Update on SRA737
Cambridge, UK, 12 October 2022 - Sareum Holdings plc (AIM: SAR), a clinical stage biotechnology company developing next generation kinase inhibitors for autoimmune disease and cancer, announces that it has been informed by Sierra Oncology, Inc. ("Sierra") (a subsidiary of GSK plc ("GSK") that it intends to return the rights for SRA737 to the CRT Pioneer Fund LP ("CPF") .
SRA737, a clinical-stage oral, selective Checkpoint kinase 1 inhibitor that targets cancer cell replication and DNA damage repair mechanisms, was discovered and initially developed by scientists at The Institute of Cancer Research in collaboration with Sareum, with funding from Sareum and Cancer Research UK.
Sareum will discuss actively with CPF the potential options for future development opportunities for SRA737 and evaluate its next steps accordingly.
CPF acquired worldwide commercial rights to the programme in 2013 as part of a co-development agreement with Sareum. SRA737 was licensed by CPF to Sierra in September 2016. Sierra progressed SRA737 through Phase 1/2 clinical development and, at the 2019 ASCO Annual meeting, reported positive preliminary efficacy and safety data from two clinical trials evaluating SRA737 as a monotherapy and in combination with chemotherapy. In addition, preclinical data have been reported that indicate triple drug combinations involving SRA737 may show great promise against hard-to-treat cancers. Sierra has not progressed the asset beyond the Phase 1/2 clinical trial.
Sierra was acquired by GSK in July 2022.
Dr Tim Mitchell, CEO of Sareum, commented:
"We continue to believe that SRA737 has great potential in several oncology applications, and Sareum now has the opportunity to be involved in planning its future development, supported by the positive clinical studies previously undertaken by Sierra.
"Sareum has a strong pipeline of kinase inhibitors on the threshold of clinical development. Subject to regulatory approval, we plan to advance our lead candidate SDC-1801 into clinical development shortly, a significant milestone for our business. With a strong pipeline and increased clinical validation around the JAK kinase space, we are optimistic about the potential of this drug class, both for patients and commercially."
