Phase Ib/IIa Clinical Study of ACC017 Tablets

ACC017 is an integrase inhibitor that will be evaluated for the treatment of HIV infection. This phase Ib/IIa, randomized, double-blind, parallel, dose ranging, placebo-controlled 'proof of concept' study is designed to evaluate the safety, tolerability, pharmacokinetics and antiviral effect of ACC017 monotherapy and combined with FTC/TAF by sequency versus placebo in treatment-naïve HIV-1 infected adults. This study includes two stages, stage one is a single dose escalation, and all subjects will be co-administrated with FTC/TAF at 200 mg/25 mg on stage two. The study consists of a screening visit, baseline period, monotherapy period, and combination therapy period. Total 36 subjects will be randomized in a 5:1 ratio to receive one of three doses of ACC017 or placebo lasting for 10 days for monotherapy followed by 18 days for combination therapy.

Efficacy and Safety of the ACC017-Based Antiretroviral Regimen in Treatment-Experienced Adults With HIV-1 Harboring Non-Nucleoside Reverse Transcriptase Inhibitor Resistance Mutations

This trial is a randomized, double-blind, placebo-controlled clinical study conducted in treatment-experienced adults with NNRTI-resistant HIV-1, designed to preliminarily evaluate the efficacy, safety, and resistance profile of the core drug ACC017 in this population. The study consists of two treatment phases: a functional monotherapy period (double-blind phase) and an extended optimized treatment period (open-label phase). The first phase is the functional monotherapy period (W1-W2). After initial screening, eligible participants will return to the hospital on D1 for final eligibility review and baseline examinations. Those who pass the review will be randomized in a 2:1 ratio to either ACC017 tablets (N=8, 40 mg, once daily \[QD\]) or matching placebo (N=4), replacing the core NNRTI drug in the failing background regimen while maintaining the original backbone NRTIs unchanged. Treatment will continue for 2 weeks. The second phase is the extended optimized treatment period (W3-W16). All participants who complete the functional monotherapy period will receive ACC017 tablets (40 mg QD) in combination with an optimized backbone regimen (i.e., ACC017 replaces the core NNRTI drug in the failing background regimen, while the investigator adjusts the backbone drugs based on HIV genotypic resistance test results to ensure at least one backbone NRTI remains sensitive, if applicable). Treatment will continue for 14 weeks.

Study Evaluating the Efficacy, Safety, and Tolerability of Switching to Long-acting Cabotegravir Plus Long-acting Rilpivirine From Current Antiretroviral Regimen in Virologically Suppressed HIV-1-infected Adults

The Antiretroviral Therapy as Long Acting Suppression (ATLAS) study is being conducted to establish if human immunodeficiency virus type-1 (HIV-1) infected adult subjects with current viral suppression on a regimen with 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus a third agent, remain suppressed upon switching to a two-drug intramuscular (IM) long-acting (LA) regimen of cabotegravir (CAB) and rilpivirine (RPV). This is a Phase 3, multi-phase, randomized, open label, active-controlled, multicenter, parallel-group, non-inferiority study in HIV-1, antiretroviral therapy (ART)-adult subjects who are stably suppressed on a current antiretroviral (ARV) regimen. This study is designed to demonstrate the non-inferior antiviral activity of switching to a two drug CAB LA 400 mg + RPV LA 600 mg regimen every 4 weeks (Q4W: monthly) compared with maintenance of current ARV regimen containing 2 NRTIs plus an INI, NNRTI, or a PI. Eligible subjects will be randomized (1:1) into the Maintenance Phase at Day 1 to either continue current ART or switch to initiate oral therapy with CAB 30 mg + RPV 25 mg once daily for 4 Weeks followed by Q4 weekly (monthly) CAB LA + RPV LA injections. Following the Maintenance phase at Week 52, subjects who were randomized to continue their current ART regimen will be given an option to switch to CAB LA + RPV LA injections. Those subjects would transition to LA dosing, beginning with 4 weeks oral CAB + RPV therapy at Week 52, and receive the first IM CAB LA + RPV LA injections at Week 56.
