Jounce Therapeutics Announces Results from Pre-Planned Data Review of INNATE Phase 2 Trial of JTX-8064 and Pimivalimab Demonstrating Deep and Durable Responses in Platinum Resistant Ovarian Cancer

Excerpt from the Press Release:

CAMBRIDGE, Mass., March 16, 2023 (GLOBE NEWSWIRE) — Jounce Therapeutics, Inc. (Nasdaq: JNCE), a clinical-stage company focused on the discovery and development of novel cancer immunotherapies and predictive biomarkers, today announced that patients from the INNATE Phase 2 trial in the ovarian cancer combination cohort with platinum resistant ovarian cancer are experiencing deep and durable responses based on a pre-planned informal data review.

The INNATE trial evaluates JTX-8064 as a monotherapy and in combination with the PD-1 inhibitor pimivalimab in patients with advanced solid tumors. JTX-8064, is a humanized IgG4 monoclonal antibody designed to specifically bind to the macrophage receptor Leukocyte Immunoglobulin Like Receptor B2 (LILRB2/ILT4), inhibiting LILRB2 binding with its ligands which may result in reprogramming immune-suppressive macrophages to enhance anti-tumor immunity.

A data review was conducted on March 15, 2023 to assess the potential to achieve proof-of-concept (POC) in the ovarian cancer combination cohort of the INNATE trial. In this cohort, 35 patients with third- and fourth-line platinum resistant ovarian cancer were treated with JTX-8064 and Jounce’s PD-1 inhibitor, pimivalimab. There were five RECIST 1.1 responders, four of which are confirmed, with all five patients remaining on study for over six months with continued tumor reduction over time.
