SOUTH SAN FRANCISCO, Calif., May 01, 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 announced that Kanya Rajangam, MD, PhD, President, Head of R&D and Chief Medical Officer participated in a Virtual Investor "What This Means" segment.

As part of the segment, Dr. Rajangam discussed the recently announced additional positive preliminary data from a Phase 1 clinical trial of SENTI-202, a potential first-in-class off-the-shelf Logic Gated selective CD33 OR FLT3 NOT EMCN chimeric antigen receptor natural killer (CAR-NK) investigational cell therapy, for the treatment of relapsed/refractory (R/R) hematologic malignancies including acute myeloid leukemia ("AML").

The Virtual Investor "What This Means" segment featuring Senti Bio is now available here.

About SENTI-202

SENTI-202 is a First-in-Class Off-the-Shelf Logic Gated Selective CD33 OR FLT3 NOT EMCN 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 (providing a "kill" signal), which is an activating CAR that recognizes CD33 and/or FLT3. By targeting either or both of these antigens, SENTI-202 is designed to effectively kill both leukemic blasts and leukemia stem cells, which constitute a difficult-to-eradicate reservoir of AML disease. Second, SENTI-202 contains a NOT GATE (providing a "protect" signal), which is an inhibitory CAR that is designed to recognize healthy cells and protect those healthy cells from being killed, even if they were to express CD33 and/or FLT3, thus potentially widening the therapeutic window. Third, SENTI-202 contains calibrated-release IL-15 (providing an "enhance" signal), 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 manufacture SENTI-202 are sourced from selected healthy adult donors. 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 off-the-shelf treatment for AML/MDS patients.

Senti Bio has published SENTI-202 preclinical data demonstrating the potential of Logic Gated CAR-NK cell therapy for the treatment of AML.

About AML

AML is a cancer of the blood and bone marrow and is the most common type of acute leukemia in adults. It is estimated there were 20,800 new cases of AML in the United States in 2024. The five-year survival rate for these patients is approximately 30%. AML is currently treated with chemotherapy, targeted therapies, and/or allogeneic or autologous stem cell transplant. For patients with R/R AML, there are few treatment options and median overall survival is typically approximately five months.

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 is comprised of 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.
