Visceral leishmaniasis

Developing a new generation of treatments for one of the world’s leading parasitic killers

  • Overview
  • Facts
  • Projects & achievements
  • Target product profiles

We delivered two new treatments using existing drugs to make treatment shorter, safer, and more effective. We are now working to revolutionize the standard of care, advancing an unprecedented portfolio of all-new potential drugs to treat people suffering from all forms of the disease.

Visceral leishmaniasis – also known as kala-azar – causes fever, weight loss, spleen and liver enlargement, and, if not treated, death. HIV infection increases the severity of the disease, heightening people’s risk of dying from visceral leishmaniasis.

Post-kala-azar dermal leishmaniasis (PKDL) – a complication of visceral leishmaniasis that appears as a rash or skin condition months or years after successful visceral leishmaniasis treatment – is not deadly but can be disfiguring and stigmatizing.

In some regions affected by visceral leishmaniasis, treatments are poorly tolerated and lengthy, and can be toxic, painful, and costly.

‘I stopped going out, stopped playing with my friends fearing they would tease me. People told me my scars were permanent and would ruin my life as I will not get married. I don’t want to go through the trauma I underwent twice due to this disease’

What we have achieved

We have delivered new treatments using existing drugs to make treatments shorter, safer and more effective.

Clinical trials

New VL treatments (Latin America)

Safe and shorter treatment for VL patients. In Brazil, DNDi collaborated with partners to implement a large clinical trial to assess a new combination therapy against current treatments. Liposomal amphotericin B was shown to be efficacious and safer for the treatment of visceral leishmaniasis patients in Brazil.

New VL treatments (South Asia)

Overcoming drug resistance and severe side effects. A DNDi-led consortium identified new combinations with cure rates above 95% to replace treatments with severe side effects or poor efficacy due to drug resistance. Trials generated the key evidence needed for policy change in South Asia.

SSG&PM (East Africa)

Shorter, more affordable treatment. DNDi-led clinical trials showed a combination of sodium stibogluconate (SSG) and paromomycin was safe and as effective as treatment with SSG alone. The more affordable combination is easier for patients and cuts treatment time by nearly half.

What we’re doing for people with visceral leishmaniasis

We are working to deliver better combination treatments and new drugs. Together with our partners, we have built an unprecedented portfolio of six new chemical classes, with different mechanisms of action against Leishmania parasites.

The long-term goal: entirely new, oral drugs

Our goal is to radically transform therapy by developing patient-friendly, simple oral therapies that are short, affordable, safe and effective in children and adults in all regions. A novel consortium bringing together pharmaceutical industry, academia, research institutes, and PDPs is building an unprecedented portfolio of promising drug candidates.

Clinical trials

New treatments for PKDL

PKDL could jeopardize elimination efforts. We have shown that PKDL patients can infect sandflies, potentially sustaining the cycle of transmission even when small numbers of visceral leishmaniasis cases are reported. This study was conducted in Bangladesh and similar infectivity studies will be performed in Sudan.

Clinical trials

New treatments for HIV/VL

New hope for a deadly coinfection. Following promising studies in Ethiopia – now being replicated in India – a new and improved treatment option for visceral leishmaniasis in people co-infected with HIV may be on the horizon.
