Frequently asked questions about vudalimab

What is vudalimab used for?

Vudalimab is an investigational monoclonal antibody being studied in oncology for metastatic castration-resistant prostate cancer and ovarian cancer, including clear cell carcinoma. It is also being evaluated in other advanced gynecologic and genitourinary malignancies such as endometrial cancer and cervical carcinoma. It is not approved for any indication.

What does vudalimab target?

Vudalimab targets PD-1 and CTLA-4, two immune checkpoint proteins. By binding both targets, it is designed to enhance T-cell activation against tumor cells. This dual-targeting approach is intended to improve anti-tumor immune responses compared with single-checkpoint blockade.

Who is developing vudalimab?

Vudalimab is being developed by Xencor, Inc., which trades on the Nasdaq under the ticker XNCR. Xencor is a clinical-stage biopharmaceutical company focused on engineered antibodies for cancer and autoimmune diseases.

What phase is vudalimab in?

Vudalimab is in Phase 2 clinical development. It is an investigational agent and has not been approved by the FDA for any indication. The Phase 2 program includes studies in metastatic castration-resistant prostate cancer and selected advanced gynecologic and genitourinary malignancies.

What clinical trials is vudalimab in?

Vudalimab has been studied in two Phase 2 trials. NCT05032040 is an active, not recruiting study in advanced gynecologic and genitourinary malignancies, including ovarian, endometrial, cervical, and prostate cancers, with 170 patients enrolled. NCT05005728 is a completed Phase 2 trial in metastatic castration-resistant prostate cancer that enrolled 72 patients.
