ORIC(R) Pharmaceuticals announces agreement with Cancer Research UK to advance a potential first-in-class cip2a-targeted therapy into clinical development. ORIC-259 is a potential first-in-class small molecule mRNA degrader targeting CIP2A, a previously undruggable target Cancer Research UK to fully fund, sponsor, design, and execute CTA-enabling studies and Phase 1/2 clinical development ORIC retains exclusive option to reacquire rights to ORIC-259 following Phase 1/2 data SOUTH SAN FRANCISCO, Calif. and SAN DIEGO, Oct. 05, 2026 (GLOBE NEWSWIRE) - ORIC Pharmaceuticals, Inc. (Nasdaq: ORIC), a clinical stage oncology company focused on developing and commercializing treatments that address mechanisms of therapeutic resistance, today announced an agreement with Cancer Research UK, one of the world's largest funders of cancer research, to advance a potential first-in-class CIP2A-targeted therapy into clinical development. Under the agreement, Cancer Research UK's Centre for Drug Development (CDD) will fully fund, sponsor, design, and execute CTA-enabling studies and early clinical development of ORIC-259 for patients with cancer. ORIC retains an option to reacquire rights to ORIC-259 following Phase 1/2 data, with Cancer Research UK eligible to receive downstream milestone payments and royalties. Cancerous Inhibitor of PP2A (CIP2A) is a protein that contributes to the development and progression of many cancer types due to its role in protein phosphorylation, mitosis, and DNA damage response. ORIC-259 is a potent, selective, orally bioavailable small molecule degrader of CIP2A mRNA. This potential first-in-class mRNA degrader is designed to modify mRNA splicing to incorporate a premature stop codon, leading to mRNA degradation and loss of CIP2A protein, which is critical for cell proliferation and survival of cancers with homologous recombination deficiency (HRD). Promising preclinical data highlight robust antitumor activity in PARP inhibitor sensitive and resistant settings, indicating broad potential for patients with HRD cancers, and supports the path to clinical development for ORIC-259. "We are excited to partner with Cancer Research UK to advance ORIC-259, a potential first-in-class CIP2A-targeted therapy, into the clinic," said Lori Friedman, PhD, chief scientific officer. "Cancer Research UK's proven expertise and capabilities in developing innovative cancer therapies make it an ideal partner for the program, while this structure allows us to remain disciplined in allocating our internal resources to our late-stage clinical pipeline." "ORIC-259 represents an innovative approach to targeting CIP2A, a protein with significant potential in cancer but one that has proven difficult to drug," said Lars Erwig, Director of the CDD. "We share ORIC's mission to overcome treatment resistance in cancer, and we look forward to applying our expertise to explore new treatment options for patients." About ORIC Pharmaceuticals, Inc.
