51P - Pooled analysis safety profile of futibatinib in patients with advanced solid tumors, including intrahepatic cholangiocarcinoma (iCCA)
- Funda Meric-Bernstam (Houston, TX, United States of America)
Futibatinib, an irreversible FGFR1–4 inhibitor, has shown efficacy in iCCA with
Pts who received ≥1 futibatinib dose at 20 mg QD in a global phase I/II (NCT02052778) and a Japanese phase I study (JapicCTI-142552) were included in this retrospective analysis. AEs, treatment (tx)-related AEs (TRAEs), AEs of special interest (AESIs), and time to onset/resolution (TTO/TTR) of AESIs were analyzed.
As of October 1, 2020, 318 pts had received futibatinib 20 mg QD across trials (median [m] duration, 111 d). The most common tumor types were CCA (60%), primary CNS tumors (11%), and gastric cancer (9%); 98% had received ≥1 prior tx. Overall, 43% of pts experienced grade (gr) 3 TRAEs, and 1% gr 4 TRAEs; no gr 5 TRAEs were reported. The most frequent gr ≥3 TRAE was hyperphosphatemia (in 23%; defined as ≥7 mg/dL serum phosphate), followed by increased alanine aminotransferase (6%) and increased aspartate aminotransferase (5%). Gr ≥3 diarrhea (<1%), nausea (1%), stomatitis (3%), and fatigue (3%) were rare. Nearly all cases of gr 3 hyperphosphatemia resolved (73/75; mTTR, 7 d) with phosphate binders and dose adjustments. Other AESIs were mostly mild to moderate in severity (nail toxicities [gr ≥3: 1%], hepatotoxicity [gr ≥3: 12%], and palmar-plantar erythrodysesthesia [gr ≥3: 3%]); most gr ≥3 events resolved. Retinal toxicities occurred in 8% of pts (all gr 1–2), and 2% had a TRAE of cataract (gr ≥3: 1%). Management of TRAEs included dose adjustments (54% of pts). Overall, 3% of pts discontinued tx due to TRAEs (only diarrhea and stomatitis in >1 pt [n=2 each]; none due to hyperphosphatemia). No obvious differences in safety were noted between tumor types.
Futibatinib was safe and tolerable in this pooled analysis of pts with advanced solid tumors. In the majority of pts, TRAEs were gr 1–2 in severity, and most gr ≥3 events resolved with adequate management. Tx-related discontinuations were rare.
