I. Best overall response of complete response/partial response (CR/PR).
I. Toxicity defined as any adverse event (AE) grade 3 and higher. II. Progression free survival.
I. Gene expression profiling using Lymph5Cx test. II. Sequencing using the ion torrent platform (76 gene panel for known mutations in lymphoma).
III. Sequencing of BTK and phospholipase-C gamma (PLC) to evaluate for mutations.
IV. Minimal residual disease testing (MRD by flow cytometry and targeted sequencing post treatment).
Patients receive obinutuzumab intravenously (IV) over 30 minutes on days 1, 8, and 15 of cycle 1, and day 1 of cycles 2-6. Patients also receive ibrutinib orally (PO) once daily (QD) on days 1-28. Treatment repeats every 28 days for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients achieving partial response (PR) continue to receive obinutuzumab IV every 2 months and ibrutinib PO QD for up to 2 years in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 6 months for up to 3 years.

Experimental: Treatment (obinutuzumab and ibrutinib)
Patients receive obinutuzumab IV over 30 minutes on days 1, 8, and 15 of cycle 1, and day 1 of cycles 2-6. Patients also receive ibrutinib PO QD on days 1-28. Treatment repeats every 28 days for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients who have PR continue to receive obinutuzumab IV every 2 months and ibrutinib PO QD for 2 years in the absence of disease progression or unacceptable toxicity.
- Percent of Participants With Best Overall Objective Response or Complete Response/Partial Response (CR/PR) [ Time Frame: From first dose of study therapy until the 6-month disease assessment (Cycle 6, Day1 or End of Induction Day 28). Disease assessment is also assessed at end of Cycle 2 (2-months). ]Overall response is measured combining bone marrow biopsy with CT or PET, measuring target and evaluable non-targeted lesions, according to the Lugano criteria. For FDG-PET, the Deauville criteria is used in conjecture with CT to assess lesion FDG-update. Deauville scale ranges from 1 to 5, where 1 is best (no uptake or no residual uptake) and 5 is worst (markedly increased uptake or any new lesion). If bone marrow is involved prior to treatment, infiltrate must have cleared on repeat biopsy for CR; bone marrow assessment is irrelevant for determination of PR. Measurements are taken at baseline, end of cycle 2, end of induction (after cycle 6) and every 4 months thereafter. Best overall response is any CR or PR reported since start of therapy. Percent of participants with complete response or partial response (CR+PR) are reported along with 95% confidence interval.
- Progression Free Survival (PFS) [ Time Frame: Time from the first day of combined study treatment to disease progression or death, whichever occurs first, assessed up to approximately 4 years, 11 months, after first dose of study drug(s) ]Median progression free survival is measured from first day of study therapy until disease progression or death, whichever comes first. Participants who progress prior to their first scheduled disease assessment are considered to have clinically progressed. Participants who do not progress are censored at the time of their last disease assessment. The Kaplan-Meier method is used to estimate median PFS. 95% confidence interval is provided, although upper limit was not achieved (insufficient number of progressions)
- Number of Participants With Treatment-related Toxicities, Grade 3 or Higher, as Assessed by CTCAE v4.0 [ Time Frame: Measured from the first dose of either study drug until 30 days after the last dose of study drug, for approximately 4 years, 11 months. ]Defined as any adverse event grade 3 or higher, classified according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0, from the first dose of study drug(s) until 30 days after the last dose of study drug(s)

Subjects must have a diagnosis of relapsed or refractory mantle cell lymphoma as follows:
- Diagnosis of mantle cell lymphoma (MCL) must include morphology and expression of either cyclin D1 in association with other relevant markers (eg, CD19, CD20, CD5) or evidence of t(11;14) as assessed by cytogenetics, fluorescent in situ hybridization (FISH), or polymerase chain reaction (PCR)
Relapsed or refractory disease is defined as no response or progressive disease to prior treatment if the prior treatment comprised any of the following:
- 1 regimen containing an anti-CD20 antibody administered for >= 2 doses, and/or
- >= 1 regimen containing 1 cytotoxic agent (e.g., bendamustine, chlorambucil, cyclophosphamide, cytarabine, doxorubicin) administered for 2 cycles
- At least 1 measurable site of disease according to Revised Response Criteria for Malignant Lymphoma (Cheson Criteria); the site of disease must be greater than 1.5 cm in the long axis regardless of short axis measurement or greater than 1.0 cm in the short axis regardless of long axis measurement, and clearly measurable in 2 perpendicular dimensions
