Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study
A Phase 3b, single arm, open-label, multicenter study to evaluate the safety and to demonstrate the non-inferiority of the sustained virologic response 12 weeks post dosing (SVR12) rates of 8 weeks of treatment with the glecaprevir (GLE)/pibrentasvir (PIB) combination regimen to the historical SVR12 rate of 12 weeks of treatment with the GLE/PIB in treatment-naïve adults with chronic HCV GT 1, 2, 4, 5, or 6 infection and compensated cirrhosis.
