Abstract 2550

Background

Fibroblast growth factor receptor (FGFR) 2 alterations are implicated in CCA. Pemigatinib is a selective, potent, oral FGFR1, 2, and 3 inhibitor. We present data from a phase II, open label, single arm study of pemigatinib in pts with previously treated locally advanced or metastatic CCA (NCT02924376).

Methods

Eligible adults had disease progression after ≥1 prior treatment and documented FGF/FGFR gene status. Pts assigned to cohorts A (FGFR2 gene rearrangements/fusions), B (other FGF/FGFR gene alterations), or C (no FGF/FGFR gene alterations) received oral pemigatinib 13.5 mg QD (21-day cycle; 2 weeks on, 1 week off) until disease progression/unacceptable toxicity. Primary endpoint was centrally confirmed objective response rate (ORR; cohort A); secondary endpoints were ORR (cohorts B, A+B, and C); duration of response (DOR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and safety.

Results

At data cutoff (Mar 22, 2019), 146 pts were enrolled (cohort A, n = 107; B, n = 20; C, n = 18; 1 pt undetermined). Median (range) age was 59 (26–78) years; 61% and 39% had 1 and ≥2 prior therapies, respectively. Fewer pts discontinued therapy in cohort A (71%) vs B and C (each 100%), mainly for progressive disease (53%, 75%, and 67%, respectively). ORR in cohort A was 35.5% (95% CI, 26.5%–45.4%), with 3 complete responses; median (m) DOR was 7.5 (95% CI, 5.7–14.5) months (mo), DCR was 82% (95% CI, 74%–89%), mPFS and mOS were 6.9 (95% CI, 6.2–9.6) and 21.1 (14.8–not reached) mo (OS not mature at cutoff). In cohorts B and C, no patient achieved a response. Overall, most common adverse events (AEs) were hyperphosphatemia (60%; grade ≥3, 0%), alopecia (49%; 0%), diarrhea (47%; 3%), fatigue (42%; 5%), nail toxicities (42%; 2%), and dysgeusia (40%; 0%). Hyperphosphatemia was managed with diet modifications, phosphate binders, if needed; diuretics or dose reductions/interruptions. Discontinuation, dose reduction and interruption due to AEs occurred in 9%, 14% and 42% of patients, respectively.

Conclusions

These data support pemigatinib as a potential treatment option for previously treated pts with CCA harboring FGFR2 gene rearrangements/fusions.
