Innovation in cancer therapeutics and regulatory perspectives.

Cancer therapy has undergone a drastic revolution in the past few decades with the introduction of several novel therapies, like immunotherapy (active and passive), stem cell-based therapies, and nanocarrier-based therapies. These therapies have addressed the issues of conventional cancer therapy (chemotherapy or radiotherapy), like specificity and off-target effects. Further, the introduction of such treatments has improved survival and converted a terminal disease into a more manageable condition. However, many clinical, ethical, and regulatory issues are raised with such novel additions. Several effective therapies are under research but could not come to market or are delayed due to regulatory concerns for marketing approval. The scope of this review encompasses the examination of these regulatory issues and discuss their possible solutions. A practical and flexible regulatory approach, harmonized globally, could help the patients suffering from a terminal illness to lead a quality life.
