Adamis Provides Update on the Phase 2/3 Trial of Tempol in COVID-19 Positive High-Risk Subjects

  • Interim data from the Phase 2/3 clinical trial of Tempol did not demonstrate statistical significance of its primary endpoint of clinical resolution of COVID-19 symptoms at day 14 versus placebo
  • Independent Data Safety Monitoring Board recommends halting the trial

SAN DIEGO, Sept. 21, 2022 (GLOBE NEWSWIRE) -- Adamis Pharmaceuticals Corporation (NASDAQ: ADMP) today announced that the third planned interim analysis of the Phase 2/3 clinical trial examining the effects of Tempol in high risk subjects with early COVID-19 infection did not achieve its primary endpoint, as measured by comparing the rate of sustained clinical resolution of symptoms of COVID-19 at day 14 of Tempol versus placebo. The independent Data Safety Monitoring Board (DSMB) recommended that the study be halted early due to lack of efficacy. The DSMB did note that no safety concerns were identified in the subjects that received Tempol. Based on the recommendation from the DSMB, the Company has halted the trial and will now evaluate the unblinded data from the trial to determine the next developmental steps for Tempol.

“We are obviously disappointed that the study did not meet its endpoints,” said Ron Moss, MD, Chief Medical Officer of Adamis. “Much of the preclinical work on Tempol for COVID-19 examined the effects of the drug on severe illness. This trial did not meet its primary endpoint, but we are exploring the possibility that vaccinations and the less virulent variants (Omicron) during the trial period may have obscured an effect of Tempol. This speculation is based on the lower-than-expected observed hospitalization rate in this trial (less than 1%) compared to other COVID-19 treatment trials. We will continue to analyze the data to determine if we believe Tempol can be utilized in other COVID patient populations including those with more severe illness or immunocompromised. I would like to thank our clinical research partners, the trial investigators and all the trial subjects for their participation.”

David J. Marguglio, Adamis’ CEO added, “Though we are certainly frustrated with these results, we remain bullish on ZIMHI® (launched in 2022) and SYMJEPI® and our team is focused on increasing sales and improving manufacturing efficiencies for our commercial products.”

Phase 2/3 Trial

The trial “A Phase 2/3, Adaptive, Randomized, Double-Blind, Placebo-Controlled Study to Examine the Effects of Tempol (MBM-02) in Subjects With COVID-19 Infection” was designed to enroll approximately 248 high risk subjects with early COVID-19 infection age 18 years of age and older. Eligible subjects with positive COVID-19 infection within five days of study entry plus at least one co-morbidity were randomized one-to-one to receive either Tempol or placebo. Co-morbidities include age of 65 or older, hypertension, diabetes, obesity, cancer, immunodeficiency and in the opinion of the investigator the risk factor is not acutely life-threatening. Patients randomized to Tempol received 800mg daily in two divided oral doses of 400mg capsules for up to 21 days. Similarly, placebo capsules were administered twice daily to subjects in the placebo group for up to 21 days.
