WALTHAM, Mass., Nov. 18, 2015 (GLOBE NEWSWIRE) -- AMAG Pharmaceuticals, Inc. (Nasdaq:AMAG) today received a complete response letter (CRL) from the U.S. Food and Drug Administration (FDA) for its application seeking approval for a single-dose vial of Makena (hydroxyprogesterone caproate injection) to reduce the risk of preterm birth in certain at-risk patients. A CRL is a communication from the FDA that informs companies that an application cannot be approved in its present form. In the letter, the FDA requested additional information and the company is working with its manufacturer to submit a response with the requested information to the FDA as quickly as possible.
"While we are disappointed by this delay, we believe the single-dose, preservative-free vial is an important step in our next generation development program for Makena, and we remain committed to working with the FDA to bring this product to market," stated William Heiden, chief executive officer of AMAG. "Improving the healthcare provider and patient experience with Makena through the development of customer-friendly line extensions is a key priority for the company."
Makena, the only FDA-approved treatment indicated to reduce the risk of preterm birth in women who are pregnant with one baby and who have spontaneously delivered one preterm baby in the past, is currently marketed in a multi-dose vial, containing five weekly injections. The multi-dose Makena vial remains available for prescribing and is not affected by the letter from FDA regarding the single-dose application.

About Makena® (hydroxyprogesterone caproate injection)
Makena® is a progestin indicated to reduce the risk of preterm birth in women with a singleton pregnancy who have a history of singleton spontaneous preterm birth. The effectiveness of Makena is based on improvement in the proportion of women who delivered <37 weeks of gestation. There are no controlled trials demonstrating a direct clinical benefit, such as improvement in neonatal mortality and morbidity.
Limitation of use: While there are many risk factors for preterm birth, safety and efficacy of Makena has been demonstrated only in women with a prior spontaneous singleton preterm birth. It is not intended for use in women with multiple gestations or other risk factors for preterm birth.
Important Safety Information for Makena (hydroxyprogesterone caproate injection)
Makena should not be used in women with any of the following conditions: blood clots or other blood clotting problems, breast cancer or other hormone-sensitive cancers, or history of these conditions; unusual vaginal bleeding not related to the current pregnancy, yellowing of the skin due to liver problems during pregnancy, liver problems, including liver tumors, or uncontrolled high blood pressure.
Before patients receive Makena, they should tell their healthcare provider if they have an allergy to hydroxyprogesterone caproate, castor oil, or any of the other ingredients in Makena; diabetes or prediabetes, epilepsy, migraine headaches, asthma, heart problems, kidney problems, depression, or high blood pressure.
In one clinical study, certain complications or events associated with pregnancy occurred more often in women who received Makena. These included miscarriage (pregnancy loss before 20 weeks of pregnancy), stillbirth (fetal death occurring during or after the 20th week of pregnancy), hospital admission for preterm labor, preeclampsia (high blood pressure and too much protein in the urine), gestational hypertension (high blood pressure caused by pregnancy), gestational diabetes, and oligohydramnios (low amniotic fluid levels).
Makena may cause serious side effects including blood clots, allergic reactions, depression, and yellowing of the skin and the whites of the eyes. The most common side effects of Makena include injection site reactions (pain, swelling, itching, bruising, or a hard bump), hives, itching, nausea, and diarrhea.
