GAVRETO™ demonstrated durable response with or without prior therapy1

ARROW study design in the NSCLC population

Efficacy and safety with GAVRETO (400 mg orally once daily) was evaluated in patients with RET fusion+ mNSCLC in the ARROW study, a phase 1/2, nonrandomized, open-label, single-arm, multicohort, multicenter clinical trial. Patients with asymptomatic central nervous system metastases, including patients with stable or decreasing steroid use within 2 weeks prior to study entry, were enrolled.

Efficacy results with GAVRETO

The major efficacy outcome measures were overall response rate (ORR) and duration of response (DoR), as assessed by a blinded independent central review (BICR) according to RECIST v1.1.
