Gamida Cell Reports First Quarter 2020 Financial Results and Provides Company Update

Gamida Cell Ltd. (Nasdaq: GMDA), an advanced cell therapy company committed to finding cures for blood cancers and serious blood diseases, today reported financial results for the quarter ended March 31, 2020. The company also highlighted continued progress in advancing its clinical development candidates: omidubicel, an advanced cell therapy in Phase 3 clinical development as a potentially life-saving treatment option for patients in need of bone marrow transplant, and GDA-201, an investigational, natural killer (NK) cell-based cancer immunotherapy in Phase 1 development in patients with non-Hodgkin lymphoma (NHL) and multiple myeloma.

"Last week, we were extraordinarily pleased to report that our Phase 3 study of omidubicel met its primary endpoint of demonstrating a significant reduction in time to neutrophil engraftment, a key milestone in recovery from a bone marrow transplant. Shortening the time to engraftment is clinically meaningful, as it can reduce a patient's time in the hospital and decrease likelihood of infection. These positive study results represent an important step forward for Gamida Cell and the transplant community," stated Julian Adams, Ph.D., chief executive officer of Gamida Cell. "Omidubicel is the first bone marrow transplant product to receive Breakthrough Therapy Designation from the U.S. FDA and has the potential to be the first FDA-approved bone marrow transplant graft. Our dedicated team is working hard to begin submitting the biologics license application for omidubicel to the FDA on a rolling basis in the fourth quarter."

"Our Phase 3 omidubicel data underscore the potential of our proprietary NAM technology platform, and we're very encouraged by the data in the ongoing Phase 1 study of our second development candidate, GDA-201, an investigational natural killer cell therapy. Natural killer cells have attracted significant attention as a potential breakthrough approach to treat cancer, and we are proud to be at the forefront of advancing this field. We anticipate reporting additional data on GDA-201 in the second half of 2020 and are working to initiate a multi-center Phase 1/2 clinical study in patients with lymphoma next year," Dr. Adams continued.

Company Highlights

• Reported positive topline data from Phase 3 study of omidubicel: Last week, Gamida Cell announced positive topline data from its international, randomized Phase 3 study of omidubicel. The study was designed to evaluate the safety and efficacy of omidubicel in 125 patients with high-risk hematologic malignancies undergoing a bone marrow transplant compared to a comparator group of patients who received a standard umbilical cord blood transplant. The primary endpoint was time to neutrophil engraftment.
  
  The study achieved its primary endpoint (p<0.001). In the intent-to-treat analysis, the median time to neutrophil engraftment was significantly shorter for patients who were randomized to omidubicel (12 days; 95% CI: 10-15 days) compared to the comparator group (22 days; 95% CI: 19-25 days). Omidubicel was generally well tolerated. Among patients who were transplanted per protocol, 96 percent of patients who received omidubicel achieved successful neutrophil engraftment, compared to 88 percent of patients in the comparator group.
  
  The study included patients aged 12?65 years with high-risk hematologic malignancies and was conducted at more than 50 clinical centers in the United States, Latin America, Europe and Asia. The demographics and baseline characteristics were well-balanced across the two study groups.
  
  Gamida Cell expects to present the full Phase 3 data set at a medical meeting later this year and submit a rolling biologics license application to the FDA in the fourth quarter of 2020.

• Announced $60 million public offering: On May 18, Gamida cell announced the pricing of an underwritten public offering of 13,333,334 ordinary shares at a public offering price of $4.50 per share for aggregate gross proceeds of approximately $60 million, before deducting underwriting discounts and commissions and estimated offering expenses. In addition, Gamida Cell granted the underwriters a 30-day option to purchase up to an additional 2,000,000 ordinary shares at the public offering price, less the underwriting discounts and commissions. The offering is expected to close today, subject to satisfaction of customary closing conditions.

• Continued to focus on activities required to successfully bring omidubicel to patients: Gamida Cell is continuing to advance key activities required to bring omidubicel to patients in a commercial setting, including building out manufacturing infrastructure, assembling an experienced commercial team with expertise in cell therapy and transplant, establishing hospital services and patient assistance programs, and exploring coverage and reimbursement models to enable access.

• Published updated data for GDA-201: In February 2020, updated data from the ongoing Phase 1 clinical study of GDA-201 in patients with non-Hodgkin lymphoma (NHL) and multiple myeloma (MM) was reported in an abstract published in advance of the 46^th European Society for Blood Marrow Transplantation (EBMT) Annual Meeting, which was subsequently postponed due to COVID-19. The data from the first 25 patients demonstrated that GDA-201 was clinically active and generally well tolerated. Among the eleven patients with NHL, seven patients achieved a complete response and one patient achieved a partial response. Among the patients with MM, one patient achieved a complete response, and four patients achieved stable disease. Gamida Cell expects to provide updated data from the study at a medical conference in the second half of 2020.

• Continued preparations for the next clinical study of GDA-201: Based on the data from the ongoing Phase 1 study of GDA-201 previously presented, Gamida Cell expects to submit an investigational new drug application to the FDA in the fourth quarter of 2020 to enable the initiation of a multi-center Phase 1/2 clinical study in patients with NHL.

COVID-19 Operational Impact

Gamida Cell has taken important steps to help ensure the safety of employees and their families and to reduce the spread of COVID-19. In early March, Gamida Cell established a work-from-home policy for all employees, other than those performing or supporting business-critical laboratory-based experiments and manufacturing-related activities. For those employees, the company has implemented stringent safety measures designed to comply with applicable government guidelines instituted in response to the COVID-19 pandemic. Gamida Cell has maintained frequent communication with its business partners and clinical sites as the COVID-19 situation has progressed.

"We are proud of the resilience of our employees and are thankful for the continued dedication and support of our clinical study investigators and participating patients. COVID-19 has slightly slowed the cadence of new patient enrollment in the ongoing clinical study of GDA-201 and changed how we conduct our day-to-day business. However, we anticipate that COVID-19 will have limited overall impact on our clinical development programs, timing of regulatory submission for omidubicel, or manufacturing readiness for the potential launch of omidubicel in 2021," said Dr. Ronit Simantov, chief medical officer at Gamida Cell.
