First Wave BioPharma Completes Enrollment for Part 2 of RESERVOIR Phase 2 Trial Evaluating FW-COV in COVID-19-Related GI Infections
No Drug-Related SAEs Reported; Topline Data Expected 1H 2022
Part 2 of RESERVOIR Trial to Evaluate Efficacy of FW-COV, an Oral Formulation of Niclosamide, and Expand Safety Observations on 150 Trial Participants
BOCA RATON, Fla., Jan. 06, 2022 (GLOBE NEWSWIRE) -- First Wave BioPharma, Inc., (NASDAQ:FWBI), (“First Wave BioPharma” or the “Company”), a clinical-stage biopharmaceutical company specializing in the development of targeted, non-systemic therapies for gastrointestinal (GI) diseases, today announced that it has completed enrollment for Part 2 of the RESERVOIR Phase 2 trial evaluating FW-COV as an outpatient treatment for COVID-19-related gastrointestinal (GI) infections. FW-COV is a proprietary, oral, tablet formulation of micronized niclosamide being developed to remove SARS-CoV-2 (SARS2), the virus that causes COVID-19, from the GI tract.
RESERVOIR is designed as a two-part, two-arm, randomized, placebo-controlled Phase 2 study with a primary purpose to confirm the safety of FW-COV and assess the drug’s ability to remove the SARS-CoV-2 (SARS2) virus from the digestive tract. The 150 patients successfully enrolled in Part 2 of the trial were randomized to receive either FW-COV or a placebo treatment for 14 days and will be observed for six weeks following the end of treatment. No FW-COV drug-related serious adverse events (SAEs) have been reported from the trial participants. First Wave BioPharma expects to report top-line data in the first half of 2022.
“We are very pleased to complete enrollment of the second part of the RESERVOIR trial and look forward to reporting top-line data in the coming months,” stated James Sapirstein, President and CEO of First Wave BioPharma. “This is an important milestone for First Wave and the development of FW-COV. Based on the positive safety data observed thus far, combined with earlier published in vitro COVID efficacy data1 for niclosamide, we believe that FW-COV has the potential to contribute to the global need for new therapies against SARS2. Furthermore, because niclosamide targets the entire virus, and not just the spike protein, we believe that FW-COV may prove effective against multiple strains of COVID-19, including the Delta and Omicron variants. If RESERVOIR is successful and supported by additional data, we anticipate being in a position to submit an Emergency Use Authorization (EUA) application later this year.”
James Pennington, M.D., Chief Medical Officer of First Wave BioPharma, commented, “Safety data thus far indicates that our micronized oral niclosamide therapy is well tolerated, and we believe that further data will demonstrate that FW-COV can add a much-needed new oral anti-viral therapy to the COVID-19 treatment regimen. Millions of patients around the world already suffer complications from COVID-19, and millions more could face similar medical issues as the Omicron variant continues to fuel a surge in new infections.”
About COVID-19 Gastrointestinal Infections
Gastrointestinal infection symptoms (severe diarrhea, vomiting and abdominal pain) have been reported in approximately 18% of COVID-19 cases.2 Of the 57 million individuals who are reported to have contracted COVID-19 in the U.S.,3 this would translate into approximately 10 million patients having GI infection. Of the 295 million cases reported globally,3 it would translate into almost 53 million patients. Furthermore, approximately 10% of patients who were infected with COVID have persistent symptoms months after their initial diagnosis.4 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.5 There is some evidence to support the view that the GI tract is a possible reservoir6 for persistence 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.1 Additionally, emerging evidence confirms the severe GI-related complications of COVID and potential fecal spread of the virus.6 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-COV is a niclosamide based small molecule 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-COV 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-COV 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
About First Wave BioPharma, Inc.
First Wave BioPharma is a clinical-stage biopharmaceutical company specializing in the development of targeted, non-systemic therapies for gastrointestinal (GI) diseases. First Wave BioPharma is currently advancing a therapeutic development pipeline populated with multiple clinical stage programs built around its two proprietary technologies – niclosamide, an oral small molecule with anti-viral and anti-inflammatory properties, and the biologic adrulipase, a recombinant lipase enzyme designed to enable the digestion of fats and other nutrients. The Company’s niclosamide portfolio is led by two clinical programs in Phase 2 clinical trials: FW-COV, for COVID-19 gastrointestinal infections and FW-UP, for ulcerative proctitis (UP) and ulcerative proctosigmoiditis. Three additional indications of niclosamide, FW-ICI-AC, for Grade 1 and Grade 2 Immune Checkpoint Inhibitor-associated colitis and diarrhea in advanced oncology patients, FW-UC (ulcerative colitis) and FW-CD (Crohn’s disease) are expected to enter the clinic in 2022 and 2023. First Wave BioPharma is also advancing FW-EPI (adrulipase) for the treatment of exocrine pancreatic insufficiency (EPI) in patients with cystic fibrosis and chronic pancreatitis.
