Brief summary

Diarrhoea is the most commonly reported adverse event (AE) associated with Lapatinib treatment, and is also commonly associated with Capecitabine treatment. Although these events are generally mild to moderate in severity, diarrhoea adversely affects the tolerability of cancer treatment, and in severe cases diarrhoea has the potential to affect the efficacy of treatment due to poor compliance, or treatment interruption or withdrawal. The efficacy of Octreotide in the management of cancer treatment-associated diarrhoea has not been extensively evaluated in large, well-controlled studies. This is a randomised, multi-centre, open-label Phase II study in subjects with Human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer which has progressed following prior therapy, which must have included anthracyclines and taxanes and therapy with Trastuzumab in the metastatic setting. This study is not placebo controlled, and there is no active comparator. The study evaluates whether the prophylactic use of Octreotide Long Acting Release (LAR) offers a clinically meaningful benefit by reducing the frequency and severity of diarrhoea associated with treatment with Lapatinib and Capecitabine. Study completion for a subject is defined as the completion of 24 weeks of treatment with Lapatinib and Capecitabine, or progression of cancer or the death of the subject during treatment, whichever occurs first. Approximately 140 subjects were planned to be randomized out of which 70 were planned to receive octreotide and 70 were planned to receive no Octreotide.

Interventions

DRUGLapatinib

Lapatinib was supplied as 250mg tablets that are oval, biconvex, and orange film-coated with one side plain and the opposite side debossed, or as 250mg tablets that are oval, biconvex, and yellow film-coated with one side plain and the opposite side debossed. Each tablet contained 405mg of Lapatinib ditosylate monohydrate, equivalent to 250mg Lapatinib free base

DRUGCapecitabine

Capecitabine (Xeloda™) was supplied as a biconvex, oblong, light peach or peach colored film-coated tablet for oral administration. Each light peach colored tablet contained 150mg Capecitabine and each peach colored tablet contained 500mg Capecitabine. Generic versions of capecitabine may have been used within the study if Xeloda cannot be provided. XELODA™ is a trademark of Hoffmann-La Roche AG.

DRUGOctreotide

Octreotide (Sandostatin LAR™) was supplied as sterile 5milliliter (mL) vials delivering 20mg Octreotide as the free peptide. When mixed with diluent (approximately 2mL or 2.5 mL) it becomes a suspension that is given as an intramuscular injection. Two 20mg intramuscular injections were given to deliver a total dose of 40mg. The Octreotide is uniformly distributed within the microspheres which are made of a biodegradable glucose star polymer, D,L-lactic and glycolic acids copolymer. Sterile mannitol was added to the microspheres to improve suspendability
