Spiro?.
Thank you, Alex, and good afternoon, everyone. On today's call, we will provide our first quarter business update and review progress with our clinical development programs.
In our transcriptional regulation program with CYC065, our lead CDK inhibitor, we are pleased to highlight two presentations at the recent American Association for Cancer Research or AACR 2018 Annual Meeting which confirmed a strong rationale for advancing our clinical development plans for CYC065 in certain liquid and solid cancers.
We have also achieved another key objective in our development pipeline by submitting an IND for CYC140 and internally discovered novel inhibitor of Polo-like-kinase 1, or PLK1. We have sufficient capital resources to fund currently planned programs through the first quarter of 2020.
Turning to the AACR meeting and the all presentation of clinical data from our ongoing first in human single agent dose escalation Phase 1 study of CYC065. The data presented by Dr.
[indiscernible] of the Dana Farber Cancer Institute in Boston demonstrated prolong reduction of Mcl-1 expression in 11 out of 13 patients treated at the recommended Phase 2 dose or RP2D following a single dose of CYC065 which was generally well-tolerated.
Preliminary anticancer activity was observed in six patients of which five were treated at the RP2D. Genetic data was available for three out of six patients and all three were reported by investigators to have molecular features of their cancers associated with CYC065's mechanism action including amplification of Mcl-1, MYC or cyclin E.
Reduction of Mcl-1 expression is a competitive area in cancer research and several companies are pursuing this target in both the clinical and clinical studies.
We believe that the results reported at AACR represent the first time that durable suppression of Mcl-1 has been reported in patients and we are keen to build on our lead in this important field. In addition to the clinical data, results from preclinical studies with CYC065 were also reported at the AACR.
In a poster titled strategic combination of the cyclin-dependent kinase inhibitor CYC065 with venetoclax to target anti-apoptotic proteins in chronic lymphocytic leukemia investigators led by Dr.
William Plunkett Professor and Deputy Chair Department of Experimental Therapeutics the University of Texas MD Anderson Cancer Center highlighted data that showed synergy of CYC065 in combination with the approved BCL-2 inhibitor venetoclax in chronic lymphocytic leukemia or CLL samples obtained from patients including those with 17p deletions.
The CYC065-venetoclax combination was also active in two CLL samples which were resistant to either agent alone. These findings support the hypothesis that dual targeting or the Mcl-1- and Bcl-2-dependent mechanisms could induce synergistic cell death. Let us discuss this treatment strategy in more detail.
CDK 2/9 inhibitors are designed to lower the threshold for killing cancer cells, which have become resistant to current treatment. Resistant cancer cells often over express Bcl-2 family proteins, such as Bcl-2, Bcl-XL or Mcl-1. These proteins play a central role in ensuring survival and ultimate immortality of these malignant cells.
In other words these cancer cells are very hard to kill with available therapies. Although venetoclax a drug that suppresses Bcl-2 was recently approved by FDA for CLL, it does not suppress Mcl-1. To make matters worse there are no drugs reported in the literature which have demonstrated durable suppression of Mcl-1 in the clinic.
Consequently and intensely competitive race is ongoing amongst several biopharmaceutical companies to address this major challenge in oncology therapeutics. Based on our own data and the supportive data from MD Anderson we believe that CYC065 may represent a solution to this problem when given in combination with venetoclax.
Such a two-hit strategy has been proven to work with other cancer drugs such as the combination of [PARP and Meche] inhibitors.
We are about to test this strategy in the clinic and have recently submitted to FDA a protocol for evaluating CYC065 in combination with venetoclax in patient with refractory CLL and expect to start enrolling soon after IRB approval.
In parallel to our activities in CLL, Part 2 of the Phase 1 first in human study is now open for enrollment of patients with advanced solid tumors and in particular those with amplifications of Mcl-1, MYCN or cyclin E.
In this part of the study we’ll be evaluating a more frequent schedule of CYC065 dose two days per week for the first two weeks of a three-week cycle.
The objectives of the study are to evaluate safety, pharmacokinetics and pharmacodynamics including collection of patient’s in specimens for assessment of biomarkers related to the drug's mechanism of action.
Discussing with principal investigators and/or corporate groups have progressed with the objective of evaluating CYC065 in both pediatric and adult patients with solid tumors.
The company is discussing with an investigator corporative group the potential evaluation of CYC065 in patients with neuroblastoma and mostly pediatric, life-threatening malignancy, frequently associated with MYCN amplification.
Pediatric neuroblastoma with MYCN amplification has a poor prognosis, and there is a need for new treatments for these children. CYC065 may work in neuroblastoma because inhibition of CDK 2/9 is synthetically lethal with MYCN amplification. In other words, MYCN-amplified cancers have been shown to be very sensitive to the drug's mechanism.
There is a strong preclinical rationale for the evaluation of CYC065 in neuroblastoma, including improved survival in MYCN-amplified animal models.
In another study to be conducted as an Investigator Sponsor Trial or IST, CYC065 will be evaluated in adult and pediatric patients with leukemias, including acute myeloid leukemia, or AML, acute lymphocytic leukemia, or ALL, and in particular, those with mixed lineage leukemia rearrangements or MLL-r.
This IST is undergoing institutional review and is expected to open later this year. Cyclacel will provide CYC065 but will not be paying for the costs of patient enrollment. Let us now turn to our DNA Damage Response, or DDR program with sapacitabine.
We have jointly developed in collaboration with an academic center and a pharmaceutical company a protocol for a clinical study that will evaluate a combination regimen of sapacitabine and an approved PARP inhibitor. This will be a Phase Ib/2 Investigator Sponsor Trial administering the combination regimen to patient with BRCA-mutant breast cancer.
In this case Cyclacel will provide sapacitabine investigational drug product but will not be responsible for patient equipment costs. We will provide more details once this IST gets underway. PARP inhibitors given a single agent are standard of care in homologous recombination deficient, or HR deficient, breast and ovarian cancers.
HR deficient cancers include those that are positive for BRCA mutations. Preclinical evidence and early clinical data also support investigational use of PARP inhibitors in HR deficient, pancreatic and prostate cancers. There are no other approved drugs for HR deficient cancers, and the unmet medical need exists to improve on the standard-of-care.
Sapacitabine works by an HR deficient-relevant mechanism of action and has shown promising and durable clinical activity in BRCA positive patients with breast, ovarian and pancreatic cancers.
In parallel, as part of our DDR program, we are studying a sequential regimen of sapacitabine and seliciclib our first generation CDK inhibitor in BRCA positive patients. The aim of this strategy is to disrupt the ability of cancer cells to repair damage to the DNA and thus restore their sensitivity to anticancer therapy.
Promising and durable anti-tumor activity has been observed in Parts 1 and 2 of the study and in particular a subgroup of 45 patients with breast, ovarian and pancreatic cancers who tested positive for BRCA mutations.
An extension of Part 1 of the study has enrolled a further 20 BRCA positive patients with breast cancer and is now in the follow-up stage.
Based on these results and investigator encouragement we’re enrolling a Part 3 to expand observations and test a revised dosing schedule in BRCA positive patients with advanced breast, ovarian and pancreatic cancers.
Turning to our newest program in mitosis control we have an IND for CYC140 our PLK1 inhibitor in preparation for a first in human study. This is an exciting moment for this internal discovery compound the target of which was discovered a Prof. David Glover Cyclacel’s Chief Scientist.
We will provide more details on CYC140 and its development strategy once the Phase 1 study get underway. Let us now turn to sapacitabine in AML and many of you know data from our SEAMLESS Phase 3 study were presented by the studies Chair at the American Society of Hematology or ASH Annual Meeting last December.
Although the study did not reach its primary endpoint of statistically significant superiority in overall survival we are encouraged by the higher complete remission rate on the sapacitabine alternating with decitabine investigational arm.
A large prespecified group with low peripheral white blood cell count comprising about two-thirds of the study population showed improved overall survival and complete remission rate.
The ASH Presentation included additional data from prespecified and exploratory analysis of subgroups that may benefit from treatments with the sapacitabine-decitabine alternating regimen.
The company believes that the subgroup results have defined a patient population for whom the sapacitabine regimen may represent an improvement over low intensity therapy by decitabine alone.
After completing the further statistical and exploratory analyses of the SEAMLESS Phase 3 results we have prepared written documents for submission to regulatory authorities with the objective of determining a potential regulatory pathway for sapacitabine in AML.
We will be making submissions to certain European national authorities during the second quarter and depending on the availability expect to have a pain initial feedback starting in the third quarter on the basis of which the company will determine next steps.
We're looking forward to an exciting future for Cyclacel following the encouraging Phase 1 data we are advancing our clinical programs led by CYC065 in selected patient populations informed by our scientific expertise in cancer biology. Before handing the call over to Paul for a review of the financials, let me review our goals for the rest of 2018.
Report updated CYC065 Phase 1 data in patients with advanced cancers initiates CYC065 Phase 1b in relapsed refractory CLL in combination with venetoclax. Start enrollment in a Phase 1b/2 IST of CYC065 in pediatric patients with neuroblastoma.
Start enrollment in a Phase Ib/2 IST of a combination regimen of an approved PARP inhibitor and sapacitabine in patients with BRCA mutant breast cancer.
Conduct regulatory authority meetings regarding the SEAMLESS study of sapacitabine in AML, update mature data from the Part 1 extension of the sapacitabine and seliciclib regimen in BRCA positive patients with advanced breast cancer and complete Part 3 enrollment in BRCA positive, breast, ovarian and pancreatic cancer patients and IND review for CYC140 PLK1 inhibitor.
We will now review our financials.

Thank you, Spiro. As you saw from our press release, for the quarter ended March 31, 2018, our cash and cash equivalents totaled $21.7 million compared to $23.9 million as of December 31, 2017. The decrease is primarily due to $2.2 million of net cash used in operating activities.
Research and development expenses were $0.8 million compared to $1.3 million in period in 2017. General and administrative expenses for the three months ended March 31, 2018 and 2017 were $1.4 million. The U.K. government research and development tax credit for the quarter was $0.2 million.
Other income net for the three months ended March 31, 2018 was $0.6 million compared to $0.8 million for the same period in 2017.
The $0.6 million is primarily related to income received under an Asset Purchase Agreement with ThermoFisher Scientific company formerly Invitrogen Corporation, in respect of certain assets and intellectual property related to chimeric antigen receptor-T cell or CAR-T manufacturing technology sold by the company to ThermoFisher Scientific company in December 2005.
Net loss for the three months March 31, 2018 was $1.3 million compared to $1.6 million for the same period last year. As of March 31, 2018, 11,997,447 shares of common stock and 264 shares of Series A preferred stock or 3% of the class are outstanding.
We expect current cash to be able to fund operations and planned clinical programs through the first quarter of 2020. Operator, we're now ready to take questions..
