ABSTRACT
Most patients that die from cancer do not die due to the primary tumor but due to the development of metastases. However, there is currently still no drug on the market that specifically addresses and inhibits metastasis formation. This lack was, in the past, largely due to the lack of appropriate screening models, but recent developments have established such models and have provided evidence that tumor cell migration works as a surrogate for metastasis formation. Herein we deliver on several examples a rationale for not only testing novel cancer drugs by use of these screening assays, but also reconsider established drugs even of other fields of indication.
ABSTRACT
As the number of novel drugs that have entered the market in oncology has slowed in recent years, there has been a dramatic shift towards new therapeutic approaches. The majority of cancer patients die from metastasis formation, which has prompted the pharmaceutical industry to begin to investigate a new class of agents: anti-metastatics. This review provides an overview of the targets, mechanisms of action, and drug substances currently in the pharma pipeline to inhibit tumor cell migration and metastasis formation.
