Trial Outcomes & Findings for Gemcitabine and Cisplatin With Ivosidenib or Pemigatinib for the Treatment of Unresectable or Metastatic Cholangiocarcinoma (NCT NCT04088188)

NCT ID: NCT04088188

Last Updated: 2024-05-06

Results Overview

A significant toxicity is defined as a Dose Limiting Toxicity that is possibly, probably, or definitely related to treatment. DLTs will be evaluated starting in the first cycle of combination treatment and up to 3 weeks of combination treatment. Toxicities will be assessed using the CTEP Active Version of the CTCAE. All patients meeting the eligibility criteria who have signed a consent form and have begun combination treatment will be considered evaluable for significant toxicity. Patients, who do not experience a DLT but withdraw from protocol therapy prior to 3 weeks, will not be evaluable for the primary endpoint. Incidence of significant toxicity at 3 weeks will be estimated separately by arm and will be defined as the number of patients with significant toxicity within 3 weeks of combination treatment divided by the total number of evaluable patients.

PRIMARY outcome

Timeframe: 3 weeks

Population: Only patients that completed cycle 1 treatment per protocol were evaluated.

A significant toxicity is defined as a Dose Limiting Toxicity that is possibly, probably, or definitely related to treatment. DLTs will be evaluated starting in the first cycle of combination treatment and up to 3 weeks of combination treatment. Toxicities will be assessed using the CTEP Active Version of the CTCAE. All patients meeting the eligibility criteria who have signed a consent form and have begun combination treatment will be considered evaluable for significant toxicity. Patients, who do not experience a DLT but withdraw from protocol therapy prior to 3 weeks, will not be evaluable for the primary endpoint. Incidence of significant toxicity at 3 weeks will be estimated separately by arm and will be defined as the number of patients with significant toxicity within 3 weeks of combination treatment divided by the total number of evaluable patients.

SECONDARY outcome

Timeframe: 27 months

Overall survival is defined to be the length of time from start of study therapy to death due to any cause. All patients meeting the eligibility criteria that have signed a consent form and begun treatment will be considered evaluable for estimation of the survival distribution. The distribution of overall survival for both arms of the study will be estimated separately using the Kaplan-Meier method.

SECONDARY outcome

Timeframe: 24 months

Progression free survival time is defined as the time from the start of study therapy to documentation of disease progression. Patients who die without documentation of progression will be considered to have had tumor progression at the time of death. Patients who are still alive and have not progressed will be censored for progression at the time of the last disease evaluation. The time-to-progression distribution will be estimated separately for both arms, using the Kaplan-Meier method.

SECONDARY outcome

Timeframe: 16 months

The term toxicity is defined as adverse events that are classified as either possibly, probably, or definitely related to study treatment. Non-hematologic toxicities will be evaluated via the ordinal Common Terminology Criteria (CTC) standard toxicity grading. Hematologic toxicity measures of thrombocytopenia, neutropenia, and leukopenia will be assessed using continuous variables as the outcome measures (primarily nadir) as well as categorization via CTC standard toxicity grading. Overall toxicity incidence as well as toxicity profiles by dose level, patient and tumor site will be explored and summarized. Frequency distributions, graphical techniques and other descriptive measures will form the basis of these analyses.

Timeframe: 15 months

Best Response is defined to be the best objective status recorded from the start of the treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the treatment started). The patient's best response assignment will depend on the achievement of both measurement and confirmation criteria. Response Evaluation Criteria in Solid Tumors 1.1 criteria will be used for tumor evaluation and patients will be re-evaluated every prior to treatment in cycle 3 and then in odd subsequent cycles. Responses will be summarized by simple descriptive summary statistics delineating complete and partial responses as well as stable and progressive disease in this patient population (overall and by tumor group).
