TRIAL DESCRIPTION
Public title CAPRISA 012A
Official scientific title A Phase ǀ Study to determine the Safety and Pharmacokinetics of the Human monoclonal Antibodies, VRC07-523LS and PGT121 administered subcutaneously to HIV negative Adults in South Africa
Brief summary describing the background and objectives of the trial The overall goal of the CAPRISA 012 trial is to develop a combination of two anti-HIV mAbs as a new, safe and effective long-acting HIV prevention technology, principally for women. The trial aims to fast-track and efficiently advance passive immunization as an emerging HIV prevention strategy. The CAPRISA 012 trial will be conducted in two parts. The aim of Part A CAPRISA 012A (described in this summary) is to determine the safety and pharmacokinetic (PK) profile of the human mAbs VRC07-523LS and PGT121 administered subcutaneously alone and in combination to HIV negative women in South Africa Component 1 of Part B is a phase I assessment of the safety and PK of CAP256-VRC26.25LS. Based on the phase I data, one or both of the proposed two-antibody combinations will proceed to component 2 of Part B, which is a phase II trial that will assess extended safety and obtain an estimate of efficacy in preventing HIV infection in young women. Part B of the CAPRISA 012 trial will only commence following regulatory approvals. Primary objective • To evaluate the safety of one and two doses of VRC07-523LS and/or PGT121 553 mAbs administered SC. Secondary objectives • To characterize the PK profile of VRC07-523LS mAb administered SC individually as a single dose or as two doses 12 and 24 weeks apart. • To characterize the PK profile of PGT121 mAb administered SC individually as a single dose or as two doses 12 weeks apart. • To characterize the PK profile of VRC07-523LS and PGT121 mAbs administered simultaneously. • To assess the acceptability of VRC07-523LS and PGT121 mAbs SC • To evaluate the concentrations and functional activity of VRC07-523LS and/ or PGT121 mAb in plasma and genital samples following SC administration. • To determine whether SC administration of VRC07-523LS and/or PGT121 mAbs induces anti-mAbs.
