Item 8.01 Other Events
GATHER2 Enrollment and Availability of Topline Data
On June 18, 2021, the Company announced that it is expecting to complete patient enrollment for GATHER2, its ongoing Phase 3 clinical trial of Zimura® (avacincaptad pegol) for the treatment of geographic atrophy ("GA") secondary to age-related macular degeneration ("AMD"), in late July of this year. The Company expects top-line data from GATHER2 to become available during the second half of 2022, approximately one year after the enrollment of the last patient plus the time needed for database lock and analysis.

GATHER2 Patient Retention and GATHER1 Patient Retention
The Company also announced that patient retention in GATHER2 is exceeding expectations. The Company is targeting patient retention for the trial, as measured by the injection fidelity rate through month 12, of greater than 90%. The 12-month injection fidelity rate for GATHER1, the Company's completed Phase 3 clinical trial evaluating Zimura for the treatment of GA secondary to AMD, was 87%. The injection fidelity rate is calculated by dividing the total number of actual injections for all patients by the total number of expected injections based on the total number of patients enrolled in the trial.

GATHER1 Post-Hoc Analyses in Drusen and Nascent GA
In addition, the Company also announced results from new post-hoc analyses performed on data from GATHER1. The post-hoc analyses evaluated the progression of drusen and nascent GA, both of which are earlier forms of dry AMD, in patients treated with Zimura 2 mg as compared to patients in the sham group. The data show a 19.6% absolute reduction in the rate of progression from drusen to incomplete Retinal Pigment Epithelial and Outer Retinal Atrophy ("iRORA") or complete Retinal Pigment Epithelial and Outer Retinal Atrophy ("cRORA"), for the Zimura 2 mg group as compared to sham at 18 months, representing a relative risk reduction of 72%. The data also show a 21.8% absolute reduction in the rate of progression from iRORA to cRORA for the Zimura 2 mg group as compared to sham at 18 months, representing a relative risk of reduction of 52%.


The graphs below illustrate the results from these post-hoc analyses:

Proportion of patients that progress from drusen to iRORA or cRORA (Zimura 2 mg compared to sham)

Proportion of patients that progress from iRORA to cRORA (Zimura 2 mg compared to sham)

Based on these results, the Company intends to study Zimura in earlier stages of dry AMD.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
