Lymphatic filariasis

Finding a cure to end a disabling disease

We are working to develop a safe, effective, affordable treatment to help eliminate lymphatic filariasis. 

Also known as elephantiasis due to the extreme swelling (lymphedema) that can result from the disease, lymphatic filariasis is caused by parasitic worms spread by the bites of infected mosquitoes. While people of all ages can get the disease, it’s most painful and disfiguring effects are only seen years after infection – and can result in social stigma, chronic ill health, and lifelong disability.  

Mass drug administration over many years reduces transmission of the disease, but these treatments do not kill adult worms or reverse the long-term effects of infection. 

India has committed to eliminating lymphatic filariasis by 2027 – and new treatments that kill both adult and juvenile worms could help the country achieve and sustain elimination.

‘I suffer from really painful attacks from the swelling in my legs.’

Tilottama from Odisha, India

What we have achieved

R&D progress in the development of a macrofilaricide (a treatment able to kill adult worms) could benefit all filarial diseases. After testing oxfendazole for river blindness and other filarial diseases as part of the eWHORM consortium, DNDi is supporting partners now working to test the drug against lymphatic filariasis.

What we are doing for people with lymphatic filariasis

We aim to test and develop a new treatment that can prevent disability and help eliminate lymphatic filariasis as a public health problem.

Clinical trials

Oxfendazole

We are working with the Indian Council of Medical Research to test oxfendazole as a potential treatment for lymphatic filariasis. Already being tested against other helminth infections, oxfendazole could transform treatment for LF – and help eliminate it altogether – if proven effective.

Clinical trials

Paediatric ivermectin (IVM-KIDS)

Ivermectin is a critical drug against parasitic worm diseases – but a lack of data and suitable paediatric formulation leave it out of reach of children who need it. We are working with partners to develop and test a safe, child-friendly formulation of ivermectin.
