Study Details
Study Description
Brief Summary
A Phase 3b research study to collect additional data that ivosidenib is safe and effective in adult patients with advanced or metastatic bile duct cancer, cholangiocarcinoma (CCA). All patients who meet enrollment criteria will be enrolled to receive ivosidenib tablets orally once daily for 28 day cycles, continuing as long as clinical benefit and consent for participation is maintained. There will be a minimum of 6 study visits from screening until the final follow-up, if one cycle of treatment is completed and consent is maintained through 18 months of follow-up. Each additional cycle completed will add one study visit, on the first day of each cycle.

Detailed Description
Ivosidenib is approved in the United States for the treatment of advanced or metastatic CCA; this study is being conducted to collect additional data related to the safety, efficacy, and impact on quality of life for patients. This is an open-label, single-arm study of ivosidenib, which means that all patients meeting eligibility criteria will receive two 250 mg ivosidenib tablets, totaling 500mg of drug, to be taken orally, once daily, for 28 consecutive days, also referred to as one cycle. Additional cycles can continue as long as clinical benefit is confirmed by an investigator, and consent is maintained. There will be a screening visit, study visit on day 1 of each cycle, withdrawal visit within 42 days of stopping treatment, and a follow-up visit every 6 months for up to 18 months after stopping treatment. This results in a minimum of 6 study visits for the completion of one 28-day cycle of ivosidenib. One additional study visit will be added on day one of each additional cycle of treatment. Study visits will include a electrocardiogram (ECG), physical exam, tumor assessment, and blood and urine analyses. If at any point ivosidenib is made available as a medical prescription at the patient's site, patients will be withdrawn from this clinical trial and patients will be followed to collect data on overall survival.

Outcome Measures
Primary Outcome Measures
- Number of Adverse Events (AEs) from Day 1 of Cycle 1 through 28 days after last treatment [Day 1 of cycle 1, Day 1 of each consecutive cycle, 28 days after last treatment]
AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. All reported AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA), using the latest version. All reported AEs will be coded using the Medical Dictionary for Regulatory Activities (MedDRA), using the latest version.
- Number of Serious Adverse Events (SAEs) from Day 1 of Cycle 1 through study termination or withdrawal of consent, whichever comes first [Day 1 of cycle 1, Day 1 of each consecutive cycle, 28 + 14 days (maximum) after last treatment, 6 months after last treatment, 12 months after last treatment, 18 months after last treatment]
SAEs related to study drug will be collected irrespective of the time of onset. AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0.
- Number of QT prolongation events during electrocardiogram (ECG) assessed as Grade 2 or worse occurring from Day 1 of Cycle 1 through 28 days after last treatment [Day 1 of cycle 1, week 2 of cycle 1, week 3 of cycle 1, Day 1 of each consecutive cycle, 28 days after last treatment]
QT interval, using Fridericia's formula [QTcF], to average QTc interval > 480 to 500msec (Grade 2) or worse, as seen during an ECG. This is classified as an Adverse Event of Special Interest (AESI) for this study.
- Change in Eastern Cooperative Oncology Group (ECOG) performance status (PS) score from baseline to worst value out of the post-baseline assessments. [Screening visit, Day 1 of cycle 1, Day 1 of each consecutive cycle, 28 + 14 days (maximum) after last treatment]
ECOG PS scoring consists of Grade 0 - 5, with 0 being the patient is fully active and 5 being the patient is dead. Descriptive statistics of ECOG PS over time will be summarized by frequency. Shift tables may be provided for ECOG PS from baseline to worst value of post-baseline assessments.
- Number of Adverse Events (AEs) leading to discontinuation or death from day 1 through 28 days after the last treatment [Day 1 of cycle 1, Day 1 of each consecutive cycle, 28 days after last treatment]
Total number of AEs that result in discontinuation from treatment or death. AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0.
- Total laboratory abnormalities using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 grading scale or the low/normal/high classifications based on laboratory normal ranges. [Screening visit, Day 1 of cycle 1, Day 1 of each consecutive cycle, 28 + 14 days (maximum) after last treatment]
Listing of all laboratory hematology, coagulation, and chemistry data with values flagged as abnormal to show the corresponding NCI-CTCAE grades and the classifications relative to the laboratory normal ranges.
- Change from baseline to the worst on-treatment value of laboratory abnormalities. [Screening visit, Day 1 of cycle 1, Day 1 of each consecutive cycle, 28 + 14 days (maximum) after last treatment]
Abnormalities will be classified by using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 grading scale or the low/normal/high classifications based on laboratory normal ranges. Shift tables using NCI-CTCAE grades to compare baseline to the worst on-treatment value will be used. For laboratory tests, including hematology, coagulation, and chemistry, where NCI-CTCAE grades are not defined, shift tables using the low/normal/high [low and high] classification to compare baseline to the worst on treatment may be generated. On-treatment is considered from Day 1 of Cycle 1 through 28 days after the last dose.
- Number of patients with vital sign values outside limits of the normal range at each time point. [Screening visit, Day 1 of cycle 1, Day 1 of each consecutive cycle, 28 + 14 days (maximum) after last treatment]
Vital signs include systolic and diastolic blood pressure, heart rate, respiratory rate, and temperature.
- Mean change from baseline values to the worst on-treatment value of patients with vital signs outside limits of the normal range [Screening visit, Day 1 of cycle 1, Day 1 of each consecutive cycle, 28 + 14 days (maximum) after last treatment]
On-treatment is considered from Day 1 of Cycle 1 through 28 days after the last dose. Vital signs include systolic and diastolic blood pressure, heart rate, respiratory rate, and temperature.
Secondary Outcome Measures
- Progression-free survival (PFS) time beginning at screening [through 28 days after last treatment]
PFS is defined as the time from the date of enrollment to the date at which the disease escalates or progresses. It will be assessed using the Kaplan-Meier (KM) method curves and estimates. This will be based on tumor assessments conducted by the investigator according to local clinical practice.
- Overall survival (OS) [through 28 days after last treatment]
OS is defined as the time from date of enrollment to the date of death due to any cause. It will be assessed using the Kaplan-Meier (KM) method curves and estimates.
- Duration of response (DOR) [through 28 days after last treatment]
DOR is defined as the time from the date of response to either progression or death. It will be assessed using the Kaplan-Meier (KM) method curves and estimates. This will be based on tumor assessments conducted by the investigator according to local clinical practice.
- Time to response (TTR) [through 28 days after last treatment]
TTR is defined as the time from the date of enrollment to the date of response. It will be assessed using the Kaplan-Meier (KM) method curves and estimates. This will be based on tumor assessments conducted by the investigator according to local clinical practice.
- Change from baseline of Quality of life scores [through 28 days after last treatment]
Measured by the validated European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire - Cholangiocarcinoma and Gallbladder Cancer Module (QLQ-BIL21). EORTC QLQ-BIL21, will be evaluated for patients with a baseline assessment and at least 1 post-baseline QLQ-BIL21 assessment that generates a score. Change from baseline for each time point, will be summarized using descriptive statistics.
- Proportion of days at home or hospital for all patients [through 28 days after last treatment]
- Change from baseline of health economic measures, as assessed by the 5-level EuroQol 5-dimensional questionnaire (EQ-5D-5). [through 28 days after last treatment]
Health economic measures, as assessed by the EQ-5D-5L, will be evaluated for patients with a baseline assessment and at least 1 post-baseline EQ-5D-5L assessment that generate a score. Change from baseline scores for each time point will be quantified with descriptive statistics.
