NEW YORK — Specialists in infectious disease are protesting a gigantic overnight increase in the price of a 62-year-old drug that is the standard of care for treating a life-threatening parasitic infection.
The drug, called Daraprim, was acquired in August by Turing Pharmaceuticals, a startup run by a former hedge fund manager. Turing immediately raised the price to $750 a tablet from $13.50, bringing the annual cost of treatment for some patients to hundreds of thousands of dollars.
“What is it that they are doing differently that has led to this dramatic increase?” said Dr. Judith Aberg, chief of the division of infectious diseases at the Icahn School of Medicine at Mount Sinai in New York. She said the price increase could force hospitals to use “alternative therapies that may not have the same efficacy.”
Turing’s price increase is not an isolated example. Although most of the attention on pharmaceutical prices has been on new drugs for diseases like cancer, hepatitis C, and high cholesterol, there is also growing concern about huge price increases on older drugs, some of them generic, that have long been mainstays of treatment.
Although some price increases have been caused by shortages, others have resulted from a business strategy of buying old neglected drugs and turning them into high-priced “specialty drugs.”
Cycloserine, to treat dangerous multidrug-resistant tuberculosis, was just increased in price to $10,800 for 30 pills from $500 after its acquisition by Rodelis Therapeutics. Scott Spencer, general manager of Rodelis, said the company needed to invest to make sure the supply of the drug remained reliable. He said the company provided the drug free to certain needy patients.
In August, two members of Congress wrote to Valeant Pharmaceuticals after that company acquired two heart drugs, Isuprel and Nitropress, from Marathon Pharmaceuticals and promptly raised their prices by 525 percent and 212 percent, respectively. Marathon itself had acquired the drugs from another company in 2013 and had quintupled their prices, according to the lawmakers, Senator Bernie Sanders, the Vermont independent who is seeking the Democratic nomination for president, and Representative Elijah E. Cummings, Democrat of Maryland.
Doxycycline, an antibiotic, went from $20 a bottle in October 2013 to $1,849 by April 2014, according to the two lawmakers.
The Infectious Diseases Society of America and the HIV Medicine Association sent a joint letter to Turing this month calling the price increase on Daraprim “unjustifiable for the medically vulnerable patient population” and “unsustainable for the health care system.” An organization representing the directors of state AIDS programs has also been looking into the price increase, according to doctors and patient advocates.
Daraprim, known generically as pyrimethamine, is used mainly to treat toxoplasmosis, a parasite infection that can cause serious or even life-threatening problems for babies born to women who become infected during pregnancy, and also for those with compromised immune systems, like AIDS patients and certain cancer patients.
Martin Shkreli, founder and chief executive of Turing, said the drug is so rarely used that the impact on the health system would be minuscule and that Turing would use the money it earns to develop better treatments for toxoplasmosis, with fewer side effects.
“This isn’t the greedy drug company trying to gouge patients. It is us trying to stay in business,” Shkreli said. He said many patients use the drug for far less than a year and that the price was now more in line with those of other rare disease drugs.
“It really doesn’t make sense to get any criticism for this,” he said.
Daraprim, which is also used to treat malaria, was approved by the FDA in 1953 and has long been made by GlaxoSmithKline. Glaxo sold US marketing rights in 2010 to CorePharma. Last year, Impax Laboratories agreed to buy Core and affiliated companies for $700 million. In August, Impax sold Daraprim to Turing for $55 million, a deal announced the same day Turing said it had raised $90 million from Shkreli and other investors in its first round of financing.

Daraprim cost only about $1 per tablet several years ago, but it went up sharply after CorePharma acquired it. According to IMS Health, which tracks prescriptions, sales of the drug jumped to $6.3 million in 2011 from $667,000 in 2010, even as prescriptions held steady at about 12,700. In 2014, after further price increases, sales were $9.9 million, as the number of prescriptions shrank to 8,821. The figures do not include inpatient use in hospitals.
Turing’s price increase could bring sales to tens or even hundreds of millions of dollars a year if use remains constant. Medicaid and certain hospitals will be able to get the drug inexpensively under federal rules for discounts and rebates. But private insurers, Medicare, and hospitalized patients would have to pay closer to the list price.
Some doctors questioned Turing’s claim that there is a need for better drugs, saying the side effects, while potentially serious, can be managed.
“I certainly don’t think this is one of those diseases where we have been clamoring for better therapies,” said Dr. Wendy Armstrong, professor of infectious diseases at Emory University in Atlanta.
With the price now high, other companies could conceivably make generic copies, because patents have long expired. But Daraprim’s distribution is tightly controlled, making it harder for generic companies to get the samples they need for the required testing.
The switch from drugstores to controlled distribution was made in June by Impax, not by Turing. Still, controlled distribution was a strategy Shkreli talked about at his previous company as a way to thwart generics.
