TRIUMPH is a prospective, non-interventional observational study on the use of the fixdose combination TRIUMEQ (Dolutegravir/Abacavir/Lamivudine) and the respective monitoring measures in the practice of HIV care in Germany. The primary study objective is a descriptive report of the incidence of therapeutic monitoring measures in HIV-infected patients under TRIUMEQ therapy in everyday routine practice in Germany. The study is designed to enroll approximately 400 patients. There are no protocol-mandated visits or procedures associated with the study. Each patient is expected to participate for a maximum of 3 years or until premature discontinuation (i.e., discontinuation of TRIUMEQ, due to death, withdrawal of consent, lost to follow-up. TRIUMEQ is a registered trademark of the ViiV Healthcare group of companies.

Inclusion Criteria:

• Documented HIV infection
• Age ≥ 18 years
• HLA-B*5701-negative
• Decision for first initiation of TRIUMEQ therapy made by the attending physician independent of the inclusion in this observational study

Exclusion Criteria:

• Prior dolutegravir therapy (cf. also Capping ABC in section 3.3 Recruitment)
• Participation in a clinical trial during this study

Approx. 40 HIV treatment sites in Germany are planned to be involved in the documentation. The recruitment target is to include a total of 400 patients in the study across Germany. In order to allow for adequately answering in particular the problems regarding HLA-B*5701 testing, at least half of the recruited population should not have received abacavir (ABC) in their prior therapy. Each site will be allowed to recruit a maximum of 5 patients per month and a maximum of 20 patients in total. If the monthly quota of 5 patients is not utilized, the difference may be transferred to the subsequent months.
