The potential of MVA-5T4 as treatment for advanced prostate cancer

Early data have suggested that a modified vaccinia Ankara (MVA) virus that expresses a tumor-associated glycoprotein called 5T4 may have activity in the treatment of men with metastatic, castration-resistant prostate cancer (mCRPC) — among other forms of cancer. We will refer to this agent as MVA-5T4; the brand name is TroVax®.

Potential future agents in the management of mCRPC

A new article by Antonarakis and Armstrong in full text on the Medscape web site reviews available information on a wide range of currently investigational agents for the treatment of metastatic, castration-resistant prostate cancer (mCRPC), including

Does eribulin mesylate have potential in mCRPC … or not?

In May 2010 we reported that a product called eribulin mesylate had been tested (in the USA) in a Phase II clinical trial for its activity in metastatic, castration-resistant prostate cancer (mCRPC) — and that the results were not particularly promising.

New options after standard hormone therapy has failed

We apparently managed to overlook a series of three review and commentary articles published in Oncology in May this year that dealt with the evolving options that have already — or will soon — come available for the treatment of castration-resistant prostate cancer (CRPC).

Abiraterone acetate treatment affects fatigue in men with mCRPC

According to a retrospective analysis of data from a randomized, double-blind, Phase III clinical trial, abiraterone acetate (Zytiga™) can significantly lower levels of fatigue in men with metastatic, castration-resistant prostate cancer (as well extending survival).

Oncothyreon enrolls first patient in Phase II trial of PX-866 for CRPC

Oncothyreon, Inc. has announced initiation of a Phase II clinical trial of the company’s investigational agent PX-866 in the treatment of men with chemotherapy-naïve, recurrent or metastatic, castration-resistant prostate cancer (CRPC).

Combining a TKI with bicalutamide in men with CRPC

We have reported on a number of attempts to use tyrosine kinase inhibitors (TKIs) — alone or in combination with chemotherapy — in the treatment of men with castration-resistant prostate cancer (CRPC). Limited activity or efficacy has been reported to date.

Can CTC levels predict progression of hormone-sensitive prostate cancer?

The levels of circulating tumor cells (CTCs) — as evaluated using Cellsearch technology — is becoming accepted as a prognostic marker for disease progression among men with  metastatic castration-resistant prostate cancer (mCRPC), and may even be accepted soon as a surrogate marker for prostate cancer-specific mortality in clinical trials of new agents.

Alpharadin shows 2.8-month survival benefit in mCRPC

The investigational radioisotope radium-233 chloride (Alpharadin) has shown a small but clinically significant overall survival benefit in the treatment of men with symptomatic, metastatic, castration-resistant prostate cancer (mCRPC).
