Cardium Initiates Phase 3 AWARE Clinical Study


May 16, 2007 -- Cardium Therapeutics (OTCBB:CDTP) announced the start of patient recruitment for its Phase 3 clinical trial (AWARE) to evaluate the therapeutic effects of Cardium's lead product candidate, Generx™ (alferminogene tadenovec, Ad5FGF-4), in women for the potential treatment of myocardial ischemia. Myocardial ischemia, insufficient blood flow within the heart muscle, gives rise to angina associated with coronary heart disease. Generx represents a new therapeutic class of biologics designed to promote angiogenesis, a natural process of blood vessel growth within the heart muscle, following a one-time intracoronary administration from a standard cardiac infusion catheter.

The randomized, placebo-controlled, double-blind trial, which is called AWARE (Angiogenesis in Women with Angina pectoris who are not candidates for Revascularization), is expected to enroll approximately 300 women with recurrent stable angina pectoris who are not candidates for revascularization and who are receiving optimal drug therapy. The primary endpoint is the improvement in time to onset of electrocardiogram changes diagnostic of myocardial ischemia during exercise treadmill testing at six months following administration. The secondary endpoints are improvement in myocardial blood flow within the affected heart muscle measured by adenosine SPECT (single photon emission computed tomography) imaging, as well as improvements in other measures of angina. The AWARE study is expected to include up to 50 U.S. clinical centers. Enrollment criteria, participating sites and other information about the AWARE trial can be found here.

Cardium's therapeutic approach to the treatment of myocardial ischemia associated with coronary heart disease has been the focus of the most widely-conducted clinical studies for Angiogenic Gene Therapy (AGENT-1 through AGENT-4), which to date have involved 663 patients at more than one hundred U.S., European and other international medical centers. Generx represents the first and only DNA-based cardiovascular therapeutic to be advanced to Phase 3, and the Company believes it to be the only current Phase 3 product candidate for the potential treatment of patients with stable angina, a chronic medical condition affecting millions of patients in the U.S. and worldwide.

"Our just-initiated AWARE trial is an important and timely clinical study and represents a major milestone for Cardium. There is a growing awareness that cardiovascular disease in men and women may be somewhat different and while men have long been a focus with respect to heart disease, it is well-documented that women have been largely under-represented in cardiovascular clinical trials despite the fact that heart disease is now the leading cause of death among adult women in both the U.S. and Europe," stated Christopher J. Reinhard, Cardium's Chairman and Chief Executive Officer. "We are enthusiastic about our lead product candidate, Generx, which was previously shown to be associated with substantial improvement in myocardial blood flow, of a magnitude similar to that reported in the literature for patients following bypass surgery or angioplasty."

About Women and Heart Disease
An estimated 7.4 million American women are currently living with coronary heart disease and more than 4.6 million women suffer from angina. The American Heart Association reports that more women's lives are claimed annually by cardiovascular disease than by the next five leading causes of death combined (all cancers, chronic obstructive pulmonary disease (COPD), Alzheimer's, diabetes and accidents). Despite these stark statistics, surveys indicate that nearly half of women are not aware that heart disease is the leading cause of death among women, and only 20 percent identified heart disease as the greatest health problem facing women today. Observed differences between men and women with coronary heart disease are not fully understood. Some researchers believe the differences may be the result of microvascular disease, the narrowing or stiffening of the smaller arteries and arterioles that nourish the heart. While microvascular disease is believed to affect both men and women with coronary heart disease, the prevalence is apparently somewhat higher in women and in patients with diabetes.

About Generx
Generx™ (alferminogene tadenovec, Ad5FGF-4) is the lead product candidate in a new class of cardiovascular biologics that is being developed to leverage the body's natural healing processes in response to repeated ischemic stress (insufficient blood flow and myocardial oxygen supply due to coronary heart disease). The natural biologic response to repeated transient ischemia is angiogenesis, the growth of new collateral blood vessels, which is orchestrated by a complex and incompletely understood cascade involving many myocardial-derived growth factors. These newly-formed vessels can effectively augment blood flow and oxygen delivery to parts of the patient's heart downstream from a blockage in a coronary artery. In many patients however, including those with recurrent angina, coronary collateral vessel formation is insufficient to meet the heart's needs during stress. Currently available anti-anginal drugs, which may provide symptomatic relief, are generally designed to alter the oxygen demand of the heart muscle or dilate vessels to temporarily relieve angina. Generx is an angiogenic therapeutic that is designed to promote the heart's natural response of collateral growth and to increase blood flow in the microcirculation.

About Cardium
Cardium Therapeutics, Inc. and its subsidiaries, InnerCool Therapies, Inc. and the Tissue Repair Company, are medical technology companies primarily focused on the development, manufacture and sale of innovative therapeutic products and devices for cardiovascular, ischemic and related indications. Cardium's lead product candidate, Generx (alferminogene tadenovec, Ad5FGF-4), is a DNA-based growth factor therapeutic being developed for potential use by interventional cardiologists as a one-time treatment to promote and stimulate the growth of collateral circulation in the hearts of patients with ischemic conditions such as recurrent angina.

Cardium's InnerCool Therapies subsidiary is a San Diego-based medical technology company in the emerging field of temperature modulation therapy to rapidly and controllably cool the body in order to reduce cell death and damage following acute ischemic events such as cardiac arrest or stroke, and to potentially lessen or prevent associated injuries such as adverse neurological outcomes. For more information about Cardium's InnerCool subsidiary and therapeutic hypothermia, including InnerCool's Celsius Control System™, which has received regulatory clearance in the U.S., Europe and Australia, please visit www.innercool.com.

Cardium's Tissue Repair Company subsidiary (TRC) is a San Diego-based biopharmaceutical company focused on the development of growth factor therapeutics for the treatment of severe chronic diabetic wounds. TRC's lead product candidate, Excellarate, is a DNA-activated collagen gel for topical treatment formulated with an adenovector delivery carrier encoding human platelet-derived growth factor-BB (PDGF-BB). Excellarate is initially being developed to be administered once or twice for the potential treatment of non-healing diabetic foot ulcers. Other potential applications for TRC's Gene Activated Matrix™ (GAM) technology include therapeutic angiogenesis (cardiovascular ischemia, peripheral arterial disease) and orthopedic products, including hard tissue (bone) and soft tissue (ligament, tendon, cartilage) repair.
