Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Group 1: Best supportive care plus BBI608. Best supportive care defined as those measures designed to provide palliation of symptoms and improve quality of life as much as possible. BBI608 will be self-administered by participants at 480mg (6 x 80mg tablets) orally twice daily (960mg total daily dose) in 28 day cycles. Patients may continue to receive protocol therapy as long as they have not experienced any adverse events requiring permanent discontinuation of study medication and are, in the opinion of the investigator, continuing to derive benefit from protocol therapy.

Patients will be asked to keep a diary of when they take the capsules and if they miss any doses to monitor adherance. Patients will also be asked to return any tablets which were not taken.

Group 2: Best supportive care plus Placebo. Best supportive care defined as those measures designed to provide palliation of symptoms and improve quality of life as much as possible. The matched placebo will be self-administered by participants at 480mg (6 x 80mg tablets) orally twice daily (960mg total daily dose) in 28 day cycles. Patients may continue to receive protocol therapy as long as they have not experienced any adverse events requiring permanent discontinuation of study medication and are, in the opinion of the investigator, continuing to derive benefit from protocol therapy.

Summary
Brief summary
This study will evaluate the effect of a drug called BBI608, a cancer stem cell inhibitor, for treatment of advanced colorectal cancer.
Who is it for?
You may be eligible to join this study if you are aged 18 years or above and have been diagnosed with advanced colorectal cancer for which no further standard anticancer therapy is appropriate or available.
Trial Details:
Participants in this trial will be randomly (by chance) allocated to one of two groups. Participants will either take BBI608 (Group 1) or a placebo (sham) (Group 2) tablets twice per day in continuous 28 day cycles. Treatment will continue for as long as they have not experienced any adverse events requiring permanent discontinuation of study medication and are, in the opinion of the investigator, continuing to benefit from therapy. Participants will not know whether they are taking BBI608 or the placebo until after the trial is completed. Participants will be followed up every 4 weeks in order to evaluate how they are responding to treatment.
