Brief Summary
This is a Phase 2, multi center, open-label study to evaluate the safety and efficacy of Type II RAF (tovorafenib) in pediatric participants with low-grade glioma or advanced solid tumors. Qualifying genomic alterations will be identified through molecular assays as routinely performed at Clinical Laboratory Improvement Amendments (CLIA) of 1988 or other similarly certified laboratories prior to enrollment into any of the arms. The study will consist of a screening period, a treatment period, a long-term extension phase, end of treatment (EOT) visit(s), a safety follow-up visit, and long-term follow-up assessments.

Outcome Measures
Primary Outcomes (5)
Arm 1: Overall response rate
ORR is defined as percentage of participants with best overall confirmed response of complete response (CR) or partial response (PR) by the Response Assessment in Neuro-Oncology - high-grade glioma (RANO-HGG) criteria.
Up to 48 months
Arm 2: Number of participants reporting adverse events
An adverse event (AE) is any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention.
Up to 48 months
Arm 2: Number of participants with clinically significant changes in clinical chemistry parameters
Up to 48 months
Arm 2: Number of participants with clinically significant changes in hematology parameters
Up to 48 months
Arm 3: Overall response rate
Determined by the treating investigator and measured by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 or RANO-HGG criteria, as appropriate.
Up to 48 months
Secondary Outcomes (19)
Arm 1 and 3: Number of participants reporting adverse events
Up to 48 months
Arm 1 and 3: Number of participants with clinically significant changes in clinical chemistry parameters
Up to 48 months
Arm 1 and 3: Number of participants with clinically significant changes in hematology parameters
Up to 48 months
Arm 1: Area under the concentration-time curve (AUC) of Tovorafenib
Cycle 1: Day 1 and Day 15; Cycles 2, 4, 7, 10 and 13: Day 1
Arm 1: Minimum drug concentration (Cmin)
Cycle 1: Day 1 and Day 15; Cycles 2, 4, 7, 10 and 13: Day 1
- +14 more secondary outcomes
Study Arms (3)
Arm 1: Low-Grade Glioma
EXPERIMENTALParticipants with recurrent or progressive low-grade glioma will receive 420 milligrams/meters square (mg/m\^2) of tovorafenib weekly according to dose rounding guidelines and according to their baseline body surface area (BSA).
Arm 2: Low-Grade Glioma Expanded Access
EXPERIMENTALParticipants with recurrent or progressive low-grade glioma will receive 420 mg/m\^2 of tovorafenib weekly according to dose rounding guidelines and according to their baseline BSA.
Arm 3: Advanced Solid Tumor
EXPERIMENTALParticipants with advanced solid tumors will receive 420 mg/m\^2) of tovorafenib weekly according to dose rounding guidelines and according to their baseline BSA.
Interventions
Tovorafenib is an oral Type II RAF kinase inhibitor available in 100 mg immediate-release tablet or 25 mg/milliliter (mL) powder for reconstitution.
Eligibility Criteria
You may qualify if:
- Low Grade Glioma \& Low-Grade Glioma Extension: a relapsed or progressive LGG with documented known activating BRAF alteration.
- Advanced Solid Tumor: locally advanced or metastatic solid tumor with documented known or expected to be activating RAF fusion.
- Participants must have histopathologic verification of malignancy at either original diagnosis or relapse.
- Must have received at least one line of prior systemic therapy and have documented evidence of radiographic progression.
- Must have at least 1 measurable lesion as defined by RANO (Arms 1 \& 2) or RECIST v1.1 (Arm 3) criteria
You may not qualify if:
- Participant's tumor has additional previously-known activating molecular alterations.
- Participant has symptoms of without radiographically recurrent or radiographically progressive disease.
- Known or suspected diagnosis of neurofibromatosis type 1 (NF-1) via genetic testing or current diagnostic criteria.
