Real-world Evidence Study EvaLuating PAtient-Reported Outcomes With XERMELO (RELAX)

July 15, 2024 updated by: TerSera Therapeutics LLC

An Observational Study to Evaluate the Real-world Experience of Patients Who Are Initiating Treatment With Telotristat Ethyl (XERMELO™)

The primary objective of the study is to estimate the proportion of carcinoid syndrome (CS) patients who are satisfied with their overall symptom control, 6 months after initiating treatment with telotristat ethyl (XERMELO).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will evaluate patient-reported outcomes for adults initiating telotristat ethyl (XERMELO) for carcinoid syndrome diarrhea (CSD) not adequately controlled by somatostatin analogs in US clinical practice. The primary objective is satisfaction with overall CS symptom control 6 months after starting XERMELO. Secondary objectives will evaluate satisfaction with control of CSD and flushing, CS symptoms, work productivity and activity impairment, SSA use, and weight. This study will provide real-world patient-reported outcomes in CS with XERMELO treatment for at least 6 months.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Patients Who Are Satisfied With Their Overall Symptom Control
Time Frame: Baseline to 6 months
The percentage of CS patients who are satisfied with their overall symptom control, 6 months after initiating treatment with telotristat ethyl (XERMELO). Satisfaction with how Xermelo has controlled diarrhea, flushing, and overall CS symptoms was assessed at the initial 6-month follow-up. The questionnaire allowed participants to choose a response on a 5-level Likert scale ranging from "Very dissatisfied" (level 1) to "Very satisfied" (level 5). For the assessments of satisfaction with control of diarrhea and flushing, "Not applicable" (level 0) was a response option for participants who do not have the particular symptom that is being assessed.
Baseline to 6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Patients Reporting Satisfaction of CS-related Diarrhea Control
Time Frame: Baseline to 6 months
Estimate percentage of patients reporting satisfaction with CS-related diarrhea control from Baseline to 6 months after starting Xermelo. At baseline participants were asked, "Currently, how satisfied are you with how your diarrhea is controlled?" At the 6-month follow-up survey, participants were asked, "Currently, how satisfied are you with how Xermelo has controlled your diarrhea?"
Baseline to 6 months
Percentage of Patients Reporting Satisfaction of CS- Related Flushing Control
Time Frame: Baseline to 6 months
Estimate percentage of patients reporting satisfaction with CS-related flushing control from Baseline to 6 Months. At baseline, participants who had reported flushing as a symptom were asked, "Currently, how satisfied are you with how your flushing is controlled?" At 6 months, participants who had reported flushing as a symptom at Baseline were asked, "Currently, how satisfied are you with how Xermelo has controlled your flushing?"
Baseline to 6 months
Number of Patients Reporting Reduction in Rescue SSA Use
Time Frame: Baseline to 6 months
Number of participants reporting a reduction in rescue SSA use at 6 months after initiating treatment with Xermelo.
Baseline to 6 months
Percentage of Patients Reporting Reduction in the Dose of Long-acting SSA Injection
Time Frame: Baseline to 6 months
Percentage of patients reporting a reduction in the dose of long-acting SSA injection 6 months after patients initiated treatment with Xermelo
Baseline to 6 months
Percentage of Patients Reporting Reduction in the Frequency of Long-acting SSA Injection
Time Frame: Baseline to 6 months
Estimate Percentage of Patients Reporting Reduction in the Frequency of Long-acting SSA Injection 6 months after patients initiated treatment with Xermelo
Baseline to 6 months
Percentage of Patients Reporting an Overall Improvement in CS Symptom Control Based on Patient Global Impression of Change (PGIC)
Time Frame: Baseline to 6 months
Estimate percentage of patients reporting an overall improvement in CS symptom control (diarrhea, flushing, frequency of BMs) after initiating Xermelo based on Patient Global Impression of Change (PGIC)
Baseline to 6 months
Percentage Change of Patients Who Had Reduction in Work-related Absenteeism, Presenteeism, Activity Impairment, and Overall Productivity Loss From Baseline to 6 Months After Initiating Telotristat Ethyl Based on WPAI-SHP
Time Frame: Baseline to 6 months
Estimate of the percentage of patients who had reduction in work-related absenteeism, presenteeism, activity impairment, and overall productivity loss based on Worker Productivity and Activity Impairment: Specific Health Problem v2.0 (WPAI- SHP). The percentage change was measured from baseline to 6 months after treatment with telotristat ethyl.
Baseline to 6 months
Percentage of Patients Reporting Weight Gain
Time Frame: Baseline to 6 months
Estimate of the percentage of patients reporting weight gain after initiating Xermelo therapy.
Baseline to 6 months
