Summary
Antiretrovirals can interfere with manufacture of lentiviral vector-based gene therapies by inhibiting transduction of harvested stem cells. Efavirenz taken around mobilization and apheresis could compromise the product.
What this interaction means in plain words
Efavirenz and Elivaldogene autotemcel 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
Antiretroviral drugs inhibit lentiviral vector transduction during ex vivo manufacturing.
What to do
Stop efavirenz at least one month before mobilization, allow time for drug elimination, and keep it stopped until all apheresis cycles are completed. Arrange an alternative HIV management plan with the specialist team.
