Abiraterone | Zytiga | CB7630 | Hormone - Anti-androgens 54 | Zytiga (abiraterone) inhibits cytochrome P-450c17, resulting in decreased androgen synthesis (PMID: 25560485). Zytiga (abiraterone) is FDA approved for patients with metastatic castration-resistant prostate cancer (FDA.gov). |
Ipatasertib | GDC-0068|RG-7440 | Akt Inhibitor (Pan) 21 | Ipatasertib (GDC-0068) binds to and inhibits the activity of AKT in an ATP-competitive manner, which may result in the inhibition of the PI3K-AKT signaling pathway and tumor cell proliferation (PMID: 22934575, PMID: 32205017). |

PTEN loss | castration-resistant prostate carcinoma | sensitive | Abiraterone + Ipatasertib | Phase III | Actionable | In a Phase III trial, Ipatasertib (GDC-0068) combined with Zytiga (abiraterone) significantly improved median radiographical progression-free survival (PFS) (18.5 vs 16.5 mo, HR 0.77, p=0.034) in patients with metastatic castration resistant prostate cancer harboring PTEN loss (by IHC) when compared to placebo combined with Zytiga, median PFS was not improved (19.2 vs 16.6 mo, HR 0.84, p=0.043) in the intent-to-treat population (PMID: 34246347; NCT03072238). | 34246347 |
PTEN loss | castration-resistant prostate carcinoma | sensitive | Abiraterone + Ipatasertib | Phase II | Actionable | In a Phase II trial, the combination of Ipatasertib (GDC-0068) and Zytiga (abiraterone) resulted in a better progression-free survival in metastatic castration resistant prostate cancer patients with PTEN loss (by IHC) when compared to placebo combined with Zytiga (PMID: 30037818; NCT01485861). | 30037818 detail... |
