On June 3, 2007. Pharmacyclics, Inc. a Delaware corporation (the "Registrant"), announced final results from an open-label multi-center Phase 2 clinical trial, which indicated that Xcytrin^® (motexafin gadolinium) Injection, may improve the efficacy of stereotactic radiosurgery by providing more accurate magnetic resonance imaging (MRI) treatment-planning and better defining the treatment field in patients with brain metastases from solid tumors. Xcytrin allowed physicians to identify occult brain metastases in 24% of patients that were missed with standard MRI contrast agents and were amenable to stereotactic radiosurgery. The data were presented at the 2007 American Society of Clinical Oncology Annual Meeting (ASCO) in Chicago.

The foregoing description is qualified in its entirety by reference to the Registrant's Press Release dated June 3, 2007, a copy of which is attached hereto as Exhibit 99.1 and incorporated herein by reference.
