Clinical Trial Outcome Measures
Primary Measures
- The incidence of adverse events
- Time Frame: 15 years
- The number and percentage of patients with treatment emergent adverse events
Secondary Measures
- Clinically important changes in ocular safety assessments
- Time Frame: baseline to 15 years
- From baseline in (TDU13600) study and from the last visit best-corrected visual acuity (BCVA), slit-lamp examination, fundososcopy, intraocular pressure, laboratory parameters, concomitant medications
- Delay in retinal degeneration
- Time Frame: baseline to 15 years
- Measured as change from baseline in function relative to untreated contralateral eye on: BCVA, static perimetry, autofluorescence, optical coherence tomography (OCT)
