Use is contraindicated in patients with known allergy to dimethyl sulfoxide (DMSO), Dextran 40, gentamicin, human serum albumin, or bovine material [see Contraindications (4), Warnings and Precautions (5.2)].
• Autoimmune cytopenias: Autoimmune cytopenias have occurred following treatment of severe aplastic anemia. Monitor blood counts prior to and after infusion. Manage cytopenias according to local institutional guidelines [see Warnings and Precautions (5.3)].
• Graft failure: Graft failure may be fatal. Monitor patients for laboratory evidence of hematopoietic recovery [see Warnings and Precautions (5.4)].
• Engraftment syndrome: Engraftment syndrome may be fatal. Treat engraftment syndrome promptly with corticosteroids [see Warnings and Precautions (5.6)].

OMISIRGE is indicated for the treatment of adults and pediatric patients 12 years and older with hematologic malignancies who are planned for umbilical cord blood transplantation following myeloablative conditioning to reduce the time to neutrophil recovery and the incidence of infections.

OMISIRGE is indicated for the treatment of adults and pediatric patients 6 years of age and older with severe aplastic anemia (SAA) following reduced intensity conditioning.

For intravenous use only.

The recommended dose of OMISIRGE is a one-time infusion delivered in two separate bags which consists of

• a Cultured Fraction (CF): a minimum of 8.0 × 10⁸ total viable cells of which a minimum of 8.7% is CD34+ cells and a minimum of 9.2 × 10⁷ CD34+ cells, and
• a Non-cultured Fraction (NF): a minimum of 4.0 × 10⁸ total viable cells with a minimum of 2.4 × 10⁷ CD3+ cells

The CF and NF are supplied cryopreserved. OMISIRGE requires thaw and dilution with two infusion solution (IS) bags (one IS bag for the CF, and one IS bag for the NF) prior to administration. Infusion of the NF bag should begin within 1 hour after completion of the CF infusion. For timing of dosing of each fraction, refer to section 2.2 under "Planning prior to OMISIRGE preparation".

Administration of OMISIRGE should be under the supervision of a physician experienced in treatment of hematologic malignancies or SAA, as appropriate, in centers with expertise in hematopoietic stem cell transplants.

Preparation

Pretreatment

• Confirm the Release For Infusion Certificate (RFI Certificate) is available for OMISIRGE before starting the conditioning regimen.
• Before infusion of OMISIRGE, administer as appropriate:
  • For patients with hematologic malignancies, administer a myeloablative conditioning regimen according to institutional guidelines.
  • For patients with SAA, administer a reduced intensity conditioning regimen according to institutional guidelines.

  Planning prior to OMISIRGE preparation

  • OMISIRGE must not be prepared until after receipt of the RFI Certificate for this patient-specific batch of OMISIRGE. CoAs for the CF, NF and IS batches are attached to the RFI Certificate. The RFI certificate will be issued via Gamida Cell Assist Hospital Portal up to 72 hours after completion of manufacturing.
  • Confirm receipt of the RFI Certificate. Confirm patient-specific identifiers on the RFI Certificate and CoAs match the patient's identity.
  • The CF bag must be administered FIRST.
  • Confirm the infusion time in advance and adjust the start time of CF cryopreserved bag thaw so that it will be available for infusion when the patient is ready.
  • Once the CF cryopreserved bag is removed from the metal cassette, thawing and dilution must be carried to completion and the cells administered within 2 hours post-dilution.
  • Do not thaw the NF cryopreserved bag until you have determined that the CF has been safely administered.
  • Once the NF cryopreserved bag is removed from the metal cassette, thawing and dilution must be carried to completion and the cells administered within 1 hour post-dilution.
  • The infusion of the NF bag should begin within 1 hour after completion of the CF infusion.

  Preparation of OMISIRGE for Infusion

  • Follow universal precautions and local biosafety guidelines for handling and disposal of human cells to avoid potential transmission of infectious diseases.
  • Use aseptic technique for all processing steps, including spiking of all transfusion infusion bag ports. No samples should be drawn from OMISIRGE.

  The Cultured Fraction

  Preparation of the Infusion Solution for CF

  • 1.Remove the IS for CF bag from the 2-8°C storage location. Remove only the IS for CF bag at this time.
  • 2.Confirm patient-specific identifiers on the label of the IS for CF match the intended patient.
  • 3.Wipe the IS for CF sterile bag with 70% alcohol. Place it in the Biological Safety Cabinet (BSC) (if available), for at least 20 minutes with a maximum of 24 hours at room temperature.
  • 4.Prior to dilution, remove the IS for CF bag from its sterile bag. Check that the pinch clamp is closed.

  Thawing and diluting the CF

  • 5.Remove the CF metal cassette from the liquid nitrogen storage.
  • 6.Prior to preparing the bag for infusion verify that the patient-specific identifiers on the label on the outside of the cassette and on the CF cryopreserved bag match the intended patient (see Figure 1).
  • 7.

    Once patient identity has been verified, remove the CF cryopreserved bag from the cassette. Leave the CF cryopreserved bag in the overwrap bag during thawing and dilution.

  • 8.Visually inspect the CF cryopreserved bag for damage. If the bag is damaged, contact Gamida Cell at (844) 477-7478. The cryopreserved CF should be white in color.
  • 9.Once the CF cryopreserved bag is removed from the metal cassette, the thaw and dilution must be carried to completion and the cells administered within 2 hours post-dilution.
  • 10.Incubate the CF cryopreserved bag for 5 minutes at room temperature.
  • 11.Place the CF cryopreserved bag in an approximately 37°C water bath until the product reaches a liquid consistency. This generally takes about 3-8 minutes.

  Do not massage, knead or apply pressure on the product bag. Keep the bag fully submerged until thawed – do not remove before thawing completion.

  • 12.Remove the thawed bag from the water bath as soon as the cells have completely thawed. Do not remove the overwrap bag.
  • 13.Wipe the overwrap with 70% alcohol. Put the bag into the BSC (if available).
  • 14.Open the overwrap as follows:
    • –Wipe a pair of clean scissors with 70% alcohol.
    • –Cut the sealed area at the top of the overwrap.
      Be careful not to damage the CF bag or the CF bag's ports/ tubing.
    • 15.Insert the spike adapter attached to the IS for CF bag into one of the ports of the CF bag, while it remains in the overwrap bag.
    • 16.Open the pinch clamp on the IS tubing and double the volume of the CF by adding IS for CF (approximately 20 mL) to the CF bag. Gently swirl the bag until mixed well.
    • 17.Add the remaining IS for CF (approximately 60 mL) to the CF bag. Close the valve and swirl gently.
    • 18.Remove the overwrap of the CF bag and check the integrity of the CF bag.
    • 19.Check the appearance of the contents of the CF bag. The thawed and diluted CF should appear as a yellowish suspension, essentially free of visible white clumps and foreign particulates.
    • 20.Inspect the contents of the thawed and diluted CF bag for any visible cell clumps. If visible cell clumps remain, gently invert and/or massage the bag with fingertips. Small clumps of cellular material should disperse with gentle manual mixing. Do not infuse the CF if clumps are not dispersed, the bag is damaged or leaking, or otherwise appears to be compromised. If this occurs, call Gamida Cell at (844) 477-7478.
    • 21.Heat seal and detach the emptied Infusion Solution for CF bag.
    • 22.Connect the Transfusion Infusion Set to the free port on the CF bag. Alternatively, the infusion set may be connected in accordance with internal procedures.
    • 23.Place the CF bag containing the thawed and diluted CF in a new sterile bag.

    Note: Do not wash, spin down, and/or resuspend CF in new media prior to infusion.

    • 24.Transport the product to the patient at room temperature. Unless prepared at the patient's bedside, transport the product to the bedside in a closed box/bag to protect the product during transport.
      The CF bag should be completely infused within 2 hours post-dilution.
    • 25.See the ‘Administration’ section on how to infuse the CF.

    Administration

    Do NOT use a leukodepleting filter

    • Central venous access is recommended for the infusion of OMISIRGE.
    • Confirm that the patient's identity matches the patient-specific identifiers on the CF and NF bags.
    • Administer OMISIRGE by gravity infusion.
    • Prior to spiking both the CF and NF bags, prime the infusion set tubing with normal saline.
    • Infuse the entire contents of the CF and NF bags.
    • The rate of infusion should not exceed a maximum of 10 mL per kg per hour.

    Administration:

    • The thawed and diluted CF bag must be infused FIRST. The infusion time should not exceed 2 hours from the end of dilution to the end of CF infusion. Should an infusion reaction occur, appropriately manage the reaction before thawing the NF.
    • The thawed and diluted NF should be infused within 1 hour of safely administering the CF infusion. The infusion time should not exceed 1 hour from the end of dilution to the end of infusion.
    • In the event of any deviation from the dosing schedule, contact Gamida Cell at (844) 477-7478.
    • After the entire contents of the CF and NF bags are each infused, wash the tubing with normal saline at the same infusion rate to ensure as many cells as possible are delivered to the patient.

    Follow universal precautions and local biosafety guidelines for handling and disposal of human cells to avoid potential transmission of infectious diseases.

    Monitoring

    • Monitor the patient for hypersensitivity or other infusion-related reactions during the infusion and post-infusion, per institutional guidelines.
    • Reduce the infusion rate if the fluid load is not tolerated. Pause the infusion in the event of a hypersensitivity reaction or if the patient develops a moderate to severe infusion reaction. Administer appropriate medical therapy as needed. [See Warnings and Precautions (5.2)]
    • Conduct frequent clinical and laboratory assessments and vital signs and monitor for graft failure, GvHD, infections and other post-transplant complications according to institutional guidelines.

    Hematologic Malignancies

    The safety of OMISIRGE is based on data from Study P0501 for 52 patients transplanted with OMISIRGE and 56 patients transplanted with umbilical cord blood (UCB) [see Clinical Studies (14)]. The median duration of follow up for the overall safety population was 14 months (range, 1-19 months). All patients received myeloablative preparative regimens and GvHD prophylaxis with tacrolimus or cyclosporin plus mycophenolate mofetil.

    Fatal adverse reactions occurred in 17% of patients treated with OMISIRGE, including infection (6%), acute GvHD (6%), veno-occlusive disease (VOD)/sinusoidal obstruction syndrome (SOS) (2%), thrombotic thrombocytopenic purpura (TTP)/thrombotic microangiopathy (TMA) (2%), and pulmonary hemorrhage (2%). Fatal adverse reactions occurred in 29% of subjects treated with UCB, including infection/sepsis (11%), respiratory disorders (11%), GvHD (5%), and VOD/SOS (2%).

    The most common non-laboratory adverse reactions occurring in ≥ 10% of patients in Study P0501 are listed in Table 2 below. The most common Grade 3-5 adverse reactions for patients treated with OMISIRGE, were pain (33%), mucosal inflammation (31%), hypertension (25%), and gastrointestinal toxicity (19%).

    Risk Summary

    There are no available data with OMISIRGE use in pregnant women. No animal reproductive and developmental toxicity studies have been conducted with OMISIRGE to assess whether it can cause fetal harm when administered to a pregnant woman. In Study 17-H-0091, one patient reported two pregnancies, one at 9 months and one at 3.5 years post-transplant. There were no reported birth complications or neonatal concerns.

    OMISIRGE should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

    In the United States (U.S.) general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

    Risk Summary

    There is no information regarding the presence of OMISIRGE in human milk, the effect on the breastfed infant, and the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for OMISIRGE and any potential adverse effects on the breastfed infant from OMISIRGE or from the underlying maternal condition.

    Pregnancy Testing

    Pregnancy status of females with reproductive potential should be verified. Sexually active females of reproductive potential should have a pregnancy test prior to starting the conditioning regimen for OMISIRGE.

    Contraception

    See the prescribing information for the medications used for conditioning for information on the need for effective contraception in patients who receive a conditioning regimen.

    There are insufficient exposure data to provide a recommendation concerning duration of contraception following treatment with OMISIRGE.

    Infertility

    There are no data on the effect of OMISIRGE on fertility.

    Per Protocol Population:

    Among the patients treated with OMISIRGE (n=52), neutrophil recovery with 42 days of follow-up was achieved in 94% of patients at a median of 10 days (95% CI: 8, 12), compared to 89% of patients treated with UCB (n=56), at a median of 20 days (95% CI: 18, 24). BMT CTN Grade 2/3 bacterial or Grade 3 fungal infections by 100 days were reported in 35% of patients treated with OMISIRGE and 61% of patients treated with UCB, respectively.

    The Cryopreserved Cell Fractions

    OMISIRGE is comprised of two cryopreserved cell fractions, a Cultured Fraction (CF) and a Non-cultured Fraction (NF) each in a separate cryopreserved bag labeled for the specific patient. Each cryopreserved bag is protected by a corresponding transparent overwrap bag and each cryopreserved bag enclosed in its overwrap bag is individually packed in a metal cassette. Both cryopreserved OMISIRGE cell fractions are shipped together in the vapor phase of liquid nitrogen in a liquid nitrogen dry vapor shipper with the Prescribing Information (PI) and a Chimerism Testing Sample(s).

    At the time of cryopreservation, the CF contains a minimum of 8.0 × 10⁸ total viable cells with a minimum of 8.7% CD34+ cells and a minimum of 9.2 × 10⁷ CD34+ cells suspended in 20 mL of a cryopreservation solution containing 10% DMSO.

    See the CoA for the CF for actual cell counts. CoAs are attached to the RFI Certificate available via the Gamida Cell Assist Hospital Portal.

    Upon cryopreservation, the CF appears white and is frozen at the bottom of the cryopreserved bag.

    At the time of cryopreservation, the NF contains a minimum of 4.0 × 10⁸ total viable cells with a minimum of 2.4 × 10⁷ CD3+ cells suspended in 10 mL cryopreservation solution containing 10% DMSO.

    See the CoA for the NF for actual cell counts.

    Upon cryopreservation, the NF appears red and is frozen at the bottom of the cryopreserved bag.

    • Match the identity of the patient with the patient-specific identifiers on the cassettes and cryopreserved bag labels upon receipt.
    • Store OMISIRGE frozen in the vapor phase of liquid nitrogen (≤ -150°C) in a temperature-controlled system.
    • Thaw immediately prior to use [see Dosage and Administration (2.2)].
    • Use closed containers when transporting the bags within the facility.

A single dose of OMISIRGE consists of:

• a Cultured Fraction: At the time of cryopreservation, the CF contains a minimum of 8.0 × 10⁸ total viable cells with a minimum of 8.7% CD34+ cells and a minimum of 9.2 × 10⁷ CD34+ cells suspended in approximately 10% dimethyl sulfoxide (DMSO).
• a Non-cultured Fraction: At the time of cryopreservation, the NF contains a minimum of 4.0 × 10⁸ total viable cells with a minimum of 2.4 × 10⁷ CD3+ cells suspended in approximately 10% DMSO.

Each fraction is supplied separately in its own cryopreserved bag [see How Supplied/Storage and Handling (16)]. Both bags diluted with their respective IS must be infused to achieve the dose of OMISIRGE.

See the respective CoA for the CF and NF for actual cell counts. The CoAs are attached to the RFI Certificate available via the Gamida Cell Assist Hospital Portal.

Table 1: Appearance of OMISIRGE

Product Bags	Appearance Immediately before Thawing	Appearance Post-Dilution
Cultured Fraction	White, frozen at the bottom of the cryopreserved bag	Yellowish suspension, essentially free of visible white clumps and foreign particulates
Non-cultured Fraction	Red, frozen at the bottom of the cryopreserved bag	Reddish suspension, essentially free of visible clumps and foreign particulates

OMISIRGE is contraindicated in patients with known hypersensitivity to dimethyl sulfoxide (DMSO), Dextran 40, gentamicin, human serum albumin, or bovine products.

Acute and chronic graft-versus-host disease (GvHD) have occurred following treatment with OMISIRGE [see Adverse Reactions (6.1)]. Acute GvHD manifests as maculopapular rash, gastrointestinal symptoms, and elevated bilirubin. Chronic GvHD manifests as skin rash, oral symptoms, ocular dryness, transaminase elevations, gastrointestinal symptoms, or serositis.

Patients treated with OMISIRGE should receive immunosuppressive drugs to decrease the risk of GvHD, and be monitored for signs and symptoms of GvHD, and treated if GvHD develops.

Hypersensitivity and infusion-related reactions have occurred with OMISIRGE administration [see Adverse Reactions (6.1)].

Serious hypersensitivity reactions, including anaphylaxis, may be due to DMSO, residual gentamicin, Dextran 40, human serum albumin (HSA) and bovine material in OMISIRGE. OMISIRGE may contain residual antibiotics if the cord blood donor was exposed to antibiotics in utero. Patients with a history of allergic reactions to antibiotics should be monitored for allergic reactions following OMISIRGE administration.

Signs and symptoms of hypersensitivity reactions may include bronchospasm, wheezing, angioedema, pruritus, hives, fever, and hypotension during or after OMISIRGE infusion.

Infusion-related reactions may begin within minutes of the start of infusion of OMISIRGE, although symptoms may continue to intensify and not peak for several hours after the completion of the infusion.

Premedicate patients with antipyretics, histamine antagonists, and corticosteroids and monitor closely for signs and symptoms of hypersensitivity and infusion-related reactions. When a reaction occurs, pause the infusion and institute supportive care as needed.

Autoimmune cytopenias (AICs) have occurred with OMISIRGE administration in patients with SAA. AIC is characterized by thrombocytopenia, anemia, and neutropenia, alone or in combination, occurring weeks to months post-transplant, often after initial hematopoietic recovery.

Risk factors for post-transplant AIC include younger age, ATG-containing conditioning, underlying SAA, and delayed T cell chimerism.

Monitor blood counts prior to and after OMISIRGE infusion. Manage cytopenias according to local institutional guidelines.

Graft failure has occurred with OMISIRGE administration [see Adverse Reactions (6.1)]. Primary graft failure, which may be fatal, is defined as failure to achieve an absolute neutrophil count greater than 500 per microliter blood by Day 42 after transplantation. Immunologic rejection is the primary cause of graft failure. Patients should be monitored for laboratory evidence of hematopoietic recovery.

Malignancy of donor origin including post-transplant lymphoproliferative disorder (PTLD) has occurred with OMISIRGE administration. PTLD manifests as a lymphoma-like disease favoring non-nodal sites. PTLD is usually fatal if not treated. The etiology is thought to be donor lymphoid cells transformed by Epstein-Barr virus (EBV). Serial monitoring of blood for EBV DNA may be warranted in patients with persistent cytopenias.

A donor-cell derived myelodysplastic syndrome (MDS) has occurred with OMISIRGE administration. The natural history is presumed to be the same as that for de novo MDS. Monitor life-long for secondary malignancies.

In the event that a secondary malignancy occurs, contact Gamida Cell at (844) 477-7478.

Engraftment syndrome may occur because OMISIRGE is derived from umbilical cord blood. Monitor patients for unexplained fever, rash, hypoxemia, weight gain, and pulmonary infiltrates in the peri-engraftment period. Treat with corticosteroids as soon as engraftment syndrome is recognized to ameliorate symptoms. If untreated, engraftment syndrome may progress to multiorgan failure and death.

Transmission of infectious disease may occur because OMISIRGE is derived from umbilical cord blood. Disease may be caused by known or unknown infectious agents. Donors are screened for increased risk of infection with human immunodeficiency virus (HIV), human T-cell lymphotropic virus (HTLV), hepatitis B virus (HBV), hepatitis C virus (HCV), T. pallidum, West Nile virus (WNV), transmissible spongiform encephalopathy (TSE) agents, vaccinia, and Zika virus [for umbilical cord blood (UCB) collected between March 2016 and 20 May 2024]. Donors are also screened for clinical evidence of sepsis, and communicable disease risks associated with xenotransplantation. Maternal blood samples are tested for HIV types 1 and 2, HTLV types I and II, HBV, HCV, T. pallidum, and WNV. OMISIRGE is tested for sterility. There may be an effect on the reliability of the sterility test results if the cord blood donor was exposed to antibiotics in utero. OMISIRGE is tested for sterility, endotoxin, and mycoplasma. These measures do not totally eliminate the risk of transmitting these or other transmissible infectious diseases and disease agents.

Testing of maternal and infant donor blood is also performed for evidence of donor infection due to cytomegalovirus (CMV).

Test results may be found on the container label and/or in accompanying records.

Product manufacturing includes bovine-derived reagents. While all animal-derived reagents are tested for animal viruses, bacteria, fungi, and mycoplasma before use, these measures do not eliminate the risk of transmitting these or other transmissible infectious diseases and disease agents.

Final sterility test results may not be available at the time of use, but Quality Assurance (QA) will communicate any positive results from sterility testing to the physician. Report the occurrence of transmitted infection to Gamida Cell at (844) 477-7478.

OMISIRGE may transmit rare genetic diseases involving the hematopoietic system because it is derived from umbilical cord blood. Cord blood donors have been screened to exclude donors with sickle cell anemia, and anemias due to abnormalities in hemoglobins C, D, and E. Because of the age of the donor at the time cord blood collection takes place, the ability to exclude rare genetic diseases is severely limited. Report the occurrence of transmitted rare genetic disease to Gamida Cell at (844) 477-7478.

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.

The safety and efficacy of OMISIRGE have been established in pediatric patients with hematologic malignancy 12 years of age and older and in pediatric patients with severe aplastic anemia (SAA) 6 years of age and older.

The use of OMISIRGE in pediatric patients with hematologic malignancy was supported by evidence from one clinical study (Study P0501) which included 2 pediatric patients age 12 to 16 years. The use of OMISIRGE in pediatric patients with SAA was supported by evidence from one clinical study (Study 17-H-0091) which included 7 pediatric patients 6 to 16 years of age.

Clinical studies of OMISIRGE did not include patients aged 65 and over; therefore, it cannot be determined whether patients 65 years and over respond differently from younger patients.

OMISIRGE (omidubicel-onlv) is a cryopreserved nicotinamide modified unrelated allogeneic hematopoietic progenitor cell therapy derived from cord blood consisting of 2 cell fractions; a Cultured Fraction (CF) and a Non-cultured Fraction (NF) which are both derived from the same patient-specific cord blood unit (CBU).

1) The CF is a yellowish suspension consisting of allogeneic, hematopoietic CD34+ progenitor cells.

In addition to the CD34+ hematopoietic progenitor cells (HPCs), the CF consists of other cell populations, including more differentiated myelomonocytic cells, dendritic cells and granulocytes. The CF formulation contains a maximum of 35 mg gentamicin. Following manipulation, the cells are washed, formulated into a suspension, and cryopreserved in a patient specific bag in 10% dimethyl sulfoxide (DMSO). The product is thawed and diluted prior to infusion [see Dosage and Administration (2.2), How Supplied/Storage and Handling (16)]. The CF contains approximately 2.42 mg of DMSO. The diluted CF contains ≤ 2% DMSO.

2) The NF is a reddish suspension consisting of allogeneic, hematopoietic mature myeloid and lymphoid cells that are washed, formulated into a suspension, and cryopreserved in a patient specific bag in 10% DMSO. In addition to the mature myeloid and lymphoid cells, the NF consists of other cell populations, including more lineage committed hematopoietic cells. The product is thawed and diluted prior to infusion [see Dosage and Administration (2.2), How Supplied/Storage and Handling (16)]. The NF contains approximately 1.1 mg of DMSO. The diluted NF contains ≤2% DMSO.

Two Infusion Solution bags are also provided for diluting each fraction after thawing, one specifically for the CF and one specifically for the NF. The Infusion Solutions contain 8% w/v HSA and 6.8% w/v Dextran 40 in 0.9% sodium chloride [see Dosage and Administration (2.2)].

The NF and IS are Released for Shipment (RFS) following full release testing, including sterility test. The CF is RFS at the end of manufacturing, prior to final product testing completion. OMISIRGE is Released for Infusion (RFI) after acceptable results from the CF's Rapid Contamination Test for microbial contamination and quantitative PCR-based mycoplasma test are obtained. The RFI includes all CF DP release testing as detailed in the CF CoA, except the pending Colony Forming Unit (CFU) and final Sterility tests results. RFI certificate is accompanied with the respective IS, NF, and CF CoA's. Receipt of the RFI Certificate for the patient-specific batch of OMISIRGE must be confirmed prior to preparation. RFI Certificate receipt is via the Gamida Cell Assist Hospital Portal, approximately 72 h of the end of manufacturing.

OMISIRGE is a nicotinamide (NAM) modified allogeneic hematopoietic progenitor cell therapy derived from cord blood used as an allogeneic stem cell donor source. OMISIRGE is manufactured utilizing a proprietary NAM based technology producing enriched HPCs.

NAM technology overcomes the induction of accelerated proliferation, differentiation, cellular stress and signaling pathways that are typically activated when HPCs are removed from their natural environment.

Ex-vivo culturing of cord blood derived HPCs in the presence of NAM leads to preservation of their stemness, homing to the bone marrow (BM) and retained engraftment capacity as demonstrated by rapid neutrophil engraftment and multi lineage immune reconstitution as observed in the clinical trials with OMISIRGE.

Transplantation with OMISIRGE resulted in rapid and broad immune reconstitution of dendritic cells, monocytes, Natural Killer (NK), CD4+ T cells and CD8+ T cells as early as one-week post-transplantation, and B cells 28 days post transplantation and all lineages throughout the one-year follow-up period. Robust positive linear correlations between the CD34(+) cell content in the OMISIRGE CF, and the reconstitution of T-cells and NK cells were identified. Additionally, dose-response analyses demonstrated a strong correlation between the total CD34+ cell counts and dose / kg for OMISIRGE with the kinetics of neutrophil recovery. The model demonstrated that days to neutrophil recovery decreased with an increase in OMISIRGE CD34(+) cell dose.

OMISIRGE is a cryopreserved nicotinamide modified allogeneic hematopoietic progenitor cell therapy derived from cord blood. The nature of OMISIRGE is such that conventional pharmacokinetic studies on absorption, distribution, metabolism, and excretion are not applicable.

No in vivo carcinogenicity, mutagenicity and fertility studies were conducted to evaluate the effects of OMISIRGE.

OMISIRGE was evaluated in Study P0501 (NCT02730299), an open-label, multicenter, randomized study of OMISIRGE transplantation or UCB transplantation following myeloablative conditioning in patients with hematologic malignancies.

In total, 125 patients with the availability of at least one ≥ 4/6 human leukocyte antigen (HLA)-matched (HLA-A, B and DR loci) cord blood unit were randomized to the study, 62 patients were randomized to receive OMISIRGE and 63 patients were randomized to the UCB group. The minimum specifications of OMISIRGE were a Total Nucleated Viable Cell (TNVC) count of 8.0 × 10⁸ cells and CD34+ cell count of 5.6 × 10⁷. Fifty-two patients were transplanted with OMISIRGE at a median CD34+ cell dose of 9.0 × 10⁶ cells/kg (range 2.1 – 47.6 × 10⁶ cells/kg). Fifty-six patients were transplanted in the UCB arm with one or two cord units (66% received two cord units); among patients in whom the post-thaw cell dose was reported (n = 42), the median CD34+ cell dose was 0.2 × 10⁶ cells/kg (range 0.0 – 0.8 × 10⁶ cells/kg). Multiple conditioning regimens were used, including Total Body Irradiation (TBI)-based or chemotherapy-based options.

Demographic and baseline patient characteristics were similarly distributed among the treatment arms. The overall study population included 72 males (58%) and 53 females (42%) with median age 41 years (range: 13–65). Fifty-eight percent of patients were White, 16% were Black, 14% were Asian and 13% were of other races or unknown. Thirteen percent of patients identified as Hispanic or Latino. Forty-eight percent of patients had Acute Myelogenous Leukemia (AML), 33% had Acute Lymphoblastic Leukemia (ALL), 7% had Myelodysplastic Syndrome (MDS), 5% had Chronic myeloid leukemia (CML), 4% had lymphoma and 3% had other rare leukemias. Baseline disease status (remission vs. overt disease) varied depending on the hematologic malignancy. Disease risk index was high/very high for 34% and moderate for 42%. HCT specific comorbidity index was ≥ 3 in 51% and 1-2 in 28% of patients.

Of the patients randomized to OMISIRGE, 8% of patients (5/62) were not able to receive OMISIRGE due to manufacturing failure.

The efficacy of OMISIRGE was established based on time to neutrophil recovery following transplantation and the incidence of BMT CTN Grade 2/3 bacterial or Grade 3 fungal infections through Day 100 following transplantation. The efficacy outcomes are summarized below.

Eighty-seven percent of patients in the OMISIRGE arm and 83% in the UCB arm achieved neutrophil recovery. The median time to neutrophil recovery was 12 days in the OMISIRGE arm and 22 days in the UCB arm. BMT CTN Grade 2/3 bacterial or Grade 3 fungal infections through Day 100 following transplantation occurred in 39% of patients in the OMISIRGE arm and 60% of patients in the UCB arm.

The efficacy of OMISIRGE in patients with severe aplastic anemia (SAA) was evaluated in study 17- H-0091 (NCT 03173937), an open-label, single center study. The study enrolled patients with SAA who had intolerance or failure to respond to immunosuppressive therapy and availability of at least one ≥ 4/8 human leukocyte antigen (HLA)-matched (HLA-A, B, C and DR loci) cord blood unit. Patients were excluded if there was availability of an HLA identical (12/12) matched related or unrelated donor.

In total, 17 patients were treated with OMISIRGE, among them 14 patients were treated with OMISIRGE alone and three patients were treated with both OMISIRGE and haploidentical CD34+ cells. The minimum specifications of OMISIRGE were a Total Nucleated Viable Cell (TNVC) count of 8.0 × 10⁸ cells and CD34+ cell count of 9.2 × 10⁷. The fourteen patients who were transplanted with OMISIRGE alone were included in the efficacy evaluation. The median CD34+ cell dose of OMISIRGE was 9.5 × 10⁶ cells/kg (range, 2.3 - 21.4 cells/kg). All patients received reduced intensity conditioning which included cyclophosphamide, fludarabine, TBI and horse-ATG. GvHD prophylaxis was administered according to institutional guidelines.

The demographic characteristic of the population included the following: median age was 17 years (range: 6 – 45), 10 patients (59%) were male, 6 patients (35%) were Black, 3 patients (18%) were White, 5 patients (29%) were Asian and 3 patients (18%) were of "other races" or "unknown". Twenty-nine percent of patients identified as Hispanic or Latino. Median absolute neutrophil count at baseline was 0.3 × 10⁹/L (range, 0.0 – 1.0) and median platelet count at baseline was 35 × 10⁹/L (range, 10-89). Hematopoietic stem cell transplantation (HSCT) specific comorbidity index was ≥ 3 in 76% and 0-2 in 24% of patients. Twelve percent of patients received 4/8 HLA match, 59% 5/8 HLA match, 18% 6/8 HLA match, 6% 7/8 HLA match and 6% 8/8 HLA match.

The primary efficacy outcome measure was the incidence of early and sustained neutrophil recovery, defined as ANC ≥500 cells/µl for 3 consecutive measurements on different days by Day 26, maintained at Days 42 and 100 posttransplant. Other secondary efficacy outcomes were neutrophil recovery (days to first of three consecutive ANC≥500 cells/µL), red blood cell (RBC) transfusion independence (days to 30-day transfusion independence), platelet recovery ≥20,000/µL (days to first of 3 consecutive platelet count of 20,000/µL with no preceding transfusion in 7 days) and platelet transfusion independence (days to 30-day platelet transfusion independence).

The efficacy results are summarized in Table 7 below.

OMISIRGE (NDC 73441-800-04) is shipped in two shipping containers, a liquid nitrogen dry vapor shipper at ≤ -150℃, containing the two cryopreserved cell fractions (CF NDC 73441-100-01 and NF NDC 73441-200-01) and a Chimerism Testing Sample(s) and a refrigerated shipping container at 2-8℃, containing two Infusion Solutions (Infusion Solution for CF NDC 73441-300-01 and Infusion Solution for NF NDC 73441-400-01). OMISIRGE is shipped to the transplant center for a specific patient.

The Refrigerated Infusion Solutions

The Infusion Solutions (IS) used to dilute OMISIRGE CF and NF are provided in two IS bags labeled for the specific patient and for diluting the specific fraction. The IS for diluting the CF contains approximately 80 mL and the IS for diluting the NF contains approximately 40 mL of IS consisting of 6.8% Dextran 40 and 8% HSA. The Infusion Solutions are shipped in a refrigerated shipping container with the PI.

• Match the identity of the patient with the patient-specific identifiers on the IS bag labels upon receipt.
• Store the IS bags in a 2-8℃ refrigerated storage until the time of thaw of the OMISIRGE CF and NF.

Discuss the following with the patient receiving OMISIRGE:

The recommended course of therapy for OMISIRGE is a single dose for infusion, which is provided by the manufacturer as 2 separate components (CF and NF). OMISIRGE CF and OMISIRGE NF are infused one after the other once the patient has received an appropriate conditioning regimen.

Each OMISIRGE unit is specific to each patient. Ensure that patients understand the risk of manufacturing failure (8% in Study P0501) of OMISIRGE. In case of a manufacturing failure, a second manufacturing attempt may be considered. In this case, while the patient awaits the product, additional therapy (in addition to the preparative conditioning) may be necessary and may increase the risk of adverse events during the pre-infusion period.

Prior to infusion, advise patients of the following risks:
