FDA Grants Breakthrough Therapy Designation for Dizal Pharmaceutical's DZD9008 in Patients with Locally Advanced or Metastatic Non-Small Cell Lung Cancer Harboring EGFR Exon20 Insertion

Dizal Pharmaceutical Co., Ltd. (SHEX:688192) ("Dizal"), today announced that the U.S. Food and Drug Administration ("FDA") has granted Breakthrough Therapy Designation to DZD9008 (Sunvozertinib) for the treatment of patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon20 insertion mutations whose disease has progressed on or after platinum-based chemotherapy.

"Lung cancer patients with exon20 insertion mutations need better treatment. Sunvozertinib was specifically designed with high selectivity for inhibiting mutated EGFR, which causes cancers. Available clinical evidence shows that Sunvozertinib has the potential to provide the patients with a new and much improved targeted therapy," said Dr. Xiaolin Zhang, Chief Executive Officer at Dizal. "We are very pleased with FDA's decision. Now Sunvozertinib has received Breakthrough Therapy Designation from both US FDA and China CDE, which validates Sunvozertinib's differentiated profile.  At Dizal, we are committed to discover and develop innovative medicines for the benefit of cancer patients globally."

Breakthrough Therapy designation is a process designed by US FDA, China CDE, and other regulatory agencies to expedite the development and review of drugs that are intended to treat a serious condition, and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s)[1].
