Sorrento Announces Dosing of COVID-19 Patients in Phase 2 Clinical Trial for COVIDROPS, a Highly Potent Neutralizing Antibody Against SARS-CoV-2 Including Delta and Alpha Variants of Concern, in an At-Home Outpatient Setting in United Kingdom

  • COVID-19 patients with newly diagnosed SARS-CoV-2 infections were treated in this large Phase 2 efficacy trial in the United Kingdom.
  • COVIDROPS™ neutralizing antibody is administered by intranasal instillation.
  • COVIDROPS is highly active against the original SARS-CoV-2 virus, as well as the India/Delta and UK/Alpha variants currently prevalent in the UK and US.

SAN DIEGO, CA, USA I July 21, 2021 I Sorrento Therapeutics, Inc. (Nasdaq: SRNE, "Sorrento") today announced that COVID-19 patients have been dosed in its Phase 2 efficacy trial. Approximately 350 outpatients with COVID-19 who are asymptomatic or have mild symptoms will be enrolled in this large double-blind, randomized clinical trial evaluating COVIDROPS doses of 10 mg or 20 mg against placebo (details can be found on using the identifier NCT04900428). This study uses a novel decentralized design where subjects are assessed and treated in their homes and received a rapid review and clearance from the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK.

A previously completed safety study conducted in the US at doses up to 60 mg in healthy subjects showed a comparable safety profile to placebo with all reported adverse effects being mild in severity. The UK study will complement Phase 2 trials currently being started in the US and should the results of these studies demonstrate that COVIDROPS is both safe and effective against SARS-CoV-2, Sorrento will apply for Emergency Use Authorization in the US, UK, Canada, India, Mexico and European Union as well as other territories.

COVIDROPS is administered as a simple intranasal instillation into each nostril to recently infected subjects. The neutralizing antibody drug substance is the same antibody as in COVI-AMG, which is a high potency/low dose IV push injection. The antibody is active in vitro and in animal models of COVID-19 infection against the SARS-CoV-2 variants of concern (VoCs) currently infecting the UK and the US, including the highly transmissible and virulent India/Delta variant, as well as the UK/Alpha variant and the original SARS-CoV-2 virus. Sorrento is developing a second neutralizing antibody with potential activity against all VoCs, including the Beta (South Africa) and Gamma (Brazil), for entry into the clinic and is intended for use as a cocktail for both intranasal and intravenous administration to augment the coverage of prevailing VoCs. Variants of interest, such as Lambda (Peru) and others are constantly evaluated in Sorrento’s active surveillance program.

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.
