Company to host conference call today at 8:30 a.m. ET

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 quarter ended June 30, 2023.

“Since the approval of Omisirge in April, Gamida Cell has made excellent progress on the launch,” said Abbey Jenkins, President and Chief Executive Officer of Gamida Cell. “We have rapidly confirmed significant payer coverage and are seeing high interest from transplant centers, exceeding our plans. This is a testament to the unmet needs that Omisirge has the potential to address for patients, as well as the exceptional work of our experienced cell therapy team. We continue to progress our discussions in our efforts to secure a strategic deal to fully resource our Omisirge commercial efforts. We are optimistic that between our progress on the Omisirge launch and our discussions with potential partners, we can accelerate efforts to expand patient access to Omisirge.”

The U.S. Food and Drug Administration (FDA) approved Omisirge in April 2023 for use in adult and pediatric patients 12 years and older with hematologic malignancies planned for umbilical cord blood transplantation. The Omisirge launch is ahead of expectations in terms of both transplant center onboarding and market access, with 12 transplant centers already onboarded, eight more in the onboarding process, and active engagement with virtually all of the top 70 transplant centers. The company has also confirmed coverage with payers that cover more than 85% of commercial lives, as well as confirmed coverage and reimbursement with Medicare from the Centers for Medicare and Medicaid Services (CMS). All documents are in place for coverage under the Department of Veterans Affairs, Department of Defense and Medicaid.

“We are very encouraged by the strong interest we have received from transplant centers to date, including centers that did not participate in our clinical studies,” said Michele Korfin, Chief Operating and Chief Commercial Officer of Gamida Cell. “The enthusiasm for Omisirge is consistent with expectations from the market research we conducted both pre- and post-approval, supporting our assertion that Omisirge has the potential to capture approximately 20% peak market share. We anticipate this peak share will include patients who might have been otherwise transplanted with a different donor source, as well as patients who historically would not have been able to find an appropriate donor. We have onboarded more centers at this point in our launch than we initially anticipated and are ahead of our expectations in terms of payer coverage. We look forward to engaging with and onboarding additional transplant centers in the coming months to provide more access to Omisirge for patients.”

Second Quarter Highlights and Recent Developments

Omisirge

• Commercial progress:
  • The company is seeing strong demand from transplant centers and is ahead of its goal of onboarding 10-15 transplant centers in 2023. As of the morning of August 14, 2023, 12 transplant centers have been onboarded and eight additional transplant centers are in the onboarding process.
  • Patients are enrolled in the company’s Gamida Cell Assist program, which means that their transplanter has the intent to utilize Omisirge as the patient’s donor source.
  • The company has confirmed coverage with payers who cover more than 85% of commercial lives and is in ongoing discussions with additional commercial payers.
  • CMS coverage and reimbursement has been confirmed for patients covered by Medicare. All required documentation is in place for patients who are covered under Medicaid, Department of Defense and Veterans Affairs.
  • The company is ready to reliably deliver Omisirge within 30 days from the start of manufacturing.

• Publication: The company announced the publication of a prospective sub-study of the Phase 3 clinical trial for Omisirge titled “Immune Reconstitution Profiling Suggests Antiviral Protection After Transplantation with Omidubicel: A Phase 3 Substudy.” The publication is available online on the Transplantation and Cellular Therapy journal website.

Corporate Developments

• Strategic review: The company continues to work with Moelis & Company LLC to engage and advance discussions with multiple parties as part of its efforts to explore alternatives to support a fully resourced launch.

• Terry Coelho, MBA, appointed Chief Financial Officer: In May 2023, Gamida Cell announced the appointment of Terry Coelho as Chief Financial Officer. Ms. Coelho, a seasoned finance executive with more than 35 years of experience across all areas of finance and business development at emerging growth companies and established global companies, is positioned to support Gamida Cell’s transition into a commercial-phase company and its pursuit of a strategic partnership.

• Jeremy Blank appointed to Board of Directors: In August 2023, the company’s Board of Directors appointed Jeremy Blank, Chief Investment Officer of Community Fund, to the Board, where he will serve on the Transactions Committee. “Having closely followed Gamida Cell for over a decade, it is a privilege to join the Board of Directors,” said Mr. Blank. “I have high confidence in Gamida’s team and technology and our firm invested in both of Gamida’s most recent equity offerings. I look forward to supporting Gamida’s strategic process which is a great opportunity to create shareholder value.” Mr. Blank will provide a valuable perspective to the Board as it aids the company in executing its corporate strategy. From 2005 to 2020, Mr. Blank also served as a partner at York Capital Management, a $15 billion global investment fund. Before that, he was a Vice President and credit analyst at Morgan Stanley. Mr. Blank currently serves as a Director on the boards of Insightec Ltd. and Advanced Emissions Solutions, Inc. (NASDAQ: ADES). Community Fund is a significant shareholder in Gamida Cell.

• Strengthened balance sheet: The company ended the second quarter with $54.1 million in cash as a result of the net proceeds of $29.8 million from both the April equity offering and the at-the-market offering (ATM), thereby extending cash runway into the second quarter of 2024. Additionally, the company reduced its outstanding principal balance in the quarter by $9.0 million, from $94.0 million to $85.0 million.

• Investor Day: Gamida Cell hosted an Investor Day on June 29, 2023. The event was attended by over 180 participants, both in-person and virtual, and included an update on the commercial launch of Omisirge as well as discussions with industry thought leaders. Steven Devine, M.D., Chief Medical Officer at the National Marrow Donor Program® (NMDP)/Be The Match^®, discussed the unmet needs and barriers to care in stem cell transplant, and explained how Omisirge can help address some of these issues. Usama Gergis, M.D., MBA, Professor of Oncology & Director of Transplant and Cellular Therapy, Sidney Kimmel Cancer Center, Thomas Jefferson University, discussed the implications of a health outcomes economics research model developed in partnership with Gamida Cell that showed that a 20% peak market share of Omisirge may increase transplant access for eligible patients, particularly those from racially and ethnically diverse groups that are currently underserved.

GDA-201

• Phase 1 study: Gamida Cell’s GDA-201, an intrinsic natural killer (NK) cell therapy candidate being investigated for the treatment of hematologic malignancies, is being evaluated in an ongoing Phase 1 study for treatment of non-Hodgkin lymphoma. The study is continuing to enroll patients at six sites in the U.S. Data are expected in the first quarter of 2024.

• Data presented at International Society for Cell and Gene Therapy (ISCT) 2023 Annual Meeting: GDA-201 data presented at ISCT on June 2, 2023 demonstrated the robustness of cryopreserved GDA-201 and continued to support signs of strong lymphoid homing and decreased exhaustion of GDA-201 cells.

• New data on nicotinamide (NAM) mechanism of action: Data published in Science Translational Medicine in the July 19 edition demonstrated that culturing NK cells with NAM, which the company uses to enhance and expand cells, and IL-15 increases metabolic fitness, energy charge and glucose flux within NK cells, providing a pathway for resistance to oxidative stress and increased potency compared to NK cells cultured with IL-15 but without NAM. Through preventing degradation of the protein FOXO1, the presence of NAM was found to increase levels of CD62L, an important lymph node homing marker. This expression cascade provides evidence for the strong lymph node homing, direct killing and antibody dependent cell-mediated cytotoxicity capabilities of NK cells cultured with NAM. The publication also includes outcome data from the Phase 1 dose escalation clinical trial for Gamida Cell’s NK cell therapy candidate GDA-201 in patients with non-Hodgkin lymphoma as well as translational data from biopsy specimens.

Second Quarter 2023 Financial Results

• Research and development expenses were $8.7 million in the second quarter of 2023, compared to $10.6 million in the same quarter in 2022. The decrease of $1.9 million was primarily due to a $1.6 million reduction associated with the discontinuation of development of our engineered NK cell therapy pipeline, and $0.7 million in lower Omisirge Phase 3 spend, including a decrease in payments for manufacturing services, partially offset by a decrease of $0.4 million in IIA (Israeli Innovation Authority) income.

• Commercial expenses were $3.9 million in the second quarter of 2023, compared to $3.2 million in the second quarter of 2022. The increase of $0.7 million was attributable to an increase in launch readiness activities.

• General and administrative expenses were $6.3 million in the second quarter of 2023, compared to $4.3 million in the same period in 2022. The increase of $2.0 million was associated with higher professional services expenses, in part due to the April 2023 follow on offering and business development activities.

• Financial expenses, net, were $12.9 million in the second quarter of 2023, compared to $0.5 million in the same period of 2022. The increase of $12.4 million was primarily due to non-cash expenses totaling approximately $10.4 million, including the fair value impact on our warrants liability of $4.9 million, the fair value impact on the 2022 convertible note of $4.3 million, and a decrease in capitalization of finance costs to fixed assets of $0.6 million. In addition, the increase was due to higher cash expenses of $2.0 million, including $1.7 million in issuance costs from our April 2023 underwritten public offering and an increase of $1.0 million in interest expenses associated with the 2022 convertible notes, partially offset by increased interest income of $0.5 million.

• Net loss was $31.7 million in the second quarter of 2023, compared to a net loss of $18.6 million in the second quarter of 2022, driven primarily by the increase in financial expenses of $12.4 million.

• Cash Position: As of June 30, 2023, Gamida Cell had total cash and cash equivalents of $54.1 million compared to $64.7 million as of December 31, 2022. The decrease of $10.4 million is due primarily to net cash used in operating activities of $44.3 million partially offset by $34.7 million in net cash proceeds from the issuance of shares and warrants from our underwritten public offering and the issuance of shares via the ATM facility. Subsequent to the quarter close and through August 9^th, the company raised an additional $14.0 million in net proceeds via the ATM facility. The company expects its current cash and cash equivalents, including the funds raised subsequent to the close of the second quarter, to support its ongoing operating activities into the second quarter of 2024, based on Gamida Cell’s current operational plans and excluding commercialization activities beyond the initial launch of Omisirge, as well as any additional financing activities that may be undertaken.

• Debt Position: As of June 30, 2023, the company had reduced its principal balance on the 2022 secured convertible note by $15.0 million, from $25.0 million as of December 31, 2022, to $10.0 million at the end of the second quarter. The company also holds a 2021 convertible senior note with an aggregate principal amount of $75.0 million.
