What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Definitive Cure

    definitive cure at 12 months after treatment onset, defined as clinical cure (100% lesions resolution) and no additional PKDL treatment between end of therapy and 12 months follow-up assessment.

    Measured: 12 months follow-up assessment

  2. Incidence of treatment-emergent adverse events

    Frequency of SAE from start of treatment to 12 months follow-up Frequency and severity of all adverse events Frequency and severity of adverse events that lead to treatment discontinuation

    Measured: from start of treatment to 12 month follow-up

Secondary outcomes (5)
  1. Pharmacokinetics of Miltefosine

    To assess the maximal accumulation (Cmax) of Miltefosine in the skin at the end of treatment and correlate it with achieved plasma concentrations.

    Measured: Miltefosine concentration in the skin will be measured at day 14 and day 42 for MF+PM arm and at day 7 and day 28 for Ambisome+MF arm. Miltefosine concentration in the blood will be measured at day 1, day 7, day 14, day 28, day 42 and 3 month

  2. Pharmacokinetics of Amphotericin B (MF + Ambisome arm only)

    To assess the maximal accumulation (Cmax) of Amphotericin B in the skin at the end of treatment and correlate it with achieved plasma concentrations.

    Measured: Amphotericin B concentration will be measured in the skin at day 7 and day 28. Amphotericin B concentration in the blood will be measured at day 1 and day 7.

  3. Pharmacokinetics of Paromomycin (MF + Paromomycin arm only)

    To assess the maximal accumulation (Cmax) of Paromomycin in the skin at the end of treatment and correlate it with achieved plasma concentrations.

    Measured: Paromomycin concentration will be measured in the skin at day 14 and day 42. Paromomycin concentration in the blood will be measured at day 1 and day 14.

  4. Immune Response

    To assess the change in immune response during and after end of treatment by measuring cytokines profiles level in the peripheral blood.

    Measured: At screening, at day 42 (end of treatment) and at 6 month follow-up

  5. Parasite quantification in blood and skin

    Parasites will be quantified in blood and skin, by microscopy and qPCR, to assess the clearance before and after treatment.

    Measured: At screening, day 42 (end of treatment), 3 month follow-up, 6 month follow-up and 12 month follow-up.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Paromomycin, Ambisome and Miltefosine in people with PKDL - Post-Kala-Azar Dermal Leishmanioid, run by Drugs for Neglected Diseases at 1 site in Sudan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 18 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sudan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Gina M Ouattara, manager (+254 20 3995000, gmouattara@dndi.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Definitive Cure (time frame: 12 months follow-up assessment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03399955, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jan 2020.
