Detailed Description

This study is a Phase 4, open-label, single group study in which at least 40 adult patients undergoing miltefosine treatment for mucocutaneous leishmaniasis will be assessed by digital 12-lead electrocardiogram (ECG) for prolongation of the corrected QT (QTc) interval. Potential subjects diagnosed with mucocutaneous leishmaniasis who are planning to undergo miltefosine treatment will be informed about the study and undergo the informed consent process. After obtaining informed consent, subjects will be screened over a 14-day period for eligibility by medical history including leishmaniasis diagnostics, physical examination, clinical laboratory measurements [chemistries: alanine aminotransferase (ALT), total bilirubin, creatinine, magnesium, calcium, potassium, sodium; hematology: white blood cell (WBC) count, hemoglobin, platelet count; and a pregnancy test if female], ECG, and medication use in the 28-day period before starting treatment. If eligible for the study, the subject will receive miltefosine for 28 days at a target dose of approximately 2.5 mg/kg/day. Screening and enrollment into the study will continue until at least 10 females and up to 30 males complete the study and are considered evaluable (provide Day 28 ECGs and pharmacokinetic (PK) samples and complete at least 25 of 28 days of miltefosine treatment). Vital signs will be collected weekly during treatment. Chemistries and hematology will be repeated at study Days 14 (mid-treatment) and 28 (end of treatment). A pregnancy test (if applicable) will be repeated at Day 28. ECGs (12-lead) will be repeated at Days 14 and 28. Blood will be drawn for PK assessments on Days 14 and 28 within 15 minutes of the final ECG. Adverse events (AEs) and concomitant medication use will be collected during treatment. If on Day 28, clinically significant abnormalities are observed by ECG, then a repeat ECG and PK blood draw will be performed at Day 42 (2 weeks after completing treatment). AEs and concomitant medication use will also be collected in any subject coming back for the Day 42 visit. Digital ECGs (12-lead) will be collected in triplicate at each time point over a period not to exceed 1 hour. During treatment, ECGs will be collected 4 hours after a dose (approximate Tmax).

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.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
mean value of corrected QT interval
Time Frame: up to 2 weeks after end of treatment
QTcF
up to 2 weeks after end of treatment

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
number of patients with adverse events
Time Frame: up to 2 months after end of treatment
AEs and SAEs
up to 2 months after end of treatment
