A Study to Assess the Efficacy and Safety of FORE8394 in Participants With Cancer Harboring BRAF Alterations
What this study is about
The objective of this Master Protocol is to evaluate the effectiveness and safety of plixorafenib in participants with locally advanced or metastatic solid tumors, or recurrent or progressive primary central nervous system (CNS) tumors harboring BRAF fusions, or in participants with rare BRAF V600-mutated solid tumors, melanoma, thyroid, or recurrent primary CNS tumors.

Inclusion criteria
- Subprotocol A: 1. Male and female, ≥10 years of age, and weighing ≥30 kg. 2. Histologic diagnosis of a solid tumor or primary CNS tumor. 3. Documentation of BRAF gene fusion in tumor and/or blood detected by an analytically validated test by DNA sequencing or RNA (transcriptome) sequencing. 4. Have an archival tissue sample available meeting protocol requirements. 5. Consent to provide scan(s) prior to baseline to assess change in tumor trajectory. 6. Received all available standard therapy, is intolerant to available therapies, or the investigator has determined that treatment with standard therapy is not appropriate. 7. All adverse events related to prior therapies (chemotherapy; radiotherapy; surgery) must have resolved to Grade 1 or baseline. Subprotocol B: 1. Male and female, ≥10 years of age, and weighing ≥30 kg. 2. Histological diagnosis of a primary CNS tumor, including but not limited to the following: 1. Adults (≥18 years) with Grade 1-4 glioma or g

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
