IDEAYA Announces Results for Darovasertib Phase 2 IST in Neoadjuvant Uveal Melanoma at ASCO and Clinical Update for Phase 2 Company-Sponsored Neoadjuvant Study
- 75% eye preservation rate (9 of 12 enucleation patients)
- ~67% (8 of 12 enucleation patients) observed greater than 30% tumor shrinkage and median tumor shrinkage of 47% by volume change after 6 months
- Company-sponsored Phase 2 Neoadjuvant UM: Over 40 patients enrolled, and for the 8 patients with ≥4-months of darovasertib observed median tumor shrinkage of 72% by volume change and eye preserved for the majority of enucleation patients
- Targeting Type C meeting with the FDA in H2 2024 for guidance on potential registrational trial for darovasertib in neoadjuvant UM setting
- Projected global annual incidence of primary UM is ~8,000 to ~10,000 patients
"The clinical data presented at ASCO provides further validation for the potential of darovasertib in the neoadjuvant UM setting to preserve the eye and to shrink ocular tumors for UM patients," said
"The clinical data presented at ASCO highlights the potential of darovasertib as a neoadjuvant treatment to provide meaningful tumor shrinkage in patients with ocular tumors and spare patients from enucleation, with a manageable AE profile," added
As of the database lock on
The darovasertib monotherapy neoadjuvant treatment had a manageable adverse event (AE) profile with no drug-related serious adverse events observed. Drug-related AEs were predominantly Grade 1 or Grade 2 and 20% of patients reported at least one drug-related Grade 3 adverse event.
The Company is targeting a Type C meeting with the FDA to discuss a potential registrational trial for darovasertib in the neoadjuvant UM setting and a clinical efficacy update from its Phase 2 company-sponsored darovasertib neoadjuvant UM trial in H2 2024. As of
In the 8 patients with 4-months or more of darovasertib treatment as of
The darovasertib program has ongoing enrollment of a potential registrational Phase 2/3 trial in first-line HLA-A2-negative metastatic UM (MUM), and Phase 2 trials in HLA-A2 positive MUM and neoadjuvant and adjuvant UM. Darovasertib received FDA Fast Track designation in MUM and FDA Orphan Drug designation for the treatment of Uveal Melanoma, including MUM. We project the global annual incidence of primary uveal melanoma is approximately 8,000 to 10,000 patients, with the majority of patients in the
