About
This phase II trial studies how well pembrolizumab and interferon gamma-1b work in treating patients with stage IB-IVB mycosis fungoides and Sezary syndrome that has come back (relapsed) or has not responded to previous treatment (refractory). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Interferon gamma-1b may boost the immune system activity. Giving pembrolizumab and interferon gamma-1b together may work better in treating patients with stage IB-IVB mycosis fungoides and Sezary syndrome.
Full description
PRIMARY OBJECTIVES:
I. To assess the overall response rate (ORR) of MK-3475 (pembrolizumab) and interferon gamma-1b (IFN-G) (Actimmune) combination immunotherapy in subjects with previously treated mycosis fungoides or Sezary syndrome. (Treatment Group 1) II. To determine whether the combination of interferon gamma-1b (ACTIMMUNE) and MK-3475 (pembrolizumab) improves the ORR of pembrolizumab in patients with unresectable or metastatic synovial sarcoma. (Treatment Group 2)
SECONDARY OBJECTIVES:
I. To explore the safety/tolerability and clinical activity of MK-3475 (pembrolizumab) and IFN-G (Actimmune) in subjects with previously treated mycosis fungoides or Sezary syndrome with respect to (Treatment Group 1):
Ia. Safety and tolerability. Ib. Time to response (TTR). Ic. Duration of response (DOR). Id. Progression-free survival (PFS). Ie. Event-free survival (EFS). If. Percentage of all patients who have a response duration of at least 12 months (ORR12).
II. To determine the progression-free survival (PFS) and overall survival (OS) for patients with advanced synovial sarcoma receiving interferon gamma-1b and MK-3475 (pembrolizumab). (Treatment Group 2) III. To determine the tolerability of the combination of interferon gamma-1b and MK-3475 (pembrolizumab) based on Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. (Treatment Group 2)
EXPLORATORY OBJECTIVES:
I. To investigate the relationship between the following putative biomarkers for combination immunotherapy of MK-3475 pembrolizumab) and IFN-gamma (Actimmune) and clinical outcomes (as measured by safety/tolerability and ORR, DOR, PFS, EFS) in subjects with previously treated mycosis fungoides or Sezary syndrome, including tumor/microenvironment (PD-1/PD-L1/PD-L2 expression, cytotoxic T lymphocyte [CTL]s, regulatory T cell [Treg]s, macrophages, dendritic cell [DC]s; nanostring gene expression profile), systemic immune response (flow cytometry, mass cytometry [CyTOF], Luminex multiplexed cytokine profile), and molecular/genomic immune correlates (exome sequencing, high throughput sequencing [HTS] for T cell receptor [TCR]). (Treatment Group 1)
II. To investigate paired, serial biopsy specimens from pre-treatment and 8-12 weeks after starting treatment for the following (Treatment Group 2):
IIa. MHC class I expression (scored by pathologist). IIb. Number of infiltrating T cells per mm^2. IIc. Tumor associated macrophage number and phenotype using multiplex immunohistochemistry.
IId. T cell clonality. IIe. Gene expression profiling.
III. To investigate peripheral blood samples from patients to determine (Treatment Group 2):
IIIa. The number and phenotype of T cells specific for computed tomography (CT) antigens and potential neo-antigens.
IIb. The phenotype and activation state of circulating monocytes and peripheral blood mononuclear cell (PBMC).
IIc. Cytokines associated with response.
OUTLINE: Patients are assigned to 1 of 2 groups.
GROUP I: Patients with Mycosis Fungoides and Sezary Syndrome receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Cycles repeat every 3 weeks for up to 2 years in the absence of disease progression or unexpected toxicity. Patients also receive interferon gamma-1b subcutaneously (SC) 3 times per week for 12 weeks, and then follow 3 weeks on and 3 weeks off schedule for up to 2 years in the absence of disease progression or unexpected toxicity.
GROUP II: Patients with advanced synovial sarcoma receive pembrolizumab IV over 30 minutes on day 1 and interferon gamma-1b SC once a week. Cycles repeat every 3 weeks for up to 2 years in the absence of disease progression or unexpected toxicity.
After completion of study treatment, patients are followed up for 30 days and then every 12 weeks for up to 1 year.

-
Patients who have had chemotherapy or targeted small molecule therapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) before entering the study

-
Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2
-
Patients who have received an investigational agent or have used an investigational device within 4 weeks of the first dose of study drug
-
Has a history of a well-characterized and defined immune deficiency before the diagnosis of mycosis fungoides or Sezary syndrome or is receiving systemic steroid therapy greater than 10 mg/day of prednisone or equivalent within 4 weeks or any other form of immunosuppressive therapy within 7 days before the first dose of trial treatment
-
Has had a prior monoclonal antibody within 4 weeks before study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from AEs due to agents administered more than 4 weeks earlier

-
Has a known additional malignancy that is progressing or requires active treatment; exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin that has undergone potentially curative therapy, or in situ cervical cancer
-
Patients with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events; patients with carcinomatous meningitis should also be excluded; patients with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging using the identical imaging modality for each assessment, either magnetic resonance imaging [MRI] or computed tomography [CT] scan, for at least 4 weeks before the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days before trial treatment
-

Has an active autoimmune disease that has required systemic treatment in the past 2 years (i.e., with use of disease modifying agents, corticosteroids, or immunosuppressive drugs); replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment
-
Has a history of (non-infectious) pneumonitis that required steroids or current pneumonitis
-

-
Pregnant women are excluded from this study because MK-3475 (pembrolizumab) is an agent with 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 MK-3475 (pembrolizumab), breastfeeding should be discontinued if the mother is treated with MK-3475 (pembrolizumab); these potential risks may also apply to Interferon-gamma; MK-3475 (pembrolizumab) and Interferon-gamma may have adverse effects on a fetus in utero; furthermore, it is not known if MK-3475 (pembrolizumab) or Interferon-gamma have transient adverse effects on the composition of sperm; patients are excluded from this study if pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening visit through 120 days after the last dose of trial treatment
