SOUTH SAN FRANCISCO, Calif., Nov. 10, 2022 (GLOBE NEWSWIRE) -- Senti Biosciences, Inc. (Nasdaq: SNTI) (“Senti Bio”), a biotechnology company innovating next-generation cell and gene therapies using its proprietary gene circuit platform, today reported financial results for the third quarter ended September 30, 2022, and highlighted recent pipeline advances, including an outline for its proposed Phase 1 clinical trial plans for SENTI-202, to include patients with CD33 and/or FLT3 expressing hematologic malignancies including acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). Senti Bio also selected SENTI-301A as the development candidate from its GPC3 targeting solid tumor program. SENTI-301A is a Multi-Armed off-the-shelf chimeric antigen receptor natural killer (CAR-NK) cell therapy candidate designed for the treatment of GPC3 expressing tumors including hepatocellular carcinoma (HCC), the most common form of liver cancer in adults.

In addition, Senti Bio’s data presentation at the Society for Immunotherapy of Cancer (SITC) Annual Meeting outlined continued progress with the solid tumor CAR-NK product candidate SENTI-301A and the SENTI-401 program. Both programs use Senti Bio’s proprietary gene circuit technology to potentially enhance activity against solid tumors by incorporating potent activating CARs and multifunctional cytokines to influence the tumor milieu as well as support enhanced CAR-NK activity. Specifically, SENTI-401 targets carcinoembryonic antigen (CEA) cell adhesion molecule 5 expressing solid tumors, including colorectal cancer (CRC), and also includes a NOT Logic Gate gene circuit to protect CEA expressing healthy cells from potential “on target, off tumor” killing. This Logic Gating strategy is designed to enable selective cytotoxicity of CAR-NK cells against tumor cells while protecting healthy cells.

“I am proud of our continued progress toward the clinic with our CAR-NK cell therapy oncology programs for both hematologic malignancies and solid tumors. With SENTI-202, we believe that we have generated compelling preclinical data demonstrating the killing of primary AML and MDS tumor cells, while maintaining protection of healthy hematopoietic stem cells, to support a clinical trial aimed at both cancer types, and we remain on track to file an IND in 2023,” said Timothy Lu, MD, PhD, Chief Executive Officer and Co-Founder of Senti Bio. “In addition, we recently selected our development candidate, SENTI-301A, which is designed to treat GPC3 positive tumors including HCC, and are on track to file an IND in 2023.”

Lu added, “Our scientists continue to generate exciting data across our pipeline; data from SENTI-301A and SENTI-401 are being highlighted today at the SITC Annual Meeting, and we are extremely excited to preview new data on SENTI-202 at the American Society of Hematology meeting next month. We remain steadfast in our vision of developing smarter medicines based on truly innovative advancements with our gene circuit technology platform.”

RECENT PIPELINE HIGHLIGHTS

CAR-NK Cell Oncology Pipeline and Gene Circuit Platform Highlights:

SENTI-202: A Logic Gated off-the-shelf CAR-NK cell therapy development candidate designed to selectively target and eliminate CD33 and/or FLT3 expressing hematologic malignancies, such as AML and MDS, while sparing the healthy bone marrow.

  • Announced the acceptance of an abstract for presentation at the American Society of Hematology (ASH) meeting in December 2022; preclinical data to highlight the use of Logic Gating gene circuits to target and eliminate AML cells while sparing healthy hematopoietic stem cells.
  • Outlined plans for a proposed Phase 1 clinical trial, including a dose-finding phase in patients with relapsed and/or refractory CD33 and/or FLT3 expressing hematologic malignancies. Disease-specific expansion cohorts would include relapsed and/or refractory AML. Multiple doses of SENTI-202 administration following standard fludarabine/cyclophosphamide (Flu/Cy) lymphodepleting chemotherapy is planned along with a potential to receive multiple cycles. Clinical trial endpoints would evaluate safety and identification of a recommended Phase 2 dose of SENTI-202, as well as efficacy using standard disease-specific response criteria.
  • Manufacturing efforts and GMP facility buildout remain on track towards enabling flexible clinical manufacturing of CAR-NK cells in 2023.
  • An IND application for SENTI-202 is expected to be submitted to the U.S. Food and Drug Administration (FDA) in 2023.

SENTI-301A: A Multi-Armed off-the-shelf CAR-NK cell therapy development candidate designed for the treatment of GPC3 expressing tumors, including HCC.

  • Selected a development candidate, SENTI-301A, based on extensive optimization using Senti Bio’s proprietary screening platform for off-the-shelf CAR-NK cells with potent anti-tumor activity. SENTI-301A uses the following components:
    • Engineered NK cells that target glypican 3 (GPC3), which is highly expressed in 70% to 90% of HCCs and has low or no expression on normal adult tissues.
    • Calibrated release interleukin-15 (crIL-15), a multi-functional immuno-stimulatory payload designed to simultaneously stimulate surrounding immune cells and promote CAR-NK cell expansion, persistence and tumor killing.
  • Preclinical data presented today at the SITC Annual Meeting demonstrates the use of gene circuits to improve the cytotoxicity and persistence of GPC3 targeting CAR-NK cells in treating HCC. Senti Bio’s novel GPC3 targeting activating CAR combined with crIL-15 technology provide the CAR-NK cells multi-arming to enhance persistence and killing activity of the NK cells, and to leverage the endogenous immune system for increased anti-tumor activity. The data presents evidence of robust in vitro and in vivo killing of relevant tumor cells with SENTI-301A.
  • An IND application for SENTI-301A is expected to be submitted to the FDA in 2023

The presentation at the SITC Annual Meeting also includes data from ongoing development of Regulator Dial gene circuits that control expression of crIL-12 in response to FDA-approved small molecules. These data indicate that the Company’s Regulatory Dial gene circuits may be used with an expanded number of FDA-approved drugs to modulate crIL-12 expression, including tamoxifen and grazoprevir, among others. These data give the Regulator Dial the potential for broader applicability beyond GPC3 expressing cancers and thus, the Company is actively exploring the continued development of this gene circuit for product opportunities across a wide range of additional solid tumors.

SENTI-401: A Logic Gated, Multi-Armed off-the-shelf selective CAR-NK cell therapy development program designed to precisely target CEA positive solid tumors (e.g., colorectal, pancreatic and lung cancers) while sparing healthy cells using the NOT Logic Gate.

  • Presented preclinical proof-of-concept data at the SITC Annual Meeting that demonstrates the robust anti-cancer functionality of Logic Gated, Multi-Armed CAR-NK cells against a variety of colorectal cancer models:
    • Evaluated ways to enhance NK cell persistence and function using a combination of crIL-15 and IL-21, a previously undisclosed Multi-Arming combination, resulting in significantly enhanced and durable killing of CEA positive target cells in vitro and in vivo.
    • Long-term anti-tumor responses: a single dose of CEA targeting CAR-NK cells armed with crIL-15+IL-21 resulted in durable anti-tumor activity in human CRC xenograft models that express CEA, including complete tumor regressions.
    • CAR-NK cells equipped with an optimized inhibitory CAR (iCAR) suppressed activating CAR (aCAR)-mediated killing of healthy cells that co-expressed VSIG2-and CEA without diminishing aCAR-mediated anti-tumor activity of CEA expressing tumor cells.
