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.

NCT04022967 / Active, not recruitingPhase 3IIT

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

BACKGROUNDTreatment 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.METHODSThis 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.RESULTSAt 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.CONCLUSIONATV 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

PURPOSETo 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.METHODThis 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.RESULTSA 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.CONCLUSIONABC/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.
