Details and patient eligibility

About

The objectives of the study are to evaluate the safety and efficacy of open label treatment with WR 279,396 (topical paromomycin & gentamicin) in patients with non-complicated, non-severe cutaneous leishmaniasis (CL).

Full description

Patients with suspected CL will be screened up to a 14 day period for eligibility including parasitology for confirmation of ulcerative CL. Recruitment will primarily be from patients exposed to leishmaniasis. A target enrollment of 30 patients will receive WR 279,396 (15% paromomycin + 0.5% gentamicin topical cream) once daily for 20 days.

The index lesion and all other ulcerated lesions will be assessed for clinical response by measurement of the length and width of area of ulceration. A lesion will be considered to be completely cured if 100% re-epithelialization is observed. Non-ulcerated lesions will also be measured to monitor the total area of exposure of lesions to study drug and will be evaluated for cure.

Inclusion criteria

To be eligible for the study, patients must:

Be male or females ages 2 to 80 years of age, inclusive.
Have non-complicated, non-severe CL.
Be able to give written informed consent or by their legal representative.
Have a diagnosis of CL in at least one lesion by at least one of the following methods: 1) positive culture for promastigotes; 2) microscopic identification of amastigotes in stained lesion tissue and/or 3) by positive polymerase chain reaction (PCR). Patients who have a prior diagnosis of CL within 30 days of the start of treatment are eligible without a confirmatory test during screening.
Have at least one ulcerative lesion ≥ 1 cm and < 5 cm, that meets the criteria for an index lesion.
Be willing to forego other forms of treatments for CL including other investigational treatment during the study.
In the opinion of the investigator, be capable of understanding (or their legal representative) and complying with the protocol.
Expect to be located in the area of the clinical site for at least the duration of the screening, 20-day treatment period, and for the followup visits at Days 28 +/- 2 days, 42 +/- 7 days and 100 +/- 14 days.
If female and of child-bearing potential, have a negative serum or urine pregnancy test during screening and agree to use an acceptable method of birth control during the treatment phase and for 1 month after treatment is completed.

Exclusion criteria

Also, to be eligible for the study, patients must not:

Have a prior diagnosis of leishmaniasis where all lesions had healed.
Have only a single lesion whose characteristics include any of the following: verrucous or nodular lesion (non-ulcerative), lesion <1 cm in its greatest diameter, lesion in a location that in the opinion of the Investigator is difficult to maintain application of study drug topically.
Have a lesion due to leishmania that involves the mucosa or palate.
Have signs and symptoms of disseminated disease.
Be a female who is breast-feeding.
Have an active malignancy or history of solid, metastatic or hematologic malignancy with the exception of basal or squamous cell carcinoma of the skin that has been removed.
Have significant organ abnormality, chronic disease such as diabetes, severe hearing loss, evidence of renal or hepatic dysfunction, myasthenia gravis, parkinsonism, impairment of the eighth cranial nerve or clinically significant levels of creatinine, AST, or ALT in the judgment of the investigator.
Have received treatment for leishmaniasis (except mercurochrome or local antiseptics) including any medication with pentavalent antimony including sodium stibogluconate (Pentostam), meglumine antimoniate (Glucantime); amphotericin B (including liposomal amphotericin B and amphotericin B deoxycholate); WR 279,396; or other medications containing paromomycin (administered parenterally or topically) within 56 days of starting study treatments, or methylbenzethonium chloride (MBCL); or local or systemic antibiotics of the following families (penicillin, betalactamics, cyclines, synergistin, macrolides, lincosamides, fusidic acid, mupirocin) within 8 days of starting study treatments.
Have history of known or suspected hypersensitivity or idiosyncratic reactions to aminoglycosides.
Have any other topical disease/condition which would interfere with the objectives of this study.
