Brief summary
The purpose of this study is to evaluate the efficacy and safety of pemigatinib in participants with previously treated locally advanced/metastatic or surgically unresectable solid tumors harboring activating FGFR mutations or translocations.
Interventions
Pemigatinib administered orally once daily.

Study design
Intervention model description
Participants will be assigned to 1 of 2 cohorts (Cohort A: FGFR1-3 in-frame fusions or FGFR2 intron 17 rearrangements; Cohort B: Known/predicted activating point mutations in FGFR1-3 \[excluding kinase domain\]) but there is no difference in the treatment regimen between the cohorts.
Eligibility
Inclusion criteria
* Histologically or cytologically confirmed solid tumor malignancy that is advanced or metastatic (Stage IIIB or IV) or is surgically unresectable. * Radiographically measurable disease (per RECIST v1.1 or RANO for primary brain tumors). * Documentation of an FGFR1-3 gene mutation or translocation. * Objective disease progression after at least 1 prior therapy. * Not eligible or able to participate in any other Incyte-sponsored clinical trial.
Exclusion criteria
* Advanced/metastatic bladder cancer or advanced/metastatic cholangiocarcinoma. * Prior receipt of a selective FGFR inhibitor. * Current evidence of clinically significant corneal or retinal disorder. * History of calcium and phosphate hemostasis disorder or systemic mineral imbalance with ectopic calcification of soft tissues.

Participant flow
Recruitment details
Approximately 50 participants were planned for enrollment. However, only 1 participant was enrolled in the study (assigned to Cohort A) and data was analyzed for safety. The study was closed for lack of enrollment in 2021.
Pre-assignment details
A total of 1 participant (assigned to Cohort A) was enrolled in the study, received at least 1 dose of pemigatinib, and was included in the safety population. The participant withdrew consent after Cycle 2+. As a result, there was no efficacy evaluable population.

Outcome results
Objective Response Rate (ORR)
Defined as the proportion of participants in each cohort who achieve a complete response (CR) or partial response (PR) based on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1)
Time frame: Up to approximately 6 months
Population: Due to low participant enrollment (n=1), efficacy analyses were not conducted.

Time frame: Up to approximately 6 months
Population: Due to low participant enrollment (n=1), efficacy analyses were not conducted.
Duration of Response (DOR)
Defined as the time from the date of first assessment of CR or PR until the date of the first progressive disease (per RECIST v1.1 or RANO) or death (whichever is first) in each cohort.
Time frame: Up to approximately 6 months
Population: Due to low participant enrollment (n=1), efficacy analyses were not conducted.
