The Company’s net loss applicable to common shareholders for the three months ended March 31, 2018 was $1.4 million. As of March 31, 2018, cash and cash equivalents totaled $21.7 million.
"Two presentations at the recent American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting highlighted CYC065, our lead CDK inhibitor drug candidate, confirming a strong rationale for advancing its clinical development in certain liquid and solid cancers," said Spiro Rombotis, President and Chief Executive Officer of Cyclacel. "The oral presentation confirmed proof of mechanism in patients with advanced solid tumors. Durable suppression of Mcl-1 in 11 of 13 patients was demonstrated for the first time in the literature after a single dose at the recommended Phase 2 level. In addition, anticancer activity was observed in patients with MYC amplified tumors, confirming the promise of a CDK inhibition strategy against this very difficult to treat tumor type. The poster presentation demonstrated preclinical synergy of CYC065 with venetoclax, supporting the Company’s plans to pursue a venetoclax combination study in patients with relapsed/refractory chronic lymphocytic leukemia, or CLL. We have also achieved another important objective by submitting an IND for CYC140, an internally-discovered, novel inhibitor of Polo-like-kinase 1, or PLK1."
Key Highlights
CYC065, CDK2/9 inhibitor, Phase 1 data at oral presentation at the 2018 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting. In part 1 of this ongoing, first-in-human, single agent, dose escalation study, prolonged reduction of Mcl-1 expression was observed 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 6 patients, of which 5 were treated at the RP2D; genetic data was available for 3 out of 6 patients and all 3 were reported by investigators to have molecular features of their cancers associated with CYC065’s mechanism of action, including amplification of Mcl-1, MYC or cyclin E.
Following completion of part 1, Cyclacel has initiated part 2 of the study evaluating CYC065 in a more frequent dosing schedule of 2 days per week for 2 weeks of a three-week cycle. Part 2 will enroll patients with advanced cancers and evaluate efficacy in Mcl-1, MYC or cyclin E amplified cancers. Several biomarkers relevant to CYC065’s mechanism of action will be assessed.
A poster was presented at the 2018 AACR (Free AACR Whitepaper) meeting titled "Strategic combination of the cyclin-dependent kinase inhibitor CYC065 with venetoclax to target anti-apoptotic proteins in chronic lymphocytic leukemia". The preclinical study led by William Plunkett, PhD, Professor and Deputy Chair, Department of Experimental Therapeutics, The University of Texas MD Anderson Cancer Center, highlighted data that showed the efficacy of CYC065 therapy in combination with the Bcl-2 inhibitor, venetoclax (AbbVie), in CLL samples, 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 of the Mcl-1- and Bcl-2-dependent mechanisms could induce synergistic cell death.

The Company plans to initiate a clinical study in patients with relapsed/refractory CLL in combination with venetoclax, in whom durable suppression of Mcl-1 may be beneficial.
Part 3 of the Phase 1 combination study of sapacitabine and seliciclib (Cyclacel’s first generation CDK inhibitor) continues enrolment with the objective of testing a revised dosing schedule in patients with advanced cancer, including BRCA positive breast, ovarian and pancreatic cancer patients.
The Company has completed statistical and exploratory analyses of the SEAMLESS Phase 3 study results and is preparing briefing documents for submission to regulatory authorities with the objective of determining a potential regulatory pathway for sapacitabine in AML. The Company believes that the subgroup results have defined a patient population for whom the sapacitabine regimen may represent an improvement over low intensity treatment by decitabine alone.
2018 Key Upcoming Business Objectives
Report updated CYC065 Phase 1 data in patients with advanced cancers;
Initiate 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 1b/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 combination in BRCA positive advanced breast cancer patients and complete part 3 enrollment of the sapacitabine and seliciclib combination in BRCA positive, breast, ovarian and pancreatic cancer patients;
IND review for CYC140 PLK1 inhibitor.
Financial Highlights
As of March 31, 2018, cash and cash equivalents totaled $21.7 million, compared to $23.9 million as of December 31, 2017. The decrease of $2.2 million was primarily due to net cash used in operating activities.
Research and development expenses were $0.8 million for the three months ended March 31, 2018 as compared to $1.3 million for the same period in 2017. The decrease was primarily due to reduced study and related costs associated with completion of the SEAMLESS study.
General and administrative expenses were $1.4 million for each of the three months ended March 31, 2018 and 2017.
Other income, net for the three months ended March 31, 2018 was $0.6 million compared to $0.8 million for the same period of the previous year. The decrease is primarily related to income received under an Asset Purchase Agreement with ThermoFisher Scientific Company, or TSC, (formerly Invitrogen Corporation), in respect of certain assets and intellectual property related to chimeric antigen receptor-T cell (CAR-T) manufacturing technology sold by the Company to TSC in December 2005.
The United Kingdom research and tax credits were $0.2 million for the three months ended March 31, 2018 compared to $0.3 million for the same period in 2017.
Net loss for the three months ended March 31, 2018 was $1.3 million compared to $1.6 million for the same period in 2017.
