Irinotecan DRUG

Irinotecan is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. This medication is classified as a "plant alkaloid" and "topoisomerase I inhibitor."

Also known as: Eloxatin

Single Arm iTTO treatment

TAS 102 (Trifluridine/Tipiracil) DRUG

Trifluridine/Tipiracil is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. This medication is classified as an antimetabolite/pyrimidine analog; antimetabolite/thymidine phosphorylase inhibitor

Also known as: Lonsurf

Single Arm iTTO treatment

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients must be 18 years of age or older.
• Histologically documented locally advanced or metastatic gastric or GEJ adenocarcinoma not previously treated with palliative systemic therapy.
• Patients must be capable of providing consent to enrolment and treatment.
• Patients with a performance status of ECOG 0-1 will be eligible for enrolment (see appendix 1).
• Measurable disease must be present according to RECIST criteria V1.1 (see appendix ).
• Women of child bearing potential (WOCBP) must have a negative serum (or urine) pregnancy test at the time of screening. WOCBP is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy or bilateral salpingectomy) and is not postmenopausal. Menopause is defined as 12 months of amenorrhea in a woman over age 45 years in the absence of other biological or physiological causes.
• Patients (men and women) of childbearing / reproductive potential should use highly effective birth control methods, as defined by the investigator, during the study treatment period and for a period of 6 months after the last dose of study drug. A highly effective method of birth control is defined as those that result in low failure rate (i.e. less than 1% per year) when used consistently and correctly. Note: abstinence is acceptable if this is established and preferred contraception for the patient and is accepted as a local standard.
• Female patients who are breast-feeding should discontinue nursing prior to the first dose of study treatment and until 30 days after the last dose of study drug.
• Male patients should agree to not donate sperm during the study and for a period of at least 6 months after last dose of study drug.
• Absence of any condition hampering compliance with the study protocol and follow- up schedule; those conditions should be discussed with the patient before registration in the trial.
• Patients may have received prior surgery if this surgery was ≥ 4 weeks before study entry and patients must have recovered from the toxic effects of this treatment.
• Patients who have treated brain metastasis (via local radiation standards or surgical resection or local ablative techniques) and who are either off steroids or on a stable dose of steroids for at least one month (30 days), AND who are off anticonvulsants, AND have radiological documented stability of lesions for at least 3 months may be eligible. Each case should be discussed with the study Chair.
• Patients who have received prior chemotherapy or radiation delivered as part of initial curative therapy (i.e. neoadjuvant or adjuvant chemotherapy administered alone and/or concurrently delivered with radiation and/or surgery) are permitted as long as that treatment was completed at least 6 months prior to study start date.
• Patients may have received prior palliative radiotherapy (unless radiation was curative therapy to pelvis or to ≥ 25% of bone marrow stores) if this radiation was ≥ 4 weeks before study entry and patients must have recovered from the toxic effects of this treatment.
• Patients with unknown Her2/neu status, or negative Her2/neu status based on IHC and/or FISH/CISH (Testing does not need to be done unless it is standard of care at participating centres).

You may not qualify if:

• Patients who have received prior palliative chemotherapy for their advanced gastric or GEJ tumor.
• Prior curative or palliative radiation treatment to the pelvis or radiation therapy to ≥ 25% of bone marrow stores.
• History of bowel obstruction due to peritoneal metastases or clinically documented ascites requiring paracenteses.
• Previous or concurrent malignancies, excluding curatively treated in situ carcinoma of the cervix or uterus or non-melanoma skin cancer or in-situ carcinoma of the prostate (Gleason score ≤ 7, with all treatment being completed 6 months prior to enrollment, unless at least 5 years have elapsed since last treatment and the patient is considered cured).
• Active bacterial, viral, or fungal infection(s) requiring systemic therapy, defined as ongoing signs/symptoms related to the infection without improvement despite appropriate antibiotics, antiviral therapy, and/or other treatment.
• Known infection with hepatitis B or C, or history of human immunodeficiency virus (HIV) infection, or subject receiving immunosuppressive or myelosuppressive medications that would, in the opinion of the investigator, increase the risk of serious neutropenic complications.
• Any serious medical condition within 6 months prior to study entry such as myocardial infarction, uncontrolled congestive heart failure, unstable angina, active cardiomyopathy, unstable ventricular arrhythmia, cerebrovascular diseases, uncontrolled hypertension, uncontrolled diabetes, uncontrolled psychiatric disorder, serious infection, active peptic ulcer disease, or other medical condition that may be aggravated by treatment.
• Pre-existing neuropathy ≥ grade 2 from any cause.
• Patients with unstable metastasis to the central nervous system (CNS). A CT scan or MRI is NOT required to rule out brain metastases unless there is clinical suspicion of CNS involvement.
• Pregnant or lactating women; women of child bearing potential must have a negative serum pregnancy test within 7 days of trial registration. Women or men of child bearing potential must use effective contraception (defined by the treating physician) which must be documented in study CRFs.
• History of allergic reaction to planned study medications.
• Patient has a ≥ 20% decrease in serum albumin level between baseline visit, if available, and within 72 hours prior to first study treatment dose.
• Patient is on coumadin.
• History of interstitial lung disease.
• History of connective tissue disorders (e.g. lupus, scleroderma, polyarteritis nodosa).
