Cyclacel Pharmaceuticals Reports Preclinical Seliciclib-Erlotinib Synergy Data at AACRBERKELEY HEIGHTS, N.J.--(HSMN NewsFeed)--Cyclacel Pharmaceuticals, Inc. (Nasdaq: CYCC ; Nasdaq: CYCCP ) announced today preclinical results from a combination study of seliciclib, an orally-available cyclin dependent kinase (CDK) inhibitor, with epidermal growth factor receptor (EGFR) inhibitor erlotinib (TarcevaŽ). The study demonstrated that the drugs act synergistically in suppressing tumor growth in models of non-small cell lung cancer (NSCLC). The data, presented as a poster (#4003) at the Annual Meeting of the American Association for Cancer Research (AACR) in Los Angeles, is part of the company's broad program to assess the potential of seliciclib. Currently, seliciclib is being evaluated in a Phase II randomized double-blinded clinical trial as a single agent in NSCLC.
Biomarker analysis showed a significant decrease in the levels of cyclin D1 in tumor cells treated by the combination of the two drugs while treatment with either drug alone had minimal effect on cyclin D1 levels. Overexpression of cyclin D1 is one of the most frequently found abnormalities in human cancers and is known to correlate with the early onset of cancer and risk of tumor progression and metastasis. In most cancer types, including lung, breast, colon and sarcoma, cyclin D1 overexpression results from induction by oncogenic signals, such as ErbB2 and Ras. The mechanism underlying the observed synergy remains to be elucidated.

About Cyclacel Pharmaceuticals, Inc.
Cyclacel is a biopharmaceutical company dedicated to the discovery, development and commercialization of novel, mechanism-targeted drugs to treat human cancers and other serious disorders. The Company is currently evaluating seliciclib (CYC202), an orally-available cyclin dependent kinase inhibitor, in Phase II clinical trials for the treatment of lung cancer. Sapacitabine (CYC682), an orally-available, cell cycle modulating nucleoside analog, is in Phase I clinical trials for the treatment of solid and hematological cancers. CYC116, an orally-available, Aurora kinase and VEGFR2 inhibitor, is at the IND stage. Several additional programs are at an earlier stage.
Seliciclib is an orally-available cyclin dependent kinase (CDK) inhibitor that selectively inhibits multiple enzyme targets, CDK2/E, CDK2/A, CDK7 and CDK9, that are central to the process of cell division and cell cycle control. Seliciclib has been evaluated in approximately 250 patients, including patients with advanced NSCLC in which seliciclib was administered in combination with gemcitabine and cisplatin as first-line treatment and with docetaxel as second-line treatment. Seliciclib is currently being evaluated as a third-line treatment for Non-Small Cell Lung Cancer (NSCLC) in the Phase IIb, multi-center, randomized, double-blinded "APPRAISE" trial with the goal of generating a strong signal of activity in terms of Progression Free Survival. Cyclacel also intends to initiate a Phase II trial of seliciclib as a treatment for patients with nasopharyngeal cancer (NPC), a disease associated with Epstein-Barr Virus infection, in the second half of 2007.
