Pharmacotherapeutic options for cancer cachexia: emerging drugs and recent approvals

Introduction: Cachexia is a complex multi-factorial syndrome characterized by anorexia, inflammation, body, and skeletal muscle wasting. Early diagnosis and intervention via a multimodal approach combining nutritional counseling, exercise, and pharmacological agents is advisable. However, no effective treatment options are currently available in the clinical setting.

Expert opinion: 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-...
