Open for Enrollment

Why is this study being done?

The purpose of this study is to determine the maximum tolerated dose (MTD), activity, and safety of oprozomib in patients with hematologic malignancies.

Who is eligible to participate?

INCLUSION CRITERIA: Phase 1b - Histologically confirmed diagnosis of a hematologic malignancy, excluding patients with acute leukemia or MDS. - Relapsed after standard therapy for their malignancy and considered to be an appropriate candidate for a Phase 1 clinical study by their treating physician. Phase 2 - Multiple myeloma with measurable disease - Waldenström macroglobulinemia with symptomatic relapse - Eastern Cooperative Oncology Group (ECOG) Performance Status 0-2. Ethical/Other - Patients must sign a written informed consent form in accordance with federal, local, and institutional guidelines. - Female patients of childbearing potential must have a negative serum or urine pregnancy test and agree to use effective contraception. Male patients must use an effective barrier method of contraception. EXCLUSION CRITERIA: - Chemotherapy with approved or investigational anticancer therapeutics, including steroid therapy intended to treat underlying malignancy, within 3 weeks prior to first dose or 6 weeks for antibody therapy. - Radiation therapy within 3 weeks prior to first dose. Radioimmunotherapy within 8 weeks prior to first dose. Localized radiation therapy within 1 week prior to first dose. - Immunotherapy within 3 weeks prior to first dose (except for antibody therapy, where 6 weeks is required). - Prior stem cell transplant (SCT) therapy (autologous SCT within the prior 8 weeks; allogeneic SCT within the prior 16 weeks). Patients with prior allogeneic SCT should not have evidence of moderate-to-severe graft-vs-host disease (GvHD; as defined in Filipovich 2005). - Evidence of central nervous system (CNS) lymphoma. - Prior treatment with carfilzomib unless in the phase 2. - Major surgery within 3 weeks prior to first dose. - Symptomatic Congestive heart failure, ischemia, conduction abnormalities, or myocardial infarction within 6 months. - Acute active infection requiring systemic antibiotics, antivirals, or antifungals. - Known or suspected human immunodeficiency virus (HIV) infection or patients who are HIV seropositive. - Active hepatitis A, B, or C infection. - Significant neuropathy (Grade 3, Grade 4, or Grade 2 with pain) at the time of the first dose. - Patients with pleural effusions requiring routine thoracentesis or ascites requiring routine paracentesis. - Female patients who are pregnant or lactating.
