- Child, Adult, Older adult
Who may be able to join
- This study will include patients with confirmed COVID-19 infection and admitted to COVID-19 quarantine hospitals. Included patients should be > 12 years old, with creatinine clearance > 30 mL/ml, and without any malignancy. Patients with COVID-19 infection are classified clinically into mild, moderate, severe, and critical cases according to the management guide for COVID-19 published by the Egyptian Ministry of Health and Population. Mild cases are defined as patients in whom clinical symptoms are mild, and no pneumonia manifestations can be found in imaging. Moderate cases are defined as patients having symptoms such as fever and respiratory tract symptoms, etc. and pneumonia manifestations can be seen in imaging. Severe cases are patients who meet any of the following criteria; (a) respiratory rate > 30 breaths/min, (b) oxygen saturations< 93% at a rest state, (c) arterial partial pressure of oxygen (PaO2)/ Fraction of inspired oxygen (FiO2)<300 mm Hg, or (d) patients with more than 50% lesions progression within 24 to 48 hours in lung imaging should be treated as severe cases. Finally, critical patients are those who are meeting any of the following criteria; (a) occurrence of respiratory failure requiring mechanical ventilation, or (b) the presence of shock; other organ failures that require monitoring and treatment in the ICU. All patients with an established diagnosis of COVID-19 in Egyptian quarantine hospitals at any clinical stage will be included in this study.
Who cannot join
- Patients < 12 years old.
- Pregnant females.
- Patients with renal impairment with creatinine clearance < 30 mL/min.
- Patients with malignancies particularly Hepatocellular Carcinoma (HCC).
- Patients using Favipiravir or Lopinavir-Ritonavir, as the co-administration of these drugs with Sofosbuvir/Ledipasvir has not been studied.
- Patients with decompensated liver cirrhosis (Child-Pugh score B and C).

About this study
Official title: Efficacy of Adding Sofosbuvir/Ledipasvir Combination, or Nitazoxanide to the Standard of Care in Treatment of COVID-19: A Randomized Controlled Trial
The efficacy of treating COVID-19 infection by using Sofosbuvir/Ledipasvir and Nitazoxanide will be examined. Included patients will be into 3 groups. The 1st group will receive Sofosbuvir/Ledipasvir plus the standard care treatment (SCT). The 2nd group will take Nitazoxanide and SCT, while the 3rd group will receive only SCT. Then the clinical improvement and the rate of PCR change from positive to negative will be evaluated in each group.
Read the detailed description
This study is an open-label, randomized, controlled trial. A total of 240 patients who are recruited in 2 quarantine hospitals (15th of May hospital, Cairo, and Al Rajhi hospital, Assiut), will be randomly assigned in a 1:1:1 ratio (80 patient in each treatment arm), to receive either the fixed combination of Sofosbuvir/Ledipasvir (400 mg and 90 mg, orally) once daily for 14 days, plus the standard care treatment regimen (SCT) for COVID-19 patients according to the Egyptian Ministry of Health (MOH) protocol (Group 1), or nitazoxanide (500 mg, orally) four times per day for 14 days, plus STC (Group 2), or SCT alone (Group 3). All treatment groups will be followed up by laboratory investigations and PCR for SARS-CoV-2 virus at the time of enrollment, days 5, 8, 11, and 14. Supportive care comprised, as necessary, supplemental oxygen, noninvasive and invasive ventilation, antibiotic agents, vasopressor support, renal-replacement therapy, and extracorporeal membrane oxygenation (ECMO). To ensure a balanced distribution of case severities in all study groups, randomization will be stratified based on the case severity index issued by WHO (https://www.who.int/docs/default-source/coronaviruse/clinical-management-of-novel-cov.pdf).
Written informed consent will be obtained from all patients or the patient's legal representative if the patient is too unwell to provide consent. The trial will be conducted in accordance with the principles of the Declaration of Helsinki and the Good Clinical Practice guidelines of the International Conference on Harmonisation. The authors are responsible for designing the trial and for compiling and analyzing the data. The authors vouch for data completeness and accuracy and adherence to the trial protocol.

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change of PCR from positive to negative (time frame: 2 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04498936, which also lists 20 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Nov 2020.
