General information about the trial
|
|||
Main objective of the trial |
To evaluate feasibility and tolerance of an induction chemotherapy (Capecitabine/Oxaliplatin) in combination with Bevacizumab (Avastin®) followed by combined radiochemotherapy with Capecitabine (Xeloda®) in patients with locally advanced rectal carcinoma
|
||
Protection of trial subjects |
The study specific patient information and informed consent form included language to encourage study participants to reach out to the Study Doctor / Study Team in case they have any questions, concerns or doubts. Section 14 specifically referenced a 24/7 contact person to reach out to and the ICF contained a reference to the local ombudsman / patient advocacy. A dedicated IDMC was established to ensure patient safety throughout the trial.
|
||
Background therapy |
Oxaliplatin was administered as part of the induction chemotherapy in a dose of 130 mg/m2 bid, for 3 cycles, on day 1, 22 and 43 (+/- 2 days). Oxaliplatin was no study medication – it was used in this study as non-investigational product (NIMP). | ||

Bevacizumab (Avastin®), 25mg/ml, a concentrate for solution for infusion. 100 mg or 400 mg vial diluted with 0.9% NaCl to 100 ml. First infusion during 90 minutes, in case of good tolerability the further infusions can be administered during 60 minutes and then 30 minutes. 7.5 mg Bevacizumab/kg body weight every 21 days. Bevacizumab was administered at day 1 (+/- 2 days), 22 (+/- 2 days) and 43 (+/- 2 days). Patients take a dose of 7.5 mg/kg body weight (diluted with NaCl 0.9% to 100ml) of Bevacizumab on day 1 of each cycle.

Dosage and administration details |
Capecitabine (Xeloda®) is an approved treatment and therefore was no study treatment (NIMP). Dosage was calculated according to the respective body surface: 1000 mg/m2/bid p.o.. Patients were administered Capecitabine in the form of tablets according to the following scheme:
• day 1 – 14, followed by 1 week off treatment
• day 22 – 35 followed by 1 week off treatment
• day 43 – 56 followed by 1 week off treatment
Capecitabine was taken twice a day with 12 hours between each intake, 30 minutes after a meal.

Subject analysis set description |
The ITT analysis set was defined as all patients who started preoperative treatment. Post resection for inconclusive histology showed on one patient no tumour invasion. This patient did not take any doses of Bevacizumab chemotherapy or any other study therapy and was as such, according to protocol, not included in the ITT analysis set.
