The Razorbill study

The Challenges:

The standard of care for nAMD is repeated intravitreal injection with anti-VEGFs injections.
Evidence shows that optimal outcomes are achieved with treatment frequency of approximately 8 injections/ year.
However, evidence also show that the average number of injections and treatment visits observed in real- world clinical situations are significantly lower than expected. Contributing factor to this undertreatment is an overwhelmed healthcare system which cause physicians to miss disease activity in 16.6%1 to 29.6%2 of OCT readings compared to Reading Centers.

Clinical studies are complex, expensive and time consuming.

Today the average time to bring a new drug to the market is ten to twelve years3.
The initial phase of R&D, drug discovery, can take five to six years, followed by an additional five to seven years for clinical trials.
To bring a new drug to the market takes an estimated average cost of $2.6 billion.
Key inefficiencies are:

- decentralized data in multiple locations
- long time (e.g. 9-10 months) to submit to regulatory approval, which then can take up.

2 challenges, 1 solution - Discovery®

The Razorbill study hypothesizes that Discovery will add specific supportive  information for a faster and more precise evaluation of anatomical signs of disease activity particularly in less specialised centres.

Discovery as a clinical study tool improve efficiency providing:

  • real-time transparency & accessibility
  • decentralized access to data
  • one-stop solution for: data collection (eCRFs)-image collection-image analysis-faster analysis supported by AI, quantification measurements

Study design

The study consists of two parts:

  • Prospective data collection
  • 5 countries
  • 18 clinics / sites

Key activities:

Anonymised patients’ files are uploaded to Discovery.
Additional data is collected through 5 eCRF templates

  • OCT Enrichment analysis
  • 5 countries
  • 36 reviewers

Key activities:

  • Patients are redistributed to reviewers automatically based on protocol logic
  • Each reviewer analyses patients with and without AI enhancement
  • OCT analysis data is collected through 1 eCRF template
