  • Number of Subjects Experiencing Infusion Reaction During Product Administration [ Time Frame: About 30 minutes of product administration ]
    Possible infusion reaction symptoms: unusually tired/feeling unwell, muscles aches, headache, chills, rigors, nausea, fever, joint pain, urticaria/rash, and pruritus. Also information was collected if administration was slowed down or stopped for reactogenicity reasons.
  • Number of Subjects Reporting Systemic Reactogenicity Signs and Symptoms Within 3 Days of Product Administration [ Time Frame: 3 days after the product administration ]
    Subjects recorded 3-day systemic symptoms in a diary after study product administration. Solicited symptoms occurring during the 3 days after receipt of study product include: unusually tired/feeling unwell, muscles aches, headache, chills, nausea, temperature and joint pain. Subjects recorded highest measured temperature daily. Clinicians reviewed the diary with the subject and collected resolution information for any symptoms that were not resolved within 3 days. Subjects were counted once for each symptom if they experienced the symptom at any severity during the reporting period. The number reported for any systemic symptom is the number reporting one or more systemic symptom at any severity. Solicited reactogenicity recorded without an attribution assessment. Grading was done by Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events Version 2.1.
  • Number of Subjects Reporting Local Reactogenicity Signs and Symptoms Within 7 Days of Product Administration [ Time Frame: 7 days after the product administration ]
    Local symptoms assessed and recorded by the clinicians. Solicited local symptoms include pain/tenderness, swelling, redness, bruising, and pruritus (itchiness) at the product administration site. Clinicians assessed the study product administration site for local symptoms on the day of product administration after completion of the administration and on Days 1, 2 and 7 post administration. Subjects were counted once for each symptom if they experienced the symptom at any severity during the reporting period. If symptoms were experienced, clinicians collected resolution information for any symptoms that were not resolved within 7 days. Solicited reactogenicity recorded without an attribution assessment. If symptoms were reported, grading was done by Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events Version 2.1.
  • Number of Subjects Reporting 1 or More Unsolicited Adverse Events [ Time Frame: Through 24 weeks after product administration ]
    Unsolicited adverse events (AEs) collected during the period from study product administration at Day 0 through 28 days after product administration. Between and after the indicated time period, through the last expected study visit at 24 weeks after product administration, only new chronic medical conditions collected as unsolicited AEs. A subject with multiple experiences of the same event is counted once using the event of highest severity. Grading done by Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events Version 2.1.
  • Number of Subjects Reporting Serious Adverse Events [ Time Frame: Through 24 weeks after product administration ]
    Serious adverse events (SAEs) collected during the period from study product administration at Day 0 through 24 weeks after product administration.Grading done by Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events Version 2.1.

Safety and Pharmacokinetics of a Human Monoclonal Antibody, VRC-EBOMAB092-00-AB (MAb114), Administered Intravenously to Healthy Adults
VRC 608: A Phase I, Open-Label, Dose-Escalation Study of the Safety and Pharmacokinetics of a Human Monoclonal Antibody, VRC-EBOMAB092-00-AB (MAb114), Administered Intravenously to Healthy Adults

Background:

Ebola is a virus that has infected and killed people mostly in West Africa. There is no treatment or prevention for it, but several drugs are being studied. Researchers want to test the drug MAb114 in healthy people not exposed to Ebola to see whether it can be used for Ebola treatment in people who are infected in the future. This trial will not expose volunteers to the Ebola virus.

Objectives:

To see if MAb114 is safe and how a person's body responds to it.

Eligibility:

Healthy adults ages 18-60 who weigh 220.5 pounds or less

Design:

Participants will be screened under protocol NIH 11-I-0164 with:

  • Medical history
  • Physical exam
  • Blood or urine tests

Participants will have a first 8- to10-hour visit. They will get MAb114 by IV infusion. For this, a thin tube will be placed in an arm vein. They may get an IV line in their other arm to collect blood. Blood will be taken many times before and after the infusion. Participants may have a urine test.

Participants will get a thermometer to check their temperature for 3 days after they get MAb114. They will record their highest temperature and any symptoms.

Participants will have about 14 more study visits over 6 months. At each visit, they will have blood taken and be checked for any health changes. They will talk about how they are feeling and if they have taken any medications.

At the end of the 6 months, participants may be invited to take part in another study for follow-up sample collection.

VRC 608: A Phase I, Open-Label, Dose-Escalation Study of the Safety and Pharmacokinetics of a Human Monoclonal Antibody, VRC-EBOMAB092-00-AB (MAb114), Administered Intravenously to Healthy Adults

Study Design: VRC 608 is the first-in-human Phase I study to examine safety, tolerability and pharmacokinetics of the monoclonal antibody (MAb), VRC-EBOMAB092-00-AB (MAb114). MAb114 will be administered as a single dose. The hypotheses are: 1) MAb114 administration to healthy adults will be safe by the intravenous (IV) route; and 2) MAb114 will be detectable in human sera with a definable half-life. The primary objectives are to evaluate the safety and tolerability of MAb114 in healthy adults. Secondary objectives will evaluate the pharmacokinetics of MAb114 and the potential to detect an anti-drug antibody response to MAb114.

Product Description: MAb114 is a human IgG1 MAb targeted to the Zaire ebolavirus (EBOV) glycoprotein (GP). It was developed by the VRC/NIAID/NIH and manufactured at Cook Pharmica LLC d.b.a. Catalent Indiana, LLC (Bloomington, IN) under current Good Manufacturing Practice (cGMP) regulations. MAb114 is supplied as a lyophilized product in a glass vial at 400 mg per vial with target overfill to 425 mg per vial.

Subjects: Up to 30 healthy adults, 18-60 years of age.

Study Plan: This is an open-label, dose-escalation study of MAb114 administered by IV infusion at dosages of 5, 25 and 50 mg/kg (Groups 1-3). Enrollment will begin with the lowest dose group. Following the first product administration in each group, the study team will wait at least 3 days before administering MAb114 to a second subject within the same group. Dose-escalation evaluations will occur to ensure the safety data support proceeding to the higher doses. Solicited reactogenicity following product administration will be evaluated using a 3-day diary. Assessment of safety will include clinical observation and monitoring of serum hematological and chemical parameters at defined timepoints throughout the study.

  • Group 1: 3 subjects; 5 mg/kg IV
  • Group 2: 5 subjects; 25 mg/kg IV
  • Group 3: 10 subjects; 50 mg/kg IV
  • Total* 18 subjects

    • A minimum of 18 subjects will be enrolled. Enrollment up to a total of 30 subjects is permitted if additional subjects are necessary for safety or pharmacokinetic (PK) evaluations.

Study Duration: Subjects will be followed for 24 weeks after the study product administration.
