简要总结
This research study is studying a targeted therapy as a possible treatment for advanced esophageal cancer.
The study intervention involved in this study is:
-Pembrolizumab
详细描述
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied.
The FDA (the U.S. Food and Drug Administration) has not approved Pembrolizumab for the participant specific disease but it has been approved for other uses.
Pembrolizumab, also known as KEYTRUDA or MK-3475, is approved in the USA and several other countries to treat other types of diseases.
The goal of this research study is to
-Evaluate the safety and efficacy of pembrolizumab in participants with advanced esophageal cancer that have not responded to standard treatment.

入选标准
- •Histologically confirmed, measurable, unresectable adenocarcinoma or squamous cell carcinoma of the esophagus. For the purposes of this study, undifferentiated carcinomas or adenosquamous carcinomas will be categorized as adenocarcinomas.
- •The primary tumor must originate in the esophagus. Tumors that involve the GE junction must meet Sievert Type 1 criteria: "Adenocarcinoma of the distal oesophagus which usually arises from an area with specialized intestinal metaplasia of the oesophagus (i.e. Barrett's oesophagus) and which may infiltrate the oesophagogastric junction from above." For the purposes of this protocol, this will be interpreted as: greater than 50% of the tumor must be above the GE junction or, alternatively, the tumor must involve the GE junction and arise in the setting of biopsy-documented Barrett's esophagus (specialized intestinal metaplasia).
- •Patients must have received at least one prior therapy for unresectable disease. Patients with recurrence within 6 months of completion of neoadjuvant or adjuvant therapy may be considered as having received one prior therapy for unresectable disease.
- •Be willing and able to provide written informed consent/assent for the trial.
- •Be ≥ 18 years of age on day of signing informed consent.
- •Have measurable disease based on irRECIST.
- •Be willing to provide tissue from a newly obtained biopsy of a tumor lesion, most commonly an EGD biopsy from the esophagus. Newly-obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on Day
- •Subjects for whom newly-obtained samples cannot be provided (e.g. inaccessible or subject safety concern) may submit an archived specimen only upon agreement from the Sponsor. Please note, patients may not initiate therapy until the biopsy specimen is received at the Dana-Farber Cancer Institute.
- •The first 15 patients with adenocarcinoma will be offered an optional tumor biopsy (typically EGD biopsy) at 8 weeks. Starting with adenocarcinoma patient #16, patients must have an accessible tumor and must agree to tumor biopsy at 8 weeks; this will continue to be mandatory until a total of 20 patients have undergone biopsy at 8 weeks.
- •Have a performance status of 0 or 1 on the ECOG Performance Scale (Appendix A).
- •Female subject of childbearing potential must 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 must 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 (Reference Section 6.3.2). Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.
- •Male subjects must 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.
- •Demonstrate adequate organ function as defined below, all screening labs should be performed within 10 days of treatment initiation.
- •Hematological
- •Absolute neutrophil count (ANC) ≥1,500 /mcL
- •Platelets ≥80,000 / mcL
- •Hemoglobin ≥8.5 g/dL or ≥5.6 mmol/L
- •Serum creatinine ≤1.5 X upper limit of normal (ULN) OR Measured creatinine clearance ≥60 mL/min for subject with creatinine levels > 1.5 X institutional ULN (GFR can also be used in place of creatinine or CrCL) Creatinine clearance should be calculated per institutional standard.
- •Serum total bilirubin ≤ 1.5 X ULN OR Direct bilirubin ≤ ULN for subjects with total bilirubin levels > 1.5 ULN
- •AST (SGOT) ≤ 2.5 X ULN OR ≤ 5 X ULN for subjects with liver metastases
- •ALT (SGPT) ≤ 2.5 X ULN OR ≤ 5 X ULN for subjects with liver metastases
- •Albumin > 2.8 mg/dL
- •Coagulation
- •International Normalized Ratio (INR) OR Prothrombin Time (PT) ≤1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
- •Activated Partial Thromboplastin Time (aPTT) ≤1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
排除标准
- •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. Subjects requiring systemic steroids are excluded from the trial. The use of physiologic doses of corticosteroids may be approved after discussion with the sponsor.
- •Has a known history of active TB (Bacillus Tuberculosis)
- •Hypersensitivity to pembrolizumab or any of its excipients.
- •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 and alopecia are an exception to this criterion and may qualify for the study.
- •Note: If subject received major surgery, they must wait ≥ 3 weeks prior to starting study treatment. They must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
- •Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.

Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
- •Has an active infection requiring systemic therapy.
- •Patients that require supplemental oxygen are excluded.
- •Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator.

结局指标
主要结局
Overall Response Rate (ORR)
时间窗: Disease was evaluated each cycle on treatment; Treatment continued until disease progression or unacceptable toxicity. Treatment duration was a median of 2.1 months with a maximum of 14.9 months.
The objective response rate (ORR) was defined as the proportion of participants achieving complete response (CR) or partial response (PR) based on RECIST 1.1 criteria on treatment. Per RECIST 1.1 for target lesions: CR is complete disappearance of all target lesions and PR is at least a 30% decrease in the sum of longest diameter (LD) of target lesions, taking as reference baseline sum LD. PR or better overall response assumes at a minimum incomplete response/stable disease (SD) for the evaluation of non-target lesions and absence of new lesions.
次要结局
- Median Progression-free Survival (PFS)(Disease was evaluated each cycle on treatment and in long-term follow-up every 12 weeks for up to 5 years. Maximum follow-up in this study cohort was 28.9 months)
- Number of Patients Experiencing Grade 3-4 Treatment-Related Toxicity(Assessed each cycle throughout treatment from time of first dose and up to day 30 post-treatment. Median treatment duration for this study cohort was 2.1 months with maximum of 14.9 months.)
- Median Overall Survival (OS)(Disease was evaluated each cycle on treatment and in long-term follow-up every 12 weeks for up to 5 years. Maximum follow-up in this study cohort was 38.7 months.)
