Brief Summary:
The overall objective of this trial is to identify a safe and effective combination, (coadministration) short course treatment for the treatment of visceral leishmaniasis which could be easily deployed in a control programme and will reduce the risk of parasite resistance occurring.
Safety and tolerability should be such that the combination can be easily deployed.
Safety and tolerability should be such that the combination can be easily deployed.
Detailed Description:
New, effective, less toxic and simplified treatments are urgently needed to replace or complement the few currently available drugs to treat visceral Leishmaniasis. An interim strategy and one which will slow the emergence of resistant parasite strains is to use coadministration of currently available drugs.
In India, first line treatment is now amphotericin B which is administered as an intravenous infusion, on alternate days over a 4 week period. A liposomal formulation of amphotericin B, AmBisome, is also available, and is substantially less nephrotoxic than amphotericin B, but is expensive.
It is acknowledged that AmBisome is the most effective therapy for visceral leishmaniasis, but it's high cost has hampered implementation. Use as part of a combination treatment, potentially as a single, lower dose, could reduce treatment costs considerably and thereby increase access for patients.
Two new treatments have recently been licensed in India for the treatment of patients with VL,
* Paromomycin administered as an intramuscular injection, once daily for 21 days
* Miltefosine administered as an oral tablet, once daily for 28 days. These drugs are now being used as monotherapy with high risk of emergence of resistant parasites. With price reduction for AmBisome, preferential pricing for Miltefosine and the concern for emergence of resistant parasites due to monotherapy, it is time to move rapidly toward obtaining definitive data for making recommendations on combination therapy as soon as possible, before these valuable drugs become useless. The present protocol will be a definitive Phase-III trial with the aim that at the end of this trial, strong evidence-based recommendations on combination therapy with available drugs can be made to Authorities in the Indian sub-continent. This protocol will evaluate various combinations of the three drugs; AmBisome, Paromomycin and Miltefosine at reduced total dosage and in shorter courses, against the present standard treatment with amphotericin B deoxycholate.
