Phase 2 placebo-controlled clinical trial to confirm safety of FW-1022 and investigate its ability to remove SARS-CoV-2 virus from the GI tract
BOCA RATON, Fla., Sept. 10, 2021 (GLOBE NEWSWIRE) -- AzurRx BioPharma, Inc. (“AzurRx” or the “Company”) (NASDAQ: AZRX), a company specializing in the development of targeted non-systemic, therapies for gastrointestinal (GI) diseases, today announced the activation of seven (7) new clinical trial sites in India for the ongoing RESERVOIR trial evaluating FW-1022. FW-1022 is a proprietary oral tablet formulation of micronized niclosamide developed for the treatment of COVID-19-related GI infections.
The seven new clinical trial sites in India, together with the existing eleven sites in the U.S. and the five trial sites recently added in the Ukraine, brings the total number of RESERVOIR trial sites to twenty-three. AzurRx expects to report topline results during the first quarter of 2022.
“Expanding our clinical trial into India provides access to the second most populous country in the world and one that, unfortunately, continues to experience a devastating COVID-19 outbreak,” said James Sapirstein, President and CEO of AzurRx BioPharma. “Despite the global vaccination effort, COVID-19, and the new Delta variant, remain pernicious. Infection rates in India average 38,000 a day with more than 31.1 million people infected overall. The virus’ impact on the GI tract is often overshadowed by its effect on the respiratory system, however COVID-19-related GI infection remains an undertreated symptom with devastating aftereffects. A safe and effective treatment that removes the virus from the gut is needed for the millions who have contracted and continue to fall victim to the virus.”
The RESERVOIR clinical trial is designed as a two-part, two-arm, placebo-controlled Phase 2 study. The trial’s primary objectives are to confirm the safety of FW-1022 in the treatment of patients with COVID-19-related GI infections and to evaluate its efficacy in clearing SARS-CoV-2, the virus that causes COVID-19, from the GI tract. The primary efficacy measure of the RESERVOIR trial is the rate of fecal SARS-CoV-2 clearance (stool sample) assessed by RT-PCR, comparing the niclosamide arm to the placebo arm for up to six weeks. These long-term observation data could indicate that niclosamide treatment has the potential to improve “long haul” COVID-19 symptoms. Topline data from the study are anticipated during the first quarter of 2022.
About COVID-19 Gastrointestinal Infections
Gastrointestinal infection symptoms (severe diarrhea, vomiting and abdominal pain) have been reported in approximately 18% of COVID-19 cases.1 Of the 40 million individuals who are reported to have contracted COVID-19 in the U.S.,2 this would translate into over 7 million patients having GI infection. Of the 220 million cases reported globally,3 it would translate into almost 40 million patients. Furthermore, approximately 10% of patients who were infected with COVID have persistent symptoms months after their initial diagnosis.3 Approximately 86% of these COVID “long haulers” are reported to have GI infection symptoms, with 60% continuing to have diarrhea months after their initial infection.4
There is some evidence to support the view that the GI tract is a possible reservoir for recurrence and fecal spread of the COVID-19 virus as ACE-2, the entry receptor for COVID-19, is highly expressed on GI cells. There currently is no targeted treatment for COVID GI infections.
Niclosamide is a prescription small molecule drug listed as an essential medicine by the World Health Organization (WHO). Niclosamide has been safely used on millions of patients for other clinical indications. In the U.S., niclosamide was approved by the U.S. Food and Drug Administration (FDA) in 1982 for the treatment of intestinal tapeworm infections. In addition to its antihelminthic activity, niclosamide has demonstrated anti-inflammatory and anti-viral properties.
There remains an urgent need to develop new medicines that can be manufactured at large scale quickly to treat COVID-19. Niclosamide was recently identified by the Institut Pasteur Korea as a potent inhibitor of SARS-CoV-2, the virus causing COVID-19, with potency 40X greater than remdesivir.5 Additionally, emerging evidence confirms the severe GI-related complications of COVID and potential fecal spread of the virus. The Company’s clinical trials may establish that patients treated with an oral and non-systemic niclosamide formulation that delivers high local GI concentrations have decreased viral load and GI-associated symptoms of COVID. Importantly, the manufacturing process for niclosamide can be scaled up to supply large populations quickly.
FW-1022 is a niclosamide based small molecule drug which the Company’s clinical trials may establish has anti-viral activity that is effective for the treatment of SARS-CoV-2 (COVID-19) gastrointestinal infections. FW-1022 is anticipated to be supplied as an oral immediate release tablet. The formulation to be used has been milled (micronized) to allow superior dissolution in the gut fluids. This in turn may allow local niclosamide concentrations to reach anti-viral levels. Thus, FW-1022 has the potential to benefit COVID patients by decreasing viral load in the GI tract, treating infection symptoms and preventing transmission of the virus through fecal spread.
