Sorrento Therapeutics, Inc. announces a $4.6 Million U.S. Government contract from the NIAID for a Sensitive, Reusable, and Rapid Diagnostic Platform for Pandemic Preparedness

SAN DIEGO, June 13, 2023 (GLOBE NEWSWIRE) — Sorrento Therapeutics, Inc. (OTC: SRNEQ, “Sorrento”) today announces it has been awarded a $4.6 million contract from the National Institute of Allergy and Infectious Diseases, a part of the National Institutes of Health (NIH) for the development of in vitro diagnostics for biodefense, antimicrobial resistant infections and emerging infectious diseases. The award shows NIAID’s support for the development of promising quantitative diagnostics technologies for detection of signatures from biothreat pathogens as well as pathogens causing emerging or reemerging infectious diseases, and for pandemic preparedness.

The purpose of the contract is to develop a diagnostic platform for rapid and sensitive detection of proteins and other biomolecules that improves existing rapid testing devices (RTDs). Current diagnostic RTDs have long development timelines and low clinical sensitivity. Sorrento and Virex Health, LLC (Virex Health), a wholly owned subsidiary of Sorrento, plan to develop an adaptable diagnostic platform which is highly sensitive and cost-effective for multiple pathogens. This approach leverages the expertise of Sorrento to rapidly select and produce highly specific antibodies from its proprietary G-MAB™ library targeting viral and bacterial antigens, combined with a chemical detection approach and the existing infrastructure of the glucometer industry.

Virex Health has developed a proprietary technology for electrochemical detection of bioanalytes (virus, proteins, and small molecules) using the similar electronic device requirements employed in reusable glucometers and has reformulated the chemistry contained on the test strip to detect pathogens. In so doing, Virex Health leverages an existing infrastructure that produces tens of millions of devices per year. The objective is to address the needs of rapid detection for biodefense and new emerging infectious disease preparedness. At the conclusion of the contract, Sorrento and Virex Health intend to deliver a rapid, sensitive, accurate and scalable diagnostic capable of being readily deployed in response to an emergent or reemergent threat. “Once the diagnostic platform is developed, our unique approach can be quickly transferred to other pathogens and deployed when needed on a large scale,” said Scott Schaus, Ph.D., Co-founder and Chief Technology Officer for Virex Health.

“We are pleased to accept this award and collaboration with the U.S. Government to ensure that, as a society, we are better prepared for the next pandemic. This award validates our unique approach of combining antibody development and electrochemical-based diagnostics for a rapid response to save lives and manage infectious disease outbreaks,” stated Henry Ji, Ph.D., Chairman and CEO of Sorrento.

“This project has been funded in whole or in part with Federal funds from the National Institute of Allergy and Infectious Diseases, National Institutes of Health, Department of Health and Human Services, under Contract No. 75N93023C00024”.

About Sorrento Therapeutics, Inc.

Sorrento is a clinical and commercial stage biopharmaceutical company developing new therapies to treat cancer, pain (non-opioid treatments), autoimmune disease and COVID-19. Sorrento’s multimodal, multipronged approach to fighting cancer is made possible by its extensive immuno-oncology platforms, including key assets such as next-generation tyrosine kinase inhibitors (“TKIs”), fully human antibodies (“G-MAB™ library”), immuno-cellular therapies (“DAR-T™”), antibody-drug conjugates (“ADCs”), and oncolytic virus (“Seprehvec™”). Sorrento is also developing potential antiviral therapies and vaccines against coronaviruses, including STI-1558 and COVI-MSC™, and diagnostic test solutions, including COVIMARK.

Sorrento’s commitment to life-enhancing therapies for patients is also demonstrated by our effort to advance a TRPV1 agonist, non-opioid pain management small molecule, resiniferatoxin (“RTX”), and SP-102 (10 mg, dexamethasone sodium phosphate viscous gel) (SEMDEXA™), a novel, viscous gel formulation of a widely used corticosteroid for epidural injections to treat lumbosacral radicular pain, or sciatica, and to commercialize ZTlido® (lidocaine topical system) 1.8% for the treatment of postherpetic neuralgia (PHN). RTX has been cleared for a Phase II trial for intractable pain associated with cancer and a Phase II trial in osteoarthritis patients. Positive final results from the Phase III Pivotal Trial C.L.E.A.R. Program for SEMDEXA™, its novel, non-opioid product for the treatment of lumbosacral radicular pain (sciatica), were announced in March 2022. ZTlido® was approved by the FDA on February 28, 2018.
