Commentary on Science, Innovation & New Products with a focus on Oncology, Hematology & Cancer Immunotherapy

We hope that everyone had a relaxing holiday break and now it’s time to get back to work.  Tomorrow I will review some more of my thoughts in the immuno-oncology space, since that area had a tremendous amount of progress in San Diego with lots of new ideas to process and summarise.

In the meantime, a few people have written in and asked about what was happening with overcoming resistance in various tumour types, was there anything new to say in that space that was in addition to the the detailed previews we covered before the conference?

Actually, there was a quite a few posters and presentations that caught my eye, so I thought this would be a good idea to review them here:

Lung Cancer: HER2, VEGF, T790M, EGFR, erlotinib, gefitinib, trastuzumab, bevacizumab, CO-1686, AZD9291

Prostate Cancer: mTOR, PI3K, Androgen Receptor, enzalutamide, abiraterone, CC214–2, ARN–509, BET Bromodomian inhibition, ODM–201, GDC–0980, GDC-0068, PF–04691502, BKM120, BEZ235

As 2013 comes to an end, rather than look back as many are doing, I’m looking forward to 2014. January is a busy month for cancer meetings with the ASCO organized gastrointestinal cancers symposium (ASCO GI) and genitourinary cancers symposium (ASCO GU) both taking place in San Francisco a few weeks apart.

In fact, looking at the calendar of forthcomings meetings, 2014 looks to have a West Coast focus, with the annual meeting of the American Association for Cancer Research (AACR) taking place in San Diego in April, and the American Society of Hematology (ASH) annual meeting also heading to San Francisco in December.

Transcontinental airfares are notoriously expensive at the last minute so if flying from the East Coast, do make travel plans early!

The ASCO GU symposium takes place at the San Francisco Marriott Marquis from Jan 20 – February 1, 2014. The abstracts for meeting go online at 5pm Eastern Time on Jan 28.

ASCO in a December 19 press release have already announced what will be highlighted on the January 28 press cast, and what many of the media can be anticipated to write about from the meeting.

Perhaps not surprisingly the Medivation PREVAIL trial data (LBA1) is top of the list; the abstract for this presentation has already been published online as Professor Tombal (@BertrandTOMBAL) kindly highlighted on Twitter.

This preview highlights some of the prostate cancer abstracts and presentations to watch out for at the meeting:

Drugs discussed in this post include: enzalutamide (Xtandi), abiraterone (Zytiga), ODM-201, ARN-509, ipilimumab (Yervoy).

Amsterdam – Earlier today, I had the great pleasure at the European Cancer Congress to interview Oliver Sartor, MD, the Piltz Professor of Cancer Research in the medicine and urology departments of Tulane School of Medicine in New Orleans, LA.

A recognized expert in prostate cancer, Dr Sartor was gracious enough to give me an impromptu interview in the poster hall at ECCO 2013 and share his thoughts about the prostate cancer clinical data presented in Amsterdam.

One of the late-breaking abstracts (not yet published) that I am looking forward to at the forthcoming annual Congress of the European Society for Medical Oncology (ESMO 2012) in Vienna is on ODM-201 (Orion Pharma):

LBA25-PR:  ARADES trial: A first-in-man, open-label, phase I/II safety, pharmacokinetic, and proof-of-concept study of ODM-201 in patients (pts) with progressive metastatic castration-resistant prostate cancer (mCRPC)

ODM-201 is a new antiandrogen from Finnish company, Orion Pharma, and is being developed in partnership with Endo Pharmaceuticals (NASDAQ: ENDP).

Orion Pharma LogoIn a corporate presentation, Orion Pharma describe ODM-201 as:

  • Potentially best-in-class antiandrogen
  • Does not enter brain in preclinical models
  • No testosterone increase in animal models
  • Well tolerated

“We are studying and developing an anti-androgen with qualities that currently cannot be found in any of our or our competitors’ drugs”

says Mika Mustonen (@MikaMustonen), Head of Oncology, Research and Development at Orion in an article, “Pursuing a targeted drug for prostate cancer” published by the company. Mustonen says:

“The research on our new drug candidate, ODM-201, suggests that we may be able to provide patients with a new alternative for the treatment of prostate cancer.”

Of note, is Orion’s focus on biomarkers, which may help predict which patients are more likely to respond to the therapy. According to Mustonen:

“Biomarkers increase the chance of success.  By following them we can study topics that have not been considered before in this type of research.  We can predict different phases of the disease, survey any safety risks associated with the drug and find out what kind of patients benefit most from the drug.”

At ESMO 2012 (Twitter hashtag #ESMO12) I expect we will hear preliminary data from the ARADES 3104001 phase 1 dose escalation study (NCT01317641) with ODM-201.

According to clinicaltrials.gov this multicenter, non-randomized clinical trial is being undertaken at sites in Finland, Czech Republic, France, United Kingdom and the United States.

After 12 weeks in the phase 1 dose escalation study, patients with stable disease can continue treatment in a phase 2 extension study on the safety and tolerability of ODM-201 (NCT01429064).

As of May 2012, Orion Pharma reported that the ARADES 3104001 phase II expansion component had 105 patients enrolled, with 3 dose levels to be expanded.

Company senior management have told me they “are very excited about the ODM-201 data,” to be presented at ESMO. I have not seen the data, but presume the results will be positive. After all, company executives don’t get excited about negative data!

Is there a market for a new antiandrogen?

Although Medivation are first to market with their androgen receptor (AR) inhibitor, enzalutamide/MDV3100 (Xtandi) that does not mean that other companies will not be able to make in-roads into the market with cheaper or more effective AR antagonists.

In a Pharma Strategy Blog interview with Sally Church, Dr Charles Sawyers noted that Aragon’s ARN-509 (another AR inhibitor in development) is “more potent” than enzalutamide and “might produce a higher percentage of responders or longer duration of response.”

Medivation recently announced that enzalatumide is available in the United States for patients with metastatic castration resistant prostate cancer previously treated with docetaxel.

At a price of $7,450 a month, however, Xtandi is considerably higher than Johnson & Johnson’s Zytiga.  This aggressive premium pricing strategy opens the door to competitors who may offer equally effective, but less expensive drugs.

The prostate cancer market remains a dynamic one and very much one to watch over the next few years.

I look forward to learning more about ODM-201 at ESMO 2012.
