Key takeaways
- The company is focused on LTIO3, a novel drug for idiopathic pulmonary fibrosis (IPF) with a dual mechanism: inhibiting pro-fibrotic proteins and preserving type 2 epithelial progenitor cells that can regenerate lung tissue.
- LTIO3 is currently in a phase 2 clinical trial for IPF, with enrollment progressing faster than expected, reaching over 25%.
- Two prior clinical trials were completed: a phase 1A in healthy volunteers and a phase 1B in IPF patients, demonstrating safety and lung-specific biomarker effects.
- The drug mimics cabulin-1, a protein lost in fibrotic states, restoring its regulatory function across multiple fibrotic pathways.
- In ex vivo studies using lung tissue from IPF patients, LTIO3 showed inhibition of pro-fibrotic proteins comparable to the market-leading drug Ofev but without associated toxicity.
- LTIO3 uniquely preserves and increases viability of lung progenitor cells, a feature not seen with other treatments.
- Clinical biomarker data showed significant reductions in several pro-fibrotic proteins in IPF patients' lungs and a 5% reduction in plasma surfactant protein D after two weeks of dosing, comparable to reductions seen with approved drugs over 12 weeks.
- IPF affects approximately 100,000 people in the US annually with about 50,000 new cases and deaths each year, and current approved drugs only slow disease progression with severe side effects and high discontinuation rates.
- The phase 2 study is placebo-controlled with two doses (5 mg and 10 mg daily) over 24 weeks, measuring forced vital capacity (FVC) and high-resolution CT scans analyzed by AI imaging.
- The company has a small expert team including Dr. Corey Hogaboom, a leading IPF researcher who joined as Chief Scientific Officer after validating the drug’s unique regenerative effects.
