NCT05850728

Brief Summary

This study is a prospective, open-label, single-site, first-in-human study of a long-acting, injectable combination antiretroviral therapy platform, with a pharmacologically-guided adaptive design for dose escalation, de-escalation, and study duration. The study is designed to learn whether the formulation can be used as a platform for other drugs for treatment of HIV. The formulation is a drug combination nanoparticle (DCNP). The study will be conducted by UW Positive Research. The sample size for this study is 12-16. The study population consists of healthy adults without HIV. The study duration is 57 days per participant at the start of the study.

Study Arms (5)

TLC-ART 101 Initial Dosage

EXPERIMENTAL

The arms will all receive the nanoparticle suspension of lopinavir, ritonavir, and tenofovir (TLC-ART 101). The arms are also called cohorts. The dose a participant receives will vary, depending upon the study results and the time of when they enroll in the study. The initial dosage administered to 4 participants will contain: lopinavir 15.6 mg, ritonavir 4.2 mg, and tenofovir 9.15 mg in 1.5mL of the formulation If the initial dose is appropriate, an additional 8 participants will be enrolled in Arm 1, for a total study size of 12 participants.

Drug: TLC-ART

TLC-ART 101 Dosage 2A

EXPERIMENTAL

In the scenario in which the dosage in Arm 1 produces insufficient pharmacokinetics (PK), the dosage will be increased 2 fold in Arm 2A and administered to 4 participants. If Arm 2A shows ideal PK parameters, and additional 8 participants will be enrolled in this arm, for a total study size of 16 participants.

Drug: TLC-ART

TLC-ART 101 Dosage 2B

EXPERIMENTAL

In the scenario in which the dosage in Arm 1 produces excessive drug levels, the dosage will be decreased by up to 2-5 fold (2-5x descending dose) and administered to 4 participants. If Arm 2B shows ideal PK parameters, and additional 8 participants will be enrolled in this arm, for a total study size of 16 participants.

Drug: TLC-ART

TLC-ART 101 Dosage 3A

EXPERIMENTAL

In the scenario in which the dosage in Arm 2A produces insufficient drug levels, the dosage may be further increased by 2-fold from Arm 2A dosage (4x total dosage increase) and administered to an additional 4 participants. If Arm 3A shows ideal PK parameters, and additional 4 participants will be enrolled in this arm, for a total study size of 16 participants

Drug: TLC-ART

TLC-ART 101 Dosage 3B

EXPERIMENTAL

In the scenario in which the dosage in Arm 2B produces excessive drug levels, the dosage may be further decreased further by up to 2-5-fold from Arm 2B dosage (4-10x dose decrease) and administered to 4 participants. If Arm 3B shows ideal PK parameters, and additional 4 participants will be enrolled in this arm, for a total study size of 16 participants

Drug: TLC-ART
