Chemotherapy

Purpose
This will be an international, multicenter, uncontrolled, 2-stage, phase II study in adult patients with advanced gastric
cancer, reasonable performance status, good organ function, lack of serious concomitant medical conditions. Patients must
have progressed or recurred after a fluoropyrimidine-containing regimen at anytime for primary metastatic disease or within
6 months of last dose of adjuvant therapy. Twenty-one evaluable patients will be enrolled in Stage 1. If at least 2 objective
tumor responses are observed in the first 21 evaluable patients, the study will be expanded to enroll a total of 41 evaluable
patients. Edotecarin will be administered at a starting dose of 13 mg/m2 as an IV infusion over 60 minutes in repeated 3-week
cycles treatment.
The primary objective will be to assess the antitumor activity of edotecarin by repeating radiographic assessments at 6-week
intervals for all patients. Secondary efficacy objectives will be to determine the time of onset and duration of tumor control,
and overall survival. In addition, the safety and tolerability profile of edotecarin will be assessed, and plasma pharmacokinetic
(PK) profile of edotecarin will be evaluated. Blood samples for PK evaluation will be collected during Cycles 1 and 2 and
limited to the patients included in the first stage of the study.

Eligibility
Ages Eligible for Study:
18 Years and above,
Genders Eligible for Study:
Both
Inclusion Criteria:
- Histologically or cytologically confirmed diagnosis of gastric adenocarcinoma or gastroesophagael junction adenocarcinoma
(i.e., an adenocarcinoma with >50% extension in the stomach)
- Presence of locally advanced or metastatic disease non-amenable to surgery +/- chemo-radiation with curative intent
- Progression or recurrence after a fluoropyrimidine-containing regimen at any time for primary metastatic disease or within
6 months of last dose of adjuvant therapy
- Presence of at least 1 measurable (target) lesion. Target lesions are defined as those lesions that can be measured in at
least 1 dimension as >=20mm with conventional techniques or >=10mm with spiral computerized tomography (CT) scan. Previously
irradiated lesions will not be considered as target lesions.
- All previous therapies must have been discontinued at least 4 weeks before study entry, and all acute toxic effects (excluding
alopecia or neurotoxicity) of any prior therapy must have resolved to NCI CTC (Version 2.0) Grade <= (please see inclusion
criteria #8 below for exceptions)
- Age >= 18 years
- ECOG performance status of 0, 1 or 2
- Baseline tests within the following limits: Absolute neutrophil count (ANC) >= 1500/mm3 (1.5 x 10(9)/L) Platelets >= 100,000/mm3
(100 x 10(9)/L) Hemoglobin >= 9.0 g/dL Serum creatinine <= 1.5 mg/dl (or <= 133 mmol/L) Total serum bilirubin <= 1.5 x upper
limits of normal (ULN) regardless of liver involvement secondary to tumor SGOT <= 2.5 x ULN; <=5 x ULN if there is liver involvement
secondary to tumor Albumin >=3.0 g/dL Pregnancy test for females of childbearing potential is negative within 7 days of starting
treatment
- Evidence of personally signed and dated informed consent document indicating that the patient (or legally acceptable representative)
has been informed of all pertinent aspects of the trial
- Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and other study procedures
Exclusion Criteria:
- Prior treatment with another topoisomerase I inhibitor
- More than 1 prior chemotherapy regimen for advanced disease
- Prior radiation therapy to >25% of the bone marrow
- Any investigational agent received in the 4 weeks before enrollment to this study and/or current enrollment in another therapeutic
clinical trial
- Previous high-dose chemotherapy requiring hematopoietic stem cell rescue
- Known brain metastases, or spinal cord compresssion, or carcinomatous meningitis (baseline CT or magnetic resonance imaging
(MRI) scan of the brain required only in case of clinical suspicion of central nervous system metastases)
- Previous (within the last 5 years) or current malignancies at other sites, except for adequately treated basal cell or squamous
cell skin cancer or in situ carcinoma of the cervix uteri
- Active inflammatory bowel disease, partial or complete bowel obstruction or chronic diarrhea
- Any of the following in the past 6 months: myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass
graft, symptomatic congestive heart failure, cerebrovascular accident or transient ischemic attack, pulmonary embolism, deep
vein thrombosis or other significant thromboembolic event
- Ongoing cardiac dysrhythmias of NCI CTC grade >=2, atrial fibrillation of any grade
- Active infection, including known human immunodeficiency virus (HIV) postivity
- Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated
with study participation or study drug administration or may interfere with the interpretation of study results and, in the
judgement of the investigator, would make the subject inappropriate for entry into this study
- Pregnancy or breast-feeding. Female patients must be surgically sterile or be postmenopausal, or must agree to use effective
contraception during the period of therapy. Fertile patients who are refusing to use reliable contraceptive methods
