Sorrento Exercises Exclusive Option Agreement With Texas A&M University for MPRO Inhibitors Against Sars-Cov-2 and all Variants of Concern

Written by Customer Service on . Posted in Public Companies.

  • Exclusive license for MPro inhibitors supports rapidly growing small molecule development portfolio for combating COVID-19.
  • Lead compound, MPI8, exhibited potent in vitro antiviral activity against SARS-CoV-2 and all of the major Variants of Concern (VoCs) (alpha, beta, delta and gamma).
  • MPI8 also demonstrated superior antiviral activity in a head-to-head comparison with a late-stage clinical antiviral compound (EIDD-2801).
  • Based on the IC50 data of the Plague Reduction Neutralization Test (PRNT) of live virus infecting Vero E6 cells, MPI8 demonstrated approximately ten-fold (10x) higher antiviral potency than EIDD-2801 against SARS-CoV-2 and its Alpha (UK) and Delta (Indian) VoCs and three to seven-fold (3-7x) higher antiviral potency against Beta (South Africa, 3X) and Gamma (Brazil/Japan, 6-7X) VoCs.

SAN DIEGO, Aug. 26, 2021 (GLOBE NEWSWIRE) — Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”) announced today that it has notified The Texas A&M University System (“TAMUS”) of its exercise of the option to an exclusive license for the global development and commercialization of highly potent main protease (MPro) inhibitors against SARS-CoV-2 and all current and emerging variants of concern (VOCs). Sorrento and TAMUS previously announced the signing of the option agreement on August 24th and 25th, respectively:

Sorrento’s decision to immediately exercise its option is based on very promising preclinical data for the lead compound, MPI8, that shows highly potent broad-spectrum antiviral activity against SARS-CoV-2 and all of the major Variants of Concern (VoCs) (alpha, beta, delta and gamma). Based on initial in vitro data, MPI8 demonstrated superior antiviral activity in a head-to-head comparison with a current Phase 3 investigational oral antiviral agent (EIDD2801). Based on the IC50 data of the Plague Reduction Neutralization Test (PRNT) of live virus infecting Vero E6 cells, MPI8 demonstrated approximately ten-fold (10x) higher antiviral potency than EIDD-2801 against SARS-CoV-2 and its Alpha (UK) and Delta (Indian) VoCs and three to seven-fold (3-7x) higher antiviral potency against Beta (South Africa, 3X) and Gamma (Brazil/Japan, 6-7X) VoCs.

Sorrento expects to complete additional preclinical studies in the coming weeks, including a head-to-head comparison against other late-stage clinical candidates, and will publish its preliminary findings in a pre-print publication.

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 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 Abivertinib, COVIGUARD™, COVI-AMG™, COVISHIELD™, 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.
