Iveric Bio Announces Publication of GATHER1 Phase 3 Clinical Trial Results for Zimura® in Geographic Atrophy Secondary to Age-related Macular Degeneration, in Ophthalmology®, the Journal of the American Academy of Ophthalmology
The published article, entitled “C5 Inhibitor Avacincaptad Pegol for Geographic Atrophy Due to Age-Related Macular Degeneration: A Randomized Pivotal Phase 2/3 Trial,” is now available online at https://www.aaojournal.org/article/S0161-6420(20)30845-9/fulltext?dgcid=raven_jbs_aip_email.
“These published data bring Zimura one step closer as a potential treatment for patients with GA secondary to AMD, who currently do not have any treatment options available to them,” said
“We are privileged to have the positive results of the Zimura GATHER1 clinical trial published in Ophthalmology, the highly-respected and peer-review publication of the
“We want to thank all the patients, clinical trial investigators and their staffs for their support and participation in this well conducted trial. We believe these robust, published, Phase 3 clinical data should further increase the enthusiasm for our ongoing GATHER2 clinical trial,” stated
In the Company’s second Phase 3 clinical trial for Zimura in GA secondary to AMD, known as GATHER2, approximately 400 patients will be randomized to receive either monthly administration of Zimura 2 mg or sham during the first 12 months of the trial, at which time the primary efficacy analysis of the mean rate of change of GA growth at 12 months will be performed. At month 12, the Company plans to re-randomize patients in the Zimura 2 mg arm to receive either monthly or every other month administration of Zimura 2 mg. The final evaluation will take place at month 24.
Age-related macular degeneration (AMD) is the major cause of moderate and severe loss of central vision in aging adults, affecting both eyes in the majority of patients. The macula is a small area in the central portion of the retina responsible for central vision. As AMD progresses, the loss of retinal cells and the underlying blood vessels in the macula results in marked thinning and/or atrophy of retinal tissue. Geographic atrophy, the advanced stage of AMD, leads to further irreversible loss of vision in these patients. There are currently no
Complement factor C5 is a central component of the complement cascade and is believed to be involved in the development and progression of AMD. Zimura is designed to inhibit complement factor C5 cleavage into C5a and C5b. By inhibiting the formation of complement C5 terminal fragments, Zimura may decrease the activation of inflammasomes and the formation of membrane attack complex (MAC). This mechanism of action could potentially prevent or slow down the degeneration of retinal pigment epithelial (RPE) cells and slow down the progression of GA.
GATHER1 Clinical Trial
286 patients were enrolled in the GATHER1 clinical trial, with patients receiving Zimura 1 mg, Zimura 2 mg, Zimura 4 mg or a sham injection monthly for 18 months. Efficacy data from patients receiving Zimura 1 mg was not part of the prespecified primary statistical analysis.
There was no Zimura-related inflammation, no Zimura-related discontinuations from the trial, no cases of endophthalmitis and no Zimura-related adverse events reported by investigators in the trial. Through month 18, the investigator reported incidence of choroidal neovascularization (CNV) in the untreated fellow eye was 11 patients (3.8%), and in the study eye was 3 patients (2.7%) in the sham control group, 2 patients (7.7%) in the Zimura 1 mg group, 8 patients (11.9%) in the Zimura 2 mg group, and 13 patients (15.7%) in the Zimura 4 mg group. The most frequently reported ocular adverse events were related to the injection procedure.
