Milestone strengthens manufacturing flexibility and supports pivotal study readiness
BURLINGTON, Mass, Aug. 12, 2026 (GLOBE NEWSWIRE) -- Bone Biologics Corporation ("Bone Biologics" or the "Company") (NASDAQ: BBLG, BBLGW), a developer of orthobiologic products for spine fusion markets, today announces that the validated shelf life of its rhNELL-1 protein has been extended to 32 months.
“Reaching a 32-month validated shelf life gives us greater flexibility in how we manufacture, store and distribute rhNELL-1 as we prepare for pivotal-study scale,” said Jeff Frelick, Chief Executive Officer. “We have achieved each stability milestone on the timeline communicated to shareholders. By extending the period the product can be held before use, we believe this milestone supports more efficient lot sizing, inventory management and distribution planning as our first-in-human NB1 study advances toward completion of enrollment.”
The extension is supported by third-party stability data and builds on the 29-month milestone announced in May 2026 and the 24-month milestone achieved in December 2025, continuing a progression from the Company's earlier validated 12- and 18-month shelf-life milestones. A 32-month validated shelf life is expected to further enhance manufacturing efficiency, lot sizing, inventory management, distribution planning, and supply-chain flexibility as the Company advances rhNELL-1 through development.
NB1, the Company’s lead product candidate, combines rhNELL-1 protein with demineralized bone matrix to provide controlled bone regeneration. Bone Biologics is currently conducting a multicenter, prospective, randomized pilot clinical study evaluating NB1 in up to 30 subjects with degenerative disc disease undergoing transforaminal lumbar interbody fusion in Australia.
