MBX Biosciences, Inc. experienced a remarkable surge in its stock price during premarket trading on Monday, following the release of promising results from its Phase 2 trial of canvuparatide for chronic hypoparathyroidism. As enthusiastically stated in the publication, the stock soared by 139.10%, reaching $23.91, a significant leap from its previous close of $10.00 on Friday.
Phase 2 Avail Trial Results
The Phase 2 Avail trial results showcased the drug's efficacy, with 63% of patients receiving canvuparatide meeting the primary composite endpoint at 12 weeks, compared to only 31% in the placebo group. This outcome not only surpassed expectations but also demonstrated statistical significance without any reliance on rescue therapy, underscoring the drug's effectiveness as a standalone treatment.
Patient Participation and Open-Label Extension
All 64 participants completed the 12-week study, with an impressive 94% opting to continue into the open-label extension phase, reflecting strong patient confidence in the treatment. The open-label results were even more promising, with 79% of patients achieving responder status at the six-month mark. Additionally, the drug positively impacted bone and kidney biomarkers, showing increased bone turnover markers and a significant reduction in urine calcium levels among treated patients.
Safety Profile and Investor Optimism
The safety profile of canvuparatide remained favorable throughout the trial, with the drug being well-tolerated across all doses. This premarket stock surge highlights investor optimism regarding canvuparatide's potential as a leading treatment for hypoparathyroidism, a rare endocrine disorder affecting over 250,000 individuals in the US and Europe. With a market capitalization of $33.594 million, MBX is well-positioned for the anticipated Phase 3 trial set to begin in 2026, as current treatments primarily rely on high doses of oral calcium and vitamin D supplements, which do not address the underlying PTH deficiency. The company is also preparing to present additional trial data at an upcoming medical meeting.
