U.S. Food and Drug Administration (FDA) Has Accepted the New Drug Application (NDA) for Ensartinib

On March 13, 2024 Xcovery Holdings, Inc., an oncology focused pharmaceutical company, reported that the U.S. Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) for ensartinib, an Anaplastic Lymphoma Kinase (ALK) inhibitor for the treatment of adult patients with metastatic ALK-positive non-small cell lung cancer (NSCLC) (Press release, Xcovery, MAR 13, 2024, View Source [SID1234641130]). The filing is based on the results of the eXalt3, a randomized global phase III study designed to evaluate the efficacy and safety of ensartinib vs crizotinib in the first-line treatment of ALK-positive NSCLC. The FDA granted the application Standard Review and assigned a Prescription Drug User Fee Act (PDUFA) goal date of December 28, 2024.

"The FDA’s acceptance of this NDA represents a key milestone for Xcovery in its mission to bring ensartinib as a novel and distinct first-line therapeutic option to ALK-positive NSCLC patients"

"The FDA’s acceptance of this NDA represents a key milestone for Xcovery in its mission to bring ensartinib as a novel and distinct first-line therapeutic option to ALK-positive NSCLC patients," said Giovanni Selvaggi, M.D., Chief Medical Officer of Xcovery. "We will continue to work closely with the agency during the review period. This achievement is a testament to our patient-centric vision and has been made possible by the dedication and skills of the entire Xcovery team and stakeholders, with the constant support of the patients, their families and investigators in our clinical trials globally."

Ensartinib is a next generation ALK inhibitor jointly developed by Xcovery and Betta Pharmaceuticals. In the clinical trials, the drug has demonstrated robust and durable responses in ALK-positive NSCLC patients (both systemically and in the brain), with an extensively studied and well manageable safety profile. The results of the eXalt3 were originally published in JAMA Oncology in September 2021.

"The US has the highest rate of avoidable cancer and cardiometabolic-related deaths among any high-income country. We must do better," said Grant Verstandig, Zephyr AI’s Co-Founder and Executive Chairman. "At Zephyr AI, we are harnessing the power of AI to extract novel insights to better define patient stratification and response predictions as well as improve federation of real-world data. With our world-class team, and the support of this investor group, we are deploying one of the largest clinicogenomic datasets that has unprecedented breadth across disease states and data partners. Collectively, we are now well positioned to support our mission of democratizing precision medicine, enhancing both the speed and success of clinical trials."

According to Dr. Justin Stebbing, Chairman of Zephyr AI’s Scientific and Medical Advisory Board, Editor of Oncogene (published under the Nature portfolio), and Professor of Biomedical Sciences at ARU, Cambridge, the company’s technology stands out along two crucial dimensions. "First, it has empirically demonstrated the ability to navigate the intricacies of real-world patient data, historically a challenge in the field. Second, leveraging recent breakthroughs in representation learning, the technology elucidates the biological context underlying its predictions. This contextual understanding is pivotal in drug development decision-making, revealing patient selection insights unpredictable using today’s tools to maximize the value of both approved medicines and drugs in development."

The new funds will enable Zephyr AI to further enhance its analytical speed and fortify its extensive collection of training and validation data sets. Moreover, the funds will support the expansion of the company’s scientific and commercial teams to expedite the delivery of its rapidly growing pipeline of insights to the market.

"The expansion of our diverse multimodal data resources will accelerate the advancement of Zephyr AI’s algorithms, paving the way for us to transform the landscape of precision medicine and improve outcomes for our partners and patients," said Jeff Sherman, Co-Founder, Interim CEO, and Chief Technology Officer of Zephyr AI.

Zephyr AI has had two abstracts accepted for publication at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) annual meeting to be held in San Diego on April 5-10, 2024.

1)

Abstract # 3519/11: Reconstructing a latent representation of gene expression from genomic alterations to improve clinical utility of real-world clinicogenomics data presented by Maayan Baron et al., Monday April 8th, 1.30 – 5.00pm

2)

Abstract #7373/1: Generative Bayesian networks for augmentation of molecular data from commercial genetic panels presented by Dillon Tracy et al., Wednesday April 10th 9.00 – 12.30pm

"We are excited to be part of this growing ecosystem of AI-enabled drug development and welcome the opportunity to attend AACR (Free AACR Whitepaper) where we will engage with the scientific community and present some of our emerging scientific insights from our platform," Sherman said.
