Primary Outcome Measures:
  • The incidence of adverse events [ Time Frame: 24 weeks ]
    The number and percentage of patients with treatment emergent adverse events.

Secondary Outcome Measures:
  • Change from baseline in subretinal and intraretinal fluid as measured by OCT [ Time Frame: 24 weeks ]
    The change from baseline in the amount of subretinal and intraretinal fluid measured by Optical Coherence tomography

Enrollment: 21
Study Start Date: February 2011
Study Completion Date: May 2015
Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Subretinally Injected RetinoStat
Subretinally injected RetinoStat
Drug: Subretinally injected RetinoStat
Single subretinal injections, with increasing doses. 9 patients with 3 patients at each dose followed, by 12 patients at maximum tolerated dose.
Other Name: OXB-201

Detailed Description:
There are two parts to the study. A dose-escalation phase looking at three doses of RetinoStat starting with the lowest dose, three patients will be recruited at each dose level. The escalation phase will be followed by a dose confirmation phase where the highest dose that is safe and well tolerated will be examined in 9 patients.

Ages Eligible for Study:   50 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Clinical diagnosis of AMD with active CNV that shows evidence of leakage.
  • BCVA less than or equal to 20/200 in the study eye for dose escalation phase.
  • BCVA less than or equal to 20/80 in the study eye for maximum tolerated dose phase.

Exclusion Criteria:

  • Significant ocular abnormalities that prevent retinal assessment.
  • Treatment with steroids within three months of screening.
  • Treatment with anti-VEGF therapy to either eye within one month of screening.
  • Clinically significant intercurrent illnesses, laboratory, ECG or chest XRay abnormalities.
