Robust SENTI-202 clinical data presented at ASH 2025 demonstrated deep, MRD-negative, durable complete remissions and a favorable safety profile
Company planning for rapid advancement of SENTI-202 into R/R AML pivotal study and evaluating indication expansion to include newly diagnosed AMLandpediatric AML; Preparing for FDA discussions in the first half of 2026
SENTI-202 has received Regenerative Medicine Advanced Therapy (RMAT) designation, which may enable an expedited development and review process
SOUTH SAN FRANCISCO, Calif., Feb. 11, 2026 (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 the completion of enrollment in its Phase 1 clinical trial evaluating SENTI-202, a first-in-class CD33/FLT3-targeting Logic Gated CAR NK cell therapy, in patients with relapsed or refractory acute myeloid leukemia (R/R AML).
“The completion of enrollment in our Phase 1 trial represents a significant clinical milestone for our SENTI-202 program,” said Kanya Rajangam, M.D., Ph.D. Chief Medical Officer at Senti Bio. “Importantly, the encouraging clinical data from this study provide a strong foundation as we actively design our pivotal program for SENTI-202 in AML, as well as potential indication expansion and later-stage clinical development. We look forward to having productive discussions and working closely with the FDA in the first half of this year to discuss the next phase of development for our RMAT-designated program.”
Completion of enrollment follows the Company’s recent presentation of positive clinical data from the study at theAmerican Society of Hematology (ASH) Annual Meeting, where SENTI-202 demonstrated deep, MRD-negative, durable complete remissions and a favorable safety profile in a heavily pretreated R/R AML patient population.
With enrollment now complete, the Company plans to have discussions with the U.S. Food and Drug Administration in the first half of 2026 regarding the potential for a pivotal, registration program of SENTI-202 in R/R AML as well as the evaluation of additional indications including newly diagnosed AML and pediatric AML.
SENTI-202 has received Regenerative Medicine Advanced Therapy (RMAT) designation, which may enable an expedited development and review process.
Information about SENTI-202’s Phase 1 clinical trial is publicly available and can be referenced on ClinicalTrials.gov under identifierNCT06325748.
About SENTI-202SENTI-202 is the first Logic Gated off-the-shelf CAR-NK cell therapy product candidate designed to selectively target and eliminate CD33 and/or FLT3 expressing hematologic malignancies, such as AML and myelodysplastic syndrome (MDS), while sparing healthy bone marrow cells. SENTI-202 has three main components. First, SENTI-202 contains an OR GATE, which is an activating CAR that recognizes and kills CD33 and FLT3 expressing cells. By targeting either or both of these antigens, SENTI-202 is designed to effectively kill both leukemic blasts (that largely express CD33) and leukemic stem cells (that predominantly express FLT3), which constitute a difficult-to-eradicate reservoir of AML disease. Second, SENTI-202 contains a NOT GATE, which is an inhibitory CAR that is designed to recognize EMCN selectively expressed on healthy hematopoietic stem and progenitor cells and protect those healthy cells from being killed even if they express CD33 and/or FLT3, thus potentially widening the therapeutic window. Third, SENTI-202 contains calibrated-release IL-15, which is designed to significantly increase cell persistence, expansion and activity of both the CAR-NK cells and host immune cells. The NK cells used to construct SENTI-202 are sourced from selected healthy adult donors, manufactured, cryopreserved and available off-the-shelf for use as needed. Senti Bio is currently enrolling adult patients with R/R CD33 and/or FLT3 expressing heme malignancies in a Phase 1 clinical trial for SENTI-202, which can be a potential first-in-class allogeneic treatment for AML/MDS patients.
The U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) and Regenerative Medicine Advanced Therapy (RMAT) designation to SENTI-202 for the treatment of relapsed/refractory hematologic malignancies including AML.
About Senti Bio
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 its synthetic biology platform to engineer Gene Circuits into new medicines with enhanced precision and control. These Gene Circuits are designed to precisely kill cancer cells, to spare healthy cells, to increase specificity to target tissues, and/or to be controllable even after administration. The Company’s wholly-owned pipeline comprises cell therapies engineered with Gene Circuits to target challenging liquid and solid tumor indications. Senti’s Gene Circuits have been shown preclinically to work in both NK and T cells. Senti Bio has also preclinically demonstrated the potential breadth of Gene Circuits in other modalities and diseases outside of oncology, and continues to advance these capabilities through partnerships.
