This research study is studying a targeted therapy as a possible treatment for advanced anal cancer.
The following intervention will be involved in this study:
|Condition or disease||Intervention/treatment||Phase|
|Anal Cancer||Drug: Pembrolizumab||Phase 2|
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 Advanced Anal Cancer, 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 a type of skin cancer called Malignant Melanoma.
In this research study the investigators are studying an investigational drug called Pembrolizumab, which is a monoclonal antibody. Monoclonal antibodies are manmade and mimic proteins in the immune system by attaching to specific proteins in the body. T cells are cells in the immune system that are controlled by PD-1. PD-1 is a protein on the T cells that prevent the body from overproducing T cells. Pembrolizumab targets PD-1, attaches to it and blocks its action. By preventing PD-1 from working, T cell production rises and the body's immune system may increase its action against Cancer cells. Clinical and laboratory studies using pembrolizumab suggest that pembrolizumab may be useful in shrinking certain tumors.
|Study Type :||Interventional (Clinical Trial)|

|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||A Multicenter Phase 2 Clinical Trial of Pembrolizumab in Metastatic Anal Cancer|
|Actual Study Start Date :||October 11, 2016|
|Actual Primary Completion Date :||December 2021|
|Estimated Study Completion Date :||March 2023|
Pembrolizumab 200 mg will be administered as a 30 minute IV infusion every 3 weeks.
- Overall Response Rate [ Time Frame: 36 months ]Overall response rate of pembrolizumab in metastatic anal cancer patients will be evaluated by RECIST 1.1.
- PD-L1 Positive Response Rate [ Time Frame: 36 months ]Response rate in PD-L1 positive metastatic anal cancer patients will be evaluated by RECIST 1.1.
- Overall Survival [ Time Frame: 36 months ]Evaluate the durability of pembrolizumab responses in PD-L1 positive metastatic anal cancer patients by measuring median overall survival.
- Progression Free Survival [ Time Frame: 36 months ]Evaluate the durability of pembrolizumab responses in PD-L1 positive metastatic anal cancer patients by measuring median progression free survival.
- Incidence of Adverse Events to Evaluate the Safety and Tolerability of Pembrolizumab [ Time Frame: Every 3 Weeks, from the time the informed consent is signed through 90 days following cessation of treatment ]Assess how well pembrolizumab is tolerated in patients with metastatic anal cancer by evaluating adverse events by CTCAE v4.0.

|Ages Eligible for Study:||18 Years and older (Adult, Older Adult)|
|Sexes Eligible for Study:||All|
|Accepts Healthy Volunteers:||No|
- Participants must have metastatic anal cancer that has been histologically confirmed.
- There is no limit to the number of prior therapies.
- 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 RECIST 1.1.
- Be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion. Newly-obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on Day 1. 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.
- Have a performance status of 0 or 1 on the ECOG Performance Scale.
- Demonstrate adequate organ function, all screening labs must be performed within 10 days of treatment initiation.
Adequate Organ Function Laboratory Values
System Laboratory Value
- Absolute neutrophil count (ANC) ≥1,500 /mcL
- Platelets ≥80,000 / mcL
- Hemoglobin ≥8.5 g/dL or ≥5.6 mmol/L
--Serum creatinine OR Measured or calculated creatinine clearance (GFR can also be used in place of creatinine or CrCl) ≤1.5 X upper limit of normal (ULN) OR ≥60 mL/min for subject with creatinine levels > 1.5 X institutional ULN
- Serum total bilirubin ≤ 1.5 X ULN OR Direct bilirubin ≤ ULN for subjects with total bilirubin levels > 1.5 ULN
- AST (SGOT) and ALT (SGPT) ≤ 2.5 X ULN OR ≤ 5 X ULN for subjects with liver metastases
- Albumin >2.8 mg/dL
- 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
- Creatinine clearance should be calculated per institutional standard.
- 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 7.4). Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.
