Current Primary Outcome Measures (submitted: June 11, 2021)

Duration of Disease Control (DDC) [ Time Frame: From baseline until end of strategy; up to 80 months after the beginning of the study ]

DDC is defined as the sum of PFS of each active treatment course planned in the treatment strategy. DDC excludes 1) intervals between disease progression and re-initiation of treatment, and 2) PFS of inactive treatment if PD occurs at first evaluation after treatment re-initiation (either reintroduction in a stop-and-go strategy or subsequent course of treatment in a multi-line strategy).

• Original Primary Outcome Measures (submitted: July 25, 2013): Duration of Disease Control [ Time Frame: From baseline until end of strategy, assessed up to 80 months after the beginning of the study ]

Current Secondary Outcome Measures (submitted: June 11, 2021)

• Assessment of Quality of life (QoL) [ Time Frame: From baseline until end of strategy; up to 80 months after the beginning of the study ]
  QoL will be considered to be improved if at least one time to QoL score deterioration (5 targeted dimensions) will be significantly longer without a significant shorter time to QoL score dimensions for other 4 targeted dimensions.
• Overall Survival (OS) [ Time Frame: Up to 80 months after the beginning of the study ]
  Time from randomization to the date of death from any cause
• Time to Failure of Strategy (TFS) [ Time Frame: Up to 80 months after the beginning of the study ]
  TFS is defined as beginning with the initiation of the strategy under investigation and ending with the first of the following events: 1) death, 2) disease progression on the last received planned sequence, 3) patient requires the addition of a new (unplanned) therapeutic agent, 4) patient experiences disease progression during a partial or complete break in therapy from initial treatment strategy and receives no further therapy within one month.
• Progression-free survival (PFS) per sequence of therapy [ Time Frame: Up to 80 months after the beginning of the study ]
  Time from randomization to the date of first documented disease progression or death from any cause, whichever occurs first.
• Tumor Response Rate (RR) [ Time Frame: From baseline until end of strategy; up to 80 months after the beginning of the study ]
  Tumor response will be assessed using RECIST version 1.1 per sequence of therapy
• Curative salvage surgery rate [ Time Frame: From baseline until end of strategy; up to 80 months after the beginning of the study ]
  The number of patient with R0 and R1 curative salvage surgery will be assessed globally (per arm) and per sequence of therapy
• Safety profile of each treatment sequence [ Time Frame: From study entry to 1 month after last study drug administration; up to 80 months after the beginning of the study ]
  The report will take into account all adverse events observed during and after drug administration, including any adverse events that may be related to the administration procedure itself.

• Official Title: Multi-Line Therapy Trial in Unresectable Wild-Type RAS Metastatic Colorectal Cancer. A GERCOR Randomized Open-label Phase III Study.
• Brief Summary: STRATEGIC-1 is a study designed to determine the best sequence of therapy in patients with metastatic colorectal cancer.

Detailed Description

This is a phase III study assessing 2 mutli-line therapeutic strategies in patients with unresectable wild-type RAS metastatic colorectal cancer. All the available treatments are being used in each strategy (oxaliplatine, irinotecan, fluoropyrimidines, bevacizumab, cetuximab or panitumumab) but in a different order:

STRATEGY A: FOLFIRI-cetuximab, followed by oxaliplatin-based chemotherapy with bevacizumab vs.

STRATEGY B: OPTIMOX-bevacizumab, followed by irinotecan-based chemotherapy with bevacizumab, followed by anti-EGFR mab with or without irinotecan.
