If It’s June, It Must Be Time To Talk
About Cancer Care Every year, when
oncologists
gather at the annual American Society of Clinical Oncology (ASCO) conference, there is a flurry of
press releases detailing the results of new clinical studies, with
scientists and researchers presenting their findings to physicians looking
for new treatments and answers at the ASCO sessions. With the buzz that is
generated, one would think that we are on the verge of finding a "cure"
for cancer.
At last year’s
conference, the big winner was Genentech’s (NYSE: DNA) drug Avastin
for the treatment of colorectal cancer. After failing in clinical trials
for breast cancer, no one expected much from the colorectal cancer trials
for Avastin. But they were wrong in a big way, as investors watched DNA’s
shares almost double in value on news of the trial results. Now, just a
year later, people are referring to the new cancer-fighting drugs as the
"children of Avastin," based on similar principles but with more bells and
whistles, and there were plenty of new developments. Erbitux, made by
Imclone Systems (NASDAQ: IMCL), was also one of the big winners at
last year’s conference, but unlike Avastin, that was expected.
As an aside, as the ASCO
conference was coming to an end, an estimated 18,000 biotech scientists,
executives and government officials were in San Francisco for the annual
Biotechnology Industry Organization conference. Protesting genetically
modified food, more than 200 demonstrators turned out, 25 of whom tried to
block access to the convention center and were arrested for their efforts.
It is reminiscent of the days when an organization known as ADAPT used to
crash the annual nursing home association conference, scream profanities
at the attendees and try to flood one of the hotels. Those were the days.
A year ago, in addition
to DNA and IMCL, several smaller biotech companies were able to piggyback
on the market success of Avastin and Erbitux and watched as their shares
doubled and tripled in value because they were developing similar drugs
and investors were hedging their bets with the assumption that some of
these could be break-out drug candidates. This year, despite what seemed
to be an abundance of good news on the cancer front, investors found
little to be impressed about during the conference, and after the initial
run-up in prices in anticipation of the ASCO conference, there was a
post-conference slip in values as investors became disappointed that no
blockbuster developments were announced.
For two years running,
however, Imclone Systems was the star at ASCO, as recent trials for
Erbitux to treat head and neck cancer were successful, sending IMCL’s
shares up above $80 per share and near their all-time high. Although few
people are shedding any tears for Martha and Sam these days, those two may
be getting a little teary thinking about what could have been (or not).
All it took was a little faith.
Someone likened the
progress in cancer treatment as evolving from the dirty bomb
(chemotherapy), to the smart bomb (Avastin) and now the cluster bomb that
has multiple targets. The problem with the cluster bomb is that as a drug
hits more targets, the higher the likelihood of side-effects and toxicity.
This may be true in some cases, but the side-effects of chemotherapy are
about as bad as it gets, so patients will presumably tolerate anything
that the cluster bombs throw at them.
According to a monthly
tracking survey of 27 oncologists done by the health care group at SG
Cowen, both Avastin and Erbitux are seeing increased use by the
physicians monitored. This group, which includes academic and community
oncologists, treats a combined 2,473 stage IV (metastatic) colorectal
cancer patients. In the May survey, physicians indicated using Avastin in
43% of their first-line patients, compared with just 23% in April, and in
3% of their third-line patients (2% in April). Erbitux, on the other hand,
was used with 20% of their second-line patients in May (12% in April) and
27% of their third-line patients (23% in April). This increased use caused
the analysts at SG Cowen to increase their 2004 U.S. sales forecast for
Avastin and Erbitux by 24% and 26%, respectively. The 2005 forecasts were
increased as well, but not quite as dramatically.
In another statistic that
bodes well for the two drugs, 26% of the oncologists in the survey group
have used Avastin for conditions other than colorectal cancer (22% for
Erbitux), and they expect that to increase to 63% and 56%, respectively,
in six months. These are just some of the reasons why IMCL has more than
doubled in value in the past year and DNA has jumped by more than 50%. The
SG Cowen report (dated June 3) goes into much more detail and is well
worth the time for any interested investors.
Getting back to the ASCO
conference, several companies reported positive results from clinical
trials dealing with everything from breast cancer (Gemzar) to prostate
cancer (Atrasentan), non-Hodgkin’s lymphoma (Rituxan), multiple myeloma (Velcade)
and kidney and stomach tumors (SU11248), the last one being developed by
Pfizer (NYSE: PFE). One company was particularly prolific in the
press release department, with the results of three Phase II trials
disclosed by Telik (NASDAQ: TELK) in one day. In a trial with 21
patients with ovarian cancer who had previously failed to benefit from
standard treatments, 56% of the patients who took TELK’s experimental drug
Telcyta in combination with carboplatin (platinum-based chemotherapy) saw
their tumors shrink by 50% or more, with three of the patients having no
sign of cancer remaining. Apparently, when used alone, carboplatin usually
produces tumor shrinkage in just 10% of patients with advanced ovarian
cancer.
In a separate trial also
involving 21 patients with ovarian cancer, Telcyta used in combination
with liposomal doxorubicin, a drug usually used when several rounds of
chemotherapy have failed, 46% had a significant shrinkage in their tumors,
compared with 13% that is typical when Doxil is used alone. In the last
Phase II trial, this for patients with non-small cell lung cancer (NSCLC),
Telcyta combined with docetaxel had a 27% objective response rate with one
complete response.
Telcyta is in Phase III
trials for NSCLC and ovarian cancer, and has also tested positively in
Phase II trials for breast, ovarian and colorectal cancer. This small
molecule drug is activated by GST P1-1, an enzyme present in cancer cells.
Upon activation, an intracellular process known as apoptosis, or
programmed cell death, occurs. Although the Palo Alto, California-based
company has no meaningful revenues, continued success with Telcyta will
change that. TELK’s shares are up 50% from a year ago, but considerably
below the 52-week high set in April.
Whether a case of jumping on the
bandwagon or looking for a way out of its rut, Schering-Plough
(NYSE: SGP) wants to be a bigger player in the cancer market. Only 10% of
the company’s revenues come from drugs that treat various forms of cancer,
including $324 million from Temodar, a drug to treat brain tumors. At the
ASCO conference, SGP presented results from a trial involving 573 patients
with glioblastoma multiforme, a form of brain cancer which usually is
fatal within a year. Two years after treatment with Temodar and radiation,
27% were still alive, compared with just 10% receiving radiation alone. In
addition, tumors did not recur after two years for 11% of the patients in
the trial, compared with 2% getting just radiation. SGP would like to buy
one or more small companies with promising cancer treatments in
development. Would Telik, which has a market cap just under $1.0 billion,
be too large?
