ViiV resubmits cabotegravir plus rilpivirine long-acting injections (Cabenuva) to FDA for approval

Simon Collins, HIV i-Base

On 29 July 2020, a press statement from GSK included information that the long-acting formulation of cabotegravir plus rilpivirine injections (CAB/RPV-LA) have been resubmitted to the US FDA. A decision on approval is expected in early 2021. [1]

The application for the first injectable HIV combination was expected to be decided last December, but outstanding questions relating to manufacturing delayed this decision. [2, 3]

The application includes safety and efficacy data from the phase 3 ATLAS and FLAIR studies that have already reported. This is for monthly injections, rather than two-monthly injections used in the ATLAS-2M study and reported at CROI 2020. [4]

Cabotegravir is an integrase inhibitor developed by ViiV Healthcare and rilpivirine is an NNRTI developed by Janssen Sciences. Development of CAB/RPV long-acting combination is led by ViiV Healthcare with the trade name Cabenuva.

comment

It is good that a regulatory decision is closer given the high expectation among HIV positive people for an alternative to daily tablets. Access though in many countries will be dependent on price.

Although CAB/RPV-LA was approved in Canada in March 2020, it is not expected to be available through the public health system until September, when a price will also hopefully be announced. [5]

Several studies at AIDS 2020 also reported on the challenges for health systems in different settings to adapt to this new way of delivering ART and on results from a small expanded access programme. [6, 7, 8, 9]

The same press release also reported that development of the entry inhibitor combinectin in early stage development (GSK ‘934) has been ended due to “portfolio prioritisation”. [1]

This report was first posted on 6 August 2020.
