Overview

Trial of Docetaxel, Oxaliplatin and Capecitabine (TEX) in Advanced or Metastatic Gastric Cancer

Status:
Completed
Trial end date:
2013-01-01
Target enrollment:
0
Participant gender:
All
Summary
Combination regimens of 3 active drugs have shown promising activity in treatment of metastatic gastric cancer. Docetaxel combined with cisplatin and 5-fluorouracil (FU) yielded superior overall survival and response rates when compared to standard cisplatin and 5-FU. However, a toxicity profile showed the need for development of less toxic modifications. In a prior phase I trial, the maximum tolerated dose was defined. In this phase II trial, a first evaluation of activity will be performed.
Phase:

1. T4 infiltrating of several organs

2. T4 infiltrating one organ, but irresectable

3. T4 infiltrating one organ, respectable, but inoperable patient

- The nodal status is neglected

- Measurable disease according to RECIST

- ECOG Performance Status ≤ 2

- Male or female patients aged ≥ 18 years

- Life expectancy ≥ 3 months

- Adequate bone marrow, hepatic and renal function:

1. Haemoglobin > 9.0 g/dL (transfusions allowed to achieve or maintain levels)

7. Creatinine clearance > 50 mL/min (calculated according to Cockroft and Gault)

- Prior surgery must be more than 28 days ago

- Positive nodes as diagnosed on endorectal ultrasound and/or MRI (tumour is staged by
preferably a high resolution MRI; if MRI is not available, locoregional staging must
be performed by computed tomography plus endorectal ultrasound)

- Tumor staging must be done within 28 days from the start of the treatment

- Negative pregnancy test in women with childbearing of potential (within 7 days prior
to the start of the chemotherapy)

- Postmenopausal women must have been amenorrheic for at least 12 months to be
considered of non-childbearing potential

Exclusion Criteria:

- Prior cytotoxic chemotherapy or radiotherapy (a neoadjuvant or adjuvant chemotherapy
must be completed and without progression for at least 6 months)

adequately treated in situ carcinoma of the cervix or basal cell carcinoma of the skin

- Peripheral neuropathy ≥ grade 2 (according to NCI CTCAE v 3.0)

- Patient must not have been treated with any investigational drug, agent nor procedure,
(i.e., did not participate in another trial within 30 days) before entry in this trial

- Known allergy or any other adverse reaction to any of the study drugs or to any
related compound

- Requirement for concurrent use of the antiviral agent sorivudine (antiviral) or
chemically related analogues, such as brivudine

- Clinically significant concomitant diseases, such as:

1. Active infection necessitating systemic antibiotics

2. Interstitial lung diseases

3. Chronic diarrhea, inflammatory bowel disease

4. Neurological or psychiatric disease, dementia, epilepsy or untreated brain
metastases

- Cardiac disease (e.g., congestive heart failure, symptomatic coronary artery disease
and cardiac arrhythmia not well controlled with medication) or myocardial infarction
