Kelun-Biotech's A400/EP0031 Advances in NSCLC Treatment Journey
Overview of Kelun-Biotech's New Drug Application
Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd. is excited to share that their groundbreaking drug application for A400, also referred to as EP0031, has officially been accepted for review by the National Medical Products Administration (NMPA). This next-generation selective RET inhibitor aims to offer new hope for adult patients suffering from RET-fusion positive non-small cell lung cancer (NSCLC).
Clinical Trials and Efficacy of A400/EP0031
The acceptance of the new drug application (NDA) stems from significant results derived from two pivotal Phase 2 cohorts in the KL400-I/II-01 study. These cohorts explored the efficacy and safety of A400/EP0031 administered at a dosage of 90 mg orally once daily. The trials focused on both patients who have undergone prior treatments and those who are new to treatment.
Results indicated that A400/EP0031 produced encouraging efficacy rates across both patient groups, even for those who had undergone prior immunotherapy or presented with brain metastases. The drug has also shown a promising safety profile, with manageable tolerability, presenting a vital option for this challenging patient population.
CEO Insights on A400/EP0031
Dr. Michael Ge, the CEO of Kelun-Biotech, expressed confidence in the drug's clinical potential, highlighting its status as a tumor-agnostic precision therapy. He noted that this represents a strategic advancement for the company in the solid tumor arena. The team is eager to collaborate closely with regulatory bodies to expedite the review process, aiming to bring A400/EP0031 to patients swiftly.
Understanding RET-fusion Positive NSCLC
RET gene fusions are recognized as a notable subtype of mutations contributing to non-small cell lung cancer. For patients afflicted with RET-fusion positive NSCLC, conventional treatment options offer limited effectiveness, which creates an urgent need for innovative solutions like A400/EP0031. The emergence of selective inhibitors has resulted in incremental improvements in managing advanced cases, albeit facing challenges from RET drug-resistant mutations and associated safety concerns.
The Innovative Drug: A400/EP0031
A400/EP0031 stands out as a promising next-generation selective RET inhibitor specifically designed for conditions such as NSCLC and medullary thyroid cancer (MTC). The company is actively engaged in a Phase 1b/2 clinical trial focused on RET mutations, currently underway.
Notably, the preliminary data from a Phase 1 study of A400/EP0031 presented at a recent annual meeting underscored the drug’s potential effectiveness in treating advanced RET-mutant MTC patients.
Recent Developments in Drug Approval Process
In a move aimed at accelerating the drug’s availability, the FDA granted A400/EP0031 Fast Track designation, opening doors for its progression into Phase 2 clinical developments. Currently, the drug is being analyzed across regions including the United States, the United Kingdom, Europe, and the United Arab Emirates.
