Sorrento and Mount Sinai Health System Enter Into Exclusive License Agreement for Development of Potent Antibody Combinations Aimed at Neutralizing SARS-CoV-2 and the Emerging United Kingdom and South Africa Variants of COVID-19

March 9, 2021 at 9:00 AM EST
  • Sorrento is moving forward with the research and development of COVISHIELD antibody combinations with potentially potent neutralizing activities against early COVID-19 pandemic virus isolates as well as current variants of concern.
  • Pre-clinical development of an antibody combination therapeutic including Sorrento and Mount Sinai antibodies for intravenous (IV) and intranasal administration is underway.
  • This step in the fight against COVID-19 follows the progress made with Sorrento’s intravenous STI-2020 (COVI-AMG™) that completed Phase 1 safety studies in healthy volunteers and is now in Phase 2 studies for mild to moderate COVID-19 patients in outpatient and inpatient settings; and Sorrento’s intranasal STI-2099 (COVIDROPS™) that is being tested in Phase 1 studies in healthy volunteers and mild to moderate COVID-19 patients.

SAN DIEGO, March 09, 2021 (GLOBE NEWSWIRE) -- Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”) today announced major progress in the development of COVISHIELD through the license of intellectual property developed by the scientific team at the Icahn School of Medicine at Mount Sinai (“Mount Sinai”). Sorrento and Mount Sinai have entered into an Exclusive License Agreement for a collection of antibodies having SARS-CoV-2 neutralizing properties that were developed by Mount Sinai.

The license also contemplates Sorrento and Mount Sinai pursuing future collaborations in developing humanized monoclonal antibodies for therapeutic applications.

COVISHIELD, which is under development, will be a combination of two monoclonal antibodies designed to protect against disease caused by existing and emerging variants of SARS-CoV-2. Using the early pandemic variants as well as the emerging variants of concern (“VOCs”) that have increased in prevalence globally through the course of the pandemic, Sorrento identified candidate monoclonal antibody combinations, or “cocktails”, with potent activity against the breadth of these VOCs, including the United Kingdom (B.1.1.7), South Africa (B.1.351), and Japan/Brazil (B.1.128) variants. Positive results from these laboratory studies are expected to support the future research path and FDA evaluation of COVISHIELD.

COVISHIELD represents a coordination of the discovery and development resources of Sorrento, incorporating intellectual property developed by Mount Sinai, in order to provide a rapid and dynamic means of responding to changes in the public health burden posed by coronaviruses and similar pandemic threat pathogens. Sorrento is developing capabilities and solutions with a goal of contributing to pandemic readiness.

Sorrento Chairman and CEO, Dr. Henry Ji, commented, “We are pleased with the excellent COVISHIELD antibody candidates identified thus far, and we at Sorrento are committed to rapidly developing the COVISHIELD cocktail against known and emerging COVID-19 variants of concern. Sorrento looks forward to future collaborations with the respected research capabilities of Mount Sinai centered on the development of innovative anti-viral and anti-cancer therapeutic candidates.”

About Sorrento Therapeutics, Inc.

Sorrento is a clinical stage, antibody-centric, biopharmaceutical company developing new therapies to treat cancers 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 fully human antibodies (“G-MAB™ library”), clinical stage immuno-cellular therapies (“CAR-T”, “DAR-T™”), antibody-drug conjugates (“ADCs”), and clinical stage oncolytic virus (“Seprehvir™”). Sorrento is also developing potential antiviral therapies and vaccines against coronaviruses, including COVIGUARD™, COVI-AMG™, COVISHIELD™, Gene-MAb™, COVI-MSC™ and COVIDROPS™; and diagnostic test solutions, including COVITRACK™, COVISTIX™ and COVITRACE™.

Sorrento's commitment to life-enhancing therapies for patients is also demonstrated by our effort to advance a first-in-class (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 post-herpetic neuralgia. RTX has completed a Phase IB trial for intractable pain associated with cancer and a Phase 1B trial in osteoarthritis patients. SEMDEXA is in a pivotal Phase 3 trial for the treatment of lumbosacral radicular pain, or sciatica. ZTlido® was approved by the FDA on February 28, 2018.
