I hope no one minds me taking a short victory lap over my story this week about the American Society of Clinical Oncology's
decision (finally!) to post online its annual meeting research abstracts, making them accessible to everyone.
No more selective disclosure. No more ASCO data leaks.
I started writing about the inequities of ASCO's abstract disclosure policy six years ago. My media credentials for the 2001 ASCO annual meeting were yanked because of those first stories, but I kept at it. (You can read some vintage Feuerstein
I've been a pit bull on this story ever since, so it was more than a bit gratifying to see ASCO change course. A lot of credit goes to ASCO leadership for finally getting it right, but if you don't mind, I'll pat myself on the back, too. Just a bit.
Here's an update on
, but first a reminder on my company thesis: It has lots of cancer drugs in the pipeline, all going after "sexy" anticancer molecular targets. It also has a partnership with
. I'd expect some clinical failures and setbacks, which can be seen as potential buying opportunities. Exelixis needs only one or two pipeline drugs to hit for the stock to work.
Now, the update: Phase II data on Exelixis' XL880 in papillary renal cell cancer patients was OK, not spectacular. Of 19 evaluable patients, there was one with a partial response, 14 others with stable disease, although some of those tumor-growth stoppages were quite long.
My sense is that the Street wanted more than a 5% response rate. It's worth noting that Nexavar (made by
) was approved for renal cell cancer with a low-single-digit response rate. The efficacy came from a high percentage of patients with stable disease, which, in turn, boosted progression-free survival. Could XL880 fit this mold?
Exelixis sold off a bit after the data were released Oct. 24, and it's traded basically flat since then. Glaxo has an option to take control of XL880, with a decision expected in mid-December.
The American Association for the Study of Liver Disease is holding its annual meeting in Boston this weekend and into next week. I'll be there, reporting all the latest data and buzz on hepatitis C drugs. The media embargo for the meeting lifts Friday morning, so expect to see a bunch of press releases at that time, including one from
on the SVR, or cure, rate for telaprevir in the phase II study known as Prove 1.
Here are some other questions I hope to address over the weekend:
- How competitive is
Schering-Plough's (SGP) protease inhibitor boceprevir?
InterMune (ITMN) and its protease inhibitor ITMN-191 still relevant?
What other companies are out there working to develop a protease inhibitor?
Johnson & Johnson (JNJ) - Get Report?
Can any of the polymerase inhibitors for hepatitis C, including those from
Pharmasset (VRUS) , compete on efficacy?
Viropharma (VPHM) polymerase inhibitor, recently knocked down for toxicity, dead or can it mount a comeback?
Gilead Sciences (GILD) - Get Report have cooking for hepatitis C?
An update on
Let's focus on bapineuzumab, the Alzheimer's disease drug candidate that Elan is co-developing with
. A phase III program for "Bap" is on track for a year-end start, and it's a biggie: 4,000 mild-to-moderate Alzheimer's patients will be enrolled across four international placebo-controlled studies. Patients in the trials will be treated for 18 months, so data are a long way off.
In the meantime, the highly anticipated presentation of Bap data from a phase II study will take place in mid-2008. The fact that regulators in the U.S. and Europe have seen some of this data already before allowing the phase III program to start assumes that it's not half bad.
But as we've seen with other Alzheimer's programs (i.e.
), shaky phase II data isn't something that stops companies from running phase III trials.
We'll see what the phase II Bap data looks like soon enough. Meanwhile, I expect the start of the phase III trials will be enough to keep investors excited.
The Notebook will not be a forum to respond to reader email (for that, we have the weekend Biotech Mailbag), but I did want to pass along a couple of links to the folks who think I unfairly slammed

I'm curious: Where is that ipilimumab data from the phase III melanoma study that
promised us? One happy group has been short-sellers, who've made money without needing to see bad data. The stock has been a laggard, dropping to around $12 this week. In August, it traded at $18.
I had given up
for dead because of GlaxoSmithKline's lousy launch of the heart disease drug Coreg CR. But behold: Coreg CR sales of $62 in the third quarter (up from $20 million in second-quarter sales) were a pleasant surprise.
That report, plus some early data on a hepatitis C drug in Flamel's pipeline, has helped pop Flamel shares from $8 to above $11. Flamel lives! A strong fourth quarter for Coreg CR will really come in handy.

FDA decision date for indiplon is Dec. 12.

Normally, I'd be skeptical about such gimmicky maneuvers, but RXi does have an ace in the hole -- the company's research platform is based on work done by Dr. Craig Mello. He won the Nobel Prize for Medicine last year for his work on RNAi, which involves gene manipulation Mello is on RXi's scientific advisory board and an investor in the company.
