What are the key players in the Geographic Atrophy treatment market?

Overview of Geographic Atrophy Geographic Atrophy (GA)) is the advanced, atrophic form of dry age‐related macular degeneration (AMD) that results in progressive loss of retinal pigment epithelium (RPE), photoreceptors, and choriocapillaris. Seen as well‐demarcated atrophic lesions in the retina, GA leads to irreversible central vision loss when the fovea is eventually involved. Despite being largely asymptomatic in its early stages, GA has a profound impact on patients’ quality of life once the lesions enlarge.

Definition and Pathophysiology
GA is defined clinically by the presence of discrete areas of RPE atrophy, often first appearing in the perifoveal region and eventually coalescing as the disease progresses. Histologically, GA is characterized by the absence of photoreceptors and thinning or loss of RPE cell layers, along with abnormalities in Bruch’s membrane and the choriocapillaris circulation. In recent years, research has established that chronic inflammation and complement cascade dysregulation are central to its pathophysiology. Elevated levels of complement activation products have been measured both in plasma and in ocular tissues, implicating complement factors such as C3 and C5 in mediating gradual retinal degeneration. In addition, genetic predispositions such as variants in complement pathway regulators further support the mechanism of complement hyperactivation in GA progression. Overall, these findings have provided a rationale for targeting the complement cascade in therapeutic strategies, while ongoing research is delving into mitochondrial dysfunction, apoptosis mediators, and extracellular matrix remodeling as potential contributing pathways.

Current Treatment Landscape
Historically, there have been no approved treatments for GA, leaving a significant unmet medical need for patients. In contrast to neovascular AMD (nAMD), where anti‐VEGF therapies have dramatically altered visual outcomes, the treatment of GA has lagged behind until very recently. Advances in late‐stage clinical trials now provide hope, with intravitreal complement inhibitors emerging as the frontrunners. The recent positive outcomes from phase 3 trials – for instance, the DERBY and OAKS trials for pegcetacoplan and the GATHER trials for avacincaptad pegol – indicate that these agents can slow lesion growth by approximately 14–22%. Nonetheless, while these treatments have shown efficacy in reducing anatomical progression, they presently do not improve visual acuity; rather, their benefit lies in retarding the progression of atrophy, which in the long term may help preserve functional vision and the quality of life. As new therapies advance toward regulatory approvals and potential commercialization (with pegcetacoplan already achieving FDA approval in the US as Syfovre), the treatment landscape for GA is rapidly evolving.
