Study Description

Brief Summary

This phase I/II trial studies the side effects and best dose of ixazomib citrate, gemcitabine hydrochloride, and doxorubicin hydrochloride when given together in treating patients with urothelial cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery. Ixazomib citrate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Chemotherapy drugs, such as gemcitabine hydrochloride and doxorubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ixazomib citrate together with gemcitabine hydrochloride and doxorubicin hydrochloride may be a better treatment for urothelial cancer.

Condition or Disease Intervention/Treatment Phase
  • Drug: Doxorubicin Hydrochloride
  • Drug: Gemcitabine Hydrochloride
  • Drug: Ixazomib Citrate
Phase 1/Phase 2

Detailed Description

  1. Find maximum tolerated doses (MTDs) for the combination therapy of ixazomib (ixazomib citrate) and gemcitabine (gemcitabine hydrochloride)/doxorubicin (doxorubicin hydrochloride) (i.e. dose pairs of ixazomib and gemcitabine/doxorubicin that have an acceptable target toxicity rate of 30%). (Phase I)
  1. Define the dose-limiting toxicities of the dose pairs found. II. Choose a dose pair for phase II expansion in patients with locally advanced or metastatic urothelial cancer.

  2. Determine the objective response rate and median survival for patients treated on the phase II expansion.

OUTLINE: This is a phase I, dose-escalation study followed by a phase II study.

Patients receive ixazomib citrate orally (PO), gemcitabine hydrochloride intravenously (IV) over 90 minutes, and doxorubicin hydrochloride IV over 15-30 minutes on day 1. Cycles repeat every 14 days in the absence of disease progression or unacceptable toxicity.

    Accepts Healthy Volunteers:
    Inclusion Criteria:
    • All patients must have histologic demonstration of metastatic or locally unresectable transitional cell carcinoma of the urothelium; variant histology is allowed as long as there is an urothelial component present; the principal investigator (PI), will serve as the final arbiter of eligibility

    • All patients must have measurable or evaluable disease; in general, liver and lung lesions should be at least 1 cm, and patients with node-only disease should have lesions of >= 1.5 cm in greatest dimension; patients with disease confined to bone may be eligible if a measurable lytic defect is present or a serum marker is elevated (> 4 x upper limit of normal [ULN]); the principal investigator is the final arbiter in questions related to measurability; patients with a three-dimensional mass or pelvic sidewall fixation on bladder examination under anesthesia are considered to have measurable disease

    • Patients must have had at least one prior therapy to be eligible for either phase I or II, unless they are either not candidates for or refuse cisplatin-based therapy

    • Phase I: patients are eligible with any number of prior regimens regardless of what those regimens contained (i.e. prior bortezomib or combination gemcitabine and adriamycin is acceptable)

    • Phase II: patients are eligible if their previous chemotherapy regimen did not contain bortezomib, carfilzomib, or other known proteasome inhibitor or a combination of gemcitabine >= 800 mg/m2 plus adriamycin >= 30 mg/m2; patients who receive sequential or alternating therapy as part of front-line treatment will be counted as having one prior regimen; patients who have failed prior neoadjuvant chemotherapy will be eligible for this trial

    • If prior history of ischemic heart disease or exposure to 200 mg/m^2 of doxorubicin, patients must have a measured ejection fraction (either by multigated acquisition scan [MUGA], echocardiogram [ECHO], stress test, or ventriculography) of at least 45%
