Graybug Vision, Inc. announced the last patient visit in its GB-102 Phase 2b ALTISSIMO core trial (the 12-month treatment phase) in wet age-related macular degeneration (wet AMD). ALTISSIMO 12-month topline data are expected to be announced in the second quarter of 2021, with full results to be presented at a medical conference later in the year. Of the 56 patients enrolled in ALTISSIMO, 50 patients completed the 12-month treatment phase, while the remaining six patients withdrew for reasons unrelated to their treatment. Furthermore, 58% of patients who completed their Month 12 visit were eligible and agreed to continue clinical monitoring in a six-month extension of the trial. The goal of this six-month extension period is to observe further durability of GB-102 in wet AMD patients. Graybug’s lead product candidate, GB-102, is a proprietary microparticle depot formulation of the pan-vascular endothelial growth factor (pan-VEGF) inhibitor, sunitinib malate, designed to be administered intravitreally twice per year. GB-102 seeks to reduce the need for frequent intravitreal injections by expanding treatment duration to six months, and potentially longer, thus reducing the burden of current anti-VEGF treatments which require up to 12 injections per year. ALTISSIMO comprises a 12-month, multicenter, prospective, masked, randomized trial comparing GB-102 administered every six months to aflibercept administered every two months in patients with anti-VEGF-responsive wet AMD, followed by an additional six-month observational period. The objective of the ALTISSIMO Phase 2b core trial is to assess the safety, tolerability, and pharmacodynamic profile of GB-102. The findings will inform the design of Graybug’s pivotal Phase 3 clinical trial program in wet AMD expected to initiate in the second half of 2021.
