SynKIR-110

PHILADELPHIA, Nov. 3, 2023 /PRNewswire/ -- Verismo Therapeutics, a clinical-stage CAR-T company developing novel KIR-CAR platform technology today announced that it will be presenting at the upcoming Society for Immunotherapy of Cancer 38th Annual Meeting (SITC 2023), to be held in San Diego and virtually November 1-5, 2023. Presentation Details Title: Preclinical potency assessment of SynKIR-110, a mesothelin-specific KIR-CAR T cell therapy for mesothelioma Abstract Number: 321 Date and Time: Friday, November 3rd: 12:00-1:30 p.m. and 5:10-6:40 p.m. Presenting Authors: Dr. Jun Xu, PhD & Dr. Laura Johnson, PhD Description: We conducted in vivo potency studies to assess the impact of the engineered T cell dose of the first mesothelin (MSLN)-specific KIR-CAR T cell therapy (SynKIRTM-110) in an NSG mouse xenograft model of human mesothelioma. Our data demonstrate for the first time that anti-tumor efficacy of SynKIRTM-110 is dose-dependent with greater potency compared with MSLN-41BBz CAR T cells previously evaluated in the clinic. This enhanced potency of SynKIRTM-110 was observed both at the primary tumor site and metastatic sites as demonstrated by histopathologic analysis. This increased potency did not impact any serum markers of toxicity, which remained the same regardless of CAR/KIR-CAR treatments. This data supports further clinical development of SynKIRTM-110 in patients with advanced solid tumors. SynKIRTM-110 is currently being investigated in a Phase I clinical trial STAR-101 (NCT05568680). About the KIR-CAR Platform The KIR-CAR platform is a dual-chain CAR T cell therapy and has been shown in preclinical animal models to be capable of maintaining antitumor T cell activity even in challenging solid tumor environments. DAP12 acts as a novel costimulatory molecule for T cells using additional T cell stimulating pathways, further sustaining chimeric receptor expression and improving KIR-CAR T cell functional persistence. This continued T cell function and persistence can lead to ongoing regression of solid tumors in preclinical models, including those resistant to traditional CAR T cell therapies. The KIR-CAR platform is being investigated in combination with additional emerging technologies. About Verismo Therapeutics Verismo Therapeutics is a pioneer in dual-chain KIR-CAR technology, with its lead asset SynKIR™-110 undergoing first-in-human clinical trial. Verismo is the only company developing the KIR-CAR platform, a modified NK-like receptor designed to improve persistence and efficacy against aggressive solid tumors. The KIR-CAR platform technology was developed specifically for advanced solid tumors, an area of high unmet medical need.

Company makes a significant stride toward new treatments for ovarian cancer, pleural mesothelioma, and cholangiocarcinoma PHILADELPHIA, Sept. 6, 2023 /PRNewswire/ -- Verismo Therapeutics, a clinical-stage CAR-T company developing novel KIR-CAR platform technology invented at and licensed from the University of Pennsylvania ("Penn"), today announced that a first patient has been dosed in their STAR-101 clinical trial to study the SynKIR-110 product in individuals with advanced ovarian cancer, mesothelioma, and cholangiocarcinoma. The Phase 1 clinical trial, designed to evaluate the safety, feasibility, and potential activity of SynKIR-110, represents a crucial step forward in improving treatment options in patients with mesothelin-expressing solid tumors. STAR-101 (NCT05568680) is a first-in-human trial that aims to assess the safety, feasibility, and potential activity of a single intravenous (IV) dose of the SynKIR-110 product, which is comprised of autologous T cells transduced with a mesothelin-targeted KIR-CAR. By targeting mesothelin-expressing ovarian cancer, mesothelioma, and cholangiocarcinoma, SynKIR-110 holds potential for creating a new treatment option for these challenging malignancies. "This represents a significant milestone for our company and demonstrates the commitment of our team to address the critical need for additional treatment options for patients with mesothelin-expressing solid tumors," said Dr. Bryan Kim, Co-Founder and CEO of Verismo Therapeutics. "We're proud to work with the distinguished team at Penn to take our SynKIR-110 treatment out of the lab and to the patients with unmet medical needs." The STAR-101 clinical trial will encompass an intervention period, during which subjects will receive non-myeloablative lymphodepleting chemotherapy followed by a single infusion of SynKIR-110, as well as a 12-month follow-up period. For more information on the STAR-101 clinical trial, please visit ClinicalTrials.gov - NCT05568680. "We are excited to initiate this Phase 1 clinical trial of SynKIR-110, which, based on preclinical testing in relevant animal models, holds promise as a potential new therapeutic for patients with advanced ovarian cancer, cholangiocarcinoma, and mesothelioma," said Dr. Janos L. Tanyi, an associate professor of Obstetrics and Gynecology in the Perelman School of Medicine at the University of Pennsylvania and a principal investigator for the trial, "By leveraging the power of autologous T cells transduced with Mesothelin KIR-CAR, we hope to enhance treatment options and ultimately improve outcomes for patients facing these challenging malignancies."

This continued T cell function and persistence can lead to ongoing regression of solid tumors in preclinical models, including those resistant to traditional CAR T cell therapies. The KIR-CAR platform is being investigated in combination with many additional emerging technologies, such as in vivo gene engineering, advanced cell manufacturing and reprogramming, combinational therapies, and even allogeneic cellular therapies to potentially provide the next-generation multimodal targeted immunotherapy for patients in need.
