Study of the Safety of Trogarzo™ Administered as an Undiluted "IV Push" or an Intramuscular Injection

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 Data Safety Monitoring Board (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.
