Clinical Trial Summary

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.

Description:

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.

Intervention

Drug:
• Nivolumab
Nivolumab is a human IgG4 monoclonal antibody that blocks PD-1. It is a type of immunotherapy and works as a checkpoint inhibitor, blocking a signal that prevents activation of T cells from attacking the cancer.
• Duvelisib
Duvelisib is a potent inhibitor of both ? and d isoforms. Duvelisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Type	Measure	Description	Time frame	Safety issue
Other	Immune Cell Function	Evaluation of peripheral blood mononuclear cells (PBMCs) using CyTek flow cytometry.	Baseline (prior to treatment), at 12 weeks after start of treatment; Up to 2 years (cohort)
Other	Immune Cell Function	Evaluation of tumor-infiltrating cells from using CyTek flow cytometry.	Baseline (prior to treatment), at 12 weeks after start of treatment; Up to 2 years (cohort)
Other	Tumor Microenvironment (TME)	Changes in the immune cell population using Vectra imaging.	Baseline (prior to treatment), at 12 weeks after start of treatment; Up to 2 years (cohort)
Other	Mechanism of anti-PD1 Resistance	Changes in gene expression in the tumor using Nanostring gene profiling.	Baseline (prior to treatment), at 12 weeks after start of treatment; Up to 2 years (cohort)
Primary	MTD / Recommended Phase II dose (RP2D) of duvelisib with nivolumab	The Maximun Tolerated Dose / RP2D will be determined via specified 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), which will be considered for decisions to continue enrollment at the current dose level or proceed to the next dose level. Toxicities occurring from day 29 through 28 days after completion of treatment will be considered late toxicities. Acute and late toxicities will be considered when deciding on the RP2D. The highest dose level (Maximum Tolerated Dose) at which = 1 of 6 treated patients experiences a DLT will determine the RP2D. DLTs are defined using National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.	Up to 56 days (per patient)
Primary	Overall Response Rate (ORR)	Complete response [CR] + partial response [PR], per RECIST v1.1 criteria. Per RECIST v1.1, CR: Disappearance of all target lesions. Any pathological lymph nodes(whether target or non-target) must have reduction in short axis to <10 mm. For non-target lesions: Disappearance of all non-target lesions and normalization of tumormarker level. All lymph nodes must be non-pathological in size (<10mm short axis);PR: At least a 30% decrease in the sum of diameters of target lesions, taking asreference the baseline sum diameters.	Up to 36 months
Primary	Change in CD +8 TIL frequency	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.	At baseline and 12 weeks
Secondary	Percentage of Adverse Events at least possibly related to treatment	Acute (within 28 days after start of treatment) and late toxicities (29 to 56 days post start of treatment) rates occurring within 56 days of start of treatment, as graded by CTCAE v5.0 in patients at each dosing interval and in the expansion cohort. Toxicity events include those that are possibly, probably or definitely related to study treatment per Criteria for Adverse Events version 5 (CTCAE v5.0).	Up to 56 days
Secondary	Clinical Benefit	Complete response [CR] + partial response [PR] + stable disease [SD], per RECIST v1.1 criteria . Per RECIST v1.1, CR: Disappearance of all target lesions. Any pathological lymph nodes(whether target or non-target) must have reduction in short axis to <10 mm. For non-target lesions: Disappearance of all non-target lesions and normalization of tumor marker level. All lymph nodes must be non-pathological in size (<10mm short axis);PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters; SD: Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study.	Up to 36 months
Secondary	Duration of Response	The (median) length of time from which measurement criteria are first met for Complete Response (CR) or Partial Response (PR) until the first time at which progressive disease is objectively documented per RECIST v1.1. CR: Disappearance of all target lesions. Any pathological lymph nodes(whether target or non-target) must have reduction in short axis to <10 mm. For non-target lesions: Disappearance of all non-target lesions and normalization of tumormarker level. All lymph nodes must be non-pathological in size (<10mm short axis);PR: At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.	Up to 36 months
Secondary	Progression-free Survival (PFS)	The (median) length of time from the initial date of treatment to the date of documented progression, or the date of death due to any cause (in the absence of progression, whichever occurs first), with progression defined by RECIST v1.1. PerRECIST v1.1, progressive disease is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5mm. For non-target lesions, PD: Unequivocal progression of existing non-target lesions. The appearance of one or more new lesions is also considered progression.	Up to 36 months
Secondary	Overall Survival (OS)	The (median) length of time from the start of treatment that patients remain alive, until death from any cause.	Up to 5 years
Secondary	Adverse events graded by CTCAE v5.0	Percentage of toxicity events that are possibly, probably or definitely related to study treatment per Criteria for Adverse Events version 5 (CTCAE v5.0).	Up to 39 months
