  Item 8.01 Other Events.
  On June 28, 2007, Cytokinetics, Incorporated (the Company) issued two press releases announcing the results of four Phase II clinical trials of ispinesib. Ispinesib is a novel small molecule inhibitor of kinesin spindle protein (KSP), a mitotic kinesin essential for proper cell division. Ispinesib has arisen from a broad strategic collaboration between the Company and GlaxoSmithKline (GSK), to discover, develop and commercialize novel small molecule therapeutics targeting human mitotic kinesins for applications in the treatment of cancer and other diseases.
  The first press release announced the final results from a multicenter Phase II clinical trial sponsored by GSK, which evaluated ispinesib in patients with locally advanced or metastatic breast cancer.
  The second press release announced the results from three Phase II clinical trials of ispinesib administered as monotherapy, one in patients with hepatocellular cancer, one in patients with melanoma, and one in patients with hormone-refractory prostate cancer. All three clinical trials were sponsored by the National Cancer Institute.
  Copies of the press releases are being filed as Exhibit 99.1 and Exhibit 99.2 to this Current Report on Form 8-K, and are hereby incorporated by reference into this Item 8.01.
