Official title
VRC 609: A Phase I, Open-Label, Dose-Escalation Study of the Safety and Pharmacokinetics of a Human Monoclonal Antibody, VRC-HIVMAB091-00-AB (N6LS), Administered Intravenously or Subcutaneously With or Without Recombinant Human Hyaluronidase PH20 (rHuPH20) to Healthy Adults
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: The experimental product in this study, N6LS, is a human monoclonal antibody. Antibodies are one way that the human body fights infection. Monoclonal means that all the antibodies in the product are the same. N6LS is directed against the HIV virus. There is no HIV in the N6LS study product and you cannot get HIV from this product. This study is the first time N6LS is tested in humans. It was given into a vein in the arm (intravenously, IV) or as an injection underneath the skin (subcutaneously, SC). The study also tested N6LS mixed with an enzyme, rHuPH20 (recombinant human hyaluronidase). rHuPH20 increases the spread of fluids injected underneath your skin (subcutaneously, SC) and allows for the rapid delivery of large volume injections that can be given with a single needle. It was given as a SC infusion using a small needle attached to an infusion pump. Study products were only given to healthy adults who are not infected with HIV. Objective: The main purpose of the study is to see if N6LS alone and N6LS mixed with rHuPH20 is safe in healthy adults. Another goal is to learn how amounts of N6LS in the body change over time. Study Plan: Assigned study groups depended on the dose of product, the numbers of times the product was given (once or three times at 12-week intervals), and how the product was given (IV or SC). Blood samples for research were collected at most of the visits. There were about 14 clinic visits over 6 months for all groups who got one dose of product, and about 26 clinic visits over 12 months for the groups who got three doses of product.
