Our purpose

Our mission is to develop biomarker driven technologies that bring tumor biology into platinum treatment decisions, improving the precision of cancer therapy.

Our Approach

At CHOSA, we develop gene expression–based biomarkers that identify patients most likely to benefit from platinum-based therapies. By integrating tumor biology into clinical decision-making, our technologies support more precise use of standard treatments.

Our Vision

We are working toward a a future where cancer treatment is guided by tumor biology, enabling therapies to be matched to the patients most likely to benefit.

We are driven by our core values

Meet the team advancing precision oncology

Our team is dedicated to advancing cancer care with compassion, innovation, and expertise. Each member of our team brings specialized knowledge and a shared commitment to improving patient outcomes and supporting our partners in oncology.

CHOSA well established management team, both sitting and standing

Achieving this vision requires collaboration across the oncology ecosystem.

We invite organizations across the oncology ecosystem , including pharmaceutical, diagnostic, and biosimilar innovators, to join us in advancing treatments guided by scientific evidence and a shared commitment to improving patient care.
