This clinical trial involves 54 centers and is led by Prof. Shun Lu (陸舜) fromShanghai Chest Hospital (上海市胸科醫院). The clinical trial approval was granted by China’s National Medical Products Administration (“NMPA”) on 1 March 2021, and the first patient was enrolled on 15 July 2021. A total of 498 patients have been enrolled into the study. An interim analysis is expected to be conducted in April 2023.
Fully human antibody potentially allows it to have minimal immunogenicity; demonstrated by its negative antigen-derived antibody (ADA) generation in humans in studies to date.
Potentially lower dose required to achieve efficacy compared to other anti-PD-L1 antibodiesPD-L1 antibodies.
Dual mechanism of action observed with both immune-checkpoint inhibition and antibody-dependent cellular cytotoxicity (ADCC) effect.
The treatment was a major milestone and the first new treatment for the aggressive cancer in decades; it increased the median overall survival by 2 months and reduced the risk of death by 23% compared with chemotherapy alone in this disease setting. The advance was celebrated as a major milestone. Durvalumab, another PD-L1 inhibitorPD-L1 inhibitor, has been granted the New Drug Approval (NDA) in ES-SCLC in China early this month. No PD-1 inhibitorPD-1 inhibitor has been approved in this indication.
COF is a subsidiary of Lee’s Pharm and a clinical development stage company focused on oncology. COF is currently developing several assets, including Socazolimab (anti-PD-L1 antibodyPD-L1 antibody) in pivotal clinical trial stage; Zotiraciclib, an oral multi-kinase inhibitor in Phase I clinical trial for glioblastoma; Gimatecan, a topoisomerase I inhibitor for ovarian cancer; Pexa-vec (oncolytic virus) which is in global Phase Ib clinical trial for renal cell cancer. COF has built a pipeline of 10 assets through internal development and in-licensing. The diversity of its products creates a unique position for the company to use immune oncology as backbone therapy in combination with in-house products and develop potential paradigm-shifting treatment for cancer.

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, COVISHIELD™ and COVI-MSC™; and diagnostic test solutions, including COVIMARK™.
Sorrento's commitment to life-enhancing therapies for patients is also demonstrated by our effort to advance a first-in-class (TRPV1 agonistTRPV1 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 postherpetic neuralgia (PHN). RTX has been cleared for a Phase II trial for intractable pain associated with cancer and a Phase II trial in osteoarthritis patients. Positive final results from the Phase III Pivotal Trial C.L.E.A.R. Program for SEMDEXA™, its novel, non-opioid product for the treatment of lumbosacral radicular pain (sciatica), were announced in March 2022. ZTlido® was approved by the FDA on February 28, 2018.
