Hollis-Eden Pharmaceuticals Reports on Progress in Drug Development Programs; Announces Second Quarter 2008 Financial Results

Hollis-Eden Pharmaceuticals, Inc. (NASDAQ:HEPH), the world leader in the development of a new class of small molecule compounds based on endogenous steroid hormones, today reported on the Company's progress in its drug development programs in the areas of metabolic disorders, inflammatory conditions and cancer, and announced financial results for the second quarter of 2008.

Recent Progress in Drug Development Programs

During the second quarter of 2008, Hollis-Eden continued to advance its clinical development programs, with clinical trials now underway in four indications with its lead drug candidates - TRIOLEX(TM) (HE3286), in a Phase II clinical trial for type 2 diabetes and in Phase I/II clinical trials for ulcerative colitis and rheumatoid arthritis, and APOPTONE(TM) (HE3235), in a Phase I/II clinical trial for prostate cancer. Hollis-Eden believes TRIOLEX is a potential first-in-class insulin sensitizer and anti-inflammatory without immune suppression or bone loss, and that APOPTONE is a potential first-in-class apoptosis drug for cancer.

Metabolic Disorders: Type 2 Diabetes

In June 2008, Hollis-Eden reported positive interim data from its ongoing Phase I/II clinical trial with its investigational oral drug candidate TRIOLEX (HE3286) in obese insulin resistant subjects, supporting the potential benefit of an anti-inflammatory approach to improving insulin sensitivity in patients with type 2 diabetes. Leading academic researchers have linked inflammation and type 2 diabetes, and the role of inflammation in promoting insulin resistance and type 2 diabetes is well described in the scientific literature. The data, presented at a corporate symposium held in conjunction with the 68th Scientific Sessions of the American Diabetes Association, demonstrated that TRIOLEX is safe and well tolerated to date, and that it significantly improved insulin sensitivity and significantly lowered fasting blood glucose, insulin and triglyceride levels in obese insulin resistant subjects treated orally with the compound for 28 days when compared to placebo-treated subjects. These effects were accompanied by significant decreases in circulating and cellular inflammatory mediators.

The Company initiated a Phase II clinical trial with TRIOLEX in type 2 diabetes patients in mid-July. This Phase II, double-blinded placebo controlled 12-week dosing trial will enroll patients who are stable on metformin treatment only, the current first-line therapy for type 2 diabetes, with a hemoglobin A1c (HbA1c) level in excess of 7.5 percent. The primary endpoints for the trial will be safety and a reduction in HbA1c. Hollis-Eden plans to release preliminary data from this clinical trial in the fourth quarter of 2008, and plans to complete enrollment in the trial by the end of the year.

Hollis-Eden believes that the mechanism of action for TRIOLEX involves regulation of inflammation and reduced activation of NF-kappaB. NF-kappaB is a transcription factor that controls many of the genes involved in the inflammatory signaling pathway, including TNF-alpha, IL-1beta and IL-6. TRIOLEX also appears to act independently of the PPAR-gamma nuclear receptor and thereby may avoid the side effects associated with the current glitazone class of insulin sensitizing agents, such as Avandia(R) and Actos(R), which work through the PPAR-gamma pathway. Side effects reported to date with the glitazone class of drugs include weight gain, edema and increased cardiovascular events.

Inflammatory Diseases: Ulcerative Colitis and Rheumatoid Arthritis

Hollis-Eden is currently enrolling patients in a Phase I/II clinical trial with TRIOLEX in ulcerative colitis (UC). This Phase I/II oral dose ranging study will evaluate the safety, tolerance, pharmacokinetics and activity of TRIOLEX when administered orally for 28 days in patients with active, mild-to-moderate UC.

Hollis-Eden also has initiated a Phase I/II clinical trial with TRIOLEX for the treatment of rheumatoid arthritis (RA). The 28-day oral dose ranging study, which opened for enrollment this week, will assess safety and pharmacokinetics in stable RA patients on methotrexate, a commonly used RA treatment. The Company believes that certain aspects of the pathology driving UC and RA are similar. Therefore, data obtained in this UC study could potentially help support the design of the Company's clinical development program for RA, and could help accelerate the development of TRIOLEX for potential use in patients with acute inflammatory conditions.

Hollis-Eden previously reported that oral treatment with TRIOLEX provided benefit in several preclinical models of autoimmune diseases, including rheumatoid arthritis, multiple sclerosis and systemic lupus erythematosus and that benefit was associated with an expansion of regulatory T cells. Ongoing pre-clinical studies are aimed at new indications and at elucidating the role of regulatory T cells in TRIOLEX's mechanism of action. Hollis-Eden plans to present data from its ongoing clinical and preclinical studies at the 6th International Congress on Autoimmunity, to be held at Porto, Portugal September 10th to the 14th, where the Company has been invited to present in an oral session.

Inflammatory Diseases: Cystic Fibrosis

Cystic Fibrosis Foundation Therapeutics (CFFT), the non-profit drug discovery and development arm of the Cystic Fibrosis Foundation, selected TRIOLEX in late 2007 as a drug candidate for lung inflammation associated with cystic fibrosis. Hollis-Eden is currently in discussions with CFFT about the design of a possible Phase II study with TRIOLEX in cystic fibrosis. If Hollis-Eden and CFFT agree on the economics, clinical plan and an initial protocol, the Company will submit a separate investigational new drug application (IND) for TRIOLEX with the U.S. Food and Drug Administration (FDA) to gain clearance to initiate a clinical trial in CF. The Company believes that successfully developing a compound for cystic fibrosis could lead to opportunities relative to other pulmonary indications, such as COPD and asthma, with TRIOLEX.

Oncology: Prostate Cancer

Hollis-Eden has commenced a Phase I/II clinical trial with its oral drug candidate APOPTONE(TM) (HE3235) in late-stage prostate cancer patients who have failed hormone therapy and at least one round of chemotherapy treatment.

The Phase I/II open-label dose ranging study, being conducted with the Prostate Cancer Clinical Trial Consortium (PCCTC), will evaluate the safety, tolerance, pharmacokinetics and potential activity of APOPTONE when administered twice daily in late-stage prostate cancer patients. Based on safety findings after the initial 28-day cycle, patients will be eligible for additional cycles of treatment. Potential activity of the compound will be measured by standard prostate-specific antigen (PSA) tests and effect on well-established markers of progression free survival (PFS). In addition, in conjunction with Memorial Sloan-Kettering Cancer Center, the clinical trial will evaluate circulating tumor cell (CTC) enumeration as a marker for effectiveness for tumor treatment. Previous studies have shown that metastatic prostate cancer patients with less than 5 CTCs per 7.5 ml of blood have statistically better survival than patients with greater than 5 CTCs.

APOPTONE has been tested in a number of preclinical cancer models and has been shown to date to be active in controlling the incidence, growth and development of new tumors in these models. Hollis-Eden believes that APOPTONE may be directly inducing apoptosis, or cell death, in tumor cells, as opposed to traditional hormone blockade therapies directed at simply interrupting either the synthesis or the signaling of the tumor cell growth through the androgen or estrogen receptor. While hormone blockade therapy can effectively control prostate cancer for a period of time, it will eventually fail and the cancer can continue to grow and spread. Analysis of gene expression from tumor cells in preclinical studies conducted to date indicate APOPTONE appears to act as an apoptotic agent, down-regulating genes that protect tumor cells from apoptosis, such as Bcl-2, while increasing the expression of pro-apoptotic genes such as caspases.

"At mid-year 2008, Hollis-Eden has made significant progress in advancing our clinical development programs in four indications with our lead compounds, TRIOLEX and APOPTONE, and we believe we are well-positioned to potentially further demonstrate in multiple clinical trials their safety and activity in major market indications," stated Richard B. Hollis, Chairman and CEO of Hollis-Eden. "This progress represents a significant milestone in our quest to translate the therapeutic potential of our Hormonal Signaling Technology Platform into beneficial pharmaceuticals for the treatment of metabolic and autoimmune disorders, cancer, and other diseases associated with the process of aging. The opportunity to potentially deliver a new class of compounds that could restore fundamental biochemical signals lost to disease and aging is rare in our industry, and we are passionately focused today on converting our technology into commercial products.

"By year-end, our goal is to report preliminary clinical data from our Phase II trial in type 2 diabetes and from our Phase I/II trials in ulcerative colitis, rheumatoid arthritis and prostate cancer. Establishing clinical 'proof of concept' with our compounds in one of these indications could present the opportunity to leverage our technology platform for multiple additional clinical applications with large market opportunities. Given their safety profile and the positive data generated in clinical and preclinical trials to date, we believe our proprietary class of compounds hold the potential of yielding 'first-in-class' pharmaceuticals that could offer potential advantages over currently marketed therapies, and play a significant role in major disease markets in the United States and globally. So today we believe we are strategically positioned to potentially convert our technology into substantial shareholder value and to establish ourselves as a major factor in our industry."

Second Quarter 2008 Financial Results

For the quarter ended June 30, 2008, the Company reported a net loss of $6.0 million (or $0.21 per share), compared to a net loss of $5.8 million (or $0.20 per share) in the second quarter of 2007. For the six months ended June 30, 2008, Hollis-Eden reported a net loss of $11.7 million (or $0.40 per share), compared to a net loss of $12.3 million (or $0.42 per share) in the first six months of 2007. Included in the net loss for the second quarter and first half of 2008 was $0.7 million and $1.2 million, respectively, of stock-based compensation expense related to the adoption of SFAS No. 123R, compared to $0.6 million and $1.6 million in the same periods last year.

Research and development expenses were $4.4 million and $8.8 million for the quarter and six-month periods ended June 30, 2008, respectively, compared to $4.6 million and $9.2 million for the same periods in 2007. Research and development expenses decreased in 2008 compared to 2007 mainly due to the discontinuation of the Company's NEUMUNE(TM) (HE2100) research and development program and a decrease in stock option compensation expenses.

General and administrative expenses were $1.8 million and $3.6 million for the three-month and six-month periods ended June 30, 2008, respectively, compared to $1.9 million and $4.5 million for the same periods in 2007. General and administrative expenses decreased primarily as a result of reduced costs related to salaries, consulting, audit fees and stock option compensation expense.

Other income and expenses were $0.3 million and $0.7 million for the three-month and six-month periods ended June 30, 2008, respectively, compared to $0.7 million and $1.5 million for the same periods in 2007. The decrease in interest income was due to lower cash balances and interest rates.

As of June 30, 2008, the Company reported $34.1 million in cash and cash equivalents. Cash used in operations for the second quarter of 2008 totaled $4.8 million versus $6.3 million for the second quarter of 2007. Year to date in 2008, cash used in operations totaled $9.0 million, compared to $14.8 million in the first half of 2007.
