SOUTH SAN FRANCISCO, Calif., Nov. 14, 2024 (GLOBE NEWSWIRE) -- Senti Biosciences, Inc. (Nasdaq: SNTI) ("Senti Bio” or the "Company”), a biotechnology company developing next-generation cell and gene therapies using its proprietary Gene Circuit platform, today reported financial results for the third quarter of 2024 and provided a summary of recent pipeline and corporate highlights.

"Over the past quarter, we have continued to execute on our clinical milestones and look forward to sharing initial results from the clinical trial of SENTI-202 before 2024 year-end,” said Timothy Lu, MD, PhD, Chief Executive Officer and Co-Founder of Senti Bio. "As we look toward 2025, we anticipate sharing additional data from this trial including initial durability data and we look forward to continue demonstrating the potential of our technology in our next-generation cell therapies in oncology.”

PIPELINE AND CORPORATE HIGHLIGHTS

SENTI-202 for Acute Myeloid Leukemia ("AML”): The Company announced that patient dosing has commenced, and is ongoing, in the Phase 1 clinical trial of SENTI-202 (NCT06325748) for the treatment of relapsed/refractory hematologic malignancies including AML. The Phase 1 trial focuses on patients with relapsed/refractory AML in the U.S. and Australia. Initial safety and efficacy data readout remains on-track by year-end 2024 and initial durability data is expected to follow in 2025.

CIRM Grant Commencement for Clinical Development of SENTI-202: Through November 2024, Senti Bio has received $4.9 million of an $8 million grant from the California Institute for Regenerative Medicines ("CIRM”) that was first announced in June 2024.

SENTI-301A for HCC: Senti Bio is developing SENTI-301A to treat solid tumors in China through a strategic collaboration with Celest Therapeutics (Shanghai) Co. Ltd ("Celest”). Celest plans to enroll patients initially in a pilot trial in mainland China and expects to dose the first patient in the fourth quarter of 2024.

SELECTED THIRD QUARTER 2024 FINANCIAL RESULTS

• Cash and Cash Equivalents: As of September 30, 2024, Senti Bio held cash and cash equivalents of $10.5 million. Subsequent to quarter-end, the Company received $2.5 million, the second tranche of an $8 million grant from CIRM, for achieving a CIRM operational milestone in August 2024.
• R&D Expenses: Research and development expenses were $8.7 million for the quarter ended September 30, 2024, compared to $9.1 million for the same period in 2023. The decrease year over year was primarily related to a reduction in headcount offset by an increase in manufacturing costs to support development of Senti Bio's wholly-owned programs.
• G&A Expenses: General and administrative expenses were $6.2 million for the quarter ended September 30, 2024, compared to $9.4 million for the same period in 2023. The decrease year over year was mainly attributed to a reduction in headcount.
• Net Loss: Net loss was $28.9 million, or $(6.31) per basic and diluted share, for the quarter ended September 30, 2024.

Senti Bio plans to participate in the following scientific conferences in the near future:

• Immunotherapy Bridge 2024

Senti Bio is a biotechnology company developing a new generation of cell and gene therapies for patients living with incurable diseases. To achieve this, Senti Bio is leveraging a synthetic biology platform called Gene Circuits to create therapies with enhanced precision and control. These Gene Circuits are designed to precisely kill cancer cells, spare healthy cells, increase specificity to target cells and control the expression of drugs even after administration. The Company's wholly-owned pipeline utilizes off-the-shelf CAR-NK cells, outfitted with Gene Circuits, to target challenging liquid and solid tumor indications. Senti Bio has also preclinically demonstrated the potential breadth of Gene Circuits in other modalities, diseases outside of oncology, and continues to advance these capabilities through partnerships with Spark Therapeutics and BlueRock Therapeutics.
