Detailed Description
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 has two primary aims as follows:
- To characterize the plasma concentration-time course and pharmacokinetics (PK) of a single dose of the drug substances of TLC-ART 101 (lopinavir, ritonavir, and tenofovir) administered by subcutaneous injection within the drug combination nanoparticle.
- To characterize the safety and tolerability of a single subcutaneous injection of TLC-ART 101.
There are 4 exploratory mechanistic objectives (with related endpoints) as follows:
- To characterize the pharmacokinetics of the drug substances in human peripheral blood mononuclear cells (PBMCs)
- To characterize the concentrations of intracellular TFV-diphosphate (the active moiety of TFV) in PBMCs
- To explore whether the pharmacokinetic parameters of the 3 drug substances differ by sex following a single dose
- To compare lymphoid tissue mononuclear cell versus PBMC concentrations of the drug substances in TLC-ART 101.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: TLC-ART 101 Initial Dosage
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. |

Experimental: TLC-ART 101 Dosage 2A
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. |
