Most interesting - here's the FDA's latest statement on Makena, in response to KV Pharmaceuticals sending letters to compounding pharmacies telling them to stop providing the drug, now that they have regulatory approval and market exclusivity:
. . .Because Makena is a sterile injectable, where there is a risk of contamination, greater assurance of safety is provided by an approved product. However, under certain conditions, a licensed pharmacist may compound a drug product using ingredients that are components of FDA approved drugs if the compounding is for an identified individual patient based on a valid prescription for a compounded product that is necessary for that patient. FDA prioritizes enforcement actions related to compounded drugs using a risk-based approach, giving the highest enforcement priority to pharmacies that compound products that are causing harm or that amount to health fraud.
FDA understands that the manufacturer of Makena, KV Pharmaceuticals, has sent letters to pharmacists indicating that FDA will no longer exercise enforcement discretion with regard to compounded versions of Makena. This is not correct.
In order to support access to this important drug, at this time and under this unique situation, FDA does not intend to take enforcement action against pharmacies that compound hydroxyprogesterone caproate based on a valid prescription for an individually identified patient unless the compounded products are unsafe, of substandard quality, or are not being compounded in accordance with appropriate standards for compounding sterile products. As always, FDA may at any time revisit a decision to exercise enforcement discretion.
The agency does not quite make clear that the "unique situation" might be, although they do mention the amount of work done by NIH-funded researchers that was part of the approval package. The FDA has, of course, no authority on pricing - but they do have other means at their disposal, and this is one of them. KV must be wondering at this point what, exactly, the phrase "market exclusivity" might mean. (The answer, for better or worse, is that it, and other statuatory language, means whatever the regulatory authorities want it to mean, at least until something goes to the courts. Then it means whatever the courts want it to mean).
Overall, I think that this is a good thing, since (as I've said before) I think that the law in this case is providing a bit too much incentive, considering the relatively small risks involved in bringing progesterone caproate into the modern regulatory world. It worries me, though, that the FDA is making it so explicit that they plan to pick and choose which laws to enforce and how strictly they're going to enforce them. But honestly, it's always been this way, and a no-exceptions letter-of-the-law approach leads to craziness of its own. In this case, I think that clarifying the hazards of pushing things as hard as they can possibly be pushed will help make future business plans in this area a bit more realistic.
