MS Drug Prize of $1.3 Billion Spurs Merck KGaA, Novartis Race
By Naomi Kresge
Feb. 13 (Bloomberg) -- Merck KGaA and Novartis AG are racing
to market the first multiple sclerosis pill, a prize that may
generate $1.3 billion a year in sales as patients switch from
injectable drugs.
Merck and Novartis plan to ask regulators this year to
approve tablets to fight the incurable illness. Initial test data
showed that patients who took the drugs had fewer disease flare-
ups than those who received placebo or existing treatments.
A pill may mean an end to painful injections or infusions
that can cost $28,000 a year to control multiple sclerosis, which
can rob people of their mobility and leave them with chronic
aches and depression. Merck, of Darmstadt, Germany, and Novartis,
of Basel, Switzerland, are running ahead of Teva Pharmaceutical
Industries Ltd., Biogen Idec Inc. and Sanofi-Aventis SA in the
chase for an oral treatment. The results may shake up the $6
billion multiple sclerosis market.
“It’s going to be a neck-and-neck race between Merck and
Novartis,” said Markus Mayer, a Munich-based analyst for
UniCredit SpA, after Merck released initial data last month.
The Teva, Biogen and Sanofi pills may not reach patients
before 2012, according to Jack Scannell, an analyst for Sanford
C. Bernstein Ltd. in London. Frost & Sullivan, a research company
based in New York, predicts the market for drugs to treat early
stages of multiple sclerosis may double by 2013.
Merck fell 73 cents, or 1.1 percent, to 67.37 euros in
Frankfurt trading, while Novartis shares climbed 42 centimes, or
1 percent, to 42.51 francs in Zurich.
Cancer Cases
Merck said in January that four patients were diagnosed with
cancer during the late-stage trial of its medicine, known as
cladribine. An independent monitoring board didn’t consider the
cases a safety concern because there were too few to show a
statistical significance, said Phyllis Carter, a Merck
spokeswoman.
Conceived as both a leukemia and multiple sclerosis drug,
cladribine was approved to treat the blood cancer more than 10
years ago and has been used by doctors in injected form to treat
multiple sclerosis in so-called off-label use.
Novartis has also reported two fatal infections and seven
successfully treated cases of skin cancer in patients who took
its candidate, FTY720. Final test results later in the year will
demonstrate how safe each of the medicines is.
If the tablets aren’t linked to such side effects, either
could “revolutionize treatment,” Citigroup analyst Mark Dainty
wrote in a note to clients in January. The products may generate
a total $2.6 billion in revenue in four years’ time, according to
the analyst.
Vulnerable
patient three times a week, had revenue of 1.22 billion euros
($1.57 billion) in 2007. Rebif loses patent protection in 2012,
leaving the German drugmaker vulnerable to generic competition.
Merck reports fourth-quarter results on Feb. 18. Rebif vies with two other so-called beta interferons, Betaseron by Bayer AG and Biogen’s Avonex, and with a fourth injected therapy, Copaxone from Sanofi and Teva. Interferons generally cut patients’ rate of flare-ups by about 25 to 30 percent, Scannell of Bernstein said. To take over the market, the oral medicines first need to overcome safety concerns.
“Concerns over cancer and opportunistic infection are the
real barriers to what could be substantial first-line use in a
multiple sclerosis market worth around $10 billion a year,”
Scannell said in a note to clients this week.
Infection Risk
natural proteins that suppress the entire immune system --
cladribine and FTY720 affect only certain types of cells, said
Doug Brown, research manager for the Multiple Sclerosis Society
in London who doesn’t have financial ties to either Merck or
Novartis. The pills work by lowering the amount of immune cells in the body, leaving patients susceptible to infections, Brown said.
Long-term side effects from cladribine are unproven because
leukemia patients took the drug on a shorter-term basis than
multiple sclerosis sufferers would do, he said.
Emma Delahay, 30, a multiple sclerosis patient from
Canterbury, England, who started taking injected Rebif about two
and a half years ago and has since switched to Copaxone, said she
suffered side effects, including skin rashes, while she was
adjusting to the shots.
A pill would end the disruptive after-dinner routine of
organizing syringes, preparing her shots and choosing a new place
to inject herself every day, she said.
Merck’s study results suggest cladribine and FTY720 could be
as effective as Tysabri, the newest injected multiple sclerosis
drug from Irish drugmaker Elan Corp. and Cambridge,
Massachusetts-based Biogen Idec Inc., according to Scannell.
Risk-Benefit
“Doctors and neurologists will be weighing it up as well.”
In tests, cladribine reduced the relapse rate for the disease by more than half compared with patients given a dummy pill in a two-year study, Merck said last month.The pills, like the injected therapies, work against so-
called relapsing-remitting multiple sclerosis, the most common
form among the estimated 2.5 million people with the disease,
according to the U.S. National Multiple Sclerosis Society.
Symptoms such as loss of vision and numbness flare up and then
subside, and the likelihood of full recovery can sink with each
attack. There is no treatment for rarer forms of the disease in
which patients experience a steady decline.
Merck, which isn’t affiliated with U.S. drugmaker Merck &
Co., said last fall cladribine could be its next $1 billion-a-
year seller.
The Novartis pill may surpass $1 billion in annual sales,
Chief Executive Officer Daniel Vasella said on a conference call
with analysts on Jan. 28.
