PRIMARY OBJECTIVES:
I. To assess the clinical benefit of nivolumab in T-cell lymphomas, as measured by objective
response rate (ORR) within 12 cycles according to the Lugano Classification Response Criteria
(2014).
SECONDARY OBJECTIVES:
I. To assess safety and tolerability of the regimen in this patient population. II. To assess
progression-free survival (PFS). III. To assess duration of response (DOR). IV. To assess
overall survival (OS).
TERTIARY OBJECTIVES:
I. To evaluate T-cell/cytokine profile in the peripheral blood - peripheral blood specimens
will be used to assess T-cell activation and cytokine up regulation as measures of treatment
effect.
II. To evaluate intratumoral biomarkers- intratumoral cell populations and distribution,
genetic variability, mutational burden and T-cell activation will be evaluated to identify
potential biomarkers that correlate with response to therapy.
III. To assess the potential association between PD-L1/PD-1/PD-L2 expression on tumor and
T-cells and/or PD-L1 soluble levels in plasma with clinical efficacy of PD-1 blockade.
OUTLINE:
Patients receive nivolumab intravenously (IV) over 60 minutes on day 1. Treatment repeats
every 14 days for up to 8 courses in the absence of disease progression or unacceptable
toxicity. Patients achieving stable disease, complete response, or partial response receive
nivolumab IV over 60 minutes on day 1 of course 9. Treatment repeats every 28 days for up to
24 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 35 days, 100-120 days,
230-250 days, and 330-390 days.

persons of childbearing potential only Note: Persons of child-bearing potential
(POCBP) must use appropriate method(s) of contraception; POCBP should use an adequate
method to avoid pregnancy for 23 weeks (30 days plus the time required for nivolumab
to undergo five half-lives) after the last dose of investigational drug; men who are
sexually active with POCBP must use any contraceptive method with a failure rate of
less than 1% per year; men receiving nivolumab and who are sexually active with POCBP
will be instructed to adhere to contraception for a period of 31 weeks after the last
dose of investigational product; persons who are not of childbearing potential (ie,
who are postmenopausal or surgically sterile) as well as azoospermic men do not
require contraception; should a person become pregnant or suspect being pregnant while
participating in this study, the person should inform the treating physician
immediately

phase of the study
- Willing to provide tissue and blood samples for correlative research purposes
Exclusion Criteria:
- All primary cutaneous T-cell lymphomas
- Any of the following:
- Pregnant women
- Nursing women
- Men or women of childbearing potential who are unwilling to employ adequate
contraception
- Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment
of the investigator, would make the patient inappropriate for entry into this study or
interfere significantly with the proper assessment of safety and toxicity of the
prescribed regimens
- Active, known or suspected autoimmune disease Note: subjects are permitted to enroll
if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to
autoimmune condition only requiring hormone replacement, psoriasis not requiring
systemic treatment
- Use of systemic treatment with either corticosteroids (>10 mg daily prednisone
equivalents) or other immunosuppressive medications < 14 days of registration Note:
inhaled or topical steroids are permitted; > 10 mg daily prednisone equivalents are
