Trial Outcomes & Findings for A Phase 1-2 Trial of Cetuximab in Combination With Oxaliplatin, Capecitabine, and Radiation Therapy Followed by Surgery for Locally-advanced Rectal Cancer (NCT NCT00226941)

NCT ID: NCT00226941

Last Updated: 2017-12-08

Results Overview

Dose-limiting Toxicity (DLT) is the measure used to establish overall Maximum-tolerated dose (MTD) of cetuximab + capecitabine + radiotherapy +/- oxaliplatin. MTD is defined as the highest dose level for which participants have a \< 30% incidence of dose-limiting toxicity (DLT). The outcome is expressed as the number of DLTs by treatment group.

SECONDARY outcome

Timeframe: 12 to 14 weeks after radiotherapy

Population: This outcome is specifically defined per protocol as the phase 2 portion of the study, which did not occur. However, the data for this measure are available from the phase 1 participants (only), and are provided for completeness.

After treatment with capecitabine, cetuximab, radiotherapy, and oxaliplatin, the pathologic response rate was assessed based on the excised tumor taken at the time of surgical resection. Pathologic response rate was determined as the number and proportion of participants who experienced either downstaging of their disease, or complete response (CR, no detectable disease). A participant will be considered to have downstaging of the tumor as a result of the neoadjuvant therapy when the primary tumor (T) stage by pathology isless than the T stage by clinical (endoscopic) evaluation, or when the regional lymph node (N) tumor stage by pathology is less than the N stage by clinical (endoscopic) evaluation.

Timeframe: 12 to 14 weeks after radiotherapy

Population: This outcome is specifically defined per protocol as the phase 2 portion of the study, which did not occur. However, the data for this measure are available from the phase 1 participants (only), and are provided for completeness.

Downstaging means a reduction from the stage of disease observed at baseline to the stage of disease after treatment with cetuximab, radiotherapy, oxaliplatin, and capecitabine, as determined at the time of surgical removal of the tumor. Downstaging may be observed as improvements in tumor staging at the primary site of the tumor; in nearby (regional) lymph nodes; or in metastatic disease beyond the regional lymph nodes. This outcome specifically does not include participants that achieved a complete response, nor those that experienced no response or disease progression.

SECONDARY outcome

Timeframe: 5 years

Population: This study was terminated before all patients reached 5 years from the date of surgical resection. Only patients that progressed are reported, and since no patients progressed in Group 2, median and range are not reportable.

Time-to-progression was assessed as the time from the date of surgical resection to the appearance of either local disease recurrence or distant metastases by any modality (eg, clinical exam, endoscopy, radiographic imaging). All relapses were to be confirmed by biopsy and pathology review.
