Berkeley Heights, NJ, August 14, 2012 — Cyclacel Pharmaceuticals, Inc. (NASDAQ: CYCC, NASDAQ: CYCCP; Cyclacel or the Company), a biopharmaceutical company developing oral therapies that target the various phases of cell cycle control for the treatment of cancer and other serious disorders today reported its financial results and business highlights for the second quarter ended June 30, 2012.

The net loss for each of the second quarters of 2012 and 2011 was $3.6 million.  For the six months ended June 30, 2012, the Company reported a net loss of $6.5 million as compared to a net loss of $8.1 million for the six months ended June 30, 2011. As of June 30, 2012, cash and cash equivalents totaled $20.0 million.  The Company’s net loss applicable to common stockholders for the second quarter of 2012 was $3.8 million, or $0.06, per basic and diluted share, compared to a net loss applicable to common stockholders of $3.7 million, or $0.08, per basic and diluted share for the second quarter of 2011.  The Company’s net loss applicable to common stockholders for the six months ended June 30, 2012 was $6.9 million, or $0.12, per basic and diluted share, compared to a net loss applicable to common stockholders of $8.5 million, or $0.18, per basic and diluted share for the six months ended June 30, 2011.

“Cyclacel’s focus remains on the successful execution of SEAMLESS, our Phase 3 study of sapacitabine as front-line treatment in acute myeloid leukemia (AML).  With 35 clinical sites open and enrolling in the U.S., we anticipate reaching the second planned periodic safety review in late 2012 or early 2013,” said Paul McBarron, Executive Vice President, Finance and Chief Operating Officer of Cyclacel. “Sapacitabine continues to demonstrate promising safety and efficacy thus far in both hematological malignancies and solid tumors.  At ASCO 2012 we reported promising median overall survival of approximately 8.4 months for single-agent sapacitabine in patients with myelodysplastic syndromes (MDS), who had failed hypomethylating agents.  At ASCO 2012 we also reported promising data from our Phase 1/2 study of sapacitabine in combination with our second drug, seliciclib, including responses and stable disease in patients who are BRCA-mutation carriers.  In addition to continuing SEAMLESS enrollment, we look forward to overall survival data from the investigator-led, Phase 2/3 “Pick a Winner Programme / LI-1” study comparing single-agent sapacitabine to low dose cytarabine”.

Business Highlights

·                  In June 2012 at the American Society of Clinical Oncology (ASCO) 2012 Annual Meeting, reported new data from an ongoing, multicenter, Phase 2 randomized trial of single-agent oral sapacitabine capsules, in older patients with MDS after treatment failure of the front-line hypomethylating agents, azacitidine (Vidaza®) and/or decitabine (Dacogen®). Median overall survival to date for all patients is 252 days or approximately 8.4 months.

·                  At the ASCO 2012 Annual Meeting, presented new data from an open label, single arm, Phase 1 escalation trial of a combination of the Company’s drug candidates, sapacitabine and seliciclib, as an orally-administered sequential treatment regimen in heavily-pretreated patients with advanced solid tumors. The maximum tolerated dose (MTD) for the regimen was reported as sapacitabine 50 mg twice daily followed by seliciclib 1200 mg twice daily. Pharmacodynamic effects were observed in skin biopsies showing a 2.3-fold increase in H2AX staining post-sapacitabine (n=16; p=0.007) and a further 0.58-fold increase post-seliciclib (n=12; p=0.069). Among 19 patients treated at the MTD, 3 partial responses (PR) occurred in patients with breast, ovarian and pancreatic cancer and 1 stable disease in a patient with ovarian cancer. Thirteen of the 19 patients are BRCA-mutation carriers, of which 7 were poly ADP-ribose polymerase (PARP) inhibitor-naïve and 6 had prior PARP inhibitor treatment. All four responding patients were PARP inhibitor-naïve, BRCA-mutation carriers. Stable disease was achieved in 6 additional patients treated with the other dosing schedules. The number of treatment cycles administered ranged from 2 to over 15 cycles. The breast cancer patient who achieved PR remains on study with over 15 cycles and both ovarian cancer patients remain on study with over 2 and 12 cycles respectively.

·                  In May 2012, announced completion of enrollment of the Phase 2 portion of the investigator-led, Phase 2/3 multicenter, randomized trial comparing sapacitabine to low dose cytarabine (the “Pick a Winner Programme / LI-1 Trial”) in patients aged 60 years or older with previously untreated AML or high risk MDS who are unfit for intensive chemotherapy. The study enrolled over 100 patients. The investigators anticipate that, as required by the protocol, the study’s data safety monitoring board will meet within 2012 to review the data and assess overall survival.

·                  In April 2012, presented preclinical results for three Cyclacel compounds, sapacitabine, Polo-Like Kinase 1 and Aurora A kinase inhibitors including CY116, at the 103rd Annual Meeting of the American Association of Cancer Research.

·                  In April 2012, announced that the U.S. Patent and Trademark Office issued U.S. Patent No. 8,124,593 (‘593), which grants claims to a specified method of administration of sapacitabine and extends existing composition of matter US patent protection and supports US market exclusivity out to 2030.

·                  The Company also reported that Mr. McBarron, our Executive Vice President, Finance and Chief Operating Officer would be conducting the earnings call and would be performing additional duties as a result of Spiro Rombotis taking medical leave to recuperate from surgery that removed a mass discovered during a routine physical examination.  Mr. Rombotis is expected to make a full recovery and reassume his full duties in early September 2012.

Second Quarter and Year to Date 2012 Financial Results

Product Revenue

On August 10, 2012, the Company entered into an agreement with Sinclair Pharmaceuticals Limited (“Sinclair”) to early terminate, effective September 30, 2012, the distribution agreements relating to the promotion and sale of Xclair®, Numoisyn® Lozenges and Numoisyn® Liquid. The agreement includes a minimum royalty arrangement based on future net revenues, under which Sinclair will pay the Company a minimum of approximately $1.0 million in quarterly instalments over the next three years ending on September 30, 2015.

Research and Development Expenses

Research and development expenses in the second quarter of 2012 were $1.7 million compared to $1.9 million for the same period in 2011. Research and development expenses for the six months ended June 30, 2012 and 2011 were $3.1 million and $4.9 million, respectively.  The decrease in costs was primarily due to a contractual payment of $1.6 million to Daiichi Sankyo during the first quarter of 2011 related to a milestone payment triggered by the opening of enrollment in the SEAMLESS Phase 3 trial.

Selling, General and Administrative Expenses (SG&A)

Total SG&A expenses for the second quarter of 2012 were $2.4 million, compared to $2.0 million for the same period in 2011.
