The application was made based on the positive results from OL-ADCT-402-001, a Phase 2 bridging clinical trial for ZYNLONTA. The study was designed to evaluate the efficacy and safety of ZYNLONTA as a single-agent treatment for Chinese patients with r/r DLBCL.
Professor Zhu Jun, principal investigator of the OL-ADCT-402-001 study and Party Secretary of Beijing Cancer Hospital and Director of Internal Medicine, said: "Safer and more effective treatments are still urgently needed to address significant unmet medical needs among r/r DLBCL patients after two or more lines of systemic therapy in China. I hope ZYNLONTA will be accessible to Chinese r/r DLBCL patients soon."
"We are pleased with the swift progress of the development program for ZYNLONTA in China as evidenced by the NMPA’s recent acceptance of the BLA and priority review designation," said Ameet Mallik, Chief Executive Officer of ADC Therapeutics. "This is a significant step forward in our commitment to making ZYNLONTA available to benefit patients worldwide."
Ed Zhang, Co-founder and CEO of Overland Pharmaceuticals, said: "This is a meaningful milestone. Our partnership with ADC Therapeutics began in December 2020, and it took us only two and a half years to complete the clinical study and submit the first BLA. We would like to extend our sincere gratitude to participating patients, clinical investigators, the health authority and our partner ADC Therapeutics for their strong support in making this achievement possible. We look forward to our continued collaboration with all stakeholders to maximize the potential benefits of ZYNLONTA for patients in China."
Overland ADCT BioPharma holds the exclusive rights to develop and commercialize ZYNLONTA in Greater China and Singapore. The BLAs for ZYNLONTA have already been submitted in Singapore, Hong Kong and Taiwan. It is expected to address the unmet needs of patients with r/r DLBCL across these regions.
About ZYNLONTA (loncastuximab tesirine-lpyl)
The U.S. Food and Drug Administration (FDA) and the European Medicines Agency have approved ZYNLONTA (loncastuximab tesirine-lpyl) for the treatment of adult patients with relapsed or refractory (r/r) large B-cell lymphoma after two or more lines of systemic therapy, including DLBCL not otherwise specified, DLBCL arising from low-grade lymphoma and also high-grade B-cell lymphoma. The trial included a broad spectrum of heavily pre-treated patients (median three prior lines of therapy) with difficult-to-treat disease, including patients who did not respond to first-line therapy, patients refractory to all prior lines of therapy, patients with double/triple hit genetics and patients who had stem cell transplant and CAR-T therapy prior to their treatment with ZYNLONTA. This indication is approved by the FDA under accelerated approval and in the European Union under conditional approval based on overall response rate and continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
