Pembrolizumab in Ultramutated and Hypermutated Endometrial Cancer
United States25 participantsStarted 2016-09
Plain-language summary
Primary Objectives: To assess the antitumor activity (proportion of objective response by RECIST 1.1 criteria) of pembrolizumab with objective tumor response in patients with persistent, recurrent or metastatic endometrial cancer harboring an ultra-mutated or hyper-mutated (MMR gene-defective) phenotype identified by next generation sequencing (NGS) and comprehensive genomic profiling (CGP). To determine the nature and degree of toxicity of pembrolizumab as assessed by CTCAE in patients with persistent, recurrent or metastatic endometrial carcinoma. Secondary Objective(s): To estimate the duration of progression-free survival (PFS) and overall survival (OS).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Patients must have histologically confirmed endometrial cancer that is recurrent or progressive following at least one prior chemotherapy regimen.
. Patients with the following histologic epithelial cell types are eligible: Endometrioid adenocarcinoma, serous adenocarcinoma, clear cell carcinoma, undifferentiated carcinoma, mixed epithelial carcinoma, carcinosarcoma, and adenocarcinoma not otherwise specified (N.O.S.).
. Tumors must demonstrate ultramutation (POLE/POLD1-mutation) and/or hyper-mutation (due to MMR gene defect) in a representative primary or metastatic tumor site by next generation sequencing (NGS) and Comprehensive Genomic Profiling (CGP) testing, and/or standard PCR-based DNA microsatellite instability (MSI) and immunohistochemistry (IHC).
. All patients must have measurable disease by RECIST 1.1.
. Patients must have a ECOG performance status of 0 or 1.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

Frequency of Objective Tumor Response as Assessed by RECIST 1.1- Overall Response Rate (ORR)
Timeframe: 4 years

Toxicity Grade of Adverse Events as Assessed by CTCAE v4
. Women of childbearing potential must have a negative urine and serum pregnancy test within 72 hours prior to receiving first dose and must be willing to use contraceptive through 120 days of last dose of Pembrolizumab.
. Patients must have recovered from effects of recent surgery, radiotherapy, or chemotherapy. Patients with ≥ Grade 2 neuropathy are eligible.
. Patients may have received prior radiation therapy for treatment of endometrial cancer. Prior radiation therapy may have included pelvic radiation therapy, extended field pelvic/para-aortic radiation therapy, intravaginal brachytherapy and/or palliative radiation therapy. All radiation therapy must be completed at least 4 weeks prior to the first date of study therapy.
Exclusion criteria
. Patients who have had prior therapy with nivolumab, pembrolizumab 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 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 who are pregnant or nursing. The effects of pembrolizumab on the developing human fetus are unknown. For this reason, women of child-bearing potential (WOCBP) must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. WOCBP should use an adequate method to avoid pregnancy for 23 weeks after the last dose of investigational drug. WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IV/L or equivalent units of HCG) within 24 hours prior to the start of pembrolizumab. Women must not be breastfeeding.
. Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile or have undergone definitive radiation) do not require contraception.
. Patients with known brain metastases or leptomeningeal metastases are excluded unless the following conditions are met: Metastases have been treated and there is no evidence of progression by CT scan or magnetic resonance imaging (MRI) prior to the first dose of pembrolizumab administration). There must also be no requirement for immunosuppressive doses of systemic corticosteroids (\>10 mg/day prednisone equivalents) for at least 1 week prior to study drug administration.
. Patients should be excluded if they have known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS). Patients should be excluded if they have a positive test for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV antibody) indicating acute or chronic infection (e.g., HCV RNA \[qualitative\] is detected).
. Patients with active autoimmune 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 SLE, connective tissue diseases, scleroderma, inflammatory bowel disease (IRB), 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. Patient 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.
