This study has been terminated.
Sponsored by: Merck
Information provided by: Merck
ClinicalTrials.gov Identifier: NCT00692614
  Purpose

This study will evaluate the treatment effect of three doses of the I-vation TA implant (MK0140) in diabetic patients with clinically significant macular edema.


Condition Intervention Phase
Macular Edema
Drug: triamcinolone acetonide
Phase II

Genetics Home Reference related topics: X-linked juvenile retinoschisis
MedlinePlus related topics: Edema
Drug Information available for: Triamcinolone acetonide Triamcinolone Triamcinolone diacetate Triamcinolone hexacetonide
U.S. FDA Resources
Study Type: Interventional
Study Design: Treatment, Randomized, Single Blind (Subject), Placebo Control, Parallel Assignment, Safety/Efficacy Study
Official Title: A Phase IIb, Randomized, Masked, Sham-Controlled, Clinical Trial to Study the Efficacy and Safety of the Helical Triamcinolone Acetonide Implant (MK0140) in Diabetic Patients With Clinically Significant Macular Edema

Further study details as provided by Merck:

Primary Outcome Measures:
  • Change from baseline in OCT retinal thickness; evaluate the safety and tolerability of doses. [ Time Frame: After 12 months of therapy. ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Evaluation of visual acuity; change from baseline in OCT center-point retinal thickness; the need for focal/grid laser photocoagulation during the study; the progression of diabetic retinopathy [ Time Frame: After 12 months of therapy. ] [ Designated as safety issue: No ]

Enrollment: 2
Study Start Date: September 2008
Primary Completion Date: September 2008 (Final data collection date for primary outcome measure)
