December 18, 2025 – Life sciences-focused search firm Slone Partners has assisted in the recruitment of Jeffrey S. Kasten as chief business officer of Vertero Therapeutics, a clinical-stage biotechnology company breaking barriers in neurodegenerative disease treatment. “Jeffrey Kasten brings a deep and diversified business development and strategic management skill set to Vertero as the company expands its portfolio of therapies designed to help physicians better manage neurodegenerative diseases and help patients live longer, more productive lives,” said Sona Stroud, senior vice president, executive search, and partner at Slone Partners. “He will be an excellent addition to the company’s leadership team and a valuable partner in its efforts to develop new partnerships and execute successful new product rollouts.”
“I am thrilled to welcome Jeff to the Vertero team,” said Stewart Campbell, CEO of Vertero. “His strategic acumen and track record of successfully cultivating partnerships and advancing pipeline growth are impressive and highly relevant to our mission. Jeff is not only a great cultural addition to our team, he also brings an important perspective to help sharpen our strategic development focus as we work to make an impact on patients and their families affected by neurodegenerative diseases.”
Mr. Kasten brings more than two decades of experience in the life sciences industry spanning corporate strategy, portfolio strategy, and business development across leading biopharmaceutical organizations. Prior to Vertero, he served as vice president of corporate/portfolio strategy and business development at Sage Therapeutics, where he helped shape enterprise strategy, optimize portfolio decisions, and advance key external growth initiatives.
Before Sage, he spent 11 years at Biogen in senior commercial and strategic marketing roles, providing commercial leadership across early- and late-stage pipeline assets and steering commercial assessments that informed key business development initiatives. Mr. Kasten began his career at Bain & Company, where he advised clients across a wide range of industries including biopharma, with time allocated to the Bain Private Equity Group. He later joined Putnam Associates to focus exclusively on strategic consulting projects in biopharmaceuticals, deepening his expertise in commercial and portfolio strategy.
In his new role with Vertero, Mr. Kasten is responsible for driving business development, strategic partnerships, corporate and portfolio strategy, and commercialization planning. His leadership will support the advancement of the company’s pipeline focused on neurodegenerative diseases, with its lead program for Parkinson’s disease, VT-5006, now in a Phase 1 clinical study.
“This is a perfect time to join Vertero as it launches its first-in-human clinical studies for what could be a groundbreaking therapy for neurodegenerative diseases,” said Mr. Kasten. “Vertero’s approach is truly innovative. While I have worked with many drugs that treat the symptoms of neurological diseases, I am excited to advance a program that could profoundly modify the trajectory of the disease. I look forward to working with this talented team of dedicated professionals whose expertise is matched only by their passion to deliver transformational therapies to patients with urgent unmet needs.”
