Exhibit 99.1

MBX Biosciences Announces Positive Phase 1 Topline Results for MBX 1416 for the Treatment of Post-bariatric Hypoglycemia

 

Phase 1 results support proceeding to Phase 2 in patients with post-bariatric hypoglycemia (PBH), which is expected to begin in 2H 2025

Phase 1 trial in healthy volunteers showed MBX 1416 was generally well-tolerated with a favorable safety profile

Pharmacokinetic results demonstrated sustained dose-dependent exposure and support once-weekly dosing

Company to host conference call to discuss results today at 8:30 am ET

 

CARMEL, Ind., January 7, 2025 (GLOBE NEWSWIRE) -- MBX Biosciences, Inc. (Nasdaq: MBX), a clinical-stage biopharmaceutical company focused on the discovery and development of novel precision peptide therapies for the treatment of endocrine and metabolic disorders, today announced positive results from its Phase 1 single ascending dose (SAD) and multiple ascending dose (MAD) clinical trial of MBX 1416 in healthy adult volunteers. MBX 1416 is the Company’s investigational long-acting glucagon-like peptide 1 (GLP-1) receptor antagonist, being developed for the treatment of PBH.

“We are encouraged by the positive topline Phase 1 results in healthy volunteers that showed MBX 1416 was generally well-tolerated with a favorable safety profile and a promising pharmacokinetic profile supportive of once-weekly dosing,” said Kent Hawryluk, President and Chief Executive Officer of MBX Biosciences. “We also observed an apparent increase in GLP-1 peak during the first hour after a mixed meal tolerance test, which is an encouraging signal that we believe may translate into a therapeutic benefit in patients with PBH. Based on these results, we intend to initiate a Phase 2 study in patients with PBH in the second half of 2025 to further optimize dosing, pending alignment with the FDA on our proposed study design.”

 

 

Phase 1 Trial Topline Results

Key results from the study are as follows:

Phase 1 Trial Design

The Phase 1 clinical trial was a randomized, double-blind, placebo-controlled study designed to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of MBX 1416 in healthy adult volunteers. The trial was conducted in the United States and enrolled a total of 69 subjects. The single ascending dose (SAD) portion of this Phase 1 trial evaluated 32 healthy adults randomized to receive placebo (n=8) or subcutaneous MBX 1416 doses of 10 mg (n=6), 30 mg (n=6), 100 mg (n=6) and 200 mg (n=6). The multiple ascending dose (MAD) portion of the trial evaluated 23 healthy adults randomized to receive placebo (n=5) or subcutaneous MBX 1416 doses of 10 mg (n=6), 30 mg (as two injections; n=6) and 30 mg (as one injection; n=6). An additional cohort evaluated rosuvastatin and acetaminophen pharmacokinetics in the presence and absence of MBX 1416 (n=14).

MBX Biosciences intends to discuss these results with the U.S. Food and Drug Administration (FDA) in an End-of-Phase 1 meeting in mid-2025. Pending alignment with the FDA, a Phase 2 study of MBX 1416 in patients with PBH is anticipated to initiate in the second half of 2025.

MBX Biosciences will host a conference call and webcast today, January 7, 2025, at 8:30 am Eastern Time to discuss the results from the MBX 1416 Phase 1 trial. Participants can register here to access the live webcast of the conference call. Those who prefer to join the call via phone can register using this link receive a dial-in number and unique PIN. Following the live event, a replay will be available on the Investors section of the Company’s website.

 

About MBX 1416

MBX 1416 is an investigational long-acting glucagon-like peptide-1 (GLP-1) receptor antagonist in development as a potential treatment for PBH. It was designed using the Company’s novel, proprietary PEP™ platform to prevent the occurrence of severe hypoglycemia in individuals with PBH so they can lead healthier and more independent lives.

 

About Post-bariatric Hypoglycemia

Post-bariatric hypoglycemia (PBH) is a rare and serious complication of bariatric surgery. PBH is characterized by repeated episodes of symptomatic hypoglycemia, triggered by exaggerated

---

secretion of GLP-1 levels following a meal, and can present as early as six months after Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy. Hypoglycemic episodes can occur multiple times per day and can periodically manifest with severe symptoms, such as dizziness, confusion, loss of consciousness or seizure. The unpredictability of hypoglycemic episodes and their associated risks may meaningfully hinder daily activities. As a result, the patient burden can be substantial, and many individuals cannot drive, work or live alone. To date, there are no approved pharmacotherapies to treat PBH. As the use of surgery to address metabolic conditions continues to rise, the incidence of PBH is expected to increase, reinforcing the need for safe and effective therapies.

About MBX’s Proprietary Precision Endocrine Peptide (PEP™) Platform

MBX was founded by global leaders with a transformative approach to peptide drug design and development. Leveraging this expertise, the Company designed its proprietary Precision Endocrine Peptide™ (PEP™) platform to overcome the key limitations of unmodified and modified peptide therapies and to improve clinical outcomes and simplify disease management for patients. PEPs are selectively engineered to have optimized pharmaceutical properties, including extended time-action profiles and consistent drug concentrations with low peak-to-trough concentration ratios, consistent exposure to target tissues, and less frequent dosing.
