Alas … once again we hear that the combination of  androgen receptor blockade (with enzalutamide/Xtandi) + a checkpoint inhibitor (the PD-L1 inhibitor atezolizumab/Tecentriq) has had no clinically meaningful impact on the overall survival (OS) of men with metastatic, castration-resistant prostate cancer (mCRPC) compared to enzalutamide alone. … READ MORE …

Talazoparib + enzalutamide in treatment of mCRPC

Back in December 2017, Pfizer started a trial to explore whether the PARP inhibitor talazoparib (Talzenna) could be used in combination with enzalutamide (Xtandi) to effectively treat men with what are known as MSI-H or dMMR subtypes of metastatic castration-resistant prostate cancer (mCRPC). … READ MORE …

Is there a subset of CRPC patients who may respond well to checkpoint inhibition?

A paper in the journal Oncotarget has suggested that patients who have progressed on treatment with enzalutamide (Xtandi) may be good candidates for treatment with one of the checkpoint inhibitors like pembrolizumab (Keytruda), nivolumab (Opdivo), or even ipilimumab (Yervoy). … READ MORE …
