– On Track to Start Oral Fadraciclib Phase 2 Proof of Concept in 1H 2023 and Report Interim data in 2H 2023 – – Expect to Report Final Data from Fadraciclib 065-101 Dose Escalation – – Expect to Report Initial Data from Oral Plogosertib 140-101 Dose Escalation – – Management to Host Conference Call at 4:30 pm ET Today – BERKELEY HEIGHTS, N.J., March 06, 2023 (GLOBE NEWSWIRE) — Cyclacel Pharmaceuticals, Inc. (NASDAQ: CYCC, NASDAQ: CYCCP; “Cyclacel” or the “Company”), a biopharmaceutical company developing innovative medicines based on cancer cell biology, today announced fourth quarter and full year 2022 financial results and provided a business update. “After a productive 2022, we anticipate that 2023 will be even more exciting for Cyclacel. We plan to advance oral fadraciclib, our CDK2/9 inhibitor, into Phase 2 proof-of-concept evaluating multiple cancer cohorts, and also further explore the anti-cancer potential of our oral PLK1 inhibitor plogosertib,” said Spiro Rombotis, President and Chief Executive Officer. “We expect three key data readouts this year, including pharmacokinetic (PK), pharmacodynamic (PD), safety and activity data from the dose escalation part of our fadraciclib 065-101 Phase 1/2 study, initial clinical activity data from the Phase 2 proof of concept stage of the study and PK, PD, safety and activity data from the dose escalation part of our 140-101 Phase 1/2 study of plogosertib. These data have the potential to further demonstrate that fadraciclib and plogosertib are differentiated from other molecules in their respective classes.” “We are pleased with our pipeline’s progress in 2022 and believe that we have the opportunity to demonstrate promising results for our two drug candidates, fadraciclib and plogosertib, in the year ahead,” said Mark Kirschbaum, M.D., Chief Medical Officer. “At the recent ENA 2022 Symposium we reported fadraciclib’s good tolerability profile and clear anti-cancer signals. We are currently recruiting patients at dose level 6a of 125mg administered orally twice daily for four out of four weeks. We plan to optimize the dosing schedule and move into Phase 2 testing of the tumor types that should be most sensitive to fadraciclib treatment. We are also advancing plogosertib through dose escalation and are now recruiting patients at dose level 4 in our Phase 1/2 solid tumor study. We have observed efficacy at lower dose levels with three patients on treatment for three to eight cycles. We expect to report additional data of our mechanistically differentiated PLK1 inhibitor from this trial later this year. We remain enthusiastic about Cyclacel’s advancing clinical-stage pipeline and look forward to presenting emerging data from these two programs during the year.“ Key Business Objectives for 2023 Report final data from dose escalation stage and RP2D determination from the 065-101 study of oral fadraciclib in patients with advanced solid tumors and lymphomaFirst patient dosed with oral fadraciclib in Phase 2 proof-of-concept stage of 065-101 study in patients with advanced solid tumors and lymphomaReport interim Phase 1 data from 140-101 study of oral plogosertib in patients with advanced solid tumors and lymphomaReport interim data from initial cohorts in Phase 2 proof-of-concept stage of 065-101 study with oral fadraciclib in patients with advanced solid tumors and lymphomaReport interim data from dose escalation stage of 065-102 study with oral fadraciclib in patients with advanced leukemiaReport final data from dose escalation stage of 140-101 study with oral plogosertib in advanced solid tumors and lymphoma Financial Highlights As of December 31, 2022, cash and cash equivalents totaled $18.3 million, compared to $36.6 million as of December 31, 2021. Net cash used in operating activities was $20.8 million for the twelve months ended December 31, 2022 compared to $18.5 million for the same period of 2021. The Company estimates that its available cash, including the United Kingdom research & development tax credit receivable of $4.7 million, will fund currently planned programs into the fourth quarter of 2023. Research and development (R&D) expenses were $6.7 million and $20.3 million for the three months and year ended December 31, 2022, as compared to $4.6 million and $15.5 million for the same period in 2021. R&D expenses relating to fadraciclib were $5.3 million and $14.0 million for the three months and year ended December 31, 2022, as compared to $3.4 million and $11.1 million for the same period in 2021 due to increased costs associated with ongoing clinical trials evaluating fadraciclib in Phase 1/2 studies and an increase in non-clinical expenditures. R&D expenses related to plogosertib were $1.3 million and $5.5 million for the three months and year ended December 31, 2022, as compared to $1.1 million and $3.5 million for the same period in 2021 due to clinical trial costs associated with the plogosertib Phase 1/2 study. General and administrative expenses for the three months and year ended December 31, 2022, were $2.1 million and $7.4 million, compared to $1.9 million and $7.5 million for the same period of the previous year due to an increase in employment and professional costs. Total other income, net, for the three months and year ended December 31, 2022, were an expense of $0.2 million and income of $1.7 million, compared to an income of $43,000 and $0.2 million for the same period of the previous year. The increase of $1.5 million for the year ended December 31, 2022, is primarily related to royalty income. United Kingdom research & development tax credits for the three months and year ended December 31, 2022 were $1.6 million and $4.7 million compared to $1.2 million and $3.8 million for the same period of the previous year and are directly correlated to qualifying research and development expenditure. Net loss for the three months and year ended December 31, 2022, was $7.4 million and $21.2 million (including stock based compensation expense of $0.4 million and $1.5 million respectively), compared to $5.3 million and $18.9 million (including stock based compensation expense of $0.3 million and $1.2 million respectively) for the same period in 2021.
