Bendamustine, Obinutuzumab, and Venetoclax in Patients With Untreated Mantle Cell Lymphoma
Study Details
Study Description
Brief Summary
This phase II trial studies how well bendamustine, obinutuzumab, and venetoclax work in treating patients with mantle cell lymphoma. Drugs used in chemotherapy, such as bendamustine and venetoclax, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving bendamustine, obinutuzumab, and venetoclax may work better in treating patients with mantle cell lymphoma.

Detailed Description
PRIMARY OBJECTIVE:
- To evaluate the efficacy of the combination of bendamustine, obinutuzumab and venetoclax in patients with untreated mantle cell lymphoma.
SECONDARY OBJECTIVES:
-
To evaluate the safety and dose intensity of the combination of bendamustine, obinutuzumab and venetoclax in untreated mantle cell lymphoma.
-
To explore methods of determining molecular remission for patients with untreated mantle cell lymphoma (MCL).
-
To evaluate long-term outcomes including progression-free and overall survival for patients with untreated MCL who receive the combination.
OUTLINE:
Patients receive venetoclax orally (PO) on days 1-28 of course 1 and days 1-10 of subsequent courses, bendamustine intravenously (IV) on days 1 and 2, and obinutuzumab IV on days 1, 8, and 15 of course 1 and day 1 of subsequent courses. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unaccepted toxicity.
After completion of study treatment, patients are followed up at 45-60 days.

Outcome Measures
Primary Outcome Measures
- Rate of complete response at completion of induction therapy with this combination [Up to 2.5 years from study start]
Response will be assessed by positron emission tomography (PET)/computerized tomography (CT) imaging according to the Lugano Classification for response assessment in lymphoma, developed at the 2014 International Conference on Malignant Lymphoma.
Secondary Outcome Measures
- Rate of minimal residual disease (MRD) negative complete response by ClonoSEQ mantle cell lymphoma (MCL) assay [Up to 7 years from study start]
MRD will be assessed by peripheral blood using the ClonoSEQ assay available from Adaptive Biotechnologies.
- Overall response rate [Up to 7 years from study start]
Will be summarized descriptively.
- Time to tumor progression [Up to 7 years from study start]
Will be summarized descriptively.
- Progression free survival (PFS) [Up to 7 years from study start]
Will be described using the Kaplan-Meier methodology. Some patients may undergo consolidative autologous stem cell transplant without evidence of disease progression. This will not be counted against PFS.
- Overall survival [Up to 7 years from study start]
Will be described using the Kaplan-Meier methodology.
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Signed informed consent form
-
Ability and willingness to comply with the requirements of the study protocol
-
Histologic diagnosis of mantle cell lymphoma. This diagnosis must be confirmed at the treating center and patients must have this diagnosis confirmed by at least one of the following criteria:
-
Fluorescent in situ hybridization (FISH) or conventional cytogenetics positive for t(11;14)
-
Cyclin D1 positive by immunohistochemistry
-
Documentation by a hematopathologist at the treating institution that there is pathologic evidence of mantle cell lymphoma if neither criteria above are met
-
No previous therapy for diagnosis of lymphoma (note that in patients deemed to be high-risk for tumor lysis syndrome or for rapid clinical deterioration due to symptomatic disease by the investigator, a short course of steroids designed to decrease tumor burden is permitted)
-
Eastern Cooperative Oncology Group performance status of 0, 1, or 2
-
Hemoglobin ≥ 9 g/dL
-
Absolute neutrophil count ≥ 1.5 x 10⁹/L
-
Platelet count ≥ 75 x 10⁹/L
-
Serum creatinine ≤ 2.0 mg/dL or creatinine clearance ≥ 40 mL/min
-
Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) ≤ 2.5 x upper limit of normal (ULN)
-
Total bilirubin < 1.5 x ULN (or ≤ 3 x ULN for patients with documented Gilbert syndrome)
-
NOTE: Patients with renal or hepatic impairment that is disease-related (ie, hydronephrosis, hepatic involvement) in the opinion of the investigator but who meet all other eligibility criteria may be considered for enrollment in consultation with the investigational new drug (IND) sponsor, Dr. Jonathon Cohen. Documentation of prior adequate renal/hepatic function and clear association with the disease will be required
-
For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use a contraceptive method with a failure rate of < 1% per year during the treatment period and for at least 30 days after the last dose of venetoclax or 18 months after the last dose of obinutuzumab, whichever is longer
-
A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus)
-
Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices
-
The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception
-
For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below:
-
With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period and for at least 6 months after the last dose of obinutuzumab. Men must refrain from donating sperm during this same period
-
With pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 6 months after the last dose of obinutuzumab to avoid exposing the embryo
-
The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception
