The objectives of this study were to determine if clinical trials in breast cancer, with an investigational drug, created direct drug cost savings for the healthcare system related to cost avoidance of the best standard of care treatments used in these studies. The aim was to quantify this potential drug cost avoidance. We conducted a retrospective observational study of the drug cost avoidance during the study period (2014-2016). We included clinical trials with investigational drug, managed by pharmacy department and provided by the sponsor. The patients included had a therapeutic alternative defined as standard treatment that should have been received in case of not participating in the clinical trial. Direct cost savings, to national healthcare system, associated to clinical trials were calculated. Thirty-seven clinical trials with a total of 89 breast cancer patients were included in the study. A total of 62.2% were phase III and 75.7% belonged to the pharmaceutical industry. They provided a total cost avoidance of 957,246€ (1,130,028$), an average cost avoidance per patient of 10,756€ (12,697$). Our study suggests that those clinical trials in which investigational drug are provided or refunded by the sponsor provide substantial cost savings. Due to the shortage of published articles that calculate the cost avoided in medication, we cannot compare directly the results obtained in the different institutions.
