Background: HIV is a serious disease with no cure or vaccine to prevent it. Using antibodies could be a way to prevent HIV infection. Antibodies are made by the human body to fight germs. Researchers want to test an antibody, CAP256V2LS. Objective: To test CAP256V2LS to see if it is safe and how the body responds to it. Eligibility: Healthy people, ages 18-60 Design: Participants were screened with a medical history, physical exam, and blood tests. Some females had a pregnancy test. Participants were assigned to one of two groups. Based on their group, they got 1 dose of CAP256V2LS in 1 of 2 ways: - Some participants got CAP256V2LS as an infusion. A thin tube was placed in an arm vein and CAP256V2LS was given into the vein using a pump. - Some participants got CAP256V2LS injected under the skin. A small needle was used to inject CAP256V2LS into the fatty tissue of the belly, arm, or thigh. They got 1 to 4 injections. On the day they got CAP256V2LS, participants gave blood samples at different time points. Participants were asked to check their temperature every day for 7 days after receiving CAP256V2LS. They used a tool to measure any redness, swelling, or bruising they may have at the site where they received the study drug. Participants had visits at least 2-3 times during the first week after they got CAP256V2LS. Then they had about 9 more visits over the next 6 months. Visits included blood tests.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Number of Participants Reporting Local Reactogenicity Signs and Symptoms Within 7 Days of CAP256V2LS Product Administration | Participants recorded the occurrence of solicited symptoms on a diary card for 7 days after 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. | 7 days after CAP256V2LS product administration, at approximately Week 1 | |
Primary | Number of Participants Reporting Systemic Reactogenicity Signs and Symptoms Within 7 Days of CAP256V2LS Product Administration | Participants recorded the occurrence of solicited symptoms on a diary card for 7 days after 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, Corrected Version 2.1. | 7 days after CAP256V2LS product administration, at approximately Week 1 | |
Primary | Number of Participants With One or More Unsolicited Non-Serious Adverse Events (AEs) Following CAP256V2LS Product Administration | Unsolicited adverse event (AE) data collection included AEs of all severities from the date of product administration through the Day 28 post-product administration visit. At other time periods greater than 4 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 (reported as a separate outcome) 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. | Day 0 through 4 weeks after CAP256V2LS Product Administration | |
Primary | Number of Participants With Serious Adverse Events (SAEs) Following CAP256V2LS Product Administration | SAEs were recorded from receipt of study product administration through the last expected study visit at Week 24. 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. | Day 0 after CAP256V2LS product administration through the study participation, up to Week 24 | |
Primary | Number of Participants With New Chronic Medical Conditions Following CAP256V2LS Product Administration | 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. 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. | Day 0 after CAP256V2LS product administration through the study participation, up to Week 24 | |
Primary | Number of Participants With Abnormal Laboratory Measures of Safety Following CAP256V2LS Product Administration | Abnormal laboratory results recorded as unsolicited adverse events (AEs) are summarized. Safety lab parameters included hematology (hemoglobin, hematocrit, mean corpuscular volume (MCV) platelets, and white blood cell (WBC), red blood cell (RBC), neutrophil, lymphocyte, monocyte, eosinophil and basophil counts) and chemistry (alanine aminotransferase (ALT) and creatinine). Complete Blood Count (CBC) with differential and Chemistry (ALT and creatinine) results were collected at different timepoints throughout the study per the protocol's schedule of evaluations. Comprehensive metabolic panel (CMP) was collected at baseline, and 2 weeks after product administration and as needed at additional timepoints. 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. | Day 0 through 4 weeks after CAP256V2LS Product Administration | |
Secondary | Pharmacokinetic (PK) Parameters of CAP256V2LS: Maximum Observed Serum Concentration (Cmax) | Cmax is the peak serum concentration that CAP256V2LS achieves after it has been administered; it is determined as a maximum value on the summary pharmacokinetic (PK) curve for each study group. | Baseline through 24 weeks after CAP256V2LS product administration | |
Secondary | Pharmacokinetic (PK) Parameters of CAP256V2LS: Time to Reach Maximum Observed Serum Concentration (Tmax) | Tmax is the time it takes to reach Cmax of CAP256V2LS after it has been administered; it is determined based on the summary PK curve for each dose group. | Baseline through 24 weeks after CAP256V2LS product administration | |
Secondary | Pharmacokinetic (PK) Parameters of CAP256V2LS: Beta Half-life (T1/2b) | Beta half-life (T1/2b) is the time required for half of the CAP256V2LS product to be eliminated from the serum. | Baseline through 24 weeks after CAP256V2LS product administration | |
Secondary | Pharmacokinetic (PK) Parameters of CAP256V2LS: Clearance Rate | Clearance is the rate of CAP256V2LS elimination divided by the plasma CAP256V2LS concentration; determined based on the summary pharmacokinetic (PK) curve for each study group. Clearance following a SC administration is calculated as Clearance (CL)/Bioavailability (F). | Baseline through 24 weeks after CAP256V2LS product administration | |
Secondary | Pharmacokinetic (PK) Parameters of CAP256V2LS: Volume of Distribution | Theoretical volume that would be necessary to contain the total amount of administered drug at the same concentration as observed in plasma. It represents the degree to which a drug is distributed in body tissue rather than the plasma and calculated based in the PK curve for each study group. Volume of distribution following a SC administration is calculated as Volume of distribution (V)/Bioavailability (F). | Baseline through 24 weeks after CAP256V2LS product administration |
