PMBCL:
- Diagnosis of PMBCL, according to
the World Health Organization (WHO) classification of neoplasms of the hematopoietic and lymphoid
tissues (WHO Criteria 2008).
- Subject must be able to provide an evaluable core or excisional lymph
node biopsy for evaluation of PMBCL diagnosis from an archival or newly
obtained biopsy at Screening. (Central review is not required before
enrolment. Enrolment can be done on local pathologic review for
diagnosis.)
- Have relapsed or refractory PMBCL and:
* Have relapsed after auto-SCT or have failed to achieve a CR or PR within 60 days of auto-SCT. Subjects may
have received intervening therapy after auto-SCT for relapsed or
refractory disease, in which case they must have relapsed after or be
refractory to their last treatment.
OR
* For subjects who are ineligible for auto-SCT, have received at least = 2
lines of prior therapy and have failed to respond to or relapsed after
their last line of treatment. For subjects who received consolidative
local radiotherapy after systemic therapy, local radiotherapy will not be
considered as a separate line of treatment.
- Must have been previously exposed to rituximab as part of prior lines
of treatment.
Richter Syndrome:
- Pathologic diagnosis per local institutional review of Richter syndrome
that transformed from CLL.
- Have relapsed or refractory RS and has received at
least 1 previous treatment for RS.
All Subjects:
- Have radiographically measureable disease by independent central
review, defined as at least one lesion that can be accurately measured in
at least two dimensions with appropriate anatomic imaging (CT scan or
magnetic resonance imaging [MRI]). Minimum measurement must be > 15 mm in the longest diameter.
a. RS subjects must also be PET positive at screening, defined as having at least one lesion, attributable to malignancy and with appropriate correlation to anatomic imaging, with uptake greater than that of normal liver tissue.
- Must have a performance status of 0 or 1 on the Eastern Cooperative
Oncology Group (ECOG) Performance Scale
- Life expectancy > 3 months
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 90
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 16
- Is currently participating and receiving study therapy or has
participated in a study of an investigational agent and received study
therapy or used an investigational device within 4 weeks of the first
dose of treatment.
- Is receiving systemic steroid therapy < 3 days before the first dose of
trial treatment or receiving any other form of immunosuppressive
medication.
Note:
a. Corticosteroid use on study after Cycle 1 for management of adverse
events, serious adverse events, and events of clinical interest, as a
premedication for IV contrast allergies/reactions, or if considered
necessary for a subject's welfare is allowed.
b. Subjects who receive daily steroid replacement therapy are an
exception. Daily prednisone at doses of 5 to 7.5 mg is an example of replacement therapy.
c. Equivalent hydrocortisone doses are also permitted if administered as
replacement therapy.
- Has had a prior monoclonal antibody within 4 weeks prior to study Day
1 or who has not recovered (i.e. = Grade 1 or at baseline) from adverse
events due to agents administered more than 4 weeks earlier.
- Has had prior chemotherapy or targeted small molecule therapy within
2 weeks prior to study Day 1 or has had prior radiation therapy within 4 weeks prior to study Day 1 or who has not recovered (i.e. = Grade 1 (2 weeks for RS subjects) or
at baseline) from adverse events due to agents administered more than 4 weeks
earlier (2 weeks for RS subjects)..
Exception: Subjects with RS with CLL may receive ibrutinib (or similar
for CLL) up to 24 hours before first dose.
- Has undergone prior allogeneic hematopoietic stem cell transplantation
within the last 5 years. (Subjects who have had a transplant greater
than 5 years ago are eligible as long as there are no symptoms of Graft
versus Host Disease (GVHD).
- Has a known additional malignancy (except underlying CLL for RS) that
is progressing or requires active treatment. Exceptions include basal cell
carcinoma of the skin, squamous cell carcinoma of the skin, or in situ
cervical cancer that has undergone potentially curative therapy.
- Has known active central nervous system (CNS) involvement. Subjects with prior CNS
involvement are eligible if their CNS disease is in radiographic,
cytological (for cerebrospinal fluid disease) and clinical remission.
- Has active autoimmune disease that has required systemic treatment in past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment
- Has a history of (non-infectious) pneumonitis that required steroids, or current pneumonitis.
- Has an active infection requiring intravenous systemic therapy.
- Has received prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways).
- Has a known history of Human Immunodeficiency Virus (HIV 1 and 2 antibodies), or known active
Hepatitis B (Hepatitis B surface antigen reactive), or Hepatitis C (Hepatitis C virus RNA [qualitative] is detected).
- Has received a live vaccine within 30 days prior to first dose.
