Exploring the clinical trials, regulatory insights, and challenges of PROTACs in oncology

While various targeted therapies exist for cancer, resistance mechanisms remain a significant challenge. Recent advancements in cancer treatment have led to the emergence of proteolysis-targeting chimeras (PROTACs), a promising technology utilizing hetero-bifunctional molecules to target and degrade proteins implicated in cancer progression through the ubiquitin-proteasome system (UPS). PROTACs offer a novel approach, with recent studies and clinical trials demonstrating promising outcomes in degrading endogenous proteins linked to cancer. This work explores classification, regulatory approvals, and ongoing clinical trials of PROTAC technology in cancer management. It emphasizes the importance of regulatory compliance to expedite approvals from relevant authorities. It also highlights challenges and opportunities associated with their implementation. Despite these preliminary efforts, PROTACs show immense potential in effectively addressing cancer. Their ability to target specific proteins for degradation represents a significant advancement in cancer therapeutics, offering new hope for improved outcomes in patient care.
