Develop and register formulations of benznidazole for treating infants and children with Chagas disease
current phase of drug development
updated 1 Jun 2021
Treatment gap closed for children with Chagas disease
Until 2011, benznidazole, the main drug of choice for treating Chagas disease, was only available in an adult-strength tablet. Infants and children were treated with divided or crushed adult tablets, which was complicated for caregivers and resulted in inconsistent dosing.
The paediatric formulation of benznidazole is an affordable, easy to use, non-patented dispersible tablet designed for infants and children up to two years of age (less than 20 kg). It was added to the WHO Essential Medicines List for Children in 2013.
he tablet dissolves easily so that treating young children is simpler. There is no need to divide tablets, except for low birth weight babies weighing less than 2.5 kg. The paediatric formulation improves dosing accuracy, safety, and adherence to treatment.
- Indication: Chagas disease in children
- Dosage: Child-adapted dose of 12.5 mg per tablet (twice daily for 60 days)
Registered in Brazil in 2011
- First paediatric Chagas disease drug granted registration by Brazil’s National Health Surveillance Agency (ANVISA)
- Result of a three-year collaborative partnership, starting in 2008, between DNDi and Pernambuco State Pharmaceutical Laboratory (LAFEPE from Laboratório Farmacêutico do Estado de Pernambuco) of Brazil
Registered in USA in 2017
- Benznidazole is the first drug ever approved by the US FDA to treat Chagas disease
- The FDA approved benznidazole to treat children aged 2-12 years, comprising 12.5 mg (developed by DNDi and partners) and 100 mg tablets
- Result of a partnership between DNDi, Chemo Research, Exeltis USA, and Mundo Sano Foundation
- With approval, the FDA granted Chemo Research a neglected tropical disease priority review voucher (PRV)
- 50% of PRV proceeds to be used to enhance access to Chagas treatment
Registered in Argentina in 2018
- Granted registration by Argentina’s National Health Surveillance Agency (ANMAT)
- Result of a collaboration agreement signed in November 2013 between Mundo Sano Foundation and DNDi, in partnership with Laboratorio ELEA PHOENIX (producers of Abarax®)
- The partnership aims to enable broader registration in disease-endemic countries, with a commitment to wider availability of the paediatric dosage form
‘I found out I had Chagas and after that, I got pregnant. The test was positive for my baby too. We started his treatment right away, despite our fears. Today we found out that he is cured!’
