DAY101 vs. Standard of Care Chemotherapy in Pediatric Participants With Low-Grade Glioma Requiring First-Line Systemic Therapy (LOGGIC/FIREFLY-2)
- Conditions
- Low-grade GliomaPediatric Low-grade GliomaRapidly Accelerated Fibrosarcoma (RAF) Altered Glioma
- Interventions
- Drug: Chemotherapeutic Agent
- Registration Number
- NCT05566795
- Lead Sponsor
- Day One Biopharmaceuticals, Inc.
- Brief Summary
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 participants with pediatric low-grade glioma (LGG) harboring an activating rapidly accelerated fibrosarcoma (RAF) alteration requiring first-line systemic therapy.
- Detailed Description
Approximately 400 treatment-naïve LGG participants 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. Participants will continue tovorafenib until any of the following occurs: disease progression, unacceptable toxicity, withdrawal of consent to treatment, or end of study.
Arm 2 (Investigator's Choice of SoC Chemotherapy): Participants will receive one of 4 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, vinblastine (VBL) regimen, or monthly carboplatin. The choice of SoC chemotherapy regimen will be selected prior to participant randomization. Treatment will continue until completion of therapy or until any of the following occurs: disease progression, unacceptable toxicity, withdrawal of consent to treatment, or end of study.
Participants who discontinue treatment due to disease progression will have (1) radiographic evidence of disease progression, as determined by the Investigator, or (2) clinical progression, as determined by the Investigator. Investigators are encouraged to discuss cases of clinical progression and early radiographic progression without clinical symptoms with the Sponsor Medical Monitor prior to treatment discontinuation or initiation of a different form of treatment for the malignancy. Participants may continue therapy beyond progressive disease (PD).

Group Intervention Description Tovorafenib Tovorafenib - Investigator's choice of Standard of care therapy Chemotherapeutic Agent -
- Primary Outcome Measures
Name Time Method Objective response rate (ORR) of tovorafenib monotherapy versus SoC chemotherapy Up to 60 months 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).
- Secondary Outcome Measures
Name Time Method Progression-free survival (PFS) of tovorafenib monotherapy versus SoC chemotherapy Up to 60 months PFS assessed per RAPNO criteria by IRC, and defined as time from randomization to PD or death from any cause, whichever comes first.
Change in best corrected visual acuity of tovorafenib monotherapy versus SoC chemotherapy in OPG participants aged ≥ 3 years Baseline and up to 5 years Visual acuity assessments to be performed by an ophthalmologist or another qualified site clinical personnel.
Visual progression-free survival (v-PFS) of tovorafenib monotherapy versus SoC chemotherapy Up to 60 months Visual progression-free survival is defined as the time from start of treatment to visual event for OPG participants aged ≥ 3 years.
PFS of tovorafenib monotherapy versus SoC chemotherapy Up to 60 months PFS per RANO-HGG or RANO-LGG criteria (as applicable), defined as time from randomization to PD or death from any cause, whichever occurs first.
Event-free survival (EFS) of tovorafenib monotherapy versus SoC chemotherapy Up to 60 months EFS assessed per RAPNO criteria by IRC, defined as time from randomization to PD, death from any cause, or initiation of any new anticancer therapy, whichever comes first.
Overall survival (OS) of tovorafenib monotherapy versus SoC chemotherapy Up to 60 months Overall survival is defined as time from randomization up to death from any cause.
Number of participants with any treatment-emergent adverse events, and Serious adverse events Up to 60 months Type, frequency, and severity of adverse events of tovorafenib monotherapy versus SoC chemotherapy will be assessed.
. Number of participants with clinically significant vital signs and laboratory abnormalities findings Up to 60 months Type, frequency, and severity of vital signs and laboratory abnormalities of tovorafenib monotherapy versus SoC chemotherapy will be assessed.
Change from baseline in Adaptive Behavior Composite Score (ABS) of tovorafenib monotherapy versus SoC chemotherapy Baseline, Year 1, 2 and 5 Adaptive behavior Composite Score will be evaluated using domain scores collected from the comprehensive Vineland III Adaptive Behavior Scale (VABS).
Change from baseline in the Motor Skills Domain Score of tovorafenib monotherapy versus SoC chemotherapy Baseline, Year 1, 2 and 5 The motor skills (gross and fine) will be assessed using the Motor Skills Score domain of the VABS in pediatric participants.
