Project description:BackgroundNo therapeutics have yet been proven effective for the treatment of severe illness caused by SARS-CoV-2.MethodsWe conducted a randomized, controlled, open-label trial involving hospitalized adult patients with confirmed SARS-CoV-2 infection, which causes the respiratory illness Covid-19, and an oxygen saturation (Sao2) of 94% or less while they were breathing ambient air or a ratio of the partial pressure of oxygen (Pao2) to the fraction of inspired oxygen (Fio2) of less than 300 mm Hg. Patients were randomly assigned in a 1:1 ratio to receive either lopinavir-ritonavir (400 mg and 100 mg, respectively) twice a day for 14 days, in addition to standard care, or standard care alone. The primary end point was the time to clinical improvement, defined as the time from randomization to either an improvement of two points on a seven-category ordinal scale or discharge from the hospital, whichever came first.ResultsA total of 199 patients with laboratory-confirmed SARS-CoV-2 infection underwent randomization; 99 were assigned to the lopinavir-ritonavir group, and 100 to the standard-care group. Treatment with lopinavir-ritonavir was not associated with a difference from standard care in the time to clinical improvement (hazard ratio for clinical improvement, 1.31; 95% confidence interval [CI], 0.95 to 1.80). Mortality at 28 days was similar in the lopinavir-ritonavir group and the standard-care group (19.2% vs. 25.0%; difference, -5.8 percentage points; 95% CI, -17.3 to 5.7). The percentages of patients with detectable viral RNA at various time points were similar. In a modified intention-to-treat analysis, lopinavir-ritonavir led to a median time to clinical improvement that was shorter by 1 day than that observed with standard care (hazard ratio, 1.39; 95% CI, 1.00 to 1.91). Gastrointestinal adverse events were more common in the lopinavir-ritonavir group, but serious adverse events were more common in the standard-care group. Lopinavir-ritonavir treatment was stopped early in 13 patients (13.8%) because of adverse events.ConclusionsIn hospitalized adult patients with severe Covid-19, no benefit was observed with lopinavir-ritonavir treatment beyond standard care. Future trials in patients with severe illness may help to confirm or exclude the possibility of a treatment benefit.

Project description:BackgroundNevirapine-based antiretroviral therapy is the predominant (and often the only) regimen available for children in resource-limited settings. Nevirapine resistance after exposure to the drug for prevention of maternal-to-child human immunodeficiency virus (HIV) transmission is common, a problem that has led to the recommendation of ritonavir-boosted lopinavir in such settings. Regardless of whether there has been prior exposure to nevirapine, the performance of nevirapine versus ritonavir-boosted lopinavir in young children has not been rigorously established.MethodsIn a randomized trial conducted in six African countries and India, we compared the initiation of HIV treatment with zidovudine, lamivudine, and either nevirapine or ritonavir-boosted lopinavir in HIV-infected children 2 to 36 months of age who had no prior exposure to nevirapine. The primary end point was virologic failure or discontinuation of treatment by study week 24.ResultsA total of 288 children were enrolled; the median percentage of CD4+ T cells was 15%, and the median plasma HIV type 1 (HIV-1) RNA level was 5.7 log(10) copies per milliliter. The percentage of children who reached the primary end point was significantly higher in the nevirapine group than in the ritonavir-boosted lopinavir group (40.8% vs. 19.3%; P<0.001). Among the nevirapine-treated children with virologic failure for whom data on resistance were available, more than half (19 of 32) had resistance at the time of virologic failure. In addition, the time to a protocol-defined toxicity end point was shorter in the nevirapine group (P=0.04), as was the time to death (P=0.06).ConclusionsOutcomes were superior with ritonavir-boosted lopinavir among young children with no prior exposure to nevirapine. Factors that may have contributed to the suboptimal results with nevirapine include elevated viral load at baseline, selection for nevirapine resistance, background regimen of nucleoside reverse-transcriptase inhibitors, and the standard ramp-up dosing strategy. The results of this trial present policymakers with difficult choices. (Funded by the National Institute of Allergy and Infectious Diseases and others; P1060 ClinicalTrials.gov number, NCT00307151.).

Project description:ObjectiveTo develop a population pharmacokinetic model for lopinavir boosted by ritonavir in coronavirus disease 2019 (Covid-19) patients.MethodsConcentrations of lopinavir/ritonavir were assayed by an accredited LC-MS/MS method. The population pharmacokinetics of lopinavir was described using non-linear mixed-effects modeling (NONMEM version 7.4). After determination of the base model that better described the data set, the influence of covariates (age, body weight, height, body mass index (BMI), gender, creatinine, aspartate aminotransferase (AST), alanine aminotransferase (ALT), C reactive protein (CRP), and trough ritonavir concentrations) was tested on the model.ResultsFrom 13 hospitalized patients (4 females, 9 males, age = 64 ± 16 years), 70 lopinavir/ritonavir plasma concentrations were available for analysis. The data were best described by a one-compartment model with a first-order input (KA). Among the covariates tested on the PK parameters, only the ritonavir trough concentrations had a significant effect on CL/F and improved the fit. Model-based simulations with the final parameter estimates under a regimen lopinavir/ritonavir 400/100 mg b.i.d. showed a high variability with median concentration between 20 and 30 mg/L (Cmin/Cmax) and the 90% prediction intervals within the range 1-100 mg/L.ConclusionAccording to the estimated 50% effective concentration of lopinavir against SARS-CoV-2 virus in Vero E6 cells (16.7 mg/L), our model showed that at steady state, a dose of 400 mg b.i.d. led to 40% of patients below the minimum effective concentration while a dose of 1200 mg b.i.d. will reduce this proportion to 22%.

Project description:ObjectivesThere was initially insufficient understanding regarding suitable pharmacological treatment for pediatric Coronavirus Disease 2019 (COVID-19) patients. Lopinavir-ritonavir (LPV/r) was originally used for the treatment of Human Immunodeficiency Virus-1 (HIV-1) infection. It was also used in patients with severe acute respiratory syndrome (SARS) and Middle East Respiratory Syndrome (MERS) with positive results. Nonetheless, results from recent randomized controlled trials and observational studies on COVID-19 patients were unfavorable. We sought to evaluate the clinical outcomes associated with early treatment with LPV/r for pediatric COVID-19 patients.Study designA total of 933 COVID-19 patients aged ≤ 18 years were admitted between 21 January 2020 and 31 January 2021 in Hong Kong. Exposure was receiving LPV/r within the first two days of admission. Time to clinical improvement, hospital discharge, seroconversion and hyperinflammatory syndrome, cumulative costs, and hospital length of stay were assessed. Multivariable Cox proportional hazard and linear models were performed to estimate hazard ratios (HR) and their 95% confidence intervals (CI) of time-to-event and continuous outcomes, respectively.ResultsLPV/r users were associated with longer time to clinical improvement (HR 0.51, 95% CI 0.38-0.70; p < 0.001), hospital discharge (HR 0.51, 95% CI 0.38-0.70; p < 0.001) and seroconversion (HR 0.59, 95% CI 0.43-0.80; p < 0.001) when compared with controls. LPV/r users were also associated with prolonged hospital length of stay (6.99 days, 95% CI 6.23-7.76; p < 0.001) and higher costs at 30 days (US$11,709 vs US$8270; p < 0.001) as opposed to controls.ConclusionEarly treatment with LPV/r for pediatric COVID-19 patients was associated with longer time to clinical improvement. Our study advocates the recommendation against LPV/r use for pediatric patients across age groups.

Project description:BackgroundAlbuvirtide (ABT), a fusion inhibitor against human immunodeficiency virus (HIV) infection, has good efficacy and tolerability for HIV treatment. However, there is a paucity of data regarding ABT-based regimen as second-line therapy. This current study evaluated the efficacy and safety of switching to ABT + ritonavir-boosted lopinavir (LPV/r) treatment in a cohort of HIV-infected individuals who failed initial treatment.MethodsThis retrospective comparative cohort study included patients who failed initial treatment and switched to either ABT + LPV/r (the ABT group) or two nucleotide reverse transcriptase inhibitors (NRTIs) + LPV/r (the NRTI group) between November 2019 and December 2020 in the People's Hospital of Zhaojue County in Liangshan Yi Autonomous Prefecture, China. All individuals were followed up from baseline to 12 weeks after conversion, or until the patient developed unacceptable toxic effects or was loss of follow-up. The proportion of patients who achieved virological suppression (viral load <50 copies/mL) at week 12 was considered a primary efficacy endpoint. Safety outcomes included the incidence of adverse events and laboratory abnormalities. All participants underwent resistance testing before regimen conversion. The linear regression model was applied to evaluate the association of CD4+ T cell count with the patient's clinical characteristics.ResultsA total of 71 patients were included in this study, the two groups were comparable at baseline in terms of age, sex, CD4+ T cell count, and viral load. The suppression of HIV-1 RNA to levels <50 copies/mL was achieved in 82.4% (28/31) and 29.7% (11/34) of patients in the ABT group and the NRTI group, respectively (P<0.001). Older age (P=0.016) and higher alkaline phosphatase (ALP) levels (P=0.038), but not rescue regimen, were associated with attenuated CD4+ T cell recovery. Most adverse events mild in severity, with abdominal pain as the most reported event in two groups (26.8%, 19/71), and no severe adverse events were detected.ConclusionsConversion to ABT + LPV/r therapy appears to be an effective and safe strategy. This treatment regimen has great potential to be generalized in the HIV-infected population, although further testing in a larger patient population is required to verify these results.

Project description:Following the first case of Coronavirus Disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-Cov-2), in Wuhan, China, in December 2019, it has spread worldwide. An outbreak in Japan occurred on a cruise ship, and this was followed by community-acquired COVID-19. Herein, we report three cases of COVID-19 that presented pneumonia following admission to Kitasato University Hospital. Patients were admitted based on the positive result of real-time reverse transcriptase–polymerase chain reaction (RT-PCR) tests for COVID-19 nucleic acid. All patients were diagnosed as suffering from non-severe COVID-19 pneumonia and were successfully treated with Lopinavir/Ritonavir (LPV/r). LPV/r could be an option for treating non-severe COVID-19 pneumonia in general and even in elderly patients.

Project description:Currently, there is no specific antiviral treatment for COVID-19. However, drugs previously developed to treat other viral infections are being tested to verify if they might also be effective against SARS-CoV-2, the virus that causes COVID-19. Twenty years ago, the F.D.A. approved Lopinavir/ritonavir (LPV/r) to treat HIV infection. LPV and ritonavir were initially purposed to inhibit 3-chymotrypsin-like protease (3CLpro) of SARS-CoV and MERS-CoV and preliminary promising data on its efficacy for treating people infected with those viruses were available. Therefore, due to the high genetic similarities among those viruses and SARS-CoV-2, early during COVID-19 pandemic LPV/r was also proposed as one emergency treatment. We reviewed data from the literature about LPV/r treatment and SARS-CoV-2 infection, mainly focused on the efficacy and safety of this drugs for COVID-19 treatment. We can conclude that although up to date no clear benefit has been observed with the LPV/r treatment beyond standard care, its efficacy against SARS-COV-2 infection deserves further evaluations, particularly during the very early phase of the disease.
