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 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 clinicaltrials.gov (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.

About Lupus (Systemic Lupus Erythematosus / SLE)

Lupus is a chronic inflammatory disease which is thought to affect some 5 million individuals worldwide. The current standard of care still consists of steroid and anti-malarial therapies which many have side-effects and poor response in many patients. Recently more targeted monoclonal therapies are GlaxoSmithKline's Benlysta and more recently, AstraZeneca's Saphnelo. There still exists a high unmet medical need for a drug that has a strong efficacy and safety profile.
