Study summary

This study is a Phase 4, open-label, single group study in which at least 40 adult patients undergoing miltefosine treatment for mucocutaneous leishmaniasis (CL and ML) will be assessed by 12-lead ECG for prolongation of the corrected QT interval

Read the 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).

Terms in these criteria, in plain language(10)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
