MEMORANDUM OPINION
In this removed diversity products liability matter, plaintiff claims defendant’s hormone therapy product, Prempro, caused or aggravated her breast cancer. Because numerous suits of this nature were filed in many jurisdictions, the Judicial Panel on Multidistrict Litigation convened multidistrict litigation (“MDL”) proceedings in the Eastern District of Arkansas, and this matter was transferred to that district for participation in the MDL proceedings, including general discovery. See Torkie-Tork v. Wyeth, No. 1:4cv945 (E.D.Va. Nov. 1, 2004) (Conditional Transfer Order). At the conclusion of MDL proceedings, the matter was returned to this district for all further proceedings, including case-specific discovery, summary judgment, and if necessary, a trial. See Torkie-Tork v. Wyeth, MDL No. 1507 (E.D.Ark. Apr. 8, 2010) (Conditional Remand Order). After disposition of various summary judgmеnt motions, 1 two claims remained for trial: (i) the claim that Wyeth negligently failed to provide an adequate warning of the breast cancer risks associated with Prempro, and (ii) the claim that Wyeth negligently designed Prempro with respect to the risk of breast cancer.
Among the myriad motions filed prior to trial was Wyeth’s motion
in limine
to exclude any evidence concerning Wyeth’s “fail[ure] to test ... Prempro.” Def. Mot.
in Limine
No. 12. This motion was denied; although plaintiff apparently was not asserting a separate claim for negligent failure to conduct additional studies of Prempro, it was unclear prior to trial whether evidence relevant to this issue might also be relevant to plaintiffs negligent failure to warn claim. Yet in thе course of the trial, it became increasingly clear that plaintiffs counsel was eliciting testimony and presenting documents for the purpose of establishing and suggesting to the jury that Wyeth had negligently failed to conduct studies of Prempro, in addition to those required by the FDA, to assess more accurately any link between
I.
Plaintiff Georgia Torkie-Tork is a citizen of Virginia. Defendant Wyeth is a Delaware corporation with its principal place of business in New Jersey. During times relevant to this litigation, Wyeth was one of the world’s largest pharmaсeutical companies 3 and the maker of Prempro, a hormone replacement therapy drug approved by the Food and Drug Administration (“FDA”) for treatment of menopausal symptoms. Prempro is a combination hormone therapy drug consisting primarily of the hormones estrogen and progestin (“E+P”).
Beginning in or about 1996, plaintiff began experienсing severe menopausal symptoms. To address these symptoms, plaintiff obtained and filled prescriptions for Prempro from three physicians at various times, although the evidence is in dispute as to when she first began taking Prempro and the length of time for which she took it. Plaintiff claimed she began taking the drug sometime in 1998, but the pharmacy records produсed show prescriptions only as early as May 1999. In any event, the parties agree that she ceased using Prempro in June 2002. Thus, plaintiff contends she took Prempro continuously for four years, whereas Wyeth points out that pharmacy records show only about two and a half years of use. 4
The warning label for Prempro contained several statements regarding breast cancer, including the following:
The majority of studies ... have not shown [a breast cancer] association in women who have ever used estrogen replacement therapy. The effect of added progestins on the risk of breast cancer is unknown, although a moderately increased risk in taking combination estrogen/progestin therapy has been reported. Other studies have not shown this relationship.
See Wyeth I,
The use of Prempro proved effective for the treatment of plaintiffs symptoms, and she continued using the drug until June 2002, at which time an abnormality was noted on her mammogram.

At the direction of Dr. Ronald Orleans, plaintiffs
After plaintiff ceased taking Prempro, the Women’s Health Initiative (“WW”) released results from a large-scale clinical trial of hormone therapy drugs indicating a 1.24 relative risk of breast cancer for those taking Prempro. 9 After publication of the WHI results, sales of Prempro dropped dramatically. The trial recоrd reflects that Prempro continues to be sold, although with a new warning label. Wyeth’s consistent contention has been that prior to the WHI study’s release, scientific studies had been inconclusive regarding Prempro’s breast cancer risk. At trial, plaintiff has contended that instead of allowing the breast cancer association to remain inconclusivе until the WHI study was completed, Wyeth should have conducted further studies of Prempro on its own to ascertain the nature of the risk and to warn doctors accordingly. 10
II.
Analysis properly begins with the Supreme Court of Virginia’s clearly-expressed view that products liability actions may take one of three forms. In this respect, the Supreme Court of Virginia noted sрecifically in
Morgen Industries, Inc. v. Vaughan,
But this point does not alone suffice to dispose of the question whether under Virginia law Wyeth had a duly to conduct additional studies of Prempro beyond those required by the FDA such that its failure to do so amounted to a negligent failure to warn. This question is resolved by the Supreme Court’s further teaching in
Owens-Corning Fiberglas Corp. v. Watson,
Plaintiff seeks to avoid the plain meaning of the
Owens-Coming
opinion by arguing that the court’s рronouncements are mere dicta. This argument is unpersuasive. To be sure, the
Owens-Coming
teaching was issued in an odd procedural context. The trial record in
Owens-Coming
indicated that the trial court instructed the jury to apply a should have known standard, and because neither party objected, the instruction became the “became the law of [the] case.”
Id.
at 136,
In sum, there can be no serious doubt that the reason to know standard, as elucidated in the
Owens-Coming
opinion, applies here, Indeed, in the context of pharmaceutical drugs, as here, imposition of the reason to know standard is particularly sensible given the FDA already requires testing of any drug as a qualification for approval. Accordingly, evidence and testimony is not admissible for the purpose of establishing that Wyeth could have or should conducted additional tests of Prempro, and counsel must not be permittеd to advance arguments in this regard. The only dangers for which Wyeth had a duty to warn adequately are those dangers which Wyeth knew or had reason to know existed based on the science available at the time the product left Wyeth’s hands.
Owens-Corning,
The Clerk is directed to send a copy of this Memorandum Opinion to all counsel of record.
Notes
. At the summary judgment stage, plaintiff conceded that under Virginia law, summary judgment was appropriate for Wyeth on the claims for strict liability for failure to warn, strict liability for design defect, negligent misrepresentation, and breach of express warranty.

.Although not pertinent to the question addressed here, it is worth briefly noting developments in the case since the issuance of the bench ruling addressed here. Following completion of рlaintiffs case in chief, Wyeth was granted judgment as a matter of law on plaintiffs design defect claim pursuant to Rule 50(a), Fed.R.Civ.P.
See Torkie-Tork v. Wyeth,
No. 1:04cv945 (E.D.Va. Nov. 30, 2010) (Order). A ruling on Wyeth’s motion for judgment as a matter of law on plaintiffs punitive damages claim was initially deferred but ultimately granted at the conclusion of Wyeth's case in chief
See Torkie-Tork v. Wyeth,
No. 1:04cv945 (E.D.Va. Dec. 2, 2010) (Order). Additionally, at the conclusiоn of Wyeth's case in chief, plaintiff won judgment as a matter of law on Wyeth's claim for contributory negligence.

Jury deliberations commenced on December 2, 2010, and the following day, the jury returned a unanimous verdict in favor of Wyeth, ruling that plaintiff had not proven, by the greater weight of the evidence, "that the warnings Wyeth provided to her prescribing doctor(s) were inadequate."

Wyeth I,
in resolving summary judgment on plaintiff's fraud claims, addressed the accuracy of the Prempro warning label, concluding that no statement in the warning label was false in light of the existing science.
.A 1999 compression mammogram revealed a spot in plaintiffs left breast in the exact place where, in 2002, cancer was detected. Although the spot was not determined to be cancerous in 1999, plaintiff was advised to have annual mammograms thereafter. She did not thereafter undergo all annual mammograms prior to 2002, missing "one or two” mammograms because she claimed it was
. A relative risk of 1.24 means that, in general, women who take combination hormone therapy drugs like Prempro are 1.24 times as likely to be diagnosed with breast cancer as women who did not take such a drug. For example, if the general risk of breast cancer in a population is, as plaintiffs expert witness testified, 30 out of 1,000 — meaning that without anyone taking Prempro, one would expect 30 wоmen out of every 1,000 to develop breast cancer — then the introduction of Prempro would increase the risk to approximately 37 out of 1,000, Tr. 11/23/10 PM, at 190:23-191:1.
. It is worth noting that for purposes of winning FDA approval for Prempro, Wyeth conducted certain required studies. The FDA, in approving Prempro and its warning label in 1994, concluded that the drug was safe and effective for its intended use based on then-existing scientific studies. The jury was properly instructed that this finding by the FDA was not conclusive as to whether this warning was adequate.
See
Tr. 12/2/10, at 202:14-203:1;
see also Wyeth v. Levine,
. The distinction between the two standards is clearly seen in other jurisdictions. For example, California recognizes both a strict liability failure to warn claim and a negligent failure to warn claim, with the critical distinction being that the negligence claim focuses on "what a reasonably prudent manufacturer would have known and warned about,” while the strict liability claim centers on what dangers were "known or knowable” in light of then-existing science.
