Pluvicto is Approved By Health Canada 

Pluvicto is Approved By Health Canada 

Canada has approved Pluvicto (lutetium (177Lu) vipivotide tetraxetan injection) for the treatment of men with prostate-specific membrane antigen (PSMA) positive metastatic castration-resistant prostate cancer (mCRPC) who have received at least one androgen receptor pathway inhibitor (ARPI) and taxane-based chemotherapy.

Which is Better, 177Lu-PSMA-617 (Pluvicto) or Xofigo (Radium-223)

Which is Better, 177Lu-PSMA-617 (Pluvicto) or Xofigo (Radium-223)

Several men have asked us if they are better off having 177Lu-PSMA-617 (Pluvicto) or Xofigo, a radiopharmaceutical drug that treats bone metastases. There is no simple answer, and the answer is not the same for each of us. Making a sound decision can be helped by understanding the mode of action and the limits of each treatment.

177Lu-PSMA-617 Theranostics Might Be More Active and Safer than Cabazitaxel 

177Lu-PSMA-617 Theranostics Might Be More Active and Safer than Cabazitaxel 

The trial showed that the LuPSMA treatment delayed prostate cancer progression versus Jevtana, with a comparable benefit observed in radiographic progression-free survival and PSA progression-free survival.

Using Radioactive Particles to Kill Cells Attached to a ‘Homing Device’ to Seek Out Cancers

Testing for genetic weaknesses in repairing DNA could pick out men who may benefit from a new type of targeted nuclear medicine, a new study reports.

An emerging class of drugs are made up of a radioactive particle that can kill cells attached to a ‘homing device’ to seek out cancers by detecting the presence of a target molecule on their surface.

Evaluating PSMA-Targeted Radionuclide Therapy

This study did demonstrate that the level of PSMA expression of a man’s prostate cancer, the stronger the association with the likelihood of their having a PSA response. 

Clinical Experience of 100 Consecutive Men Treated with Lu-177 

At the ESMO  2018 Conference that was recently concluded, there was a report of the clinical experience of 100 men with metastatic castrate resistant prostate cancer (mCRPC) who were consecutively treated with Lu-177 PSMA-I&T Radioligand Therapy. 

Results of Phase 2/3 Trial of PSMA PET Imaging Agent PyL for the Detection of Prostate Cancer Spread

Data from the phase 2/3 OSPREY 2301 Study has shown that the PSMA-targeted small molecule PET imaging agent (PyL (18F-DCFPyL) designed to better visualize prostate cancer outside of the gland demonstrated high sensitivity and reliably in detecting distant metastatic prostate cancer lesions and also a high specificity in confirming the absence of pelvic lymph nodes.
