A New Type of Medicine

Our investigational lead candidate, azenosertib, has the potential to deliver on the promise of WEE1 inhibition in cancer therapy.

Our pipeline is focused on advancing potential first-in-class WEE1 inhibitor azenosertib as a monotherapy for Cyclin E1-positive platinum-resistant ovarian cancer, our lead indication.

Ongoing Study
Planned Study
Results from pre-clinical and clinical studies support the ongoing development of azenosertib as both a monotherapy and combination agent across a number of oncology indications.

extending potential for azenosertib.

MORE CHOICE. MORE POSSIBILITY.
innovating for patients

We see broad franchise potential for azenosertib across tumor types, including those driven by oncogenes that induce replication stress and those that harbor loss of function of tumor suppressors associated with cell cycle regulation.

Investigators have expressed great interest in further development of azenosertib beyond ovarian cancer due to its orthogonal, complimentary nature to cytotoxic agents, such as chemotherapy, and its ability to selectively target WEE1, a master cell regulator. Zentalis is currently supporting an investigator-sponsored trial and is interested in further development of azenosertib beyond ovarian cancer.
