Malaria Drug Accelerator (MalDA)

The Malaria Drug Accelerator (MalDA) is a collaboration of 15 scientific laboratories funded by the Bill and Melinda Gates foundation to advance the development of new antimalarial drugs.

Who are we?

The MALDA Consortium is an innovative target-guided discovery platform linking phenotypic hits to function for malaria. MALDA offers a new research paradigm that compliments the existing ways malaria drugs are discovered: A virtual pharmaceutical company.

How do we work together?

The MALDA Consortium is a collaboration between fifteen international groups, funded by BMGF.
