Study of AG-120 in Previously Treated Advanced Cholangiocarcinoma With IDH1 Mutations (ClarIDHy)

Study Summary

Study AG120-C-005 is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study of orally administered AG-120. Participants, all personnel involved in the evaluation of participants' response to treatment (e.g., Investigators, study coordinators, study pharmacists), and designated Sponsor team members will be blinded to study treatment. Participants are required to have a histologically-confirmed diagnosis of isocitrate dehydrogenase-1 (IDH1) gene-mutated cholangiocarcinoma that is not eligible for curative resection, transplantation, or ablative therapies prior to enrollment. IDH1 mutation testing will be performed at participating investigative sites. Participants must have progression of disease and have received at least 1 but not more than 2 prior treatment regimens for advanced disease (nonresectable or metastatic). All participants must have received either a gemcitabine or a 5 fluorouracil (5-FU) based chemotherapy regimen.

Primary Outcome

PFS is defined as the time from date of randomization to the date of first documented disease progression as assessed by the IRC using Response Evaluation Criteria in Solid Tumors \[RECIST\] v1.1, or date of death due to any cause, whichever occurred first. Disease progression was defined as greater than or equal to (≥)20 percent (%) increase in sum of the diameter of target lesions, taking as reference the smallest sum diameter recorded since the treatment started. In addition to the relative i
