Permanent Study Closures

As you know, Central Office has been working on a systematic process to help identify and permanently close out trials that have long since closed to accrual, have completed their final analysis, and have been published (or for which there are no plans to publish). Since the Fall of 2008, the Canadian Cancer Trials Group has closed more than 150 phase III and IND trials. All information disseminated to sites to date can be found at the following link:

Today, we are happy to inform you that three additional trials have now been deemed permanently closed -- MA.10, MA.5, and CO.3. To view the memo that was sent to centres on 12 June 2009 informing them of these closures, please use this link

If you have any questions about this, please contact Anna Sadura, Trial Coordination and Conduct Manager, at
