L-carnitine vs Placebo for the Treatment of Muscle Cramps After Imatinib in Gastrointestinal Stromal Tumors

July 10, 2020 updated by: Yoon-Koo Kang, Asan Medical Center

Phase III Study of L-carnitine vs Placebo for the Treatment of Muscle Cramps After Imatinib in Patients With Gastrointestinal Stromal Tumors (GISTs) (Single-center Study)

we aim to evaluate the efficacy of L-carnitine for the treatment of muscle cramps after imatinib in patients with GIST and apply in the future.

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

One of the most common side effects of imatinib treatment, muscle cramps occur in about 30% of patients with gastrointestinal stromal tumor (GIST) receiving treatment with imatinib.

It affects the quality of life (QoL) of patients and could also be a factor that affects compliance with treatment. Some studies suggest that L-carnitine may improve muscle cramps associated with cirrhosis or hemodialysis. However, the efficacy of L-carnitine for muscle cramps occurring after imatinib treatment has yet to be reported. Thus, we aim to evaluate the efficacy of L-carnitine for the treatment of muscle cramps after imatinib in patients with GIST and apply in the future.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
ACTIVE_COMPARATOR: L-carnitine

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
Proportion of patients who have occurrence of muscle cramps ( numeric rating scale score > 4)
Time Frame: 4 weeks

Proportion of patients who have occurrence of muscle cramps ( numeric rating scale score > 4) decreased by less than 50% in 4 weeks excluding the first 4 weeks of drug administration

*numeric rating scale scores(range, 0-10) -> higher score is worse outcome
4 weeks

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
Change in average numeric rating scale scores of muscle cramps
Time Frame: 4 weeks

Change in average numeric rating scale scores(range, 0-10) of muscle cramps in 4 weeks excluding the first 4 weeks of drug administration

*numeric rating scale scores(range, 0-10) -> higher score is worse outcome
4 weeks
Rate of patients who have duration of muscle cramps (numeric rating scale score > 4)
Time Frame: 4 weeks

Rate of patients who have duration of muscle cramps (numeric rating scale score > 4)

that was decreased by more than 50% in next 4 weeks excluding the first 4 weeks of drug administration

*numeric rating scale scores(range, 0-10) -> higher score is worse outcome
4 weeks
questionnaire(Quality of Life)
Time Frame: 4 weeks
Evaluation of the change in the Quality of Life in 4 weeks
4 weeks
plasma concentration level
Time Frame: 1 year
Concentration evaluation of L-carnitine
1 year
recurrence rate
Time Frame: 1 year
Recurrence is defined as 1) frequency of muscle cramps (NRS > 4) becomes more than 50% of baseline and 2) frequency of muscle cramps (NRS > 4) get twice worse than most improved time (when evaluated every 4 weeks)
