Stomach Neoplasms Clinical Trial
Official title:
Prospective, Open, Multicentre Phase I/II Study to Evaluate the Safety and Efficacy of a Neoadjuvant Radiochemotherapy With Docetaxel and Oxalipaltin in Patients With Adenocarcinoma of the Gastric-oesophageal Junction
The purpose of this study is to determine the dose limiting toxicity and the maximum tolerable dose of the radiochemotherapy with Docetaxel and Oxaliplatin in patients with adenocarcinoma of the gastric-oesophageal junction.
Radiotherapy starts on day 1 of chemotherapy after the application of Docetaxel and
Oxaliplatin and will be administered in single doses of 1.8 Gy once daily and five times a
week for 5 weeks.
In the sixth treatment week a boost of 3 further radiations with 1.8 Gy will be applied.
Simultaneous chemotherapy:
Initially, in part A of the study the maximum tolerable dose (MTD) for the simultaneous
chemotherapy will be identified with a 3-step dose escalation scheme:
Level 1: Docetaxel: 20 mg/m2 Oxaliplatin 40 mg/m2 i.v., Level 2: Docetaxel: 20 mg/m2
Oxaliplatin 50 mg/m2 i.v., Level 3: Docetaxel: 25 mg/m2 Oxaliplatin 50 mg/m2 i.v.,
The treatment starts with 3 patients in level 1. If no dose limiting toxicities appear, it
will be switched to dose level 2. The same applies for the switch from level 2 to level 3.
If a DLT appears on one level, a further 3 patients will be treated within this dose level.
If in one level at least 2 of 6 patients show DLT, the subjacent level will be defined as
the maximum tolerable dose (MTD).
