News Release
Sorrento Announces Significant Positive Pivotal Trial Results as Assessed by an Independent Review Committee (IRC) With Matured Long-Term (Over Three Years) Follow-Up Data of Abivertinib for the Treatment of Advanced Non-Small Cell Lung Cancer (NSCLC)
- Abivertinib is a novel third-generation epidermal growth factor receptor (EGFR) inhibitor that irreversibly targets mutant forms of EGFR in advanced NSCLC patients who are resistant to first-line EGFR kinase inhibitor therapies.
- In this pivotal study conducted in
China , matured data of 209 response evaluable NSCLC patients were assessed by an IRC. The overall response rate (ORR) as confirmed by the IRC was 56.5% (118/209) and among them, 11 patients had complete responses (CR) with a CR rate of 5.3% (11/209) and median overall survival (OS) of 28.2 months. - Based on these significant positive results from the IRC assessment, Sorrento is closing the study and preparing the materials for a pre-New Drug Application (NDA) meeting with the FDA and potentially submitting for approvals to regulatory agencies of other countries.
Abivertinib is a pyrrolopyrimidine-based, third-generation EGFR inhibitor, which is structurally distinct from osimertinib. Abivertinib selectively inhibits EGFR-activating and resistant mutation with nearly 300-fold greater potency as compared with wild-type EGFR. Previously, a positive interim result assessed by investigators was published in the peer-reviewed
“We are very encouraged by the significant positive results of Abivertinib assessed by the IRC with long-term follow up data and look forward to meeting with the FDA and other regulatory authorities for the possibility of bringing Abivertinib to the

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 next-generation tyrosine kinase inhibitors (TKIs), 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 STI-1558, COVISHIELD™ and COVIDROPS™; 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 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
