Medical Herbs Inhibit Inflammation Directing T Cells to Kill the COVID-19 Virus (COVID)
The Trial Uses Medicinal Herbs to Direct T Cells to Engulf the COVID-19 Virus and Protect the Organs Well
Medical Herbs Inhibit Inflammation Directing T Cells to Kill the COVID-19 Virus (COVID) (NCT04790240) is a Phase 1 / Phase 2 interventional studying Covid19 Virus Infection, sponsored by All Natural Medicine Clinic, LLC. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
The human immune system is designed to protect individuals from external sources of infection and internal cell mutation. It works effectively and efficiently until inflammation disturbs its functioning. Once compromised by inflammation, the immune system loses its capacity to recognize antigens and dependably defend the body against disease and illness. When COVID-19 invades humans, it causes an immune-storm (cytokine-storm) that can directly damage the organ(s), leading to death. The virus is an antigen - a trigger - but it is not the actual reason that causes organ failure and death; instead, it is the body's over immune reaction that is the cause. In attempting to protect the body, the immune system overreacts to the antigen, which includes the infected cells, which causes a cytokine-storm, and the subsequent and rapid shut down of the infected individual's organ(s)' structure, leaving the body without sufficient strength or time to fight back. When the medical herbs join the body, it can slow down the immune reaction. Medical herbs benefit the physical body; they protect the cells and organism structure and mediate the immune response, allowing the T cells to kill the virus (mutated or not) internally. Such success has been achieved by the All Natural Medicine Clinic during pre-clinical trials. This clinical study's goal is to demonstrate that the immune system can be rebuilt and retrained, using natural medicine (i.e., medical herbs), to kill the virus without causing the immune storm, and to explore the mechanism by which these medical herbs, which have been used for thousands of years for healing, achieve results.
What Stage of Research Is This?
Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Covid19 Virus Infection, a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
Target enrollment of 100 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Covid19 Virus Infection subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.
