What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CapecitabineDrug
Also called Xeloda, Ro09-1978
Capecitabine is available as 50 mg and 500 mg tablets. It will be administered as a 1000mg/m^2 bid orally on Days 1-14, and at a dose of 825mg/m^2 bid on Days 22-35 and 43-56.
OxaliplatinDrug
Also called Eloxatin
Oxaliplatin is available in vials containing 50 mg or 100 mg. It will be administered as a oxaliplatin 130mg/m^2/d intravenously on Day 1 and 50mg/m^2/d on Days 22, 29, 43 and 50 prior to radiotherapy up to Week 9 followed by surgery period.
| Study group | Role | What they receive |
|---|---|---|
| Capecitabine+Oxaliplatin | Experimental | Eligible participants received capecitabine 1000 milligrams per square meter (mg/m^2) on Days 1-14, and 825 mg/m^2 on Days 22-35 and 43-56 twice a day (bid) orally, along with oxaliplatin as a 2-hour intravenous (iv) infusion of 130 mg/m^2/once a day (d) on Day 1 and 50 mg/m^2/d on Days 22, 29, 43 and 50 prior to radiotherapy. Participants received radiation therapy having a fraction dose of 1.8 gray (Gy)/day, 5 days a week, for five consecutive weeks starting on Day 22 of the treatment period. Participants, who completed the treatment period, underwent surgery at Week 14. Receives: Drug: Capecitabine; Drug: Oxaliplatin |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Pathological Complete Tumor Response
Pathological complete tumor response was defined as grade 3 or 4 in the histological grading of regression according to Dworak classification. Grade 0 is no regression; Grade 1 is dominant tumor mass with obvious fibrosis and/or vasculopathy; Grade 2 is dominantly fibrotic changes with few tumor cells or groups; Grade 3 is defined as very few (difficult to find microscopically) tumor cells in fibrotic tissue with or without mucous substance; Grade 4 is defined as no tumor cells, only fibrotic mass (total regression or response).
Measured: Up to Week 16
Secondary outcomes (6)
Percentage of Participants With Sphincter-preservation
Percentage of participants with sphincter-preservation is reported.
Measured: Up to Week 16
Number of Participants With Marked Laboratory Abnormalities
Number of participants with marked laboratory abnormalities is reported.
Measured: Up to Week 16
Percentage of Participants With Resection (R0) in Participants With T4 Rectal Cancer
R0 resection was defined as complete resection of the tumor with adequate tumor-free margins and regional lymph node extirpation as confirmed by pathology after pre-operative chemotherapy plus capecitabine + oxaliplatin therapy.
Measured: Up to Week 16
Percentage of Participants With Downstaging of Primary Tumor and/or Lymph Nodes
Downstaging of primary tumor (T) and/or lymph nodes (N) was defined as decrease by 1 point in T-value and/or N-value (comparing at screening and after treatment). It was assessed by colonoscopy, pathology, endosonography of rectum, chest X-ray, abdominopelvic Computed Tomography and Magnetic Resonance Imaging. Staging for tumor are: TX (primary tumor cannot be assessed), T0 (no evidence of primary tumor), Tis (carcinoma in situ), T1 (tumor invades submucosa), T2 (tumor invades muscularis propria), T3 (tumor invades through muscularis propria into subserosa/into non-peritonealized pericolic/perirectal tissues, T4 (tumor directly invades other organs or structures). Staging for lymph nodes are: NX (regional lymph nodes cannot be assessed), N0 (no regional lymph node metastasis), N1 (metastasis in 1 to 3 regional lymph nodes), N2 (metastasis in 4 or more regional lymph nodes).
Measured: From screening to Week 16
Percentage of Participants With Pathological Incomplete Tumor Response
Pathological incomplete tumor response was defined as grade 1 or 2 in the histological grading of regression according to Dworak grading of regression. Pathological incomplete tumor response rate, Grade 1: dominant tumor mass with obvious fibrosis and/or vasculopathy; Grade 2: dominantly fibrotic changes with few tumor cells or groups (easy to find) were assessed.
Measured: Up to Week 16
Number of Participants With Any Adverse Events and Serious Adverse Events
An adverse event (AE) is defined as any untoward medical occurrence in participants or clinical investigation participants administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment. A serious adverse event (SAE) is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect.
Measured: Up to Week 16

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Capecitabine and Oxaliplatin in people with Rectal Cancer, run by Hoffmann-La Roche at 6 sites in Switzerland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 9 Nov 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants With Pathological Complete Tumor Response (time frame: Up to Week 16). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jan 2017.
