CLINICAL TRIALS PROFILE FOR PAROMOMYCIN SULFATE

All Clinical Trials for PAROMOMYCIN SULFATE

Trial ID	Title	Status	Sponsor	Phase	Start Date	Summary
NCT00000771 ↗	A Double-Blind, Placebo-Controlled Trial of Paromomycin for Treatment of Cryptosporidiosis in Patients With Advanced HIV Disease and CD4 Counts Under 150 Cells/mm3	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	Phase 2	1969-12-31	To determine the effectiveness of oral paromomycin sulfate for 21 days compared to placebo in the treatment of cryptosporidiosis in patients with HIV infection. To evaluate the safety of oral paromomycin at two different doses. To explore whether paromomycin administered over a longer period provides additional benefit. In previous studies, patients with cryptosporidiosis demonstrated dramatic improvement with paromomycin therapy.
NCT00001128 ↗	Treatment of Chronic Cryptosporidiosis in AIDS Patients	Terminated	Genetics Institute	N/A	1969-12-31	The purpose of this study is to see if it is safe and effective to add interleukin-12 (IL-12) to the standard drug combination (paromomycin plus azithromycin) used to treat cryptosporidiosis in AIDS patients. Doctors would like to find out if the combination of IL-12, paromomycin, and azithromycin is more effective than paromomycin and azithromycin alone. Cryptosporidiosis is a type of opportunistic (AIDS-related) infection seen in HIV-positive patients as their immune systems weaken. It is caused by a parasite that invades the intestinal tract, and it can cause watery diarrhea, stomach cramps, an upset stomach, or a fever. Antibiotics (paromomycin and azithromycin) are usually used to treat cryptosporidiosis. In this study, doctors will look at the effectiveness of using IL-12. IL-12 is a type of protein naturally produced by certain types of cells of the immune system and is believed to be important for immune function. Doctors hope that IL-12 can help boost the immune system in fighting cryptosporidiosis.

NCT01050777 ↗	Efficacy of Topical Liposomal Form of Drugs in Cutaneous Leishmaniasis	Completed	Center for Research and Training in Skin Diseases and Leprosy	Early Phase 1	2011-03-01	Leishmaniasis with diverse clinical manifestations is caused by different species of Leishmania and is endemic in many countries. Although Cutaneous Leishmaniasis (CL) is a self-healing disease, but it takes a long time to heal. Pentavalent antimonials are still the first-line treatment of CL which needs multiple injections, are painful and as such not tolerated by most of the patients, in addition available treatments are not always effective and resistance is reported. Paromomycin sulfate (PM) reported to show anti-Leishmania activity against both CL and visceral leishmaniasis (VL) since 1960s. Therapeutic strategy with high efficacy is urgently needed especially for Anthroponotic Cutaneous Leishmaniasis (ACL). Liposomes are lipid bilayer molecules which entrap water-soluble molecules in their internal water compartment and water-insoluble ones into their lipid bilayers. Liposomes, in proper formulations and sizes, deliver drugs to the skin based on the similarity of the bilayers structure of lipid vesicles to that of natural membrane and target the macrophages within dermis. Several lipid-based formulations have been developed to treat experimental leishmaniasis. Recently different doses of liposomal formulation of PM and liposomal formulation of Glucantime were prepared and showed high efficacy in vivo against L. major infection in BALB/c mice. In this study the efficacy of liposomal formulation of PM or liposomal formulation of Glucantime in combination with systemic Glucantime in the treatment of ACL parasitologically proven patients will be evaluated. The clinical trial will be carried out according to the International approved GCP (Good Clinical Practice) guide lines.
