- Provides Columbia with Financial Support For Progesterone Franchise Product Development -

MORRISTOWN, N.J., June 1 /PRNewswire-FirstCall/ -- Watson Pharmaceuticals, Inc. (NYSE: WPI) today confirmed that Columbia Laboratories, Inc. has filed with the Securities and Exchange Commission a definitive proxy seeking Columbia shareholder approval of the previously announced agreement under which Watson would acquire the U.S. rights to Columbia's CRINONE® and PROCHIEVE® product line and 11,200,000 shares of Columbia common stock.  

Additionally, Watson confirmed that it has entered into a $15 million loan agreement with Columbia to support Columbia's ongoing investment in the clinical development of the pre-term birth indication for PROCHIEVE®, as well as other Columbia capital requirements.  If the acquisition transaction with Columbia closes before December 31, 2011, all principal and accrued interest on the loan will be forgiven.

"Filing the proxy represents a significant step towards the closing of our acquisition, which will permit both Watson and Columbia shareholders to begin to realize the value of our proposed partnership," said Paul Bisaro, Watson's President and Chief Executive Officer.  "Our forgivable loan to Columbia demonstrates Watson's commitment to supporting the clinical development activities related to PROCHIEVE's expanded pre-term birth indication and to our collaboration with Columbia.  If Columbia and Watson are successful in receiving FDA approval for a new pre-term birth indication, we will have the opportunity to address a significant and unmet medical need."

The acquisition remains subject to customary closing conditions, including the approval of Columbia's stockholders.  After the close of the acquisition, Watson intends to immediately begin marketing CRINONE® and PROCHIEVE® for approved indications in the U.S. to reproductive endocrinologists and Ob/Gyns through the existing Brand Sales Forces.  

CRINONE® is currently used for progesterone supplementation or replacement as part of an Assisted Reproductive Technology (ART) treatment for infertile women with a progesterone deficiency.  Patient preference for CRINONE® has been demonstrated in five clinical trials.  The product is also available under the trade name PROCHIEVE®.

A Phase 3 clinical program is currently underway in collaboration with the National Institutes of Health (NIH) to evaluate the safety and efficacy of PROCHIEVE® for the prevention of pre-term birth in women with a short cervix.  Pre-term birth occurs in one of every eight live born infants, and short cervix is the single most important predictor of pre-term birth.  There are currently no products approved for the prevention of pre-term birth.

Important Safety Information

The most common side effects of CRINONE® include breast enlargement, constipation, somnolence, nausea, headache, and perineal pain.  CRINONE® is contraindicated in patients with an active thrombophlebitis or thromboembolic disorders, missed abortion, undiagnosed vaginal bleeding, liver dysfunction or disease, and known or suspected malignancy of the breast or genital organs.
