Evidence Level:Sensitive: A2 - Guideline
Excerpt:Recommendation 1.4...Patients with metastatic triple-negative breast cancer with germline BRCA1 or 2 mutations who have previously been treated with chemotherapy in the neoadjuvant, adjuvant, or metastatic disease setting may be offered an oral poly (ADP-ribose) polymerase (PARP) inhibitor (olaparib or talazoparib) rather than chemotherapy...

Title:
4th ESO–ESMO International Consensus Guidelines for Advanced Breast Cancer (ABC 4)
Excerpt:A PARPi (olaparib or talazaparib) is a reasonable treatment option for patients with BRCA-associated advanced TNBC or luminal (after progression on ET) ABC, previously treated with an anthracycline with/without a taxane (in the adjuvant and/or metastatic setting), since its use is associated with a PFS benefit, improvement in QoL and a favourable toxicity profile.

Title:
Analysis of germline BRCA1/2 mutated (gBRCAmut) hormone receptor-positive (HR+) and triple negative breast cancer (TNBC) treated with talazoparib (TALA).
Excerpt:Of 431 pts randomized, 241 had HR+ BC and 190 had TNBC. ORR for TALA was similar for the 2 groups: 61.8% for TNBC vs 63.2% for HR+. Duration of response median for TALA was longer for HR+ (6.8 months) compared to TNBC (4.3 months); both groups included a subset with a prolonged response to TALA...Talazoparib demonstrated improved PFS and ORR in pts both with gBRCAmut HR+ BC and TNBC.
