  Description
WR 279,396 Topical Treament

WR 279,396 topical cream (15% paromomycin + 0.5% gentamicin topical cream)

WR 279,396 topical cream: WR 279,396 is a topical antibiotic cream containing 15% paromomycin and 0.5% gentamicin that will be applied to each lesion once a day and covered with a sterile gauze and tape dressing.

Paromomycin Alone Topical Treatment

Paromomycin Alone topical cream (15% paromomycin topical cream)

Paromomycin Alone topical cream: The antibiotic paromomycin 15% in the same topical cream used in arm 1 will be applied to lesions daily and covered with a protective sterile gauze and tape dressing.

Vehicle Placebo Cream

The cream base without the addition of paromomycin or gentamicin

Vehicle placebo cream: Applied daily to cutaneous leishmaniasis lesions, primarily ulcerative, and covered with a protective, sterile gauze and tape dressing.
