Product Candidates - Canvuparatide, the lead product candidate, is designed for once-weekly administration to treat chronic hypoparathyroidism, with Phase 2 topline data expected in Q3 2025[23]. - MBX 1416, a long-acting GLP-1 receptor antagonist, aims to address post-bariatric hypoglycemia, with a Phase 2 trial initiation planned for the second half of 2025[23]. - MBX 4291, a GLP-1/GIP co-agonist prodrug for obesity, has shown potential for once-monthly administration and is expected to submit an IND in Q2 2025[30]. - Canvuparatide demonstrated a low peak-to-trough ratio in Phase 1 trials, supporting its potential as a continuous infusion-like therapy[32]. - Canvuparatide, the lead product candidate, is designed for once-weekly administration and has demonstrated a low peak-to-trough ratio in Phase 1 trials, potentially enabling the first once-weekly PTH dosing regimen for patients with chronic hypoparathyroidism (HP)[45]. - The ongoing Avail™ Phase 2 clinical trial involves 64 patients and aims to evaluate the efficacy of canvuparatide over a 12-week period, with a primary endpoint of discontinuing active vitamin D and reducing calcium supplements[71]. - MBX 1416 is a long-acting GLP-1 receptor antagonist designed to prevent severe hypoglycemia in patients with PBH, with a potential for once-weekly administration[87]. - The obesity portfolio includes MBX 4291, a long-acting GLP-1/GIP receptor co-agonist prodrug, with IND submission anticipated in Q2 2025[108]. Market Opportunity - The company estimates that chronic hypoparathyroidism affects over 250,000 people in the U.S. and Europe, while post-bariatric hypoglycemia affects more than 90,000 people in the U.S.[32]. - The global sales of peptide-based therapies exceeded $50 billion in 2019, indicating a significant market opportunity for the company's products[35]. - The obesity market presents a significant commercial opportunity, with an estimated 190 million adults in the U.S. classified as obese or overweight[109]. - Current GLP-1-based therapies require weekly injections and can cause significant gastrointestinal side effects, highlighting the need for better-tolerated alternatives[113]. Technology and Development - The PEP platform is engineered to provide peptides with extended time-action profiles and low peak-to-trough ratios, enhancing efficacy and tolerability[25]. - The PEP platform includes advanced chemical modifications and programmable prodrug technologies aimed at improving stability, solubility, and clinical outcomes[28]. - The company has developed significant know-how in creating proprietary PEPs with novel mechanisms of action and enhanced pharmacokinetic profiles[42]. - Canvuparatide incorporates programmable prodrug technology and fatty acylation to achieve sustained PTH peptide levels and convenient dosing[51]. - The design of MBX 4291 incorporates prodrug and fatty acylation mechanisms to extend its time-action profile, potentially allowing for improved tolerability and weight loss outcomes[116]. Clinical Trials and Results - The FDA has granted Orphan Drug Designation to canvuparatide for the treatment of HP, with enrollment in the Phase 2 clinical trial completed in March 2025 and topline data expected in Q3 2025[45]. - In Phase 1 clinical trials, canvuparatide was well-tolerated with no severe drug-related adverse effects, and hypercalcemia was observed in 3 subjects at higher doses[59]. - The half-life of canvuparatide was approximately 7.7 to 8.9 days, supporting a once-weekly dosing regimen[60]. - Maximal increases in serum calcium levels were observed approximately 48 hours after canvuparatide injections, with nearly maximal effects after the third weekly injection[63]. - Phase 1 clinical trial results indicated that MBX 1416 was generally well-tolerated, with no dose-related serious adverse events and injection site reactions resolving within about seven days[96]. - The pharmacokinetic data showed that MBX 1416 achieved a median half-life of approximately 90 hours, supporting once-weekly dosing, with steady state reached by the third dose[97]. Competitive Landscape - Direct competitors for HP include Ascendis Pharma and AstraZeneca, while competitors for PBH include Xeris Pharmaceuticals and Amylyx Pharmaceuticals[134]. - Eli Lilly and Company has several obesity compounds in development, including tirzepatide, which is expanding indications and labeling, and Orforglipron, currently in Phase 3 trials[136]. - Novo Nordisk received FDA approval on March 8, 2024, for semaglutide to reduce the risk of heart attacks, strokes, and cardiovascular-related death in overweight or obese patients with heart disease[136]. - Amgen is developing MariTide/AMG-133, a potential once-monthly injectable currently in Phase 2 clinical development[136]. - Pfizer is developing danuglipron, a potential twice-daily oral GLP-1 receptor agonist currently in Phase 3 clinical development[136]. - Zealand Pharma is developing Survodutide, a long-acting once-weekly injectable GLP-1/glucagon receptor co-agonist currently in Phase 3 clinical development[136].
