COVID-19 Clinical Trial
Official title:
Clinical Assessment of Oral Lactoferrin as a Safe Antiviral and Immunoregulatory Therapy in Patients Diagnosed With COVID-19 Disease
The aim of the study is to clinically use bovine Lf as a safe antiviral adjuvant for treatment and to assess the potential in reducing mortality and morbidity rates in COVID-19 patients. The study was approved by the ethical committee of the Egyptian Center for Research and Regenerative Medicine in 11-5-2020.
The World Health Organization (WHO) declared the coronavirus (SARS-CoV-2, COVID-19) outbreak a Public Health Emergency of International Concern with a pandemic spread. The situation is rapidly evolving, which raises the approach of reproposing already approved drugs to meet the emerging challenge and to save time and money. Lactoferrin (Lf) is a natural glycoprotein that broadly distributed within the body fluids and found predominantly in milk. It represents a known component of the innate immune system. The antiviral activity of Lf has been reported against many viruses, including SARS-CoV-1, through blocking the viral receptors on the host cells preventing them from entry and replication. Markedly, data reveals that Lf interacts with Heparan Sulfate Proteoglycans (HSPGs) and Angiotensin Converting Enzyme 2 (ACE2) receptors that are reported as SARS-CoV-2-binding sites to enter the host cell, suggesting a potential significance of Lf as an antiviral against SARS-CoV-2. Moreover, the immunoregulatory effects of Lf can protect against the cytokine-storm and thrombotic complications that result from the COVID-19-induced over-stimulated inflammatory response and exaggerated immune reactions. In addition, Lf can decrease the free iron toxicity caused by the virus as it has a strong iron chelating ability. Lf is a safe approved food supplement that is available in the markets for enhancement of immunity and for treatment of anemia. The aim of this study is to perform a randomized, double-blind, placebo-controlled, two arms, clinical trial to assess oral enteric-coated tablet of bovine apolactoferrin (the low iron-content form of Lf) as a safe antiviral and immunoregulatory therapy in patients diagnosed with COVID-19 disease. ;
