Factors Involved in Anti-VEGF Treatment Decisions for Neovascular Age-Related Macular Degeneration: Insights from Real-World Clinical Practice.

BACKGROUND

Anti-vascular endothelial growth factor (anti-VEGF) agents are widely prescribed for the treatment of neovascular age-related macular degeneration (nAMD). Although studies have investigated patient choice of anti-VEGF agent, little is known regarding factors that influence physician preference of anti-VEGF agent for their patients.

OBJECTIVE

To describe physician rationale and challenges in prescribing anti-VEGF treatments for patients with nAMD.

METHODS

Data were drawn from the Adelphi Real World nAMD Disease Specific Programme™, a cross-sectional survey with retrospective data capture of physicians and their patients with nAMD in the United States between October 2021 and May 2022. Physicians (n = 56) reported data for up to 13 consecutively consulting patients (n = 451), including current anti-VEGF treatments used, factors affecting physicians' choice of anti-VEGF agent and treatment strategy, and restrictions on specific agents.

RESULTS

Most physicians prefer employing a "treat-and-extend" treatment strategy, over "fixed interval" or "pro re nata" strategies. However, in routine clinical practice, "treat-and-extend" was reported for less than half of nAMD-diagnosed eyes. Top factors influencing physician choice of anti-VEGF agent and treatment strategy included maximizing clinical benefit (eg visual acuity gains and fluid control), patient convenience, and reducing out-of-pocket costs. However, physicians also reported facing substantial roadblocks in prescribing their choice of anti-VEGF agent, including restrictions on approved agents and gaps in insurance coverage. Persistent fluid was the most common physician-selected reason for switching a patient away from an anti-VEGF agent.

CONCLUSION

Physicians face barriers to prescribing their preferred anti-VEGF agents in real-world healthcare settings. Overcoming these challenges may improve treatment outcomes for patients with nAMD.
