Trial Outcomes & Findings for Safety and Efficacy of Pemigatinib in Patients With High-risk Urothelial Cancer After Radical Surgery (NCT NCT04294277)

NCT ID: NCT04294277

Last Updated: 2025-04-18

Results Overview

In the protocol, RFS at Year 2 was defined as the time from the start of treatment until disease relapse by Investigator determination, study-end or lost to follow-up, or death due to any cause. Due to the Covid-19 crisis causing significant delay of recruitment and the fact that we needed much more patients to identify patients with FGFR3 alterations, the study recruitment was prematurely stopped in November 2021 when 46 patients were screened and only 4 among 42 tested (9.5%) patients were identified with FGFR3 alterations. Two of the FGFR3 positive patients started treatment and the others were ineligible for the study. Since patients withdrawing from the study before completing the study period of 2 years cannot be included in the calculation of the 2-year RFS rate, the outcome results through premature study-end are presented.

Measure
Treatment Arm
Treatment with Pemigatinib at the protocol-defined dose administered orally once daily as continuous therapy schedule until 12 months. Pemigatinib: At Day 1, prior to the start of treatment, results from screening visit evaluations are reviewed to determine eligibility requirements. Subsequent visits during treatment phase will take place at Day 8, Day 15 and Day 21 and subsequently at 3 week intervals. Timing of subsequent visits can be prolonged to max. 9 week intervals if no problems exist during the first 12 weeks of therapy. Subjects will self-administer study drug using an oral QD regimen in a continuous dosing schedule. Each dose of Pemigatinib should be taken first thing in the morning upon waking or after a 2-hour fast; subjects should then fast for an additional 1 hour after taking study drug. The starting dose is 13.5 mg Pemigatinib. Study treatment will continue until 12 months, or until the evidence of disease relapse or onset of unacceptable toxicity.

PRIMARY outcome

Timeframe: Mean Relapse-free survival rate from start of treatment through premature study-end with a maximal follow-up of 62 weeks.

Population: 2 patients started treatment with Pemigatinib and were followed-up according to protocol through premature study-end.

In the protocol, RFS at Year 2 was defined as the time from the start of treatment until disease relapse by Investigator determination, study-end or lost to follow-up, or death due to any cause. Due to the Covid-19 crisis causing significant delay of recruitment and the fact that we needed much more patients to identify patients with FGFR3 alterations, the study recruitment was prematurely stopped in November 2021 when 46 patients were screened and only 4 among 42 tested (9.5%) patients were identified with FGFR3 alterations. Two of the FGFR3 positive patients started treatment and the others were ineligible for the study.

Mean Overall Survival of patients who started treatment with Pemigatinib is defined as the time from the start of treatment until the last date known alive, or death due to any cause through premature study-end.
