Since the outbreak of the novel coronavirus disease in 2019 (COVID-19), an unprecedented global search for potential therapeutics and vaccines is ongoing. In this study, a combination of two drugs that have been shown to be effective against the germ that causes COVID-19 in the laboratory will be tested in patients diagnosed with moderate to severe COVID-19. One of the drugs is called nitazoxanide and the second is atazanavir/ritonavir. Nitazoxanide has been used for the treatment of diarrhea since 2004 while atazanavir/ritonavir was approved for HIV treatment in 2003. They are known to be safe in humans.
In this pilot study, 98 COVID-19 patients will be recruited into two groups. The 49 patients in group 1 will receive the standard of care determined by their primary care providers while the 49 patients in group 2 will receive both the standard of care combined with the two study drugs. Patients in group 2 will receive the study drugs for 14 days and all patients will be monitored for a total of 28 days.
The time it takes for the germ that causes COVID-19 to be completely removed from the body (in nasal secretions) and the time to clinical improvement will be monitored in all patients and compared between the two groups.

Randomized, Non-inferiority Trial Comparing a Dual Maintenance Therapy Strategy With Dolutegravir + Lamivudine (DTG/3TC) or Atazanavir/Ritonavir + Lamivudine (ATV/r+3TC) Versus the Standard WHO First Line Triple Therapy Tenofovir + Lamivudine + Efavirenz (TDF+3TC+EFV) or Dolutegravir + Lamivudine + Tenofovir (DTG+3TC+TDF) in West and Central African HIV-1 Infected Patients

MODERATO is a phase III, open-label, randomized, multicenter, non-inferiority trial conducted in West and Central Africa (Cameroon, Côte d'Ivoire, Burkina Faso).
HIV-1 infected adults receiving first line ART with TDF+XTC+EFV or DTG+XTC+TDF virologically suppressed will be recruited and followed during 100 weeks.
The objective is to assess the non-inferiority of a strategy consisting of switching to a dual maintenance therapy (DTG+3TC or ATV/r+3TC), comparing to WHO standard first line regimen (TDF+3TC+EFV or DTG+3TC+TDF), in terms of virological success at 96 weeks

BACKGROUND:

Treatment simplification strategies involving induction with a ritonavir (RTV)-boosted (/r) protease inhibitor regimen followed by simplification (without RTV) are appealing because they may offer sustained virologic suppression while minimizing potential long-term adverse effects associated with RTV.

METHODS:

This open-label, randomized, noninferiority study enrolled 515 antiretroviral therapy-naive patients to receive abacavir/lamivudine plus atazanavir/RTV (ATV/r) followed by randomization at week 36 (N = 419) to maintain or discontinue RTV for an additional 48 weeks. Eligibility for randomization required confirmed HIV RNA level below 50 copies/ml and no virologic failure. Protocol-defined virologic failure after week 36 was confirmed rebound of HIV RNA level at least 400 copies/ml. The primary endpoint was the proportion of patients with HIV RNA level below 50 copies/ml at week 84 (time to loss of virologic response). This study is registered with ClinicalTrials.gov number NCT00440947.

RESULTS:

At week 84, noninferiority of ATV to ATV/r (95% confidence interval around the treatment difference -1.75 to 12.48%) was demonstrated with 181 of 210 (86%) patients in the ATV group and 169 of 209 (81%) in the ATV/r group maintaining HIV RNA level below 50 copies/ml. During the randomized phase (weeks 36-84), 10 versus 14% of patients in the ATV and ATV/r arms, respectively, experienced a drug-related grades 2-4 adverse event with hyperbilirubinemia being the most frequently reported (4 versus 10%). The overall rate of protocol-defined virologic failure was 2%; no patient had virus that developed a major protease inhibitor mutation.

CONCLUSION:

ATV in combination with abacavir/lamivudine is a potent and well tolerated regimen in patients who have achieved initial suppression on an induction regimen and represents a viable treatment simplification strategy.

Once-Daily Abacavir/Lamivudine and Ritonavir-Boosted Atazanavir for the Treatment of HIV-1 Infection in Antiretroviral-Naïve Patients: A 48-Week Pilot Study

Article

Author: Marty St. Clair ; Daniel Berger ; Gary Richmond ; Richard Elion ; William Towner ; Michael Sension ; Belinda Ha ; Edwin deJesus ; Linda Yau

PURPOSE:

To assess the efficacy and safety of a once-daily (QD) regimen consisting of the co-formulation of abacavir/lamivudine (ABC/3TC) and atazanavir plus ritonavir (ATV-RTV) in antiretroviral (ART)-naïve patients with plasma HIV-1 RNA >5,000 copies/mL.

METHOD:

This open-label, multicenter study conducted between September 2004 and June 2006 included 112 patients who received ABC 600 mg/3TC 300 mg and ATV 300 mg-RTV 100 mg QD. Drug switches were permitted for ABC hypersensitivity and ATV-related hyperbilirubinemia. Primary endpoints were proportion of patients achieving HIV-1 RNA <50 copies/mL at Week 48 and treatment discontinuation due to study drugs.

RESULTS:

A total of 111 patients were treated. At Week 48, the proportion of patients achieving HIV-1 RNA <50 copies/mL was 77% (85/111) by intent-to-treat (ITT) missing=failure, switch included response rate. Drug substitutions occurred in 8 (7%) patients for suspected ABC hypersensitivity reaction (HSR) and in 6 (5%) patients for ATV-related toxicities; only 1 patient discontinued study due to ABC HSR. Four patients met confirmed virologic nonresponse (HIV RNA >or= 400 copies/mL). Treatment-emergent drug resistance was rare, and no patient had virus that developed reduced susceptibility to ATV. Median change from baseline (95% confidence interval) in fasting lipids at Week 48 was 39 (26-66) mg/dL for triglycerides, 28 (22-38) mg/dL for total cholesterol (C), 14 (10.5-16) mg/dL for HDL-C, and 8 (2-16.5) mg/dL for LDL-C.

CONCLUSION:

ABC/3TC and ATV-RTV QD is an effective and well-tolerated regimen in ART-naïve patients through 48 weeks, with a modest impact on fasting lipids.

Identification of Malaria-Selective Proteasome β5 Inhibitors Through Pharmacophore Modeling, Molecular Docking, and Molecular Dynamics Simulation

Article

Author: Han, Eun-Taek ; Han, Jin-Hee ; Yasir, Muhammad ; Park, Jinyoung ; Chun, Wanjoo ; Park, Won Sun

Malaria remains a global health challenge, with increasing resistance to frontline antimalarial treatments such as artemisinin (ART) threatening the efficacy of current therapies. In this study, we investigated the potential of FDA-approved drugs to selectively inhibit the malarial proteasome, a novel target for antimalarial drug development. By leveraging pharmacophore modeling, molecular docking, molecular dynamics (MD) simulations, and binding free-energy calculations, we screened a library of compounds to identify inhibitors selective for the Plasmodium proteasome over the human proteasome. Our results highlighted Argatroban, LM-3632, Atazanavir Sulfate, and Pemetrexed Hydrate as promising candidates, with Argatroban and Pemetrexed Hydrate showing the highest binding affinity and selectivity toward the malarial proteasome. MD simulation and gmx_MMPBSA analysis confirmed the compounds’ ability to remain within the active site of the malarial proteasome, while some exited or exhibited reduced stability within the human proteasome. This study underscores the potential of proteasome-targeting drugs for overcoming malarial drug resistance and paves the way for the further optimization of these compounds.
