New Phase 3 Study for Eye Care Shows Promise for Diabetic Retinopathy Treatment
Key Takeaways
- Tarcocimab tedromer could revolutionize diabetic retinopathy treatment by improving eye health over longer intervals.
- The promising results from the GLOW1 study have led to the initiation of the GLOW2 study.
- Kodiak Sciences is actively conducting and planning additional studies to solidify the role of tarcocimab in treating various retinal conditions.

Introduction to the GLOW2 Study
Kodiak Sciences Inc. has started treating the first patients in its Phase 3 GLOW2 study, focusing on diabetic retinopathy (DR). This study is a continuation of the GLOW1 study and aims to assess the effectiveness and safety of the drug tarcocimab tedromer in treating this eye condition.
Background on Tarcocimab Tedromer
Tarcocimab tedromer is an investigational drug designed to help manage diabetic retinopathy. It belongs to the class of anti-VEGF therapies, which work by blocking a protein that can cause abnormal blood vessel growth in the eye, leading to vision problems. What makes tarcocimab unique is its ability to maintain effective drug levels in the eye for extended periods.
Details of the GLOW2 Study
The GLOW2 study is a multi-center, double-masked trial, meaning neither the researchers nor the patients know who is receiving the active treatment versus a placebo. This setup helps ensure unbiased results. In this study, all patients will receive doses of tarcocimab at intervals of up to six months.
The primary goal is to see if patients' eye health improves by at least two steps on the Diabetic Retinopathy Severity Scale (DRSS) after 48 weeks of treatment. The study also looks at secondary outcomes, such as the prevention of severe eye complications and more significant improvements on the DRSS.
Results from the GLOW1 Study
The earlier GLOW1 study demonstrated promising results, with patients seeing a significant improvement in their DRSS scores and a reduced risk of developing severe eye issues. Specifically, patients treated with tarcocimab had a 29-fold increase in response rate for a ≥ 2-step improvement in DRSS and an 89% reduction in the risk of sight-threatening complications over 48 weeks.
Why This Study Matters
For many patients with diabetic retinopathy, existing treatments only maintain the current condition without making significant improvements. Tarcocimab aims to be a game-changer by not only preventing worsening conditions but also by improving patients' eye health.
If successful, the GLOW2 study could provide essential support for the approval of tarcocimab, enhancing treatment options for those with diabetic retinopathy.
Additional Ongoing Studies
Kodiak Sciences is not stopping with just one condition. The company is also running several other Phase 3 studies, including the BEACON study for retinal vein occlusion and the DAYLIGHT study for wet age-related macular degeneration (AMD).
The DAYBREAK study is set to start in mid-2024 and aims to assess the effectiveness of tarcocimab and other investigational drugs for wet AMD, further positioning tarcocimab as a competitor in the retina treatment market.
Future Prospects
The ongoing and upcoming studies provide hope for better treatment options for patients with retinal conditions. With the primary and secondary endpoints met in the recent GLOW study, Kodiak Sciences is optimistic about the future of tarcocimab.
Patient Impact
If all goes well, tarcocimab could drastically change the treatment landscape for diabetic retinopathy, offering longer durations between treatments and better overall eye health outcomes. Patients would benefit from fewer visits to the doctor and potentially better protection against vision loss.
