Phase II, Single Arm, Open Label Multi-center Study of Obinutuzumab and Ibrutinib in the Front Line Treatment of Indolent Non-Hodgkin's Lymphomas

This phase II trial studies how well obinutuzumab and ibrutinib work as front line therapy in
treating patients with indolent non-Hodgkin's lymphoma. Monoclonal antibodies, such as
obinutuzumab, may interfere with the ability of cancer cells to grow and spread. Ibrutinib
may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Giving obinutuzumab and ibrutinib may work better in treating patients with non-Hodgkin's
lymphomas.

PRIMARY OBJECTIVES:

I. To assess the efficacy of the combination of ibrutinib and obinutuzumab in chemotherapy
naive patients with indolent lymphomas.

SECONDARY OBJECTIVES:

I. To assess progression free survival rates and overall survival rates in indolent
lymphomas.

II. To assess safety and tolerability of the combination. III. To evaluate response using
positron emission tomography (PET) and correlate PET negativity with durability of response.

Inclusion Criteria:

- • Previously untreated, histologically confirmed indolent non-Hodgkin's lymphoma as
follows:

- Follicular lymphoma (World Health Organization [WHO] classification grade 1, 2,
or 3a)

- Marginal zone lymphoma including:

- Nodal and splenic marginal zone lymphoma (MZL) who have an indication for
systemic therapy

- Extranodal MZL:

- Nongastric/noncutaneous MZL requiring systemic therapy

- Cutaneous MZL will be eligible only if they have pathologically
confirmed extra-cutaneous disease

- Gastric MZL only if stage IIIE/IV defined as lymph node involvement on
both sides of the diaphragm or with disseminated extranodal disease
such as bone marrow or additional extra nodal sites

- Pathological diagnosis should be obtained by incisional or
excisional tissue biopsy; core biopsy is permissible if obtaining
an incisional or excisional is not possible and if the grade can
be assessed on the core biopsy. A core biopsy can also be used if
deemed in the best interest of the patient in the opinion of the
investigator

- Patients must have stage II-IV disease

- All patients should have measurable disease; measurable disease is
defined as a lymph node or tumor mass that is >= 1.5 cm in at
least one dimension by computed tomography (CT) or the CT portion
of the PET/CT

- Documentation of CD20+ status

- Patients must have an indication for therapy per standard modified
Groupe d'Etude des Lymphomes Folliculaires (GELF) criteria
including:

- Symptoms attributable to lymphoma, threatened end-organ function, cytopenia
secondary to lymphoma, bulky disease (defined as: single mass > 7 cm in diameter,
or 3 or more masses > 3 cm in diameter), splenomegaly, and steady progression
over at least 6 months

- Eastern Cooperative Oncology Group (ECOG) performance status 0-2

- Patients must be able to swallow whole pills

- Ability and willingness to comply with the requirements of the study
protocol. When it is determined by the study investigator that a potential
research participant is cognitively impaired, a surrogate consent from a
caregiver or legally-authorized representative will be obtained. Caregiver
or legally-authorized representative will ensure that they comply with the
protocol in order for the subject to be considered eligible.

- Female subjects who are of non-reproductive potential (i.e., post-menopausal
by history - no menses for >= 1 year; OR history of hysterectomy; OR history
of bilateral tubal ligation; OR history of bilateral oophorectomy); female
subjects of childbearing potential must have a negative urine/serum
pregnancy test upon study entry

- Male and female subjects who agree to use both a highly effective method of
birth control (e.g., implants, injectables, combined oral contraceptives,
some intrauterine devices [IUDs], complete abstinence , or sterilized
partner) and a barrier method (e.g., condoms, vaginal ring, sponge, etc)
during the period of therapy; female patients of reproductive potential who
are not surgically sterile must practice adequate birth control for a
minimum of twelve months post-treatment; male patients who are not
surgically sterile must practice adequate birth control for a minimum of
three months post-treatment

- Absolute neutrophil count > 1.5 x 10^9 cells/mm^3

- Platelet count > 50,000 cells/mm^3 (50 x 10^9/L)

- Hemoglobin > 9.0 g/dL

- Serum aspartate transaminase or alanine transaminase =< 3.0 x upper limit of
normal (ULN)

- Prothrombin time (PT)/international normalized ratio (INR) < 1.5 x ULN and
activated partial thromboplastin time (aPTT) < 1.5 x ULN (unless
abnormalities are unrelated to coagulopathy or bleeding disorder)

- Estimated creatinine clearance >= 30 ml/min (calculated according using
Cockcroft-Gault formula)

- Bilirubin =< 1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome
or of non-hepatic origin)

- Patients with Child Pugh B or C liver failure will be excluded

Exclusion Criteria:

- Prior history of malignancies unless the patient has been disease free for >= 5 years;
exceptions include basal cell carcinoma or squamous cell carcinoma of the skin;
carcinoma in situ of cervix; carcinoma in situ of breast, localized prostate cancer,
or superficial bladder cancer that has undergone curative therapy

- Prior therapy for lymphoma including chemotherapy or immunotherapy including
ibrutinib/anti-CD20 agents; patient may have received corticosteroids, but should be
off them 2 weeks prior to study entry; known prior significant hypersensitivity to
obinutuzumab (not including infusion reactions) or ibrutinib

- Patients with evidence of large B cell transformation (transformed disease) are not
eligible.

- Known central nervous system (CNS) involvement by lymphoma

- Known bleeding disorders (e.g., von Willebrand's disease or hemophilia)

- Concomitant use of warfarin or other vitamin K antagonists

- Requires treatment with a strong cytochrome P450 (CYP) 3A inhibitor

- Known active bacterial, viral, fungal, mycobacterial, or other infection (excluding
fungal infections of nail beds) or any major episode of infection requiring treatment
with IV antibiotics or hospitalization (related to the completion of the course of

DNA maybe considered for participation, but must agree to receive appropriate

hepatitis B DNA monitored every 4 weeks with real-time polymerase chain reaction
(PCR) by the treating physician; these patients should be referred to a
