About this study

Official title: CONCEPT - Phase IV, Randomized, Prospective, Multicenter Comparison of Intermittent Schedule of Oxaliplatin Combined With FOLFOX/Bevacizumab vs Conventional Mode of Administration of FOLFOX/Bevacizumab + Neuroprophylaxis With Calcium/Magnesium for Optimization of First-Line Therapy of Metastatic Colorectal Cancer

The primary rationale for this study is to develop an optimized schedule of administration of FOLFOX + bevacizumab that maximizes the efficacy and safety of this regimen when administered to patients with advanced colorectal cancer. The hypothesis is that the use of an intermittent oxaliplatin (IO) schedule of FOLFOX/bevacizumab will allow these patients to continue on treatment for a longer period of time by reducing the proportion of patients who discontinue therapy early because of treatment-related toxicities and thus increasing the possibility of a longer time to progression.

The primary objective is:

  • To test the hypothesis that an intermittent oxaliplatin (IO) schedule of FOLFOX/bevacizumab will allow patients to remain on therapy for a longer period of time compared to a conventional "treat-to-failure" schedule, by reducing the proportion of patients who discontinue therapy for treatment-related toxicities.

The secondary objectives are:

  • To evaluate the impact of calcium/magnesium infusions on the incidence and severity of neurotoxicity in subjects receiving either the IO or conventional FOLFOX/bevacizumab treatment schedules as first-line treatment for metastatic colorectal cancer.
  • To evaluate the safety and efficacy of the IO versus the conventional schedule + calcium and magnesium infusions, as part of oxaliplatin-based first-line therapy for metastatic colorectal cancer.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to treatment failure (TTF) for the conventional oxaliplatin (CO) schedule in comparison with the intermittent oxaliplatin (IO) schedule

Secondary outcomes (7)
  1. The incidence of adverse events, including neurotoxicity, as determined using the National Cancer Institute (NCI) Common Toxicity Criteria version 3.0 (CTCAE v3.0)

  2. Quality of life, including oxaliplatin-specific neurologic symptoms determined using the PNQoxali

  3. Tumor response rate (overall and confirmed) based on application of the Response Evaluation Criteria in Solid Tumors (RECIST)

  4. Time to tumor progression (TTP)

  5. Time of tumor control (TTC)

  6. Overall survival (OS)

  7. Reasons for treatment discontinuation

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted12 Aug 2005 (estimated)
  2. Study startFeb 2005
  3. Study completionDec 2007

Why it stopped: Unplanned interim analysis by DSMB indicated possible reduced response rate with the addition of Ca/Mg in pooled population. Further analysis pending.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing oxaliplatin in people with Colorectal Cancer, run by Sanofi at 1 site in United States.

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 4 inclusion and 10 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: stopped early, as of the sponsor's last update on 13 Feb 2009. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Unplanned interim analysis by DSMB indicated possible reduced response rate with the addition of Ca/Mg in pooled population. Further analysis pending.). Results are not available in the source record.

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?

Time to treatment failure (TTF) for the conventional oxaliplatin (CO) schedule in comparison with the intermittent oxaliplatin (IO) schedule. 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 13 Feb 2009.
