Theradaptive Announces Final Patient Enrolled in RESTORE Feasibility Study Evaluating OsteoAdapt® DE in Dental Procedures

Study enrollment completion marks critical milestone in advancing bone regeneration for dental reconstruction using Theradaptive's targeted therapeutic platform

FREDERICK, Md., April 23, 2026 /PRNewswire/ -- Theradaptive, Inc., a clinical-stage biotechnology company pioneering targeted protein therapeutics for tissue regeneration, today announced the successful treatment of the 45^th and final patient in the RESTORE International Phase I/II Feasibility Study. This prospective, blinded, randomized, controlled study is designed to evaluate the safety and performance of OsteoAdapt^® DE, a next-generation regenerative product developed to promote bone growth in alveolar ridge augmentation, a surgical dental reconstruction procedure.

"Completing enrollment in the RESTORE study is a major achievement that validates the growing clinical interest in our platform," said Dr. Luis Alvarez, Founder and CEO of Theradaptive. "We are grateful to the investigators, clinical teams, patients, and partners whose dedication made this milestone possible. This achievement strengthens our growing body of clinical evidence and brings us closer to delivering meaningful new treatments for patients with limited options."

"Participating in the RESTORE study has provided valuable clinical insight into the potential of OsteoAdapt DE as an innovative approach to bone regeneration," said Dr. Ariel Hirschhorn, Principal Investigator at Sheba Medical Center, a participating site in the multicenter trial. "We are encouraged by its potential to address more complex craniomaxillofacial procedures and are proud to contribute to this important advancement in regenerative medicine."

OsteoAdapt^® DE and AMP2™ Technology

OsteoAdapt DE uses AMP2™, Theradaptive's engineered human bone morphogenetic protein-2 (BMP-2) variant. Unlike traditional graft materials that primarily rely on passive osteoconduction and can be slow to incorporate, OsteoAdapt DE is designed to promote active bone formation while minimizing residual material at the time of implant placement. This novel approach aims to accelerate healing and improve surgical outcomes. The RESTORE trial is evaluating the safety and performance of OsteoAdapt DE against standard xenograft bone grafts.

Support from AFIRM and Military Relevance

The study is supported by an Armed Forces Institute of Regenerative Medicine (AFIRM) Fiscal Year 2024 Clinical Trial Award, granted to Theradaptive through the Wake Forest Institute for Regenerative Medicine (WFIRM), and funded by the Defense Health Agency Research and Engineering Directorate, Department of Defense.

About Theradaptive's Clinical Pipeline

The RESTORE trial represents Theradaptive's second clinical trial and reflects the continued expansion of its clinical pipeline. Enrollment has also been completed in the OASIS Phase I/II Trial evaluating OsteoAdapt SP, a product under clinical investigation for spinal fusion. Together, these programs highlight the broad potential of the OsteoAdapt platform across multiple therapeutic areas.
