Nitazoxanide (NT-300) Trial Comes to Northern Alabama as Cullman Clinical Trials Launches COVID-19 Targeting Study

Another antiparasitic drug has emerged as a potential treatment for COVID-19, and trial site organization in Cullman, Alabama, called Cullman Clinical Trials, will be conducting a study to determine if this repurposed drug can be used to fight the coronavirus. This research site seeks 800 participants to test nitazoxanide and its potential to treat COVID-19. Cullman Clinical Trials is affiliated with Cullman Primary Care, and this relationship assures access to more patients than the typical independent trial site organization. Can a repurposed antiparasitic, rebranded as NT-300, reduce the impact of COVID-19? A Northern Alabama research site partners with sponsor Romark Laboratories to find out.

What is Nitazoxanide?

Produced by Romark Laboratories, this antiparasitic drug has been found to inhibit a broad range of respiratory pathogens in cell cultures, and this includes SARS-CoV-2, the virus behind COVID-19. Nitazoxanide was approved by the U.S. Food and Drug Administration (FDA) by 2002 as a treatment for diarrhea caused by the water-borne parasitic infection Cryptosporidium under the trade name Alinia.®

By April, Romark Laboratories announced the intention to test its new drug candidate, NT-300, based on the FDA approved drug nitazoxanide, against COVID-19 and other viral respiratory illnesses in high-risk populations, including elderly residents of long-term care facilities and healthcare workers.

The company uncovered that in cell cultures, the active ingredient in NT-300 (nitazoxanide) inhibits the replication of a broad range of respiratory viruses, including SARS-CoV-2. Interestingly, this is similar to another FDA approved antiparasitic drug, ivermectin.

Nitazoxanide has been shown to inhibit the replication of SARS, MERS, and other coronaviruses as well as influenza viruses, rhinoviruses, parainfluenza viruses, RSV, and others in cell culture studies. This substance’s broad-spectrum antiviral activity is based on its ability to interfere with human cellular pathways that viruses are known to exploit for replication, rather than to a virus-targeted mechanism.

For any safety issues, see the FDA label.

Clinical Trials Involving NT-300

Presently, Romark is sponsoring three clinical trials involving NT-300, including NCT04486313, NCT04359680, and NCT04343248. There are several other trials around the world involving generic Nitazoxanide targeting COVID-19.

Cullman Alabama Study

Cullman Clinical Trials is participating in NCT04486313. The recent report from the local press Cullman Times mentioned that the study drug is administered for five (5) days. This is the only one of the studies that includes that same regimen protocol. 

Officially titled Phase 3, Randomized, Double-Blind, Placebo-Controlled, Trial to Evaluate Efficacy and Safety of Nitazoxanide in the Treatment of Mild or Moderate COVID-19,” the Phase 3, multicenter study involves a target of 800 patients. The study started in August 2020 and runs till October 30, 2020. Patients will be given two nitazoxanide 300 mg tablets twice daily for five days, and Vitamin Super B-Complex administered orally twice daily to maintain the blind. 

The study’s primary outcome measure includes time (up to 21 days) to evaluate the study drug’s effect in reducing the time to sustained response compared to placebo in subjects with mild to moderate COVID-19. The secondary outcome measure involves the time (up to 21 days) to reduce the progression rate to severe COVID-19 illness compared to placebo.

As reported in another press release, Cullman Clinical Studies is affiliated with Cullman Primary Care, and those people who go to Cullman Primary Care with COVID-19 symptoms and meet the clinical trial’s criteria will be asked if they want to take part in the study to test the efficacy of the drug.

According to Clinicaltrials.gov, the sponsor is using clinical research services provider Celerion.
