Merck Licenses Experimental HIV Pill to Generic Makers in 129 Countries
The agreements include seven generic makers and cover countries that account for most new HIV diagnoses worldwide, Merck said.
On Friday, Merck announced seven royalty-free licensing agreements with generic drug manufacturers to produce and sell its experimental once-monthly oral HIV pill, alimatravir, across 129 low- and lower-middle-income countries.
With an estimated 40.9 million people living with HIV globally in 2025, the investigational drug MK-8527 aims to provide one month of protection from a single dose, simplifying adherence for affected populations.
The agreements include three manufacturers in sub-Saharan Africa and four in India. Gregg Szabo, head of Merck's global vaccines and infectious diseases unit, said "This is the first time that sub-Saharan African manufacturers have been included in licenses from the very beginning."
Although trial results are not expected until the second half of next year, Merck is investing early in manufacturing capacity, enabling generic licensees to begin scaling production immediately.
This strategy mirrors a 2024 move by Gilead Sciences, which granted royalty-free licenses to six manufacturers for its HIV prevention medicine in 120 countries, following World Health Organization calls to improve access.
