KSI-101 FDA Regulatory Timeline and Events
KSI-101 is a drug developed by Kodiak Sciences for the following indication: in patients with MESI.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- KSI-101
- Announced Date:
- May 1, 2026
- Indication:
- in patients with MESI
Announcement
Kodiak Sciences announced it will present pipeline advances and clinical results of KSI-101 in a cohort of tertiary care MESI patients at the 2026 American Uveitis Society (AUS) Meeting and the 2026 Association for Research in Vision and Ophthalmology (ARVO) Meeting.
AI Summary
Kodiak Sciences said it will present pipeline advances and clinical results for KSI-101 in a cohort of tertiary care patients with macular edema secondary to inflammation (MESI) at the American Uveitis Society meeting on May 2, 2026 in Aurora, Colorado, and at the Association for Research in Vision and Ophthalmology meeting, May 3–7, 2026 in Denver, Colorado.
Highlights include Phase 1b APEX data on KSI-101, with new results from a tertiary care Asian cohort that were consistent with U.S. findings. Those consistent outcomes support Kodiak’s plan to expand global development, including Phase 3 MESI programs PEAK and PINNACLE. At ARVO, Kodiak will, for the first time, present results from both the U.S. study and the Asian cohort.
Kodiak will have six poster presentations at ARVO; the posters and supporting materials will be posted on Kodiak’s “Scientific Presentations” page on kodiak.com.Read Announcement

Announcement
Kodiak Sciences announced participation at the virtual Angiogenesis (Angiogenesis, Exudation, and Degeneration) annual meeting on February 7, 2026.
AI Summary
Kodiak Sciences announced it will take part in the virtual Angiogenesis (Angiogenesis, Exudation, and Degeneration) annual meeting on February 7, 2026. At the meeting, Dr. Sumit Sharma, a retina and uveitis specialist at the Cole Eye Institute, will present first-time end‑of‑study clinical results from the Phase 1b APEX study, including Week 24 data in patients with macular edema secondary to inflammation (MESI).
The presentation will focus on KSI-101, Kodiak’s intravitreal biologic candidate. Kodiak says there are currently no approved intravitreal biologic therapies that address the full MESI spectrum, and it views MESI as a distinct market separate from anti‑VEGF treatments. Based on APEX results, the two highest dose levels moved forward into Phase 3. The PEAK and PINNACLE Phase 3 studies are actively enrolling MESI subjects at 5 mg and 10 mg doses versus sham.

Announcement
Kodiak Sciences Inc. announced today follow-up data from the APEX study of KSI-101 in patients with MESI.
AI Summary
Kodiak Sciences Inc. announced follow-up data from its Phase 1b APEX study of KSI-101 in patients with macular edema secondary to inflammation (MESI). KSI-101 is a high-strength, bispecific antibody that targets both interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF).
Meaningful vision improvements appeared as early as week 4 and continued through week 20. More than half of patients gained at least three lines on the eye chart (≥15 letters). At the highest two dose levels (5 mg and 10 mg), over 90% of patients achieved “real dryness” of the retina, with no intraretinal or subretinal fluid—key signs of disease activity.
The top two doses from APEX have advanced into Phase 3 PEAK and PINNACLE studies, which are enrolling faster than expected. KSI-101 was well tolerated, and Kodiak’s leadership believes these results support its potential as a safe, first-line therapy for a broad MESI population.

Announcement
Kodiak Sciences Inc. announced today new data from the APEX study of KSI-101 presented at the Retina Society 58th Annual Scientific Meeting in Chicago, Illinois.
AI Summary
Kodiak Sciences Inc. announced new data from its Phase 1b APEX study of KSI-101, presented at the Retina Society 58th Annual Scientific Meeting in Chicago. The study, led by Dr. Charles Wykoff, tested KSI-101 in patients with macular edema secondary to inflammation (MESI). Researchers saw rapid vision improvements and retinal drying over 12 weeks.
Patients showed meaningful vision gains as early as week 4, and more than half of those receiving the two highest doses (5 mg and 10 mg) improved by 15 letters or more on the eye chart. A single dose cleared intra- and sub-retinal fluid for most patients, and over 90% achieved retinal dryness by week 8. KSI-101 was well tolerated, with a favorable safety profile. Kodiak is now enrolling patients in its Phase 3 PEAK and PINNACLE studies, testing the 5 mg and 10 mg doses in MESI.

Tarcocimab tedromer FDA Regulatory Events
Tarcocimab tedromer is a drug developed by Kodiak Sciences for the following indication: In patients with diabetic retinopathy ("DR").
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- tarcocimab tedromer
- Announced Date:
- March 26, 2026
- Indication:
- In patients with diabetic retinopathy ("DR").
Announcement
Kodiak Sciences Inc announced positive topline results in the GLOW2 Phase 3 superiority study of Zenkuda™ for the treatment of patients with diabetic retinopathy. Zenkuda (tarcocimab tedromer) is an anti-vascular endothelial growth factor (VEGF) intravitreal biologic built on Kodiak's proprietary antibody biopolymer conjugate (ABC®) platform.
AI Summary
Kodiak Sciences Inc. reported positive topline results from the GLOW2 Phase 3 superiority study of Zenkuda™ for patients with diabetic retinopathy. Zenkuda (tarcocimab tedromer) is an anti-vascular endothelial growth factor (VEGF) intravitreal biologic built on Kodiak’s proprietary antibody biopolymer conjugate (ABC®) platform. The company said the trial met its main goals, suggesting Zenkuda could provide meaningful benefit for people with this eye disease.
Zenkuda also demonstrated superiority in the two alpha-controlled secondary endpoints with high statistical significance. Dr. Victor Perlroth, Kodiak’s CEO, said the data give Zenkuda a multi-indication, BLA-ready profile and that the company intends to accelerate its BLA submission plans. Full end-of-study results will be presented at an upcoming congress by Dr. Charles Wykoff.

- Announced Date:
- March 10, 2025
- Indication:
- In patients with diabetic retinopathy ("DR").
Announcement
Kodiak Sciences Inc. announced that it has completed enrollment in its GLOW2 Phase 3 clinical trial of tarcocimab tedromer in patients with diabetic retinopathy ("DR").
AI Summary
Kodiak Sciences Inc. announced that it has successfully completed enrollment for its GLOW2 Phase 3 clinical trial, which is evaluating tarcocimab tedromer in patients with diabetic retinopathy. The trial enrolled over 250 patients, surpassing its initial target. The GLOW2 study closely mirrors the design of the successful GLOW1 trial, with the added benefit of an extra loading dose, providing more dosing flexibility for healthcare providers. With a 48‐week treatment period, all patients are expected to complete their primary endpoint visits by the end of January 2026. Kodiak plans to announce the topline clinical data from GLOW2 in the first quarter of 2026, a step that could support the regulatory filing of tarcocimab if the outcomes continue to show promise in treating diabetic retinopathy.
