SAN DIEGO--(BUSINESS WIRE)--Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) announced that its partner Pfizer has received EU marketing authorization for DUAVIVE® (conjugated estrogens/bazedoxifene (BZA/CE)) from the European Commission. In the EU, DUAVIVE™ is indicated for the treatment of estrogen deficiency symptoms in postmenopausal women with a uterus (with at least 12 months since the last menses) for whom treatment with progestin-containing therapy is not appropriate. Ligand will be entitled to a milestone payment following Pfizer obtaining pricing of DUAVIVE® in a major European market.
DUAVIVE® was studied in a Phase 3 clinical development program (Selective estrogens, Menopause And Response to Therapy [SMART] trials), which included approximately 7,500 postmenopausal women and assessed the safety and efficacy of DUAVIVE® for the treatment of estrogen deficiency symptoms, such as moderate-to-severe hot flashes . The most common adverse drug reactions observed in the SMART trials were abdominal pain, vaginal yeast infection and muscle spasms.
DUAVIVE® is pairs conjugated estrogens (CE) with an estrogen agonist/antagonist, also known as a selective estrogen receptor modulator (SERM). DUAVIVE® uses bazedoxifene - instead of a progestin - to help protect the uterine lining against hyperplasia that may result from estrogen alone treatment.
DUAVIVE® should not be used in women who: have or had blood clots; are allergic to any of its ingredients; have unusual vaginal bleeding; have or had certain cancers (e.g. uterine or breast), liver problems, or bleeding disorders; or are pregnant, may become pregnant or are breastfeeding a baby.
About the Ligand/Pfizer Collaboration
DUAVIVE® was developed by Wyeth and was part of a broader research collaboration with Ligand on SERMs. Pfizer acquired the rights to DUAVIVE® when it acquired Wyeth. Under the terms of the agreement, Ligand receives certain payments and royalties from Pfizer on predetermined development and sales milestones.
Menopause is a normal, natural event—it marks the permanent end of fertility and is usually confirmed when a woman has missed her period for 12 consecutive months (in the absence of other obvious causes). Menopause is associated with reduced functioning of the ovaries due to aging, resulting in lower levels of estrogen and other hormones. Declining levels of estrogens can lead to bothersome vasomotor symptoms (VMS) in 60-85% of women undergoing the menopausal transition. With more than 100 million women aged 50 and over in 2011, VMS may affect over 60 million women in the EU1.
