• At least 3 weeks since last major surgery;

• At least 12 months since last adjuvant chemotherapy;

• At least 6 weeks since prior radiotherapy providing that the extent and site of radiotherapy fields are such that marked bone marrow suppression is NOT expected;

• Patients who have received palliative radiotherapy must have recovered from any reversible toxic effects e.g. nausea and vomiting caused by radiation of fields;

• Patients with reproductive potential must use effective BC;
