December 16, 2011

IN RE: YASMIN AND YAZ (DROSPIRENONE) MARKETING, SALES PMF PRACTICES AND PRODUCTS LIABILITY LITIGATION
THIS DOCUMENT RELATES TO: JILL FENDER, AS SPECIAL ADMINISTRATOR AND SURVIVING PARENT OF THE ESTATE OF MELISSA A. FENDER, DECEASED
v.
BAYER HEALTHCARE PHARMACEUTICALS, ET AL.



The opinion of the court was delivered by: David R. Herndon Chief Judge United States District Court

MEMORANDUMUM AND ORDER

Regarding That part of the Motion which seeks to Exclude Testimony of Plaintiffs' Expert Witnesses David Green, M.D., Ph.D. and Mitchell Botney, M.D. (Partial Ruling on Document No. 47)

I. INTRODUCTION

Defendants Bayer HealthCare Pharmaceuticals Inc. and Bayer Pharma AG ("Bayer") move, in part, to exclude the testimony David Green, M.D., Ph.D. and Mitchell Botney, M.D. as part of plaintiff's evidence. (Doc. 47).*fn1 Familiarity with the underlying proceeding is presumed. For the reasons that follow, Bayer's motion is DENIED on all grounds raised.

II. BACKGROUND

This Order is part of the Court's consideration of one of the bellwether cases in a multidistrict litigation (MDL) action relating to the manufacture, marketing, and sale of the prescription pharmaceuticals known as YAZ and Yasmin.*fn2 Jill Fender, as Special Administrator and Surviving Parent of the Estate of Melissa A. Fender, Deceased v. Bayer Healthcare Pharmaceuticals, et al. Case No. 09-CV-20036-DRH.

YAZ and Yasmin, are manufactured, marketed, and sold by Bayer, and are members of a class of prescription medicines known as combined hormonal oral contraceptives ("COCs"), which contain both an estrogen and a progestin component (Doc. 2090 p. 6). The vast majority of COC's, including YAZ and Yasmin, contain the same type of estrogen--ethinyl estradiol (EE). Id.*fn3 In contrast to estrogen, the progestins in COCs are of many types. The progestin in YAZ and Yasmin is a newer type of progestin known as drospirenone ("DRSP"). Id.

DRSP-containing COCs are known as "fourth-generation" COCs (classified by the type of progestin used). Id. at pp. 6-5. COCs containing earlier developed progestins are categorized as "first-generation," "second-generation," and "third-generation." Id. at p. 6. First-generation COCs contain the progestin norethynodrel. Id. Second-generation COCs contain the progestin Levonorgestrel ("LNG") and third-generation COCs contain several progestins, including desogestrel, gestodene, and norgestimate ("NGM"). Id.

It is generally accepted that there is an increased risk of venous thromboembolic (VTE) disease (disease relating to blood clotting in the veins) in COC users (Doc. 2102-14 p. 5; Doc. 2090-2 p. 2). It is also generally accepted that second-generation COCs (LNG-containing COCs) are considered to have a low risk for VTE disease (Doc. 2102-14 p. 6). Because the VTE risk associated with second-generation COCs is relatively low, LNG-containing COCs are often selected as a reference treatment in comparative studies evaluating whether there is an association between third-generation COCs and an increased risk of VTE disease (See e.g., Doc. 2102-4) and in comparative studies evaluating whether there is an association between DRSP-containing COCs and an increased risk of VTE disease (See e.g., Doc. 2102-14 pp. 5-6). In the mid-1990s, various reports indicated that users of third-generation COCs were at higher risk of VTE disease than users of second-generation COCs (Doc. 2090-2 p. 2).*fn4

At issue in this litigation is the safety of DRSP-containing COCs and whether the use of DRSP is associated with a higher risk of VTE disease. Specifically, plaintiffs contend that Bayer misrepresented or omitted facts pertaining to the safety and efficacy of YAZ and Yasmin. With respect to the safety of YAZ and Yasmin, plaintiffs contend that the DRSP component of the drugs is associated with an increased risk of VTE disease and of potentially life-threating thrombosis complications, including deep vein thrombosis (DVT) (a blood clot formation in one of the body's deep veins) and pulmonary embolism ("PE") (a clot formation that travels to the lungs).*fn5

In this bellwether case, the plaintiff, Jill Fender, alleges that her daughter, Melissa A. Fender, suffered a fatal PE in July of 2007, as a result of taking YAZ for a period of approximately seven months. Melissa Fender was prescribed YAZ by a nurse practitioner after suffering break-through bleeding and diagnosis of ovarian cysts while taking other COCs. Before her death in July of 2007, Melissa Fender had taken other oral contraception medicines without experiencing any symptoms of PE. Melissa fender, shortly after a long road trip to and from New Jersey to her home in Iowa, experienced intermittent shortness of breath and chest pain. She was evaluated for these symptoms on July 21, 2007 and then collapsed during a walk on July 27, 2007, and was pronounced dead a short time later. The coroner later determined the cause of death was a PE. Plaintiff's experts, Dr. Green, and Dr. Botney, have each prepared reports with respect to the death of Melissa Fender (See Botney Report at Doc. 51, Ex.1 and Green Report at Doc. 51, Ex. 8). Based upon deposition testimony and their reports, Bayer seeks to exclude their testimony as experts. In particular, Bayer objects to each expert's opinion testimony that Melissa Fender's use of YAZ was a substantial factor in causing her fatal PE, and that if she had been using a different COC she would not have suffered the PE. In addition, Bayer seeks to exclude Dr. Botney's testimony that Melissa Fender experienced pain and suffering.

III. Legal Standard

FEDERAL RULE OF EVIDENCE 702, and Daubert, govern the admissibility of expert testimony. The Daubert standard applies to all expert testimony, whether based on scientific competence or other specialized or technical expertise. Smith v. Ford Motor Co., 215 F.3d 713, 719 (7th Cir. 2000) (citing Kumho Tire Co., Ltd. v. Carmichael, 526 U.S.137, 141 (1999)). Rule 702 provides: If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise, if (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.

Fed. R. Evid. 702. Daubert clarified that Rule 702 charges the district court with the task of ensuring that expert testimony is both relevant and reliable. Daubert, 509 U.S. at 589. This is commonly referred to as the "gatekeeper" role of the court. See, e.g. Banister v. Burton, 636 F.3d 828, 831 (7th Cir. 2011)(where the court stated that "it is the district court's role to act as gatekeeper before admitting expert scientific testimony in ...
