Colon Cancer Clinical Trial

Pembrolizumab in Early Stage Colon Cancer

Summary

This study will gather information on the safety and effectiveness of pembrolizumab, an immunotherapy drug. The purpose of this study is to target early stage colon cancer before it has developed resistance to immunotherapy.

Eligibility Criteria

Inclusion Criteria:

Patients must have histologically confirmed colon adenocarcinoma.
No prior chemotherapy, targeted therapy, or immunotherapy for colon cancer.
Deemed to have surgically resectable disease.
Archival tissue block containing colon adenocarcinoma must be confirmed available prior to enrollment. MSI testing should be obtained prior to starting therapy.
Be willing and able to provide written informed consent/assent for the trial.
Be 18 years of age or older on day of signing informed consent.
Have a measurable primary lesion by lower endoscopy or CT-imaging with a diameter of 1 or more centimeters.
Have a performance status of 0 or 1 on the ECOG Performance Scale.
Have no histologically confirmed disseminated disease by CT or PET-CT staging.
Male participant must agree to use a contraception as detailed in Appendix 3 of this protocol during the treatment period and for at least 120 days after the last dose of study treatment and refrain from donating sperm during this period.

A female participant is eligible to participate if she is not pregnant (see Appendix 3), not breastfeeding, and at least one of the following conditions applies:

Not a woman of childbearing potential (WOCBP) as defined in Appendix 3 OR
A WOCBP who agrees to follow the contraceptive guidance in Appendix 3 during the treatment period and for at least 90 days after the last dose of study treatment.

Demonstrate adequate organ function as defined below. All screening labs should be performed within 14 days of treatment initiation.

Adequate Organ Function Laboratory Values

Hematological
Absolute neutrophil count (ANC) - ≥1500/µL
Platelets - ≥100 000/µL

Hemoglobin - ≥7.0 g/dL or ≥5.6 mmol/La

Renal

Creatinine OR measured or calculated creatinine clearance (GFR can also be used in place of creatinine or CrCl) - ≤1.5 × ULN OR

30 mL/min for participant with creatinine levels >1.5 × institutional ULN

Hepatic
Total bilirubin - ≤1.5 ×ULN OR direct bilirubin ≤ULN for participants with total bilirubin levels >1.5 × ULN

AST (SGOT) and ALT (SGPT) - ≤2.5 × ULN (≤5 × ULN for participants with liver metastases)

Coagulation

International normalized ratio (INR) OR prothrombin time (PT)/ Activated partial thromboplastin time (aPTT) - ≤1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants

ALT (SGPT)=alanine aminotransferase (serum glutamic pyruvic transaminase); AST (SGOT)=aspartate aminotransferase (serum glutamic oxaloacetic transaminase); GFR=glomerular filtration rate; ULN=upper limit of normal.
Criteria must be met without erythropoietin dependency and without packed red blood cell (pRBC) transfusion within last 2 weeks.
Creatinine clearance (CrCl) should be calculated per institutional standard. Note: This table includes eligibility-defining laboratory value requirements for treatment; laboratory value requirements should be adapted according to local regulations and guidelines for the administration of specific chemotherapies.

Exclusion Criteria:

A WOCBP who has a positive urine pregnancy test during screening (see Appendix 3). If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
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)
Known hypersensitivity to pembrolizumab or any of its excipients.
If subject received major surgery, 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.
Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
Has a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis.
Has an active infection requiring systemic therapy.
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.
Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.
Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).
Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA [qualitative] is detected).
Has received a live vaccine within 30 days of planned start of study therapy.
Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of trial treatment.
Has complications from colon cancer including but not limited to organ fistulas, bleeding and obstruction.
