District of Columbia
I. To assess overall response rate (ORR) of pemigatinib in patients with metastatic or unresectable colorectal cancer harboring activating FGFR alterations.
I. To assess the clinical benefit rate (complete response + partial response + stable disease) with pemigatinib.
II. To assess progression free survival (PFS) and overall survival (OS) with pemigatinib.
III. Assess changes in patient quality of life (QOL) as measured by the linear analogue self-assessment (LASA) questionnaire.
IV. Assess the frequency and severity of adverse events.
CORRELATIVE RESEARCH OBJECTIVES:
I. To assess plasma pharmacodynamic biomarkers of response and resistance to therapy.
II. To explore any correlation between tissue and blood based biomarkers and clinical outcomes.
Patients receive pemigatinib orally (PO) once daily (QD) on days 1-21. Treatment repeats every 21 days for up to 35 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 3 years after registration.
