Thank you, Bill, and good afternoon, everyone. It is a pleasure to update this afternoon on our corporate progress and financial results for the second quarter of 2013. The past quarter has been notable at Cyclacel, as we recorded a net income, greatly strengthened our balance sheet, continued to simplify our capital structure and progressed our clinical programs. In SEAMLESS, our pivotal Phase III study of sapacitabine as frontline treatment in elderly patients with acute myeloid leukemia, or AML, we have enrolled over 40% of the 485 patients required. We have signed an agreement with a clinical research organization for the purpose of expanding SEAMLESS outside the United States, and in particular, in Western Europe, which we anticipate will approximately double the number of enrolling sites in SEAMLESS for the remainder of enrollment. We also added approximately $24 million to our cash resources through the completion of an underwritten offering and the sale of 4 Cyclacel romidepsin-related patents. With these cash inflows, we expect our existing cash to fund us beyond the planned completion of the SEAMLESS study. Additionally, the dismissal of the romidepsin patent litigation with Celgene allows us to focus on the development of our pipeline. There is a high unmet medical need for the treatment of elderly patients with AML, and the disease is associated with high mortality and poor quality of life. Currently, there is no standard or satisfactory treatment in the United States for this group of patients. It is of note that the age of the patients with AML is an adverse prognostic factor for survival. SEAMLESS is the only Phase III study ongoing, which addresses this elderly frontline population who have either refused or are unfit for intensive chemotherapy treatment. In support of the SEAMLESS study, we have reported promising [ph] survival data from 46 patients, who were treated with the same alternating drug regimen of sapacitabine and decitabine as in the experimental arm of SEAMLESS. Median overall survival was 8.5 months. Notably, in the approximately 72% of these patients who were aged 75 years or older, median overall survival was 9.4 months. Recently, a pivotal file of decitabine as the same agent in older AMLs, the DACO-016 study, was published. In DACO-016, approximately 39% of patients randomized with decitabine were aged 75 years or older, and the median overall survival was 6.3 months. During the quarter, we reported updated Phase II median survival data in patients with myelodysplastic syndromes, or MDS, who failed frontline treatment whether one or both hypomethylating agents, or HMAs, azacitidine and/or decitabine. Patients were treated with sapacitabine as a single agent in this MDS study. The updated median survival data continued to be impressive and demonstrated that patients achieved nearly double the expected median survival reported in the literature for patients with MDS who are refractory to a single HMA. We expect to report primary endpoint data from this Phase II study later this year. Turning to our solid tumor program. We are evaluating sapacitabine in combination with seliciclib, our CDK inhibitor, as an orally administered sequential dose escalation regimen in heavily treated patients with solid tumors in an ongoing Phase I trial. Data presented on 38 patients at the 2013 American Association of Cancer Research Conference, or AACR, confirmed earlier evidence that the regimen achieved durable partial responses and prolonged stable disease in multiple cancer types, including breast, ovarian and pancreatic cancers, and in particular, in patients carrying BRCA mutations. We believe these clinical findings may be directly related to the drug's mechanism acting on the ability of cancer cells to undergo DNA repair through the homologous recombination pathway or HR. If confirmed, this could be an exciting finding, suggesting that a clinical development plan for sapacitabine in solid tumors could be targeted to keep cancer patients with HR defects such as BRCA. BRCA-deficient cancers are considered by clinicians to be incurable. It is very encouraging that data is emerging that point toward the potential for sapacitabine as a pipeline within a drug. While we have been concentrating our resources on the clinical development of sapacitabine, we have been opportunistic in terms of pursuing new approaches to develop the rest of our pipeline. For example, it was recently announced that our second clinical development candidate, seliciclib, is to be evaluated in an investigator-initiated clinical study to treat patients with rheumatoid arthritis or RA. This clinical study is supported by an approximately $1.5 million grant from the United Kingdom's Medical Research Council or MRC. The investigators who are leading this study believe that based on the extensive clinical data with seliciclib in solid tumors, seliciclib's mechanism of action and oral administration routes may be of benefit to patients with RA. In our earlier pipeline, CYC065, our novel, orally available second-generation CDK inhibitor targeting CDKs 2, 5 and 9, is currently in IND-directed development, supported by grant funding from the United Kingdom's Biomedical Catalyst fund. There is a strong preclinical rationale for the use of CYC065 as a targeted medicine in hematological indications. The grant allows for a translational biology effort to evaluate this and, in particular, in leukemias driven by the rearranged MLL or mixed lineage leukemia gene. I will now turn the call over to Judy, who will provide further details on our most recent clinical data. Judy?
