- Your trial benefits from decades of experience and extensive prior data
Our Motivation
- More than 500 million people world-wide live with osteoarthritis (OA), a major cause of pain and disability
- No approved drug (DMOAD) therapy currently exists for effectively modifying joint structural pathology in OA
- To provide imaging biomarkers that accelerate your clinical development program of disease-modifying therapy
Our Expertise
- Class IIa Medical Device software platform (EU MDR 2017/745, Annex IX)
- EN ISO 13485:2021 certified QMS, compliant with GCP, 21 CFR Part 11, and relevant industry standards
- 200+ journal publications & 40.000+ citations (HF > 100)
- Regulatory compliance for your trial
Competitive Edge
- 20+ years industry expertise
- Strong SAB of OA experts
- Quality-controlled manual gold-standard and technically/clinically validated, fully automated segmentation, using AI (CNN) technology
- Scalable automated analysis for your trial, with economic benefits
Our Vision
- To establish imaging biomarkers as regulatory-accepted surrogate endpoints of clinical outcomes
- To establish AI-powered automated analysis of joint tissues & responsive measures of structural pathology
- To advance quantitative imaging to make your clinical trials efficient, meaningful, and cost-effective
Our biomarker portfolio
- Cartilage morphology (e.g. thickness)
- Cartilage composition (e.g. T2)
- Meniscus morphology & position
- Bone, muscle & adipose tissue morphology
- Infrapatellar fat pad (IPFP) radiomics
- (Effusion) synovitis morphology
