Introduction to the main indications and clinical application scope of Talazoparib (Tazena)

Talazoparib is an oral PARP inhibitor, mainly used for breast cancer patients carrying BRCA1 or BRCA2 gene mutations, especially HER2 negative, locally advanced or metastatic breast cancer patients. It inhibits the activity of polyADPribose polymerase (PARP), blocks the cancer cellDNA repair pathway, induces the accumulation of DNA damage, and thereby promotes tumor cell apoptosis. This mechanism of action enables Talazoparib to show significant efficacy in patients carrying BRCA mutations, making it one of the important options for targeted therapy.

In terms of clinical application, talazoparib is mainly suitable for patients with breast cancer who have received poor response to chemotherapy or have relapsed. Multiple clinical studies have shown that the use of talazoparib in patients with BRCA mutations can significantly extend progression-free survival and improve the overall response rate (ORR). Compared with traditional chemotherapy, oral talazoparib can reduce damage to normal cells, has relatively controllable side effects, has high patient compliance, and is suitable for long-term maintenance treatment.

In addition, talazoparib is also being explored in other solid tumors, such as ovarian cancer and prostate cancer. For patients harboring BRCA mutations or defects in homologous recombination repair (HRR), talazoparib may provide therapeutic benefit through a similar DNA repair inhibition mechanism. Clinical trials have shown that in patients with these specific genetic backgrounds, Talazoparib can reduce tumor volume, improve symptoms, and delay disease progression, providing a potential option for precision treatment.

When usingTalazoparib, attention should be paid to individualized treatment and safety management. Common adverse reactions include anemia, thrombocytopenia, leukopenia, fatigue and nausea, most of which can be controlled through dose adjustment or supportive treatment. Before treatment, genetic testing should be performed to confirmBRCA mutation status, and to evaluate liver and kidney function and hematological indicators. Through standardized use, monitoring and follow-up,Talazoparibcan ensure efficacy while minimizing risks, providing effective targeted treatment options for patients with BRCA mutated breast cancer and related tumors.
