Mbx Biosciences(NASDAQ) MBX

MBX makes new medicines for people with hormone and metabolic problems. They design treatments that last longer to reduce the number of shots patients need. These therapies help patients manage chronic conditions with more stable levels of medicine in their blood.

Medicines for Hormone Balance

• Hypoparathyroidism Therapy: Canvuparatide is a once-weekly injection designed to replace parathyroid hormone, which controls calcium levels in the body.
• Obesity Treatment: MBX 4291 is a potential once-monthly injection that targets two different hormones to help with weight loss.
• Hypoglycemia Solution: Imapextide is a once-weekly therapy aimed at preventing dangerously low blood sugar after weight-loss surgery.

From Lab to Clinic

• Entered an exclusive license agreement with Indiana University Research and Technology Corporation in 2020 to develop its core peptide technologies.
• Completed an End of Phase 2 meeting with the FDA in 2025 to prepare for a Phase 3 study of its lead hormone replacement drug.
• Expanded its pipeline by starting Phase 1 clinical trials for its obesity candidate, with more results expected in late 2026.
• Initiated the STEADI Phase 2a clinical trial to evaluate how well its hypoglycemia drug works in adult patients.

The Precision Advantage

MBX uses its PEP platform to create "prodrugs" that slowly turn into active medicine inside the body. This approach provides steady drug levels and helps avoid the side effects often caused by traditional peptide injections.
