Phase 2 study of ENB-0040 for the treatment of hypophosphatasia (HPP)

Enobia Pharma announced that it has successfully completed a Phase 2 study of ENB-0040 (asfotase alfa) for the treatment of juveniles with hypophosphatasia (HPP).  HPP is a serious, rare metabolic bone disorder caused by a deficiency in the enzyme tissue non-specific alkaline phosphatase (TNSALP). This six-month, multinational, open-label investigation of the safety, tolerability, pharmacokinetics (PK), and efficacy of ENB-0040 treatment enrolled 13 children (5–12 years of age and Tanner Stage ≤2) with rickets and gross motor deficits from HPP. The juvenile study has met its primary endpoint, demonstrating a statistically significant improvement in rickets when compared with historical matched cohort controls (p=0.002). Nine of 13 children enrolled (69%) and nine of 12 children completing the study (75%) achieved a substantial improvement in rickets as assessed by skeletal radiographs of the wrists and knees, compared with two of 17 (12%) historical controls.

ENB-0040 is a subcutaneous enzyme replacement therapy of TNSALP fused to a bone targeting peptide. ENB-0040 is designed to directly target TNSALP to the bone in order to correct the enzyme deficiency, which could lead to restoration of normal bone mineralization.
