Eagle Pharmaceuticals Announces Submission of Investigational New Drug Application to U.S. FDA for CAL02, a Novel First-in-Class Broad-Spectrum Anti-Virulence Agent for the Treatment of Severe Community-Acquired Bacterial Pneumonia

Eagle Pharmaceuticals, Inc. announced today that it has submitted an investigational new drug application to the U.S. Food and Drug Administration for CAL02, a novel first-in-class broad-spectrum anti-virulence agent for the treatment of severe community-acquired bacterial pneumonia.

  • Company plans to commence an adequately powered Phase 2 study with approximately 276 patients with severe community-acquired pneumonia at 120 sites worldwide with patient enrollment expected as early as the beginning of 2023
  • Interim results expected approximately one year after patient enrollment begins
  • CAL02 is being developed as an add-on to the clinically indicated antibiotic treatment and potentially offers unique therapeutic benefits to critically ill patients, including immediate decrease in inflammatory biomarkers, shorter duration of critical care management such as mechanical ventilation, and ultimately a reduced mortality risk

WOODCLIFF LAKE, N.J., Oct. 12, 2022 (GLOBE NEWSWIRE) -- Eagle Pharmaceuticals, Inc. (Nasdaq: EGRX) (“Eagle” or the “Company”) announced today that it has submitted an investigational new drug (“IND”) application to the U.S. Food and Drug Administration (“FDA”) for CAL02, a novel first-in-class broad-spectrum anti-virulence agent for the treatment of severe community-acquired bacterial pneumonia (“SCABP”).

The IND filing includes a protocol for an adequately powered global Phase 2 study to evaluate the efficacy and safety of CAL02 when added to standard of care therapy in patients with SCABP. The design, entry criteria, and endpoints for the proposed Phase 2 study have been discussed with the FDA in a pre-IND meeting held on September 19, 2022. The Phase 2 study plans to enroll approximately 276 patients with SCABP at 120 sites worldwide. Patient enrollment is expected as early as the beginning of 2023.

“CAL02 is a very interesting agent with a unique mechanism of action. The IND filing is an important regulatory milestone as it paves the way for us to begin what we believe will be a very robust Phase 2 proof-of-concept study. CAL02 has the potential to shift the treatment paradigm for patients with severe community-acquired pneumonia, a leading cause of death worldwide. Intended as an add-on to clinically indicated antibiotic treatment, CAL02 acts as a neutralizer of bacterial virulence factors, considered responsible for complications associated with severe pneumonia, and we believe it has the potential to shorten the need for costly critical care management, overall hospital stays, and improve patient outcomes,” stated Scott Tarriff, President and Chief Executive Officer of Eagle Pharmaceuticals. “In medical literature, CAL02 has been referred to as a medical breakthrough, and we are excited for the prospect of adding this important therapeutic to our acute care product portfolio,” concluded Tarriff.

“Severe community-acquired bacterial pneumonia is a challenging disease to treat and remains among the leading causes of death in infectious diseases worldwide.1 Historically, around one quarter2 of patients diagnosed with SCABP become critically ill, and the potential to use CAL02 in combination with traditional antibacterial drugs would provide physicians with a powerful tool to manage SCABP in critically ill patients and improve outcomes,” stated Dr. Andre Kalil, MD, MPH, University of Nebraska Medical Center.

Eagle anticipates filing for ten years of regulatory exclusivity, including five years as a new chemical entity and five years as a qualified infectious disease product (“QIDP”) under the Generating Antibiotic Incentives Now (“GAIN”) Act. Eagle believes that CAL02 could be eligible for fast track and breakthrough therapy designations. In addition, Eagle believes a CAL02 new drug application for the treatment of SCABP may qualify for priority review. The Company expects to strengthen the patent portfolio for this asset.

In August 2021, Eagle entered into a worldwide licensing agreement with Combioxin SA, a clinical-stage biotechnology company based in Epalinges, Switzerland, for the commercial rights to CAL02. As previously announced, the Company expects to invest $35 million to achieve interim results from the Phase 2 study expected in late 2023/early 2024.
