Opinion

MEMORANDUM AND ORDER

ANITA B. BRODY, District Judge.

I. Introduction

On August 7, 2008, Plaintiff EUSA Pharma (US), Inc., (“EUSA”) brought an action against Defendants Innocoll Pharmaceuticals Limited and Innocoll Technologies Limited (collectively “Innocoll”) for declaratory and injunctive relief. EUSA requested a preliminary injunction to prevent Innocoll from beginning a clinical trial that might trigger EUSA’s option to purchase the exclusive license to commercialize a product being developed by Innocoll. On August 11, 2008,1 entered a temporary restraining order preventing the option’s expiration that remains in effect (Doc. # 11). On October 2 and 3, 2008, I conducted an evidentiary hearing, and on December 19, 2008, I heard oral argument. Considering the record and pleadings, I will issue the preliminary injunction requested by EUSA.

II. Findings op Fact

EUSA and Innocoll are pharmaceutical companies. (Hr’g Tr. 5, 149, Oct. 2, 2008 [hereinafter “10/2 Hr’g Tr.”].) EUSA specializes in pain control and cancer management drugs. (10/2 Hr’g Tr. 5.) Innocoll specializes in pharmaceutical products that utilize collagen. (10/2 Hr’g Tr. 149.) This case concerns the CollaRx® Bupivacaine Implant (“B-Implant”) being developed by Innocoll. EUSA currently has an option to buy the exclusive license to commercialize the B-Implant in the United States. (PL’s Ex. 8.) Before it can be commercially profitable, however, the U.S. Food and Drug Administration (“FDA”) must approve the B-Implant for use in the U.S. (10/2 Hr’g Tr. 9.)

A. The FDA Approval Process

For a drug to receive FDA approval, the company requesting approval (called a “sponsor”) must conduct clinical trials to establish safely and efficacy, (see 10/2 Hr’g Tr. 81-84.) Once clinical trials are complete, the sponsor submits to the FDA a New Drug Application (“NDA”) with supporting clinical data. (10/2 Hr’g Tr. 83.) The FDA decides whether to grant approval based on this NDA. (10/2 Hr’g Tr. 83-84.) Thus, the process of developing a drug for the U.S. focuses on putting together a strong NDA with compelling clinical data.

Federal regulations govern how a sponsor may conduct clinical trials. See 21 C.F.R. §§ 312.1 et seq. Before a sponsor may begin a clinical trial on human subjects, two requirements must be satisfied. (10/2 Hr’g Tr. 81.) First, the sponsor must submit to the FDA an Investigational New Drug Application (“IND”). 21 C.F.R. § 312.20(a). Second, an Investiga-tional Review Board must approve the trial after reviewing its protocol and past clinical trials on animals. (10/2 Hr’g Tr. 81.)

With regard to the clinical trial process, “[t]he clinical investigation of a previously untested drug is generally divided into three phases. Athough in general the phases are conducted sequentially, they may overlap.” 21 C.F.R. § 312.21. A *574 Phase I clinical trial involves few patients (usually from 10 to 20) and primarily measures safety. (10/2 Hr’g Tr. 81-82.) A Phase II clinical trial involves more patients (usually from 100 to 200) and primarily measures efficacy. 1 (10/2 Hr’g Tr. 82.) Specifically, a Phase II trial measures how patients respond to a drug at various doses for a given indication (i.e., circumstance in which the drug may be used for treatment). (10/2 Hr’g Tr. 36-37.) In this way, the sponsor tries to determine as closely as possible the optimal dose 2 or range of doses for that indication. 3 Id. A Phase III clinical trial involves many more patients (usually up to several thousand) and aims to produce compelling clinical data for the NDA. (10/2 Hr’g Tr. 36-37, 83.) In Phase III, the sponsor gives enough patients the optimal dose or range of doses determined from Phase II data to establish a high likelihood that the drug will be safe and effective when prescribed by doctors. 4 (10/2 Hr’g Tr. 37, 83.)

During this process, a sponsor may request three types of meetings with the FDA. (10/2 Hr’g Tr. 83.) A “Type A” meeting may be requested when a dispute arises between the sponsor and the FDA. (10/2 Hr’g Tr. 85.) A “Type B” meeting may be requested after Phase II to seek guidance from the FDA on how best to proceed with Phase III. Id. Sponsors normally request Type B meetings before designing a Phase III trial. Id. A “Type C” meeting is neither Type A nor B and can be requested at any time. (10/2 Hr’g Tr. 85-86.)

No drug being developed has a 100 percent chance of getting FDA approval and becoming commercially available. (10/2 Hr’g Tr. 27.) According to accepted wisdom in the pharmaceutical industry, however, drugs have an increasingly higher chance of success after each phase of clinical trials. (10/2 Hr’g Tr. 24, 26-27.) During the hearing in this case, a credible witness testified as follows: “[OJbviously in Phase I, the chance of making it are very low, five to ten percent.... In Phase II, then it’s tens of percent. And at the end of Phase III ... you might get up into the 50 to 70 percent.” (10/2 Hr’g Tr. 26.)

B. The B-Implant

The B-Implant is a novel innovation in post-surgical pain relief. (10/2 Hr’g Tr. 50-53, 152.) It is a collagen 5 sponge impregnated with bupivacaine hydrochloride, a known anesthetic, that a doctor implants inside a patient to provide local anesthesia after surgery. (10/2 Hr’g Tr. 13-14, 150- *575 151.) Once the sponge delivers the medicine, the collagen degrades and becomes indistinguishable from human collagen already inside the body. (10/2 Hr’g Tr. 150.) If the B-Implant becomes commercially available, it could reduce the need for doctors to prescribe opiates such as morphine and OxyContin for post-surgical pain relief. (10/2 Hr’g Tr. 152.)

In a Phase I trial, Innoeoll administered the B-Implant to 12 patients who had each undergone a hysterectomy. (10/2 Hr’g Tr. 82.) On February 28, 2007, Innoeoll submitted to the FDA an IND for Phase II clinical trials on post-hysterectomy and other post-surgery patients. (Pl.’s Ex. 14.) The document indicates that Phase III trials would occur only after Phase II was completed. 6 (Pl.’s Ex. 14 §§ 4.1.3, 4.1.4.2, 4.1.5.) Currently, Phase II trials for the B-Implant are ongoing. (10/2 Hr’g Tr. 95.)

C. The Parties’Negotiations

In Spring 2007, Bryan Morton (“Morton”), the chief executive officer of EUSA and of EUSA Pharma (Europe) Limited (“EUSA/Europe”), had a meeting with Dr. Michael Myers (“Myers”), the chief executive officer of Innoeoll. (10/2 Hr’g Tr.
