简要总结
Background:
The human body uses antibodies as one way to help fight infection. VRC01LS and VRC07-523LS are antibodies directed against the HIV virus. Researchers want to see if they are safe and well tolerated. In Part A of the study, the researchers studied VRC01LS. Part A of the study was completed in 2017. In Part B, the researchers studied VRC07-523LS. Depending on which antibody received, researchers studied the amount of VRC01LS or VRC07-523LS in the body and how it changes over time. They evaluated the effect of antibodies on CD4+ (Cluster of Differentiation 4) lymphocyte count and HIV viral load, and checked to see if people who get VRC01LS or VRC07-523LS develop an immune response to it.
Objective:
To see if VRC01LS and VRC07-523LS are safe and well tolerated.
Eligibility:
Adults ages 18-70 who are HIV infected but otherwise healthy.
Design:
Participants received the study drug one time by IV infusion. A needle guided a thin tube into a vein. The study drug mixed with salt water was dripped into the vein over about 30 minutes.
Participants were monitored for 30 minutes after the infusion.
Blood samples were taken at the following times:
- Once before the infusion
- 5 times in the 4 hours after the infusion
- 1 time 24 hours after infusion. Some participants may have had 3 optional blood draws in the time period between 4 and 24 hours.
For 3 days after the infusion, participants recorded their temperature and reactogenicity symptoms in a diary.
There were a total of 23 study visits over 48 weeks. Ten visits were in the first 4 weeks. At all visits, participants answered health questions and gave blood samples.
详细描述
Study Design:
Open-label, single dose study to examine safety, tolerability, pharmacokinetics and virologic impact of VRC01LS or VRC07-523LS in HIV-infected viremic adults.
Study Hypotheses:
This is the first study of VRC01LS or VRC07-523LS in HIV-infected viremic adults. The primary hypothesis is that both VRC01LS and VRC07-523LS will be safe for intravenous administration to HIV-1-infected adults. The secondary hypothesis is that VRC01LS and VRC07-523LS will be detectable in human sera with a definable half-life.

结局指标
主要结局
Number of Participants Reporting Local Reactogenicity Signs and Symptoms for 3 Days After VRC01LS or VRC07-523LS Administration
时间窗: 3 days after study product administration
Participants recorded the occurrence of solicited symptoms on a diary card for 3 days after the 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, Version 2.0 \[November 2014\].
Number of Participants With Serious Adverse Events (SAEs)
时间窗: Through 48 weeks after study product administration
SAEs were recorded from receipt of the study product administration through the last expected study visit at Week 48. The relationship between a SAE and the study product was assessed by the investigator on the basis of his or her 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
时间窗: Through 48 weeks after study product administration
Any abnormal laboratory results recorded as unsolicited AEs are summarized. Labs included hematology (hemoglobin, hematocrit, mean corpuscular volume (MCV), platelets, white blood cell (WBC) and red blood cell (RBC) counts, and neutrophil, lymphocyte, monocyte, eosinophil and basophil percents and counts) and chemistry (alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and creatinine). Complete blood count (CBC) and platelet results were collected at screening, Day 0 prior to study product administration (baseline), and Days 2 and 7, Weeks 2-8, 12, 16, 20, 24, 36 and 48 after product administration. Creatinine, ALT, AST and ALP results were collected at screening, baseline, and Days 2 and 7, Weeks 2, 4, 12, 24, 36 and 48 after product administration. Institutional laboratory normal ranges as well as the DAIDS Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 2.0 \[November 2014\] were used.
Number of Participants Reporting Systemic Reactogenicity Signs and Symptoms for 3 Days After VRC01LS or VRC07-523LS Administration
时间窗: 3 days after study product administration
Participants recorded the occurrence of solicited symptoms on a diary card for 3 days after the 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 Systemic Symptom" is the number of participants reporting any systemic 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, Version 2.0 \[November 2014\].
Number of Participants With One or More Unsolicited Non-Serious Adverse Events (AEs)
时间窗: Through 56 days after study product administration
Unsolicited AEs and attribution assessments were recorded in the study database from receipt of the study product administration through the visit scheduled for 56 days (or 8 weeks) after study product administration. At other time periods greater than 56 days (or 8 weeks) after the study product administration, only serious AEs (SAEs reported as a separate outcome and in the AE module), and new chronic medical conditions that required ongoing medical management were recorded through the last study visit. The relationship between an 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.
