SOUTH SAN FRANCISCO, Calif., March 21, 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 fourth quarter and full year ended December 31, 2023.

“In 2023, we achieved several critical milestones including clearing our first Investigational New Drug application (“IND”) for SENTI-202, entering into a strategic collaboration agreement with Celest Therapeutics for the clinical development of SENTI-301A to treat solid tumors in China, and establishing a manufacturing partnership with GeneFab that will support the manufacturing of our oncology programs,” said Timothy Lu, MD, PhD, Chief Executive Officer and Co-Founder of Senti Bio. “We also made strategic decisions to focus our resources on advancing SENTI-202 in the U.S. and SENTI-301A in China through our partnership with Celest, with the goal of bringing new treatments to patients.”

Dr. Lu continued, “We will continue to advance our pipeline programs to demonstrate the potential of Gene Circuits including the clinical-scale manufacturing of chimeric antigen receptor natural killer (“CAR-NK”) cells. Additionally, we are continuing our efforts to develop next-generation cell and gene therapies in areas outside of oncology through our collaborations with Spark Therapeutics and BlueRock Therapeutics.”


Prioritization of clinical programs: In January 2024, Senti Bio announced plans to streamline its business operations and prioritize the clinical development of SENTI-202, a potential first-in-class, off-the-shelf Logic Gated CAR-NK investigational cell therapy for the treatment of acute myeloid leukemia (“AML”). Additionally, the Company will continue to support the clinical development activities of SENTI-301A for the treatment of advanced glypican 3 (“GPC3”)-expressing hepatocellular carcinoma (“HCC”) in China through its partnership with Celest Therapeutics (Shanghai) Co. Ltd (“Celest”). Strategic steps included the scaling back of all other research and development initiatives while continuing to support ongoing partnerships with Spark Therapeutics and BlueRock Therapeutics. The Company expects that these resource allocation efforts, combined with other expected receivables, will extend its cash runway into the first quarter of 2025.


SENTI-202 for AML: In December 2023, Senti Bio announced the IND application for SENTI-202 was cleared by the U.S. Food and Drug Administration (“FDA”). The Phase 1 clinical trial will focus on relapsed/refractory AML patients in the U.S. and Australia. The Company anticipates the following from the Phase 1 clinical trial:

  • First patient dosed in the second quarter of 2024
  • Initial efficacy data by year-end 2024
  • Initial durability data in 2025

SENTI-301A for HCC: In November 2023, Senti Bio announced a strategic collaboration agreement with Celest, a China-based biotechnology company, for the clinical development of SENTI-301A to treat solid tumors in China. Celest plans to enroll patients initially through a pilot trial in mainland China and expects to dose the first patient in the second quarter of 2024.   SENTI-301A is a calibrated release (cr) IL-15 multi-armed off-the-shelf CAR-NK cell therapy designed for the treatment of GPC3-expressing tumors, including HCC, the most common type of primary liver cancer.
