A Study of Capecitabine Rapid Disintegrating Tablets (RDT) Versus Commercial Xeloda in Patients With Solid Tumours

This randomized, open-label, two-way crossover study will evaluate the relative bioavailabilty and safety of capecitabine rapid disintegrating tablets (RDT) versus commercial Xeloda tablets in patients with colorectal or breast cancer.
