Biossil Pioneers AI-Driven Drug Repurposing, Secures CAD 12M with Backing from Peter Thiel and OpenAI
  • Biossil lays out a concrete path where AI, seasoned biotech talent, and strategic funding converge to accelerate repurposing drugs and delivering them to market.

  • Clinical progress includes Health Canada approving studies on Senicapoc’s effect on red blood cell breakdown and the FDA granting permission to conduct a confirmatory Rivipansel trial in the U.S., with Canada eyeing conditional approval to bring a 24-hour efficacy window drug to market.

  • The platform analyzes failed trial data and genomic databases, using graph neural networks to predict drug–target interactions and simulate over 10,000 patient profiles per hour, achieving roughly 85% accuracy in repurposing predictions.

  • Competition exists with Atomwise and BenevolentAI, but Biossil promotes cost advantages of about 30% and potential regulatory timing benefits through faster orphan-drug approvals in Canada.

  • Regulatory challenges loom as AI-generated evidence requires acceptance, with potential hybrid models that blend AI insights and traditional validation.

  • Biossil employs OpenAI language models to read public drug candidate descriptions, converts them into numerical embeddings, and maps these against disease gene data to identify repurposing opportunities.

  • The company has licensed or purchased 10 molecules, with two in advanced clinical trials and plans to seek conditional approvals to bring three repurposed drugs to market.

  • Toronto-based Biossil, using the DrugRevive platform, aims to slash the repurposing timeline by 70–80% and speed candidates into trials.

  • Founded in 2023 by Anthony Mouchantaf and Dr. Alexander Mosa, Biossil targets repurposing failed drugs with AI to uncover new therapeutic potential.

  • Key partnerships include more than 20 academic and medical institutions across North America and Europe, such as SickKids, Harvard, Mayo Clinic, and Aarhus University.

  • CEO Mina Nour leads Biossil, which has secured CAD 12 million in seed funding from investors including Golden Ventures, with notable backing from Peter Thiel and OpenAI.

  • Biossil collaborates with two major pharma companies and benefits from AI expertise linked to Google DeepMind and Pfizer, signaling strong industry interest in AI-driven repurposing.
