A Safety Surveillance Study in Subjects With Macular Degenerative Disease Treated With Human Embryonic Stem Cell-derived Retinal Pigment Epithelial Cell Therapy

Phase 1
Conditions
Macular Degenerative Disease
Interventions
Biological: Human Embryonic Stem Cell-Derived Retinal Pigment Epithelial Cells
Registration Number
NCT03167203
Lead Sponsor
Astellas Institute for Regenerative Medicine
Brief Summary

The purpose of this study is to is to evaluate the occurrence of late onset (i.e., greater than 5 years after treatment) adverse events of special interest (AESI) in participants who have received sub-retinal transplant of human embryonic stem cell derived - retinal pigment epithelial (hESC-RPE) cells in an AIRM-sponsored clinical trial. The events of special interest are adverse events (AEs) that are presumed to have a potential causal relationship to the hESC-RPE cells.

Detailed Description

Participants will be contacted by the Patient Outreach Center (POC) on an annual basis to complete a questionnaire about the occurrence of AESI, as defined in the Outcome Measure section.

The questionnaire will be completed directly by the participant (via a secure web based platform) or will be administered via telephone by a POC staff member. In the event of the occurrence of a AESI, study participant will be encouraged to contact the POC as soon as possible, rather than wait for the annual questionnaire completion. Follow up data is inclusive of the 1 year in the core trial, 4 years in the long term follow up trial and 10 years in this long term safety follow up. Participation for United Kingdom participants will be life-long.

Adverse events (AEs) will be coded using Medical Dictionary for Regulatory Activities (MedDRA). Participant self-reported via an annual questionnaire of adverse events that are ophthalmologic, neurologic, infectious or hematologic.

Number of new diagnoses of an immune-mediated disorderUp to 15 Years

Any new diagnosis of an immune-mediated disorder will be participant self-reported via an annual questionnaire.

Incidents of new cancer, irrespective of prior historyUp to 15 Years

Any new cancer, irrespective of prior history, will be participant self-reported via an annual questionnaire.

Number of reported pregnancy outcome(s)Up to 15 Years

Occurrence of pregnancy outcomes will be participant self-reported via an annual questionnaire

Incidents of ectopic tissue (RPE or non-RPE) formationUp to 15 Years

Occurrence of ectopic tissue (retinal pigment epithelial \[RPE\] or non-RPE) will be participant self-reported via an annual questionnaire

Number of participant reported pregnancies or pregnancy of participant's partnerUp to 15 Years

Occurrence of pregnancy will be participant self-reported via an annual questionnaire

All cause deathUp to 15 Years

All causes of death will be collected via an annual questionnaire (through participant-designated secondary contacts)
