Not every movie wins an Oscar, and not every ophthalmology clinical trial leads to regulatory approval.
Behind every blockbuster film, there are months (or years) of meticulous planning — script revisions, casting decisions, rehearsals, and expert editing. Most of this effort happens behind the scenes, long before the audience sees the final product. The same applies to ophthalmology clinical trials, whether for age-related macular degeneration (AMD), diabetic retinopathy, glaucoma, rare ophthalmic diseases, and so on. While the results may seem straightforward (a treatment works, or it doesn’t), what happens behind the scenes determines whether a study becomes a regulatory success or a costly failure.
I divided this blog into two parts, breaking down how an ophthalmology trial moves from concept to regulatory approval, using the film industry as an analogy (or at least my best attempt, since I’m just a fan of movies). And now, I welcome you to Part 1 which covers the scriptwriting and casting phase of an ophthalmology trial: study protocol design, and patient/site selection.
🎬 Act 1: Pre-Production – A Clinical Trial Protocol: Your Trial’s Script
In Hollywood, a great movie starts with a strong script. Without a well-structured story, even the most talented directors and actors can’t save the film. Similarly, in ophthalmology clinical trials, the clinical trial protocol serves as a blueprint that guides:
- Clinical trial design
- Endpoint selection
- Patient inclusion/exclusion criteria
- Clinical trial data management strategies
- Randomization and trial supply management
- Statistical planning
Why It Matters
Poorly designed protocols lead to costly protocol amendments, delays, and even regulatory rejection. A well-planned protocol ensures efficiency, scientific credibility, and compliance with global regulatory standards.
Where Expertise Helps
Sponsors should engage early with CROs and clinical trial consulting teams to avoid trial design mistakes and ensure endpoints are aligned with FDA and EMA expectations, saving months of unnecessary rework.
Key Considerations for Study Protocol Development
- Choosing the Right Clinical Trial Endpoints: Just as the Oscars have strict judging criteria, regulatory agencies set specific expectations for ophthalmology clinical trials. Should BCVA, OCT biomarkers, or geographic atrophy (GA) progression be the primary endpoint?
- Analyzing One Eye or Both? Many trials historically analyzed only one eye, discarding valuable data. Advanced statistical methods can use data from both eyes, potentially improving statistical power and reducing required sample sizes.
- Avoiding Protocol Amendments: Poorly designed protocols lead to costly amendments, delaying approvals and increasing trial costs. Engaging clinical trial consulting experts early can prevent these inefficiencies.
🎬 Act 2: Casting – Selecting the Right Patients & Sites
Even the best screenplay needs the right cast to bring it to life. In clinical trials, choosing the right patient population and study sites is just as critical as casting the right actors in a movie.
Why It Matters
An ophthalmology trial that chooses the wrong sites or fails to identify high-potential recruitment regions can struggle to enroll enough patients, leading to delays and financial loss.
Where Expertise Helps
A well-designed clinical data management system and robust EDC clinical trials setup can optimize patient enrollment, track recruitment in real time, and ensure data consistency across sites.
Challenges in Ophthalmology Trial Recruitment:
- Rare Diseases or those that are Asymptomatic in Early Stages often make patient recruitment for clinical trials significantly more difficult.
- Strict Eligibility Criteria: Excluding patients with specific conditions can limit patient recruitment opportunities. It’s essential to evaluate and determine whether all criteria are necessary to keep scientific rigor while ensuring that the recruitment process is feasible within the timelines of the trial.
- Global Site Variability: Imaging equipment and diagnostic standards could be different across trial sites, affecting data consistency.
🎬 Part 1 Finale: Setting the Stage for Success in Ophthalmology Trials
Just like in filmmaking, the early phases of a clinical trial define the outcome. A poorly written screenplay can put at risk a movie before production even begins, and the same goes for ophthalmology trials. The first part of this blog covered the importance of a well-structured study protocol (Act 1) and the critical role of patient and site selection (Act 2). Without these elements carefully planned, recruitment challenges, protocol amendments, and site inconsistencies can derail your trial before it even gets fully underway.
But planning is only the beginning. Now comes execution:
- How do we ensure data collection meets the highest quality standards?
- Are trials properly handling the statistical complexities such as inter-eye correlation?
- How do we prepare for regulatory approval from the very start?
All of this will be covered in Part 2 of this Oscars-inspired blog, where I’ll explore the next three critical phases of a successful ophthalmology trial.
