Bone Biologics Improves Extension of rhNELL-1 Product Shelf Life to 24 Months

Milestone advances manufacturing readiness and supports long-term commercialization strategy

BURLINGTON, Mass., Dec. 23, 2025 (GLOBE NEWSWIRE) — Bone Biologics Corporation (“Bone Biologics” or the “Company”) (NASDAQ: BBLG, BBLGW), a developer of orthobiologic products for spine fusion markets, announces it has received confirmation that the shelf life of its rhNELL-1 product has been extended to 24 months, delivering on previously communicated forecasts.

The extended shelf life is validated by ongoing stability data and represents a logical progression from prior validated 12- and 18-month shelf-life milestones. Achieving a 24-month shelf life is expected to enhance manufacturing efficiency, inventory management, supply-chain flexibility, and clinical and commercial readiness as the Company advances rhNELL-1 through development.

“This milestone reflects continued execution against our development and manufacturing objectives,” stated Jeff Frelick, Bone Biologics Chief Executive Officer. “We believe extending the expected shelf life of rhNELL-1 to 24 months, as previously forecasted, is an important step toward commercialization, improving manufacturing efficiency, supply-chain flexibility, and product readiness. As we advance rhNELL-1 through clinical development, these operational milestones are expected to support disciplined capital deployment and long-term shareholder value creation.”

Bone Biologics continues to develop rhNELL-1 as a differentiated bone growth factor designed to promote controlled, targeted bone regeneration, particularly in hard-to-heal fusion settings.
