Firefly-1

Relapsed pLGG
(arms 1 and 2)

Advanced solid tumors harboring a known or expected to be activating RAF fusion (arm 3)

FIREFLY-1 is a pivotal Phase 2, multicenter open-label study designed to evaluate the safety and efficacy of tovorafenib in patients aged 6 months to 25 years with relapsed or progressive low-grade glioma or solid tumors harboring a known activating BRAF alteration. The low-grade glioma arms have completed enrollment. Results from the low-grade glioma registrational arm 1 ‘The type II RAF inhibitor tovorafenib in relapsed/refractory pediatric low-grade glioma: the phase 2 FIREFLY-1 trial’ were published in Nature Medicine in 2024.

Additional information about FIREFLY-1 may be found at ClinicalTrials.gov, using identifier NCT04775485.

FIREFLY-2

pLGG requiring front-line systemic drug therapy

FIREFLY-2 is a pivotal Phase 3, randomized, multicenter open-label trial to evaluate the efficacy, safety, and tolerability of tovorafenib monotherapy, an investigational, oral, RAF inhibitor versus standard of care (SoC) chemotherapy in patients with RAF-altered pediatric low-grade glioma requiring front-line systemic therapy. The primary endpoint will be overall response rate (ORR) based upon Response Assessment for Neuro-Oncology (RANO) criteria. Secondary endpoints include progression-free survival (PFS) by independent review committee (IRC) per RANO-LGG, duration of response (DOR) assessed by IRC per RANO-LGG, and overall survival.

Additional information about the FIREFLY-2 trial may be found at ClinicalTrials.gov, using identifier NCT05566795.

DAY301-001

Locally advanced or metastatic solid tumors

A Phase 1, Open Label, Multiple Dose, Dose Escalation and Expansion Study to Investigate the Safety, Tolerability, Pharmacokinetics and Anti-tumor Activity of the PTK7-Targeted Antibody-drug Conjugate DAY301 in Patients with Locally Advanced or Metastatic Solid Tumors.

Additional information about the DAY301-001 trial may be found at ClinicalTrials.gov, using identifier NCT06752681.
