Unlike other forms of malaria, Plasmodium vivax can persist silently in the liver as dormant forms called hypnozoites.
These dormant parasites may reactivate weeks or months later, causing relapse even after the bloodstream infection has been cleared.
This means a patient may appear cured — but still carry hidden liver-stage infection capable of restarting disease.
Dormant liver-stage malaria is not a one-time illness. Repeated relapse can cause:
Without eliminating dormant liver parasites, malaria returns.
80M+ Patients Cannot Access Radical Cure
As a result, a large proportion of patients remain untreated for dormant liver-stage malaria despite available medicines.
When dormant malaria is left untreated:
Eliminating malaria requires stopping relapse at its source – in the liver.
Such an approach could:
AliquantumRx is developing CALM (Cethromycin Against Liver-Stage Malaria), a program designed to eliminate dormant liver-stage malaria without the need for G6PD testing.
CALM is focused on creating a safer, scalable path toward relapse prevention and broader access to radical cure.
