Today at the European Association of Urology (EAU) annual meeting in Vienna, the big news was that 2010 was a “Grand Cru” year for new treatments for advanced prostate cancer.  Not only that, but sanofi-aventis announced that they had received European marketing approval for cabazitaxel (Jevtana®) in metastatic hormone resistance prostate cancer mHRPC.

The fact that there are now several new treatments available (or expected to be available in the not too distant future) is good news for patients and physicians.

What is interesting about prostate cancer is that it in terms of incidence it is comparable to breast cancer, yet seems to end up with far fewer resources and publicity.  Prostate cancer is to men, what breast cancer is to women.

The EAU 2011 Congress website has a variety of podcasts and webcasts of presentations, and I encourage anyone interested in the latest developments to check out the wealth of information they offer.  In particular, the presentation by Professor Johann De Bono from the Royal Marsden in the high risk prostate cancer plenary session today was one of my highlights of the meeting.

The take home message I obtained from EAU in Vienna is the excitement of new treatment options for castration resistant prostate cancer (CRPC) such as cabazitaxel, sipuleucel-T and abiraterone.  The challenge may well be to work out how best to use these new therapies, ie in what sequence and what potential combinations may evolve in the future.

However, as Professor Bertrand Tombal from Louvain in Belgium declared, 2010 was a Grand Cru for new prostate cancer treatments.  That is good news indeed.

The news, reported by Bloomberg, last week that generic companies may be subject to stricter FDA standards in order to show therapeutic equivalence is good news for the biotech industry and consumers.

Generic companies have a pretty easy ride in obtaining product approval, and I’ve long been convinced that the formulation of a brand, and what makes it work can include the so called inactive ingredients and how it is put together.   I know of many people who have experienced side effects with generics that they don’t have with the branded product.

For this reason, branded generics from the original manufacturer have the ability to retain some market share in the face of generic competition.  Sandoz, the generic arm of Novartis uses this strategy to good effect with many mature products.   However, if companies instead want to try and maintain a premium priced brand and not adapt to the entry of generics, then they will find their market share erodes extremely fast. Not only is brand market erosion fast with generic drugs, but with biosimilars too.

As reported by Reuters, sales of generic enoxaparin sodium injection, Momenta’s copy of Sanofi’s anti-thrombotic, low molecular weight, heparin sold as “Lovenox” were $292million in the third quarter of 2010. Sandoz markets enoxaparin on behalf of Momenta. They launched the product on July 23, and achieved  $292 million of sales in 69 days. With annual sales forecast to be over $1billion, the biosimilar will be a blockbuster and make a significant dent in the $2.9 billion sales of Lovenox in 2009.

The Boston Business Journal reports that Sandoz/Momenta have captured 60% market share already, which is not good news for Sanofi-Aventis and may explain their desire to make acquisitions such as Genzyme to make up for this loss.

Biosimilars that are fully substitutable for the original product, look likely to erode brands extremely fast.  Momenta’s success is good for the biotechnology industry and highlights the future market opportunity from development of biosimilars.
