Why
  1. The study's listed conditions name Leishmaniasis, Cutaneous, a narrower term within Leishmaniasis.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

A clinical trial to asses efficacy and safety of Transition-state Analog Inhibitor of Human Purine Nucleoside Phosphorylase for topical use associated standard antimonial in the treatment of Cutaneous Leishmaniasis in Bahia, Brazil.

Read the detailed description

The treatment of cutaneous leishmaniasis caused by L. braziliensis in Brazil with pentavalent antimony is associated with a high rate of failure, reaching up to 45% of cases. Additionally, pentavalent antimony is only administered by parenteral route with important toxicity and ulcer lesion healing takes a long time, from 2 to 3 months.

So, this randomized and controlled clinical trial was designed to compare the efficacy and safety of standard antimonial (20mg/day /kg for 20 days) associated with Transition-state Analog Inhibitor of Human Purine Nucleoside Phosphorylase for topical use versus standard antimonial (20mg/kg/day for 20 days) associated with placebo for topical use in the treatment of Cutaneous Leishmaniasis and Early Cutaneous Leishmaniasis caused by L. braziliensis in the endemic area of Corte de Pedra, Bahia, Brazil.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Newly diagnosed (untreated) cutaneous leishmaniasis or early cutaneous leishmaniasis with localized lesions and a positive culture or diagnosed by polymerase chain reaction (PCR) methods or by intradermal skin testing (Montenegro test).
  • Number of lesions: 1 to 3 ulcerative lesions.
  • Lesion´s diameter: 1 to 5 cm.
  • Disease duration: up to three months.

Exclusion criteria

Exclusion Criteria:

  • , alanine aminotransferase >3 times
  • Serum creatinine or blood urea nitrogen >1.5 times upper limit of normal range
  • Evidence of serious underlying disease (cardiac, renal, hepatic or pulmonary)
  • Immunodeficiency or antibody to
  • Any non-compensated or uncontrolled condition, such as active tuberculosis, malignant disease, severe malaria, HIV, or other major infectious diseases
  • Lactation, pregnancy (to be determined by adequate test) or inadequate in females of for treatment period plus 2 months
  • Negative parasitology (aspirate//PCR) or negative Montenegro test
  • Any history of prior anti-leishmania therapy
  • Any condition which compromises ability to comply with the study procedures
  • Lack of ability or willingness to give (patient and/or parent / legal representative)
  • Anticipated non-availability for study visits/procedure
Terms in these criteria, in plain language(7)

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.

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.

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.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

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.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

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.

What researchers measure

Primary outcomes

  1. Cure rate or complete cicatrization of the ulcer.

    Bidirectional measurements of ulcers will be taken of the patients' lesions at the initial visit, and at each follow-up visit with standardized caliper. The area involved will be calculated as the product of the two measurements. All lesions will be categorized as either active or healed (cured) at follow-up visits. Only lesions with complete re-epithelialization, without raised borders, infiltrations or crusts will be considered healed. Evaluation of the lesions will be performed by 2 clinicians who will be unaware of the group assignment of all patients.

    Time frame: 6 months after treatment

Secondary outcomes

  1. Initial cure rate or complete cicatrization of the ulcer.

    Bidirectional measurements of ulcers will be taken of the patients' lesions at the initial visit, and at each follow-up visit with standardized caliper. The area involved will be calculated as the product of the two measurements. All lesions will be categorized as either active or healed (cured) at follow-up visits. Only lesions with complete re-epithelialization, without raised borders, infiltrations or crusts will be considered healed. Evaluation of the lesions will be performed by 2 clinicians who will be unaware of the group assignment of all patients.

    Time frame: 2 months after treatment

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 26, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
