GlaxoSmithKline Plc and Novartis AG will contribute research funds to an almost $4 billion global effort to combat malaria as drug-resistant strains of the disease threaten to undo years of progress.

The commitments are part of a wide-ranging initiative, led by a pledge of $1 billion from the Bill & Melinda Gates Foundation, to quell the insect-borne disease that kills hundreds of thousands of people around the world each year.
