What is being measured
The primary outcome is the main question the study is designed to answer.
OS in Participants With Left-sided Tumors
OS was measured as the time from the date of randomization to the date of death due to any cause. The left-sided tumors were defined as primary tumors occupying a left-sided site include the descending colon, sigmoid colon, and rectum.
Measured: Up to approximately 60 months
Overall Survival (OS) in All Participants
OS was measured as the time from the date of randomization to the date of death due to any cause.
Measured: Up to approximately 60 months
Secondary outcomes (6)
Progression-Free Survival (PFS) in Participants With Left-sided Tumors
PFS was defined as the time from the date of randomization to the earlier of Progressive Disease (PD) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 or death due to any cause. The left-sided tumors were defined as primary tumors occupying a left-sided site include the descending colon, sigmoid colon, and rectum.
Measured: Up to approximately 60 months
Progression-Free Survival (PFS) in All Participants
PFS was defined as the time from the date of randomization to the earlier of Progressive Disease (PD) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 or death due to any cause.
Measured: Up to approximately 60 months
Response Rate (RR) in All Participants
RR was defined as number of participants who achieve Complete Response (CR) and Partial Response (PR) as the best overall response per RECIST version 1.1.The best overall response was CR, followed by PR, stable disease (SD), progressive disease (PD), and not evaluable (NE). CR: disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to <10 mm. PR: at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters as the best overall response after randomization., SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study).
Measured: Up to approximately 60 months
Duration of Response (DOR)
DOR means that the period from the day when either CR or PR is first confirmed until the day of documented PD or the day of death due to all causes, whichever occurs earlier.
Measured: Up to approximately 60 months
Number of Participants Treated With Curative Surgical Resection After Chemotherapy
Curative surgical resection was defined as complete resection.
Measured: Up to approximately 60 months
Number of Participants With Treatment-emergent Adverse Events (TEAE)
Adverse event (AE) was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have a causal relationship with this treatment. A TEAE was defined as an adverse event with an onset that occurred in the treatment period after receiving the protocol treatment.
Measured: Up to approximately 60 months

Primary outcome
OS in Participants With Left-sided Tumors
Time frame: Up to approximately 60 months
OS was measured as the time from the date of randomization to the date of death due to any cause. The left-sided tumors were defined as primary tumors occupying a left-sided site include the descending colon, sigmoid colon, and rectum.
Overall Survival (OS) in All Participants
Time frame: Up to approximately 60 months
OS was measured as the time from the date of randomization to the date of death due to any cause.
6 secondary outcomes
Progression-Free Survival (PFS) in Participants With Left-sided Tumors
Time frame: Up to approximately 60 months
Progression-Free Survival (PFS) in All Participants
Time frame: Up to approximately 60 months
Response Rate (RR) in All Participants
Time frame: Up to approximately 60 months
Duration of Response (DOR)
Time frame: Up to approximately 60 months
Number of Participants Treated With Curative Surgical Resection After Chemotherapy
Time frame: Up to approximately 60 months

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing oxaliplatin (OXA), levofolinate calcium (l-LV), 5-FU, panitumumab and oxaliplatin (OXA), levofolinate calcium (l-LV), 5-FU, bevacizumab in people with Colorectal Cancer, run by Takeda at 155 sites in Japan.
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 25 inclusion and 22 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 1 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 155 sites in Japan. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 1 Nov 2023). 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?
OS in Participants With Left-sided Tumors (time frame: Up to approximately 60 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02394795, which also lists 3 linked publications.
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 1 Nov 2023.
