Researchers have developed a new antimalarial drug candidate designed to address the growing challenge of drug resistance and potentially reduce malaria transmission.
The first-in-class clinical candidate, MK-7602, has been developed through a longstanding collaboration between WEHI and global biopharmaceutical company MSD (tradename of Merck & Co., Inc., Rahway, N.J., USA).
Pre-clinical research now published in eBiomedicine, a Lancet journal, shows the novel drug candidate targets the malaria parasite at multiple stages of its life cycle, with potential applications for both treating infections and reducing disease spread.
Since the completion of this preclinical research, results from early stage clinical trials continue to provide evidence for the potential of MK-7602 for the treatment of malaria.
At a glance
• First-in-class antimalarial drug candidate MK-7602 shows potent activity against both Plasmodium falciparum and Plasmodium vivax, the two most common malaria parasites affecting humans.
• Evidence suggests the compound's dual-action mechanism, targeting two essential parasite enzymes, may help combat the development of drug resistance.
• The drug candidate has been developed through a longstanding collaboration between WEHI and MSD, with pre-clinical studies indicating a promising safety profile and pharmacokinetic properties.
Working to advance the fight against malaria
The emergence of drug-resistant parasites has complicated efforts to control and eliminate malaria, which remains a leading cause of preventable illness and death globally, killing an estimated 600,000 people a year.
Children under 5 are the most vulnerable – it is estimated that a child dies of malaria every minute.
The new drug candidate MK-7602 targets the most prevalent malaria parasites in humans, Plasmodium falciparum and Plasmodium vivax, and blocks two essential parasite enzymes, providing a unique dual-action strategy with the potential to reduce the risk of resistance.
Professor Alan Cowman AC, lead investigator from WEHI, said new and better treatments for malaria were urgently needed, to drive forward global efforts towards eradication.
“The evaluation of MK-7602 represents an important step in our fight against malaria,” he said.
“Its ability to target multiple stages of the parasite life cycle, combined with its high barrier to resistance, supports our ongoing efforts to find new ways to combat this devastating disease for patients who need the hope of new treatments.”
