Metsera Unveils Promising Phase 1 Data on GLP-1 Receptor Agonist for Weight Loss

Metsera, a clinical-stage biopharmaceutical company, has announced promising results from its Phase 1 trial for MET-097, a long-acting GLP-1 receptor agonist designed for weight loss. The results indicate that MET-097 has the potential to significantly impact the obesity treatment landscape by offering an effective and convenient weight loss therapy.

Overview of MET-097 and Its Potential

The Phase 1 trial, which included 125 overweight and obese participants, demonstrated that MET-097 achieved a notable weight loss of 7.5% over a 36-day period. This result is on par or potentially better than current and investigational weight loss treatments in the GLP-1 receptor agonist category. MET-097’s effectiveness is largely attributed to Metsera’s proprietary HALO? technology, which enhances the drug’s half-life, providing long-lasting therapeutic effects and potentially reducing the frequency of dosing to once monthly or less.

Metsera’s HALO? platform technology allows for a 380-hour half-life for MET-097, making it 2-3 times longer than existing and investigational GLP-1 compounds. This extended half-life enables a more stable and sustained release of the medication, reducing the need for frequent administration and thus increasing patient compliance(Clinical Trial Vanguard ).

Key Findings from the Phase 1 Trial

The Phase 1 study was a randomized, placebo-controlled, double-blind trial designed to evaluate the safety, pharmacokinetics, pharmacodynamics, and efficacy of subcutaneous MET-097. It was administered in varying doses to healthy, non-diabetic, overweight, or obese adults. Key findings from the study include:

• Dose-Dependent Weight Loss: Participants receiving the 1.2 mg dose achieved an average weight loss of 7.5% at day 36 (one week after the final dose). This cumulative weight loss increased to 8.1% at day 57, indicating a durable pharmacodynamic effect even after the treatment period ended.
• Consistent Pharmacokinetics: The drug exhibited dose-linear pharmacokinetics, indicating consistent absorption and clearance patterns across individuals.
• Safety Profile: The adverse events were primarily mild and transient gastrointestinal issues, which were consistent with other GLP-1 receptor agonists on the market. Importantly, there were no severe adverse events or treatment-related discontinuations, highlighting a favorable safety profile.

The HALO? Technology Advantage

Metsera’s HALO? platform underpins the unique properties of MET-097. This proprietary technology enhances peptide lipidation, which not only prolongs the drug’s half-life but also improves its stability and potency. Such advancements position MET-097 as a potential next-generation weight loss treatment that can be administered without the need for complex titration. This is a key advantage over many current therapies, which require gradual dose escalation to minimize gastrointestinal side effects(BioSpace )(Clinical Trial Vanguard ).

Implications for the Weight Loss Market

The global weight loss market is highly competitive, with many established and emerging therapies vying for market share. MET-097’s promising Phase 1 results suggest that it could address several unmet needs in this space, particularly by offering:

• Once-Monthly Dosing: Unlike many other GLP-1 receptor agonists that require weekly or even daily administration, MET-097’s extended half-life could enable monthly or less frequent dosing, significantly reducing the burden of frequent injections on patients.
• No Titration Requirement: Many GLP-1 therapies require careful titration to mitigate adverse gastrointestinal effects, which can complicate treatment. MET-097’s favorable safety profile and predictable pharmacokinetics suggest it could be used without the need for complex dose adjustments.
• Sustained Efficacy: The sustained weight loss observed up to four weeks post-treatment suggests that MET-097 could maintain its therapeutic benefits over longer intervals, making it a highly convenient and effective option for chronic weight management(

Next Steps for MET-097

Following the successful completion of Phase 1, Metsera plans to initiate a Phase 2b trial in the fourth quarter of 2024, with results expected by mid-2025. This next stage will aim to further validate MET-097’s efficacy, safety, and dosing regimen, while also exploring its potential in a broader patient population. If these trials are successful, MET-097 could become a cornerstone therapy in the fight against obesity and related metabolic disorders(BioSpace )(Clinical Trial Vanguard ).

Looking Forward: Impact on Obesity Treatment

Obesity is a growing health crisis worldwide, affecting millions and contributing to the development of numerous chronic diseases such as type 2 diabetes, cardiovascular disease, and certain cancers. Effective treatments that are easy to use, have fewer side effects, and promote sustained weight loss are urgently needed.

MET-097’s unique profile positions it well to meet these needs. As a once-monthly injectable therapy that does not require titration, it has the potential to simplify weight loss treatment, improve patient adherence, and achieve meaningful and durable outcomes. With these characteristics, MET-097 could provide an attractive alternative to both existing GLP-1 receptor agonists and other emerging therapies.

About Metsera: Driving Innovation in Weight Loss

Founded in 2022 and backed by leading investors, Metsera is dedicated to advancing innovative therapies for obesity and metabolic diseases. In addition to MET-097, Metsera is developing a diverse portfolio of oral and injectable treatments aimed at addressing the evolving needs of patients in this therapeutic area. The company’s strategic focus is on harnessing cutting-edge science to produce next-generation therapies that offer improved efficacy, safety, and convenience.

With Phase 2 trials on the horizon and a promising initial safety and efficacy profile, MET-097 has the potential to become a major player in the GLP-1 receptor agonist market. If successful, Metsera’s approach could reshape the obesity treatment landscape, providing hope to millions of individuals striving for better health outcomes(BioSpace )(Clinical Trial Vanguard ).

Final Thoughts

Metsera’s early-phase results for MET-097 suggest that the company is on the path to developing a truly transformative weight loss therapy. By leveraging its HALO? technology, Metsera has created a GLP-1 receptor agonist that combines long-lasting efficacy with a simplified dosing regimen. As obesity rates continue to climb, the need for innovative solutions like MET-097 is more critical than ever. The upcoming Phase 2b trials will be crucial in determining whether this promising candidate can deliver on its potential and make a real difference in the lives of patients.
