ImmuPharma PLC (LSE:IMM), the specialist drug discovery and development company, is pleased to announce that the Phase 2/3 adaptive clinical trial of P140 (Lupuzor™) in patients with systemic lupus erythematosus (“SLE/Lupus”) is to commence in H2 2023.

 Key highlights:

  • Following the receipt of comprehensive guidance from the Food and Drug Administration (“FDA”) in 3 separate Type-C meetings, a Phase 2/3 adaptive clinical trial of P140 (Lupuzor™) in patients with Lupus will commence in H2 2023.
  • Avion Pharmaceuticals (“Avion”) have confirmed that under the previously announced terms of the existing Licence Agreement, they will continue to support the new clinical trial design and Avion and ImmuPharma have agreed to proceed and will now begin preparatory steps for the Phase 2/3 adaptive clinical trial.
  • The trial design and protocol is substantially different from previous clinical trials that ImmuPharma has completed and includes maintaining subcutaneous dosing but at much higher concentrations and significant changes to patient inclusion criteria and primary and secondary clinical endpoints.

The detailed protocol and key elements of the clinical trial design will be communicated at a later stage once the details of the trial are available on (a comprehensive database of privately and publicly funded clinical studies conducted around the world).

Commenting on the announcement, Tim McCarthy, CEO of ImmuPharma, said:“We are delighted to be moving forward with the study for P140 (Lupuzor™) in Lupus after receiving comprehensive guidance from the FDA on the protocol. Avion and ourselves are confident in the new design of the Phase 2/3 adaptive clinical trial and in ultimately delivering a new efficacious and safe therapy for Lupus patients.

  Commenting further, Art Deas, CEO of Avion said:

 “The FDA has provided us with comprehensive guidance to commence the Phase 2/3 adaptive clinical trial for P140 (Lupuzor™) and we look forward to continue working closely with ImmuPharma to deliver a successful result for Lupus patients.”
