Pharmacyclics is a pharmaceutical company developing novel agents to improve current therapeutic approaches to cancer, cardiovascular diseases, and inflammation. The company's proprietary products are derived from its core technology in biometallic chemistry. These products under development are based upon small molecules, which bind metals in a unique way and are capable of capturing and focusing forms of energy used in a variety of medical applications. The company has one product in registration with the FDA, Gadolite® Oral Suspension, a contrast agent for imaging the gastrointestinal tract; two products in clinical development, Gd-Tex (Motexafin gadolinium), a radiation sensitizer, Lu-Tex, a photosensitizer; and several compounds in preclinical development.

MRI Contrast Agents:

An oral suspension of synthetic crystalline aqueous orange-flavored MRI contrast agent to enhance delineation of the bowel. Gadolite contains gadolinium, a lanthanide metal with paramagnetic characteristics. The toxic Gd is bound to become inert, along with water, inside a zeolite crystalline lattice structure. Gadolite gives a bright signal, and provides improved definition of the gastrointestinal tract from adjacent tissues.
Pharmacyclics receives an approvable letter from the FDA for Gadolite® Oral Suspension and in the United Kingdom an European marketing agreement signed with E-Z-Em, Ltd. in Dec. 1996.
