The good news for cancer patients is that novel therapies are extending
lives and even allowing cancer to be treated as a chronic disease.
The bad news is they may not be accessible to everyone.
By the time Kara Herynk was diagnosed with
large cell neuroendocrine carcinoma of the cervix in February 2005,
the cancer had spread to her brain and liver.
Doctors prescribed eight rounds of very high doses of cisplatin
and Vepesid® (etoposide) chemotherapy, a craniotomy to remove
a large brain tumor and a hysterectomy. She also underwent three
rounds of stereotactic radiosurgery to treat six more brain tumors.
And more radiosurgery treated cancer in her lymph nodes, adrenal
gland and lung.
Earlier this year, samples of Herynk’s tumor tissue were analyzed
using microarray, a test that identifies tumor protein patterns.
The test found that Herynk’s tumor is HER2 positive, so doctors
prescribed Herceptin® (trastuzumab), a monoclonal antibody the
Food and Drug Administration approved to treat HER2-positive metastatic
breast cancer. But because the drug isn’t approved to treat
Herynk’s primary cancer type, her health insurance company
refused to pay for the treatment, calling its use “experimental.”
“It was shocking at first, because the insurance company had never denied
anything,” says Herynk, 32. “I was excited about Herceptin because
my bone marrow was so suppressed from all the chemotherapy, it was the only
drug I could take because it wasn’t as toxic.” In April, convinced
that the drug could be beneficial and despite its high monthly price tag of
more than $3,000, the Herynks began paying for the drug themselves, a decision
that put her family in a precarious financial situation.
Herynk’s husband, Matthew Herynk, PhD, a breast cancer researcher
at Baylor College of Medicine in Houston, says coworkers and family
members donated money to help pay for the drug and the couple went
through their savings when finally, after several appeals, their
health insurance carrier agreed to pay for Herceptin. Still, Matthew
says he’s willing to go bankrupt to pay for any drug that
might make a difference in the outcome of his wife’s disease.
“There’s no doubt that Herceptin has been a lifesaving drug for
me,” says Kara. “Since I’ve been on the drug I haven’t
had any new tumors. My cancer is so aggressive, I can’t imagine where
the cancer would have gone if I hadn’t had Herceptin.” Matthew
agrees. “I know enough about cancer biology to believe that this drug
is making a difference, so I’m willing to put everything I have into
whatever drugs I think will make a difference.”
The Herynks aren’t alone. Many cancer patients today are facing
the same dilemma of how to pay for cancer drugs. According to the
2006 Express Scripts Specialty Drug Trend Report, the cost of oral
cancer drugs rose nearly 16 percent in 2005—an average of
$1,600 per prescription. With costs soaring to never-before-seen
heights, especially for the new targeted therapies, which directly
affect cancer cells and don’t have the same toxic effects
of conventional chemotherapies, the yearly bill can reach upwards
of $100,000, and carry insurance copayments of $10,000 or more a
year.
As a result, cancer patients, doctors and health insurance companies
have to consider the cost-versus-health benefit ratio when deciding
on treatment, especially if the drug is only expected to have a
marginal effect on survival. Compounding the problem is that often
the newer targeted drugs have to be combined with conventional chemotherapies
to be most effective, driving up both the cost and the severity
of side effects.
Leonard Saltz, MD, attending physician at Memorial Sloan-Kettering
Cancer Center and professor of medicine at Weill Medical College
of Cornell University in New York City, says he’s disappointed
by what most targeted therapies have been able to accomplish as
single agents. “No one set out to combine these drugs with
chemotherapy. They were supposed to replace chemotherapy and all
of its nasty side effects, but it hasn’t worked out that way.”
Of the targeted therapies, only Gleevec® (imatinib), which has
had remarkable results in the treatment of gastrointestinal stromal
tumors and chronic myeloid leukemia, has shown long-term survival
rates. For example, a clinical trial of Gleevec found that 90 percent
of CML patients who took the drug were still alive five years after
diagnosis. However, the drug has to be taken indefinitely, at a
cost of up to $3,800 a month. “As an individual, the cost
is worth it, but from a societal point of view, economists argue
that it’s a serious problem,” says Dr. Saltz.
Other medical experts argue drugs that offer any incremental rate
in survival constitute a significant advancement in cancer treatment. “It’s
important to note that these new drugs are quite good,” says
David Johnson, MD, deputy director of the Vanderbilt-Ingram Cancer
Center in Nashville and past president of the American Society of
Clinical Oncology. “When people make comments like they only
affect a two-month improvement in median survival, that demonstrates
a lack of understanding of what that means. They’re talking
about an average benefit.”
Dr. Johnson, who is himself a lymphoma survivor, says all the benefit
doesn’t accrue equally to every patient. It might be that
one patient survives four months longer and one patient doesn’t
survive any longer.
Plus, says Dr. Johnson, agents like colon and lung cancer drug Avastin® (bevacizumab)
are tested in clinical trials of patients with late-stage disease
when the chances of survival are small. The same is true of Herceptin,
which affected only a modest benefit in terms of overall survival
for women with metastatic breast cancer, but when Herceptin was
tested in the more favorable setting of treatment after surgery
(adjuvant), it resulted in a 50 percent improvement in disease-free
survival. “We anticipate that will translate into a substantial
benefit in terms of overall survival, so who knows what Avastin
is going to do when we start using it in earlier stages of disease
as opposed to the worst-case scenarios,” says Dr. Johnson.
Financial Aid
Walter Moore, vice president of government affairs for Genentech,
maker of both Avastin and Herceptin, which just received FDA approval
for use as adjuvant treatment for breast cancer in November, says
the company plans to test Avastin as adjuvant treatment for breast
and colon cancer. But the question remains, how will patients—and
society—pay for new drugs? The question applies not only
to cancer, but also to other illnesses like heart disease, which,
according to the Agency for Healthcare Research and Quality, is
the most expensive health condition overall in the United States
(though the per-person cost puts cancer on top, followed by heart
disease).
A voluntary solution puts caps on the price of drugs. It has been
reported that a number of pharmaceutical companies are considering
caps on high-priced cancer drugs, but so far only Amgen and Genentech
have put price caps in place.
Amgen, maker of Vectibix® (panitumumab), a newly approved colon
cancer drug priced at $4,000 per two-week infusion, announced a
cap on out-of-pocket copayments after approval of the drug in late
September. Patients on Vectibix are now able to get the drug for
free once copayment costs exceed 5 percent of their adjusted gross
income, regardless of insurance status or income.
Genentech followed suit in October after the additional approval
of Avastin for non-small cell lung cancer (FDA approval is still
pending on its use for breast cancer). The Avastin program caps
the cost of the drug at $55,000 a year for eligible patients. The
price cap, says Moore, was determined by the escalating price of
Avastin based on treatment dosage. The current treatment for lung
cancer ($8,880 per month) is at double the dose than for colon cancer
($4,400 a month), although clinical trials are still ongoing to
determine whether lower doses of Avastin would be just as effective. “I’m
not sure what will turn out to be the proper clinical dose, but
our objective is for oncologists to choose the regimen that produces
the best clinical outcome without concern for the additional expense,” says
Moore. The Avastin expenditure cap is the first of its kind, putting
a cap on spending by all payers, not just out-of-pocket costs from
the patient. The program will cover all approved uses for Avastin.
Diane Blum heads CancerCare, a nonprofit organization that provides
financial assistance and free services to cancer patients, although
it doesn’t directly pay for drugs. As more cancer drugs have
been approved over the years, she says momentum has developed concerning
the cost issue. “It’s become a critical mass of drugs
that are costing a whole lot of money,” she says. “The
companies get a lot of negative press about it and understandably—the
drugs are very expensive. I think the caps are an attempt to do
the right thing so people aren’t shut out of getting the drug
but at the same time maintain pricing abilities without interference.” Blum
thinks other drug companies will replicate the proactive move of
Amgen and Genentech. “There will be pressure for any company
that has a newly approved drug to take similar action.”
Apart from price caps, most pharmaceutical companies have patient
assistance programs that offer drugs for free to patients who qualify.
Nonprofit organizations and government agencies also help low-income
patients with little or no insurance get access to needed drugs.
Though most middle-income patients who are covered under private
insurance or Medicare are ineligible for many patient assistance
programs and take the hardest financial hit, some assistance programs
offer discounted rates or financial help for patients who are underinsured
or who have extreme financial burden because of their treatments
(see sidebar).
A study in a recent issue of the journal Cancer shows that one in
five cancer patients delay or miss needed care because of cost (see
sidebar, page 50). And, according to 2005 U.S. Census Bureau figures,
the number of Americans without health insurance rose by 1.3 million
to an all-time high of 46.6 million, putting additional financial
strains on an already fragile healthcare system. Blum says she has
seen an increase in the number of calls to CancerCare from people
looking for financial help. “At the end of our fiscal year
in June, we spent about $4.5 million in direct financial assistance,
but it goes primarily to help people pay for things like transportation
to and from treatment appointments. If people can’t get to
treatment, they simply don’t go,” says Blum.
And, as Kara Herynk found, more and more health insurers are refusing
to pay for treatments prescribed off-label. “What we find
are extremely concrete and restrictive interpretations of the FDA
approval guidelines as limiting factors for the drug’s availability,” says
Dr. Saltz. “So rather than figuring out a way to deal with
[the drug cost], insurers are trying to find ways not to pay for
it and, therefore, certain people can’t get it.” For
example, the FDA approved Avastin for colon cancer, which affects
the large intestine, so Dr. Saltz says he can’t prescribe
it for his small intestine cancer patients, because insurance companies
won’t pay for the treatment.
That practice isn’t about
to end anytime soon, says Susan Pisano, vice president of communications
for America’s Health
Insurance Plans, a Washington, D.C.-based organization that represents
health insurance companies. “We’re moving toward a healthcare
system that is based on what the medical evidence shows. The insurance
companies want the nation to move to a system where we’re
using the evidence that shows the new treatments are better than
the existing treatment.”
Physicians admit insurance restrictions
and drug costs are impacting the way they treat patients. “Ten
years ago I gave very little thought to the drugs that I recommended
to the patient, because cost wasn’t really an issue,” says
Dr. Johnson. “Now,
sadly, physicians are doing a financial sizing of each patient.
Do I want to discuss with a patient a therapy I know the patient
won’t be able to receive because of cost, or do I want to
put on patients the added burden of worrying about mortgaging their
home?”
The pharmaceutical companies argue that cancer drugs
are expensive because of the amount of time and money it takes to
bring them to market. “We discovered Avastin in 1989 and it
was approved [for colon cancer] in 2004,” says Genentech’s
Moore. “So
you have 15 years and $800 million to get a drug approved. By any
stretch, it’s a wildly expensive way to get a new therapy
into the hands of doctors and into the bodies of patients.” Very
few compounds make it from laboratory testing to clinical trials
in humans. From there, only one out of every 10 drugs will be approved.
A
drug company attempts to recoup its investment before the drug’s
patent expires 20 years after the application date, because at that
point a generic version of the drug is developed and marketed. At
a cost of 30 to 80 percent less than brand-name drugs, generics
have the same active ingredients and therefore the same effects,
causing an immediate drop in price and market share for brand-name
drugs.
The cost of drug research and development will continue to
rise. In 1991, the cost of developing a drug averaged $168 million,
more than doubled to $365 million in 1997 and jumped to more than
$800 million in 2003. Since it takes an average of 12 to 15 years
to bring a drug to market, by 2015, the cost of developing a drug
would cost an estimated $1.9 billion, according to research published
in the Journal of Health Economics. In 2005, pharmaceutical and
biotechnology companies invested $51.3 billion in research and development,
according to an analysis commissioned by the Pharmaceutical Research
and Manufacturers of America, the drug industry’s trade group.
The
FDA had a hand in founding the Critical Path Institute, or C-Path,
which began operations in mid-2005 to, among other things, simplify
the clinical testing process and thus lower the cost of drug development.
C-Path reached an agreement in 2006 with eight major pharmaceutical
companies, including Bristol-Myers Squibb, Merck, Novartis and Pfizer,
to share early-stage drug testing methods.
Drug companies also say
a drug’s therapeutic value can lead
to a higher price. Thalomid® (thalidomide), a drug that’s
been around for years to treat leprosy, was recently approved to
treat multiple myeloma and costs $3,500 or higher per month. When
65-year-old Dick Wells was diagnosed with multiple myeloma in 2002,
his health insurance company covered the cost of the drug and he
paid a modest $25-per-month copayment.
After he turned 65 and went
on Medicare, Wells purchased supplemental health insurance to ensure
he would be covered for the cost of thalidomide. But when he went
to the pharmacy to pick up his prescription, he was shocked to learn
that his copayment had shot up to nearly $1,900.
“I told the druggist that I couldn’t pay for the prescription and
gave him back the pills, but then I started thinking that I have to have these
pills. I really didn’t have a choice,” says Wells. Although he
missed several days of medication while he researched other supplemental plans,
he finally found one that covered the cost of thalidomide.
Celgene Corporation,
thalidomide’s manufacturer, justifies
the cost because “the therapeutic value of thalidomide is
in line with other cancer breakthrough therapies and it’s
half the cost of existing breakthrough therapies in the multiple
myeloma area,” says Brian Gill, director of public relations
for Celgene. Indeed, the multiple myeloma drug Velcade® (bortezomib)
costs about $6,600 per month, and Celgene’s own recently approved
Revlimid® (lenalidomide) costs up to $8,850 a month.
Because
cancer is such a frightening disease and patients will do anything
to gain access to drugs they believe will help them live, healthcare
shouldn’t be part of a free-market system in which
price is determined by what the market will bear, says Dr. Johnson. “Who’s
the competition and who’s in a position to bargain? There’s
just something not right about this system.”
Is Universal Healthcare the Answer?
John Hornberger, MD, adjunct
clinical professor of medicine at Stanford University School of
Medicine and a practicing physician who studies drug costs, says
drug prices, no matter the illness, are based on a three-legged
stool argument.
“You’ve got to have demand for the drug, and that’s clearly
the case in oncology. You’ve got to have innovation to satisfy the demand,
and the third leg of the stool is who’s going to look at the cost? If
there’s no one looking at cost, people will charge whatever they want
and that’s effectively where our healthcare system has been, but it’s
not sustainable,” he says. Dr. Hornberger cites a growing older population
and the increased cost strains it places on Medicare as some of the reasons
why. “There are no cost brakes on the Medicare system. Congress won’t
let Medicare use cost to decide how care will be provided and people are just
using more drugs,” says Dr. Hornberger.
But with healthcare spending projected
to soar to $4 trillion by 2015, outpacing the growth in the gross
domestic product by 20 percent—up
from 16 percent today—healthcare industry experts and government
agencies are starting to look for ways to control drug costs. In
October, the National Coalition for Cancer Survivorship brought
together representatives from health insurance and pharmaceutical
companies, the FDA, the Centers for Medicare and Medicaid Services,
physicians and patient advocacy groups to study the problem. The
report is pending.
“The drug cost issue has finally come up and hit us square in the face,” says
Ellen Stovall, president and CEO of the NCCS and a 35-year cancer survivor. “It
used to be manageable because either insurance companies paid for the drugs
or the out-of-pocket costs were manageable, but that’s no longer the
case.”
Dr. Johnson predicts that rising medical costs will eventually
lead to a federal government plan that will provide basic healthcare
to everyone. (The United States is the only developed country in
the world without universal healthcare, and many developed countries
regulate drug prices.) “I think this is going to end up being
some sort of crisis, but I suspect that what will ultimately happen
is that the country will grow a social conscience and it will decide
that we have to do something. It’s unconscionable to me that
the wealthiest country in the world has 46 million people without
health insurance.”
