Brief summary

The trial Safety, Pharmacokinetics and Preliminary Efficacy of herbal products for the treatment of acute respiratory viral infections including SARS-CoV2 in Uganda; Phase 2A Open Label Clinical Trial is currently being implemented under the Clinical Trials of Natural therapeutics Program. The trial sample size is 510, and the participants include adults (18 years or more) who fulfill the case definitions of acute respiratory infections (ARI), test positive for one of the target respiratory viruses, are negative for TB on GeneXpert; non-pregnant/non-breast-feeding females, have no history of hypersensitivity to any of the investigational products, and have given written consent to participate in the trial. The overall objective of the trial is to assess the safety, pharmacokinetics and preliminary efficacy of TazCoV and Vidicine for the treatment of acute respiratory viral infections including (SARS-CoV2, RSV and Influenza A/B) in Uganda. Primary objectives include: 1. To determine the safety and pharmacokinetics of TAZCOV and Vidicine herbal products among adult participants patients with acute respiratory infections including those due to laboratory-confirmed SARS-CoV2, RSV and Influenza A/B 2. To determine the extent of SARS-CoV2, RSV, and Influenza A/B viral clearance among adult participants patients with acute viral respiratory infection treated using TAZCOV and Vidicine 3. To establish time-to-remission of symptoms among participants patients with acute respiratory infections including those due to laboratory-confirmed SARS-CoV2, RSV and Influenza treated with TAZCOV or Vidicine 4. To evaluate disease progression among participants patients with acute respiratory infections including those due to laboratory-confirmed SARS-CoV2, RSV and Influenza treated with TAZCOV or Vidicine The end points include: Solicited and unsolicited side effects (mild, moderate, severe, adverse and serious adverse events), days to viral clearance (RT-PCR negativity) for those with a positive viral test at enrolment and time to presenting symptom resolution. The Pharmacokinetic endpoints include: the maximum concentration of IMP in plasma \[Cmax\], time taken for the IMP plasma concentration to reach maximum levels \[Tmax\] and time taken for the concentration of the IMP in the plasma or the total amount in the body to be reduced by 50%.

Design outcomes

Primary

MeasureTime frameDescription
Solicited and unsolicited side effects (mild, moderate, severe, adverse and serious adverse events).9 monthsThe outcome measures are cumulative incidences of solicited and unsolicited side effects (mild, moderate, severe adverse events) in the study arms
Time to presenting symptom resolution14 daysWill be assessed by time trends in clinical remission of signs and symptoms in the trial arms
Days to viral clearance (RT-PCR negativity) for those with a positive viral test at enrolment7 daysWill be assessed through ascertaining the proportion with negative PCR on days 3, 5 and 7
Progression to severe-critical ARI requiring hospitalization, oxygen therapy and/or mortality14 daysTo be measured by ascertaining the proportion progressing to severe ARI requiring hospitalization, oxygen therapy and/or mortality
Time taken for TazCoV and Vidicine plasma concentration to reach maximum levels [Tmax]14 daysTo be measured by time to maximum concentration of TazCoV and Vidicine plasma \[Tmax\]
