       – Strengthened balance sheet with gross proceeds of approximately $47.6 million from private investment in public equity (PIPE) financing –

SOUTH SAN FRANCISCO, Calif., March 20, 2025 (GLOBE NEWSWIRE) -- Senti Biosciences, Inc. (NASDAQ:SNTI) ("Senti Bio" or the "Company"), a clinical-stage biotechnology company developing next-generation cell and gene therapies using its proprietary Gene Circuit platform, today reported financial results for the fourth quarter of 2024 and provided a summary of recent pipeline and corporate highlights.

"With initial data from the clinical trial of SENTI-202, we are getting a glimpse into the potential profile of our gene circuit-enabled CAR-NK therapy for patients with AML. As we look toward 2025, we anticipate sharing additional data from this exciting trial," said Timothy Lu, MD, PhD, Chief Executive Officer and Co-Founder of Senti Bio. "We are also grateful to have continued support from our investors, including those who participated in our successful PIPE financing in December 2024, and we look forward to demonstrating the potential of our next-generation cell therapies in oncology."

PIPELINE AND CORPORATE HIGHLIGHTS

SENTI-202 for AML: The Company previously announced initial data from its ongoing Phase 1 clinical trial of SENTI-202 (NCT06325748) for the treatment of relapsed/refractory hematologic malignancies including acute myeloid leukemia ("AML").

As announced in December 2024, three AML patients had been treated at the lowest dose level (1.0 billion CAR+ NK cells per dose) and lowest dose schedule (3 doses per cycle) and two achieved complete remission ("CR"), confirmed by bone marrow biopsy, which includes blast reduction and recovery of blood cells to normal ranges. In addition, both patients were assessed as measurable residual disease ("MRD") negative after treatment, which is defined as no detectable cancer cells present in a bone marrow sample by the most sensitive locally available method. As of this month, both patients remain in remission. Across all three patients for which data was announced, SENTI-202 was generally well-tolerated, with an adverse event profile consistent with the use of lymphodepleting chemotherapy in patients with AML.

Raised gross proceeds of $47.6 million in private investment in public equity (PIPE) financing: In early December 2024, the Company announced a $37.6 million PIPE financing, followed by an additional $10.0 million later that month as part of the same financing. The financing, which was led by Celadon Partners, with participation from New Enterprise Associates (NEA), Leaps by Bayer, Nantahala Capital, The Red Hook Fund LP, and other institutional and accredited investors, is expected to extend the Company's financial runway into 2026. The Company plans to use the net proceeds of $45.1 million to fund the continued development of the SENTI-202 program and manufacturing ramp-up, other research and development activities, and for general corporate purposes.

Received CIRM Grant funds for clinical development of SENTI-202: In January 2025, the Company also received an additional $1.5 million from its $8 million grant from the California Institute for Regenerative Medicines ("CIRM") that was first announced in July 2024, bringing the total CIRM amount received by the Company to $6.4 million.

Expanded senior leadership team: In February 2025, the Company announced the addition of strategic hires Jay Cross as Chief Financial Officer and Faraz Siddiqui as Senior Vice President of Technical Operations.

Appointed Fran Schulz and Feng Hsiung to the Board of Directors ("Board"): In December 2024, Fran Schulz was appointed to the Board. She has finance, strategic planning, operations, and transactions expertise in the life sciences industry. She serves as chairperson of the Board's Audit Committee. In March 2025, Feng Hsiung was appointed to the Board and as a member of the Audit Committee. He has extensive business, finance, and investment experience from a career that included investment and portfolio management as well as investment banking.

FOURTH QUARTER AND FULL YEAR 2024 FINANCIAL RESULTS

• Cash and Cash Equivalents: As of December 31, 2024, Senti Bio held cash and cash equivalents of $48.3 million.
• R&D Expenses: Research and development expenses were $7.8 million for the quarter ended December 31, 2024, compared to $9.1 million for the same period in 2023. The decrease was primarily related to a reduction in headcount as the Company streamlined operations to prioritize SENTI-202 in 2024. For the full year of 2024, research and development expenses were $34.4 million.
• G&A Expenses: General and administrative expenses were $8.4 million for the quarter ended December 31, 2024, compared to $9.3 million for the same period in 2023. The decrease was mainly attributed to a reduction in headcount. For the full year of 2024, general and administrative expenses were $26.3 million.
• Net Loss: Net loss was $0.6 million, or $0.67 per basic and diluted share, for the quarter ended December 31, 2024. Net loss for the full-year 2024 was $52.8 million, or $12.03 per share, including non-cash stock-based compensation expense of $1.8 million.

About Senti Bio

Senti Bio is a clinical-stage 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. Senti Bio's wholly-owned pipeline includes off-the-shelf CAR-NK cells, outfitted with Gene Circuits, to target challenging liquid and solid tumor indications. Senti Bio's lead program SENTI-202, a Logic Gated CD33 and/or FLT3-targeting hematologic cancer therapeutic candidate, demonstrated MRD-negative complete remissions in 2 of 3 patients in initial clinical data as of September 19, 2024, with 4+ and 3+ month durability as of December 2, 2024. Senti Bio has also preclinically demonstrated that its Gene Circuits can function in T cells, for example against solid tumor targets. Additionally, Senti Bio has preclinically demonstrated the potential breadth of Gene Circuits in other cell and gene therapy modalities, diseases outside of oncology, and continues to advance these capabilities through partnerships.
