Steel Therapeutics (搜索)' mission focuses on scaling access to compounded drugs with proven safety and effectiveness track records, particularly in the gastrointestinal space. The company's team of pharmacist-founders brings direct experience from building and operating retail compounding programs, positioning them to identify high-impact drug candidates and innovative delivery systems.
Regulatory Pathway and Next Steps
The GLP-compliant toxicology study was conducted at Altasciences (搜索)' nonclinical research facility in Columbia, Missouri, leveraging the organization's expertise in toxicology, regulatory-supportive safety assessments, and integrated drug development services. The teams at Altasciences and Steel Therapeutics (搜索) worked closely together to efficiently execute the program and maintain momentum toward key development milestones.
