General
The safety of this drug in patients with no antiretroviral treatment history was assessed in 2 phase 3 trials; patients received doravirine either as a single component in combination with other antiretroviral drugs as background regimens or as a component of this combination drug. Most (66%) side effects associated with this combination drug were of mild severity (grade 1).
The safety of this combination drug in virologically-suppressed patients was assessed in a trial where virologically-suppressed patients were switched from a baseline regimen to this combination drug; overall, the safety profile in virologically-suppressed patients was similar to the safety profile in patients with no antiretroviral treatment history.
Unless otherwise specified, the side effects provided below were reported during the trial using this combination drug.[Ref]
