"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].
