The path from an idea to a repurposed drug being made available to Patients is not always linear, though there are often some common Milestones :

• Identifying an appropriate drug to repurpose, i.e., a repurposing candidate
• Establishing the basic science behind a repurposing candidate (e.g. the drug’s Mechanism of action )
• Proving that the drug is effective in a relevant in vivo disease model
• Proving that the drug is safe and effective for the new Indication in human Clinical trials
• Determining an effective and appropriate Route to market
• Ensuring fair and equitable access to the drug for patients

Throughout a Drug repurposing project, the following should be considered:

• How to fund each drug development stage
• How to build the right development team with the right expertise for each development stage
• How and when to involve and engage with patients and Patient representatives
• How to maintain effective relationships with all Stakeholders (including regulators, Health technology assessment (HTA) experts, clinical teams, payers, etc.)
• How to manage a complex project to a high standard  

It is important at each stage to keep the end goal in mind – a new, safe and effective treatment reaching patients.
