(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 reported financial results for the second quarter ended June 30, 2025, and highlighted recent corporate progress.    “We are pleased to report continuous clinical development progress across our entire pipeline of Precision Endocrine Peptide (PEP) product candidates with a number of value-creating milestones anticipated in the second half of this year,” said Kent Hawryluk, President and Chief Executive Officer of MBX Biosciences. “We look forward to sharing topline results from our Phase 2 Avail™ trial of canvuparatide in hypoparathyroidism this quarter. In addition, we are on track to initiate a Phase 2a clinical trial for imapextide, a peptide therapy for the treatment of post-bariatric hypoglycemia, and a Phase 1 trial evaluating MBX 4291 in patients with obesity, both in this quarter.”    Second Quarter 2025 and Recent Corporate Highlights    Hypoparathyroidism (HP): Canvuparatide (MBX 2109)     Phase 2 topline data from Avail trial expected in Q3 2025. Topline results from the Phase 2 Avail trial of canvuparatide, a potential long-acting, once-weekly parathyroid hormone (PTH) peptide prodrug candidate, are on track to be reported in the third quarter of 2025.    Post-bariatric Hypoglycemia (PBH): Imapextide (MBX 1416)     Patient screening underway in Phase 2a trial: The Company has completed an end-of-Phase 1 meeting and a Phase 2a clinical trial evaluating imapextide, a long-acting glucagon-like peptide 1 (GLP-1) receptor antagonist for the treatment of PBH, is expected to begin in the third quarter of 2025.    Obesity: MBX 4291    Phase 1 trial to initiate Q3 2025: MBX 4291, a GLP-1/glucose-dependent insulinotropic polypeptide (GIP) co-agonist prodrug is being developed as a once-monthly treatment for patients with obesity. In June, the Company submitted an investigational new drug (IND) application for MBX 4291 and received clearance to proceed in July. A Phase 1 trial initiation is anticipated in the third quarter of 2025.    Corporate    Leadership team additions: In June, MBX appointed Andreas Moraitis, M.D., as Senior Vice President of Clinical Development overseeing clinical advancement of canvuparatide.    Second Quarter 2025 Financial Results    Cash and Cash Equivalents and Marketable Securities: As of June 30, 2025, MBX Biosciences had cash, cash equivalents and marketable securities of $224.9 million. Based on its current operating plan, management expects the combined cash, cash equivalents and marketable securities balance to fund operations into mid-2027.  R&D Expenses: Research and development expenses for the three months ended June 30, 2025, were $17.7 million compared to $14.4 million for the same period in 2024. The increase of $3.3 million was driven by costs associated with ongoing IND-enabling studies for MBX 4291 and the ongoing canvuparatide Phase 2 clinical trial.  G&A Expenses: General and administrative expenses for the three months ended June 30, 2025, were $4.1 million compared to $2.3 million for the same period in 2024. The increase of $1.8 million was driven by increased personnel-related costs as the Company expanded its infrastructure to support its growth in operations as a public company.  Net Loss: Net loss for the three months ended June 30, 2025, was $19.4 million compared to a net loss of $15.9 million for the same period in 2024.
