Cabozantinib Plus Atezolizumab Delays Progression in mCRPC
SAN FRANCISCO — In patients with metastatic castration-resistant prostate cancer (mCRPC) whose disease progressed on a novel hormonal therapy, the combination of cabozantinib (Cabometyx) plus atezolizumab (Tecentriq) improved radiographic progression-free survival (rPFS) versus a switch to a second hormonal agent, a phase III trial showed. The so-called CONTACT-02 study included patients with extrapelvic nodal or […]
Radionuclide Therapy Tops AR-Pathway Inhibitor Switch for mCRPC
MADRID — Radiographic progression-free survival (rPFS) in metastatic castration-resistant prostate cancer (mCRPC) doubled when patients received a radionuclide ligand targeting prostate-specific membrane antigen (PSMA) instead of switching to another androgen receptor pathway inhibitor (ARPI), a randomized trial showed. In patients with prior progression on an ARPI, median rPFS increased from 5.9 months with another ARPI […]
FDA Staff Not Sold on Broad Olaparib Indication in Metastatic CRPC
Olaparib (Lynparza) plus abiraterone (Zytiga) as initial treatment for metastatic castration-resistant prostate cancer (CRPC) is only clearly effective in patients with BRCA mutations, FDA staff contended in a briefing document released ahead of an advisory committee meeting. On Friday, the FDA is asking its Oncologic Drugs Advisory Committee (ODAC) to weigh in on whether a […]
FDA Approves First Targeted Radioligand Therapy for Metastatic Prostate Cancer
On Wednesday, the FDA approved the first targeted therapeutic radioligand for progressive, metastatic castration-resistant prostate cancer (mCRPC) with prostate-specific membrane antigen (PSMA) expression. Consisting of a targeting compound and a therapeutic radioisotope, lutetium Lu 177 vipivotide tetraxetan (Pluvicto) hones in on PSMA-expressing mCRPC, as identified by a companion diagnostic test (gallium Ga 68 Gozetotide injection, […]
Enzalutamide Rechallenge Yields Small PFS Boost in Metastatic Prostate Cancer
In patients with metastatic castration-resistant prostate cancer (CRPC) who have progressed on enzalutamide (Xtandi), those who continued the treatment in combination with docetaxel and prednisolone saw improved progression-free survival (PFS), the phase IIIb PRESIDE study found. Median PFS was 9.53 months with the the enzalutamide-based combination compared with 8.28 months in those treated with placebo […]
Another PARP Inhibitor Active in BRCA-Mutant Prostate Cancer
A third of patients with previously treated BRCA-mutant metastatic castration-resistant prostate cancer (mCRPC) responded to the PARP inhibitor niraparib (Zejula), a prospective phase II study showed. The results showed that 26 of 76 patients with measurable disease had objective responses, 35 of whom had at least a 30% decrease in tumor size. An exploratory analysis […]
