Welcome back to the D.I.S.C.O., FDA’s Drug Information Soundcast in Clinical Oncology, Burst Edition, brought to you by FDA’s Division of Drug Information in partnership with FDA’s Oncology Center of Excellence. Today we’ll provide a quick update on a recent FDA cancer drug approval.
On September 30, 2022, the FDA granted accelerated approval to futibatinib, brand name Lytgobi for adult patients with previously treated, unresectable, locally advanced or metastatic intrahepatic cholangiocarcinoma harboring fibroblast growth factor receptor 2 gene fusions or other rearrangements.
Efficacy was evaluated in TAS-120-101, a multicenter, open-label, single-arm trial that enrolled 103 patients with previously treated, unresectable, locally advanced, or metastatic intrahepatic cholangiocarcinoma harboring a fibroblast growth factor receptor 2 gene fusion or other rearrangement. The presence of fibroblast growth factor receptor 2 fusions or other rearrangements was determined using next generation sequencing testing.
The major efficacy outcome measures were overall response rate and duration of response as determined by an independent review committee according to RECIST v1.1. Overall response rate was 42%; all 43 responders achieved partial responses. The median duration of response was 9.7 months.
The most common adverse reactions occurring in 20% or more of patients were nail toxicity, musculoskeletal pain, constipation, diarrhea, fatigue, dry mouth, alopecia, stomatitis, abdominal pain, dry skin, arthralgia, dysgeusia, dry eye, nausea, decreased appetite, urinary tract infection, palmar-plantar erythrodysesthesia syndrome, and vomiting.
This review used the Real-Time Oncology Review pilot program, which streamlined data submission prior to the filing of the entire clinical application, and the Assessment Aid, a voluntary submission from the applicant to facilitate the FDA’s assessment.
Full prescribing information for these approvals can be found on the web at www.fda.gov/drugsatFDA.
Health care professionals should report serious adverse events to FDA’s MedWatch Reporting Program at www.fda.gov/medwatch.
