FDA Advisory Panel Finds Hologic's Adiana(R) Permanent Contraception Approvable

Dec 13, 2007, 00:00 ET from Hologic, Inc.

    BEDFORD, Mass., Dec. 13 /PRNewswire-FirstCall/ -- Hologic, Inc.
 (Nasdaq:   HOLX) announced today that the FDA Obstetrics and Gynecology
 Devices Advisory Panel recommended that the pre-market application for
 Adiana(R) Permanent Contraception for female sterilization is Approvable.
 The panel reached this decision by a vote of 10 to 3.
     The FDA is not required to accept, but traditionally follows the
 recommendations of its advisory panels. The panel recommended approval of
 the device contingent upon several conditions, including long-term follow
 up of current pivotal trial patients, a new post approval study of new
 patients and physicians, and more specific labeling recommendations.
     "Women are looking for choices for their long-term contraceptive
 needs," said Ted Anderson, M.D., Ph.D., Associate Professor of Obstetrics
 and Gynecology at Vanderbilt University Medical Center, and clinical
 investigator of the pivotal clinical trial for Adiana. "Adiana provides a
 novel, safe and effective permanent transcervical alternative to tubal
 ligation. The procedure takes approximately 15 minutes to perform without
 the risky and uncomfortable side effects experienced with a more invasive
 surgical procedure but with comparable efficacy in avoiding pregnancy as
 underscored by the results of the clinical trials where the device was
 evaluated in more than 600 women."
     Bilateral tubal ligation -- commonly referred to as "getting your tubes
 tied" -- is the most common form of contraception used throughout the
 world. Approximately 700,000(1) tubal ligation surgical procedures are
 performed annually in the U.S. alone. The surgery is typically performed in
 a hospital operating room under general anesthesia and requires the
 physician to make one or two incisions in the abdomen. This usually
 requires approximately four to five days of recuperation.
     In contrast, Adiana is a minimally-invasive, non-incisional
 alternative. This procedure uses hysteroscopy, generally requires only
 local anesthesia, and can be performed in a physician's office. Patients
 are typically able to return to work or resume their everyday activities
 within a day.
     "Contraception is obviously a critical decision for any woman," said
 Sue Knapton, a 46-year-old woman who participated in the clinical trial of
 Adiana. "This seemed to me to be the better choice than more invasive
 surgery or long- term use of oral contraceptives. I am glad I was able to
 participate in the Adiana trial and hope other women will benefit from
 Adiana in the future."
     "Today represents a tremendous milestone in enabling us to realize our
 goal in making Adiana a viable and better alternative for women looking for
 permanent contraception. We will work closely with the FDA to address any
 remaining issues and expedite final approval. We are confidently on course
 to provide women with an important new treatment option," said Tony
 Kingsley, President, Hologic GYN Surgical Products.
     The pivotal clinical trial to demonstrate the safety and effectiveness
 of Adiana in providing permanent contraception was conducted in the U.S.,
 Australia, and Mexico. As part of the clinical trial, 645 women between the
 ages of 21 and 45 had treatment attempted with Adiana. The procedure showed
 a strong safety profile, with very high device placement success, patient
 tolerance, comfort and satisfaction. A pregnancy prevention efficacy rate
 of 98.9 percent after 12 months of reliance on Adiana was demonstrated,
 successfully meeting the trial's primary endpoint. This efficacy result
 also compares favorably with the results of the CREST Study (U.S.
 Collaborative Review of Sterilization), which examined the long-term
 failure of tubal ligation for sterilization.
     About Adiana Permanent Contraception
     Adiana is a novel, two-step approach to permanent contraception. First,
 a catheter is positioned immediately inside the opening of the patient's
 fallopian tube using a hysteroscope, eliminating the need for any
 incisions. The catheter applies a very low-level of bi-polar radiofrequency
 (RF) energy to remove just a thin layer of cells that line a 1cm section of
 the inside of the fallopian tube. The catheter then delivers an
 implantable, soft polymer, called a "matrix," which remains within the
 prepared section of the tube. The matrix is smaller than a grain of rice.
 The procedure is then repeated on the other fallopian tube. Healthy tissue
 will grow into the matrix, creating a complete blockage of each tube. A
 confirmatory dye test called a hysterosalpingogram (HSG) is conducted at
 three months post-procedure to ensure the fallopian tubes are completely
 blocked and that the woman can begin relying on Adiana for permanent
