Gamida Cell Ltd. (Nasdaq: GMDA), the leader in the development of NAM-enabled cell therapies for patients with hematologic and solid cancers and other serious diseases, today provided a business update and reported financial results for the quarter ended March 31, 2022. Net loss for the first quarter of 2022 was $20.2 million, compared to a net loss of $19.2 million in the first quarter of 2021. As of March 31, 2022, Gamida Cell had total cash and cash equivalents of $69.7 million.

During the past quarter, Gamida Cell:

• Progressed omidubicel, a potentially life-saving cell therapy candidate for patients with blood cancers in need of stem cell transplant, towards full Biologics License Application (BLA) submission to the U.S. Food and Drug Administration (FDA) in the second quarter of this year.
• Planning to open sites for enrollment in second quarter of 2022 for Phase 1/2 study of lead natural killer (NK) cell therapy candidate, GDA-201, for patients with follicular and diffuse large B-cell lymphomas. The FDA recently cleared the company’s Investigational New Drug (IND) application and removed the clinical hold on the program, allowing Gamida Cell to move forward with the planned Phase 1/2 study with the cryopreserved formulation.
• Continued development of the company’s NAM-enabled NK cell pipeline, including genetically modified product candidates GDA-301, GDA-401, GDA-501 and GDA-601, which focus on solid-tumor and hematological cancers. These product candidates utilize CAR, membrane bound- and CRISPR-mediated technologies to increase the NK cell targeting, potency and persistence against hematologic malignancies and solid tumors.

“We have made significant strides advancing our pipeline and demonstrating the potential benefit of our NAM-enabled cell therapy candidates for patients with blood cancers and other serious blood,” said Julian Adams, Ph.D., chief executive officer of Gamida Cell. “And this starts with the recent milestone of the clearance of our IND for the cryopreserved formulation of GDA-201 by removal of the clinical hold. We are proceeding with operational activities in second quarter at multiple sites for our planned Phase 1/2 study, and are on track to advance this novel cell therapy candidate to the clinic this year. We were also pleased to present important data on omidubicel, supporting its potential long term clinical benefit, as we approach the full BLA submission for omidubicel during the second quarter of this year.”

First Quarter and Recent Developments

Omidubicel: Advanced Cell Therapy

• BLA submission: Following the receipt of positive Type B meeting correspondence from the FDA confirming that analytical comparability has been established between product made at Gamida Cell’s wholly-owned commercial manufacturing facility and the product that was manufactured for the Phase 3 study, Gamida Cell initiated a rolling BLA submission for omidubicel in February 2022. The company is on-track to complete the BLA submission in the second quarter of 2022. In parallel with the BLA submission, Gamida Cell is assessing alternatives for the commercialization of omidubicel, including potential U.S. or global partnerships.
• New data presented at the 2022 Transplantation & Cellular Therapy Meetings of ASTCT and CIBMTR Tandem Meetings (TCT): In April 2022, Gamida Cell announced two oral and six poster presentations that focused on omidubicel’s positive Phase 3 clinical data, Gamida Cell’s health economic efforts, and transcriptional and metabolic profiling for our lead NK candidate, GDA-201. These presentations continued to add to the totality of evidence supporting omidubicel as a potential allogeneic hematopoietic stem cell transplant and our developments with our NK candidates. Highlights from these presentations included:
  • A presentation which received TCT’s Best Abstract Award entitled “Hematopoietic Stem Cell Transplantation (HSCT) with Omidubicel is Associated with Enhanced Circulatory Plasmacytoid Dendritic Cells (pDC), NK Cells and CD4+ T Cells with Lower Rates of Severe Infections Compared to Standard Umbilical Cord Blood Transplantation.” This presentation detailed that Allo-HSCT with omidubicel demonstrated rapid hematopoietic recovery, reduced rates of infections and no increase in acute or chronic GvHD rates compared with standard UCB, with no unexpected adverse events attributable to ex vivo expansion.
  • An oral presentation titled “Allogeneic Hematopoietic Stem Cell (allo-HSCT) Transplant with Omidubicel Demonstrates Sustained Clinical Improvement Versus Standard Myeloablative Umbilical Cord Blood Transplantation (UCBT): Final Results of a Phase III Randomized, Multicenter Study.” The data showed that the advantages of early engraftment and lower infections with omidubicel translated into long term clinical benefits in the first-year post-transplant, as demonstrated by reduction in non-relapse mortality, and no increase in relapse or GvHD rate compared to Umbilical Cord Blood Transplantation (UCBT). Additionally, there was a continued trend toward improved OS in favor of the omidubicel arm over time (73% vs 60%).
  • A health economic study titled “Projected Impact of Omidubicel on Racial and Ethnic Disparities in Allogeneic Hematopoietic Cell Transplant (allo-HCT) Access and Outcomes for Patients with Hematologic Malignancies in the US.” The study, which assessed the projected impact of omidubicel on racial and ethnic health disparities in a projection model, showed that, if approved, broad access to omidubicel was projected to decrease time to allo-HCT and improve allo-HCT outcomes overall, with the greatest improvements among racial and ethnic groups least served by current graft sources.

GDA-201: NAM-Enabled NK Cell Therapy

• IND cleared and clinical hold removed for Phase 1/2 Study with cryopreserved formulation of GDA-201: Gamida Cell recently announced that FDA cleared its IND application and removed the clinical hold for a cryopreserved formulation of GDA-201. The company is now proceeding with operational activities at several clinical trial sites, and is on track to initiate a company-sponsored Phase 1/2 clinical study in patients with follicular and diffuse large B-cell lymphomas in 2022.

NAM-Enabled NK Cell Pipeline Expansion

• Progressed NAM-enabled genetically modified NK pipeline: Gamida Cell continues to progress its NAM-enabled genetically modified NK pipeline, which utilizes CAR, membrane bound- and CRISPR-mediated technologies to increase targeting, potency and persistence against hematologic malignancies and solid tumors. The company plans to conduct preclinical proof of concept studies for these genetically modified NK therapeutic targets and to select a product candidate for IND enabling studies by the end of 2022. These therapeutic targets include:
  • GDA-301: Knockout of CISH (cytokine inducible SH2 containing protein) in NK cells using CRISPR/Cas9 in combination with a membrane-bound IL-15/IL-15Ra;
  • GDA-401: A development candidate with an undisclosed target.
  • GDA-501: Anti HER2 CAR-engineered NK cells to target solid tumors expressing HER2, based on a single-chain variable fragment of the widely used humanized monoclonal antibody trastuzumab; and
  • GDA-601: CRISPR Knockout of CD38 on NK cells combined with anti CD38 CAR. CD38 is an established immunotherapeutic target in multiple myeloma, but its expression on NK cells and its further induction during ex vivo NK cell expansion represents a barrier to the development of an anti CD38 CAR-NK cell therapy. Gamida Cell is advancing this program in collaboration with the Dana-Farber Cancer Institute to study the in vitro cytotoxicity of GDA-601 in fresh samples from multiple myeloma patients.
• Presented preclinical data from product candidates at the International Society for Cell & Gene Therapy (ISCT) 2022: Gamida Cell recently presented new preclinical data for GDA-301 and GDA-601 that continued to demonstrate the potential of these product candidates:
  • A poster titled “GDA-301: Engineered NAM-NK Cells via CISH Knockout and Membrane-Bound IL-15 Expression Increases Cytotoxicity Against Malignancies,” detailed that GDA-301 produces enhanced potency and persistence with combined genetic manipulation of CISH gene editing and the engineered expression of membrane-bound IL-15 for targeting hematologic malignancies and solid tumors.
  • In a poster titled “GDA-601: NAM-NK Cells With CD38 Knockout Expresses Enhanced CD38 Chimeric Antigen Receptor and Targets Multiple Myeloma Cells With Increased Cytotoxicity,” it was shown that GDA-601 displays superior antitumoral responses against multiple myeloma cells and represents a promising adoptive cell therapeutic strategy.

First Quarter 2022 Financial Results

• Research and development expenses were $11.3 million in the first quarter of 2022, compared to $11.4 million in the same quarter in 2021. The decrease was primarily due to a $1.1 million decrease in omidubicel and GDA 201 clinical study activities, offset by an increase of $1.0 million in broadening the company’s scientific capabilities and talent.
• Commercial expenses were $3.9 million in the first quarter of 2022, compared to $4.2 million in the first quarter of 2021. The decrease was attributable mainly to reducing the company’s near-term commercial readiness expenses, as it is assessing alternatives for the commercialization of omidubicel, including potential U.S. or global partnerships.
• General and administrative expenses were $4.1 million in the first quarter of 2022, compared to $3.5 million in the same period in 2021. The increase was mainly due to a $0.5 million increase in headcount and related expenses.
• Finance expenses, net, were $0.9 million in the first quarter of 2022, compared to $0.1 million in the same period in 2021. The increase was primarily due to a $0.6 million increase in interest expenses from convertible notes.
• Net loss was $20.2 million in the first quarter of 2022, compared to a net loss of $19.2 million in the first quarter of 2021.

About Omidubicel

Omidubicel is an advanced cell therapy candidate under development as a potential life-saving allogeneic hematopoietic stem cell (bone marrow) transplant for patients with blood cancers. Omidubicel is the first stem cell transplant donor source to receive Breakthrough Therapy Designation from the U.S. FDA and has also received Orphan Drug Designation in the U.S. and EU. Gamida Cell has completed an international, multi-center, randomized Phase 3 study (NCT0273029) evaluating the safety and efficacy of omidubicel in patients with hematologic malignancies undergoing allogeneic bone marrow transplant compared to a comparator group of patients who received a standard umbilical cord blood transplant. That study achieved its primary endpoint, demonstrating a highly statistically significant reduction in time to neutrophil engraftment, a key milestone in a patient’s recovery from a stem cell transplant. The Phase 3 study also achieved its secondary endpoints of reduced time to platelet engraftment, reduced infections and fewer days of hospitalization. Gamida Cell initiated a rolling BLA submission for omidubicel in the first quarter of 2022 with full BLA submission on track for the second quarter of 2022. In 2019, approximately 8,000 patients who were 12 years old and up with hematologic malignancies underwent an allogeneic stem cell transplant. Unfortunately it is estimated that another 1,200 patients were eligible for transplant but could not find a donor source. Omidubicel has the opportunity, upon FDA approval to improve outcomes for patients based on transplanter feedback and increase access for patients to get to transplant. Omidubicel has the potential to treat approximately 2000 – 2500 patients each year in the U.S. For more information about omidubicel, please visit https://www.gamida-cell.com.

Omidubicel is an investigational therapy, and its safety and efficacy have not been established by the FDA or any other health authority.

About GDA-201

Gamida Cell applied the capabilities of its nicotinamide (NAM)-enabled cell expansion technology to develop GDA-201, an innate NK cell immunotherapy candidate for the treatment of hematologic and solid tumors in combination with standard of care antibody therapies. GDA-201, the lead candidate in the NAM-enabled NK cell pipeline, has demonstrated promising initial clinical trial results. GDA-201 addresses key limitations of NK cells by increasing the cytotoxicity and in vivo retention and proliferation in the bone marrow and lymphoid organs. Furthermore, GDA-201 improves antibody-dependent cellular cytotoxicity (ADCC) and tumor targeting of NK cells. There are approximately 40,000 patients with relapsed/refractory lymphoma in the E.U.5 and U.S. which is the patient population that will be studied in the GDA-201 Phase 1/2 clinical trial.
