Blumenkranz, M.D., M.M.S., to its board of directors. Dr. Blumenkranz, a renowned retinal surgeon and biotechnology entrepreneur, brings more than four decades of clinical, scientific and corporate leadership experience advancing innovative therapies for retinal disease. The Company also announced that Muneer Satter will step down from the board after more than 11 years of distinguished service and steadfast support as a director and investor. “We are delighted to welcome Mark to our board of directors as Annexon enters its next phase of growth, advancing two late-stage clinical programs with potential to help millions of patients worldwide,” said Douglas Love, president and chief executive officer of Annexon. “Mark's unique combination of retinal expertise, biotechnology leadership, and experience building successful companies will provide tremendous strategic value as we advance vonaprument in geographic atrophy and prepare for commercialization. Mr. Love continued, “We are also deeply grateful to Muneer for his many years of service, strategic guidance and unwavering support since joining our Board in 2015. As a trusted advisor and investor with strong conviction in our platform, Muneer played an instrumental role in the company’s evolution from a preclinical stage organization into a public biotechnology company clinically advancing a robust late-stage pipeline for neuroinflammatory diseases. We thank Muneer for his many contributions and wish him continued success in his future endeavors.” Dr. Blumenkranz added, “Annexon's C1q-targeted platform approach is uniquely positioned to help patients across a range of neuroinflammatory diseases and importantly, represents a differentiated path forward for patients with geographic atrophy, a disease that has lacked a truly vision-sparing treatment option. I look forward to working with the board and the management team as vonaprument advances toward pivotal Phase 3 data and potential registration.” Mark S. Blumenkranz, M.D., M.M.S., is the H.J. Smead Professor Emeritus of Ophthalmology at Stanford University School of Medicine and Co-Director of Stanford's Ophthalmic Innovation Program. An internationally recognized retinal specialist, surgeon, entrepreneur and innovator, Dr. Blumenkranz previously served as Chair of Stanford's Department of Ophthalmology and founding Director of the Byers Eye Institute at Stanford. Throughout his distinguished career, he has helped pioneer advances in retinal surgery, drug delivery, ophthalmic imaging and gene therapy, while authoring more than 175 peer-reviewed publications and holding numerous patents. He has co-founded and led numerous ophthalmic and life sciences companies through development, commercialization and successful acquisition, including Adverum Biotechnologies, where he served as co-founder and chairman of the board; Optimedica Corporation, which was acquired by Abbott Medical Optics; Oculeve, which was acquired by Allergan; and Kedalion Therapeutics, where he served as founding chairman and chief executive officer until its acquisition by Novartis. He was also a founder and director of Verana Health. Dr. Blumenkranz currently serves as Managing Director of Lagunita Biosciences and sits on the boards of several ophthalmic and life sciences companies.
