pralsetinib, as a novel selective RET inhibitor, provides a new treatment option for various cancer patients caused by RET gene mutations. Its high selectivity and specificity enable drugs to inhibit cancer cell proliferation while minimizing their impact on normal cells, thereby improving the safety and effectiveness of treatment.
Pralsetinib has good overall safety, but may also cause some adverse reactions such as rash, difficulty breathing, fatigue, loss of appetite, etc. These reactions are mostly tolerable and relieved after discontinuation or dose adjustment.
