About Us

We are a small, tightly knit team of medical researchers committed to improving the lives of patients. Our team brings experience across academia, biotech and large pharma, combining the strengths and learnings from each environment.

We are data-driven and focused on finding the most efficient path to advance our molecules into the clinic. Members of our core team previously helped drive two novel drugs into clinical trials in less than three years at Inflazome.

We are also an inclusive, multinational team committed to empowering gender equity and fostering a collaborative, high-performing culture.

We are dedicated to applying our deep understanding of inflammation to develop new treatments for autoimmune and inflammatory diseases. Patients are our primary motivation, and our team brings together scientific expertise, industry experience and clinical trial know-how to advance ground-breaking medicines for debilitating diseases.
