July 24 (Reuters) – Merck said on Friday it signed seven voluntary licensing agreements with generic drug manufacturers to make and sell lower-cost versions of its ​experimental once-monthly oral HIV pill in 129 low- ‌and lower-middle-income countries.

The drug, alimatravir, is currently in late-stage development. Merck said it is investing early in its product manufacturing capacity as trials continue.

Here are some details:

• Merck said the agreements are with three sub-Saharan Africa ‌manufacturers – ​Aspen Pharmacare Holdings, Quality Chemical Industries ⁠and UCL – and four ⁠Indian companies, which are Aurobindo, Cipla, Emcure and Viatris.

• The royalty-free agreements with these companies cover both the public and private sectors and will enable supply of generic alimatravir ​in these 129 countries that account for a substantial majority of new HIV diagnoses globally, the drugmaker said.

• “This is ⁠the first time that sub-Saharan African ⁠manufacturers have been included in licenses from the ​very beginning.” said Gregg Szabo, head of Merck’s global vaccines and ​infectious diseases unit.

• Merck is still enrolling patients to ‌test alimatravir, which is expected to provide one month of protection from HIV-1 starting within one hour after dosing.

• “We’re likely not to have any trial results until the second half ⁠of next year, but this will give time for the generic licensees to start working to scale up their production” said Paul ⁠Schaper, head of ‌global pharmaceutical public policy at Merck.

• In 2024, ⁠Gilead Sciences granted royalty-free licenses to six ​generic drug ‌manufacturers to make and sell cheaper copycat ​versions of ⁠its HIV prevention medicine, lenacapavir, in 120 low and lower-middle income countries.

• The World Health Organization has urged governments and drugmakers to improve access to affordable HIV medicines, including through voluntary licensing and greater generic competition.
