Gamida Cell Reports Full Year 2022 Financial Results and Provides Company Update

Gamida Cell Ltd. (Nasdaq: GMDA), a cell therapy pioneer working to turn cells into powerful therapeutics, today provided a business update and reported financial results for the year ended December 31, 2022. Net loss for 2022 was $79.4 million, compared to a net loss of $89.8 million in 2021. As of December 31, 2022, Gamida Cell had total cash and cash equivalents of $64.7 million.

The company highlighted positive data, productive regulatory interactions and progress on commercial readiness activities supporting its lead product candidate, omidubicel, an advanced cell therapy candidate for allogeneic stem cell transplant, as it advances toward its May 1, 2023 target Prescription Drug User Fee Act (PDUFA) action date. The company also announced a strategic restructuring of its operations to prioritize launch of omidubicel to ensure that, if approved, patients who may potentially benefit will have access to therapy. To reduce expenses, the company will discontinue development of its preclinical NK cell therapy candidates while continuing to enroll patients in the GDA-201 Phase 1 clinical trial.

"Our mission is to bring potentially curative therapies to patients," said Abbey Jenkins, President and Chief Executive Officer of Gamida Cell. "We believe we have a clear path to approval and are preparing for the commercial launch of omidubicel, if approved. Given the challenging economic environment, to date, we have not been able to raise adequate funding to support our full pipeline and enable a more robust launch of omidubicel, if approved. As a result, we are taking decisive actions to do three things 1) prioritize resources toward the launch 2) reduce expenses across the board 3) seek potential commercial or strategic partnerships to maximize patient access to omidubicel, a potentially life-saving therapy. Today's actions are difficult. Especially since our engineered NK cell therapy candidates, which are derived from healthy donors, have demonstrated encouraging pre-clinical data that differentiate them from other NK cell therapy approaches. The science is promising, but these changes are economically necessary to ensure omidubicel reaches as many patients as possible."

Today Gamida Cell announced it would:

• Implement a strategic restructuring to focus on omidubicel launch, if approved: The company intends to allocate the vast majority of its resources to executing a launch of omidubicel, if approved, although with a more limited investment and slower ramp than previously planned in order to manage its financial resources. The company reported productive interactions with the FDA, including a recently completed Late Cycle Meeting and a previously reported Pre-Licensing Inspection of the company's Kiryat Gat, Israel, manufacturing facility, with no 483 observations received to date. Recently presented data continue to support the clinical benefits and safety of omidubicel, which, if approved, may be a valuable new donor source for patients in need of allogeneic stem cell transplant. Commercial readiness activities have made progress as the company prepares to onboard approximately 10-15 of the top 70 transplant centers in the United States in 2023. Omidubicel has received positive feedback from leading transplant centers, including ones that did not participate in the company's clinical trials. The company has met with U.S. payers, including payers that cover more than 90% of commercially covered lives, and reported that payers indicate they anticipate covering a one-time therapy with curative intent.

• Continue its GDA-201 Phase 1 study: The company will continue to enroll patients in its GDA-201 Phase 1 dose escalation study.

• Reduce operating expenses in order to extend its cash runway: The company will discontinue the development of its engineered NK cell therapy preclinical pipeline, including GDA-301, GDA-501 and GDA-601, while maintaining the IP to these candidates. It will implement a headcount reduction of 17%, with the majority of impacted headcount tied to the discontinuation of the pre-clinical NK cell therapy candidates. The company will also close its operations in Jerusalem and consolidate Israel operations at its state-of-the-art manufacturing facility in Kiryat Gat. These changes are expected to extend the company's cash runway through Q3 2023.

• Explore strategic options: The company intends to seek potential commercial or strategic partnerships to maximize patient access to omidubicel, if approved.

Fourth Quarter and Recent Developments

Omidubicel: Advanced Cell Therapy

• New data presented at ASH and TCT: The company presented new data characterizing peripheral blood lymphocytes measured in correlation with time to neutrophil and platelet engraftment in omidubicel-transplanted and standard cord blood-transplanted patients at the 2023 Tandem Meetings, Transplantation & Cellular Therapy (TCT) Meetings of the American Society for Transplantation & Cellular Therapy and the Center for International Blood and Marrow Transplant Research in February. Seven days post-transplant, omidubicel-transplanted patients showed a statistically significant correlation between CD3+/CD4+ T cell counts and time to neutrophil engraftment. Similar correlations were noted between CD3+/CD8+/CD19+ cell counts and time to platelet engraftment. Patients transplanted with standard cord blood showed no such correlations at Day 7 post-transplant, and only began to show correlations starting at 14 days post-transplant. Data support past findings that omidubicel stimulates a faster immune response than standard cord blood, which may be a contributing mechanism resulting in the lower incidence of serious bacterial, fungal and viral infections for omidubicel-transplanted patients.

• New publication in press: The company reported a publication in press in Transplantation and Cellular Therapy, now available online, reporting on long-term follow-up of patients transplanted with omidubicel across five clinical trials. The analysis showed a three-year overall survival of 62.5% and disease-free survival of 54%. With up to 10 years of follow-up, omidubicel showed durable hematopoiesis.

• Manufacturing readiness: The company's state-of-the-art manufacturing facility in Kiryat Gat, Israel, is ready for commercial launch if omidubicel is approved and is currently producing omidubicel for the company's Extended Access Program (EAP) and its ongoing omidubicel aplastic anemia study. The facility, which has completed its Israeli Ministry of Health and FDA pre-licensure inspections with no 483 observations to date, has the ability to deliver omidubicel back to the transplant center within approximately 30 days from the start of manufacturing.

• Commercial readiness: The company continues to advance efforts throughout the organization to prepare for the launch of omidubicel, if approved.

GDA-201: Intrinsic NK Cell Therapy

• New data presented at Tandem Meetings: The company presented a poster at the 2023 Tandem Meetings, Transplantation & Cellular Therapy (TCT) Meetings of the American Society for Transplantation & Cellular Therapy and the Center for International Blood and Marrow Transplant Research reporting new preclinical data on the cryopreserved formulation of GDA-201, which showed increased potency and enhanced cytotoxicity. GDA-201 cells were tested for viability, phenotyping, function and potency. Previous characterization of GDA-201 showed high levels of CD56, CD16, CD49a and CD62L expression, low levels of CD57, and low levels of immune checkpoints such as LAG3 and CD200R. The new analyses showed that cryopreserved GDA-201 exhibited high viability (>90%) and high purity up to 12 months post-manufacturing and preserved the ability to proliferate post-thaw. GDA-201 maintained high levels of expression of CD16, which mediates antibody-dependent cellular toxicity, and CD62L, which is a homing and retention marker. GDA-201 also demonstrated high potency, based on the intracellular secretion of TNF-alpha & IFN-gamma and extracellular degranulation marker CD107a.
  
  In addition, external investigator Veronika Bachanova, M.D., Ph.D., Professor at the University of Minnesota Medical School, gave an oral presentation highlighting novel observations of "on treatment" tumor biopsies from eight patients treated with GDA-201 in a Phase 1 study. The microscopic spatial analysis demonstrated that while GDA-201 cells were virtually undetectable in tumors after 14 days, T cells were observed in 50-95% of tumor site cellularity. Most biopsies obtained as early as three to seven days post-infusion showed strong indications of widespread tumor death. These observations suggest that GDA-201 infusions trigger profound immune microenvironment changes, supporting the influx of host T cells early post-GDA-201 infusion. These findings further suggest the engagement of the adaptive immune system and effective tumor elimination.

Corporate Developments

• On March 20, the company announced that Shawn Cline Tomasello was elected Chairwoman of the Board of Directors, succeeding Chairman Robert I. Blum, who resigned. Ms. Tomasello joined the Gamida Cell Board of Directors in June 2019.

Full Year 2022 Financial Results

• Research and development expenses, net were $42.7 million in 2022, compared to $50.2 million in 2021. The decrease was primarily due to a $9.6 million decrease in clinical and operational activities relating to the conclusion of our Phase 3 study of omidubicel, offset by an increase of $1.1 million in T&E and other expenses as well as a $1.0 million decrease in Israeli Innovation Authority grants.
• Commercial expenses in 2022 were $12.9 million, compared to $20.0 million in 2021. The decrease was primarily due to a $8.2 million decrease in commercial launch readiness expenses, offset by an increase of $1.1 million in headcount related expenses.
• General and administrative expenses were $19.4 million in 2022, compared to $17.0 million in 2021. The increase was mainly driven by an increase of $1.4 million attributed to our corporate headquarters and headcount-related expenses as well as a $1.0 million increase in professional services expenses.
• Financial expenses, net, were $4.4 million for 2022, compared to $2.6 million for 2021. The increase was primarily due to expenses relating to the closing on a senior secured convertible term loan of $25 million with certain funds managed by Highbridge Capital Management, LLC.
• Net loss for 2022 was $79.4 million, compared to $89.8 million in 2021.

About Omidubicel

Omidubicel is an advanced cell therapy candidate for allogeneic hematopoietic stem cell (bone marrow) transplant that, if approved, has the potential to expand access and improve outcomes for patients with blood cancers. Omidubicel demonstrated a statistically significant reduction in time to neutrophil engraftment compared to standard umbilical cord blood in an international, multicenter, randomized Phase 3 study (NCT02730299) in patients with hematologic malignancies undergoing allogeneic bone marrow transplant. The Phase 3 study also showed reduced time to platelet engraftment, reduced infections and fewer days of hospitalization. One-year post-transplant data showed sustained clinical benefits with omidubicel as demonstrated by a significant reduction in infectious complications as well as reduced non-relapse mortality and no significant increase in relapse rates nor increases in graft-versus-host-disease (GvHD) rates. Omidubicel is the first stem cell transplant donor source to receive Breakthrough Therapy Designation from the FDA and has also received Orphan Drug Designation in the U.S. and E.U. Omidubicel has a PDUFA target action date of May 1, 2023.

Omidubicel is an investigational stem cell therapy candidate, and its safety and efficacy have not been established by the FDA or any other health authority. For more information about omidubicel, please visit https://www.gamida-cell.com.

About GDA-201

GDA-201 is an intrinsic NK cell therapy candidate being investigated for the treatment of hematologic malignancies. Preclinical studies have shown that GDA-201 may address key limitations of NK cells by increasing the cytotoxicity and in vivo retention and proliferation in the bone marrow and lymphoid organs. Furthermore, these data suggest GDA-201 may improve antibody-dependent cellular cytotoxicity (ADCC) and tumor targeting of NK cells. A multicenter Phase 1/2 study of GDA-201 for the treatment of non-Hodgkin lymphoma is ongoing.

GDA-201 is an investigational cell therapy candidate, and its safety and efficacy have not been established by the FDA or any other health authority.
