SAN DIEGO, July 20, 2021 (GLOBE NEWSWIRE) -- Sorrento Therapeutics, Inc. (Nasdaq: SRNE) announced today that its partner Mabpharm Ltd (HK:2181) has received approval of its New Drug Application for its infliximab biobetter antibody in China.

Sorrento holds exclusive commercial rights to this product outside of China and plans to file a Biologics License Application (BLA) for the infliximab biobetter antibody in the United States and Europe in 2021.

Infliximab (currently marketed under the trade name Remicade) is an injectable monoclonal antibody prescription drug used to treat rheumatoid arthritis, Crohn's disease, ulcerative colitis, ankylosing spondylitis (a type of spinal arthritis), psoriatic arthritis, and the red, scaly skin patches of plaque psoriasis. Infliximab belongs to a class of drugs called tumor necrosis factor (TNF) inhibitors, which work by suppressing the action of a protein called TNF that is linked to inflammation. It is usually prescribed when other medicines or treatments have failed. Global sales revenue of infliximab in 2020 reached $4.2 billion, making the antibody one of the top 20 blockbuster drugs.

Mabpharm’s approved biobetter is an anti-TNF-α antibody using a CHO expression system, resulting in a better safety profile and lower immunogenicity when compared to the currently marketed TNF-α antibody using a murine cell line, while demonstrating the same efficacy as the parent mouse antibody. The Chinese approval covers 6 different indications including adult ulcerative colitis, ankylosing spondylitis, rheumatoid arthritis, adult and childhood Crohn’s disease, fistula Crohn’s disease, and psoriasis.

Sorrento is planning to meet with FDA and EMA to discuss the data package and gain concurrence on the path forward to a BLA or MAA.

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.
