Detailed Description

Study TAS-120-301 is an open-label, multinational, parallel 2-arm, randomized Phase 3 study evaluating the efficacy and safety of futibatinib versus gemcitabine-cisplatin chemotherapy as first-line treatment of patients with advanced, metastatic, or recurrent unresectable iCCA harboring FGFR2 gene rearrangements. Eligible patients will be randomized on a 1:1 basis to the following study arms:

- Experimental Arm: Patients will receive futibatinib at an oral dose of 20 mg, administered daily (QD) on every day of a 21-day cycle.

- Control Arm: On Days 1 and 8 of a 21-day cycle, patients will receive:

- Cisplatin 25 mg/m2 in 1000 mL 0.9% saline by intravenous (I.V.) infusion over 1 hour, followed by 500 mL 0.9% saline over 30 minutes; and

- Gemcitabine 1000 mg/m2 in 250-500 mL 0.9% saline by I.V. infusion over 30 minutes, beginning after completion of the cisplatin and saline infusions.

Patients in the Experimental Arm may continue to receive continuous futibatinib until documentation of progressive disease (PD) per RECIST 1.1, or until other withdrawal criteria are met, whichever comes first. However, treatment may continue following PD per RECIST 1.1 if the patient is clinically stable and is considered by the Investigator to be deriving continued clinical benefit from futibatinib.

Patients in the Control Arm may receive gemcitabine-cisplatin chemotherapy for up to 8 cycles or until PD or other withdrawal criteria are met, whichever comes first. Patients who discontinue gemcitabine-cisplatin due to documented disease progression (by ICR) may receive treatment with futibatinib ("crossover"), if medically appropriate in the opinion of the Investigator and if criteria for futibatinib treatment are met.

    • Cisplatin/Gemcitabine is currently 1st line standard of care

Arms, Groups and Cohorts

  • Experimental: TAS-120
    • TAS-120 tablets, oral; 28-day cycle
  • Active Comparator: Cisplatin/Gemcitabine
    • • On Days 1 and 8 of a 21-day cycle, patients will receive: Cisplatin 25 mg/m2 in 1000 mL 0.9% saline by intravenous (I.V.) infusion over 1 hour, followed by 500 mL 0.9% saline over 30 minutes; and Gemcitabine 1000 mg/m2 in 250-500 mL 0.9% saline by I.V. infusion over 30 minutes, beginning after completion of the cisplatin and saline infusions.

Clinical Trial Outcome Measures

Primary Measures

  • Measurements of disease will be performed using RECIST guidelines. Tumor assessments CT or MRI will be performed at baseline and at the end of every 2 cycles up to Cycle 4 and every 3 cycles beyond cycle 4 (or as clinically indicated).
    • Time Frame: 10 months
    • Response assessments will be made based on RECIST guidelines (version 1.1, 2009) for solid tumors

Secondary Measures

  • ORR
    • Time Frame: 10 months
    • defined as the proportion of patients experiencing a best overall response of partial response (PR) or complete response (CR) (per RECIST 1.1), based on ICR.
  • DCR
    • Time Frame: 10 months
    • defined as the proportion of patients experiencing a best overall response of partial response (PR) or complete response (CR) (per RECIST 1.1), based on ICR.
  • PFS per Investigator assessment
    • Time Frame: 10 months
    • defined as the time from date of randomization to the date of disease progression based on Investigator assessment of radiographic images or death, whichever occurs first.
  • DOR
    • Time Frame: 10 months
    • defined as the time from the first documentation of response (per RECIST 1.1 and based on central assessment of radiologic images) to the first documentation of objective tumor progression or death due to any cause, whichever occurs first.
  • PFS2
    • Time Frame: 10 months
    • defined as the time from randomization to subsequent disease progression per Investigator assessment after initiation of next-line therapy or death from any cause (whichever occurs first).
