Current or anticipated use of contraindicated medications (see Summary of Product Characteristics (SmPC) for Symtuza® and Biktarvy®) or anticipated systemic chemotherapy during study enrolment (administration of any contraindicated medication must be discontinued at least 30 days prior to the baseline visit and for the duration of the study).
4. Known resistance to the components of study medications (see section 6.1.3 for more details).
