Dizal's sunvozertinib receives US FDA Breakthrough Therapy Designation
8 April 2024 -

Dizal (688192.SH), a China-based biopharmaceutical company, announced on Sunday that it has received Breakthrough Therapy Designation from the US Food and Drug Administration (FDA) for its sunvozertinib as the first-line treatment for patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harbouring epidermal growth factor receptor (EGFR) exon 20 insertion (Exon20ins) mutations.

The approval is based on results from the global multi-centre phase I/II study (WU-KONG1). Dizal reported main study results, showing sunvozertinib as a single agent with confirmed objective response rate (cORR) of 78.6% and a median progression-free survival (mPFS) of 12.4 months, at 2023 ESMO.

Xiaolin Zhang PhD, Dizal CEO, said, 'We are delighted with the FDA's decision granting the Breakthrough Therapy Designation to sunvozertinib for first-line treatment, coming on the heels of earlier BTD approval in later lines of therapy -- a clear indication of sunvozertinib's transformative potential in the treatment of patients with EGFR exon20ins NSCLC. Multiple clinical trials have consistently demonstrated sunvozertinib's significant clinical benefits to our patients. As a single, oral agent, it offers apparent advantages in both safety and patient compliance over chemotherapies and infusion. Now, enrolment for the global pivotal study in relapsed and refractory setting (WU-KONG1 PART B) has been completed, and we are going to report the study results as an oral presentation at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting. A randomized global phase III study in the first line setting (WU-KONG28) is well underway. This new BTD will enable us work more closely with the FDA and accelerate its clinical development and regulatory submission.'
