Brief description of study

What is the purpose of this study?
This is a 2-arm, randomized, open-label, multicenter, global, Phase 3 trial to evaluate the efficacy, safety, and tolerability of tovorafenib monotherapy versus standard of care (SoC) chemotherapy in patients with pediatric low-grade glioma (LGG) harboring an activating rapidly accelerated fibrosarcoma (RAF) alteration requiring front-line systemic therapy.

THIS STUDY IS ENROLLING BY INVITATION ONLY - Consistent with most oncology trials, patients are not actively “recruited,” but are screened by their physician for appropriate clinical trial(s) at the time of their routine clinic visit. Occasionally, a patient may be a self-referral or physician referral, but are still screened for appropriate clinical trials at the time of their routine clinic visit. PI and staff may send copies of relevant consent forms to these patients to look over prior to actually consenting or enrolling them. This may take place at the patient's visit at which the consent is presented or the patient's next visit to the outpatient hematology/oncology clinic.

Detailed description of study

What will happen during the study?
  • Approximately 400 treatment-naïve low-grade glioma patients will be randomized 1:1 to either tovorafenib (Arm 1) or an Investigator's choice of SoC chemotherapy (Arm 2).
  • Arm 1 (tovorafenib): treatment cycles will repeat every 28 days in the absence of disease progression. Patients will continue tovorafenib until any of the following occurs: disease progression based on Response Assessment in Neuro-Oncology (RANO-LGG) criteria, unacceptable toxicity, withdrawal of consent to treatment, or end of study.
  • Arm 2 (Investigator's Choice of SoC Chemotherapy): patients will receive one of 3 SoC chemotherapy options selected by the treating Investigator: Children's Oncology Group - Vincristine/Carboplatin (COG-V/C) regimen, International Society for Paediatric Oncology - Low-Grade Glioma Vincristine/Carboplatin (SIOPe-LGG-V/C) regimen, or vinblastine (VBL) regimen. The choice of SoC chemotherapy regimen will be selected prior to patient randomization. Treatment will continue until completion of therapy or until any of the following occurs: disease progression based on RANO-LGG criteria, unacceptable toxicity, withdrawal of consent to treatment, or end of study.
  • Patients who discontinue treatment due to disease progression will have (1) radiographic evidence of progressive disease based on RANO-LGG, as determined by the Investigator and confirmed by the IRC, or (2) clinical progression based on RANO-LGG criteria determined by the Investigator. Investigators are encouraged to discuss cases of clinical progression and early radiographic progression without clinical symptom with the Sponsor Medical Monitor prior to treatment discontinuation or initiation of a different form of treatment for the malignancy. 
  • Patients may continue therapy beyond progressive disease
