Patient case: 35-year-old female with Breast cancer. Genetic variant: NRAS Amplification. Other conditions: None.

Clinical trial: A Phase III Clinical Trial to Evaluate Patient´s Preference of Subcutaneous Trastuzumab (SC) Versus Intravenous (IV) Administration in Patients With HER2 Positive Advanced Breast Cancer (ABC).

Summary: GEICAM/2012-07 is a study phase III, prospective, open, randomized, multicenter and national designed to assess patient preference for intravenous (IV) or subcutaneous (SC) of trastuzumab, and within the SC by the administration through the vial or device self-administration in patients with disseminated breast cancer HER2.
  Approximately 195 patients will be included to receive subcutaneous trastuzumab a fixed dose of 600 mg every 3 weeks for 4 cycles (2 administered from the injection of a vial with a syringe and 2 with the injection device). Following administration of these four cycles, the patient will decide whether or not to continue with the subcutaneous formulation of trastuzumab every 3 weeks until progression. Since the randomization in the study until the start with subcutaneous trastuzumab, patients will receive a treatment cycle of intravenous trastuzumab as usual.
  Main objective: Proportion of patients indicate a preference for the use of subcutaneous vs intravenous trastuzumab.
  This principal primary objective will be analyzed with the answers to questionnaire of experiences and preferences of the patients (Principal endpoint) The duration of the study has been estimated after 34 months.


Eligibility: Inclusion Criteria:
