CARMEL, Ind., Nov. 07, 2024 (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 reported financial results for the third quarter ended September 30, 2024, and highlighted recent progress.
“The third quarter of 2024 has been transformational for MBX, as we transitioned to a publicly traded company and advanced our clinical-stage precision peptide programs,” said Kent Hawryluk, President and Chief Executive Officer of MBX Biosciences. “Our team is committed to delivering on our upcoming clinical milestones, including completion of the last subject visit in the Phase 1 trial of MBX 1416 anticipated by late November, and we expect to report top line results for this trial in early January 2025. In addition, enrollment in the Phase 2 trial of MBX 2109 in patients with hypoparathyroidism is on track to be complete in the first quarter of 2025, and we continue to expect topline results in the third quarter of 2025. The capital raised in our initial public offering in September and our Series C financing in August enables us to execute on these clinical milestones and advance the development of our early-stage pipeline programs, including our obesity portfolio, as we aim to overcome limitations of current therapies and improve the standard of care.”
Third Quarter 2024 and Recent Business Highlights
MBX 2109
Presented the rationale and design of the Phase 2 Avail™ trial of MBX 2109: In September 2024, the Phase 2 Avail trial of MBX 2109, the Company’s potential long-acting parathyroid hormone (PTH) peptide prodrug, in adults with hypoparathyroidism (HP) was featured in a poster presentation at the American Society for Bone and Mineral Research 2024 Annual Meeting held in Toronto, ON, Canada.
Initiated Phase 2 Avail trial of MBX 2109: In August 2024, the Company announced that the first patient was dosed in the Phase 2 Avail trial of MBX 2109. Enrollment is expected to complete in the first quarter of 2025 with topline results expected in the third quarter of 2025.
MBX 1416
Last Subject Last Visit in MBX 1416 Phase 1 trial anticipated by late November 2024: MBX expects the last subject visit to be completed by the end of November in the Phase 1 single and multiple ascending dose trial of MBX 1416, the Company’s long-acting glucagon-like peptide 1 (GLP-1) receptor antagonist in development for the treatment of post-bariatric hypoglycemia. The Company plans to announce topline results in early January 2025.
MBX 4291
Progressing MBX 4291 IND-enabling studies: MBX is in the process of completing investigational new drug (IND) enabling studies for its GLP-1/GIP co-agonist prodrug MBX 4291 for the potential treatment of obesity and expects to submit an IND application to the U.S. Food and Drug Administration in the second quarter of 2025. The Company also has additional programs in the lead optimization stage of development for the treatment of obesity and associated comorbidities.
Corporate
Completed upsized initial public offering (IPO) and Series C financing: In September 2024, MBX completed its IPO following its Series C financing in August. Total gross proceeds from the Initial Public Offering and Series C financing were approximately $251.2 million.
Third Quarter 2024 Financial Results
Cash and Cash Equivalents and Marketable Securities: As of September 30, 2024, MBX had cash, cash equivalents and marketable securities of $277.1 million compared to $80.7 million as of December 31, 2023. 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 September 30, 2024, were $16.7 million compared to $9.1 million for the same period in 2023. The increase of $7.7 million was driven by costs associated with ongoing IND-enabling studies for MBX 4291 and the ongoing MBX 2109 Phase 2 clinical trial.
G&A Expenses: General and administrative expenses for the three months ended September 30, 2024, were $2.9 million compared to $1.9 million for the same period in 2023. The increase of $1.0 million was driven by increased personnel-related costs as the Company expanded its infrastructure to support its growth in operations.
