Sorrento to Present Data Demonstrating STI-2020 Preserves Binding Against UK B.1.1.7 SARS-CoV-2 Mutated Spike Protein

January 19, 2021 at 5:05 PM EST

SAN DIEGO, Jan. 19, 2021 (GLOBE NEWSWIRE) — Sorrento Therapeutics, Inc. (Nasdaq: SRNE, “Sorrento”), announced that it will be presenting preliminary results from an ongoing SARS-CoV-2 mutation surveillance program for its neutralizing antibodies currently in clinical and pre-clinical development for treatment of patients with COVID-19 disease.

Dr. Robert Allen, Senior Vice President, Antiviral and Oncolytic Immunotherapy Development at Sorrento and Chief Scientific Officer of SmartPharm Therapeutics, will be presenting data from the SARS-CoV-2 Spike protein variant screening program at PepTalk 2021 today and on Thursday of this week.

Disclosed data will provide evidence of maintained binding potency by STI-2020 in in vitro assays including the Spike amino acid changes found in SARS-CoV-2 viruses of the B.1.1.7 lineage initially identified in the United Kingdom which has since been detected in ten U.S states. This is highly clinically relevant as it might signify that the STI-2020 antibody currently in clinical trials is not anticipated to behave differently against the new virus variant predicted by the CDC to potentially become the dominant virus variant infecting people in the US as early as March 2021.

Sorrento will also provide early in vitro results of diminished STI-2020 binding potency in assays including Spike proteins derived from viruses of the B.1.351 lineage first identified in South Africa, but yet undetected in the United States.

Additional neutralizing antibodies were identified that bind strongly to the B.1.1.7 and B.1.351 spike proteins and are under further analyses for neutralization activities both in vitro and in vivo. Upon further validation, the most promising antibody clones will be selected as potential candidates to be added as components of our COVI-SHIELD antibody cocktail as dictated by the continued emergence of mutations in clinical isolates. Sorrento believes it has in place highly potent antibodies against the most recent UK and South Africa viral variants for inclusion in COVI-SHIELD-2021.

About Sorrento Therapeutics, Inc. 

Sorrento is a clinical stage, antibody-centric, biopharmaceutical company developing new therapies to treat cancers. 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 (“ADC”), and clinical stage oncolytic virus (“Seprehvir®”).  Sorrento is also developing potential antiviral therapies and vaccines against coronaviruses, including COVI-GUARD™, COVI-AMG™, COVI-SHIELD™, Gene-MAb™, COVI-MSC™ and COVI-DROPS™; and diagnostic test solutions, including COVI-TRACK™, COVI-STIX™ and COVI-TRACE™.

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.
