Business Overview and History

Cyclerion Therapeutics, a biopharmaceutical company focused on developing novel soluble guanylate cyclase (sGC) stimulators, has undertaken a strategic shift in recent years to navigate the evolving landscape of the biotech industry. With a diverse pipeline of products targeting both the central nervous system (CNS) and peripheral disease areas, Cyclerion has demonstrated its adaptability and commitment to advancing innovative treatments for patients.

Cyclerion was founded in 2019 as a spin-off from Ironwood Pharmaceuticals, inheriting a robust portfolio of sGC stimulator candidates. The company's initial focus was on the development of these novel therapeutics, targeting serious diseases in both the CNS and the periphery. The nitric oxide (NO)-sGC-cyclic guanosine monophosphate (cGMP) signaling pathway, which the sGC stimulators modulate, is a fundamental mechanism that precisely controls key aspects of physiology throughout the body.

In the early years, Cyclerion's pipeline included promising candidates such as praliciguat, olinciguat, zagociguat, and CY3018. Praliciguat, an orally administered, once-daily systemic sGC stimulator, was licensed to Akebia Therapeutics in 2021, securing Cyclerion the potential for up to $585 million in future milestone payments and tiered royalties.

However, in 2023, the company made a strategic decision to shift its focus towards the central nervous system (CNS) therapeutic area. As part of this transition, Cyclerion sold its zagociguat and CY3018 programs to Tisento Therapeutics, a newly formed private company, in exchange for cash, reimbursement of expenses, and an equity stake in Tisento.

The company faced challenges in 2022 and 2023, undergoing workforce reductions as part of its strategic shift. Throughout its history, Cyclerion has maintained efforts to out-license or divest its remaining sGC stimulator assets, including olinciguat, to pivot towards a new portfolio of assets. The company's strategy has evolved to focus on finding the optimal combination of capital, capabilities, and transactions to enable the advancement of current and potential future assets for the benefit of patients and shareholders.

Financials and Liquidity

Cyclerion's financial performance has been marked by a consistent focus on research and development (R&D) investments to advance its pipeline. For the fiscal year ended December 31, 2023, the company did not report revenue or net income figures. Operating cash flow and free cash flow for the year were also not disclosed.

For the most recent quarter ended September 30, 2024, Cyclerion reported total revenues of $194,000, which were derived from the option agreement for olinciguat. Research and development expenses were $81,000, and general and administrative expenses were $1.24 million. The company reported a net loss from continuing operations of $723,000 for the quarter. Operating cash flow and free cash flow for the quarter were both -$1,716,000.

As of September 30, 2024, Cyclerion had approximately $2.9 million in unrestricted cash and cash equivalents on its balance sheet. The company's current assets, including cash and cash equivalents, totaled $3.6 million, while total assets amounted to $8.9 million. The company's liabilities, primarily consisting of accounts payable and accrued expenses, totaled $0.7 million, resulting in a current ratio of 5.07 and a quick ratio of 5.07.

Cyclerion's cash position and liquidity metrics suggest that the company may need to seek additional funding to sustain its operations, as it expects to continue generating operating losses in the foreseeable future. The company's ability to generate cash from operations and access capital markets will be crucial in determining its long-term sustainability. Cyclerion expects its current cash and cash equivalents to be sufficient to fund operations into mid-2025, though it will need to obtain additional funding to sustain operations beyond that point.

The company's debt-to-equity ratio is 0, indicating no long-term debt on its balance sheet. However, Cyclerion does not disclose any information about available credit lines.

Pipeline and Strategic Transition

Cyclerion's current pipeline consists of two main assets:

1. Olinciguat: A Phase 2 orally administered, once-daily, vascular sGC stimulator that the company intends to out-license to a partner with strong cardiovascular or cardiopulmonary capabilities. In July 2024, Cyclerion entered into an Option to License Agreement with a third party, granting the Optionee the right to an exclusive license to olinciguat for human therapeutics, subject to certain carveouts. The third party paid Cyclerion an option fee of $150,000 in August 2024 and has until February 22, 2025 to exercise the option.

2. Praliciguat: An orally administered, once-daily systemic sGC stimulator. In June 2021, Cyclerion entered into a license agreement with Akebia Therapeutics, granting Akebia the exclusive worldwide rights to the development, manufacture, medical affairs, and commercialization of praliciguat and related products. Cyclerion is eligible to receive up to $585 million in total potential future development, regulatory, and commercialization milestone payments from Akebia. The company is also eligible to receive tiered, sales-based royalties ranging from single-digit to high-teen percentages, subject to reduction upon expiration of patent rights or the launch of a generic product.

The company's strategic shift towards the CNS therapeutic area has led it to actively evaluate and seek non-sGC stimulator assets within this domain. Cyclerion aims to build a new portfolio of assets, potentially through collaborations, licenses, mergers, acquisitions, or other targeted investments. The company's goal is to find the best combination of capital, capabilities, and transactions that will enable the advancement of current and future assets in a manner that maximizes shareholder value.

As part of this strategic transition, on July 28, 2023, Cyclerion sold its zagociguat and CY3018 programs, which are orally administered, CNS-penetrant sGC stimulators, to Tisento Therapeutics. In exchange, Cyclerion received $8 million in cash, $2.4 million in expense reimbursement, and a 10% equity stake in Tisento's parent company.

Risks and Challenges

Cyclerion's transition to a CNS-focused strategy comes with its own set of risks and challenges. The company's ability to identify, acquire, and successfully develop new assets within the CNS space is critical to its future success. The inherent uncertainties and high failure rates associated with drug development in the CNS domain pose significant risks.

Additionally, Cyclerion's reliance on external funding and its ability to secure necessary capital to sustain its operations represent ongoing concerns. The company's limited cash resources and the need to obtain additional financing within the next twelve months raise substantial doubt about its ability to continue as a going concern.

Furthermore, the competitive landscape in the biotech industry, regulatory uncertainties, and potential intellectual property disputes could all impact Cyclerion's ability to execute its strategy and bring new treatments to market.

The company's workforce has been significantly reduced as part of its strategic shift, with only one employee reported as of September 30, 2024. This lean structure may present challenges in terms of operational capacity and the ability to execute on its strategic objectives.

Conclusion

Cyclerion Therapeutics has demonstrated its adaptability and resilience in navigating the constantly evolving biotech landscape. The company's strategic shift towards the CNS therapeutic area represents a bold move to diversify its pipeline and capitalize on new opportunities. However, the challenges associated with this transition, including the need for additional funding and the inherent risks of drug development, will require Cyclerion to exercise prudent management and strategic decision-making to secure its long-term success.

As a small-cap company primarily operating in the United States, Cyclerion does not disclose performance by geographic markets. The company's focus on identifying and acquiring or licensing non-sGC stimulator assets, primarily in the CNS therapeutic area, reflects its efforts to build a new portfolio and maximize shareholder value. Investors will closely monitor the company's ability to identify, acquire, and advance new assets that align with its CNS-focused vision and ultimately deliver value for shareholders.
