I wonder if someone could give us a summary of what has been done in this area, as I am finding it difficult to differentiate between the different studies completed, ongoing and planned! If someone could just summarise the following, I'd be grateful: What studies have been completed. What has been published. What is ongoing. What is finished but not yet published. What is planned for the future. In each could you mention the number of patients, type of treatment and outcome. Thanks!
