Item 7.01. | Regulation FD Disclosure. |
As previously disclosed, Medivation, Inc. has recently concluded that the mechanism of action of MDV9300 (pidilizumab) is not as an inhibitor of PD-1, and work is underway to determine the mechanism of action. Under its investigational new drug application (IND) for MDV9300, Medivation has advised the U.S. Food and Drug Administration (FDA) of this conclusion, and the FDA has placed the IND on partial clinical hold and requested Medivation to revise relevant statements in the related investigator brochure, protocols and informed consent documents. Medivation may not enroll patients into its Phase 2 clinical trial evaluating the safety and efficacy of MDV9300 in patients with relapsed or refractory diffuse large B-cell lymphoma until such statements are revised and the partial clinical hold is removed. Although the Phase 2 clinical trial was initiated in December 2015, no patients have been enrolled to date. Medivation believes the partial clinical hold does not relate to concerns regarding the safety of MDV9300. Medivation plans to submit the requested documents in February 2016. The FDA has 30 days thereafter to notify Medivation if clinical studies with MDV9300 may be resumed. Under the partial clinical hold, patients who are currently receiving MDV9300 through investigator-sponsored trials of MDV9300 that cross-reference Medivations IND may continue on treatment, but Medivation must inform investigators to update protocols and informed consent documents to state that MDV9300 is not an anti-PD-1 antibody.
In addition, Medivation intends to submit an amendment to the Chemistry, Manufacturing and Controls (CMC) section of its IND for MDV9300 to address certain manufacturing changes. Medivation plans to submit the CMC amendment in the first half of 2016 and intends that patients in its Phase 2 clinical trial will be treated with MDV9300 manufactured in accordance with the amended IND.
The Company has furnished an updated corporate presentation as Exhibit 99.1 to this Form 8-K.

Safe Harbor This presentation includes forward-looking statements concerning our business plans and prospects that are made pursuant to the safe harbor provisions of the federal securities laws. Forward-looking statements are any statements regarding future events or results, and may be identified by the use of words such as “anticipate,” “expect,” “may,” “potentially,” “projected”, “target” and similar words. Forward-looking statements involve risks and uncertainties that could cause Medivation's actual operations and results to differ significantly from those discussed herein, including, without limitation, risks related to: the inherent uncertainty associated with pharmaceutical product development and clinical trials; the timing of our clinical trials, including difficulties or delays in initiating any of the trials planned for 2016, completing the enrollment of ongoing trials or manufacturing or supplying product for our clinical trials; the timing and sufficiency of the data generated from completed, ongoing or planned clinical trials to support approval of our product candidates or expand the label for XTANDI® (enzalutamide); earlier pre-clinical and clinical results may not be reproduced or confirmed in subsequent pivotal or controlled trials; the process of obtaining regulatory approval is uncertain, and may not be completed or may be unsuccessful; discovery of new safety information which may cause us to re-evaluate our development programs; our ability to effectively and successfully commercialize our product candidates if or when approved by regulatory agencies, including our ability to obtain competitive pricing and reimbursement coverage; our dependence on our collaboration relationship with Astellas to fund the continued development, manufacturing and commercialization of XTANDI and the revenue generated from such collaboration to fund our other clinical development programs; the introduction of generic competition or challenges to our intellectual property portfolio which may result in the loss of intellectual property protection and our competitive advantage; our past financial or operating performance may not be indicative of future performance or results; unanticipated expenditures or liabilities; and other risks detailed in Medivation's filings with the Securities and Exchange Commission, or SEC, including our quarterly report on Form 10-Q for the quarter ended September 30, 2015, which was filed on November 6, 2015. You are cautioned not to place undue reliance on the forward-looking statements, which speak only as of the date of this presentation. Medivation disclaims any obligation or undertaking to update, supplement or revise any forward-looking statements contained in this presentation. This presentation includes non-GAAP financial measures, and a reconciliation between the non-GAAP and GAAP financial measures is available on Medivation’s website at www.medivation.com within the investor relations section. Management believes this non-GAAP financial information is useful for management and investors, when considered in conjunction with Medivation’s GAAP financial statements, because management uses such information internally for its operating, budgeting and financial planning purposes. Non-GAAP financial information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of Medivation’s operating results as reported under U.S. GAAP.

Talazoparib (MDV3800) Opportunity
Cancers have frequent errors in DNA repair and often struggle to replicate their DNA Cancers that cannot repair and replicate their DNA will die PARP is a major DNA repair pathway; Inhibiting PARP can push CAs “over the edge” Because cancers have more DNA repair defects than normal cells, PARP inhibitors may be more toxic to cancer cells than normal cells Talazoparib opportunity falls into 2 broad categories: Cancers whose DNA is compromised by DNA repair mutations like BRCA1/2 or homologous recombination deficiencies (HRD) Cancers whose DNA can be nicked by DNA-damaging therapies like alkylation chemotherapy or radiation to create sites for PARP trapping Combining talazoparib with chemotherapy or radiation leverages talazoparib’s superior PARP trapping and is a larger opportunity than HRD monotherapy Anti-Tumor Mechanism Behind PARP Inhibition
