Summary

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.

Objectives

PRIMARY OBJECTIVE:
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).

SECONDARY OBJECTIVES:
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.

EXPLORATORY OBJECTIVES:
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 or days 1-14 and nivolumab intravenously (IV) over 30 minutes on day 1 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo positron emission tomography (PET)-computed tomography (CT) or CT scan at baseline. Patients also undergo punch biopsy and collection of blood samples throughout the trial.

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

Eligibility

1. 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
2. Patients must have had at least one line of prior systemic therapy
3. 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
4. Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 50%)
5. Absolute neutrophil count >= 1000/mcL
6. Platelets > 75,000/mcL
7. Total bilirubin =< 1.5 x institutional upper limit of normal (ULN) or =< 5 x institutional ULN if with history of Gilbert’s syndrome
8. Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 3 x institutional ULN
9. Creatinine =< 2.0 x institutional ULN
10. Patients with treated brain metastases are eligible if follow-up brain imaging after central nervous system (CNS)-directed therapy shows no evidence of progression
11. 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
12. 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 nivolumab and duvelisib. 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 and duvelisib. 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
13. 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
14. 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
15. Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial
