"During 2015, we continued to follow-up patients in SEAMLESS, our Phase 3 clinical trial evaluating sapacitabine in the front-line treatment setting of elderly patients with acute myeloid leukemia, or AML," said Spiro Rombotis, President and Chief Executive Officer of Cyclacel. "Approximately 7% of prespecified events remain to be observed before we can unblind the randomization code and report top-line results. We anticipate this happening by the end of the first half of 2016. At that point, we will analyze available data and determine submissibility to regulatory authorities. We also continued to follow patients in our Phase 1 trial of sapacitabine and seliciclib in patients with advanced solid tumors. Based on observations to date, we are extending the trial into a selected population of patients with breast cancer who are positive for BRCA mutations. Finally, we advanced CYC065, our second-generation CDK2/9 inhibitor, into a Phase 1, first-in-human study. Based on our preclinical data, we have determined the mechanistic rationale for the clinical development of CYC065 in certain hematological and solid tumor indications. We believe that 2016 may prove to be an important year for Cyclacel and we look forward to keeping you apprised of developments as the year unfolds."
2015 Achievements
Drug Development
Sapacitabine in SEAMLESS, pivotal Phase 3 study as first-line treatment in elderly patients with AML:
Continued follow-up and treatment of patients of this fully enrolled study.
7% of events remain before reporting topline results and mature data analysis.
Submitted to the European Medicines Agency (EMA) a Paediatric Investigation Plan application for sapacitabine.
Sapacitabine and seliciclib in Phase 1 study in patients with advanced solid tumors
Continued to follow patients treated with the all-oral combination of the CDK2/9 inhibitor seliciclib and sapacitabine in a Phase 1 trial in patients with advanced solid tumors. A breast cancer patient with BRCA mutations has been administered more than 70 cycles of the combination and continues on treatment.
Cyclin Dependent Kinase (CDK) Inhibitor Programs
Dosed the first patients in a Phase 1 trial of CYC065, the Company’s second-generation CDK2/9 inhibitor, to evaluate the safety, tolerability and pharmacokinetic profile of CYC065 in solid tumor and lymphoma patients.
Presented preclinical data on the molecular rationale and therapeutic potential in both hematologic and solid tumors of CYC065 at several medical conferences including the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2015, the Society of Hematologic Oncology (SOHO) 2015 Annual Meeting, the AACR (Free AACR Whitepaper)-NCI-EORTC International Conference and the San Antonio Breast Cancer Symposium (SABCS). The data show that:
CYC065 may reverse drug resistance associated with addiction of cancer cells to cyclin E, the partner protein of CDK2.
CYC065 may also inhibit CDK9-dependent oncogenic and leukemogenic pathways, including malignancies driven by certain oncogene and MLL rearrangements. MLL gene status and levels of Bcl-2 family proteins correlated with sensitivity of AML cell lines to CYC065.
CYC065’s anticancer activity presents an opportunity for patient stratification and combinations with anti-leukemic agents.
CYC065 was also effective against uterine cancer cells including those resistant to chemotherapy and was especially potent in uterine cancer cells in which cyclin E was amplified or overexpressed.
CYC065 could be active in triple-negative breast cancer.
First patients dosed in a Phase 2 investigator-sponsored trial (IST) evaluating seliciclib in patients with Cushing’s disease.
Presented preclinical data at the 4th Neuroblastoma Symposium in Newcastle Upon Tyne, UK demonstrating that CYC065 prolongs survival in MYCN-addicted neuroblastoma models.
Corporate Developments
Raised gross proceeds of $10 million from a public offering of common stock.
Entered into a Controlled Equity OfferingSM Sales Agreement with Cantor Fitzgerald & Co., as sales agent ("Cantor"), under which the Company may, from time to time, sell shares of its common stock having an aggregate offering price of up to $8.35 million through Cantor.
Entered into a license and supply agreement with ManRos Therapeutics regarding the development of oral seliciclib for the treatment of cystic fibrosis.
2016 Key Upcoming Business Objectives
Sapacitabine in SEAMLESS:
Continue follow-up of patients until the requisite number of events occur, which is anticipated by the end of the first half of 2016.
Report top-line results.
Following analysis of the mature data set determine submissibility to regulatory authorities for marketing approval.
Progress a Paediatric Investigation Plan for sapacitabine with the European Medicines Agency.
Sapacitabine in myelodysplastic syndromes (MDS):
Initiate a Phase 1/2 trial of sapacitabine in combination with other agents to determine safety and tolerability.
Plan a Phase 2 randomized controlled trial (RCT) of sapacitabine in combination with other agents following review of all relevant clinical data with mature follow-up.
Sapacitabine and seliciclib in Phase 1 study in patients with advanced solid tumors:
Initiate expansion of the Phase 1 study in a breast cancer patient population enriched for BRCA mutations.
Report updated Phase 1 data.
Cyclin Dependent Kinase (CDK) Inhibitor Programs
Report top-line results of the CYC065 Phase 1 trial in solid tumor and lymphoma patients.
Report data from seliciclib ISTs when available.
