SEATTLE, Aug. 03, 2023 (GLOBE NEWSWIRE) -- Sana Biotechnology, Inc. (NASDAQ: SANA), a company focused on changing the possible for patients through engineered cells, today reported financial results and business highlights for the second quarter 2023.

“We continue to execute on our plans to deliver clinical data using Sana’s hypoimmune (HIP) technology in two studies later in 2023, providing insight into how the promising preclinical HIP data translate into people,” said Steve Harr, Sana’s President and Chief Executive Officer. “If the HIP technology is effective in preventing rejection of allogeneic cells, we believe it can rapidly translate into important therapeutics for various blood cancers, B-cell mediated autoimmune diseases, and type 1 diabetes. We are on track to advance our emerging clinical pipeline and file multiple additional INDs this year, and we have the balance sheet to enable multiple clinical data readouts from our pipeline.”

Recent Corporate Highlights

Opportunity for clinical proof of concept for two different first-in-human studies, each with the potential for initial clinical data this year

• The ARDENT trial evaluates SC291, an ex vivo hypoimmune-modified CD19-directed allogeneic CAR T cell therapy, in patients with B-cell malignancies. The goal of the hypoimmune platform is to overcome the immunologic rejection of allogeneic cells, which, if successful with SC291, may result in longer CAR T cell persistence and a higher rate of durable complete responses for these patients.
  • Enrollment in the ARDENT Phase 1 study continued.
  • SC291 has the potential to serve as clinical proof-of-platform for other hypoimmune-modified CAR T cell candidates using clinically-validated or commercially-approved CAR constructs in development at Sana for hematological malignancies, such as SC262 (CD22) and SC255 (BCMA). Sana’s goal is to file an IND for SC262 later this year and for SC255 in 2024.
• Sana is developing SC451, a hypoimmune-modified stem-cell derived islet cell therapy for patients with type 1 diabetes. SC451, which is engineered with Sana’s hypoimmune technology, has the potential to replace missing islet cells without immunosuppression in persons with type 1 diabetes by evading allogeneic and autoimmune responses.
  • Sana expects initial data later this year from an investigator-sponsored trial transplanting hypoimmune-modified primary human islet cells into type 1 diabetes patients. The goal of the study is to show safety, cell survival, immune evasion, and C-peptide production without the need for immunosuppression.
  • Sana’s goal is to file an IND for SC451 in 2024.

Published preclinical data in Nature Communications describing immune evasion, persistence, and durable anti-tumor activity of Sana’s hypoimmune-modified CD19-directed CAR T cells

• Sana developed hypoimmune-modified CD19 targeted allogeneic CAR T cells and compared them to unmodified CD19-targeted allogeneic CAR T cells in a murine leukemia model with a humanized immune system.
• Although both hypoimmune-modified and unmodified CAR T cells showed robust early tumor killing, cell durability was much greater in humanized mice treated with hypoimmune-modified cells. Hypoimmune-modified allogeneic CAR T cells persisted and removed all evidence of tumor for the duration of the study. Hypoimmune-modified CAR T cells also cleared all evidence of tumor after re-injection with cancer cells 90 days into the study. In contrast and consistent with the experience in patients to date, unmodified allogeneic CAR T cells showed greatly reduced persistence and a high rate of tumor recurrence in this model.
• These studies provide additional insight for SC291 and the allogeneic hypoimmune CAR T platform more broadly, including SC262 and SC255.

Published preclinical data in Science Translational Medicine demonstrating that Sana’s hypoimmune-modified pseudo-islets control type 1 diabetes

• Sana developed hypoimmune-modified human islet cells, which cluster into effective endocrine organoids termed “pseudo islets” (p-islets) and studied these p-islets in multiple preclinical models.
• Preclinical data showed that p-islets survive, persist, escape allogeneic rejection, and normalize blood glucose in diabetic models with humanized immune systems.
• Two different murine models showed that the hypoimmune-modified cells can evade autoimmune rejection and normalize blood glucose. First, these cells were studied in the standard model for autoimmunity in diabetes. Second, Sana created a humanized mouse model with immune cells from a diabetic person and transplanted pancreatic islet cells derived from the diabetic person’s stem cells. In both cases, unmodified pancreatic islet cells were rapidly cleared by the immune system. In contrast, hypoimmune-modified pancreatic islet cells survived, persisted, and provided sustained blood glucose control in both models.
• These studies provide additional insight for SC451 in persons with type 1 diabetes.

Published preclinical data in Nature Biotechnology demonstrating that Sana’s hypoimmune-modified cells survive allogeneic transplant across several species, including non-human primates (NHPs) with normal immune systems, and remain fully functional

• Sana developed hypoimmune-modified NHP induced pluripotent stem cells (iPSCs) and transplanted them into immunocompetent NHPs. Results were compared to transplantation of unmodified iPSCs into immunocompetent NHPs.
• Data showed that hypoimmune-modified iPSCs survived for the duration of the study (16 weeks), while unmodified iPSCs disappeared within two weeks. There was an antibody and T cell response directed toward unmodified cells, but not hypoimmune-modified cells.
• Hypoimmune-modified primary NHP pancreatic islet cells survived 40 weeks (duration of the study) after allogeneic transplantation into an immunocompetent NHP versus less than one week for unmodified primary islet cells.
• Hypoimmune-modified iPSCs were differentiated into pancreatic islet cells. Transplantation of hypoimmune-modified iPSC-derived pancreatic cells into allogeneic diabetic mice with a humanized immune system showed immune evasion after transplantation for the duration of the studies (4 weeks) and amelioration of diabetes and normalization of blood glucose levels.

Presented multiple abstracts at several medical conferences, including AACR, ASGCT, and ISSCR 2023, highlighting both the hypoimmune and fusogen platforms

• ISSCR:
  • Presented preclinical data showing that hypoimmune-modified CD19-directed CAR T cells have the potential to serve as a universal off-the-shelf therapy with long-term durability of response without immunosuppression.
  • Presented preclinical data showing HIP-modified primary pancreatic islet cells alleviate diabetes in humanized mice and avoid immune rejection without immunosuppression.
  • Presented preclinical data showing that intramuscular administration of islet cells in humanized mice does not impact cell function and viability and may serve as a preferred administration route for patients.
  • Presented preclinical data showing in vivo delivery of genetic payloads to human hematopoietic stem/progenitor cells.
• ASGCT:
  • Presented preclinical data demonstrating a novel technique to detect peripheral blood CAR+ T cells.
  • Presented preclinical data demonstrating cell-specific transduction, CAR expression, and target cell killing, which supports the safety of in vivo administration of Sana’s novel CD8-targeted fusosomes for CAR T therapies.
  • Presented multiple process improvements in CD8-targeted fusosome manufacturing that enhance fusosome transduction of resting T cells in vitro and in vivo, including in vitro and in vivo tumor killing.
  • Presented the development of a modular approach to generate fusosomes for targeted gene delivery.
• AACR:
  • Presented preclinical data demonstrating that hypoimmune-modified CAR T cells provide lasting tumor control in immunocompetent allogeneic humanized mice even with tumor re-challenge.
  • Presented preclinical data in a late-breaking poster presentation demonstrating that the increased potency of CD8-targeted fusosomes enhances CAR transgene delivery to resting primary T cells.
  • Presented preclinical data demonstrating the effectiveness of Sana’s fully human CD19 CAR delivered by CD8-targeted fusosomes in tumor killing assays. These fusosomes led to similar levels of tumor control as ex vivo generated CD19 CAR T cells.
  • Presented preclinical data demonstrating increased potency of CD8-targeted fusosomes delivering a CD19 CAR with pre-treatment of resting T cells with IL-7, rapamycin, or both. Pre-treatment with these molecules led to increased anti-tumor efficacy through increased T cell transduction and greater CAR T cell expansion.

Second Quarter 2023 Financial Results

GAAP Results

• Cash Position: Cash, cash equivalents, and marketable securities as of June 30, 2023 were $325.9 million compared to $434.0 million as of December 31, 2022. The decrease of $108.1 million was primarily driven by cash used in operations of $138.1 million and cash used for the purchase of property and equipment of $3.7 million. The decrease in cash was offset by net proceeds of $27.0 million from at the market equity offerings during the six months ended June 30, 2023.
• Research and Development Expenses: For the three and six months ended June 30, 2023, research and development expenses, inclusive of non-cash expenses, were $73.0 million and $140.2 million, respectively, compared to $72.5 million and $145.2 million for the same periods in 2022. The increase of $0.5 million for the three months ended June 30, 2023 compared to the same period in 2022 was primarily due to an increase in clinical development costs, non-cash lease costs for our planned manufacturing facility in Bothell, Washington (the Bothell facility), personnel-related costs, and depreciation expense. These increases were partially offset by a decrease in costs for laboratory supplies, third-party manufacturing costs, and costs related to the previously planned manufacturing facility in Fremont, California (the Fremont facility) that are now included in general and administrative expense. The decrease of $5.0 million for the six months ended June 30, 2023 compared to the same period in 2022 was primarily due to a decline in costs to acquire technology, laboratory supplies, third-party manufacturing, and costs related to the Fremont facility that are now included in general and administrative expense. These decreases were partially offset by increased clinical development costs, personnel-related costs, non-cash lease costs for the Bothell facility, depreciation expense, and other allocated costs. Research and development expenses include non-cash stock-based compensation of $6.7 million and $12.7 million, respectively, for the three and six months ended June 30, 2023, and $7.4 million and $13.1 million, for the same periods in 2022.
• Research and Development Related Success Payments and Contingent Consideration: For the three and six months ended June 30, 2023, we recognized expenses of $26.7 million and $26.8 million, respectively, in connection with the change in the estimated fair value of the success payment liabilities and contingent consideration in aggregate, compared to gains of $17.9 million and $73.4 million for the same periods in 2022. The value of these potential liabilities may fluctuate significantly with changes in Sana’s market capitalization and stock price.
• General and Administrative Expenses: General and administrative expenses for the three and six months ended June 30, 2023, inclusive of non-cash expenses, were $16.6 million and $33.3 million, respectively, compared to $18.3 million and $32.7 million for the same periods in 2022. The decrease of $1.7 million for the three months ended June 30, 2023 compared to the same period in 2022 was primarily due to the write-off of construction in progress costs in 2022 for the Fremont facility, partially offset by an increase in legal fees, non-cash stock-based compensation, and costs related to the Fremont facility, formerly in research and development expense. The increase of $0.6 million for the six months ended June 30, 2023 compared to the same period in 2022 was primarily due to an increase in personnel-related costs including non-cash stock-based compensation, costs related to the Fremont facility, formerly in research and development expense, and legal fees, partially offset by the write-off of construction in progress costs for the Fremont facility.
• Net Loss: Net loss for the three and six months ended June 30, 2023 was $114.0 million, or $0.59 per share, and $196.1 million, or $1.02 per share, respectively, compared to $72.5 million, or $0.39 per share, and $103.9, or $0.56 per share for the same periods in 2022.

Non-GAAP Measures

• Non-GAAP Operating Cash Burn: Non-GAAP operating cash burn for the six months ended June 30, 2023 was $136.5 million compared to $155.4 million for the same period in 2022. Non-GAAP operating cash burn is the decrease in cash, cash equivalents, and marketable securities, excluding cash inflows from financing activities, cash outflows from business development, non-recurring items, and the purchase of property and equipment.
• Non-GAAP General and Administrative Expenses: Non-GAAP general and administrative expenses for the three and six months ended June 30, 2023 was $16.6 million and $33.3 million, respectively, compared to $13.8 million and $28.3 million for the same periods in 2022. Non-GAAP general and administrative expense excludes the write-off of construction in progress costs incurred in connection with the Fremont facility.
• Non-GAAP Net Loss: Non-GAAP net loss for the three and six months ended June 30, 2023 was $87.3 million, or $0.45 per share, and $169.3 million, or $0.88 per share, respectively, compared to $85.9 million, or $0.47 per share, and $172.8 million, or $0.93 per share for the same periods in 2022. Non-GAAP net loss excludes non-cash expenses related to the change in the estimated fair value of contingent consideration and success payment liabilities.

A discussion of non-GAAP measures, including a reconciliation of GAAP and non-GAAP measures, is presented below under “Non-GAAP Financial Measures.”

Non-GAAP Financial Measures

To supplement the financial results presented in accordance with generally accepted accounting principles in the United States (GAAP), Sana uses certain non-GAAP financial measures to evaluate its business. Sana’s management believes that these non-GAAP financial measures are helpful in understanding Sana’s financial performance and potential future results, as well as providing comparability to peer companies and period over period. In particular, Sana’s management utilizes non-GAAP operating cash burn, non-GAAP research and development expense and non-GAAP net loss and net loss per share. Sana believes the presentation of these non-GAAP measures provides management and investors greater visibility into the company’s actual ongoing costs to operate its business, including actual research and development costs unaffected by non-cash valuation changes and certain one-time expenses for acquiring technology, as well as facilitating a more meaningful comparison of period-to-period activity. Sana excludes these items because they are highly variable from period to period and, in respect of the non-cash expenses, provides investors with insight into the actual cash investment in the development of its therapeutic programs and platform technologies.

These are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read in conjunction with Sana’s financial statements prepared in accordance with GAAP. These non-GAAP measures differ from GAAP measures with the same captions, may be different from non-GAAP financial measures with the same or similar captions that are used by other companies, and do not reflect a comprehensive system of accounting. Sana’s management uses these supplemental non-GAAP financial measures internally to understand, manage, and evaluate Sana’s business and make operating decisions. In addition, Sana’s management believes that the presentation of these non-GAAP financial measures is useful to investors because they enhance the ability of investors to compare Sana’s results from period to period and allows for greater transparency with respect to key financial metrics Sana uses in making operating decisions.
