St. Louis, March 30, 2011 – Ther-Rx Corporation takes very seriously the public concerns raised regarding the list price of Makena. We are committed to ensuring that this significant, FDA-approved medication is covered at an affordable cost and accessible to all women who are prescribed Makena. We are finalizing solutions to the concerns, and will announce them by the end of the week.

We share the Food and Drug Administration’s (FDA) long-standing position to ensure that patients have access to FDA-approved medications. We also believe having available an FDA-approved medication is in the best interest of patients. Makena is closely controlled by FDA regulations to monitor safety, efficacy and quality. As an FDA-approved drug, Makena is manufactured in an FDA-regulated and FDA-compliant sterile facility. The manufacturing process is tightly controlled to ensure quality and consistency from dose to dose. This includes follow-up testing and reporting requirements that continue for the lifecycle of the medication.

Prior to FDA approval of Makena, women who could benefit from therapy faced potential barriers to access due to the absence of a commercially-available, FDA-approved product. A survey of obstetricians/gynecologists published in the American Journal of Perinatology in March 2009 highlights concerns about availability in the absence of an FDA-approved product. More than one in three OB/Gyns were “very concerned” about availability.

To address these unmet needs, Ther-Rx took important steps to bring Makena to market and ensure access to therapy upon FDA approval of Makena. Ther-Rx has invested or committed over a quarter of a billion dollars to-date to bring Makena to market, including more than $50 million in research and clinical trial costs, including those associated with conducting major, multi-year follow-on health studies of Makena involving 1,700 mothers and more than 500 infants.

To remove financial barriers to access, Ther-Rx established and has activated a patient financial assistance program (PAP) that not only reduces the total out-of-pocket costs for qualified patients, but eliminates out-of-pocket costs entirely for patients whose financial need is greatest. The level of assistance already exceeds many federal program guidelines for healthcare subsidies. Based on the feedback the company has received, we are currently exploring additional ways to help provide affordable access for all patients who are prescribed Makena. This includes the expansion of the existing patient assistance program.

Specialty injectable products like Makena are not typically carried by retail pharmacies. To make the process of prescribing and obtaining Makena as easy as possible for healthcare providers and patients, Ther-Rx established the Makena Care Connection™, a comprehensive program for patients and healthcare providers that provides administrative, financial, and treatment support for Makena patients in one single point of contact. The Makena Care Connection is actively processing prescriptions for Makena, and is already facilitating access to the financial assistance program for patients in financial need.

It is our commitment that every woman who is prescribed Makena will have affordable access to this FDA-approved and FDA-monitored therapy.
