Pharmacotherapeutic options for cancer cachexia: emerging drugs and recent approvals

The lack of effective therapeutic approaches against cachexia results from several issues, among which a reduced number of studies focused on new drugs. Furthermore, the translation of pre-clinical results in the clinical practice is a hard mission, and it must be considered whether drugs target cachexia as a consequence of acting directly on the tumor. Indeed, dissecting antineoplastics from direct anti-cachexia effects is needed to elucidate the mechanisms of action of specific drugs. This is necessary for their inclusion into multimodal approaches, which nowadays are considered the best way to tackle cachexia.
