简要总结
This phase II trial studies the side effects of azacitidine and pembrolizumab and to see how well they work in treating patients with myelodysplastic syndrome. Azacitidine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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. Giving azacitidine and pembrolizumab may work better at treating myelodysplastic syndrome.
详细描述
PRIMARY OBJECTIVES:
I. To assess the safety of the combination of azacitidine and MK3475 (pembrolizumab) in patients with higher risk myelodysplastic syndrome (MDS).
II. To explore the clinical activity (response, survival effect) of the combination of azacitidine with MK-3475 in patients with higher risk MDS.
EXPLORATORY OBJECTIVES:
I. To study the biological effects of the combination of azacitidine and pembrolizumab in patients with MDS treated on this study.

入选标准
- •Voluntary signed informed consent before performance of any study related procedure not part of normal medical care indicating that the patient is aware of the investigation and nature of this study in keeping with institutional policies and with the understanding that the consent may be withdrawn with the subject at any time without prejudice to future medical care
- •Intermediate 1 (INT-1) or higher risk MDS defined by International Prognostic Scoring System (IPSS) criteria
- •Patients can or cannot have receive prior therapy with hypomethylating agent but will be allocated to specific patient cohorts based on their prior exposure. Patients that had received prior hypomethylating agent therapy should have at least received 6 cycles of therapy and not achieved any response or had progressed after any given number of cycles
- •Eastern Cooperative Oncology Group (ECOG) performance of 0 to 2
- •Male patients, even if surgically sterilized, should agree to practice effective barrier contraception for the entire study treatment period and through 120 days after the last dose of the study treatment or agree to completely abstain from heterosexual intercourse. Female patients who are postmenopausal for at least one year before the screening visit or are surgical sterile or if they are of child bearing potential must have a negative pregnancy test within 72 hours of treatment of the start date and agree to practice two effective methods of contraception forms at the same time from the time of signing the informed consent through 120 days of the last dose of the study treatment or agree to completely abstain from heterosexual intercourse
- •Willingness and ability to comply with scheduled visits treatment plans, laboratory tests and other study procedures
- •Serum creatinine or measured or calculated creatine clearance (glomerular filtration rate [GFR] can also be used in place of creatinine or creatinine clearance [CrcL]) =< 2.0 x upper limit of normal (ULN) or >= 60 mL/min for subject with creatinine levels > 1.5 x institutional ULN (performed within 10 days of treatment initiation). Creatinine clearance should be calculated per institutional standard
- •Serum total bilirubin =< 2.0 x ULN (unless considered due to Gilbert's disease or leukemia disease) or direct bilirubin =< ULN for subjects with total bilirubin levels > 1.5 ULN (performed within 10 days of treatment initiation)
- •Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x ULN (unless considered due to Gilbert's disease or leukemia disease) or =< 5 x ULN for subjects with liver metastases (performed within 10 days of treatment initiation)
- •Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
- •Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year
- •Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy
- •Patients must receive a minimum dose of azacitidine of 75mg/(m)(2) dose
排除标准

- •Any severe or concurrent disease or condition including uncontrolled systemic infection, congestive heart failure, angina pectoris or cardiac arrhythmia and autoimmune processes that in the opinion of the investigator would make the patient inappropriate for study participation
- •Patients with known hypersensitivity to 5-azacitidine or MK3475 or any of their excipients
- •Prior history of stem cell transplantation
- •For patients in the relapse or refractory cohort, any other therapy not being a hypomethylating agent after hypomethylating agents (HMA) failure or more than 4 months since completion of last cycle of hypomethylating agent. Please note that hypomethylating agent may include second generation compounds such as SGI-110, oral decitabine or oral azacitidine and will also include combinations with investigational agents
- •Treatment with other investigational agents including chemotherapy, immunotherapy, or radiation therapy within a month prior to the start of this clinical trial
- •Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment
- •Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment
- •Has a known history of active TB (Bacillus tuberculosis)
- •Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier
- •Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to a previously administered agent. Note: Subjects with =< grade 2 neuropathy are an exception to this criterion and may qualify for the study. Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy

结局指标
主要结局
Overall Response Rate (ORR) Defined as Complete Response + Partial Response + Hematological Improvement
时间窗: Up to 2 years 4 months
Will estimate the ORR for the experimental treatments, along with the 95% credible intervals. The association between ORR and patient's clinical characteristics will be examined by Wilcoxon's rank sum test or Fisher's exact test, as appropriate.
Event Free Survival
时间窗: Up to 4 years
Will be estimated using the method of Kaplan and Meier. Comparisons of time-to-event endpoints by important subgroups will be made using the log-rank tests.
Overall Survival
时间窗: Up to 4 years
Will be estimated using the method of Kaplan and Meier. Comparisons of time-to-event endpoints by important subgroups will be made using the log-rank tests. Overall Survival will be presented by median survival, which is the time point at which the cumulative survival drops below 50%. If there is no median survival (not reached), it means the cumulative survival was more than 50%.
