About Octave Bioscience

Octave Bioscience, Inc. operates as a commercial-stage precision medicine company, directing its focus on shifting the treatment paradigm for multiple sclerosis (MS) and other neurodegenerative diseases. Founded in 2014 by William Hagstrom and Melinda Thomas, the company is headquartered in Menlo Park, California. Hagstrom, who served as the founding CEO and now acts as Chairman of the Board, has an extensive background in the biotechnology sector, previously leading companies like Crescendo Bioscience, a firm specializing in rheumatology diagnostics. This experience in creating measurement tools for complex diseases directly informs Octave's mission.

Read full description

The company's core offering is the Octave Precision Care Solution, an integrated platform designed to provide a more comprehensive and objective view of a patient's MS. This solution is multi-modal, combining three key components: a proprietary blood test, enhanced MRI analytics, and a digital platform for patient monitoring. The flagship product is the Multiple Sclerosis Disease Activity (MSDA) Test, which analyzes a custom panel of 18 to 20 protein biomarkers from a blood sample to quantify the level of disease activity. This test provides a more dynamic and nuanced assessment than traditional methods, which often rely on subjective symptom evaluation and periodic MRI scans. The platform also includes enhanced MRI analytics and a clinical care program that tracks patients and connects them with MS nurse practitioners in real-time.

Octave's business model targets a wide array of stakeholders within the healthcare ecosystem, including neurologists, payers, and pharmaceutical companies. The company generates revenue by providing these tools and insights to facilitate more informed and personalized treatment decisions. The MSDA test, for instance, is used by hundreds of neurologists and is covered by several health plans. The solution is commercially available and utilized in prominent MS Centers of Excellence, academic institutions, and independent clinics across the United States. Having raised approximately $120 million in total funding from investors like Novartis, Merck, and The Blue Venture Fund, Octave is well-capitalized to continue its commercial expansion. The company is also leveraging its expertise to develop a similar biomarker panel for Parkinson's disease, supported by a $10 million grant from The Michael J. Fox Foundation.
