Entering La La Land— Cancer Drug Costs Abirateron (Zytiga) vs Sipuleucel-T (Dendreon)

The recent approval of abirateron by the FDA for use in metastatic prostate cancer highlights the otherworldly practice of cancer drug pricing. 

Sipuleucel-T purported to be an immune stimulator in early trials was reported last year to improve survival of patients with metastatic prostate cancer about 4 months  (median) when compared with placebo.  Similarly the recently approved abirateron shows a 2 months delay in progression, 3.9 months improvement of median survival.

Sipuleucel-T (Dendreon) you will recall is priced at $97,000 for a course of therapy.  The new drug abirateron is a relative “bargain” at $5,000/month.

The industry’s view is that this is a “fair” price.  Meaning it is competitive and will earn the company money:

The pharmacy strategy blog notes:

  This gives a treatment price of ~ $40K, which I think is very fair, although some patients will obviously take it for longer than that.

In U.K. however NICE (National Institute for Health and Clinical Excellence) notes:

In draft guidance the watchdog said that Zytiga could increase survival by more than three months compared to placebo, but its annual cost of £35,160 was too much for the NHS in England.

Janssen has offered a patient access scheme for the drug that would discount its list price, but NICE said even with this in place, the drug was still not cost effective.

NICE suggests that conventional chemotherapy offers a more cost effective approach.

Medicynical Note:  Welcome to the alternative universe of drug pricing in the U.S.  This is the only situation where a consumer purchases a product costing many many thousands of dollars that has utility (effectiveness) of 4 months or less.  It’s like buying a Mercedes or Porsche that will last 4 months—rational people in rational situations wouldn’t buy such a product. 

Cancer patients however are desperate.  Drug companies price these drugs to take advantage.  Patient care?  Cost efficiency? Morality?  Not their department. 

I do look forward to further studies of these new agents and hope that the results are confirmed.  However, I would warn readers that the track record of drug sponsored first studies is that they often exaggerate benefits and minimize toxicity. 

Alzheimers: Bexarotene 1200/day (Please note retraction)

I’m a bit embarrassed.  While checking on comments which were critical of this post I inadvertently deleted the original.  It was not  intended  and I am chagrined that it vaporized into the ether.

In any case the questions raised by commenters on the $1200/day pricing for the drug that I posted, appear valid.   The drug may well  cost substantially less.

My source for that pricing was from an ABC news story  which quoted an “expert:”

“The drug will cost between $1,200 and $2,500 per day out of pocket,” said Dr. Sam Gandy, director of the Mount Sinai Center for Cognitive Health in New York. Gandy said families who said they have “nothing to lose” could risk money and “unexpected side effects of a dangerous treatment, and loss of the loved one rather than the gradual deterioration from the disease.”

As noted in the original post, there is no data that indicates this drug is effective at all in humans or that the Alzheimers model in rats behaves similarly to the disease found in humans.

That said I certainly would hope for a response to treatment.

Accountable Care Organization/Global Payments Hand in Glove–Explanation

Nice clear explanation of accountable care and global payments:

  It is widely acknowledged that continued growth in health care spending is threatening the viability of the U.S. health care system. Although there are no clear comprehensive solutions to this problem, most observers see payment reform as the next best hope for reining in out-of-control costs. Our current fee-for-service payment system provides incentives to physicians to increase the delivery of services, which results in excessive utilization. Moreover, neither individual physicians nor the patients receiving the services bear the brunt of these utilization decisions. Rather, they’re reflected in ever-rising health insurance premiums or tax-financed government expenditures shared by all. Many observers are therefore calling for fundamental redesign of the ways in which physicians and hospitals are compensated for the care they provide. Most options call for bundling payments to physicians; specific approaches range from prospective payments for discrete episodes of care (e.g., coronary-artery bypass surgery) to global payment or risk-based models of care.

And:

Conceptually, global payment represents an important opportunity for changing the perverse incentives inherent in our current fee-for-service system. To be successful, however, ACOs must pass these incentives along to their member physicians, who continue to be responsible for most utilization decisions. Although organizations can implement various managerial strategies to influence physicians’ decision making (e.g., radiology decision support and prior authorization), ACOs are unlikely to reduce the rate of increase in health care spending without some essential changes in the behavior of member physicians — and therein lies the rub. The fundamental questions become how ACOs will choose to divide their global budgets and how their physicians and other service providers will be reimbursed. Thus, this system for determining who has earned what portion of payments — keeping score — is likely to be crucially important to the success of these new models of care.

Read the article to understand the ACO’s and our global payment future.

Medicynical Note:  What’s missing from these interventions is control of the constant upward pressure on health care costs from suppliers, often with patent protected monopolies. 

It’s hard to imagine a single diagnostic test costing thousands, single drugs of any sort, much less ones of questionable efficacy, costing more the average and median family income for a year.  Yet that is the reality in our current non-system.  Until these excessive and irrational cost issues are addressed the system will continue to fail.  Health reform is a start but reining in profit expectations at all levels and patent reform are additional needs. 

But, always a but, with our Congress in the pay of medical industrial complex real cost containment seems a long shot.

More on Avastin (bevacizumab) in Breast Cancer– $400,000/patient

There has been much written about the rather minor improvement in breast cancer outcomes with Avastin (bevacizumab).  My last post pointed out one theoretical problem with use of this drug in cancer.

In this week’s NEJM there  are two studies, reporting a small beneficial effect with bevacizumab in patients with early HER2-negative breast cancer.  The authors of one study  note:  (other study here)

The addition of bevacizumab to neoadjuvant chemotherapy significantly increased the rate of pathological complete response among patients with HER2-negative early-stage breast cancer. Efficacy was restricted primarily to patients with triple-negative tumors, in whom the pathological complete response is considered to be a reliable predictor of long-term outcome.

In the study 1948 newly diagnosed breast cancer patients were randomized to receive chemotherapy alone or with concomitant bevacizumab before surgery (neoadjuvant treatment).  The results showed that pathological complete response  was 18.4% in patients receiving bevacizumab and 14.9% without it.  A difference of 3.5%, hardly significant.  In patients with triple negative tumors (ER, PR and HER2 negative) the results were more impressive with 27.9% pathologic complete remission without bevacizumab and 39.3%   with it.  There was no difference in the 1262 ER PR positive patients.  (7.8 and 7.7%)

We don’t know at this time whether the improved CR rate in these patients will translate into improved survival and hopefully cures.

Medicynical Note:  What we can determine however is the cost of the intervention.  Consider the 663 patients that were triple negative.  I assume that about half (I don’t have full access to the article), let’s say 330 patients received bevacizumab.  Then lets take the 39.3% complete response rate,11.6% more than those not receiving the drug, and do a rough estimate of cost. 

39.3% of 330 is 129.69 patients achieved complete remission.  11.6% or 38.38 patients was the incremental benefit.  Assuming a cost in the range of $50,000 for a 3-5 month course of treatment, the total cost of treating these 330 patients with the best outcome in the study would be (paying market prices for the drug) in the range of 16 and a half million dollars.  Dividing that by the incremental benefit of 38.38 the cost of the benefit/patient  was $429,911.

Cost is a real problem for a health care non-system that spends 17% of GDP on health care,  almost twice that of other countries.  Can we afford an intervention that costs over $400,000/patient who benefits?  

I have no particular bias against Avastin (bevacizumab) except for the fact that it (and other similar drugs) appears to have very limited efficacy and is so expensive.  If it were a drug costing $5000-10,000 for a course of treatment I’d say give it a try.  At the present cost and level of efficacy it’s hard to find a strong argument for it’s use, except that it must make the manufacturers and their stockholder a great deal of profit.

Avastin (bevacizumab), Sutent (sunitinib)– Fundamental Problems in Cancer Treatment

There is wide documentation of the relative ineffectiveness of Avastin (bevacizumab) in breast cancer.  The drug simply doesn’t extend the lives of those treated significantly. 

Why?  It ‘s been an open question with the drug company maintaining that the drug costing between $75,000 and $120,000/year for treatments has some effect and that is enough to warrant it’s continued use.  The FDA differed and removed the breast cancer indication, though some insurers for some some reason continue to pay.

There is now an explanation why the drug failed.

Antiangiogenic therapy has been thought to hold significant potential for the treatment of cancer. However, the efficacy of such treatments, especially in breast cancer patients, has been called into question, as recent clinical trials reveal only limited effectiveness of antiangiogenic agents in prolonging patient survival. New research using preclinical models further suggests that antiangiogenic agents actually increase invasive and metastatic properties of breast cancer cells. We demonstrate that by generating intratumoral hypoxia in human breast cancer xenograpfts, the antiangiogenic agents sunitinib and bevacizumab increase the population of cancer stem cells. 

If the finding is confirmed it provides an explanation of the mediocre results in breast and other cancers for this drug.  It raises question about it’s continued use and certainly would argue against using it alone either as a primary treatment or maintenance therapy option.

Medicynical Note:  One hopes this is new information and that the drug company was not previously aware of the increase population of stems cell generated by presumed antiangiogenic caused hypoxia. 

More broadly, how can it be that our pharmaceutical industry sells drugs (sometimes even effective drugs) at twice the median and average income of citizens.  This is not a sustainable model either for business or for health care.

There’s obviously something wrong with our drug development system; drug patents: our non-system of health care; and our payment schemes.  If we ultimately want to reform health care these issues need to be addressed.

Malaria: Artemisinin, Antimalarial with a political agenda

Fascinating story of the development of artemisinin, a antimalarial developed in China during the Vietnam era. 

Artemisinin’s discovery is being talked about as a candidate for a Nobel Prize in Medicine. Millions of American taxpayer dollars are spent on it for Africa every year.

But few people realize that in one of the paradoxes of history, the drug was discovered thanks to Mao Zedong, who was acting to help the North Vietnamese in their jungle war against the Americans. Or that it languished for 30 years thanks to China’s isolation and the indifference of Western donors, health agencies and drug companies.

Medicynical Note:  Perversely, the delay in development and distribution prevented it’s wide use, and perhaps the development of resistance.  It remains an effective agent.

The AVASTIN Spin Machine: Costs $100,000, little proof of survival benefit, But……..

It’s remarkable how drug companies spin the limited proven benefits of their new drugs.   This in the LA Times:

Avastin can stabilize tumors in ovarian cancer, studies find

Two independent groups working with advanced-stage cases say the drug extended the period before the disease worsened by more than 3.5 months.

At this point there is little data indicating that people with ovarian cancer treated with Avastin (bevacizumab) live longer. 

Medicynical Note:  In the past the end points for a cancer treatment advance was actual proof of shrinkage of tumor masses and a significant survival benefit.  In recent years companies have tried to sell “delay in progression” as proof of benefit.  Often as not however, this “delay”, when found, is not repeatable on follow-up trials and/or there was no observed survival benefit.    That was the case when the FDA deauthorized this same drug’s use in breast cancer because the short delay in progression was not replicated and did not increase breast cancer patients’ length of life.

The problems with Avastin are it’s outrageous price, in the range of $100,000/year and the apparent fact that it is only marginally effective.  This type drug is marketed to desperate patients with life threatening illness and priced way out of proportion to it’s benefit, or even development costs.  It is a fact that most of the early development costs came not from drug companies but rather from taxpayers in the form of research grants.

At a cost to consumers and insurers of nearly $100,000/year, more than practically any other consumer purchase, and just a few months delay in progression–Would you buy a $100,000 car that lasted 3.5 months?–it’s hard to be enthusiastic .
