A Study to Evaluate Abemaciclib in Advanced Biliary Tract Carcinoma

Phase 2

Terminated

Conditions: Biliary Tract Carcinoma

Interventions: Drug: Abemaciclib

Registration Number: NCT04003896

Lead Sponsor: Milton S. Hershey Medical Center

Brief Summary: The prognosis of patients with recurrent, late-stage inoperable, or progressed biliary tract carcinoma (BTC) is generally poor. The goal of this clinical study is to determine the effectiveness and safety of abemaciclib in patients with late-stage or progressed BTC that has failed one line of chemotherapy.

Detailed Description: Biliary Tract Carcinoma (BTC) is a leading cause of cancer-related mortality. The newly developed small molecule inhibitor of cyclin-dependent kinases (CDK4 and CDK6), abemaciclib, provides a new opportunity of treating patients with BTC. The goal of this clinical study is to determine the efficacy and safety of abemaciclib in patients with advanced or metastatic BTC that has progressed or intolerant to one or more lines of systemic therapy, or treatment-naïve subjects who either decline or being considered not a good candidate first-line systemic chemotherapy per the opinion of the treating physician.

The investigator's objectives for this study are as follows:

Primary Objectives:

• To estimate the objective response rate (ORR)

Secondary Objectives:

* To determine progression free survival (PFS)

* To determine the disease control rate (DCR)

* To determine the overall survival (OS) rate at 6 and 12 months

* To determine quality of life (QoL) using EORTC-QLQ-C30

Study & Design

Study Type: INTERVENTIONAL

Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
Abemaciclib	Abemaciclib	Abemaciclib will be given as a single oral agent A sample size of 10 subjects is determined to be minimally sufficient for these pilot study objectives. The starting dose will be 200 mg twice daily. Dosing will continue daily for 28 days, this being one cycle. There will be no protocol scheduled hiatus and daily dosing will be continuous unless there is unacceptable toxicity, disease progression, or death.

Primary Outcome Measures

Name	Time	Method
Overall Response Rate	no longer than 7 months	overall response rate (ORR) is defined as the percentage of subjects with evidence of a confirmed complete response (CR) or partial response (PR) as per Response Evaluation Criteria In Solid Tumors (RECIST) Version 1.1.The scale of ORR ranges from 0% to 100%, where 0% indicates no subjects achieved CR or PR, and 100% indicates all evaluable subjects achieved CR or PR.

Secondary Outcome Measures

Name	Time	Method
Progression-free Survival	through study completion, an average of 2 years	the time interval from date of first dose of study drug to first documented disease progression or death from any cause, whichever occurs first. The PFS scale ranges from 0 days (for immediate progression or death) to the longest observed duration without progression or death.
Disease Control Rate	no longer than 7 months	Disease Control Rate (DCR) is defined as the proportion of subjects who achieve a Complete Response (CR), Partial Response (PR), or Stable Disease (SD) as determined by the Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1. The scale of DCR ranges from 0% to 100%, where 0% indicates no subjects achieved CR, PR, or SD, and 100% indicates all evaluable subjects achieved disease control (CR, PR, or SD). Subjects who do not have sufficient data to determine response status are excluded from the denominator.
Overall Survival Rate	up to 12 months	Overall survival rate (OSR) is is typically reported as a percentage (%), representing the proportion of subjects who are alive at a specific time point after receiving the first dose of the study drug. The scale of Overall Survival Rate (OSR) ranges from 0% to 100%, where 0% indicates that none of the study participants survived for the specified period after the first dose of the study drug, and 100% indicates that all participants are alive at that time point. A higher OSR percentage suggests a greater proportion of subjects who have survived, reflecting the potential effectiveness of the treatment under investigation. Overall Survival at 12 months is not available. Data were only collected up to 6 months.
Quality of Life Score	Assessment at the end of treatment with Abemaciclib, approximately 60 days after starting treatment.	Quality of Life (QoL) will be assessed from the date of baseline and then every 4 weeks using the EORTC QLQ-C30. The QLQ-C30 comprises both multi-item scales and single-item measures, including a global health status/QoL scale, five functional scales, three multi-item symptom scales, and six single-item scales. For the multi-item scales, the raw score (RS) is calculated by taking the mean of the individual item scores. A linear transformation is then applied to standardize the raw score, resulting in a standardized score ranging from 0 to 100, where a score of 0 indicates the worst possible QoL and a score of 100 indicates the best possible QoL.
