How Much Should Cancer Drugs Cost?
Memorial Sloan Kettering doctors create pricing calculator that weighs factors such as side effects, extra years of life
One of the nation’s top cancer hospitals is challenging the pharmaceutical industry to adopt a more rational approach to drug pricing.
Memorial Sloan Kettering Cancer Center in New York has created an interactive calculator that compares the cost of more than 50 cancer drugs with what the prices would be if they were tied to factors such as the side effects the drugs produce, and the amount of extra life they give patients. In many cases, the website calculates a price that is lower than the drug’s market price.
The project, led by Peter Bach, a physician and director of the hospital’s Center for Health Policy and Outcomes, is the latest salvo from doctors and others against the escalating costs of cancer drugs, which increasingly carry price tags of $100,000 or more per patient for a year or a course of treatment. A colleague of Dr. Bach’s at Memorial Sloan Kettering recently blasted cancer drug prices as excessive in a speech before thousands of cancer doctors at a meeting in Chicago.
In an interview, Dr. Bach said prices for many new cancer drugs don’t reflect their value to doctors and patients. “Right now, manufacturers have total price control, and total control of prices has led to irrational pricing behaviors,” he said.
To model what he calls “value based” pricing, Dr. Bach created the “DrugAbacus” research tool, which he hopes will get drug makers, insurers, doctors and patients talking about the factors that should determine price.
“We could have a value-driven system for pricing cancer drugs and probably other drugs, and here’s a first draft of how to do it,” he said.
The home page of the website (www.drugabacus.org) features images of Merck & Co.’s melanoma treatment, Keytruda, and Novartis AG’s Gleevec for a form of leukemia. The site lists their per-bottle price—$2,500 for Keytruda and $9,000 for Gleevec—and then asks: “But is that the right price? Should they cost more? Or less?”
The calculator is presented in the form of an abacus with two beads on each wire representing two different prices: the actual price as an immovable bead, and the “abacus” price, which slides up or down based on different factors chosen by the user.
For instance, a user can select what he sees as the monetary value of an additional year of life, ranging from $12,000 to $300,000. Other adjustable components include a “toxicity discount,” which lowers the price to reflect the severity of drug side effects; and cost of development, which can move the price higher based on the number of patients in clinical trials.
When the value of a year of life is set at $120,000, with a toxicity discount that subtracts 15% off that level, the abacus price for many of the drugs is lower than the actual market price. A few have significant gaps at those settings, including Amgen Inc.’s Blincyto, approved by the U.S. Food and Drug Administration in December for the treatment of a rare type of leukemia. The market price for Blincyto is listed on Dr. Bach’s site as $64,260 a month, but the suggested abacus price is just $12,612.
Dr. Bach said Blincyto should be discounted because many patients must be hospitalized to undergo the start of treatment to allow monitoring for side effects, which adds to the cost of administering the drug.
An Amgen spokeswoman said Blincyto is the first major treatment advance for patients with a rare type of leukemia, who typically live just three to five months after diagnosis.
“The price of Blincyto reflects the significant clinical, economic and humanistic value of the product to patients and the health-care system,” the Amgen spokeswoman said. “The price also reflects the complexity of developing, manufacturing and reliably supplying innovative biologic medicines.”
Dr. Bach has previously challenged the drug industry on prices. In 2012, Memorial Sloan Kettering decided not to give Sanofi SA’s new drug, Zaltrap, to colorectal cancer patients because Dr. Bach and other doctors there believed its efficacy didn’t justify its $11,000-per-month price tag. The doctors wrote a newspaper editorial laying out their decision. Sanofi subsequently cut the price by 50% for U.S. oncologists.
Dr. Bach said he got the idea to develop a price calculator in meetings he has had with drug companies, insurers and patients, during which he started writing down various components of what should determine price. Dr. Bach stopped seeing patients about four years ago to focus on research, but says he was also inspired by hearing stories of patients who didn’t fill prescriptions because they couldn’t afford the out-of-pocket costs, which are linked to the overall price.
‘Currently cancer drug prices aren't linked to the benefit they provide. They’re currently priced on what the market can bear, which is an unsustainable system.’
Dr. Bach and two workers in his office spent much of the past two months setting up the site, with help from contractors at Real Endpoints, a drug-cost analysis firm, and engineers from software firm NetQuarry. Memorial Sloan Kettering funded the costs, which Dr. Bach estimated were in the “low six figures.”
Some drugs fare well on the abacus when set at $120,000 for a year of life, and a 15% toxicity discount. Teva Pharmaceutical Industries Ltd.’s Treanda treatment for blood cancers has an “abacus” price of $21,227 a month, well above the actual price of $7,725. A Teva spokeswoman said the company is pleased to see Treanda’s value to patients recognized.
Daniel Goldstein, a medical oncologist at Winship Cancer Institute of Emory University who has researched cancer-drug pricing, said Dr. Bach’s site provides a starting point for value-based pricing.
“Currently cancer drug prices are not linked to the benefit they provide,” Dr. Goldstein said in an interview. “They’re currently priced on what the market can bear, which is an unsustainable system.”
Patricia Danzon, a professor of health-care management at the Wharton School of the University of Pennsylvania, said assigning a monetary value to an additional year of life and discounting a drug’s toxicity should be key components of any pricing system. The ability to adjust the monetary value on Dr. Bach’s website is helpful, she said, because different health payers may be more willing to assign higher values and pay higher prices.
But she said she takes issue with the online calculator’s inclusion of such factors as a drug’s novelty, or its cost of development.
“That’s essentially saying companies should be reimbursed for whatever they spend,” she said in an interview. “That’s not how a competitive market works. In a competitive market, prices reflect the value that the products give to consumers.”
