BERKELEY HEIGHTS, NJ – February 6, 2009 – Cyclacel Pharmaceuticals, Inc. (NASDAQ: CYCC, NASDAQ: CYCCP) announced today progress with a pivotal trial plan for sapacitabine, its oral nucleoside analogue, for the treatment of hematological malignancies. The announcement follows the company’s recent meeting with the U.S. Food and Drug Administration (FDA).

The pivotal trial plan consists of treating in an open-label, single arm study approximately 100 patients with acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS) on a dosing regimen to be selected from the currently ongoing randomized Phase 2 study of oral sapacitabine in elderly patients. The company anticipates that it will start enrolling patients in such a pivotal study within 2009. Efficacy and safety in a total of approximately 200 patients with leukemias or MDS will be required to provide information for the label in a future submission of a New Drug Application (NDA).

“We are gratified by the advice offered by the FDA on our proposed plan. Results of this pivotal study, if positive, may serve as the basis of an NDA filing and may support expanded investigation of sapacitabine in additional indications,” said Spiro Rombotis, Cyclacel’s President and CEO. “We will require additional meetings and dialogue with FDA before any NDA filing. Available data from our ongoing Phase 2 studies of sapacitabine include complete remissions at all doses tested with good tolerability, support previously-reported Phase 1 findings and suggest that this agent may address a substantial, unmet medical need in older patients with AML and MDS. We thank our clinical investigators, their staff and patients for helping us reach this important milestone.”

Sapacitabine is currently being studied in an open-label, multicenter, randomized Phase 2 trial of oral sapacitabine in elderly patients with AML who are previously untreated or in first relapse with the objective of evaluating three dosing schedules. Based on encouraging efficacy and safety data from the elderly AML patients, Cyclacel amended the protocol in 2008 to include a cohort of MDS patients who have been previously treated with hypomethylating agents. Following the protocol amendment the Phase 2 trial is anticipated to enroll a total of approximately 120 patients in two separate strata, AML and MDS, with approximately 60 patients in each stratum.

Cyclacel expects to report interim data from ongoing Phase 2 studies at upcoming major scientific meetings.

About sapacitabine

Sapacitabine acts through a dual mechanism, interfering with DNA synthesis by causing single-strand DNA breaks and inducing arrest of cell cycle progression mainly at G2/M-phase. Both sapacitabine and CNDAC, its major metabolite, have demonstrated potent anti-tumor activity in preclinical studies. Sapacitabine to date has been given as a single agent to approximately 170 patients with both hematologic malignancies and solid tumors in four Phase 1 studies. Data from a Phase 1 dose-escalation trial of sapacitabine were presented in December 2007 at the American Society of Hematology annual meeting. Two treatment schedules of sapacitabine were assessed in 47 evaluable, pretreated patients with advanced leukemias or MDS. Six patients achieved complete remission or complete remission without platelet count recovery and a further 15 achieved non-detectable levels of leukemic blast cells in their bone marrow. In addition to the Phase 2 study in elderly AML and MDS patients, sapacitabine is being studied in currently ongoing Phase 2 studies in patients with advanced cutaneous T cell lymphoma and non-small cell lung cancer.
