BERKELEY HEIGHTS, N.J., Jan. 7, 2013 (GLOBE NEWSWIRE) -- Cyclacel
Pharmaceuticals, Inc. (Nasdaq:CYCC) (Nasdaq:CYCCP) (Cyclacel or the Company)
today reviewed 2012 achievements and provided an outline of the Company's key
clinical development objectives for 2013, which will be highlighted at the
Company's presentation during the Biotech Showcase™ 2013 Conference at 3:15 pm
Pacific Time on Monday, January 7, 2013, at the Parc 55 Wyndham Hotel in San
Francisco, CA.

"During 2012, we advanced the clinical development of sapacitabine in multiple
indications. For example, in our SEAMLESS, Phase 3, registration-directed
study, of sapacitabine in elderly patients with newly diagnosed acute myeloid
leukemia (AML), our lead indication, we exceeded 100 patients enrolled with 37
trial sites open," said Spiro Rombotis, President and Chief Executive Officer
of Cyclacel. "In addition, the independent committee overseeing SEAMLESS
recently recommended that the study should continue as planned and identified
no safety or efficacy concerns. We are encouraged by the continued
investigator interest in SEAMLESS and plan to open additional sites during
2013. Updated survival data in AML with sequential administration of
sapacitabine and decitabine is promising and provided further support for the
SEAMLESS Phase 3 study. With regard to other disease indications, recent Phase
2 data demonstrated that sapacitabine nearly doubled expected survival of
elderly patients with myelodysplastic syndromes (MDS) after treatment failure
of hypomethylating agents. For 2013, we are focused on executing our product
development plan for sapacitabine in AML, MDS and other cancers using, among
other funds, the proceeds of the recent funding agreement with Aspire Capital.
We are also advancing CYC065, our second-generation cyclin dependent kinase
(CDK) inhibitor, enabled by a $1.9 million grant from the UK Government."

2012 Milestones and Accomplishments

Drug Development

  * Convened the second periodic meeting of the independent Data Safety
    Monitoring Board (DSMB) of the SEAMLESS, Phase 3, randomized,
    registration-directed study of sapacitabine in elderly patients with AML.
    The DSMB recently recommended that the study should continue as planned
    after reviewing available data from 119 randomized patients. The DSMB
    noted that no safety or efficacy concerns were identified. SEAMLESS is
    being conducted under a Special Protocol Assessment (SPA) agreement with
    the U.S. Food and Drug Administration (FDA).
     
  * Reported results at the 2012 American Society of Hematology Annual Meeting
    from the pilot study and lead-in phase of SEAMLESS evaluating the same
    treatment regimen of sapacitabine dosed sequentially with decitabine, as
    used in the experimental arm of SEAMLESS. Among 46 patients treated median
    overall survival is 238 days, or approximately 8 months. The number of
    patients still alive at 3 months was 38 (83%), at 6 months 30 (65%), at 12
    months 16 (35%) and at 18 months 12 (26%). Sixteen patients (35%) survived
    1 year or longer. Among 33 patients (72%) who are 75 years or older,
    median overall survival is 263 days, or approximately 9 months, and 1-year
    survival is 36%. Nineteen patients (41%) responded including 10 with
    complete responses (CRs). Median time to response is 2 cycles, i.e., one
    cycle of decitabine and one cycle of sapacitabine (range 1-10).
    Twenty-seven patients (59%) received 5 or more cycles. Two dose-limiting
    toxicities were observed. Thirty-day mortality from all causes was 4%.
    Sixty-day mortality from all causes was 13%.
     
  * Published in The Lancet Oncology peer-reviewed journal results from a
    Phase 2 randomized trial of single-agent sapacitabine in elderly patients
    aged 70 years or older with newly diagnosed AML or AML in first relapse.
     
  * Presented updated data at two separate sessions at The Eighth Annual
    Hematologic Malignancies 2012 Conference from an ongoing, multicenter,
    Phase 2 randomized trial of sapacitabine in older patients with
    intermediate-2 or high-risk MDS after treatment failure of front-line
    hypomethylating agents, such as azacitidine (Vidaza®) and/or decitabine
    (Dacogen®). Median overall survival to date for all 63 patients in the
    Phase 2 study is approximately 8 months. For 41 out of 63 patients with
    10% to 19% blasts in their bone marrow median overall survival is
    approximately 9 months. Twenty-two percent of patients are still alive and
    longer follow-up is needed to assess 1-year survival and overall survival
    of each arm. Earlier data from this study were presented at the American
    Society of Clinical Oncology (ASCO) 2012 Annual Meeting.
     
  * Participated in the Phase 2 portion of the UK investigator-sponsored,
    Phase 2/3 randomized trial comparing, among other drugs, sapacitabine
    versus low dose cytarabine. Approximately 55 patients aged 60 years or
    older with previously untreated AML or high-risk MDS were treated with
    sapacitabine with approximately half in the "Pick a Winner Programme" and
    half in the "LI-1 Trial" protocols. Recently, the study's Data Monitoring
    & Ethics Committee did not recommend sapacitabine for the next phase of
    the LI-1 Trial based on the criterion that sapacitabine as a single agent
    was not likely to double one year survival versus low-dose cytarabine. The
    company-sponsored, ongoing SEAMLESS study of previously untreated AML
    patients aged 70 years or older is comparing the regimen of sapacitabine
    dosed sequentially with decitabine versus decitabine alone with the aim of
    reducing the risk of death by 27.5%.
     
  * Presented new data at the ASCO 2012 Annual Meeting 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 for 7 days followed by
    seliciclib 1200 mg twice daily for 3 days. 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 4 responding patients were PARP
    inhibitor-naïve, BRCA-mutation carriers. Stable disease was achieved in 6
    additional patients treated with the dosing schedules below MTD.
     
  * Presented preclinical translational research results for sapacitabine at
    the 103rd Annual Meeting of the American Association of Cancer Research
    (AACR). The findings further support the potential for sapacitabine to be
    used alone or in combinations to treat homologous recombination repair
    (HRR) defective tumors, such as ATM or BRCA defective tumors.
     
  * Highlighted the personalized medicine potential of sapacitabine at the 8th
    National Cancer Research Institute Cancer Conference with translational
    findings demonstrating the combination potential of sapacitabine in
    patients with BRCA1/2 or HRR pathway defects.
     
  * Issued U.S. Patent No. 8,124,593 by The U.S. Patent and Trademark Office,
    which grants claims to a specified method of administration of
    sapacitabine, adding to existing composition of matter patents and
    supporting market exclusivity out to 2030.
     
  * Received a grant award of approximately $1.9 million from the UK
    Government's Biomedical Catalyst to complete investigational new drug
    (IND)-directed preclinical development of CYC065, a novel, orally
    available, second generation, CDK inhibitor.
     
  * Presented preclinical results for Cyclacel's Polo-Like Kinase 1 (Plk1) and
    Aurora A kinase inhibitors, at the 103rd Annual Meeting of the AACR. Also,
    separately, reported biological characterization of a potent and
    selective, preclinical-stage, Plk1 inhibitor, from Cyclacel's novel Plk1
    inhibitor series with sensitivity in a panel of esophageal cancer cell
    lines correlating with p53 status, a potential biomarker to identify
    responders in future clinical trials.

Corporate Developments

  * Entered into a common stock purchase agreement with Aspire Capital Fund,
    LLC (Aspire). Aspire has committed to purchase up to $20 million of
    Cyclacel's common stock from time to time as directed by Cyclacel over the
    next two years at formula prices based on the market price at the time of
    each sale. Under the agreement, Aspire purchased $1 million of Cyclacel
    common stock at a per share price equal to the closing price of $6.29 on
    December 13, 2012 the date immediately prior to the closing date.
     
  * Entered into a purchase agreement with certain existing institutional
    stockholders raising $2.9 million, net of certain fees and expenses. The
    proceeds from the financing are being used to fund ongoing
    litigation-related expenses involving specified Cyclacel intellectual
    property.
     
  * Entered into a Securities Exchange Agreement with Tang Capital Partners,
    LP (Tang) pursuant to which the Company issued 631,561 shares of its
    common stock to Tang in exchange for Tang's delivery to the Company of
    351,990 shares of the Company's 6% Exchangeable Convertible Preferred
    Stock. Tang approached the Company with the proposed exchange transaction.
    The terms of the exchange were determined by arms-length negotiations
    between the parties. Following this transaction a total of 861,152 shares
    of Preferred Stock will remain outstanding.
     
  * Entered into an agreement with Sinclair Pharmaceuticals Limited to
    terminate the distribution agreements relating to the promotion and sale
    of Xclair®, Numoisyn® Lozenges and Numoisyn® Liquid in exchange for a
    minimum of approximately $1 million in royalty payments through September
    2015.
     
  * Implemented a 1-for-7 reverse stock split of shares of common stock in
    order to satisfy the $1.00 minimum bid requirement for continued listing
    on the NASDAQ Global Market.
