Study of IPI-145 in Combination With Rituximab or Bendamustine/Rituximab in Hematologic Malignancies

Completed · Phase 1

Conditions studied: Lymphoma, Chronic Lymphocytic Leukemia, Non-Hodgkin Lymphoma, T-cell Lymphoma

In brief

The goal of this study is to characterize the safety, maximum tolerated dose (MTD) and preliminary efficacy profile of IPI-145 given in combination with rituximab, or bendamustine plus rituximab, to subjects with select relapsed/refractory hematologic malignancies.

Dose Expansion Phase
Arm 1 Cohort A: Limited to subjects with CD-20 positive CLL with at least one prior anticancer treatment.
Arm 1 Cohort B: Limited to subjects with diagnosis of CD-20 positive NHL with at least one prior anticancer treatment.
Arm 2 Cohort A: Limited to subjects with CD-20 positive CLL with at least one prior anticancer treatment.
Arm 2 Cohort B: Limited to subjects with diagnosis of CD-20 positive NHL with at least one prior anticancer treatment.
Disease status requirement:

Eastern Cooperative Oncology Group (ECOG) Performance Status score of ≤2.
Subject must have measurable disease using the disease-specific response criteria for NHL or CLL
Age ≥ 18 years.
Subject has recovered from all clinically significant toxicities related to prior antineoplastic therapies with the exception of alopecia and bone marrow and organ functions.

You may not qualify if…

Prior allogeneic hematopoietic stem cell transplant (HSCT).
Prior autologous transplant or radioimmunotherapy ≤6 months prior to the first dose of trial treatment.
Subject has a high grade lymphoma such as Burkitt's, lymphoblastic or small non-cleaved cell lymphomas. Subjects with intermediate grade lymphoma (such as diffuse large B-cell lymphoma) are eligible.
Subjects with diffuse B-cell lymphoma must either not be eligible for autologous bone marrow transplant (BMT) or relapsed after autologous BMT.
More than three previous cytotoxic chemotherapy regimens for subjects treated on the arm containing bendamustine.
Subjects who have had a severe allergic or anaphylactic reaction to any humanized or murine monoclonal antibodies.
Chemotherapy, cancer immunosuppressive therapy, growth factors (except erythropoietin), radiation therapy (other than whole brain irradiation [WBI]) surgery or ablative therapy or investigational drugs/devices ≤28 days before first dose of trial treatment.
Subjects receiving high doses of corticosteroids must have been tapered to a stable dose at least 7 days before the first dose of trial treatment.
Tyrosine kinase inhibitor within 7 days prior to the first dose of trial treatment.
Subjects with overt leptomeningeal leukemia or central nervous system (CNS) lymphoma. Subjects must be free of CNS disease for a minimum of 2 months. Subjects with symptoms of CNS disease must have a negative diagnostic lumbar puncture prior to study enrollment.
Subjects with a history of stroke, unstable angina, myocardial infarction, or ventricular arrhythmia requiring medication or mechanical control within the last 6 months.
Baseline QTcF >480 ms. Note: This criterion does not apply to subjects with a left bundle branch block.
Subjects who have had a venous thromboembolic event requiring anticoagulation and who meet any of the following criteria:
Have been on a stable dose of anticoagulation for <1 month.
Have had a Grade 2, 3 or 4 hemorrhages in the last 30 days.
Are experiencing continued symptoms for their venous thromboembolic event.
Subjects with a history of liver disease as a result of alcohol abuse, chronic hepatitis, or other chronic liver disease (other than metastatic disease to the liver).
Subjects with positive HBsAg, HBcAb or HCV are excluded.
Subjects with a history of tuberculosis within the preceding two years.
Prior surgery affecting drug absorption or any gastrointestinal dysfunction that could alter drug absorption.
Subjects with a known hypersensitivity to bendamustine or rituximab.
Presence of active infection within 72 hours of treatment. Subjects with ongoing use of prophylactic antibiotics are eligible as long as there is no evidence of active infection and the antibiotic is not included on the list of prohibited medications.
