PIK3CA act mut | triple-receptor negative breast cancer | no benefit | Ipatasertib + Paclitaxel | Phase II | Actionable | In a Phase II trial (LOTUS), Ipatasertib (GDC-0068) in combination with Abraxane (paclitaxel) resulted a median progression free survival of 6.2 vs 4.9 months with placebo in triple-receptor negative breast cancer patients harboring activating mutations in PIK3CA or AKT1, or inactivating mutations in PTEN (PMID: 28800861; NCT02162719). | 28800861 |
PIK3CA act mut | triple-receptor negative breast cancer | no benefit | Ipatasertib + Paclitaxel | Phase III | Actionable | In a Phase III trial (IPATunity130), the addition of Ipatasertib (GDC-0068) to treatment with Abraxane (paclitaxel) did not result in improved median progression-free survival (7.4 mo vs 6.1 mo, HR=1.02, p=0.92), median overall survival (24.4 mo vs 24.9 mo, HR=1.08), objective response rate (39% vs 35%) or clinical benefit rate (47% vs 45%) in patients with metastatic triple-negative breast cancer harboring PIK3CA and/or AKT activating mutations or PTEN inactivating mutations (PMID: 39058425; NCT03337724). | 39058425 |
