Introduction to Pemigatinib
Pemigatinib, marketed as Pemazyre, is a selective, potent, oral inhibitor of fibroblast growth factor receptors (FGFR) 1, 2, and 3. It has been pivotal in the treatment of advanced cholangiocarcinoma, particularly in patients with FGFR2 gene alterations.
Clinical Trials Update
FIGHT-202 Study
The most significant clinical trial for pemigatinib is the FIGHT-202 study, a multicenter, open-label, single-arm, phase II trial. This study enrolled 147 patients with previously treated, advanced or metastatic cholangiocarcinoma, focusing on those with FGFR2 fusions or rearrangements. Patients received pemigatinib at a dose of 13.5 mg once daily in 21-day cycles (2 weeks on, 1 week off) until disease progression or unacceptable toxicity.
- Key Outcomes: The objective response rate (ORR) in the primary cohort was 37.0%, with complete and partial responses observed in 3 and 37 patients, respectively. The median duration of response (DOR) was 9.1 months, while the median progression-free survival (PFS) and overall survival (OS) were 7.0 months and 17.5 months, respectively[1].
Safety Profile
The most common treatment-emergent adverse events (TEAEs) included hyperphosphatemia (58.5%), alopecia (49.7%), and diarrhea (47.6%). Despite these side effects, pemigatinib demonstrated a manageable safety profile, with only 10.2% of patients discontinuing treatment due to TEAEs[1].
Other Clinical Studies
In addition to FIGHT-202, pemigatinib has been evaluated in other clinical studies, including two phase I open-label, multicenter, dose escalation and expansion studies (INCB 54828-101 and INCB 54828-102). These studies assessed the safety, tolerability, and pharmacological activity of pemigatinib in subjects with advanced malignancies[3][4].
