Polaris Group Initiates Rolling Submission of Biologic License Application (BLA) for ADI-PEG 20 with U.S. FDA to Treat Malignant Pleural Mesothelioma

TAIPEI, Taiwan and SAN DIGEO, CA, USA I November 16, 2023 I Polaris Group (The Company, TWSE:6550), today announced that the Company has initiated the rolling submission of its Biologic License Application (BLA) for ADI-PEG 20 to the U.S. Food and Drug Administration (FDA) for the systemic treatment of patients with malignant pleural mesothelioma with non-epithelioid histology, in combination with a platinum agent and pemetrexed. This submission is based on the results of the successful phase 3 trial of ADI-PEG 20 in combination with a platinum agent and pemetrexed which met both its primary and secondary objectives for progression free survival and overall survival. The rolling submission process allows for the submission of individual modules of the BLA as they are completed, which can streamline the regulatory review process and may expedite the potential approval timeline.

This initial submission to the U.S. FDA includes the nonclinical and clinical portions of the BLA for ADI-PEG 20, with plans to finalize the remaining chemistry, manufacturing, and controls components in the coming months. When the final portion of the BLA is submitted, Polaris Group will actively seek priority review status for this BLA, which, if granted, could expedite the regulatory review process.

Dr. John Bomalaski, Executive Vice President of Medical Affairs at Polaris Group, commented, "Our clinical trials have demonstrated promising results, with ADI-PEG 20 showing statistically significant potential to address the medical needs of patients with malignant pleural mesothelioma. Our comprehensive development program is designed to provide robust data that supports the FDA's review of our BLA."

Howard Chen, CEO and Chairman of Polaris Group, added, "We are fully committed to addressing the urgent medical needs of patients facing malignant pleural mesothelioma. Today’s submission brings us one step closer to expanding treatment options for patients impacted by MPM in the U.S. If approved by the FDA, this therapy would be a welcome addition to treatment options for patients and an important step forward for our work in hard-to-treat cancers. We look forward to collaborating closely with the FDA throughout the review process."
