from Jules: purpose of LATTE-2 was to Establish proof of principle for the first ever LA [long-acting] HIV treatment regimen, evaluate the safety and efficacy of CAB LA + RPV LA as maintenance therapy, and select a dosing schedule of CAB LA + RPV LA for progression into phase III studies they also looked at long-acting pharmacokinetics for the regimen and safety and tolerability for injection dosing, initial efficacy for the oral form of CAB+RPV was established in LATTE-1 through 96 weeks. This was an induction/maintenance study - meaning initially 309 patients received for 20 weeks the oral form (pills) of Cabotegravir+abacavir/FTC once daily in order to achieve virology suppression, then for the final 4 weeks of the induction period rilpivirine 25 mg once daily was added. Patients with undetectable, <50 copies/ml viral load were permitted to enter the maintenance phase of this study where they were randomized to 1 of 3 study treatment arms. Patients could receive intramuscular injections every 4 weeks or 8 weeks or continue taking the oral form. At the end of the induction phase 95% of these treatment-naive patients had undetectable viral load. The primary endpoint of the study was the percent of patients with undetectable viral load at week 32: 95% on every 8 week injection dosing and 94% on every 4 weeks IM injection dosing had <50 c/ml, undetectable viral load, while 91% who continued on the oral dosing had undetectable viral load.
