IDEAYA Announces First-Patient-In for Company-Sponsored Phase 2 Clinical Trial Evaluating Darovasertib in (Neo)Adjuvant Uveal Melanoma
- None.
- None.
- Dosed a first patient in a company-sponsored global Phase 2 clinical trial evaluating darovasertib as neoadjuvant and adjuvant therapy in primary uveal melanoma (UM)
- Preliminary clinical activity observed in primary UM, including tumor shrinkage in 9 of 9 patients following neoadjuvant therapy with darovasertib as monotherapy or in combination with crizotinib, two of whom were spared enucleation and preserved vision
- Targeting clinical data update in the fourth quarter of 2023 from the ongoing NADOM IST evaluating single-agent darovasertib as neoadjuvant therapy in primary UM patients
- (Neo)adjuvant UM has no approved systemic therapies with an annual incidence of ~8,700 patients and estimated prevalence of ~100,000 patients aggregate in the
U.S. andEurope
"We are excited to dose our first patient in this Phase 2 clinical trial. Our recently reported preliminary clinical data in the neoadjuvant setting showed compelling evidence of anti-tumor activity – with observed tumor shrinkage in 9 patients, including two patients who were able to avoid enucleation. These data support further clinical evaluation of darovasertib to determine its potential as a neoadjuvant and adjuvant therapy," said Dr. Darrin Beaupre, Chief Medical Officer, IDEAYA Biosciences.
"Treatment with darovasertib as a neoadjuvant therapy provides an opportunity to save the patient's eye by avoiding enucleation or to reduce the tumor in the eye and enable treatment with less radiation to preserve vision. As an adjuvant therapy, the goal is to potentially extend recurrence free survival,", said Sreenivasa R. Chandana, M.D., Ph.D., Medical Oncologist at The Cancer & Hematology Centers in
IDEAYA's Phase 2 clinical trial, designated as IDE196-009 (NCT05907954), is evaluating darovasertib as monotherapy in (neo)adjuvant uveal melanoma with potential near-term clinical neoadjuvant endpoints such as eye preservation for large ocular tumors and reduction in radiation dose and/or vision preservation for small or medium ocular tumors.
Pursuant to the clinical protocol, neoadjuvant treatment of primary UM patients will occur prior to a standard-of-care primary interventional treatment – typically enucleation or radiation therapy. One cohort of UM patients with large tumors will be treated with single-agent darovasertib until maximum benefit or six months, at which time they will undergo a primary interventional treatment. The neoadjuvant endpoint for this large-sized tumor cohort is eye preservation. For example, a patient who would otherwise have undergone enucleation would instead be eligible for radiation treatment. Another neoadjuvant cohort of UM patients with small or medium tumors will be treated with single-agent darovasertib until maximum benefit or six months, at which time they will undergo a primary interventional treatment such as radiation therapy. Neoadjuvant endpoints for this small- or medium-sized tumor cohort include reducing the radiation dose that the patient receives, relative to the radiation dose they would have otherwise received without the neoadjuvant treatment, and functional vision preservation.
In the adjuvant setting, each of the two neoadjuvant cohorts will be treated with single-agent darovasertib for up to six months as follow-up adjuvant therapy after the primary interventional treatment. The adjuvant endpoints for this portion of the clinical trial include recurrence free survival and useful vision.
