PNOC026/DAY101-001: FIREFLY-1: A Phase 2, Open-Label, Multicenter Study to Evaluate the Safety and Efficacy of the Oral Pan-RAF Inhibitor DAY101 in Pediatric Patients with BRAF-Altered, Recurrent or Progressive Low-Grade Glioma

This is a Phase 2, multi-center, open label study of patient aged 6 months to 25 years with recurrent or progressive LGG with a known activating BRAF mutation. Patients will be treated with once weekly Day101 (an oral tablet or liquid suspension) for approximately 2 years, while undergoing routine clinic visits, labs, imaging, and other assessments.

Relapsed or progressive pediatric LGG is a serious, life-altering, and potentially fatal disease with significant disease-and treatment-associated morbidity. There is currently no standard of care for patients whose tumor progresses after initial therapy and no FDA-approved therapies. A majority of patients with pLGG have an alteration in BRAF; and using the Type II BRAF inhibitor DAY101 has been shown to penetrate the CNS and be well-tolerated in pediatric patients. This study aims to evaluate the efficacy and safety of DAY101 in pediatric patients with recurrent or progressive LGG with a known BRAF alteration.

To evaluate the overall response rate (ORR) as determined by an independent radiology review committee (IRC) and measured by the proportion of patients with best overall confirmed response of complete response (CR) or partial response (PR) by Response Assessment in Neuro-Oncology (RANO) criteria following treatment with DAY101 in pediatric patients aged 6 months to 25 years of age with a relapsed or progressive low-grade glioma (LGG) harboring a known activating BRAF alteration.

Inclusion Criteria:

  • Age 6 months to 25 years with a relapsed or progressive LGG with known activating BRAF alteration
  • Confirmation of histopathologic diagnosis of LGG and molecular diagnosis of activating BRAF alteration
  • Must have received at least one line of systemic therapy and have evidence of radiographic progression
  • Must have at least 1 measurable lesion as defined by RANO criteria

Exclusion Criteria:

  • Patient’s tumor has additional previously-known activating molecular alterations
  • Patient has symptoms of clinical progression in the absence of radiographic progression
  • Known or suspected diagnosis of neurofibromatosis type 1 (NF-1)
  • Other inclusion/exclusion criteria as stipulated by protocol may apply
