|Title||FIGHT-101, a first-in-human study of potent and selective FGFR 1-3 inhibitor pemigatinib in pan-cancer patients with FGF/FGFR alterations and advanced malignancies.|
|Abstract Text||The phase I/II FIGHT-101 study (NCT02393248) evaluated safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of pemigatinib, a potent and selective fibroblast growth factor receptor (FGFR) 1-3 inhibitor, as monotherapy or in combination therapy, for refractory advanced malignancies, with and without fibroblast growth factor (FGF) and receptor (FGFR) gene alterations.Eligible, molecularly unselected patients with advanced malignancies were included in part 1 (dose escalation; 3 + 3 design) to determine the maximum tolerated dose. Part 2 (dose expansion) evaluated the recommended phase II dose in tumors with or where FGF/FGFR activity is relevant.Patients (N = 128) received pemigatinib 1-20 mg once daily intermittently (2 weeks on/1 week off; n = 70) or continuously (n = 58). No dose-limiting toxicities were reported. Doses ≥4 mg were pharmacologically active (maximum tolerated dose not reached; recommended phase II dose 13.5 mg once daily). The most common treatment-emergent adverse event (TEAE) was hyperphosphatemia (75.0%; grade ≥3, 2.3%); the most common grade ≥3 TEAE was fatigue (10.2%). Dose interruption, dose reduction, and TEAE-related treatment discontinuation occurred in 66 (51.6%), 14 (10.9%), and 13 (10.2%) patients, respectively. Overall, 12 partial responses were achieved, most commonly in cholangiocarcinoma (n = 5) as well as in a broad spectrum of tumors including head and neck, pancreatic, gallbladder, uterine, urothelial carcinoma, recurrent pilocytic astrocytoma, and non-small-cell lung cancer (each n = 1); median duration of response was 7.3 months [95% confidence interval (CI) 3.3-14.5 months]. Overall response rate was highest for patients with FGFR fusions/rearrangements [n = 5; 25.0% (95% CI 8.7% to 49.1%)], followed by those with FGFR mutations [n = 3; 23.1% (95% CI 5.0% to 53.8%)].Pemigatinib was associated with a manageable safety profile and pharmacodynamic and clinical activity, with responses seen across tumors and driven by FGFR fusions/rearrangements and mutations. These results prompted a registrational study in cholangiocarcinoma and phase II/III trials in multiple tumor types demonstrating the benefit of precision therapy, even in early phase trials.|
