ClinConnect Summary

The clinical trial titled "Palbociclib and Binimetinib in RAS-Mutant Cancers" is investigating how effective a combination of two medications, palbociclib and binimetinib, can be for treating certain types of cancers that have specific changes in their DNA known as RAS mutations. This trial focuses on patients with cancers such as low-grade serous ovarian cancer and pancreatic cancer, among others. The goal is to see if this combination can help delay cancer growth and improve survival without progression for these patients.

To be eligible for this trial, participants generally need to have a confirmed diagnosis of a RAS-mutant cancer and must have previously been enrolled in another study (EAY191). Key criteria include having a specific type of mutation in their tumor, being able to undergo a biopsy, and not having received certain prior treatments. Participants can expect regular monitoring and treatment with the study medications, and their progress will be closely observed. It's important to note that this trial is currently recruiting patients aged 18 and older, and it specifically excludes individuals with certain medical conditions or recent treatments that could interfere with the study.

Eligibility criteria

• Inclusion Criteria:
• • Patient must have enrolled onto EAY191 and must have been given a treatment assignment to ComboMATCH to EAY191-A3 based on the presence of an actionable mutation as defined in EAY191.
