Kodiak Sciences Completes Enrollment in BEACON Phase 3 Clinical Trial of KSI-301 in Patients with Retinal Vein Occlusion

Over 550 patients with macular edema secondary to Retinal Vein Occlusion enrolled worldwide

PALO ALTO, Calif., Dec. 16, 2021 /PRNewswire/ -- Kodiak Sciences Inc. (Nasdaq: KOD), a biopharmaceutical company committed to researching, developing and commercializing transformative therapeutics to treat high prevalence retinal diseases, today announced that it has completed enrollment in its BEACON Phase 3 clinical trial of KSI-301, Kodiak's anti-VEGF antibody biopolymer conjugate, in patients with macular edema due to retinal vein occlusion ("RVO").

"We are very pleased to have completed enrollment in BEACON, and we look forward to the six-month primary endpoint data," said Jason Ehrlich, MD, PhD, Kodiak's Chief Medical and Development Officer. "Retinal vein occlusion is an important cause of vision loss, and current FDA approved anti-VEGF therapies are labeled only for monthly dosing in RVO. In BEACON, we are studying KSI-301's potential to be a longer-lasting treatment for patients. Looking to the first quarter of next year, the Kodiak clinical development team is focused on completing enrollment in our paired GLEAM and GLIMMER Phase 3 clinical studies in patients with diabetic macular edema and also delivering topline results from our DAZZLE Phase 2b/3 study in patients with wet AMD."

About KSI-301

KSI-301 is an investigational anti-VEGF therapy built on Kodiak's Antibody Biopolymer Conjugate (ABC) Platform and is designed to maintain potent and effective drug levels in ocular tissues for longer than existing available agents. Kodiak's objective with KSI-301 is to develop a new first-line agent to improve outcomes for patients with retinal vascular diseases and to enable earlier treatment and prevention of vision loss for patients with diabetic eye disease. The KSI-301 clinical program is designed to assess KSI-301's durability, efficacy and safety in wet AMD, DME, RVO and non-proliferative DR (without DME) through clinical studies run in parallel. The Company's DAZZLE and DAYLIGHT pivotal studies in patients with treatment-naïve wet AMD, GLEAM and GLIMMER pivotal studies in patients with diabetic macular edema, and the BEACON pivotal study in patients with retinal vein occlusion are anticipated to form the basis of the Company's initial BLA to support potential approval and commercialization in multiple indications and with a full range of labeled and reimbursable dosing frequencies in each indication. An additional Phase 3 pivotal study, GLOW, in patients with non-proliferative diabetic retinopathy is also underway. The global KSI-301 clinical program is being conducted at 150+ study sites in more than 10 countries. Kodiak is developing KSI-301 and owns global rights to KSI-301.

About the BEACON Study

The Phase 3 BEACON study is a global, multi-center, randomized study designed to evaluate the durability, efficacy and safety of KSI-301 in patients with treatment-naïve macular edema due to retinal vein occlusion (RVO), including both branch and central subtypes. Patients are randomized to receive either intravitreal KSI-301 every eight weeks after only two loading doses or monthly intravitreal aflibercept per its label, for the first six months. In the second six months, patients in both groups will receive treatment on an individualized basis per protocol-specified criteria. Following this, patients can continue to receive KSI-301 for an additional six months on an individualized basis. The study has enrolled over 550 patients worldwide. The primary endpoint is at six months, and patients will be treated and followed for 18 months. Additional information about the BEACON study (also called Study KS301P103) can be found on www.clinicaltrials.gov under Trial Identifier NCT04592419 (https://clinicaltrials.gov/show/NCT04592419).

About the DAZZLE Study

The Phase 2b/3 DAZZLE study is a global, multi-center, randomized pivotal study designed to evaluate the durability efficacy and safety of KSI-301 in patients with treatment-naïve wet AMD. Patients are randomized to receive either KSI-301 on an individualized dosing regimen as infrequently as every five months and no more often than every three months or to receive aflibercept on its labeled every eight-week dosing regimen, each after three monthly initiating doses. The study has enrolled over 550 patients worldwide. The primary endpoint is at one year, and topline data are expected in early 2022. Each patient will be treated and followed for two years. Additional information about DAZZLE (also called Study KSI-CL-102) can be found on www.clinicaltrials.gov under Trial Identifier NCT04049266 (https://clinicaltrials.gov/show/NCT04049266).

About the GLEAM and GLIMMER Studies

The Phase 3 GLEAM and GLIMMER studies are global, multi-center, randomized pivotal studies designed to evaluate the durability, efficacy and safety of KSI-301 in patients with treatment-naïve diabetic macular edema (DME). In each study, patients are randomized to receive either intravitreal KSI-301 on an individualized dosing regimen every eight to 24 weeks after only three loading doses or intravitreal aflibercept every eight weeks after five loading doses per its label. Each study is expected to enroll approximately 450 patients worldwide. The primary endpoint for both studies is at one year, and patients will be treated and followed for two years. Additional information about GLEAM (also called Study KS301P104) and GLIMMER (also called Study KS301P105) can be found on www.clinicaltrials.gov under Trial Identifiers NCT04611152 and NCT04603937, respectively (https://clinicaltrials.gov/ct2/show/NCT04611152 and https://clinicaltrials.gov/ct2/show/NCT04603937).

About the DAYLIGHT Study

The Phase 3 DAYLIGHT study is a global, multi-center, randomized pivotal study designed to evaluate the efficacy and safety of high-frequency KSI-301 in patients with treatment-naïve wet AMD. Patients are randomized to receive either KSI-301 on a monthly dosing regimen or to receive standard-of-care aflibercept. The study is expected to enroll approximately 500 patients worldwide. The primary endpoint is at ten months, and the study is being planned and executed to allow for inclusion of its results in the initial BLA for KSI-301 along with the DAZZLE, BEACON, GLEAM and GLIMMER studies. The intent of this pivotal study is to broaden KSI-301's potential product labeling, explore the potential for improved treatment outcomes in certain patients with intensive anti-VEGF treatment, and eliminate possible barriers to market access and insurance reimbursement that have impeded or complicated the commercial uptake of other anti-VEGF medications in the past. We believe that pursuing a broad product label will provide physicians with the flexibility, agency, and reimbursement confidence required to consider KSI-301 treatment for all their patients. Additional information about DAYLIGHT (also called Study KS301P107) can be found on www.clinicaltrials.gov under Trial Identifier NCT04964089 (https://clinicaltrials.gov/show/NCT04964089)

About the GLOW Study

The Phase 3 GLOW study is a global, multi-center, randomized pivotal study designed to evaluate the efficacy and safety of KSI-301 in patients with treatment-naïve, moderately severe to severe non-proliferative diabetic retinopathy (NPDR). Patients are randomized to receive either KSI-301 on a once every six-month dosing regimen after three initiating doses or to receive sham injections. The study is expected to enroll approximately 240 patients worldwide. The primary endpoint is at one year and patients will be treated and followed for two years. Outcomes include changes in diabetic retinopathy severity, measured on a standardized photographic grading scale, and the rate of development of sight-threatening complications due to diabetic retinopathy. Additional information about GLOW (also called Study KS301P106) can be found on www.clinicaltrials.gov under Trial Identifier NCT05066230 (https://clinicaltrials.gov/show/NCT05066230).
