IDEAYA Announces First-Patient-In for Phase I Clinical Trial to Evaluate Darovasertib Monotherapy in (Neo)Adjuvant Uveal Melanoma
IDEAYA Biosciences has initiated an Investigator Sponsored Trial (IST) in Australia to evaluate darovasertib as a monotherapy for primary, non-metastatic uveal melanoma (UM). Preliminary signs of clinical activity show tumor shrinkage in patients following treatment. With an annual incidence of about 8,700 patients in the US and EU, (neo)adjuvant UM represents an unmet medical need. The trial aims to assess the feasibility and tolerability of darovasertib, following anecdotal evidence of effectiveness. Clinical proof-of-concept data is expected in September 2022.

SOUTH SAN FRANCISCO, Calif., Sept. 6, 2022 /PRNewswire/ -- IDEAYA Biosciences, Inc. (Nasdaq: IDYA), a synthetic lethality focused precision medicine oncology company committed to the discovery and development of targeted therapeutics, announced that it has initiated an Investigator Sponsored Trial, or IST, in coordination with St. Vincent's Hospital, Sydney, to evaluate darovasertib as monotherapy in neo-adjuvant and adjuvant settings in primary, non-metastatic uveal melanoma (UM) patients.
The study, captioned as "Neoadjuvant / Adjuvant trial of Darovasertib in Ocular Melanoma" (NADOM), is being led by principal investigator Professor Anthony Joshua, MBBS, PhD, FRACP, Head Department of Medical Oncology, Kinghorn Cancer Centre, St. Vincent's Hospital in Sydney with participating sites of Alfred Health and the Royal Victorian Eye and Ear Hospital in Melbourne. Pursuant to the protocol, the NADOM study will evaluate darovasertib as monotherapy in eligible adult patients having ocular melanoma to determine the feasibility and tolerability of (neo)adjuvant treatment.
"We are excited to be leading this ground-breaking clinical study treating patients with darovasertib in the neo-adjuvant and adjuvant settings. The concept for this study originated from anecdotal observations in a MUM patient treated with darovasertib who also had an intact primary lesion in the eye, where a reduction in the eye lesion was observed at an initial scan with improvement in visual symptoms," said Professor Anthony Joshua, MBBS, PhD, FRACP, Head Department of Medical Oncology, Kinghorn Cancer Centre, St. Vincent's Hospital Sydney.
"We are observing an early signal of clinical activity in the first patient enrolled in the NADOM study," said Professor Mark Shackleton MBBS, PhD, FRACP, Director of Oncology at Alfred Health and Professor of Oncology, Monash University. "Our coordinated patient care with eye specialists at the Royal Victorian Eye and Ear Hospital on this trial has enabled a potential paradigm-shifting approach to reduce the size of ocular tumors prior to primary treatment, which we hope will lead to better outcomes for patients," continued Professor Shackleton.
"There are currently limited treatment options for patients with uveal melanoma in the pre-metastatic setting. We are pleased to be collaborating with St. Vincent's Hospital in Sydney and with Alfred Health and Royal Victorian Eye and Ear Hospital in Melbourne to explore the potential for darovasertib monotherapy to be impactful for patients with primary uveal melanoma," said Dr. Matthew Maurer, M.D., Vice President, Head of Clinical Oncology and Medical Affairs, IDEAYA Biosciences.
Uveal melanoma is a rare, lethal form of melanoma that arises from melanocytes of the iris, the ciliary body, or most commonly the choroid, with an annual potential incidence of approximately 8,700 patients aggregate in US and Europe. Current approaches for treatment of primary UM includes radiotherapy (plaque brachytherapy or stereotactic radiosurgery) and, for larger tumors, enucleation of the eye, with consequential patient impact including reduced vision, decreased depth perception, diminished social functioning and unsatisfactory cosmesis.
Darovasertib (IDE196) is a potent, selective small molecule inhibitor of protein kinase C (PKC). Mutations in GNAQ or GNA11 (GNAQ/11) have been identified in approximately
In addition to supporting the NADOM study with St. Vincent's Hospital Sydney, IDEAYA is also evaluating the synthetic lethal combination of darovasertib and crizotinib, a small molecule cMET inhibitor, in metastatic uveal melanoma (MUM) in an ongoing Phase 2 clinical trial pursuant to a clinical trial collaboration and drug supply agreement with Pfizer.
IDEAYA is targeting interim Phase 2 clinical results for darovasertib and crizotinib synthetic lethal combination in first-line and any-line MUM patients in September 2022, including clinical efficacy in MUM (e.g., confirmed overall response rate by RECIST, median progression-free survival, median duration of response) and an adverse event summary. The company will also present data supporting clinical proof of concept for potential use of darovasertib in primary (neo)adjuvant UM.
