The breast cancer pipeline is the largest in the pharmaceutical industry, with 1,050 products in active development across all stages. The range of mechanisms of action employed by these compounds is also highly diverse, especially in comparison to the existing market landscape. The degree and proportion of breakthrough innovations in this pipeline is exceptional – GBI Research analysis identified 333 first-in-class programs in the breast cancer pipeline, acting on 251 first-in-class molecular targets. This accounts for some 39% of all products with a disclosed molecular target, and is reflective of the high degree of innovation in this indication. This has far-reaching strategic implications for all market participants, as despite the high attrition rate in breast cancer, it is highly likely many of the first-in-class products will reach the market over the coming decade and, will have the opportunity to transform the clinical and commercial landscape.
