Even although the $550 yellow capsules offered as Korlym have a controversial origin because the abortion capsule, Leslie Edwin says they “gave me life.”
The 40-year-old Georgia resident lives with Cushing’s syndrome, a doubtlessly lethal situation that causes excessive ranges of the hormone cortisol to wreak havoc on a physique. When first identified, she mentioned, she gained about 100 kilos, her blood sugars had been “out of control,” and he or she suffered pimples, the shortcoming to sleep and fixed anxiousness.
“I wouldn’t leave the house,” Edwin mentioned of her first bout with the situation. “I quit my job after a certain point. I just couldn’t keep being in front of people.”
That’s when Edwin endured surgical procedures, together with one to take away her pituitary gland. She went into remission, however then, in 2016, her weight shot up 30 kilos and the anxious emotions returned. Her docs prescribed Korlym.
The drug’s energetic ingredient is mifepristone, as soon as known as RU-486 and higher often known as the abortion capsule as a result of it causes a miscarriage when taken early in a being pregnant. Nearly 20 years in the past, Danco Laboratories received approval to market Mifeprex within the U.S. because the abortion drug, with tight restrictions on use. Corcept Therapeutics, a Silicon Valley-based drug firm, started advertising and marketing Korlym six years in the past as a specialty drug for about 10,000 rare-disease sufferers akin to Edwin.
The distinction in worth between Korlym and Mifeprex is placing, despite the fact that the elements are the identical: One 200-milligram capsule to immediate an abortion prices about $80. In distinction, a 300-milligram capsule prescribed for Cushing’s runs about $550 earlier than reductions. Patients wanting an abortion take just one capsule. People with Cushing’s typically take as much as three capsules a day for months or years.
Dr. Joseph Belanoff, chief government of the drug’s maker, Corcept, mentioned Korlym’s common value per affected person is $180,000 yearly and concedes that “we have an expensive drug. There’s no getting around that.”
The story of Korlym highlights how America’s drug growth system can flip an previous drug into a brand new one which treats comparatively
few — however typically very determined — sufferers.
When the Food and Drug Administration permitted Korlym in 2012, it was designated as an orphan drug, giving Corcept seven years of market exclusivity in addition to different financial incentives. Congress permitted orphan drug incentives to encourage the event of medicines for uncommon ailments that have an effect on fewer than 200,000 sufferers. Since the drug’s approval, Korlym’s worth has risen about 150 %, and final 12 months the corporate’s income practically doubled to $159.2 million. (Korlym is the corporate’s solely product and treats about 1,000 sufferers within the U.S.)
“You can hike that drug [price] 50 percent or 80 percent, and if there is backlash you can walk it back,” mentioned Dr. Joshua Liao, an affiliate medical director at University of Washington Medicine.
Corcept has steadily elevated the value with little backlash.
Belanoff mentioned the income from Korlym pay for the corporate’s previous spending on the drug’s analysis and growth in addition to its effort to create new medication. The firm final month reported an encouraging Phase 2 trial replace on Korlym’s successor, relacorilant, a drug that might deal with Cushing’s with out the negative effects for some girls of endometrial thickening and potential vaginal bleeding.
The firm’s pipeline can be stuffed with potential oncology medication that maintain the promise of utilizing molecules to affect the cortisol receptors, with wide-ranging results within the physique. Korlym together with one other drug is being examined for the remedy of metastatic triple-negative breast most cancers, which tends to be extra aggressive than different sorts of breast most cancers. And relacorilant is within the very early levels of testing to deal with castration-resistant prostate most cancers.
While most of the second-generation medication should not associated to Korlym structurally, Korlym did “provide the funding. … If there had not been orphan-drug pricing and the [Orphan Drug] Act, you would have to look for a different way to develop those drugs,” Belanoff mentioned.

Korlym got here to market in 2012 with a mean wholesale worth of $223.20 per capsule earlier than reductions, based on the well being care know-how agency Connecture. Corcept boosted the value $20 to $50 every year. By December 2017, every capsule had a mean wholesale worth of $549.60 earlier than any reductions or rebates had been negotiated for sufferers.
Alan Leong, senior analysis analyst and proprietor of BioWatch, who follows Corcept, mentioned he thought the corporate may fail at one level however famous that Belanoff “played the odds” with Korlym and received.
So far, incrementally rising Korlym’s worth whereas including sufferers has paid off. Corcept’s inventory soared 27.four % in January earlier than Teva Pharmaceutical Industries introduced it had filed an utility for a generic model on the drug. Teva declined to remark for this story.
Belanoff mentioned he want to know the place Teva obtained sufficient doses of Korlym to efficiently take a look at a generic: “We have a single pharmacy and a single manufacturer and the medicine has to be [FedEx’ed] to the patient.”
Talking to analysts final month, Corcept Chief Financial Officer Charlie Robb mentioned the influence of Teva’s generic submitting for the subsequent few years is “nothing but litigation, which we can comfortably afford.”
Corcept’s executives count on revenues to maintain climbing, reaching $275 million to $300 million in 2018 — an expectation that has not modified regardless of Teva’s announcement.
A ‘Pioneering Substance’
Cushing’s syndrome occurs when the physique produces an excessive amount of of the highly effective hormone cortisol, which usually helps maintain the cardiovascular system functioning effectively and permits the physique to show proteins, carbohydrates and fat into vitality. But an excessive amount of cortisol could be harmful. It could cause cognitive difficulties, melancholy, fatigue, hypertension, bone loss and, in some instances, Type 2 diabetes. Those affected by the syndrome can develop a fatty hump between their shoulders and a rounded face. Without remedy, sufferers can die of a wide range of problems, together with sepsis after the hormone compromises the immune system.
Mifepristone, the energetic ingredient in Korlym, helps Cushing’s sufferers by blocking the physique’s means to course of cortisol. It induces an abortion by blocking the physique’s receptor for progesterone, which causes the uterine wall to interrupt down.
When the FDA permitted Korlym for a particular set of Cushing’s sufferers, the company required a “TERMINATION OF PREGNANCY” warning field on the high of the label.
Dr. Constantine Stratakis, a senior investigator and scientific director on the National Institute of Child Health and Human Development who focuses on treating individuals with Cushing’s syndrome, calls mifepristone a “pioneering substance” as a result of it “has a lot of crossover” to different receptors within the physique.
That means the drug has numerous potential makes use of. Belanoff and Dr. Alan Schatzberg, a Stanford University psychiatrist and scientist, co-founded Corcept in 1998 to discover whether or not mifepristone may assist deal with main melancholy. In 2002, Schatzberg mentioned the drug “will be the equal of shock treatments in a pill.”
But medical trials didn’t again up the declare. Schatzberg rotated off the board and left the corporate in 2007, saying the corporate “went in a different direction.” A congressional investigation also questioned whether or not Schatzberg had conflicts of curiosity as the federal government’s principal investigator overseeing medical trials and a co-founder of Corcept, which had awarded him inventory choices.
In response to the congressional investigation, Stanford mentioned Schatzberg was totally compliant with its inside conflict-of-interest coverage.
Leong of BioWatch recollects the transition to Cushing’s analysis as a troublesome time for Corcept. But after the “psychiatric depression program shut down, [Belanoff] stuck to it,” Leong mentioned.
Corcept’s “Hail Mary” second got here in 2007. The firm filed an utility to see whether or not mifepristone may work for Cushing’s sufferers. (Cushing’s impacts about 20,000 individuals within the U.S., however Corcept executives say the situation typically goes undiagnosed.)
Developing the drug value about $300 million, Belanoff estimates, and concerned long-term toxicology checks to make sure that sufferers may safely take greater doses for months or years. As an orphan drug, a portion of Korlym’s analysis and growth prices might be written off. For instance, Corcept reported in 2013 that it had $19.7 million in federal tax credit.
And whereas Korlym’s annual prices pale in opposition to different specialty medication, which run as excessive as $750,000 a 12 months, the climbing price ticket and rising variety of sufferers do have an effect on the well being care system.
“It’s like an unseen cost and then down the road this is a huge cost burden,” mentioned the University of Washington’s Liao.
Most sufferers are coated by non-public insurance coverage, Belanoff mentioned, however Medicare and Medicaid are paying for the drug as effectively. According to Medicare Part D data, 52 Korlym sufferers value Medicare $2.6 million in 2013. Two years later in 2015, 115 beneficiaries filed claims of $11.four million.
In Georgia, Leslie Edwin is on non-public insurance coverage and describes herself as being in “a really high tax bracket” but she by no means paid greater than $25 a month by Corcept’s affected person help program known as SPARK (the Support Program for Access and Reimbursement for Korlym).
“Across the board, it would be very difficult to find any patient that pays the full price,” mentioned Edwin, who volunteers as president of the nonprofit affected person advocacy group Cushing’s Support and Research Foundation. The small group, which reported $50,000 in contributions and grants in 2015, notes on its website that Corcept in addition to Novartis Oncology present monetary help to the group. Edwin isn’t paid, and the group’s federal tax submitting particulars that almost all of its bills go to distributing a quarterly e-newsletter, contacting members and sufferers “to promote mission,” and offering referrals to docs.
Belanoff mentioned he believes Corcept has a “social contract” to handle sufferers and pledged that any affected person who’s prescribed Korlym will get it no matter insurance coverage protection or prices.
“We were starting with a notorious drug, and the growth has been steady from a very low base over time,” Belanoff mentioned, emphasizing that the “single most important thing” is that the drug works very effectively.
Dr. Sherwin D’Souza at St. Luke’s Boise Medical Center in Idaho prescribed Korlym for the primary time final 12 months to Vonda Huddleston, figuring out the corporate would offer monetary help till Huddleston may get insurance coverage to pay for surgical procedure.
Huddleston, although, recalled worrying concerning the worth and what it could value her out-of-pocket. The firm supplied her first two months’ value at no cost and requested her to name again when she was enrolled for insurance coverage.
“They were so eager to get me on this medication,” she mentioned.
