This phase I trial identifies the best dose, possible benefits, and/or side effects of duvelisib in combination with nivolumab in treating patients with stage IIB-IVB mycosis fungoides and Sezary syndrome. Duvelisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving duvelisib in combination with nivolumab may work better than giving each of these drugs individually, or treating with the usual approach in patients with mycosis fungoides and Sezary syndrome.



I. To determine the recommended phase II dose (RP2D) or maximum tolerated dose (MTD) of the combination of duvelisib with nivolumab in patients with advanced mycosis fungoides/Sezary syndrome (MF/SS).


I. To observe and record anti-tumor activity. Ia. To determine the overall response rate at four months to the combination of nivolumab and duvelisib.

Ib. To determine the time to maximum response, best overall response rate, complete remission rate, and duration of response among responding patients.


I. To evaluate whether intra-patient changes in serum cytokines (soluble CD40L, TNF-beta, IL-17alpha, IL-15, CXCL13, IL-12p40) predict response to duvelisib in combination with nivolumab in cutaneous T-cell lymphoma (CTCL).

II. To explore whether the combination of duvelisib and nivolumab changes the T-cell repertoire including T-cell receptor sequencing pre- and post- treatment with duvelisib and nivolumab in effort to better understand skin flare and other immunogenic reactions to this combination therapy.

OUTLINE: This is a dose-escalation study of duvelisib in combination with fixed dose nivolumab followed by a dose-expansion study.

Patients receive duvelisib orally (PO) once daily (QD) or twice daily (BID) on days 1-28 and nivolumab intravenously (IV) over 30 minutes on day 1. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for 2 years.

Patients must have histologically or cytologically confirmed MF or SS, stages IIB to IVB with measurable disease and/or detectable blood involvement based on the Global Cutaneous Lymphoma Response Criteria
Patients must have had at least one line of prior systemic therapy
Age >= 18 years. Because no dosing or adverse event data are currently available on the use of duvelisib in combination with nivolumab in patients < 18 years of age, children are excluded from this study
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 50%)
Absolute neutrophil count >= 1000/mcL
Platelets > 75,000/mcL
Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) or =< 5 x institutional ULN if with history of Gilbert's syndrome
Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x institutional ULN
Creatinine =< 2.0 x institutional ULN
Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression
Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
The effects of nivolumab and duvelisib on the developing human fetus are unknown. For this reason and because other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential (WOCBP) and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. WOCBP should use an adequate method to avoid pregnancy for 5 months after the last dose of investigational drug. WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [HCG]) within 7 days prior to the start of nivolumab. Women must not be breastfeeding. Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men receiving nivolumab and duvelisib and who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 7 months after the last dose of investigational product. Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men) do not require contraception. WOCBP is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Menopause is defined clinically as 12 months of amenorrhea in a woman over 45 in the absence of other biological or physiological causes. In addition, women under the age of 55 must have a documented serum follicle stimulating hormone (FSH) level less than 40 mIU/mL
Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 7 months after completion of administration of investigational agents on this study
Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity (IDMC) who have a legally-authorized representative (LAR) and/or family member available will also be eligible
Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial

Carriers will be monitored per institutional guidelines
Patients should be excluded if they have known active hepatitis B (e.g. hepatitis B virus [HBV] surface antigen [HBsAg] reactive) or hepatitis C (e.g. hepatitis C virus [HCV] ribonucleic acid [RNA] [qualitative] is detected)
Patients with chronic HBV or HCV are defined as patients with positive hepatitis B serology: Patients with a negative HBsAg and a positive hepatitis B core antibody (HBcAb) require an undetectable/negative hepatitis B deoxyribonucleic acid (DNA) test (e.g. polymerase chain reaction [PCR] test) to be enrolled, and will require prophylactic antiviral treatment initiated prior to the first dose of study drug, and continued until approximately 6 to 12 months after completion of study drug(s)
Patients who are receiving any other investigational agents
History of allergic reactions attributed to compounds of similar chemical or biologic composition to duvelisib or nivolumab
Patients who have not recovered from adverse events due to prior anti-cancer therapy
(i.e., have residual toxicities > grade 1), with the exception of alopecia and
Patients receiving any medications or substances that are strong inhibitors or inducers of CYP3A4 are ineligible to start study therapy. Patients who are on strong inhibitors or inducers of CYP3A4 may start study therapy if discontinued 5 half lives before start of study therapy. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, interstitial lung disease or active, non-infectious pneumonitis, congestive heart failure New York Heart Association (NYHA) grade >= 3, unstable angina pectoris, and cardiac arrhythmia

Note: Criteria does not apply to subjects with a right or left bundle branch block
Patients who have had evidence of active or acute diverticulitis, intra-abdominal abscess, gastrointestinal (GI) obstruction and abdominal carcinomatosis which are known risk factors for bowel perforation should be evaluated for the potential need for additional treatment before coming on study
Pregnant women are excluded from this study because nivolumab has the potential for
teratogenic or abortifacient effects. Because there is an unknown but
potential risk for adverse events in nursing infants secondary to treatment of
the mother with nivolumab, breastfeeding should be discontinued if the mother
is treated with nivolumab. These potential risks may also apply to other
agents used in this study
