THE PHARMA WAY REPURPOSING

THE PHARMA WAY REPURPOSING THEIR OWN DRUGS

REGULATORS: BARRIERS CREATED FOR PHARMA-HARD TO ACHIEVE FOR ACADEMICS FUNDERS: FINANCING TWO PHASE III DEVELOPMENT PLANS & REGULATORS DIFFICULT GOVERNMENT: NOT CREATING INCENTIVES/STRUCTURES

Cost: Simvastatin £2.70/week Cost Trial : £2-£50,000,000 Cost Regulators: £30,000/h

THE ACADEMIC WAY REPURPOSING

SCIENCE INNOVATION: IDENTIFY TARGETS LEAD TO PATENTS & COMMERCIAL DEVELOPMENT CLINICAL INNOVATION: IDENTIFY TARGETS FOR PHARMA EXPLOTATION IDENTIFTY TARGETS FOR PHARMA REPURPOSING LEAD TO PATENTS & COMMERCIAL DEVELOPMENT IDENTIFY METHODS TO DETECT EFFICACY RAPID PHASE II DESIGN ROBUST PHASE III TRIAL DESIGN SUPPORT THE CASE FOR A CHANGE IN REGULATION

THE ACADEMIC WAY REPURPOSING

CoI: Members of team are trying to commercially develop this drug We are shareholders/consultants and may gain financially from this.
