P1101 is a Phase I/II, dose-finding, safety, tolerability, drug-drug interaction and pharmacokinetics study of Raltegravir (RAL) in TB co-infected children (≥ 4 weeks to < 12 years of age) taking Rifampicin (RIF)-based tuberculosis (TB) therapy. The study objectives are to determine the pharmacokinetics and appropriate dose of RAL and to determine safety and tolerance of RAL-containing ART when administered with a RIF-containing anti-TB therapy in HIV/TB co-infected children.
