Thank you Alex and thank you everyone for joining us today for our third quarter 2018 business update call. On today's call, I will begin with an overview of Cyclacel's clinical programs and progress in the third quarter 2018 and I will then turn the call over to Paul to provide financial highlights which will be followed by a Q&A session. Let's begin with an update of our lead program CYC065, a cyclin dependent kinase inhibitor or CDK2/9. In the ongoing battle against cancer we are facing a growing problem of resistance to cancer drugs. This occurs when drugs stop working against cancers after early effectiveness. Drug resistance increases the risk of disease progression and death, but can also undermine the significant resources expended in discovering and reimbursing innovations in cancer therapies. In many cancers resistance correlates with increased expression of members of the Bcl-2 protein family including Bcl-2, Mcl-1 and others. These proteins assist cancer cells in evading the effect of available therapies and promoting growth. They have been dubbed pro-survival proteins as they help cancer cells survive the effects of anticancer drugs and gain an advantage over normal cells. Suppressing pro-survival proteins is therefore a promising therapeutic strategy. Multiple studies show that suppression of Bcl-2 and/or Mcl-1 makes cancer cells again sensitive to the drug that stop working which then leads to cancer cell death. One such drug, venetoclax or Venclexta from [indiscernible] has been approved for second line CLL. It works by inhibiting Bcl-2 but has no significant activity against MCL-1. At Cyclacel our approach is to leverage our knowledge of cell cycle biology to disrupt cancer resistance. CYC065, our lead CDK inhibitor suppresses MCL-1 by interfering with transcription of cancer cells. Transcription is regulated by CDK9, an enzyme targeted by CYC065. In a first in human Phase 1 clinical study presented at the 2018 AACR conference this past spring, a single dose of CYC065 alone resulted in durable suppression of Mcl-1 for at least 24 hours in 11/13 patients treated at the recommended Phase 2 dose. Several patients whose cancers over expressed MCL-1, MYC and/or cyclin E experienced tumor shrinkage and disease stabilization. Following this Phase 1 data which demonstrated proof of mechanism and encouraging for clinical data showing synergy we have been preparing to test a double hit strategy of simultaneously suppressing Bcl-2 and MCL-1 in CLL patients by pairing venetoclax with CYC065. This study has now been open for enrollment and is evaluating escalating doses of CYC065 with venetoclax in patients with elapsed or refractory CLL. In this setting, after failure of front line therapy often with a BDK inhibitor, patients experience rapid growth of leukemia cells. Despite high initial response rates on single agent venetoclax, only one in four patients achieved complete remission. In addition, venetoclax progression is often correlated with elevation of MCL-1. We believe that targeting both MCL-1 and Bcl-2 with a combination of CYC065 and venetoclax may offer an important alternative to CLL patients in need. This study was initially done at MD Anderson Cancer Center as part of our recently announced alliance with this center of excellence. Let me make a few comments on the MD Anderson alliance. This three-year risk sharing partnership will enable clinical evaluation of three Cyclacel drug candidates in patients with hematological malignancies including CLL, AML, MDS, and other advanced leukemias. MD Anderson will conduct four clinical studies enrolling up to 170 patients which will investigate CYC065, CYC140 and sapacitabine either as single agents or in combination with approved therapies. The MD Anderson alliance allows us to power our track the development of our drugs in a cash sparing manner while utilizing MD Anderson's expertise to recruit eligible patients. Of note, Cyclacel remains the sponsor for these studies. In addition to the CLL study and also as part of the MD Anderson alliance, we have activated a first in human study of CYC140 polo-like-kinase or PLK1 inhibitor in patients with advanced leukemias. CYC140 which was discovered in-house has demonstrated clinically that it is a potent and effective inhibitor in both blood and solid cancers. Two further protocols are in development with MD Anderson investigators. They will evaluate combinations of CYC065 and sapacitabine either as single agents or in combination with approved agents. We are continuing enrollment in the CYC065 single agent Phase 1 study in patients with advanced solid cancers at the Dana-Farber Cancer Institute. Following the AACR report of the Part 1 data earlier this year, Part 2 is evaluating a more intensive dosing schedule of two days per week for two weeks of a three week cycle. The study will provide important safety and pharmacokinetic and pharmacodynamic data to inform combination trials including assessment of biomarkers related to CYC065's mechanism such as over expression or amplification of MCL-1, MYC or cyclin E. We are continuing discussions with various investigators in evaluating corporative group proposals to determine how CYC065 would add clinical benefit in a variety of other tumor indications suitable to the drug's mechanism. Let us now briefly turn to our DNA damage response program. We are pleased that the Phase 1B/2 clinical study evaluating sapacitabine in combination with the approved PARP inhibitor olaparib or AstraZeneca's Lynparza has started enrollments of BRCA positive patients with breast cancer. This investigator sponsored trial or IST conducted at Dana-Farber is planned to enroll approximately 64 patients. Cyclacel is providing sapacitabine investigation of drug and AstraZeneca olaparib. We have used this IST as another cost effective way to evaluate potential benefits of our drugs in difficult to treat cancers. PARP inhibitors are currently approved standard of care for homologous recombination deficient or HRD positive patients with breast and ovarian cancers which include those positive for BRCA mutations. Sapacitabine works by HRD relevant mechanism that is distinct from the MOA of PARP inhibitors. Sapacitabine has durable clinical activity including CR and PR in BRCA positive patients with breast, ovarian, and pancreatic cancers. The two therapies administered in combination could thus provide additional benefit to these patients for whom limited treatment options exist. Lastly, an update to our work with data from the sapacitabine Phase 3 seamless study in elderly AML. We met with three European regulatory authorities who provided consistent advice on next steps and a proposed methodology. This was an unexpected but welcome development which suggests that there is potentially a path forward to a regulatory submission. As a result of the guidance Cyclacel is evaluating a potential request for a meeting with the scientific advice working party of the European Medicines Agency. On the corporate front we have been fortunate to be working with a highly experienced Board of Directors over the years. Consistently with this history we have recently welcomed Dr. Robert Spiegel to the Board. Bob brings a 30-year track record in R&D and operational experience as a senior executive in biopharmaceutical companies and as an advisor to investment funds. He spent 25 years at Schering-Plough, acquired by Merck where he joined as the first director for oncology clinical research. Bob's expertise will support the development of our pipeline and our corporate strategy. In summary, we continue to execute on our strategy to rapidly advance CYC065 and CYC140 clinical development. Our recent achievements include entered into clinical development alliance with MD Anderson which enables power tracking of these preclinical candidates in a cash sparing manner. Opened enrollment of the Phase 1B clinical trial evaluating CYC065 in combination with venetoclax in patients with relapsed or refractory CLL. Activated a first in human Phase 1 trial of CYC140 PLK inhibitor in advanced leukemias. Dosed the first patient in a Phase 1b/2 IST of sapacitabine and olaparib combination in BRCA positive patients with breast cancer. Continued enrollment in Part 2 of the Phase 1 study evaluating CYC065 monotherapy in patients with advanced cancers and completed meetings with three EU Regulatory Authorities with the aim of determining next steps regarding the seamless data of sapacitabine in elderly patients with AML. I would now like to turn the call over to Paul to review our third quarter 2018 financials. Paul?
