BERKELEY HEIGHTS, N.J., Aug. 10, 2022 (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 second quarter 2022 financial results and provided a business update.

“In the first half of 2022 we have established that oral fadraciclib, our CDK2 and CDK9 inhibitor, is well-tolerated and demonstrated single-agent, anticancer activity across multiple solid tumor and lymphoma patients in our 065-101 study,” said Spiro Rombotis, President and Chief Executive Officer of Cyclacel. “In the second half of 2022 we are optimizing the dosing schedule to maximize target coverage and determine recommended Phase 2 dose (RP2D). We then anticipate advancing into Phase 2 proof of concept stage of 065-101. We believe that daily dosing of oral fadraciclib targeting both CDK2 and CDK9 at efficacious doses without dose limiting toxicities may represent best-in-class properties. We look forward to reporting additional clinical and preclinical data at our upcoming R&D Day for both fadraciclib and CYC140, our differentiated PLK1 inhibitor, also in a Phase 1/2 study.”

“We are excited with the progress of oral fadraciclib in our Phase 1/2 solid tumor and lymphoma study because of the promising safety and early efficacy results we are seeing in a challenging Phase 1 population,” said Mark Kirschbaum, M.D., Chief Medical Officer of Cyclacel. “As fadraciclib has been relatively well tolerated, 065-101 principal investigators agreed to continue dose escalation with the current 4-week schedule. Following Food and Drug Administration (FDA) clearance of a protocol amendment, we are recruiting patients at the sixth dose level of 065-101. We have previously observed partial response and anticancer activity including tumor shrinkage in endometrial, lymphoma and pancreatic cancer patients. In parallel we are determining which tumor types to prioritize for the Phase 2 stage of 065-101 informed by preclinical modeling and data from our clinical collaborators. The 065-102 study of fadraciclib in advanced leukemias continues to enroll at the 100mg twice a day dose level after clearance of a protocol amendment that allowed us to skip two dose levels. We are also encouraged that the 140-101 dose escalation study of CYC140 is now recruiting patients with solid tumors and lymphomas for the second dose level.”

Key Highlights

  • Oral fadraciclib 065-101 Phase 1/2 study in advanced solid tumors: The study has enrolled seventeen patients with advanced solid tumors and lymphomas treated with oral fadraciclib up to dose level five (100mg dosed twice daily, 4 weeks out of 4) with no-dose limiting toxicities observed thus far. Following recent FDA clearance to escalate, two additional, higher dose levels will be evaluated before determining recommended Phase 2 dose. Dose level six is now recruiting.

Summary of key efficacy, safety and PK findings to date:

  • A cutaneous T cell lymphoma (CTCL) patient achieved partial response (PR) in the first oral treatment cycle.
  • A patient with a very aggressive form of peripheral T cell lymphoma (PTCL) achieved 38% reduction in target lesions by PET scan in the first oral treatment cycle.
  • An endometrial cancer patient achieved stable disease with 15% reduction of target lesions after the first oral treatment cycle. In an earlier study of intravenous fadraciclib as monotherapy, a patient with MCL1 amplified endometrial cancer achieved confirmed complete response (CR) and remains on study after two and a half years of treatment.
  • A pancreatic cancer patient achieved stable disease by confirmatory scan for five oral treatment cycles.
  • No dose limiting toxicities have been observed at any of the five dose levels evaluated thus far. The FDA has cleared a protocol amendment to escalate to two additional dose levels; dose level six at 150mg and dose level 7 at 200mg twice daily.
  • Demonstrated evidence of target engagement for CDK2 and CDK9 in cell assay systems; patient PK data suggested that these targets are potentially inhibited at 100mg twice daily levels.

The 065-101 study is enrolling at four sites. Several additional sites are in start-up preparations to join the Phase 2 proof-of-concept stage of this registration-directed study. The Phase 2 part of 065-101 includes seven histologically defined cohorts thought to be sensitive to the drug’s mechanism: breast, colorectal (including KRAS mutant), endometrial/uterine, hepatobiliary, ovarian cancers and lymphomas. The study also includes an eighth basket cohort which will enroll patients regardless of histology with biomarkers relevant to the drug’s mechanism, including MCL1, MYC and/or cyclin E amplified.

  • Oral fadraciclib 065-102 Phase 1/2 study in leukemias or myelodysplastic syndromes: Based on good tolerability in the 065-101 study, FDA clearance of a protocol amendment in the 065-102 study has accelerated dose progression by omitting dose levels two and three and now enrolling at dose level four.

    In April, the Company announced a publication in the journal, Leukemia, confirming fadraciclib suppresses MCL1 and synergizes with venetoclax in chronic lymphocytic leukemia. Results from the study confirmed that fadraciclib inhibited CDK9-mediated transcription, reduced levels of the short-lived, anti-apoptotic protein MCL1, and induced apoptosis in primary CLL cells. The data highlighted the importance of continuous treatment to prevent recovery of MCL1 protein levels. Furthermore, fadraciclib was shown to combine synergistically with the BCL2 antagonist, venetoclax, and demonstrated even greater synergy when targeted against 17p deleted CLL cells which were not sensitive to either agent alone.
  • Oral CYC140 140-101 Phase 1/2 study in solid tumors and lymphomas: The registration-directed, Phase 1 dose escalation stage of this study is enrolling patients at dose level two.

Summary of key efficacy, safety and PK findings to date:

  • No dose limiting toxicities observed to date.
  • An ovarian cancer patient in 140-101 achieved stable disease with tumor shrinkage after the first treatment cycle and is continuing treatment on cycle three.

The study uses a streamlined design and will initially determine RP2D for single-agent oral CYC140. Following RP2D, the trial will immediately enter into proof-of-concept, cohort stage, using a Simon 2-stage design. In this stage CYC140 will be administered to patients in up to seven mechanistically relevant cohorts including patients with bladder, breast, colorectal (including KRAS mutant), hepatocellular and biliary tract, and lung cancers (both small cell and non-small cell), as well as lymphomas plus an eighth basket cohort which will enroll patients with biomarkers relevant to the drug’s mechanism.
