Zanzalintinib for Advanced Urothelial Carcinoma Progressing After Prior Therapy

Starting soon · Phase 2

Conditions studied: Advanced Urothelial Carcinoma

In brief

This is a Phase II, single arm study. All subjects will receive Zanzalintinib 60 mg orally once daily until progression per RECIST 1.1 or intolerable toxicities or patient/investigator decision to discontinue study therapy. Radiology imaging will be performed every 8 weeks for 3 timepoints then every 12 weeks thereafter. A window of ± 7 days may be applied to all study visits to accommodate observed holidays, inclement weather, scheduling conflicts etc.

Males able to father a child who are sexually active with a female of childbearing potential must be willing to abstain from penile-vaginal intercourse or use an effective method(s) of contraception.
• Subjects with known HIV-infection or acquired immunodeficiency syndrome (AIDS)-related illness on stable anti-retroviral therapy with a CD4+ T cell count ≥ 200/µL and undetectable viral load are eligible for this trial. NOTE: To be eligible, participants taking CYP inhibitors (eg, zidovudine, ritonavir, cobicistat, didanosine) or CYP3 inducers (efavirenz) must change to a different regimen not including these drugs 7 days prior to registration. Anti-retroviral therapies (ART) must have been received for at least 28 days prior to registration.
• Subjects with a known chronic hepatitis B virus (HBV) infection, must have an undetectable HBV viral load on suppressive therapy, if indicated. Subjects with a history of hepatitis C virus (HCV) infection must have been treated and cured. For subjects with HCV infection who are currently on treatment, the HCV viral load must be undetectable to be eligible for this trial.
