Company Overview

Cyclacel Pharmaceuticals, Inc. (NASDAQ:CYCC) is a clinical-stage biopharmaceutical company dedicated to developing innovative cancer medicines based on cell cycle, transcriptional regulation, epigenetics, and mitosis control biology. With a strong focus on precision medicine, Cyclacel is leveraging its deep understanding of cancer biology to advance its lead candidate, fadraciclib, and its PLK1 inhibitor, plogosertib, through strategic clinical trials.

History and Development

Cyclacel's origins can be traced back to 1996, when it was founded as Xcyte Therapies, Inc. in Seattle, Washington. The company initially focused on the development of adoptive cellular immunotherapy for the treatment of cancer. In 2006, Xcyte Therapies merged with Cyclacel Limited, a biopharmaceutical company based in Dundee, Scotland, and the combined entity was renamed Cyclacel Pharmaceuticals, Inc. This strategic merger allowed Cyclacel to expand its pipeline and expertise in cancer cell cycle regulation.

The company faced a significant setback in 2012 when it discontinued its operations after failing to meet primary endpoints in a Phase 3 trial of its lead product candidate at the time. This challenge forced Cyclacel to reevaluate its strategy and refocus its efforts. In the following years, the company worked diligently to rebuild and reposition itself as a pioneer in the field of cancer cell cycle biology. Cyclacel acquired new intellectual property and developed a pipeline of novel therapeutic candidates, including fadraciclib and plogosertib.

In 2017, Cyclacel achieved a key milestone by completing a public offering that provided necessary capital to advance its clinical programs. This influx of funds allowed the company to progress its research and development efforts. In 2020, Cyclacel initiated a Phase 1/2 study evaluating fadraciclib in advanced solid tumors and lymphomas, marking another important step in the company's journey.

Product Pipeline

Over the years, Cyclacel has developed a robust portfolio of clinical-stage assets, with fadraciclib and plogosertib being the company's primary focus. The company's product pipeline is divided into two main segments: the Transcriptional Regulation Program and the Anti-Mitotic Program.

Transcriptional Regulation Program: Fadraciclib, an oral CDK2/9 inhibitor, is the lead candidate in this program. It is currently being evaluated in a Phase 2 proof-of-concept study (CYC065-101) for patients with advanced solid tumors and lymphoma. The study is specifically targeting patients with CDKN2A and/or CDKN2B genetic alterations, which are commonly found in various solid tumors and certain T-cell lymphomas. Preliminary data from the Phase 2 portion of the CYC065-101 study, presented at the 2024 EORTC-NCI-AACR Symposium, showed that fadraciclib was well-tolerated and demonstrated signs of clinical activity in this biomarker-enriched patient population.

In the Phase 1 part of the study, 47 heavily pretreated patients were dosed across 8 dose levels. Fadraciclib was generally well-tolerated, with partial responses observed in patients with T-cell lymphoma and solid tumors, including non-small cell lung cancer, endometrial, ovarian, and pancreatic cancers. The Phase 2 part of the study is ongoing, with two dose expansion cohorts enrolling patients with CDKN2A/B alterations and T-cell lymphoma to further evaluate the observations from Phase 1.

Anti-Mitotic Program: Plogosertib, Cyclacel's PLK1 inhibitor, is the focus of this program. It is being investigated in a Phase 1/2 registration-directed study (CYC140-101) for the treatment of advanced solid tumors and lymphoma. This open-label study is designed to determine the recommended Phase 2 dose (RP2D) and to evaluate the efficacy of plogosertib in mechanistically relevant cohorts, including patients with bladder, breast, colorectal, hepatocellular, biliary tract, and lung cancers, as well as lymphomas. Fifteen patients have been treated in the dose escalation part of the study so far, with stable disease observed in some heavily pretreated patients.

Financials

Cyclacel's financial position has seen some challenges in recent years. In the fiscal year 2023, the company reported revenue of $420,000 and a net loss of $22,555,000. The operating cash flow (OCF) for 2023 was -$16,112,000, and the free cash flow (FCF) was -$16,118,000.

For the third quarter of 2024, Cyclacel reported revenue of $10,000, compared to $16,000 in the same period of 2023, representing a 37.5% decrease. This decline was due to the completion of obligations under an investigator-sponsored study managed by Cedars-Sinai Medical Center. The net loss for Q3 2024 was $1,957,000, a significant improvement from the $6,030,000 loss in Q3 2023. The company's OCF and FCF for Q3 2024 were both positive at $3,560,366.

Research and development (R&D) expenses have fluctuated in recent years, reflecting the company's strategic focus on its lead programs. In 2023, R&D expenses decreased to $19.2 million, compared to $20.3 million in 2022, primarily due to a reduction in clinical trial and non-clinical expenses related to fadraciclib and plogosertib. In Q3 2024, R&D expenses further decreased to $950,000, down from $5.2 million in the same quarter of 2023, reflecting a reduction in clinical trial and non-clinical expenditures.

General and administrative (G&A) expenses remained relatively flat at $6.7 million in 2023 and 2022, with a slight decrease of $0.3 million reported in the latest quarter.

Liquidity

The company's liquidity position has been a point of concern. As of September 30, 2024, Cyclacel had cash and cash equivalents of $2.98 million, a significant decrease from $18.3 million at the end of 2022. The company's management has acknowledged the substantial doubt about Cyclacel's ability to continue as a going concern, and they are actively exploring options to raise additional capital through private equity financing or strategic transactions.

Cyclacel's debt-to-equity ratio stood at 0.061 as of December 31, 2023. The company's current ratio and quick ratio were both 0.77 as of the same date, indicating potential liquidity challenges. Cyclacel has not disclosed any available credit lines.

The company estimates that its current cash resources will fund planned programs into the fourth quarter of 2024. Management is focused on carefully managing resources to ensure the continued advancement of its clinical programs. Cyclacel's ability to regain compliance with Nasdaq's minimum stockholders' equity requirement by the end of 2024 will be a critical milestone for the company.

Future Outlook

Despite the financial challenges, Cyclacel remains focused on advancing its pipeline of innovative cancer therapies. The company's precision medicine approach, targeting specific genetic alterations in cancer cells, has shown promise in its ongoing clinical studies.

For the Fadra Phase 2 proof-of-concept study, Cyclacel is recruiting well and expects to report initial results from around a dozen patients by the end of 2024. The success criteria for the first part of the study is to see at least two responses in the first 12-14 patients. If successful, the company plans to move on to confirm the dose response in larger cohorts.

Cyclacel's ability to navigate the regulatory landscape and secure the necessary funding will be crucial in determining the future success of its therapeutic candidates. The company's management team is actively exploring ways to strengthen its financial position and advance its clinical programs.

In conclusion, Cyclacel Pharmaceuticals is a clinical-stage biopharmaceutical company that is leveraging its deep understanding of cancer biology to develop innovative cancer therapies. While the company has faced financial challenges in recent years, its strategic focus on precision medicine and the continued advancement of its lead programs, fadraciclib and plogosertib, remain promising. Cyclacel's ability to raise additional capital and regain compliance with Nasdaq's listing requirements will be critical in determining the company's long-term trajectory.
