34 – 35) rats, treosulfan concentrations in brain tissue were low compared to plasma concentrations, but were approximately 2- to 3-fold higher in juvenile rats (4-6%) in comparison to young adults (2-3%).

Of the total number of GRAFAPEX-treated patients with AML or MDS in Study MC-FludT.14/L Trial II (n=270), 73 (27%) were 65 to 74 years of age, and none were 75 years of age and older [see Clinical Studies ( 14)] . No significant differences in safety or effectiveness were observed between these subjects and younger subjects.

The principal toxic effect of treosulfan in cases of overdose are myeloablation and prolonged pancytopenia, mucositis, skin toxicity, nausea, vomiting and gastritis. In case of overdosage, monitor blood counts frequently and provide vigorous supportive measures as medically indicated.

GRAFAPEX for injection contains treosulfan, an alkylating drug. Treosulfan is known chemically as L-‑threitol ‑1,4-‑dimethanesulfonate. Treosulfan is soluble in water (7% m/v) at 25ᴼC. Treosulfan is not hygroscopic.Treosulfan has the molecular formula C ₆H ₁₄O ₈S ₂and a molecular weight of 278.3 g/mole. Treosulfan has the following chemical structure:

Treosulfan Chemical Structure (Chemical Structure)

GRAFAPEX is intended for intravenous administration. It is supplied as a white, sterile, lyophilized powder for injection in glass vials containing 1 g or 5 g treosulfan.

Treosulfan is an alkylating agent. DNA alkylation is thought to be responsible for the cytotoxic activities of treosulfan. Treosulfan showed hematopoietic stem cell depleting activity as well as immunosuppressive and antitumor activity in mouse models of leukemia.

Increase in treosulfan exposure was associated with an increased incidence of infection-related death. Treosulfan time course of pharmacodynamic response is unknown.

Treosulfan pharmacokinetic parameters were observed at the approved recommended dosage, unless otherwise specified.

Treosulfan is a prodrug. Treosulfan mean ± SD area under the curve (AUC) is 1,200 ± 211 hr mcg/mL. There was no dose accumulation.

Distribution

Treosulfan mean (CV%) volume of distribution is approximately 41 liters (CV%: 19%). Treosulfan does not bind to plasma albumin.

Elimination

Treosulfan mean (± standard deviation) terminal half-life is 1.7 ± 0.4 hours.

Metabolism

The pharmacologically inactive treosulfan is converted spontaneously under physiological conditions into the active monoepoxide intermediate (2S,3S)‑1,2‑epoxybutane‑3,4‑diol‑4‑methanesulfonate) and finally to active L‑diepoxibutane (2S,3S)‑1,2:3,4‑diepoxybutane).

Excretion

A median of 42% of the treosulfan dose is excreted unchanged in the urine within 24 hours, and 89% of this unchanged fraction is excreted within the first 8 hours after administration.

Specific Populations

No clinically significant differences in the pharmacokinetics of treosulfan based on sex, mild renal impairment (CLcr 60‑89 mL/min), or mild hepatic impairment (total bilirubin less than or equal to ULN with AST greater than ULN or total bilirubin greater than 1 to 1.5 times ULN with any AST). The effect of moderate or severe renal impairment, moderate or severe hepatic impairment, and age ≥ 65 years on treosulfan pharmacokinetics is unknown.

Pediatric Patients

Treosulfan exposure in pediatric patients with BSA < 0.7 m ²and with BSA 0.7 to < 1.1 m ²are 11% and 5% higher, respectively, compared to adults.

No clinically significant difference in treosulfan median terminal half‑life was observed between pediatric patients and adults. The median terminal half‑life of the active monoepoxide intermediate was 1.6 hrs in pediatric patients.

Drug Interaction Studies

In Vitro Studies

CYP Enzymes:Treosulfan is a CYP2D6 substrate and its monoepoxide intermediate is a CYP2C8 substrate. Treosulfan inhibits CYP2C19 and CYP3A4 (using midazolam as substrate), but does not inhibit CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2D6, or CYP3A4 (using testosterone as substrate).

Transporter Systems: Treosulfan does not inhibit BCRP, BSEP, MATE1, OATP1B1, OATP1B3, OAT1, OAT3, OCT1, or OCT2.

Carcinogenesis and Mutagenesis

No carcinogenicity study has been conducted. Treosulfan was mutagenic in the in vitro bacterial mutagenicity assay (Ames test) and clastogenic in the in vitro micronucleus assay in human lymphocytes.

No dedicated animal fertility studies were conducted. In a general toxicity study in rats, animals were treated with 5 or 50 mg/kg/day treosulfan orally for 7 months, 6 days a week. Spermatogenesis and ovarian function were significantly affected, starting at 5 mg/kg (0.003‑fold the human dose based on BSA). Findings included reduced weight of the testicles, seminal vesicle, prostate, and uterus, as well as spermatogenesis reduction and arrest, uterine atrophy, and reduced or absent corpora lutea and follicles. 

The efficacy of GRAFAPEX was evaluated in a randomized active-controlled trial (MC‑FludT.14/L Trial II; NCT00822393) comparing GRAFAPEX to busulfan in combination with fludarabine as a preparative regimen for allogeneic transplantation. Eligible patients included adults 18 to 70 years old with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS), Karnofsky performance status > 60%, and age ≥ 50 years or hematopoietic cell transplantation comorbidity index [HCT‑CI] score > 2. Patients were excluded if the creatinine clearance was < 60 mL/min, forced expiratory volume (FEV1) < 50% or on supplemental oxygen, left ventricular ejection fraction (LVEF) < 40%, bilirubin > 3X ULN, or aminotransferases (ALT or AST) > 5X ULN.

The patients were randomized to receive GRAFAPEX 10 g/m² daily on day -4, -3 and -2 or to busulfan 0.8 mg/kg every 6 hours on day -4 and -3 in combination with fludarabine 30 mg/m ²daily on day -6, -5, -4, -3 and -2, and hematopoietic stem cell transplantation on day 0. For the subset of patients with unrelated donors, antithymocyte globulin was administered in 97% and 95% of patients on each arm, respectively. Cyclosporine and methotrexate was used as graft‑vs‑host disease prophylaxis.

There were 570 patients randomized to GRAFAPEX (n = 280) or busulfan (n = 290). The efficacy population included 365 patients with AML and 205 patients with MDS: 536 patients received peripheral blood stem cells, 15 patients received marrow stem cells, and 19 patients were not transplanted. Table 5 shows the baseline characteristics of the study patients. 

Efficacy was established on the basis of overall survival (OS), defined as the time from randomization until death from any cause. The hazard ratio (HR) for OS (stratified by donor type and risk group) compared to busulfan was 0.67 (95% CI: 0.51, 0.90) in the randomized population, 0.73 (95% CI: 0.51, 1.06) in patients with AML, and 0.64 (95% CI: 0.40, 1.02) in patients with MDS. Results are displayed in Figures 1, 2, and 3 below.
