We’re investigating a new treatment for this debilitating disease of the lymph system
Lymphatic filariasis (also known as elephantiasis) is a painful and debilitating disease that affects the lymph system. It is caused by a microscopic worm – Wuchereria bancrofti, Brugia malayi and B. timori – transmitted to people through the bite of infected mosquitos. Inside the human body, the parasitic worms travel through the lymph system, often undetected, eventually causing abnormal enlargement in the arms, legs and genitalia.
People are suffering from lymphatic filariasis in tropical and sub-tropical regions throughout the world, particularly in Africa, south and east Asia and some Pacific islands.

Current community-directed treatments for lymphatic filariasis include albendazole, which stops the worms from absorbing sugar, alone or in combination with ivermectin (an anti-parasitic drug) or diethylcarbamazine (which inhibits the metabolism of a specific omega-6 fatty acid in the parasites), depending on the presence of co-endemic infections.
The treatment we are studying for lymphatic filariasis is moxidectin, an anti-microfilarial medicine. We are collaborating in a Phase 2/3 lymphatic filariasis study being conducted in Cote D’Ivoire by the Death to Onchocerciasis and Lymphatic Filariasis (DOLF) project run by Washington University, St. Louis, USA. This study was initiated in Q3 2020 and will evaluate the safety and efficacy of moxidectin in combination with albendazole and diethylcarbamazine.
