ORR assessed per Response Assessment in Pediatric Neuro Oncology (RAPNO) criteria by Independent Review Committee (IRC), and defined as the proportion of participants with overall confirmed response of complete response (CR), partial response (PR), or minor response (MR).
Progression-free survival is defined as the time of documented response until disease progression as defined by Response assessment in neuro-oncology criteria (RANO) criteria. PFS will be reported by overall group at 12 months.
Scores over time from the PedsQL 4.0 Generic Core physical function domain rating form, which have multidimensional child self-report and parent proxy report scales to assess health-related quality of life (QOL) in children, adolescents, and young adults ages 2 - 25 years will be reported. Physical functioning, is the sub-scale of interest for this protocol. Items on the physical functioning sub-scale are scored on a 5-point Likert scale with raw scores ranging from 0- 4. Items are reversed scored and linearly transformed to a 0-100 scale. If more than 50% of the items in the scale are missing, the Scale Scores should not be computed. Higher scores indicate a higher level of physical functioning
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.
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.
Determined by the treating investigator and measured by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 or RANO-HGG criteria, as appropriate.

| Group 1: Neoadjuvant Tovorafenib | EXPERIMENTAL | Participants with newly diagnosed craniopharyngioma will receive one (1) dose of Tovorafenib within 7 days +/- 2 days prior to planned biopsy or resection. At completion of biopsy or resection, participants having undergone biopsy only or sub-total (STR) or near-total resection (NTR) will continue on maintenance monotherapy of Tovorafenib given once weekly at the respected recommended phase 2 dose (RP2D). Participants having undergone a gross total resection (GTR) will enter into follow-up only and will be part of the exploratory cohort. |
| Group 2, Arm A: Neoadjuvant Tovorafenib | EXPERIMENTAL | Participants with recurrent craniopharyngioma will receive one (1) dose of Tovorafenib within 7 days +/- 2 days prior to planned biopsy or resection. At completion of biopsy or resection, participants having undergone biopsy only or STR or NTR will continue on maintenance monotherapy of Tovorafenib given once weekly at the respected RP2D. |
| Group 2, Arm B: Non-biopsy/resection participants | EXPERIMENTAL | Non-biopsy/resection participants with recurrent disease will receive monotherapy of Tovorafenib given once weekly at the respected RP2D. |
| Arm 1: Low-Grade Glioma | EXPERIMENTAL | Participants 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 | EXPERIMENTAL | Participants 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 | EXPERIMENTAL | Participants with advanced solid tumors will receive 420 mg/m\^2) of tovorafenib weekly according to dose rounding guidelines and according to their baseline BSA. |

Tovorafenib is an investigational small molecule being studied for the treatment of pediatric low-grade glioma and craniopharyngioma in children and young adults. It is also being evaluated in advanced solid tumors. The drug is in clinical development and has not been approved by the FDA.
Tovorafenib is a RAF inhibitor that targets RAF1, BRAF, and ARAF kinases. By inhibiting these proteins, it is designed to interfere with signaling pathways involved in tumor growth. This mechanism is being investigated in pediatric low-grade glioma and craniopharyngioma.
Tovorafenib is being developed by Day One Biopharmaceuticals, Inc., a company traded on NASDAQ under the ticker DAWN. The company is conducting clinical trials of the drug in pediatric and young adult patients with certain brain tumors.
Tovorafenib is in Phase 2 clinical trials for pediatric low-grade glioma and craniopharyngioma, and a Phase 3 trial is also listed for low-grade glioma. It is an investigational drug with FDA designations including Priority Review, Breakthrough Therapy, Orphan Drug, and Rare Pediatric Disease.
Tovorafenib is being studied in NCT04775485, a Phase 2 trial in pediatric and young adult patients with relapsed or progressive low-grade glioma and advanced solid tumors. It is also in NCT05465174, a Phase 2 trial for craniopharyngioma, and NCT05566795, a Phase 3 trial comparing it to chemotherapy in pediatric low-grade glioma.
Yes, Tovorafenib is also known as DAY101. The Phase 3 trial NCT05566795 is titled 'DAY101 vs. Standard of Care Chemotherapy in Pediatric Participants With Low-Grade Glioma Requiring First-Line Systemic Therapy (LOGGIC/FIREFLY-2)', confirming that DAY101 is an alternative name for the same drug.
