Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Study population: Participants with endocrine-resistant, PIK3CA-mutated, HR+, HER2-, LA/mBC, following on or after completing adjuvant endocrine therapy in routine clinical practice in China.
Who may be able to join
- Participants must be diagnosed with endocrine-resistant, PIK3CA-mutated, HR+/HER2- LA/mBC, following recurrence on or after completing adjuvant endocrine therapy
- Participants must receive the treatment of inavolisib for the first time
- PIK3CA mutation status should be detected by a National Medical Products Administration (NMPA)-approved or validated assay [Polymerase Chain Reaction (PCR) or Next Generation Sequencing (NGS)] by testing of blood or tumor tissue prior to the initiation of inavolisib
Who cannot join
- Participants for which the treatment with inavolisib is not indicated per prescribing information. If the participant starts palbociclib and fulvestrant first, and starts inavolisib after getting a PIK3CA mutation-positive test result later, the palbociclib and fulvestrant will not be deemed as a different line of therapy. However, the medical order of PIK3CA mutation test must be made before or at the same time with the prescription of palbociclib and fulvestrant
- Participants not receiving treatment for LA/mBC with inavolisib according to standard of care (SOC) and in line with the current summary of product characteristics (SPC)/local labeling
- At the investigator's discretion, any reason that makes the participant hard to follow up or unsuitable to participate in the study
