Early data from the LuPIN trial in men with mCRPC

A lot of people are hopeful that treatment with a new form of targeted nuclear radiation therapy — lutetium-177 PSMA 617 (177Lu PSMA) — will be able to significantly extend survival of men with metastatic, castration-resistant prostate cancer (mCRPC) … READ MORE …

How accurate are gallium-68 PSMA PET/CT scans in the “real world”?

A new article in the journal Cancer Imaging has provided us with an interesting set of “real world” data on the accuracy of gallium-68 PSMA PET/CT scans in the management of prostate cancer. … READ MORE …

The major, Switzerland-based, global pharmaceutical company Novartis has just agreed to acquire Endocyte — the developer of both Lu-177- PSMA-617 and Ac-225-PSMA-617, which are in clinical trials for the treatment of advanced forms of prostate cancer. … READ MORE …

Gallium-68 PSMA PET scanning “is a game changer” in prostate cancer

The “game changer” statement above comes from an independent review of the potential value of gallium-86-labeled prostate-specific molecular antigen (68Ga PSMA) PET scanning in the evaluation of selected men with prostate cancer. … READ MORE …

Progenics reports outcome of OSPREY 2301 trial of PyL™

In a media release issued earlier this morning, Progenics Pharmaceuticals has announced the outcome of a Phase II/III trial of their proprietary, PSMA-targeted imaging agent PyL (also known as 18F-DCFPyL) for identification of prostate cancer. … READ MORE …

Gallium-68 PET/CT scans prior to first-line treatment of some men with prostate cancer

A newly-reported set of data from an Australian clinical research team has now shown that 68Ga PSMA PET/CT scans changed the staging and the management of men after initial diagnosis and prior to first-line treatment compared to traditional CT and bone scanning. … READ MORE …

Trial of new imaging agent nears completion

Early this morning, Progenics Pharmaceuticals announced completion of enrollment of patients in the Phase II/III OSPREY trial of a new PSMA-targeted PET/CT imaging agent for detection of prostate cancer. … READ MORE …

A PSMA-based PET scan can change SRT decisions

The new PSMA-based PET scans provide a way to locate exactly where the cancer has spread to after an unsuccessful prostatectomy. … READ MORE …

Ac-225-PSMA-617 in mCRPC: an update

We now have some details from clinical trials of the radiopharmaceutical actinium-225-PSMA-617 (Ac-225-PSMA-617) in very advanced prostate cancer patients. … READ MORE …

Use of mpMRI and PSMA PET/CT to aid in salvage radiation decision-making

Because the success or failure of salvage radiation (SRT) hinges upon whether micrometastases are already systemic at the time of treatment, evidence that the cancer is still local improves the odds that SRT will be successful. … READ MORE …

Radio-guided surgery in the treatment of recurrent, initially localized prostate cancer

The re-treatment of patients with recurrent prostate cancer after initial, first-line treatment for what was initially diagnosed as localized disease can be complicated. Success (i.e., effective re-treatment with curative intent) in the re-treatment of such patients is often dependent on the ability to identify exactly where recurrence has occurred. … READ MORE …

Does Lu-177-PSMA-617 increase survival?

We have enthusiastically reported the encouraging outcomes of the early clinical trials of the radiopharmaceutical Lu-177-PSMA, most recently at this link. Based on reduction in PSA levels, it performs well. But medicines have no real benefit if all they do is treat PSA. We want medicines that increase survival. … READ MORE …
