– Dose-finding clinical trial in China designed to evaluate safety and preliminary anti-tumor activity of SN301A (SENTI-301A manufactured in China) in hepatocellular carcinoma (“HCC”) –
SOUTH SAN FRANCISCO, CA, USA I December 16, 2024 I 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 the first patient has been dosed in the pilot trial of SN301A in HCC in mainland China in collaboration with Celest Therapeutics (Shanghai) Co. Ltd (“Celest”). SN301A utilizes the anti-GPC3 + crIL-15 (each as defined below) SENTI-301A Gene Circuit developed by Senti Bio and refers to the chimeric antigen receptor natural killer (“CAR-NK”) product candidate manufactured by Celest in China.
Through this collaboration, Celest is leading clinical development, operations and manufacturing of SN301A with technical, strategic and clinical input from Senti Bio. The clinical trial is designed to evaluate safety, pharmacokinetics and preliminary anti-tumor activity of SN301A and will include patients with advanced glypican 3 (“GPC3”)-expressing HCC across multiple dose cohorts. The study endpoints include safety assessments for adverse events and dose limiting toxicities, as well as efficacy analyses using standard response criteria for liver cancer.
“Today’s announcement is a significant demonstration of the progress in our strategic partnership with Celest to advance the clinical development of SENTI-301A, our solid tumor pipeline product candidate in China,” said Timothy Lu, MD, PhD, Chief Executive Officer and Co-Founder of Senti Bio. “We are proud of the rapid development to date, and value how our partnership with the Celest team is playing an important role in bringing Senti Bio’s Gene Circuit technology to patients who have limited or no therapeutic options today. We are excited by the recent positive initial clinical data from our first Gene Circuit enabled cell therapy SENTI-202 in blood cancer, and the potential to expand our platform to treat solid tumors with high unmet clinical needs.”
“We are thrilled to share this progress in the clinical development of SN301A. In successfully initiating this trial, we are now seeing the potential of integrating Senti’s novel Gene Circuit technology to our proprietary NK cell manufacturing and clinical operations expertise,” said Erdong Hua, Chairman of Celest and Managing Partner of 6 Dimensions Capital. “Importantly, as the second leading cause of cancer-related death in Asia, liver cancer remains a large health threat in China. Statistically, over 40 percent of global HCC cases are reported in China, underscoring the significant unmet need that we hope SN301A may help address.”
Additionally, Celest and Senti Bio have the option to expand clinical development of SN301A to Hong Kong, Macau and Taiwan. Senti Bio will retain all development and commercialization rights outside of mainland China, Hong Kong, Macau and Taiwan for SENTI-301A.
About the SN301A Clinical Trial
The safety and efficacy of SN301A is being evaluated in an investigator-initiated open-label, single-center study (NCT06652243) in adult patients with advanced GPC3-expressing HCC. Three dose levels of SN301A will be administered in cycles, each comprising of 3 weekly doses (Days 0, 7, 14) during a 28-day treatment cycle following a standard lymphodepletion conditioning regimen of fludarabine and cytarabine. Patients may continue to receive multiple cycles of treatment based on their safety and efficacy results.
About SENTI-301A/SN301A
SENTI-301A is a multi-armed off-the-shelf healthy donor derived CAR-NK cell therapy designed for the treatment of GPC3 expressing tumors. The engineered NK cells target the GPC3 antigen, which is highly expressed in 70% to 90% of HCCs and has low or no expression on normal adult tissues. Additionally, SENTI-301A incorporates the 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. Senti Bio has shown comprehensive preclinical data demonstrating robust in vitro and in vivo killing of relevant tumor cells with SENTI-301A. This program, in collaboration with Celest, is being developed in China as SN301A. SN301A utilizes the same Gene Circuit as SENTI-301A and refers to the CAR-NK product manufactured by Celest in China.
About Senti Bio
Senti Bio is a clinical-stage biotechnology company developing a new generation of cell and gene therapies for patients living with incurable diseases. To achieve this, Senti Bio is leveraging a synthetic biology platform called Gene Circuits to create therapies with enhanced precision and control. These Gene Circuits are designed to precisely kill cancer cells, spare healthy cells, increase specificity to target cells and control the expression of drugs even after administration. Senti Bio’s wholly-owned pipeline includes off-the-shelf CAR-NK cells, outfitted with Gene Circuits, to target challenging liquid and solid tumor indications. Senti Bio’s lead program SENTI-202, a Logic Gated CD33 and/or FLT3-targeting hematologic cancer therapeutic candidate, demonstrated complete remissions in 2 of 3 patients in initial clinical data as of September 19, 2024. Senti Bio has also preclinically demonstrated that its Gene Circuits can function in T cells. Additionally, Senti Bio has preclinically demonstrated the potential breadth of Gene Circuits in other cell and gene therapy modalities, diseases outside of oncology, and continues to advance these capabilities through partnerships with Roche/Spark Therapeutics and Bayer/BlueRock Therapeutics.
About Celest
Celest was founded to develop intelligent CAR-immune cell therapy for effective treatment of challenging solid tumors. Celest technology platforms employ a suite of in-house developed immunological technologies, including platforms to screen for tumor microenvironment (“TME”) induced immune cell enrichment, trafficking and persistence. In parallel, the platforms also identify and optimize CAR-NK cell signaling domains using high-throughput methods including pooled library screenings. Incubated by 6 Dimensions Capital and 120 Capital with operations in Shanghai, China, Celest is building next-generation innovative cell therapy products with full-fledged capabilities from early R&D, cell manufacturing to clinical development and commercialization.
