简要总结
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.
详细描述
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.

结局指标
主要结局
DLTs by Phase I Dose of Duvelisib With Nivolumab
时间窗: Up to 56 days (per patient)
Number of patients experiencing acute dose limiting toxicities (DLTs) and laboratory abnormalities considered possibly related to study treatment, occurring from the initial dose of duvelisib + nivolumab through day 28 of treatment (acute) or toxicities occurring from day 29 through 28 days after completion of treatment (late toxicities). DLTs are defined using National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
Best Overall Response
时间窗: Up to 29 months
Best Response per RECIST v1.1: Completed Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Disappearance of all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (\<10mm short axis); Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters; Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for Progressive Disease (PD), taking as reference the smallest sum diameters while on study. Progressive Disease (PD): ≥20% (relative) increase in sum of diameters of target lesions referencing smallest sum on study (includes baseline sum if is smallest on study) and, the sum must also demonstrate an absolute increase of at least 5 mm; appearance of one or more new lesions.
Best Overall Response Rate (ORR)
时间窗: Up to 29 months
Proportion of patients with a Best Response (CR+PR)/(CR+PR+SD+PD) per RECIST v1.1 of Completed Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Disappearance of all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (\<10mm short axis); or Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.
Change in CD 8+ TIL Frequency
时间窗: Week 4 to Week 12
CyTek flow cytometry will be used to evaluate tumor-infiltrating cells in PBMCs and tumor tissue for the increased frequency (proliferation) and activation of CD8+ TILs. Proliferation of CD8+ TIL cells correlate with improved survival in patients with melanoma.
