The efficacy of PEMAZYRE® (pemigatinib) was investigated in the FIGHT–202 clinical study (N=108)1

Histogram and magnifying glass

FIGHT–202 was a multicentre, open-label, single-arm study to evaluate the efficacy and safety of PEMAZYRE in previously treated patients with locally advanced/metastatic or surgically unresectable cholangiocarcinoma (CCA).1

The efficacy population consisted of 108 patients (105 patients with intrahepatic disease) whose disease had progressed after at least 1 prior therapy and who had fibroblast growth factor receptor 2 (FGFR2) fusion or rearrangement, as determined by the test performed at a central laboratory.1

Patients received PEMAZYRE in 21-day cycles consisting of 13.5 mg once-daily oral dosing for 14 days, followed by 7 days off therapy. PEMAZYRE was administered until disease progression or unacceptable toxicity.1

The major efficacy outcome measures were objective response rate (ORR) and duration of response (DOR), as determined by an independent review committee according to RECIST v1.1.1

Histogram showing best percentage change from baseline in target lesion size

Tumour response was assessed by independent review. Coloured bars indicate confirmed responses assessed by Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1. Dotted lines indicate the cutoff for partial response (defined as at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum diameters) and progressive disease (defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study).2,3
*Patient had a decrease in target lesion size but was not evaluable for response using RECIST.2
