ABT-199 & Ibrutinib in Mantle Cell Lymphoma (AIM)

• Status: Unknown status
• Trial end date: 2018-06-01
• Target enrollment: 0
• Participant gender: All

Summary

This research will test the combination of two new drugs, called ibrutinib and ABT199, taken together in the treatment of Mantle Cell Lymphoma. Other studies have indicated the potential for these drugs to be used in the treatment of participants with Mantle Cell Lymphoma. In this study, the investigators will test the combination of the two drugs together, in order to determine what effects (good and bad) it has on mantle cell lymphoma.

This study has two phases. The first phase is the Primary Evaluation Phase and will closely monitor the effects of ibrutinib and ABT199 for a period of 13 months. Participants who complete 13 months of treatment and continue benefiting from the study treatments will be allowed to continue both drugs until progression or intolerance in the Continuation Phase. The purpose of this phase is to provide patients with continuing access to both ibrutinib and ABT199. Patients will receive routine care from clinician, who will record any sideeffects that may be experienced.

This is one of the first trials in the world to study the combination of ibrutinib and ABT199 together. Therefore the effectiveness of the combination of the study drugs will be assessed, as will how they affect mantle cell lymphoma and how it develops resistance to the treatments. The investigators also do not know whether combining the two drugs together will cause unexpected side effects. Therefore, the study will monitor patients closely and perform scans, blood tests, bone marrow biopsies and other tests at regular intervals.

Criteria

Inclusion Criteria:

1. Subject must be >/= 18 years of age.

2. Subject must have a confirmed diagnosis of Mantle Cell Lymphoma (MCL) according to WHO (2008) criteria, and have received at least one prior line of systemic therapy for MCL.

3. Subject requires treatment in the opinion of the investigator, and has at least one site of radiographically assessable disease not previously irradiated (lymph node with largest diameter >/= 1.5cm, or unequivocal hepatomegaly / splenomegaly)

4. Subject has an Eastern Cooperative Oncology Group (ECOG) performance score of

5. Subject must have adequate bone marrow function at Screening as follows:

• Absolute Neutrophil Count (ANC) >/= 1.0 x 109/L (neutropenia due to marrow infiltration may be supported by growth factors);

• Platelets >/= 50 x 109/L (entry platelet count must be independent of transfusion within 7 days).

6. Subject must have adequate coagulation, renal, and hepatic function, per laboratory reference range at Screening as follows:

• aPTT and PT not to exceed 1.5 × the upper limit of normal (ULN);

• Serum creatinine not to exceed 2 x ULN, and a calculated creatinine clearance of at least 50 mL/min using the Cockcroft-Gault equation or a 24-hour urine collection;

• AST or ALTBilirubinbilirubin > 1.5 × ULN.

7. Female subjects of childbearing potential and non-sterile male subjects (with partners of child bearing potential) must practice at least one of the following methods of birth control with partner(s) from initial study drug administration to 90 days after the last dose of study drug:

• Total abstinence from sexual intercourse as the preferred life style of the subject; periodic abstinence is not acceptable;

• Surgically sterile partner(s); acceptable sterility surgeries are: vasectomy, bilateral tubal ligation, bilateral oophorectomy or hysterectomy;

• Intrauterine device (IUD);

• Double-barrier method (contraceptive sponge, diaphragm or cervical cap with spermicidal jellies or cream AND a condom);

• Hormonal contraceptives (oral, parenteral or transdermal) for at least 3 months prior to study drug administration.

8. Female subjects of childbearing potential must have a negative serum (beta-human chorionic gonadotropin [B-hCG]) or urine pregnancy test at Screening. Women who are pregnant or breastfeeding are ineligible for this study

9. Male subjects must agree to refrain from sperm donation, from initial study drug administration until 90 days after the last dose of study drug.

10. Subject is able to swallow whole tablets.

11. Subject (or their legally-acceptable representatives) must sign an informed consent document indicating that they understand the purpose of and procedures required for the study, including biomarkers, and are willing to participate in the study.

Exclusion Criteria:

1. Subject has undergone an allogeneic stem cell transplant within the last 6 months or currently has active graft-vs-host disease requiring the use of immunosuppressants.

2. Subject has active and uncontrolled autoimmune cytopenias (for 2 weeks), including autoimmune hemolytic anemia (AIHA) and immune thrombocytopenic purpura (ITP).

3. Subject has known central nervous system involvement by MCL.

4. Subject previously participated in an ibrutinib clinical trial or subject previously received a Bruton's tyrosine kinase (BTK) inhibitor other than ibrutinib

5. Subject has received the following within 30 days prior to the first dose of study drug:
