Brief summary

Background: Malaria is a parasitic disease carried by mosquitoes in tropical areas. There is no vaccine to prevent malaria infection. If not treated right away, it can become serious or deadly. Researchers want to test a drug to prevent malaria. Objective: To test if the drug L9LS is safe and if it prevents malaria infection in people. Eligibility: Healthy adults ages 18-50 who have never had malaria. Design: Participants were screened with a medical history, physical exam, and blood tests. Participants were divided into 6 groups: * Three groups received L9LS by infusion into a vein, and gave blood samples before and after infusion. * One group received L9LS injected into the fat under the skin. * One group did not get L9LS. * One group received L9LS injected into the muscle. All participants who received L9LS were monitored for side effects. They had 2-3 follow-up visits during the week after the drug was given, and gave blood samples. They received a thermometer to check their temperature daily for 7 days. They received a tool to measure any redness, swelling, or bruising at the injection site. Most participants took part in the controlled human malaria infection (CHMI) or malaria challenge to find out if L9LS prevents malaria after being bitten by infected mosquitos. Participants in the group who received L9LS injected in the muscle were enrolled after CHMI and did not take part in the CHMI. Participants who received CHMI were bitten by mosquitoes carrying the malaria parasites. A cup containing mosquitoes was placed on their arm for 5 minutes. On days 7-17 after exposure, they received daily study visits to give blood samples. Those who got malaria were treated immediately. On day 21, all CHMI participants received treatment for malaria. Participation lasted 2-6 months, depending on study group.

Detailed description

This was a Phase 1, open-label, dose escalation study to evaluate the safety, tolerability, pharmacokinetics and protective efficacy of an anti-malaria human monoclonal antibody, VRC-MALMAB0114-00-AB (L9LS). The primary hypothesis was that L9LS will be safe and well tolerated when administered by either intravenous (IV),subcutaneous (SC) or intramuscular (IM) routes. The secondary objectives were that L9LS will be detectable in human sera with a definable half-life and confer protection following a controlled human malaria infection (CHMI). The study started with enrollment into Group 1. Interim safety evaluations occurred and supported continued evaluation of L9LS prior to enrolling participants into additional dose groups. All L9LS recipients in Groups 1-4 were invited to participate in the CHMI. Group 5 participants did not receive L9LS, in order to serve as the control group for the CHMI. After CHMI, all CHMI participants were evaluated for malaria parasitemia. Participants who developed blood stage infection were treated as soon as identified per protocol criteria. Participants in Group 6 received L9LS but did not take part in the CHMI. Study follow-up continued through 24 weeks post product administration or 8 weeks post- CHMI, whichever was the most stringent. Study Groups: Group 1: 5 participants - 1mg/kg IV + CHMI Group 2: 4 participants - 5 mg/kg IV + CHMI (1 participant declined to participate in the CHMI) Group 3: 5 participants - 5 mg/ kg SC + CHMI Group 4: 4 participants - 20 mg/kg IV + CHMI Group 5: 9 participants - CHMI Controls (No L9LS given; 3 back up participants were not needed so were terminated early and did not participate in the CHMI) Group 6: 5 participants - 5 mg/kg IM

Primary

Number of Participants Reporting Systemic Reactogenicity Signs and Symptoms Within 7 Days of L9LS 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.

Time frame: 7 days after L9LS product administration, at approximately Week 1

Population: Population included all enrolled participants who received L9LS and had safety data collected via diary card (N=23). Group 5 CHMI controls did not receive L9LS.

Pharmacokinetic (PK) Parameters of L9LS: Volume of Distribution at Steady-State (Vss/F) Following SC or IM Administration

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 SC and IM group. Volume of distribution at steady-state (Vss) following a SC or IM administration is calculated as Volume of distribution at steady-state (Vss)/Bioavailability (F).

Time frame: Baseline through 24 weeks after L9LS product administration

Population: Population included participants who received either L9LS (5 mg/kg SC and 5 mg/kg IM) subcutaneously or intramuscularly (N=10).
