I wanted to do some follow-up on the Makena story – the longtime progesterone ester drug that has now been newly FDA-approved and newly made two order of magnitude more expensive. (That earlier post has the details, for those who might not have been following).
Steve Usdin at BioCentury has, in the newsletter’s March 21st issue, gone into some more detail about the whole process where KV Pharmaceuticals stepped in under the Orphan Drug Act to pick up exclusive marketing rights to the drug. The company, he says, “arguably has played a marginal role” in getting the drug back onto the market.
Here’s the timeline, from that article and some digging around of my own: in 1956, Squibb got FDA approval for the exact compound (progesterone caproate) for the exact indication (preventing preterm labor), under the brand name Delalutin. But at that time, the FDA didn’t require proof of efficacy, just safety. There were several small, inconclusive academic studies during the 1960s. In 1971, the FDA noted that the drug was effective for abnormal uterine bleeding and other indications, and was “probably effective” for preventing preterm delivery. In 1973, though, based on further data from the company, the agency went back on that statement, and said that there was now evidence of birth defects from the use of Delalutin in pregnant women, and removed any of these as approved uses. In the late 1970s, warning language was further added. In 1989, the agency said that its earlier concerns (heart and limb defects) were unfounded, but warned of others. By 1999, the FDA had concluded that progesterone drugs were too varied in their effects to be covered under a single set of warnings, and took the warning labels off.
In 1998, the National Institute of Child Health and Human Development launched a larger, controlled study, but this was an example of bad coordination all the way. By this time, Bristol-Myers Squibb had requested that Delalutin’s NDAs be revoked, saying that they hadn’t even sold the compound for several years. This seems to have also been a move, though, in response to FDA complaints about earlier violations of manufacturing guidelines and a request to recall the outstanding stocks of the drug. So the NICHD study was terminated after a year, with no results, and the drug’s NDA was revoked as of September, 2000.
The NICHD had started another study by then, however, although I’m not sure how they solved their supply problems. This is the one that reported data in 2003, and showed a real statistical benefit for preterm labor. More physicians began to prescribe the drug, and in 2008, the American College of Obstetricians and Gynecologists recommended its use.
So much for the medical efficacy side of the story. Now we get back to the regulatory and marketing end of things. In March of 2006, a company called CUSTOpharm asked the FDA to determine if the drug had been withdrawn for reasons of safety or efficacy – basically, was it something that could be resubmitted as an ANDA? The agency determined that the compound was so eligible.
Meanwhile, another company called Adeza Biomedical was moving in the same direction (as far as I can tell, they and CUSTOpharm had nothing to do with each other, but I don’t have all the details). Adeza submitted an NDA in July 2006, under the FDA’s provision for using data that that applicant had not generated – in fact, they used the NICHD study results. They called the compound Gestiva, and asked for accelerated approval, since preterm delivery was accepted as a surrogate for infant mortality. An advisory committee recommended this in August of 2006, by a 12 to 9 vote. (Scroll down to the bottom of this page for the details).
The agency sent Adeza an “approvable” letter in October 2006 which asked for more animal studies. The next year, Adeza was bought by Cytec, who were bought by Hologic, who sold the Gestiva rights to KV Pharmaceuticals in January 2008. So that’s how KV enters the story: they bought the drug program from someone who bought it from someone who just used a government agency’s clinical data.
The NDA was approved by the FDA in February 2011, along with a name change to Makena. By this time, KV and Hologic had modified their agreement – KV had already paid up nearly $80 million, with another $12.5 million due with the approval, and has further payments to make to Hologic which would take the total purchase price up to nearly $200 million. That’s been their main expense for the drug, by far. The FDA has asked them to continue two ongoing studies of Makena – one placebo-controlled trial to look at neonatal mortality and morbidity, and one observational study to see if there are any later developmental effects. Those studies will report in late 2016, and KV has said that their costs will be in the “tens of millions”. So they paid more for the rights to Makena than it’s costing them to get it studied in the clinic.
That only makes sense if they can charge a lot more than the generic price for the drug had been, of course, and that’s what takes us up to today, with the uproar over the company’s proposed price tag of $1500 per treatment. But the St. Louis Post-Dispatch (thanks to FiercePharma for the link) says that the company has now filed its latest 10-Q with the SEC, and is notifying investors that its pricing plans are in doubt:
The success of the Company’s commercialization of Makena™ is dependent upon a number of factors, including: (i) the Company’s ability to maintain certain net pricing levels for Makena™; (ii) successfully obtaining agreements for coverage and reimbursement rates on behalf of patients and medical practitioners prescribing Makena™ with third-party payors, including government authorities, private health insurers and other organizations, such as HMOs, insurance companies, and Medicaid programs and administrators, and (iii) the extent to which pharmaceutical compounders continue to produce non-FDA approved purported substitute product. The Company has been criticized regarding the list pricing of Makena™ in a number of news articles and internet postings. In addition, the Company has received, and expects to continue to receive, letters criticizing the Company’s list pricing of Makena™ from several medical practitioners and several advocacy groups, including the March of Dimes, American College of Obstetricians and Gynecologists, American Academy of Pediatrics and the Society for Maternal Fetal Medicine. Further, the Company has received one letter from a United States Senator and expect to receive another letter from a number of members of the United States Congress asking the Company to reduce its indicated pricing of Makena™, and the same Senator, together with a second Senator, has sent a letter to the Federal Trade Commission asking the agency to initiate an investigation of our pricing of Makena™.
The Company is responding to these criticisms and events in a number of respects. . .The success of the Company is largely dependent upon these efforts and appropriately responding to both the media and governmental concerns regarding the pricing of Makena™.
Personally, I’m torn a bit by the whole situation. I think that people and companies have the right to charge what the market will bear for their goods and services. But at the same time, I find myself also very irritated by KV in this case, because I truly think that they are taking advantage of the regulatory framework. As I said in the last post, it’s not like they took on much risk here – they didn’t discover this drug, didn’t do the key clinical work on it, and don’t even manufacture it themselves. Their business plan involves sitting back and collecting the rent, but that’s what the law allows them to do.
In the end, if political pressure forces them to back down on their pricing, this will come down to a poor business decision. Companies should, in fact, charge what the market will bear – but KV may have neglected some other factors when they calculated what that price should be. Before setting a price, you should ask “Will the insurance companies pay?” and “Will Medicare pay?” and “Will people pay out of their own pocket?”, but you should also ask “Will this price bring down so much controversy that we won’t be able to make it stick?”
