Diabetic Retinopathy Clinical Trial
Official title:
An Open-Label Dose Escalation Study of PF-04523655 (Stratum I) Combined With a Prospective, Randomized, Double-Masked, Multi-Center, Controlled Study (Stratum II) Evaluating the Efficacy and Safety of PF-04523655 Alone and in Combination With Ranibizumab Versus Ranibizumab Alone in Diabetic Macular Edema (MATISSE STUDY)
This is a two-part study. The first part (Stratum I) is an open-label, dose escalation, safety, tolerability and pharmacokinetic study, where active study drug (PF-04523655) will be given to all patients who participate. Stratum I will determine the maximum tolerated dose and any dose-limiting toxicities. The second part (Stratum II) is a prospectively randomized, multi-center, double-masked, dose ranging study evaluating the efficacy and safety of PF-04523655 alone and in combination with ranibizumab versus ranibizumab alone in patients with DME.
Patients will be enrolled concurrently according to one of two sets of criteria designated
as Stratum I and Stratum II.
1. Stratum I will enroll up to 24 subjects with low vision, inclusive of possible
intermediate doses, in up to 4 cohorts of 3-6 evaluable subjects.
2. Stratum II will enroll approximately 240 subjects with DME 1:1:1:1 in up to 4 cohorts
of 60 evaluable subjects.
