Sapience Therapeutics Announces Poster Presentation on the Immune Activating Function of ST101 at Society for Immunotherapy of Cancer (SITC) 37th Annual Meeting

HARRISON, N.Y., Oct. 12, 2022 /PRNewswire/ -- Sapience Therapeutics, Inc., a clinical-stage biotechnology company focused on the discovery and development of peptide therapeutics to address oncogenic and immune dysregulation that drive cancer, announced today that an abstract describing non-clinical and clinical data supporting the immune activating activity of ST101 has been selected for presentation at the upcoming SITC 37^th Annual Meeting, taking place November 8-12, 2022 in Boston, MA.

Title: "ST101, a peptide antagonist of novel I/O target CEBPβ, reprograms MDSC polarization and decreases tumor-associated Tregs, suggesting an immune component to observed clinical responses" 
Abstract Number: 1173
Location: Poster Hall C 
Date/Time: Thursday, November 10, 2022 – Friday, November 11, 2022, 9am-9pm

The SITC website indicates that all accepted abstracts will be published as a supplement in the Journal for ImmunoTherapy of Cancer (JITC), the society's global, open access, peer-reviewed journal, which will be published on Nov. 7, 2022 at 8 a.m. EST.

ST101, a first-in-class antagonist of C/EBPβ, is currently being evaluated in the Phase 2 portion of an ongoing Phase 1-2 clinical study in patients with advanced unresectable and metastatic solid tumors (NCT04478279). ST101-101 is an open-label, Phase 1-2 dose-finding study designed to determine the safety, tolerability, PK, PD, and proof-of-concept efficacy of ST101 in patients with advanced solid tumors. The study consists of two phases: Phase 1 dose escalation/regimen exploration and Phase 2 dose expansion. In the ongoing Phase 2 dose expansion, Sapience is actively enrolling patients with GBM, metastatic cutaneous melanoma, castration-resistant prostate cancer and locally advanced or metastatic hormone-receptor positive breast cancer. In the Phase 1 portion, ST101 demonstrated clinical proof-of-concept with a durable RECIST 1.1-confirmed partial response (PR) in a patient with cutaneous melanoma and evidence of long-lasting stable disease in several additional patients. In the ongoing Phase 2 dose expansion part of the study, ST101 has demonstrated clinical proof-of-concept with a mRANO-confirmed partial response in a patient with recurrent GBM and evidence of long-lasting stable disease in several additional patients. 

ST101 has been granted Fast Track designation for recurrent GBM and advanced cutaneous melanoma in patients who have disease progression on or after anti-PD-1/anti-PD-L1 therapy, as well as orphan designations from the FDA for advanced melanoma, glioma and AML, and from the European Commission for the treatment of glioma.

Sapience Therapeutics, Inc. is a privately held, clinical-stage biotechnology company focused on discovering and developing peptide therapeutics to address oncogenic and immune dysregulation that drive cancer. Its pipeline of SPEARs™ (Stabilized Peptides Engineered Against Regulation) disrupt intracellular protein-protein interactions, enabling targeting of transcription factors which have traditionally been considered undruggable. Sapience's lead program, ST101, is a first-in-class antagonist of C/EBPβ that has demonstrated clinical proof-of-concept in multiple indications.
