Overview

Meribex, Inc. is a clinical-stage biopharmaceutical company focused on developing novel precision peptide therapies for endocrine and metabolic disorders. The company was founded by leaders in peptide drug design and is leveraging its proprietary Precision Endocrine Peptide (PEP) platform to overcome limitations of existing peptide therapies.

Meribex’s lead product candidate is canvuparatide, a parathyroid hormone peptide prodrug designed as a potential long-acting treatment for chronic hypoparathyroidism. The company is also advancing MBX 1416, a long-acting glucagon-like peptide-1 receptor antagonist for post-bariatric hypoglycemia, and MBX 4291, a long-acting glucose-dependent insulinotropic polypeptide receptor prodrug for obesity.

Since inception, Meribex has devoted substantial resources to research and development of its product candidates. The company has not yet generated any revenue from product sales and has incurred significant operating losses, with a net loss of $61.9 million in 2024 and an accumulated deficit of $137.5 million as of December 31, 2024. Meribex anticipates that its expenses will continue to increase as it advances its pipeline and builds commercial capabilities.

Financial Performance

Meribex’s total operating expenses were $68.2 million in 2024, up from $35.3 million in 2023. This 93% increase was driven by higher research and development (R&D) costs, which grew from $28.5 million in 2023 to $57.4 million in 2024. The company’s general and administrative (G&A) expenses also increased from $6.8 million in 2023 to $10.8 million in 2024.

The rise in R&D expenses reflects Meribex’s continued investment in advancing its lead product candidates through clinical development. Key drivers of the higher R&D costs include:

• External expenses for clinical trials, contract research organizations, and contract manufacturing
• Increased personnel and stock-based compensation costs for the R&D team
• Expanded manufacturing process development and regulatory activities

The growth in G&A expenses was primarily due to increased headcount, professional fees, and costs associated with being a public company, such as directors’ and officers’ insurance.

Despite the significant increase in operating expenses, Meribex’s net loss of $61.9 million in 2024 was partially offset by $6.3 million in net other income, primarily from interest earned on the company’s cash, cash equivalents, and marketable securities. This compares to $2.7 million in net other income in 2023.

Liquidity and Capital Resources

As of December 31, 2024, Meribex had $262.1 million in cash, cash equivalents, and marketable securities, up from $80.7 million at the end of 2023. This increase was primarily due to the $170.5 million in net proceeds from the company’s initial public offering in September 2024.

Meribex believes its current cash position will be sufficient to fund its operating expenses and capital requirements into mid-2027. However, the company expects its expenses to continue rising as it advances its pipeline and builds out commercial capabilities. Meribex may need to raise additional capital through equity offerings, debt financing, or partnerships to support its long-term growth.

Strengths and Weaknesses

Strengths:

• Proprietary PEP platform with potential to overcome limitations of existing peptide therapies
• Promising lead candidates addressing significant unmet needs in endocrine/metabolic disorders
• Experienced management team and scientific founders
• Sufficient cash runway to advance pipeline

Weaknesses:

• No approved products or revenue from product sales
• Significant accumulated losses and expectation of continued losses as expenses rise
• Reliance on external partners for manufacturing and clinical development
• Competitive landscape with approved and pipeline therapies for target indications

Outlook

Meribex is well-positioned to advance its pipeline of novel peptide therapies, with multiple clinical readouts anticipated over the next few years. The company’s lead candidate, canvuparatide, is currently in a Phase 2 trial for chronic hypoparathyroidism, with topline data expected in the third quarter of 2025.

However, Meribex will need to continue investing significantly in R&D and building commercial capabilities, which will result in ongoing losses. The company’s ability to achieve profitability will depend on the successful development and commercialization of one or more of its product candidates.

Overall, Meribex represents a promising biopharmaceutical company with a differentiated technology platform and a pipeline targeting areas of high unmet medical need. While the path to profitability will be challenging, the company’s strong cash position and experienced leadership provide a solid foundation for long-term growth.
