BioArctic + Eli Lilly Sign BrainTransporter Neurodegeneration Collaboration — $30M Upfront, Up to $770M Milestones + Mid-Single-Digit Royalties — Lilly's Fourth Blood-Brain-Barrier Bet After Alzheimer's Programs
BioArctic (Nasdaq Stockholm: BIOA b) announced on June 22, 2026 a research and collaboration agreement with Eli Lilly combining BioArctic's proprietary BrainTransporter technology — transferrin-receptor-mediated active transport across the blood-brain barrier — with an undisclosed Lilly proprietary molecule in neurodegeneration. BioArctic receives $30M upfront, eligibility for milestone payments up to $770M (total potential value ~$800M), plus tiered mid-single-digit royalties on global net sales. BioArctic will generate the new drug candidate combining the technology with Lilly's molecule; Lilly assumes full global development and commercialization responsibility. This is BioArctic's fourth BrainTransporter partnership, after collaborations with Bristol Myers Squibb (Alzheimer's), AbbVie, and an undisclosed partner. The deal signals continued big-pharma demand for blood-brain-barrier delivery platforms as neurodegeneration competition intensifies post-leqembi.
