Lupuzor™ Update

Phase 2/3 adaptive study design for Lupus study agreed with Avion

ImmuPharma PLC (LSE:IMM), the specialist drug discovery and development company, provides an update to the market on its Lupuzor™ programme in patients with systemic lupus erythematosus ("SLE")

Key highlights:

· In conjunction with its partner Avion Pharmaceuticals ("Avion"), ImmuPharma confirms that a Phase 2/3 adaptive trial will be the best design for the next clinical study of Lupuzor™ in SLE patients

· The study is targeted to commence in H2 2023 following submission through the FDA/PDUFA* process

ImmuPharma confirms that with its partner Avion, they have agreed on an adaptive Phase 2/3 study for Lupuzor™ in SLE patients. This is a one-protocol pivotal study which allows exploration of a dose-range in the Phase 2 part of the study, followed by seamless progression into the Phase 3 part of the study at the chosen dose. The overall timelines for the lupus clinical program are faster as one avoids the need for stopping and starting two independent trials, regulatory checks, ethics approvals and site set-ups.  It is also expected to be less costly overall. There is also an opportunity, through an interim analysis in the Phase 3 part of the study, to stop the study earlier if an efficacy signal is reached after a certain percentage of patients have been treated. 

This new study design incorporates guidance from the Food and Drug Administration ("FDA") which advised exploration of higher dose levels than have been used in the clinical program to date. A clean safety profile has already been established at higher doses. The ImmuPharma/Avion team, together with external advisors, are now preparing an updated clinical protocol.

Commenting on the announcement, Tim McCarthy, CEO of ImmuPharma, said:

"We have had extremely productive discussions with Avion over the last few weeks on the Lupuzor™ programme and we have agreed that the optimum way forward for Lupuzor™ is to u ndertake an adaptive Phase 2/3 trial.  Our key focus will be to commence the trial during H2 2023."

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.

About PDUFA

The Prescription Drug User Fee Act (PDUFA) was a law passed by the  United States Congress  in 1992 which allowed the  Food and Drug Administration  (FDA) to collect fees from  drug manufacturers  to fund the new  drug  approval process. The Act provided that the FDA was entitled to collect a substantial application fee from drug manufacturers at the time a  New Drug Application (NDA) or  Biologics License Application  (BLA) was submitted, with those funds designated for use only in  Center for Drug Evaluation and Research  (CDER) or  Center for Biologics Evaluation and Research  (CBER) drug approval activities. In order to continue collecting such fees, the FDA is required to meet certain performance benchmarks, primarily related to the speed of certain activities within the NDA review process.
