"After announcing In July that the first patient had been dosed with oral fadraciclib, two additional patients with advanced solid tumors have been treated, completing enrolment of the first dose level," said Spiro Rombotis, President and Chief Executive Officer. "We are encouraged by investigator interest in our fadraciclib 065-101 solid tumor study. In earlier clinical studies fadraciclib has demonstrated single-agent activity, including durable PR. We believe that fadraciclib is a leading, transcriptionally-active CDK inhibitor with a differentiated product profile. Pipeline momentum will continue to build with the planned opening of protocol 065-102, an oral fadraciclib study in patients with hematological malignancies, and later with the initiation of two similar protocols in solid tumors and hematological malignancies for our novel PLK1 inhibitor, CYC140. The second half of 2021 is an exciting period for Cyclacel, as we expand our clinical programs and increase our visibility as an oncology leader focused on cell cycle inhibition for the treatment of cancer. We look forward to reporting further updates as data from these studies become available."
Key Corporate Highlights
Oral fadraciclib – First three patients with advanced solid tumors dosed in the 065-101 Phase 1/2, registration-directed trial. The study includes multiple cohorts defined by histology thought to be sensitive to the drug’s mechanism of action and informed by the clinical activity of fadraciclib in MCL1, MYC and/or cyclin E amplified cancers. The cohorts include breast (metastatic, hormone receptor positive, post-CDK4/6 inhibitor; HER-2 refractory; or triple negative), cholangiocarcinoma, colorectal (including KRAS mutant), endometrial, hepatocellular, ovarian cancers and certain lymphomas. The study design also includes a basket cohort which will enroll patients with relevant biomarkers to the drug’s mechanism regardless of histology. Previously single agent, intravenous fadraciclib has demonstrated durable suppression of MCL1 and other mechanistically-related proteins, including cyclin E and MYC, at tolerated doses.
Oral CYC140 – continued progress with IND-directed activities and manufacturing of clinical trial supplies. Initial data in preclinical models show that KRAS mutant cancers are sensitive to oral CYC140 inhibition. The Company expects to begin a study in patients with solid tumors in the second half of 2021. Similar to the fadraciclib clinical program, the CYC140 Phase 1/2 study will be a registration-directed trial using a streamlined design that will first determine the recommended Phase 2 dose (RP2D) for single-agent CYC140. Once the RP2D has been established, the trial will immediately enter into a proof-of-concept, cohort stage, using a Simon 2-stage design, where single agent CYC140 will be administered to patients across multiple cohorts based upon those histologies thought to be sensitive to the drug’s mechanism of action.

Financial Highlights
As of June 30, 2021, cash and cash equivalents totaled $43.6 million, compared to $47.8 million as of March 31, 2021. The decrease of $4.2 million was primarily due to net cash used in operating activities. The Company estimates that the cash resources will fund currently planned programs through early 2023.
Research and development expenses were $4.1 million for the three months ended June 30, 2021 as compared to $1.2 million for the same period in 2020. Research and development (R&D) expenses relating to fadraciclib increased by approximately $1.9 million for the three months ended June 30, 2021 with the start of the CYC065-101 study of fadraciclib in solid tumors and preparations for opening the 065-102 study of fadraciclib in leukemias. Additionally, R&D expenses related to CYC140 increased $1.0 million for the quarter as IND-directed activities are approaching completion and clinical trial supplies are being manufactured.
General and administrative expenses for the three months ended June 30, 2021 were $2.0 million, compared to $1.3 million for the same period of the previous year due to costs of approximately $0.4 million related to exiting a long-term facility lease, increased legal and professional expenses and recruitment costs.
United Kingdom research & development tax credits were $1.0 million for the three months ended June 30, 2021, as compared to $0.3 million for the same period in 2020 due to the increase in R&D expenditure.
Net loss for the three months ended June 30, 2021 was $5.1 million, compared to $2.2 million for the same period in 2020.
