Jounce Therapeutics earns clinical milestone payment under the CCR8 exclusive license agreement with Gilead Sciences, Inc.

CAMBRIDGE, Mass., Nov. 02, 2022 (GLOBE NEWSWIRE) -- Jounce Therapeutics, Inc. (NASDAQ: JNCE), a clinical-stage company focused on the discovery and development of novel cancer immunotherapies and predictive biomarkers, announced today earning a $15.0 million clinical milestone payment from Gilead Sciences, Inc. (NASDAQ: GILD) under the exclusive license agreement for GS-1811, an anti-CCR8 antibody for which Gilead has exclusive rights to develop and commercialize. GS-1811 (formerly JTX-1811) is designed to selectively deplete immunosuppressive tumor-infiltrating T regulatory (TITR) cells in the tumor microenvironment.

Under the terms of the September 2020 agreement, Gilead invested $35.0 million in Jounce’s common stock and made an $85.0 million upfront payment to Jounce. Jounce led the development of JTX-1811 through IND clearance, after which Gilead obtained the sole right to develop and commercialize the program. After receiving this $15.0 million milestone payment, Jounce may receive up to an additional $645.0 million in future clinical, regulatory and commercial milestone payments and will also be eligible to receive royalties ranging from high single digit to mid-teens based upon worldwide sales. Any milestone or royalty paid to Jounce is subject to certain reductions as described in the license agreement.
