Breast cancer prevention

One in eight women will develop breast cancer over the course of her lifetime. In 2014, over 1.2 million women where affected worldwide, making breast cancer the most frequent cancer type in women.(Globocon 2012)

The small molecule drug candidate DB1RA aims to prevent the onset of breast cancer development in healthy high-risk patients, by blocking the Neurokinin-1 (NK-1) receptor. This blockage leads to the inhibition of cell proliferation and migration, and to the induction of apoptosis. The drug is safe, well tolerated, and already approved for the treatment of nausea and vomiting.

The first preclinical results with DB1RA are very promising.

The substance P/NK-1 receptor system: NK-1 receptor antagonists as anti-cancer drugs

The substance P (SP)/neurokinin (NK)-1 receptor system plays an important role in cancer. SP promotes the proliferation of tumour cells, angiogenesis and the migration of tumour cells. We review the involvement of SP, the NK-1 receptor and NK-1 receptor antagonists in cancer. Tumour cells overexpress NK-1 receptors, which are involved in their viability. This overexpression suggests the possibility of specific treatment against tumour cells using NK-1 receptor antagonists, thus promoting a considerable decrease in the side effects of the treatment. This strategy opens up new approaches for cancer treatment, since these antagonists, after binding to their molecular target, induce the death of tumour cells by apoptosis, exert an antiangiogenic action and inhibit the migration of tumour cells. The use of NK-1 receptor antagonists such as aprepitant (used in clinical practice) as antitumour agents could be a promising innovation. The value of aprepitant as an antitumour agent could be determined faster than for less wellknown compounds because many studies addressing its safety and characterization have already been completed. The NK-1 receptor may be a promising target in the treatment of cancer; NK-1 receptor antagonists could act as specific drugs against tumour cells; and these antagonists could be new candidate anti-cancer drugs.
