AstraZeneca Korea launched Truqap, the first AKT inhibitor for HR+/HER2- breast cancer, targeting PIK3CA, AKT1, or PTEN mutations. Truqap, approved in April, offers new hope for patients progressing after endocrine therapy. The CAPItello-291 study showed Truqap plus fulvestrant doubled median progression-free survival to 7.3 months. Despite financial concerns over NGS costs, global guidelines recommend mutation testing for effective treatment.
