Binimetinib in Patients With BRAF Fusion-positive Low-grade Glioma or Pancreatic Cancer (Perfume)

Study Purpose

This study is an open-label, parallel, 2-cohort, multicenter, investigator-initiated Phase 2 trial to evaluate the efficacy and safety of binimetinib in patients with advanced or recurrent low-grade glioma or pancreatic cancer harboring BRAF fusion/rearrangement.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
