Brief Summary:
This study is designed to assess the safety and pharmacokinetic profile of 800 mg Trogarzo once every two weeks administered via "IV Push" or intramuscular injection. An initial "Sentinel Group" of 5 participants will begin receiving 800mg Trogarzo on a gradual schedule of increasing concentration and decreasing administration time until undiluted IV Push over 30 seconds is achieved, while safety and pharmacokinetics are evaluated. If no safety signals are seen, the Core Group of 15 participants will be enrolled. The Core Group will receive 800mg Trogarzo via undiluted IV Push over 30 seconds while safety and pharmacokinetics are monitored. After completion of the IV Push portion of the study, a second group of 20 participants will be enrolled to evaluate the safety and pharmacokinetics of administration of 800mg via intramuscular injection.

Condition or disease Intervention/treatment Phase
HIV-1-infection Drug: ibalizumab-uiyk Phase 3

Detailed Description:

This goal of this Phase 3 is to evaluate the safety and pharmacokinetics of administering Trogarzo 800 mg once every two weeks as an undiluted IV Push over 30 seconds, and as an intramuscular injection in clinically stable HIV-1 infected patients currently receiving treatment with a stable Trogarzo-containing regimen and in healthy volunteers.

The first five (5) patients enrolled will comprise the Sentinel Group. Patients six (6) through twenty (20) (the Core Group) will not be screened until the Sentinel Group has completed Day 99 (14 weeks) of the study and the DSMB has reviewed the data accumulated and given approval for enrollment of the Core Group to proceed.

The Sentinel Group will receive 2 successive doses of Trogarzo in accordance with the prescribing information. Safety and pharmacokinetic data from these administrations will serve as the comparator for each study participant. Beginning at Day 29 and continuing through Day 85, Sentinel Group participants will begin receiving the prescribed dosage of Trogarzo once every two weeks through Day 85 of the study on a schedule of increasing drug concentration and decreasing administration time at each visit to achieve an undiluted IV Push administration of Trogarzo over 30 seconds.

After review of data from the Sentinel Group by a DSMB, if approved the study will continue with enrollment of the Core Group, which will enroll both clinically stable HIV-infected patients on a stable Trogarzo-containing treatment regimen and healthy volunteers. The HIV-infected participants in the Core Group will receive 2 successive doses of Trogarzo in accordance with the prescribing information. Safety and pharmacokinetic data from these administrations will serve as the comparator for each study participant. Thereafter, HIV-infected participants in the Core Group will receive the prescribed dosage of Trogarzo via undiluted IV Push over 30 seconds through Day 71 of the study.

Healthy Volunteers in the Core Group will receive a single loading dose of 2000mg of Trogarzo, followed by three successive doses of 800mg Trogarzo in accordance with the prescribing information in order to reach steady state before pharmacokinetic data for analysis are collected. Thereafter, Healthy Volunteers in the Core Group will follow the same schedule of drug administration and assessments as the HIV-infected participants in the Core Group.

HIV-infected participants in the Intramuscular Injection Group will receive 2 successive doses of Trogarzo in accordance with the prescribing information. Safety and pharmacokinetic data from these administrations will serve as the comparator for each study participant. Thereafter, HIV-infected Intramuscular Injection Group participants will receive the prescribed dosage of Trogarzo via intramuscular injection beginning at Day 29 and continuing through Day 71.

Healthy Volunteers in the Intramuscular Injection Group will receive a single loading dose of 2000mg of Trogarzo, followed by three successive doses of 800mg Trogarzo in accordance with the prescribing information in order to reach steady state before pharmacokinetic data for analysis are collected. Thereafter, Healthy Volunteers in the Intramuscular Injection Group will follow the same schedule of drug administration and assessments as the HIV-infected participants in the Intramuscular Injection Group.
