Phase II Trial of Venetoclax and Rituximab as Initial Therapy in Older Patients With Mantle Cell Lymphoma

Detailed Description
For young, fit patients with mantle cell lymphoma, intensive chemotherapy and rituximab followed by ASCT is often used to achieve prolonged disease free survival. However, this therapy is not curative and has not been shown to improve overall survival. For older or frail patients, who are ineligible for stem cell transplantation, improved disease free survival can be achieved with chemotherapy and rituximab without ASCT, but at the cost of significant short and long-term toxicity. Venetoclax monotherapy has shown impressive single-agent activity in relapsed and refractory mantle cell lymphoma with low rates of adverse events.
The hypothesis is that initial therapy with venetoclax and rituximab will result in rates of CR and PR that are comparable to historical rates with chemoimmunotherapy. Furthermore, this regimen will have fewer side effects than traditional therapy. Investigators also hypothesize that patients achieving a CR will have long durations of response that will continue after stopping venetoclax.
Study investigators will test this hypothesis with an open label, single arm phase II trial with a target accrual of 40 participants. This study will include patients over age 60 who are not candidates for aggressive upfront therapy . Subjects will receive venetoclax and rituximab for up to 12 cycles of 4 weeks each. All patients will stop venetoclax after 12 cycles. Participants who have stable disease or disease progression after 4 cycles will be removed from the trial in order to receive standard of care chemoimmunotherapy. Participants who do not achieve a CR after 8 cycles of venetoclax and rituximab will receive 4 cycles of standard of care bendamustine in addition to continuing rituximab and venetoclax.
This is the first phase II study of venetoclax and rituximab alone as initial therapy for mantle cell lymphoma. In the relapsed and refractory setting, venetoclax has shown high activity in MCL, and as such is a promising option for a non-chemotherapy approach to upfront treatment.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Subjects must have a histologically confirmed diagnosis of mantle cell lymphoma as defined by the World Health Organization (WHO) classification scheme.
- Age ≥ 60
- Subjects must be previously untreated for mantle cell lymphoma and deemed to require treatment by the treating physician
- ECOG performance status of 0-3
Subject must have adequate bone marrow* without growth factor support as follows:
- Absolute Neutrophil Count (ANC) ≥ 1000/μL
- Platelets ≥ 75,000/mm3 (entry platelet count must be independent of transfusion within 14 days of Screening)
- Hemoglobin ≥ 9.0 g/dL * These criteria may be waived by study investigators if there is evidence of bone marrow involvement by MCL that is believed to be the cause of the cytopenias.
Subject must have adequate renal, and hepatic function, per laboratory reference range at screening as follows:
- Subject must have adequate renal, and hepatic function, per laboratory reference range at screening as follows:
- Calculated creatinine clearance ≥ 40 mL/min; determined via the Cockcroft-Gault formula.
AST and ALT ≤ 3.0 × ULN; Bilirubin ≤ 1.5 × ULN*. Subjects with Gilbert's Syndrome may have a bilirubin > 1.5 × ULN
- These criteria may be waived by study investigators if abnormal values believed to be due to lymphoma.
Female subjects must be surgically sterile, postmenopausal (for at least 1 year), or have negative results for a pregnancy test performed as follows:
- At Screening on a serum sample obtained within 14 days prior to the first study drug administration, and
- Prior to dosing on a urine sample obtained on Cycle 1 Day 1 if it has been > 7 days since obtaining the serum pregnancy test results.
All female subjects not surgically sterile or postmenopausal (for at least 1 year) and non-vasectomized male subjects must practice at least 1 of the following methods of birth control:
- Total abstinence from sexual intercourse (minimum 1 complete menstrual cycle);
- A vasectomized partner(s);
- Hormonal contraceptives (oral, parenteral, vaginal ring or transdermal) for at least 3 months prior to study drug administration;
- Double-barrier method (condoms and diaphragm with spermicidal [sponge, jellies or creams]).
- Ability to understand and willingness to sign IRB-approved informed consent
Exclusion Criteria:
- Subject has blastoid-variant mantle cell lymphoma
- Subject requires immediate cytoreduction as determined by study investigators
- Subject has documented CNS involvement of mantle cell lymphoma
- Subject has Ann Arbor stage I or contiguous stage II mantle cell lymphoma
- Subject has an uncontrolled infection
- Subject has HIV infection
- All subjects will be screened for Hepatitis B (HBsAg, anti-HBs, anti-HBc IgM and total) and Hepatitis C (antibody or RNA). Subjects who are positive for Hepatitis B by HBsAg or DNA as well as subjects positive for Hepatitis C will be excluded. Subjects with anti-HBc positivity and DNA negative may be included but will be required to undergo monthly HBV DNA testing and liver function liver function testing (AST, ALT, alkaline phosphatase, total bilirubin). Patients with HCV antibody positivity and HCV pcr negativity are eligible to be included.
- Subject requires the use of warfarin
- Subject has received immunization with live virus vaccine within 28 days prior to the first dose of study drug
- A female subject is pregnant or breast-feeding

Experimental: venetoclax and rituximab in patients over 60 yrs old with previously untreated mantle cell lymphoma
Venetoclax dose escalation for Cycles 1-4.
If Complete response (CR) at Cycle 4, continue with cycles 5-12 at fixed venetoclax 400mg dose.
If partial response (PR) at Cycle 4, continue with cycles 5-8 at fixed venetoclax 800mg dose.
If CR at Cycle 8 after PR, continue with cycles 9-12 at fixed venetoclax 800mg dose.
If continued PR at Cycle 8, reduce venetoclax to 400mg and add bendamustine 90 mg/m2.

Sequential dose levels for Venetoclax dependent on patient response.
Fixed doses of 375 mg/m2 rituximab.

Overall response rate (ORR) after four cycles of venetoclax and rituximab.
Time Frame: 120 days
|
The ORR will be the sum of complete (CR) and partial responses (PR)as determined by PET/CT and Lugano criteria.
Simon's optimal two-stage design will be used to test the null hypothesis that the true ORR is 50% or less (not considered clinically acceptable).
