How effective is Alpelisib in the treatment of ovarian cancer?

In the context of the continuous development of precision medicine, Alpelisib-Piqray, as a PI3Kα targeted inhibitor, is often concerned by patients for its indications and potential applications, especially in some tumor types that also have abnormalities in the PI3K pathway, such as ovarian cancer. However, judging from the current international authoritative data and approval by drug regulatory agencies, Apelvis is not suitable for the standard treatment of ovarian cancer.

The approved indication of Apelvis is very clear, that is, in combination with fulvestrant, it is used to treat patients with hormone receptor-positive, HER2-negative advanced or metastatic breast cancer with PIK3CA mutation. The applicable population includes postmenopausal women and men. This positioning is based on in-depth research on the biological characteristics of breast cancer, especially the key role of PIK3CA mutations in the endocrine resistance mechanism of this type of breast cancer.

In contrast, the molecular driving mechanism of ovarian cancer is more complex, and its treatment strategies mainly revolve around surgery, chemotherapy, andPARP inhibitors. Although PI3K pathway-related changes can also be detected in some ovarian cancer patients, these changes do not necessarily constitute the main driving factors, and there is insufficient evidence to prove that simply inhibiting PI3Kα can bring stable and reproducible clinical benefits.

Overseas data shows that the application of Apelvis in ovarian cancer is more at the early exploration or theoretical research level. It has not yet formed a mature treatment model, and has not been recommended by mainstream guidelines or regulatory agencies for the treatment of ovarian cancer. Therefore, at this stage, the use of apelvis for ovarian cancer is off-label, with uncertain efficacy and difficulty in assessing risks.

From the perspective of clinical practice, Apelvis should be regarded as a highly precise targeted drug for specific molecular types of breast cancer, rather than a broad-spectrum anti-tumor drug. When patients with ovarian cancer choose treatment options, they should give priority to well-proven treatment pathways and be cautious about unproven targeted drug options under the guidance of professional doctors.
