Dizal Announces Patient Enrollment Completion in Phase III Trial
Dizal Completes Patient Enrollment for Pivotal Phase III Study
Dizal has successfully finalized patient enrollment for its significant WU-KONG28 clinical trial. This pivotal study aims to evaluate the efficacy and safety of sunvozertinib versus platinum-based doublet chemotherapies in treatment-naïve non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) exon 20 insertion mutations, also known as exon20ins.
Challenges in Treating EGFR Exon20 Insertion Mutations
The landscape of treating EGFR exon20ins has proven to be exceptionally challenging. These mutations exhibit a unique spatial configuration, leading to diverse mutation subtypes and high variability. Consequently, patients with this condition face a grim prognosis and have access to limited treatment options. The effectiveness of commonly used EGFR tyrosine kinase inhibitors (TKIs) for these patients is often disappointing, necessitating alternative solutions.
Exploring the Potential of Sunvozertinib
Sunvozertinib stands out as the first oral medication approved for treating NSCLC patients with EGFR exon20ins. This innovative drug has shown remarkable efficacy, coupled with a favorable safety profile in clinical settings. Both the U.S. Food and Drug Administration (FDA) and the Chinese National Medical Products Administration (NMPA) have recognized the drug's potential, awarding it the Breakthrough Therapy designation for the treatment of EGFR exon20ins NSCLC.
A Multinational Clinical Trial
The WU-KONG28 trial spans across 16 countries and assesses sunvozertinib against platinum-based chemotherapies in treatment-naïve patients with EGFR exon20ins. At the recent European Society for Medical Oncology (ESMO) Annual Meeting, Dizal presented groundbreaking results showing that sunvozertinib led to a complete reduction of target lesions in 100% of participants. Moreover, the objective response rate (ORR) was an impressive 78.6%, with a median progression-free survival (mPFS) of 12.4 months for advanced or metastatic patients with this specific mutation.
Regulatory Progress and Future Prospects
In addition to being approved in China for relapsed and refractory cases, sunvozertinib is on the verge of potential approval in the U.S. The FDA has granted priority review for the New Drug Application (NDA) for the same indication, with an established PDUFA date set in the near future.
About Sunvozertinib
Sunvozertinib, also known by its research designation DZD9008, is an irreversible EGFR inhibitor developed by Dizal's dedicated team. It targets a wide array of EGFR mutations while selectively sparing the wild-type form of the receptor. In recent months, sunvozertinib received NMPA approval for treating advanced NSCLC post-platinum chemotherapy, substantiated by data from the pivotal WU-KONG6 study. This study showed the drug's effectiveness not only in EGFR exon20ins but also in other types of EGFR mutations, further expanding its potential reach.
Safety Profile and Ongoing Studies
The drug has demonstrated a well-tolerated safety profile in clinical trials, with most treatment-emergent adverse events (TEAEs) classified as Grade 1 or 2 and deemed manageable. Currently, there are two pivotal ongoing studies evaluating sunvozertinib. One focuses on its application beyond the second line (WU-KONG1 Part B), while the other assesses its efficacy as a first-line treatment (WU-KONG28).
