Summary
Antiretrovirals such as lamivudine can interfere with manufacturing of the gene-modified cells because they inhibit lentiviral vector transduction. This may result in an inadequate or unusable product.
What this interaction means in plain words
Betibeglogene autotemcel and Lamivudine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Nucleoside reverse transcriptase inhibitors block reverse transcription of the lentiviral vector, impairing transduction of harvested cells.
What to do
Stop lamivudine at least one month before mobilization, or longer for drug elimination, and until all apheresis cycles are finished. Involve an HIV specialist in the plan.
