Summary
This study is divided into 2 cohorts of people with primary uveal (ocular) melanoma requiring either internal radiation therapy (plaque brachytherapy) or the removal of the eyeball (enucleation). Within each cohort, participants will randomly assigned (by chance) to receive one of two treatments.
In Cohort 1, participants will either receive neoadjuvant treatment with darovasertib followed by brachytherapy, or immediate brachytherapy.
In Cohort 2, participants will either receive neoadjuvant darovasertib followed by definitive primary local therapy (i.e. plaque brachytherapy, proton beam radiation, or enucleation), or immediate enucleation.
Participants will then receive primary local therapy following neoadjuvant darovasertib.
All participants will be followed for up to 3 years to assess longer term outcomes such as vision and tumour recurrence.
