According to data from the Spanish Association against Cancer (AECC) observatory, breast cancer is the second most common type of cancer in Spain with 33,307 new cases in 2019. The number of deceased has reached 6,689 this year. Many research groups are exploring new ways to fight against this disease.
Dasatinib, an FDA-approved compound for the treatment of chronic myeloid leukemia, has become a potential candidate for the treatment of other cancers. It has been recently demonstrated that it could have a relevant role in breast cancer therapy. However, the solubility of this compound is extremely low, leading to poor absorption by the organism. Thus, the administration of a higher dosage is needed in order to obtain a better effect.
An alternative solution to enhance its therapeutic effect is the development of polymeric nanoparticles for a sustained and controlled delivery of the drug.
