Pasithea Therapeutics Corp. (NASDAQ:KTTA) is a clinical-stage biotechnology company primarily focused on the discovery, research and development of innovative treatments for central nervous system (CNS) disorders and other diseases, including RASopathies. The company's lead therapeutic candidate, PAS-004, is a next-generation macrocyclic mitogen-activated protein kinase (MEK) inhibitor that may address the limitations and liabilities associated with existing drugs targeting a similar mechanism of action.

Business Overview

Pasithea's primary operations, the Therapeutics segment, are focused on developing PAS-004 for the treatment of a range of RASopathies, including neurofibromatosis type 1 (NF1)-associated neurofibromas, as well as certain oncology indications. In December 2023, the U.S. Food and Drug Administration (FDA) cleared the company's Investigational New Drug (IND) application for PAS-004, and Pasithea received a study may proceed letter from the FDA for a Phase 1 multicenter, open-label, dose escalation trial in patients with MAPK pathway-driven advanced tumors. The company is currently conducting this Phase 1 trial at four clinical sites in the United States and plans to open an additional three sites in Eastern Europe in the third quarter of 2024.

Pasithea's clinical development plan for PAS-004 is to begin a Phase 1 trial in adult and pediatric NF1-associated plexiform and/or cutaneous neurofibroma, with the ultimate goal of seeking FDA marketing approval in these patient populations. Additionally, the company has two discovery-stage programs, PAS-003 for amyotrophic lateral sclerosis (ALS) and PAS-001 for schizophrenia, which the company believes address limitations in the current treatment paradigm for these indications.

Financial Performance

For the fiscal year ended December 31, 2023, Pasithea reported an annual net loss of $15,961,658, with no revenue generated. The company's annual operating cash flow was -$13,425,411, and its annual free cash flow was -$13,459,712.

In the first quarter of 2024, Pasithea's net loss from continuing operations was $3,860,840, compared to a net loss from continuing operations of $3,265,810 in the first quarter of 2023, an increase of 18.2%. The company's research and development expenses increased by 59.6% to $1,749,128 in the first quarter of 2024, up from $1,096,286 in the same period of the prior year, primarily due to the initiation of the Phase 1 clinical trial for PAS-004 and related chemistry, manufacturing, and controls (CMC) activities. General and administrative expenses increased by 8.3% to $2,291,646 in the first quarter of 2024, compared to $2,116,266 in the first quarter of 2023, driven by higher legal, public company, and insurance costs.

As of March 31, 2024, Pasithea had approximately $12.0 million in cash and cash equivalents, with working capital of $10.7 million. The company's major sources of cash have been proceeds from various public and private offerings of its capital stock. Pasithea is dependent on obtaining additional working capital funding from the sale of equity and/or debt securities in order to continue executing its development plans and operations.

Liquidity and Capital Resources

Based on the company's current cash position and expected cash burn rate, management believes Pasithea will not have sufficient working capital to meet its needs through the next twelve months without raising additional capital. The company's future funding requirements will depend on the scope, timing, and results of its clinical development activities, as well as the costs of manufacturing its product candidates and preparing for potential commercialization.

Risks and Challenges

Pasithea faces several risks and challenges common to clinical-stage biotechnology companies, including the uncertainty of successfully developing and obtaining regulatory approval for its product candidates, the need for significant additional capital to fund its operations, and the potential for competition from other therapies targeting similar indications. The company also faces risks related to its reliance on third-party contract research organizations (CROs) and contract manufacturing organizations (CMOs) for the development and production of its product candidates.

Guidance and Outlook

Pasithea has not provided specific financial guidance for the 2024 fiscal year. However, the company has stated that it expects research and development expenses to increase in 2024 compared to 2023, primarily due to the ongoing clinical development of PAS-004 and related CMC activities. The company also anticipates general and administrative expenses to decrease in 2024 as compared to 2023, as it will not incur the non-recurring expenses related to the unsolicited acquisition proposal and tender offer that occurred in 2023.

Competitive Landscape

The RASopathy and CNS disorder treatment landscapes are highly competitive, with several large pharmaceutical and biotechnology companies, as well as smaller specialized firms, developing therapies targeting similar patient populations. Pasithea's success will depend on its ability to differentiate PAS-004 and its other product candidates through robust clinical data, favorable safety and efficacy profiles, and effective commercialization strategies.

Conclusion

Pasithea Therapeutics is a promising clinical-stage biotechnology company focused on developing innovative treatments for CNS disorders and RASopathies. With its lead candidate PAS-004 currently in a Phase 1 clinical trial, the company is well-positioned to potentially address significant unmet medical needs in these therapeutic areas. However, Pasithea faces the common challenges of a clinical-stage biotech, including the need for substantial additional capital and the inherent risks of drug development. Investors should closely monitor the company's progress in advancing its pipeline and managing its financial resources as it works to bring its novel therapies to market.
