A busy day in the preterm-birth drug drama

A great deal happened today in the amazing unfolding drama of a decades-old drug that has been shown to prevent preterm birth:

* KV Pharmaceutical more than halved the cost of Makena, approved by the FDA in February, which debuted at a price of $1,500 per dose. KV Pharmaceutical dropped the price today to $690, and vowed to make sure clinically eligible pregnant women would be able to afford the drug.

* However, the action wasn't enough to stop the March of Dimes from saying it would "step away from" its relationship with Ther-Rx, a subsidiary of the drug company.

"Access (for women) to 17-P is and always has been our paramount concern," Jennifer Howse, March of Dimes president wrote in a letter today to Greg Divis, president of the Ther-Rx Corp., employing a generic term for the drug, hydroxyprogesterone caproate.

In her letter, Howse acknowledged considerable financial support Ther-Rx has given the March of Dimes.

* Sen. Sherrod Brown (D-Ohio) said he was releasing "previously unreported figures showing the scope of taxpayer investment in the development of preterm pregnancy drugs."

A press release from Sen. Brown's office detailed the $21 million he said went into bringing Makena to market, including these costs:

* An initial trial, showing that the injection prevented preterm births in women who have previously had a preterm birth, cost taxpayers $5 million.

* A second trial, at $1.1 million, showed no side effects in children whose mothers had used the formulation.

* A third trial, costing taxpayers $5.1 million, found that the drug did not work to prevent preterm birth in women carrying twins and triplets; according to the NIH, this study was critical for Makena’s orphan drug status determination because an alternative result could have widened the number of potentially eligible women to use the drug.

* A fourth trial, which is still ongoing, cost $7.5 million through Fiscal Year 2010 and aims to find whether 17P treatments are effective at preventing preterm birth in women with shortened cervixes. This is the largest study of 17P by the National Institutes of Health, and could create another category of women eligible for Makena.

But the cost to the public doesn't end there.

In an article in the New England Journal of Medicine last month, Joanne Armstrong MD laid out the cost of treating the roughly 139,000 women she said were likely to need the drug every year. A course of 20 treatments with 17P at $300, the likely price for the drug compounded by a pharmacist, would cost $41.7 million. A course of treatment with Makena (at the original price of $1,500) for one woman would cost $29,000, or $4 billion for all 139,000, many of whom would need to resort to Medicaid to pay for the drug.

The March of Dimes, as saintly in the public eyes as an organization can be, felt the heat from the public for backing KV Pharmaceutical's push for FDA approval of Makena.

"Only after our threats (to boycott March of Dimes fund-raising events) did the MOD firm up their stance," one man wrote on March 25 on the March of Dimes' Facebook page.

But critics, including the Society for Maternal and Fetal Medicine, the American College of Obstetricians and Gynecologists, and the American Academy of Pediatics, saved their strongest language for KV Pharmaceutical.

Sens. Brown and Amy Klobuchar (D-Minn.) asked the Federal Trade Commission to investigate the drug company for "price gouging at the expense of pregnant women."
