Julian Beach, Interim Executive Director of Healthcare Quality and Access at the MHRA, emphasized the clinical significance of this approval: "The approval of inavolisib provides a new targeted treatment for people with advanced breast cancer (搜索) that has returned or spread after hormone therapy. Inavolisib can help delay the progression of the disease, giving patients more time with effective treatment."
Safety Profile and Monitoring
The most common side effects associated with inavolisib include high blood sugar, inflammation of the mouth (stomatitis), diarrhea, tiredness, anemia, nausea, decreased appetite, rash, headache, weight loss, vomiting, and urinary tract infections.

The medicine is subject to additional monitoring to enable rapid identification of new safety information. Beach noted that "as with all licensed medicines, we will continue to monitor its safety and effectiveness closely as it becomes more widely used."
Regulatory and Safety Reporting
Patients experiencing side effects are encouraged to consult their doctor, pharmacist, or nurse. The MHRA emphasizes the importance of reporting suspected adverse reactions through the Yellow Card scheme, available via website or mobile app, to maintain continuous monitoring of the treatment's benefit-risk balance.
