Adamis Pharmaceuticals Announces Tempol Reduces Lung Inflammation in the COVID-19 Challenged Hamster Model

SAN DIEGO, March 15, 2021 — Adamis Pharmaceuticals Corporation (Nasdaq: ADMP) (“Company”) announced today that in studies conducted at Galveston National Laboratory (GNL), University of Texas Medical Branch (UTMB) at Galveston, hamsters challenged with the virus that causes COVID-19 (SARS-CoV-2), resulted in decreased inflammation in the lungs of animals treated with Tempol compared to controls. This is the first data demonstrating that Tempol, a novel antioxidant, can reduce inflammation in animals given the virus (SARS-CoV-2) that causes COVID-19. The group plans on submitting the publication to a peer review journal.

Dr. Chien-Te Kent Tseng, Professor of the Department of Microbiology and Immunology and Director of GNL’s SARS/MERS/COVID-19 Laboratory at UTMB, commented on these results: “In our hamster COVID-19 model, pulmonary inflammation with cellular infiltrates and hemorrhage (mild-to-moderate) is triggered by SARS-CoV-2 infection. Treatment with Tempol reduces the overall inflammatory responses and appears to start repairing damaged lungs.”

These results are also consistent with the results that the Company announced regarding in-vitro cytokine data from Stanford University. The results demonstrated that incubation of Tempol significantly suppresses multiple inflammatory cytokines from cells taken from COVID-19 patients.

Tempol has demonstrated both potent anti-inflammatory, anticoagulant, and antioxidant activity. Both inflammatory cytokines and reactive oxygen species (ROS) from cells of the immune system called macrophages and neutrophils damage the lung in Acute Respiratory Distress Syndrome (ARDS). Tempol has now been shown to: (1) Decrease the proinflammatory cytokines (cytokine storm) in animal models (lipopolysaccharide induced), (2) Suppress cytokines in stimulated COVID-19 positive human cells, and (3) Reduce inflammation in hamsters challenged with COVID-19. In addition, Tempol has been shown to decrease platelet aggregation, a problem observed in many COVID-19 patients.

The new results demonstrating decreased lung inflammation in hamsters challenged and treated with Tempol are consistent with the design of the recent FDA allowed IND and protocol to study Tempol in early COVID-19 infection. The goal of the study titled, “A Phase 2/3, Adaptive, Randomized, Double-Blind, Placebo-Controlled Study to Examine the Effects of Tempol (MBM-02) on Preventing COVID-19 Related Hospitalization in Subjects with COVID-19 Infection” is to examine the safety and activity of Tempol in COVID-19 patients early in the infection. In addition to safety, the study will examine markers of inflammation and the rate of hospitalization for patients taking Tempol versus placebo early in COVID-19 infection. More details of the protocol can be found here or by searching Dr. Ronald Moss, Chief Medical Officer of Adamis, commented: “These results from a validated animal model for COVID-19 provide further support on implementing our well-designed clinical trial in order to obtain activity and safety information on the use of Tempol in early COVID-19 infection in humans.”

Dr. Dennis J. Carlo, President and Chief Executive Officer of Adamis Pharmaceuticals, commented: “The results to date support the design of our clinical study in that we are targeting early infection with the objective of reducing lung inflammation and eventual hospitalization. We are hopeful that the clinical study will replicate the results obtained to date, i.e., preventing or ameliorating some of the most severe symptoms of COVID-19 caused by dysfunctional inflammation.”

In addition to Dr. Tseng, the UTMB team includes Drs. Aleksandra K. Drelich, Kempaiah Rayavara Kempaiah, and Bi-Hung Peng (Pathologist).
