Simon Collins, HIV i-Base

On 29 April 2019, ViiV Healthcare announced that the long-acting two-drug injection formulation of cabotegravir/rilpivirine has been submitted to the US FDA. [1]

This announcement was expected following the presentation at CROI 2019 last month of the primary endpoint results from the phase 3 FLAIR and ATLAS studies. [2]

These studies reported >90% viral suppression <50 copies/mL at week-48 meeting criteria for non-inferiority compared to three-drug oral therapy.

The press release also notes that submission to the European Medicines Agency (EMA) is expected within the next few months.
