Abiraterone acetate extends median survival by 3.9 months in mCRPC

The results of a randomized, double-blind, placebo-controlled, multi-center, Phase III clinical trial comparing abiraterone actetate + prednisone to a placebo + prednisone in men with metastatic castration-resistant prostate cancer (mCRPC) were presented today at the annual meeting of the European Society for Medical Oncology in Milan, Italy.

Acid-suppressive therapy + ketoconazole in men with CRPC

Ketoconazole has long been used as a “third-line” agent in men with castration-resistant prostate cancer (CRPC) who have progressive disease after standard forms of hormonal therapy. For some patients, ketoconazole can be clinically effective and cost-effective compared to other clinical options.

Pfizer discontinues Phase III clinical trial of Sutent in CRPC

An announcement yesterday has made it clear that sunitinib malate (Sutent) is unlikely to ever show significant clinical activity in the management of patients with advanced, castration-resistant prostate cancer (CRPC) after initial chemotherapy.

Older (and newer) drugs in the management of CRPC

On his Advanced Prostate Cancer blog site, Joel Nowak has just published a series of five brief articles on the opportunities offered by some older agents that are available for use as second-line therapies in the management of patients who have a rising PSA after treatment with standard forms of androgen deprivation therapy (ADT).

Early stage data on inecalcitol + docetaxel in CRPC

Data from a French firm called Hybrigenics suggest that a new product, inecalcitol, that targets the vitamin D receptor may have clinical activity in combination with docetaxel-based chemotherapy in patients with castration-resistant prostate cancer (CRPC).

Data published from Phase II trial of OGX-011 (custirsen)

Back in 2009 we reported the results of a randomized Phase II trial of docetaxel + OGX-011 vs. docetaxel + placebo as they were initially presented at the annual meeting of the American Society of Clinical Oncology in Chicago (ASCO).

CytRx announces Phase II trial of bafetinib in CRPC

Bafetinib (previously known as INNO-406) is a protein kinase inhibitor that targets two different enzymes. The newly announced trial is designed to investigate the potential of bafetinib in the treatment of men with castration-resistant prostate cancer (CRPC) who have progressive disease after treatment with at least one course of chemotherapy.

Figitumumab + docetaxel in treatment of CRPC

Figitumumab (also known as CP-751,871) is a fully humanized monoclonal antibody designed to target the insulin-like growth factor type 1 receptor (IGF-IR). Data are now available from a very early-stage trial of figitumumab in combination with docetaxel in the treatment of patients with late-stage solid tumors — including castration-resiatant prostate cancer (CRPC).

What’s “bipolar” androgen therapy? How does it work?

Traditional forms of hormone therapy for prostate cancer are based on the idea that you reduce testosterone levels as low as you can so as to stop the ability of testosterone and its metabolites (e.g., dihydrotestosterone) to stimulate growth of prostatic tissues — including prostate cancer cells.

The long-term survival of patients with metastatic prostate cancer

In the late 1980s and early 1990s it was generally considered that men diagnosed with metastatic (but still hormone sensitive) prostate cancer had an estimated survival of 18 to 36 months from the time of diagnosis — including their time on treatment with hormonal therapy.

US FDA approves cabazitaxel for late-stage prostate cancer

Somewhat “out of the blue,” the US Food and Drug Administration (FDA), earlier today, approved Sanofi-Aventis’s “second-generation” taxane, cabazitaxel (Jevtana®) in combination with prednisone for the treatment of men with metastatic, castration-resistant prostate cancer (mCRPC) who have already progressed after treatment with docetaxel.

More about ipilimumab, but not in prostate cancer

One of the really “hot” pieces of news from ASCO today was the result of a Phase III clinical trial of ipilimumab in a form of metastatic skin cancer called melanoma. This is (perhaps) very important for prostate cancer patients.

More data to come at ASCO in June

We commented earlier today on the positive data about tasquinimod that will be presented at the ASCO annual meeting. Negative data will unfortunately be presented on other drugs, but not everything is doom and gloom.

Tasquinimod in treatment of patients with metastatic CRPC

Looking quickly through the abstracts of presentations on investigational  therapies to be presented at the annual meeting of the American Society for Clinical Oncology (ASCO), starting on June 4 in Chicago, one particular paper stood out — a Phase II trial of tasquinimod.

Time off therapy after a first cycle of intermittent ADT

A new report has suggested that, for men treated with intermittent androgen deprivation therapy (ADT) after biochemical relapse following surgery or radiation, the length of the first time-period off androgen deprivation therapy (ADT) may correlate with time to onset of castration-resistant prostate cancer (CRPC) and prostate cancer-specific mortality.
