EpiCept Releases New Ceplene AML Data Demonstrating Leukemia Free Survival as Predictor of Improved Overall Survival

Data Presented at European Hematology Association's 13th Congress

TARRYTOWN, N.Y.--(HSMN NewsFeed)--Regulatory News: EpiCept Corporation (Nasdaq and OMX Nordic Exchange: EPCT) released new data that confirm that leukemia-free survival (LFS) is a valid surrogate endpoint for overall survival (OS) in Acute Myeloid Leukemia (AML) patients in complete remission. These findings are based on an analysis of data from the Phase III trial of Ceplene, EpiCept’s product candidate for the remission maintenance and prevention of relapse in patients with AML in first remission. This data is being presented at the European Hematology Association’s (EHA) 13th Congress in Copenhagen, Denmark.

“We believe the strong association between LFS and OS demonstrated in this study as well as the correlation between the treatment effect of Ceplene in combination with low-dose IL-2 on both LFS and OS provide further compelling evidence of the clinical benefits of Ceplene for AML patients,” remarked Jack Talley, president and CEO of EpiCept. “We have provided this data to regulators in Europe as part of our re-examination proceedings for the Ceplene Marketing authorization Application and believe it provides additional support for our request for a marketing authorization for this important product.”

The poster presentation entitled “Leukemia-free Survival (LFS) as a Surrogate for Overall Survival (OS) in AML Patients in Remission: A Trial of a Novel Immunotherapy with Histamine Dihydrochloride Plus Low-dose IL-2 (HDC/IL2),” will be presented by Dr. Marc Buyse Ph.D., a leading European cancer statistician. The data were derived from the pivotal 320 patient, Phase III trial for Ceplene, which met its primary endpoint of increased LFS (p <0.01) among AML patients in their first remission.

While the extension of OS duration is a principal goal of all cancer therapies, LFS is likely to be a better endpoint by which to evaluate the effect of remission maintenance therapies for AML, as OS may be confounded by alternative salvage therapies and unrelated events. By performing a weighted linear regression analysis between estimates of LFS and OS at specific time points and between the estimated effects of Ceplene with IL-2 on LFS and OS, researchers found a high correlation between the country-specific Kaplan-Meier estimates of 24-month LFS and 36-month OS in both treated and untreated groups (R2 = 0.71; P=0.0002). Similar correlations were also found between 24-month LFS and 48-month and 60-month OS. In addition, country-specific hazard ratios demonstrated that the treatment effect of Ceplene with IL-2 on LFS and OS were found to be highly correlated (R2 = 0.84; P=0.004). These new data add to the evidence of the statistical robustness of the clinical data supporting the benefits of Ceplene in AML.

Additional Ceplene Study Results Presented

In a separate poster presentation given at EHA, EpiCept released new findings from the pivotal Phase III study of Ceplene demonstrating that AML patients maintained their quality of life while undergoing treatment with Ceplene in combination with low-dose IL-2. These data were presented by Dr. Mats Brune, M.D., a leading European hematologist and principal investigator for the Ceplene Phase III clinical trial in a presentation entitled “Quality of Life During Remission Maintenance Immunotherapy in Acute Myeloid Leukemia: A Prospective Assessment using EORTC QLQ-C30 in a Randomized Trial of Histamine Dihydrochloride Plus Low-dose Interleukin-2.”

In the study, researchers compared quality of life and the impact of treatment-related symptoms in AML patients in their first complete remission who received up to 18 months of post-consolidation immunotherapy with Ceplene in combination with low-dose IL-2. Findings were based on the more than 60% of AML patients in the trial who were in first remission, and who had completed the baseline assessment and at least one follow-up quality of life questionnaire. Researchers found that twice daily subcutaneous injections of Ceplene and IL-2 for up to 10 cycles throughout 18-months had no major impact on quality of life and that global health status was maintained from baseline to last evaluation both for patients treated with Ceplene and IL-2 and for untreated control patients. These findings support the safety profile of Ceplene as well as the suitability of the therapy for at home administration in patients in remission from AML.

About Ceplene

Ceplene is EpiCept's registration-stage compound for the treatment of AML. Ceplene is designed to protect lymphocytes responsible for immune-mediated destruction of residual leukemic cells. Laboratory research has demonstrated that Ceplene reduces formation of oxygen radicals from phagocytes, inhibiting NADPH oxidase and protecting IL-2-activated NK-cells and T-cells.

In March 2008, the European Committee for Medicinal Products for Human Use (CHMP), the scientific committee of the EMEA, issued a negative opinion regarding the Marketing Authorization for Ceplene. EpiCept has formally requested a re-examination of this opinion through the appeal process, which is expected to occur in the third quarter of 2008.

About Acute Myeloid Leukemia (AML)

AML is the most common type of leukemia in adults. There are approximately 40,000 AML patients in the EU, with 16,000 new cases occurring each year. Once diagnosed with AML, patients are typically treated with induction chemotherapy and consolidation therapy, with the majority achieving complete remission. However, about 75-80% of patients who achieve first remission will relapse, and the median time in remission before relapse is only 12 months with current treatments. Less than 5% of relapsed patients survive long term.

About EpiCept Corporation

EpiCept is focused on unmet needs in the treatment of cancer and pain. The Company’s broad portfolio of pharmaceutical product candidates includes several pain therapies in clinical development and a lead oncology compound for AML with demonstrated efficacy in a Phase III trial; a marketing authorization application for this compound recently received a negative opinion and is being re-examined in Europe. In addition, EpiCept’s ASAP technology, a proprietary live cell high-throughput caspase-3 screening technology, can efficiently identify new cancer drug candidates and molecular targets that selectively induce apoptosis in cancer cells. Two oncology drug candidates currently in clinical development that were discovered using this technology have also been shown to act as vascular disruption agents in a variety of solid tumors.
