This trial is a Phase I/II study in which a combination of duvelisib and nivolumab will be used to treat a total of patients diagnosed with advanced unresectable melanoma who have progressed on anti-PD1 therapy. The Recommended Phase II Dose of oral duvelisib will be determined and administered with intravenous nivolumab 480mg for up to 1 year or until the patient's disease does not progress or the patient experiences unacceptable side effects to treatment.


This trial will study of PI3Kγδ inhibitor duvelisib in combination with nivolumab in patients with advanced unresectable melanoma who have progressed on anti-PD1 therapy. In the Phase I part of the study (18) patients will be administered nivolumab 480mg intravenously and duvelisib orally in doses from 15mg once a day to 25mg twice a day to determine the recommended dose for the Phase II part of the study. In the Phase II study patients will be administered nivolumab 480mg intravenously and duvelisib orally (dose not determined until the Phase 1 study is completed) up to 1 year as long as their disease doesn't progress or have unacceptable side effects to the study drugs. This trial will attempt to determine whether duvelisib acts as an immunomodulator, to shift the TME from an immunosuppressive to an immunostimulatory setting, to overcome acquired resistance in anti-PD1 treated patients. The phase I portion of the study is uniquely designed to find the ideal dose of duvelisib as an immunomodulator, which is suspected to be lower than the previously determined maximum tolerated dose (MTD) of duvelisib in lymphoma studies.

Inclusion Criteria

AJCC 8th edition criteria for unresectable stage IIIB, stage IIIC, stage IIID or stage IV melanoma who have received at least 3 months of prior treatment with an anti-PD1 or anti-PDL1 antibody and who have progressed on this treatment. Patients who have received a combination anti-PD1 and anti-CTLA4 therapy who exhibit progression at this interval are also permitted. There are no restrictions regarding time since last anti-PD1 treatment, or number of therapies after anti-PD1

AST/ALT ≤2.5x ULN in subjects with liver metastasis, must be within normal limits for those without liver metastasis
Creatinine < 1.5 mg/dL
For patients with actionable BRAF mutations, treatment with BRAF and MEK inhibitors
prior to initiation on trial is recommended, unless patients are intolerant of
therapy or choose not to pursue BRAF targeted therapy
Patients must have measurable disease, defined as at least one tumor lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as ≥10mm with CT scan, MRI or by calipers if documented on clinical exam. If patients have a single lesion, the lesion must be amenable to biopsy without interfering with radiographic assessment as determined by one of the co-PIs
WCBP defined as a sexually mature woman who as not undergone surgical sterilization or who has not been naturally postmenopausal for at least 12 consecutive months for women >55 years of age
Duvelisib and nivolumab therapy may be harmful for a developing fetus. Women of child bearing potential (WCBP) must have a negative urine or serum β human chorionic gonadotropin (βhCG) pregnancy test within 7 days before starting treatment. WCBP and men must agree to use highly effective contraception (pharmacologic birth control, barrier methods or abstinence) prior to study entry and for the duration of study participation through 5 months after the last dose of study medication. Should a woman become pregnant while she or her partner are participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use highly effective contraception prior to the study, for the duration of study participation and 12 weeks following the last dose
Ability to understand and the willingness to sign a written informed consent document
