General information about the trial
|
|||
Main objective of the trial |
The primary research objective is to see whether patients taking an aromatase inhibitor in combination with saracatinib have a longer progression free survival (surving without their cancer growing or spreading) than the patients who are taking aromatase inhibitor with placebo.

Arm title

AI plus Saracatinib | ||||||||||||||||||||||||||||||||||||
Arm description |
Patients will receive an aromatase inhibitor and saracatinib (AZD0530). Patients will be enrolled into one of two strata: an “AI-sensitive/naïve” group of patients with potentially AI-sensitive tumours, and a second “prior-AI” group of women whose cancers have already progressed on an AI, but for whom there is likely to still be some endocrine sensitivity. For women in the “AI-sensitive/naïve” group, treatment would be with anastrazole 1mg daily plus saracatinib 175 mg daily. For women in the “prior AI” group, treatment would be exemestane 25mg daily plus saracatinib 175 mg daily. Saracatinib (AZD0530) is an oral Src inhibitor and can be administered with or without food. | ||||||||||||||||||||||||||||||||||||

Dosage and administration details |
175 mg daily, with or without food. If a patient forgets to take a tablet, and it is within 6 hours of the scheduled time then the patient should be advised to take them as soon as possible. If it is more than 6 hours after the scheduled time, then study medication should not be taken for that day. Study medication should continue as scheduled previously on the subsequent day. A patient should not take more than a single day’s dose of tablets, within a day. In the event that the patient cannot hold the tablet(s) down (if the patient vomits) within 30 minutes from taking the tablet(s) or if can identify the tablet (s) in the vomit content, the patient can re-take new tablet(s) from the bottle(s).

Efficacy (progression free survival) | ||||||||||||
End point description |
Comparison of progression free survival between cohort receiving aromatase inhibition plus saracatinib, versus those receiving aromatase inhibition plus placebo.
The duration of progression-free survival (PFS) is measured as the time from randomisation to the time that confirmed progression or death from any cause is documented (whichever comes first). Patients who neither progress nor die are censored at the date they were last known to be alive and progression free.

Reporting group description |
Patients will receive an aromatase inhibitor and saracatinib (AZD0530). Patients will be enrolled into one of two strata: an “AI-sensitive/naïve” group of patients with potentially AI-sensitive tumours, and a second “prior-AI” group of women whose cancers have already progressed on an AI, but for whom there is likely to still be some endocrine sensitivity. For women in the “AI-sensitive/naïve” group, treatment would be with anastrazole 1mg daily plus saracatinib 175 mg daily. For women in the “prior AI” group, treatment would be exemestane 25mg daily plus saracatinib 175 mg daily. Saracatinib (AZD0530) is an oral Src inhibitor and can be administered with or without food. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
