We are a clinical-stage biopharmaceutical company seeking to bring life into balance for patients suffering with Graves’ disease (GD) and thyroid eye disease (TED). We are led by a team with extensive experience in scientific innovation, clinical development and company building, and have a deep history of developing innovative treatments with the potential to make a significant impact on patients’ lives.
Current treatments for GD and TED are very limited, and the ones available are associated with serious side effects that may restrict benefits or have long-term health impacts. Yarrow is developing YB-101, a potentially first-in-class inhibitor of the thyroid stimulating hormone receptor (TSHR), which directly disrupts the central autoimmune mechanism responsible for GD and TED. By directly binding to TSHR and protecting this receptor from autoantibody attack, YB-101 offers the potential to address both thyroidal and extra-thyroidal manifestations of these diseases without the risk of serious toxicities or immunosuppression, thereby delivering rapid, predictable control of these devastating autoimmune conditions.

At Alumis, our goal is to significantly improve the lives of patients by replacing broad immunosuppression with targeted therapies.
We recognize that patients living with immune-mediated diseases need alternatives to currently available therapies. Despite recent advances and innovations in the treatment of immune-mediated diseases, many patients continue to suffer, cycling through currently approved therapies while looking for a solution that alleviates the debilitating impact of their disease without life-limiting side effects.
Addressing the needs of these patients is why we exist. We are pioneering a precision approach that leverages insights we derive from powerful data analytics to select the right target, right molecule, right indication, right patient, and right endpoint resulting in optimized outcomes for patients. We believe that combining our insights with an integrated approach to drug development will produce the next generation of treatments to address immune dysfunction.
Incubated by Foresite Labs, Alumis is led by a team of deeply experienced professionals who are devoted to transforming the lives of patients with immune-mediated diseases by developing a pipeline of transformative therapies.

Arrakis has a simple but powerful vision: To extend small-molecule medicines into new realms of biology, unlocking that biology for medicine. Our approach builds on the existing sophisticated drug discovery toolkit developed for protein targets, which we are adapting and refocusing on discovering small-molecule compounds that act directly on RNA.
We are pioneering new territory, with an expedition led by a team of skilled scientists and drug development leaders who are inventive yet pragmatic. We are on a bold and exciting mission, a mission not without peril, but we have an energized, collaborative, creative and fearless team – a team that has consistently breached barriers and blazed new trails in search of solutions. We are now poised to realize the promise of bringing RNA into play for small-molecule drug discovery.
Pushing the frontier of this emerging field of science is gratifying, but our mission goes beyond the thrill of scientific discovery. We believe that by targeting RNA biology in new ways, we have the potential to impact millions of patients. Our platform will allow us to reach hundreds of biological targets not currently accessible to medicine, including known targets previously considered “undruggable.” Our destination is powerful new therapies for patients everywhere, by opening up a new path for discovering RNA-targeted medicines.
