Novartis and Medicines for Malaria Venture launch patient trial in Africa for KAF156, a novel compound against multidrug-resistant malaria
- Compound has potential to be a game-changer in malaria elimination, rapidly clearing malaria infection, including resistant strains, and blocking parasite transmission
- KAF156 is first compound from the imidazolopiperazines, a novel class of antimalarials, to enter phase IIb combination studies
- Clinical trial has started early August in adults with malaria and is planned to expand to adolescents and children in a total of nine countries in Africa and Asia
Novartis and Medicines for Malaria Venture (MMV) have launched a patient trial for KAF156, a next-generation antimalarial compound with the potential to treat drug-resistant strains of the malaria parasite. The trial will test the efficacy of KAF156 in combination with a new, improved formulation of the existing antimalarial lumefantrine. The first trial center is operational in Mali and will be followed by sixteen additional centers across a total of nine countries in Africa and Asia over the next few months.
"This new milestone underscores our company's long-standing commitment to the fight against malaria," said Vas Narasimhan, Global Head of Drug Development and Chief Medical Officer, Novartis. "With nearly half of the world's population at risk, malaria continues to be a major public health challenge. Developing new antimalarial medicines is critical to achieving malaria elimination. Innovative science continues to be our best weapon against the disease."
KAF156 belongs to a novel class of antimalarial compounds called imidazolopiperazines. It has the potential to clear malaria infection, including resistant strains, as well as to block the transmission of the malaria parasite. As demonstrated in a phase IIa proof-of-concept trial, the compound is fast-acting and potent across multiple stages of the parasite's lifecycle, rapidly clearing both P. falciparum and P. vivaxparasites.
Next-generation antimalarials are urgently needed to tackle rising parasite resistance to current therapies. Emergence of resistance to both artemisinin and many partner drugs has been reported in Asia  and reduced sensitivity to artemisinin has also been sporadically reported in Africa .
The phase IIb study will test multiple dosing combinations and dosing schedules of KAF156 and lumefantrine, including the feasibility of a single dose therapy in adults, adolescents and children. As children are the most vulnerable to malaria, the goal is to include them in the clinical trial as quickly as possible, following safety review of the data generated in adults, thereby potentially accelerating the development of a pediatric formulation.
"To build on the gains made against malaria since the turn of the century, we need new medicines that are effective across all types of resistance patterns and geographies, and that are easy to administer, especially to children," said Dr David Reddy, CEO of MMV. "With the phase IIb trial of KAF156-lumefantrine now underway, the MMV-Novartis partnership is drawing closer to the exciting prospect of such a new medicine that would be a powerful tool to fight the disease."
It is important to test new drug candidates in the settings where they will be used. Conducted in state-of-the-art centers across Africa and Asia, the KAF156 trial is particularly complex given that multiple dosing combinations and dosing schedules are being tested in parallel in three different age groups.
"Malaria is a major public health concern in Mali - especially for children. Thus, the need for novel antimalarials is urgent," said Dr. Bakary Fofana, clinical trial investigator at the Malaria Research and Training Center in Bougoula - Hameau. "Because it is a new compound with the potential to treat malaria including strains resistant to currently used antimalarials, we are particularly motivated to run the KAF156 patient trial at our site in Mali."
KAF156 is the result of a Wellcome Trust, MMV and Singapore Economic Development Board supported joint research program with the Novartis Institute for Tropical Diseases, the Genomics Institute of the Novartis Research Foundation, and the Swiss Tropical and Public Health Institute.
Novartis is developing KAF156 with scientific and financial support from MMV (in collaboration with the Bill & Melinda Gates Foundation).
The partnership between MMV and Novartis builds on a long-standing successful collaboration in antimalarial drug development, which led to the launch in 2009 of the first high-quality artemisinin combination therapy for children. Since 2001, Novartis has delivered more than 300 million dispersible pediatric treatments without profit to malaria-endemic countries.
About the Novartis Malaria Initiative
The Novartis Malaria Initiative drives research, development and access to novel treatments to eliminate malaria. It is one of the pharmaceutical industry's largest access-to-medicine programs. Since 2001, the initiative has delivered more than 800 million treatments without profit, mostly to the public sector of malaria-endemic countries.
The Novartis Malaria Initiative is integrated in Novartis Social Business, a unit which includes Novartis Access, SMS for Life and the Novartis Healthy Family programs.
