Inozyme Pharma is a global leader in developing therapies for rare mineralization disorders.

With our in-depth understanding of the biological pathways involved in mineralization, we are pursuing the development of therapeutics to address the underlying causes of these debilitating diseases. Two genes, ENPP1 and ABCC6, play key roles in a critical mineralization pathway and defects in these genes lead to abnormal mineralization.

We are initially focused on developing a novel therapy to treat the rare genetic diseases of ENPP1 and ABCC6 Deficiencies.

With a well-defined regulatory strategy, robust financial backing, and a strong business acumen, we are just getting started.

Experience counts. With decades of clinical, scientific, regulatory, commercial, and financial experience backing our work, we push boundaries to provide hope and transform patient lives.
