Adamis Pharmaceuticals Doses First Patients in Phase 2/3 Clinical Trial for Tempol in the Treatment of COVID-19
Adamis Pharmaceuticals Corporation recently announced the initiation of patient dosing in the Phase 2/3 clinical trial for Tempol, an oral antiviral product candidate, in adult patients with confirmed COVID-19 infection. In preclinical studies, Tempol has been shown to have antiviral, anti-inflammatory and antioxidant activity. The trial is designed to enroll 248 patients.
Shyam Kottilil, MBBS, PhD, Professor of Medicine at the University of Maryland School of Medicine (UMSOM), Chief of the Division of Clinical Care and Research at UMSOM’s Institute of Human Virology, and Principal Investigator for the trial, said “The timing for this trial could not be more important as the delta variant spreads and breakthrough infections in vaccinated individuals occur in the US and worldwide. Tempol as an oral antiviral and anti-inflammatory may be an important countermeasure if proven safe and effective in this trial.”
Dr. Dennis J. Carlo, President and Chief Executive Officer of Adamis, added “We are pleased to begin patient dosing in this Phase 2/3 clinical trial for Tempol, which has demonstrated highly encouraging preclinical data in several disease models of infection and inflammation. Worldwide appearance of new variants with increased transmissibility and resistance necessitates the development of new therapeutic agents. The data from Israel should be a wake-up call to the US and the rest of the world. Israel has among the highest levels of vaccination for COVID-19, yet the country is now showing one of the world’s highest infection rates (breakthrough). Currently, in Israel, the majority of the hospitalized patients are fully gene vaccinated. If approved, Tempol may not only prove to be a very important drug for the treatment of COVID-19, but it may also play a role in curbing the pandemic.”
Recently, the National Institutes of Health (NIH) highlighted Tempol as a potential home treatment for COVID-19 (NIH Study) The NIH news stated that, “This treatment would likely prevent severe disease.” Recent studies conducted by NIH researchers suggested that Tempol had potent antiviral activity against the virus that causes COVID-19 in laboratory studies. The NIH news article further describes how Tempol could possibly reduce COVID-19 symptoms by calming inflammation, protecting organs from damage, and decreasing the clumping of platelets.
The company recently announced (Stanford Study) the results of a published study in collaboration with Stanford University researchers suggesting that Tempol has strong, broad in-vitro anti-cytokine activity. Suppression of inflammatory cytokines with an antioxidant may be a beneficial treatment strategy in early COVID-19 infection.
This Phase 2/3 adaptive, randomized, double-blind, placebo-controlled clinical trial is designed to enroll approximately 248 high risk unvaccinated subjects with early COVID-19 infection age 18 years of age and older. The primary endpoint is the rate of hospitalization for patients receiving Tempol, versus those receiving placebo. Eligible subjects with positive COVID-19 infection within 5 days of study entry plus at least one co-morbidity will be randomized 1:1 to receive either Tempol or placebo. Co-morbidities include hypertension, diabetes, obesity, cancer, chronic renal disease, and immunodeficiency, and in the opinion of the investigator, the co-morbidity is not acutely life threatening. Patients randomized to Tempol (n=124), will receive 800 mg daily in two divided doses of 400 mg for up to 21 days. Similarly, placebo capsules will be administered twice daily to subjects in the placebo group (n=124) for up to 21 days.
As part of the initial Phase 2 portion of the study, 50 COVID positive subjects will be enrolled and randomized 1:1 to receive either Tempol or placebo. An interim analysis by the data and safety monitoring board (DSMB) will examine safety and markers of systemic inflammation during a Stage 1 interim analysis. Based on the DSMB analysis, the Phase 3 portion of the trial designed to enroll 198 patients may begin, with a second interim analysis planned after enrollment of 124 patients. A thorough safety assessment will be conducted, and all treatment related adverse events will be recorded, evaluated and compared for the treated and placebo groups.
