Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | NT-501 CNTF-releasing Implant Events ≤ 6 Months Post-implant | Participants received an ocular implantation of a NT-501 CNTF-releasing capsule (20 ng/day) in one eye (the study eye) at baseline. The events listed reflect the primary outcome endpoint of adverse events reported within 6 months post-implantation. | 1 | 5 | EG000 |
| Group 2 | NT-501 CNTF-releasing Implant Events > 6 Months Post-implant | Participants received an ocular implantation of a NT-501 CNTF-releasing capsule (20 ng/day) in one eye (the study eye) at baseline. The events listed are adverse events reported after the primary outcome endpoint of 6 months post-implantation. | 1 | 5 | EG001 |
