– First patient in Phase 1 clinical trial expected to be treated in Q2 2024 –

– Initial clinical efficacy data expected by year-end 2024 and durability data expected in 2025 –

– SENTI-202 is a potential first-in-class off-the-shelf CAR-NK cell therapy using Logic Gated Gene Circuits to selectively target cancer cells while sparing healthy bone marrow cells –

SOUTH SAN FRANCISCO, Calif., Dec. 22, 2023 (GLOBE NEWSWIRE) -- Senti Biosciences, Inc. (Nasdaq: SNTI) (“Senti Bio”), a clinical stage biotechnology company developing next-generation cell and gene therapies using its proprietary Gene Circuit platform, today announced that it received clearance of its Investigational New Drug (IND) application from the U.S. Food and Drug Administration (FDA) for SENTI-202, an off-the-shelf chimeric antigen receptor natural killer (CAR-NK) cell therapy product candidate designed to selectively target and eliminate CD33 and/or FLT3 expressing hematologic malignancies while sparing healthy bone marrow cells.

The Company plans to initiate a Phase 1 clinical trial of SENTI-202 in 2024 in multiple sites in the United States and Australia, and expects to treat the first patient in the second quarter of 2024. The dose finding trial will evaluate two dose levels, either 1 or 1.5 billion SENTI-202 cells, administered after lymphodepleting conditioning in adult patients with relapsed or refractory (r/r) CD33 and/or FLT3 expressing hematologic malignancies, including acute myeloid leukemia (AML). Initial dosing will consist of three doses administered weekly following lymphodepletion, with the option to receive continuation cycles of lymphodepletion and SENTI-202 cells based on safety and efficacy data.

“Clearance of our IND application for SENTI-202 is a tremendous milestone and marks an important achievement for Senti as we transition to a clinical-stage therapeutics company,” said Timothy Lu, MD, PhD, Chief Executive Officer and Co-Founder of Senti Bio. “Our team has dedicated immense time and resources to developing our Gene Circuit technology from an initial synthetic biology hypothesis to what is now a tangible product for cancer patients. We look forward to initiating Senti’s first clinical trial and continuing our strong momentum into next year.”
