Direct Initiation of Long-Acting Cabotegravir Plus Rilpivirine in People with HIV and Suboptimal Virologic Suppression: A Randomized Trial.

BACKGROUND: Long-acting injectable cabotegravir plus rilpivirine (LA CAB+RPV) is approved for virally suppressed people with human immunodeficiency virus (HIV), but evidence for its use in those with persistent viremia and adherence challenges remains limited. METHODS: We conducted a multicenter, open-label, randomized study involving oral antiretroviral therapy (ART)-experienced people with HIV who had been diagnosed with HIV for at least 12 months and a most recent HIV-1 RNA level of at least 200 copies per milliliter. Participants with resistance-associated mutations to CAB or RPV were excluded. Eligible participants were randomly assigned in a 1:1 ratio to receive immediate LA CAB+RPV or to continue standard oral therapy until Week 24 (delayed switch group). The primary endpoint was the proportion of participants with an HIV-1 RNA level of less than 200 copies per milliliter at Week 24. RESULTS: Of 61 randomized participants, 45 met eligibility criteria and were included in the analysis; 91% were male, and the median baseline HIV-1 RNA was 35,000 copies/mL. At Week 24, viral suppression was achieved in 88.0% (22/25) in the immediate LA group versus 55.0% (11/20) in the delayed switch group (relative risk for failure to achieve viral suppression, 0.27; 95% CI, 0.08-0.86; p = 0.026). The effect of LA CAB+RPV was sustained through Week 52. CONCLUSIONS: Among people with HIV and viremia associated with adherence challenges, immediate initiation of LA CAB+RPV resulted in higher rates of viral suppression than continued oral ART, supporting its use beyond populations with stable suppression.

In search of a novel anti-HIV drug: multidisciplinary coordination in the discovery of 4-[[4-[[4-[(1E)-2-cyanoethenyl]-2,6-dimethylphenyl]amino]-2- pyrimidinyl]amino]benzonitrile (R278474, rilpivirine).

Ideally, an anti-HIV drug should (1) be highly active against wild-type and mutant HIV without allowing breakthrough; (2) have high oral bioavailability and long elimination half-life, allowing once-daily oral treatment at low doses; (3) have minimal adverse effects; and (4) be easy to synthesize and formulate. R278474, a new diarylpyrimidine (DAPY) non-nucleoside reverse transcriptase inhibitor (NNRTI), appears to meet these criteria and to be suitable for high compliance oral treatment of HIV-1 infection. The discovery of R278474 was the result of a coordinated multidisciplinary effort involving medicinal chemists, virologists, crystallographers, molecular modelers, toxicologists, analytical chemists, pharmacists, and many others.

Emerging anti-HIV drugs.

There are now exactly 20 anti-HIV drugs licenced (approved) for clinical use, and > 30 anti-HIV compounds under (pre)clinical development. The licensed anti-HIV drugs fall into five categories: nucleoside reverse transcriptase inhibitors (NRTIs: zidovudine, didanosine, zalcitabine, stavudine, lamivudine, abacavir and emtricitabine); nucleotide reverse transcriptase inhibitors (NtRTIs: tenofovir disoproxil fumarate); non-nucleoside reverse transcriptase inhibitors (NNRTIs: nevirapine, delavirdine and efavirenz); protease inhibitors (PIs: saquinavir, indinavir, ritonavir, nelfinavir, amprenavir, lopinavir, atazanavir and fosamprenavir); and fusion inhibitors (FIs: enfuvirtide). The compounds that are currently under clinical (Phase I, II or III) or preclinical investigation are either targeted at the same specific viral proteins as the licensed compounds (i.e., reverse transcriptase [NRTIs: PSI-5004, (-)-dOTC, DPC-817, elvucitabine, alovudine, MIV-210, amdoxovir, DOT; NNRTIs: thiocarboxanilide, UC-781, capravirine, dapivirine, etravirine, rilpivirine], protease [PIs: tipranavir, TMC-114]) or other specific viral proteins (i.e., gp120: cyanovirin N; attachment inhibitors: AIs, such as BMS-488043; integrase: L-870,812, PDPV-165; capsid proteins: PA-457, alpha-HCG); or cellular proteins (CD4 downmodulators: CADAs; CXCR4 antagonists: AMD-070, CS-3955; CCR5 antagonists: TAK-220, SCH-D, AK-602, UK-427857). Combination therapy is likely to remain the gold standard for the treatment of AIDS so as to maximise potency, minimise toxicity and diminish the risk for resistance development. Ideally, pill burden should be reduced to once-daily dosing so as to optimise the patient's compliance and reduce the treatment costs.

Synthesis of novel diarylpyrimidine analogues of TMC278 and their antiviral activity against HIV-1 wild-type and mutant strains.

Novel diarylpyrimidines (DAPY), which represent next generation of non-nucleoside reverse transcriptase inhibitors (NNRTIs), were synthesized and their activities against human immunodeficiency virus type I (HIV-1) assessed. Modulations at positions 2 and 6 of the left phenyl ring generated interesting derivatives of TMC278 displaying high potency against wild-type and mutant viruses compared to nevirapine and efavirenz. The pharmacokinetic profile of the best newly synthesized DAPY was evaluated and compared with TMC278 now in phase II clinical trials.

Short-term antiviral activity of TMC278--a novel NNRTI--in treatment-naive HIV-1-infected subjects.

OBJECTIVE: To evaluate antiviral activity, pharmacokinetics, tolerability and safety of TMC278, a non-nucleoside reverse transcriptase inhibitor (NNRTI), when given as a 25, 50, 100 or 150 mg once-daily dose for 7 days to antiretroviral-naive HIV-infected subjects. DESIGN: Randomized, double-blind, placebo-controlled, phase IIa clinical trial. METHODS: Participants were 47 antiretroviral naive HIV-infected subjects. Primary outcome was the change in plasma HIV-1 RNA viral load from baseline to day 8. Secondary outcomes were evaluation of pharmacokinetics of TMC278, immunologic changes, safety and tolerability, and evolution of viral genotypic and phenotypic patterns. RESULTS: Patients treated with TMC278 achieved a median decrease in plasma viral load from baseline of 1.199 log10 copies/ml compared with a 0.002 log10 copies/ml gain in the placebo group (P < 0.01). A significantly higher proportion of subjects in the TMC278 groups obtained a viral load decrease of > 1.0 log10 compared with the placebo group (25/36 versus 0/11) (P < 0.01). No significant dose differences were noted in either antiviral effect or safety. No genotypic changes associated with antiretroviral resistance were detected between baseline and the end of the trial. Plasma concentrations of TMC278 were above the target concentration (13.5 ng/ml) at all time points for all TMC278-treated subjects. The most common reported adverse event was headache (TMC278 14%; placebo 18%). CONCLUSIONS: TMC278 showed antiviral activity when given as monotherapy for 7 days at all doses studied and the drug was safe and well tolerated. Trials of longer treatment duration with TMC278, in combination with other antiretroviral drugs, are underway to assess the long-term durability of antiviral response, safety and tolerability.

Behind "AIDS breakthrough" headlines, December 2004: important research, not so new.

The mid-December press reports about an AIDS drug breakthrough were exaggerated, but the research described is important. It concerns the development of a class of related experimental drugs that work like efavirenz or nevirapine, but appear to be more powerful and much less subject to resistance.

[New drugs--hope for salvage patients?].

New and potent drugs are urgently needed for the salvage therapy of HIV-infected patients. The protease inhibitors Tipranavir and TMC114, which have high potency against multidrug-resistant viral strains, are the most promising drugs for the near future. How important they will be in salvage therapy cannot be predicted at this time. New points of attack in the viral replication cycle have been defined. Substances belonging to the groups of integrase and maturation inhibitors are in the early stages of clinical development.

Next-generation HIV-1 non-nucleoside reverse transcriptase inhibitors.

This review discusses the desired attributes of a next-generation HIV-1 non-nucleoside reverse transcriptase inhibitor (NNRTI) and highlights the properties of compounds currently or recently in clinical development. TMC-125 is currently in phase III clinical trials and on track to become the first NNRTI suitable for use in NNRTI-experienced patients. TMC-278 is structurally related to TMC-125, but is more potent in vitro and has pharmacokinetics suitable for once-daily administration. It is currently undergoing phase II clinical trials. BILR-355 BS, a dipyridodiazepinone compound, is in early phase II clinical trials. It requires ritonavir as a booster and has reduced inhibitory activity against several key NNRTI-resistant HIV-1 strains. Development of the NNRTIs capravirine and GW-695634 has been discontinued because of lack of efficacy and safety issues, respectively.
