AOI Biosciences' Roughly 500 Million Yen Financing and Share Transaction of 14 September 2026 Lists Its Neo-Self Antibody Test Ahead of the Toshiba SQBM+ Quantum-Inspired Drug Platform

Evidence-based insights for quantum medicine.

On 14 September 2026 AOI Biosciences, a diagnostics and drug-discovery company in Ibaraki, Osaka Prefecture, announced a financing and secondary-share transaction of roughly 500 million yen with existing and new investors; the company says the new-share portion takes its cumulative funding to about 1 billion yen, and it does not state how much of the 500 million is new money. The release describes two core businesses. One is a blood test for a "neo-self" autoantibody that is already sold to more than 300 Japanese medical institutions. The other is an allosteric drug-discovery method built with Toshiba on the quantum-inspired SQBM+ solver, the method whose patent Toshiba announced on 3 September and this Monitor examined on 6 September.

The release lists three planned uses for the proceeds, and that list is the useful fact for a hospital buyer or a pharma partner, with one caution: the order says nothing about how much money goes where or which business the company values more. The neo-self antibody test fills the first two entries, with domestic roll-out, Asian expansion and new autoimmune indications, and further research investment in the quantum-inspired drug discovery platform is the third. No amounts are attached to any entry. The clinical figures the release cites for the test, a pregnancy rate more than doubled and a live-birth rate 1.7 times higher, come from two Frontiers in Immunology cohort studies whose treated and untreated groups can be counted, and this note counts them.
