SOUTH SAN FRANCISCO, Calif., Aug. 15, 2022 /PRNewswire/ -- IDEAYA Biosciences, Inc. (Nasdaq: IDYA), a synthetic lethality focused precision medicine oncology company committed to the discovery and development of targeted therapeutics, provided a business update and announced financial results for the second quarter ended June 30, 2022.
"The IDE397 program is at a key inflection point, and as a wholly-owned program, is uniquely positioned for value accretion as we initiate monotherapy expansion and combination cohorts. Our clinical trial collaboration with Amgen enables clinical evaluation of IDE397 in combination with AMG 193, Amgen's investigational MTA-cooperative PRMT5 inhibitor, a potential first-in-class combination inhibiting two complementary synthetic lethal nodes within the MTAP pathway. The clinical ctDNA molecular response data from the IDE397 monotherapy dose escalation demonstrates target engagement and tumor pharmacodynamic modulation, and provides additional data on clinical activity," said Yujiro S. Hata, President and Chief Executive Officer, IDEAYA Biosciences.
"We look forward to providing the interim Phase 2 clinical data update for darovasertib and crizotinib synthetic lethal combination in first-line and any-line MUM patients in September 2022. This clinical data update will include, confirmed ORR by RECIST, median PFS, median duration-of-response, and an adverse event summary. We will also provide an update on a potential registrational path in MUM, and share observations supporting clinical proof of concept for potential use of darovasertib in the (neo)adjuvant UM setting," continued Mr. Hata.
"We have a pipeline of potential first-in-class synthetic lethality therapeutics advancing toward the clinic. We are targeting an IND in Q4 2022 for IDE161, our PARG inhibitor, for patients having tumors with HRD. In collaboration with GSK, we are targeting first-in-human clinical evaluation in H1 2023 for our Pol Theta Helicase development candidate in combination with niraparib for patients having tumors with HRD, and our Werner Helicase program with GSK continues to be on track for development candidate nomination in 2023," said Michael White, Senior Vice President and Chief Scientific Officer of IDEAYA Biosciences.
