Provenge, why so expensive? Yes there are development costs and clincal trials to pay for but not enough, in my view, to justify the pricing. We talk about holding practitioner’s fees down by looking at outcomes, shouldn’t we do the same with drugs that cost 100 times more?

The FDA by the way is not allowed to assess cost efficacy, their mandate is to document lack of harm and have evidence of minimal benefit. Interestingly, many times in the past the initial studies benefit was proven to be overstated and the risks understated.

The treatment’s benefits are modest. But as the first product of its type to emerge from decades of often-frustrating research, Provenge could help open doors for immune-based therapies against a range of cancer.

Analysts estimate a course of Provenge will cost between $50,000 and $75,000. As many as 100,000 men a year develop the advanced form of prostate cancer the treatment would initially be prescribed for. At that rate, Dendreon could rack up well over $1 billion in annual sales in a few years, said David Miller, president of Biotech Stock Research in Seattle. If the company isn’t swallowed up by a pharmaceutical firm — a big “if” — its success would boost the region’s stature and draw as a biotech hub.

The vaccine boosted median survival time by 4 months, from 22 months in the placebo group to 26 months in the Provenge group.

Medicynical note: The company claims an investment of $750,000,000–it’s been thought by many that these “investments” are routinely overstated (Read Marcia Angell and her book The Truth About the Drug Companies: How they Deceive Us and What to Do about it). Dendreon’s estimate is that the drug in the first year will provide over a billion dollars in sales. Don’t expect the prices to go down with time.

It is the American way to reward innovation and this approach clearly is innovative, though modestly effective. But can any system afford such pricing for an incremental (3-4 month), if that, improvement? Isn’t there a more efficient way to drug development? If health insurance wasn’t there to buffer patients and their families could the majority of us afford such an “advance.” Can we as a failing society, slowly bankrupting ourselves, afford it?

Non-resectable metastatic non small cell lung cancer is a uniformly fatal illness. Patients may respond temporarily to treatment but in virtually all cases the disease will eventually progress. Therapy, depending on the extent of disease, is a combination of chemotherapy and radiation.

Erlotinib (Tarceva), a epidermal growth receptor inhibitor (HER1/EGFR), was recently approved by the FDA as maintenance therapy for the disease in patients with stable disease after treatment with platinum based therapy. The approval was based on the results of the Saturn study which was reported at the 2009 ASCO meeting.

The study showed:

Response rate was 12% with E versus 5% with P (platinum based treatment). Disease control rate (complete response + partial response + stable disease >12 wks) was
40.8% with E versus 27.4% with P (p<.0001). OS (Overall survival) data are not yet
mature.

Further analysis released in August 2009 showed:

The study showed that patients with NSCLC treated with Tarceva had a 23 percent improvement in overall survival compared with patients who received placebo (hazard ratio=0.81; p-value=0.0088). The hazard ratio, which assesses risk in the overall trial population, is widely recognized as the best measure of overall benefit in large randomized clinical trials. A hazard ratio of less than one for survival indicates a reduced risk of death. The median survival (a single point estimate of benefit) for patients receiving Tarceva was 12 months versus a median survival of 11 months for patients receiving placebo. (medicynical emphasis)

Medicynical note: The yearly cost of Tarceva is in the range of $30,000-60,000/year. This according to the Saturn study buys an improvement in median survival of 1 month. Added to this are the cost of the initial platinum based chemotherapy, radiation if given, doctor’s fees and imaging costs.

Is it cost effective to spend over $30,000-60,000 or more depending on length of treatment for a median survival improvement of 1 month? If not covered by insurance would you pay for this drug? Would you expect someone else to pay for it for you?

Our non-system of care’s great virtue, we’re told, is that the profit motive encourages development of new approaches. The problem is that the profit and costs in our cost plus system of reimbursement are so great that the system and individuals can’t afford the new “advances”–which by the way are mostly of marginal benefit.

For the past thirty years in oncology we’ve been combining therapies to improve outcomes. When each of the drugs in combination cost under $1000/month, such combinations were doable. While expensive for the time, their cost does not compare with the current situation of drugs costing $10,000/month and more.

One example of what’s happening is in the treatment of glioblastom multiforme, the most malignant tumor of the brain, the disease from which Teddy Kennedy succumbed. Standard treatment used to be radiation with or without chemotherapy. Until recently the chemo was older agents that were moderately priced. With the advent of Temodar a few years ago costs have spiraled.

He will need to take 140 mg of temozolomide (75 mg/m2 per day) for 42 consecutive days. Each 140-mg capsule of temozolomide costs $283.32 ($1416.59 for 5 capsules) and the total for 42 capsules is $11,899.44. For the first cycle of metronomic temozolomide (5 days at 150 mg/m2 per day), the patient will need to take 2 of the 140-mg capsules daily for a total cost of $2833.20. For subsequent cycles of metronomic temozolomide (200 mg/m2 per day), the patient will need to take one 250-mg capsule, one 100-mg capsule, and one 20-mg capsule each day for 5 days. The prices for 5 each of the 250-mg, 100-mg, and 20-mg capsules, respectively, are $2334.29, $933.70, and $186.71. The total cost for each 5-day cycle of metronomic temozolomide at 200 mg/m2per day is therefore $3454.70.

If the same patient experiences GBM recurrence, his chemotherapy may be changed to bevacizumab and irinotecan. He will need 10 mg/kg of bevacizumab every 2 weeks. At 155 pounds, he is roughly 70 kg, so he will need 700 mg of bevacizumab. The cost of bevacizumab is $687.50 per 100 mg, so the cost of each infusion will be $4812.50.

Medicynical Note: Remember, each of these costs is for the drug alone. Additional expenses include physician’s fees, imaging costs (MRI’s, etc), other medications and nursing support.

Temozolomide has limited benefits:

Median survival in the radiation-plus-temozolomide group was 14.6 months, compared with 12.1 months in the radiation-only group. After two years, 26.5 percent of patients in the radiation-plus-temozolomide group were alive, compared with 10.4 percent of those who received radiation only. After 5 years, 9.8 percent of patients in the radiation-plus-temozolomide group and 1.9 percent of those in the radiation-only group were still alive.

And in Lancet 2009:

278 (97%) of 286 patients in the radiotherapy alone group and 254 (89%) of 287 (Medicynical note: patients who died over 5 years)

Regarding bevacizumab in glioblastoma, its use is based on small non randomized studies:

One of the trials (known as AVF3708g, or BRAIN) involved 167 patients with glioblastoma who had progressed on radiation and temozolomide (Temodar, Schering) and who then received bevacizumab either alone or in combination with irinotecan. According to an FDA analysis of the study, tumor responses were observed in 22 of 85 patients (26%) treated with bevacizumab alone, and the median duration of response was 4.2 months. (note: that’s a response in just 22 patients. The others were treated, 63 patients and had no benefit whatever)

In another trial (NCI 06-C-0064E), 56 patients with recurrent glioblastoma were treated with bevacizumab alone. Responses were observed in 11 patients (20%), and the median duration of response was 3.9 months. (Note: that’s a response of 3.9 months in the 11 patients who responded. None of the 45 other patients benefited)

There are no data so far from randomized trials for overall survival.

Medicynical Note: The question is can any system afford drugs costing tens of thousands of dollars/month? Can it afford such drugs in non curative situations? Can it afford using two such drugs simultaneously or in sequence if they provide temporary benefit for just a few of the patients treated?

Should we revisit how we develop new drugs? Revise patent law to encourage efficiency and affordability? Factor in cost efficiency when approving drugs? Consider whether our current system of granting generation long monopolies on new drugs is in the best interest of patients? Or the system?

It’s amazing but we have developed a system of drug development that is unaffordable, inefficient, and doomed.

We pay more for care than anywhere else in the world.

Our doctors are among the highest paid in the world

Our medical care, administrative, drugs and medical technology costs are also the highest in the world. This from economix:

One thing Americans do buy with this extra spending is an administrative overhead load that is huge by international standards. The McKinsey Global Institute estimated that excess spending on “health administration and insurance” accounted for as much as 21 percent of the estimated total excess spending ($477 billion in 2003). Brought forward, that 21 percent of excess spending on administration would amount to about $120 billion in 2006 and about $150 billion in 2008. It would have been more than enough to finance universal health insurance this year.

The study used a measure of administrative costs that includes not only the insurer’s costs, but also the costs borne by employers, health-care providers and governments – but not the value of the time patients spent claiming reimbursement. These authors estimated that in 1999, Americans spent $1,059 per capita on administration compared with only $307 in purchasing power parity dollars (PPP $) spent in Canada.

These expenses have to do with expectations:

• Patients expect care: Price should not be an issue, at least to them. These expenses have been buffered by private insurance, government programs, and to a lesser degree our altruism (mandatory access to ER care in emergencies).
• Health care providers also have expectations: They went to great expense and time to go through training and many have huge debts to repay. Their expectation is that they earn an excellent living.
• Medical Insurers expect that they will keep 20% of premiums for their services–contributing to the highest administrative expenses in the world–and million dollar salaries and benefits for their executives
• Medical suppliers, pharmaceutical companies: Huge international corporations also have high profit expectations. Patent laws provide exclusivity for a generation. Drugs are priced not by their cost of development or manufacture but whatever the market will bear. So those with serious illness pay more–because they have to.
• Cost Efficiency is an oxymoron in our non-system: When you have a life-threatening illness cost, efficiency and “shopping” for the best deal are not priorities. Unfortunately, efficacy gets lost in the mix and patients and their insurers, (honoring the patient’s desires) pay exorbitant premiums for treatments that often offer very limited benefit.

Medicynical Note: Expectations and money:

It would seem a given in this the wealthiest (I think that still is the case) economy in the world that health care should be accessible and affordable to all. That is certainly the case in other industrialized nations.

Industry has figured out that health care is not cost sensitive. Why be efficient when the system will pay whatever is demanded. Patients are in a bind and buffered by third party payers; doctors earn more by doing more; industry charges cost plus at every level. Our health care system has become the moral equivalent of the Air Force’s $600 toilet multiplied 100 fold. We now spend more for a single drug than the average and median income–amazing.

One would think that with all this spending everyone would have some coverage, but it’s a fact that we have 50 million uninsured and still spend more per capita by a wide margin than anywhere else in the world.
