Malignant Ovarian Clear Cell Tumor, Recurrent Ovarian Carcinoma
Conditions
Brief summary
This phase II trial studies how well pembrolizumab and epacadostat work in treating patients with ovarian clear cell carcinoma that has come back (recurrent), remains despite treatment (persistent), or is growing, spreading, or getting worse (progressive). 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. Epacadostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and epacadostat may work better compared to usual treatment (surgery, radiation, or cytotoxic chemotherapy) in treating patients with ovarian clear cell carcinoma.
Detailed description
PRIMARY OBJECTIVE: I. To assess the objective tumor response (proportion of objective response by Response Evaluation Criteria in Solid Tumors \[RECIST\] 1.1 criteria) of the combination of pembrolizumab (MK-3475 \[pembrolizumab\]) and epacadostat in patients with recurrent or persistent clear cell carcinoma of the ovary. SECONDARY OBJECTIVES: I. To determine the nature and degree of toxicity of MK-3475 (pembrolizumab) + epacadostat as assessed by Common Terminology Criteria for Adverse Events (CTCAE) in patients with recurrent or persistent clear cell carcinoma of the ovary. II. To estimate the progression-free survival (PFS) and overall survival (OS) in patients treated with combination of MK-3475 (pembrolizumab) and epacadostat. EXPLORATORY TRANSLATIONAL OBJECTIVES: I. Determine whether the ratio of plasma tryptophan to kynurenine (T:K) correlates with response to MK-3475 (pembrolizumab) + epacadostat, by evaluating plasma T:K pre-treatment, during treatment, and at disease progression. II. Determine whether the presence of PD-L1, IDO-1, tumor-infiltrating regulatory T cells (Tregs), CD8 tumor-infiltrating lymphocytes (TILs), and human leukocyte antigen (HLA) class I in the tumor microenvironment at baseline correlates with objective response to MK-3475 (pembrolizumab) + epacadostat. III. Determine whether soluble PD-L1 (sPD-L1) levels in plasma are correlated with response to MK-3475 (pembrolizumab) + epacadostat, by evaluating sPD-L1 concentrations pre-treatment, during treatment, and at disease progression. OUTLINE: Patients receive epacadostat orally (PO) twice daily (BID) and pembrolizumab intravenously (IV) over 30 minutes once every 3 weeks (Q3W). Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years, then every 6 months for 3 years, and annually thereafter.

Histologic confirmation of the original primary tumor is required via the pathology report. The percentage of clear cell histomorphology must be documented in the pathology report or in an addendum to the original report. If slides of the primary tumor are not available for review due to disposal of slides by the histology laboratory (typically 10 years after diagnosis), a biopsy of the recurrent or persistent tumor is required to confirm at least 50% clear cell histomorphology, as long as tumor is located in an area deemed safe to biopsy. The percentage of clear cell involvement must be documented in the pathology report or in an addendum to the original report * All patents must have measurable disease, and at least one target lesion to be used to assess response as defined by RECIST 1.1. Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded). Each lesion must be \>= 10 mm when measured by computed tomography (CT), magnetic resonance imaging (MRI) or caliper measurement by clinical exam; or \>= 20 mm when measured by chest x-ray.

Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile, who have had a hysterectomy and/or bilateral oophorectomy) do not require contraception * The patient or a legally authorized representative must provide study-specific informed consent prior to study entry
Exclusion criteria
* Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years * Patients who have had prior therapy with MK-3475 (pembrolizumab) or epacadostat or with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or immune check point pathways * History of severe hypersensitivity reaction to any monoclonal antibody * Patients with active auto-immune disease or history of autoimmune disease that might recur, which may affect vital organ function or require immune suppressive treatment including systemic corticosteroids, should be excluded. These include but are not limited to patients with a history of immune related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain-Barre syndrome, myasthenia gravis; systemic autoimmune disease such as systemic lupus erythematosus (SLE), connective tissue diseases, scleroderma, inflammatory bowel disease, Crohn's, ulcerative colitis, hepatitis; and patients with a history of toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or phospholipid syndrome should be excluded because of the risk of recurrence or exacerbation of disease. Patients with vitiligo, endocrine deficiencies including thyroiditis managed with replacement hormones including physiologic corticosteroids are eligible. Patients with rheumatoid arthritis and other arthropathies, Sjogren's syndrome and psoriasis controlled with topical medication and patients with positive serology, such as antinuclear antibodies (ANA), anti-thyroid antibodies should be evaluated for the presence of target organ involvement and potential need for systemic treatment but should otherwise be eligible * Patients with uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure and unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements * Patients with history or evidence upon physical examination of central nervous system (CNS) disease, including primary brain tumor, seizures which are not controlled with non-enzyme inducing anticonvulsants, and/or epidural disease, or history of cerebrovascular accident (CVA, stroke), transient ischemic attack (TIA) or subarachnoid hemorrhage within six months prior to the first date of study treatment.

Concomitant use of monoamine oxidase inhibitors or SSRIs with epacadostat (INCB024360) is prohibited * Patients who have had evidence of active or acute diverticulitis, intra-abdominal abscess, abdominal/pelvic fistula, gastrointestinal perforation, gastrointestinal (GI) obstruction and/or who require parenteral hydration and/or nutrition * Epacadostat (INCB024360) is a substrate of CYP3A4, CYP1A2, CYP2C19, UGT1A9, P-gp, and BCRP. Use caution when administered with strong inhibitors/inducers of these isoenzymes and transporter proteins. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference * History or presence of an abnormal electrocardiography (ECG) that, in the investigator's opinion, is clinically meaningful. Screening QTc interval \> 480 milliseconds is excluded (corrected by Fridericia). In the event that a single QTc is \> 480 milliseconds, the subject may enroll if the average QTc for the 3 ECGs is \< 480 milliseconds. For subjects with an intraventricular conduction delay (QRS interval \> 120 msec), the JTc interval may be used in place of the QTc with sponsor approval. The JTc must be \< 340 milliseconds if JTc is used in place of QTc. Subjects with left bundle branch block are excluded * Patients who are pregnant or nursing
