Trontinemab (development codes RG6102 / RO7126209) is a 2+1 bispecific molecule: it fuses the amyloid-beta-clearing antibody gantenerumab to a fragment that grabs transferrin receptor 1 (TfR1) on blood-brain-barrier cells, hitching a ride into the brain via the same receptor-mediated transport that carries iron. That shuttle lets a low intravenous dose clear amyloid plaques rapidly and deeply while triggering strikingly little of the brain swelling and micro-bleeding (ARIA) that limits approved anti-amyloid drugs. In the Phase Ib/IIa Brainshuttle AD study (NCT04639050), the 3.6 mg/kg dose removed roughly 107 centiloids of amyloid after 28 weeks, driving about 91-92% of participants below the amyloid-positivity threshold (24 centiloids) - with ARIA-E seen in fewer than 5% of participants, well below the ~13% reported for lecanemab and ~24% for donanemab. On the strength of those data, Roche launched two identical pivotal Phase 3 trials - TRONTIER 1 and TRONTIER 2 - in early symptomatic Alzheimer's disease (about 1,600 patients across 18 countries, begun in 2025), and at the 2026 Alzheimer's Association International Conference (AAIC) in London it unveiled PrevenTRON, a Phase 3 prevention trial in 1,600 cognitively unimpaired people at high risk (elevated plasma p-tau217). Trontinemab is a prescription-stage investigational biologic - it is not approved anywhere and is not a supplement or research chemical.

It is the follow-on to donanemab (Kisunla), Lilly's FDA-approved anti-amyloid antibody that hits the same target, and is designed to clear existing brain amyloid rapidly and, distinctively, to be delivered by a short subcutaneous injection that patients or care partners can give at home rather than only by intravenous infusion in a clinic. In an early-phase study three-quarters of treated participants reached the amyloid-clearance threshold within about six months, and remternetug is now in Phase 3 across symptomatic early Alzheimer's (TRAILRUNNER-ALZ 1), a large prevention program (TRAILRUNNER-ALZ 3), and inherited-Alzheimer prevention through the DIAN-TU network. It is not approved by the FDA or any regulator for any use.
