简要总结
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.
详细描述
Study Design:
This is the first study in healthy adults of the N6LS monoclonal antibody (MAb). It was a dose-escalation study to examine safety, tolerability, dose, and pharmacokinetics (PK) of N6LS administered intravenously (IV) and subcutaneously (SC) to healthy adults. For SC administration, N6LS was administered alone or co-administered with the permeation enhancer rHuPH20 enzyme. Primary hypotheses are that N6LS administration to healthy adults will be safe by the IV and SC routes, alone and with rHuPH20 co-administration. A secondary hypothesis is that all N6LS administrations will be detectable in human sera with a definable half-life
Product Description:
N6LS (VRC-HIVMAB091-00-AB) is a human MAb targeted to the HIV-1 CD4 binding site. It was developed by the VRC/NIAID/NIH and manufactured under current Good Manufacturing Practice (cGMP) regulations at the VRC Vaccine Pilot Plant operated under contract by the Vaccine Clinical Materials Program (VCMP), Leidos Biomedical Research, Inc., Frederick, MD. The product was provided as a sterile aqueous buffered solution in 10 mL glass vials at a concentration of 100 mg/mL and volume of 6.25 mL.
Each vial of ENHANZE™ Drug Product (EDP) contains 0.5 mL of rHuPH20 formulated at a concentration of 1 mg/mL (approximately 110,000 U/mL rHuPH20). rHuPH20 is a tissue permeability modifier that depolymerizes hyaluronan (HA), increasing the dispersion of a substance into the subcutaneous space, which enables SC delivery of co-administered antibody (-ies) at higher dose volumes (e.g., >10 mL) that cannot be administered quickly without rHuPH20. EDP is manufactured by Ajinomoto Althea, Inc. (San Diego, CA) for Halozyme Therapeutics, Inc. (San Diego, CA) and is supplied in 2 mL glass vials as a sterile, single-dose, injectable liquid.

主要结局
Number of Participants With New Chronic Medical Conditions Following N6LS Product Administration Alone or N6LS Co-Administered With rHuPH20
时间窗: Day 0 after product administration through the study participation, up to Week 24 for single dose groups and up to Week 48 for repeat dose groups
New chronic medical conditions that required ongoing medical management were recorded from receipt of first study product administration through the last expected study visit at Week 24 for single dose groups and at Week 48 for repeat dose groups. The relationship between a new chronic medical condition and the study product was assessed by the investigator based on clinical judgment and the definitions outlined in the protocol. A participant with multiple experiences of the same event is counted once using the event of worst severity.
Number of Participants With Abnormal Laboratory Measures of Safety Following N6LS Product Administration Alone or N6LS Co-Administered With rHuPH20
时间窗: Day 0 through 8 weeks after each product administration, at approximately Week 8 for all dose groups, and at Weeks 20 and 32 for repeat dose groups
Abnormal laboratory results recorded as unsolicited adverse events (AEs) are summarized. Safety lab parameters included hematology (hemoglobin, hematocrit, mean corpuscular volume (MCV) platelets, and neutrophil, lymphocyte, monocyte, eosinophil and basophil counts) and chemistry (alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, alkaline phosphatase (ALP) and Comprehensive Metabolic Panel (CMP)). Complete Blood Count (CBC) with differential and chemistry (ALT, AST, ALP, creatinine and CMP) results were collected at different timepoints throughout the study per the protocol's schedule of evaluations. Institutional laboratory normal ranges as well as the DAIDS Table for Grading the Severity of Adult and Pediatric Adverse Events, Corrected Version 2.1 were used.
Number of Participants Reporting Local Reactogenicity Signs and Symptoms Within 3 Days of N6LS Product Administration Alone or N6LS Co-Administered With rHuPH20
时间窗: 3 days after each product administration, at approximately Day 3 for all dose groups, and at approximately Day 87 and Day 171 for repeat dose groups
Participants recorded the occurrence of solicited symptoms on a diary card for 3 days after each study product administration and reviewed the diary card with clinic staff at a follow up visit. Participants were counted once for each symptom at the worst severity if they indicated experiencing the symptom more than one time at any severity during the reporting period. The number reported for "Any Local Symptom" is the number of participants reporting any local symptom at the worst severity. Reactogenicity grading (Mild, Moderate, Severe) was done using the U.S. Department of Health and Human Services, National Institutes of Health, National Institute of Allergy and Infectious Diseases, Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Corrected Version 2.1.
Number of Participants With One or More Unsolicited Non-Serious Adverse Events (AEs) Following N6LS Product Administration Alone or N6LS Co-Administered With rHuPH20
时间窗: Day 0 through 8 weeks after each product administration, at approximately Week 8 for all dose groups, and at Weeks 20 and 32 for repeat dose groups
Unsolicited adverse event (AE) data collection included AEs of all severities from the date of product administration through the Day 56 (8 weeks) after each product administration visit. After the Day 56 (8 weeks) after each product administration visit, only serious AEs (SAEs reported as a separate outcome and in the AE module) and new chronic medical conditions that require ongoing medical management (reported as a separate outcome) were recorded through the last study visit. The relationship between a non-serious AE and the study product was assessed by the investigator based on clinical judgment and the definitions outlined in the protocol. A participant with multiple experiences of the same event is counted once using the event of worst severity.
Number of Participants With Serious Adverse Events (SAEs) Following N6LS Product Administration Alone or N6LS Co-Administered With rHuPH20
时间窗: Day 0 after product administration through the study participation, up to Week 24 for single dose groups and up to Week 48 for repeat dose groups
SAEs were recorded from receipt of first study product administration through the last expected study visit at Week 24 for single dose groups and at Week 48 for repeat dose groups. The relationship between a SAE and the study product was assessed by the investigator based on clinical judgment and the definitions outlined in the protocol. A participant with multiple experiences of the same event is counted once using the event of worst severity.
Number of Participants Reporting Systemic Reactogenicity Signs and Symptoms Within 3 Days of N6LS Product Administration Alone or N6LS Co-Administered With rHuPH20
时间窗: 3 days after each product administration, at approximately Day 3 for all dose groups, and at approximately Day 87 and Day 171 for repeat dose groups
