US FDA removes need for oral lead-in with long-acting cabotegravir/rilpivirine injections: indication expanded to adolescents
Simon Collins, HIV i-Base
On 24 March 2022, the US FDA announced that the need to use one month on oral formulations of cabotegravir and rilpivirine, before using the long-acting injectable formulations, is now optional. 
Until now, the oral lead-in has been a safety requirement to reduce the risk of a hypersensitivity reaction or other side effects from drugs that have an extremely long half-life and that are not otherwise removeable.
Oral formulations will still be available for people who want to use this additional safety option.
A few days later, the US FDA also extended the indication from adults to also include adolescents who are 12 years or older and weighing at least 35 kg. 
For more details please refer to the full prescribing information.
