Spine Wave Notifies Protein Polymer Technologies of FDA Approval to Conduct U.S. Clinical Trials

Patient Enrollment for NuCore™ Injectable Nucleus IDE Clinical Trial Begins

SAN DIEGO, CA -- (MARKET WIRE) -- February 21, 2006 -- Protein Polymer Technologies, Inc. (OTC BB: PPTI) today announced that it has been notified by Spine Wave, Inc., that approval for an Investigational Device Exemption has been received from the U.S. Food and Drug Administration (FDA). This allows Spine Wave to conduct a pilot human clinical trial to investigate the safety and effectiveness of the company's NuCore™ Injectable Nucleus.

NuCore™ Injectable Nucleus, based on PPTI's patented tissue adhesive technology, is an injectable protein polymer formulation for repair of spinal discs damaged as a result of injury or aging. Injected in a liquid form, the NuCore material rapidly cures to a gel that has physical properties which mimic those of the natural nucleus. The companies are engaged in a program to develop and commercialize PPTI's technology for certain spinal and orthopedic applications. PPTI manufactures the NuCore material for Spine Wave's clinical trials.

"The FDA's approval to conduct clinical trials of NuCore™ Injectable Nucleus in the U.S. is a true affirmation of our core technology," said William N. Plamondon III, Chief Executive Officer of PPTI. "There is an unmet medical need for improved treatment options of low back pain. We believe this new technology provides surgeons a minimally invasive option for treating patients who suffer from back pain caused by damaged or degenerated discs."

NuCore™ Injectable Nucleus offers the potential to intervene early in the disc degeneration process and provide relief from chronic low back pain. Avoiding spinal fusion as a last resort treatment for disc degeneration disease would be of tremendous benefit to patients, since fusion destroys the natural function and mobility of the spine.

Back pain is the leading cause for healthcare expenditures in the United States. According to the American Academy of Orthopaedic Surgeons, treatment for back pain costs an estimated $100 billion a year in medical costs, lost working days and workers compensation. More than 31 million Americans wrestle with bouts of low back pain at any given time. One third of all Americans over the age of 18 had a back problem in the past five years severe enough for them to seek medical treatment.

Spine Wave has enrolled patients in microdiscectomy studies of NuCore Injectable Nucleus in four countries: Switzerland, Australia, Germany and the United States, and expects to expand enrollment of this and other studies in the first half of 2006.
