First malaria medicine for young infants 2-5 kg receives approval

09 Jul 2025
  • Coartem® (artemether-lumefantrine) Baby becomes first malaria treatment approved for newborn babies and young infants
  • Rapid approvals in eight African countries now expected under special global health scheme run by Swiss agency for therapeutic products (Swissmedic)
  • Novartis plans to introduce infant-friendly Coartem Baby on largely not-for-profit basis to increase access in areas where malaria is endemic

Geneva, 08 July 2025 – Coartem® (artemether-lumefantrine) Baby has been approved by Swissmedic as the first malaria medicine for newborns and young infants. The new treatment, also known as Riamet® Baby in some countries, was developed through an MMV and Novartis collaboration to treat the potentially deadly mosquito-borne disease.

Eight African countries also participated in the assessment and are now expected to issue rapid approvals under the Swiss agency’s Marketing Authorization for Global Health Products procedure.1 Novartis plans to introduce the infant-friendly treatment on a largely not-for-profit basis to increase access in areas where malaria is endemic.

“Malaria is one of the world’s deadliest diseases, particularly among children. But with the right resources and focus, it can be eliminated,” said Martin Fitchet, CEO of MMV. “The approval of Coartem Baby provides a necessary medicine with an optimized dose to treat an otherwise neglected group of patients and offers a valuable addition to the antimalarial toolbox.” 

Until now, there has been no approved malaria treatment for infants weighing less than 4.5 kilograms, leaving a treatment gap. They have instead been treated with formulations intended for use in older children, which may increase the risk of overdose and toxicity. Malaria vaccines are also not approved for the youngest babies.2

Some 30 million babies are born in areas of malaria risk in Africa every year,3 with one large survey across West Africa reporting infections ranging between 3.4% and 18.4% in infants younger than 6 months old.4 However,current data on malaria in young babies is extremely limited, as they are rarely included in clinical trials of antimalarial agents.5,6

“The available malaria treatments have only been properly tested in children aged at least 6 months because smaller infants are usually excluded from treatment trials,” said Professor Umberto D'Alessandro, Director of the MRC Unit, The Gambia at the London School of Hygiene and Tropical Medicine. “That matters because neonates and young infants have immature liver function and metabolize some medicines differently, so the dose for older children may not be appropriate for small babies.”

The new dose strength designed for young infants was developed by Novartis with the scientific and financial support of MMV, and as part of the PAMAfrica consortium, which is co-funded by the European & Developing Countries Clinical Trials Partnership and the Swedish International Development Cooperation Agency. The treatment is dissolvable, including in breast milk, and has a sweet cherry flavor to make it easier to administer. 

“For more than three decades, we have stayed the course in the fight against malaria, working relentlessly to deliver scientific breakthroughs where they are needed most,” said Vas Narasimhan, CEO of Novartis. “Together with our partners, we are proud to have gone further to develop the first clinically proven malaria treatment for newborns and young babies, ensuring even the smallest and most vulnerable can finally receive the care they deserve.”

About the CALINA study

The Swissmedic approval is based on the Phase II/III CALINA study, which investigated a new ratio and dose of Coartem (artemether-lumefantrine) to account for metabolic differences in babies under 5 kilograms. It is indicated for the treatment of infants and neonates weighing between 2 and less than 5 kilograms with acute, uncomplicated infections due to Plasmodium falciparum or mixed infections, including P. falciparum. Coartem is known by the brand name Riamet in Switzerland and some other countries.

About malaria

Malaria is a life-threatening disease caused by a parasite and spread to humans by certain types of mosquitoes. According to the most recent WHO data, there were 263 million cases of malaria and 597,000 deaths in 2023, almost all of them in Africa. Children under 5 years old accounted for about three in four malaria deaths in the region.7
