INOZYME PHARMA, INC.
INOZYME PHARMA, INC. is a registered legal entity registered in United States under 1284386, and its current status with Connecticut Secretary of the State — business.ct.gov is active. The company was incorporated on 10 September 2018 and lists its registered address as BOSTON, United States. 5 shareholders are on record for INOZYME PHARMA, INC., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Connecticut Secretary of the State — business.ct.gov and was last updated on 4 October 2026.

Shareholders
5
Five shareholders are currently on record for INOZYME PHARMA, INC., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Adage Capital Partners GP L.L.C., holding 12.9% — the largest recorded stake — followed by Pivotal bioVenture Partners Investment Advisor, LLC at 11.3%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Group Structure
INOZYME PHARMA, INC. sits 1 level below its ultimate parent, Biomarin Pharmaceutical Inc., registered in United States. 2 subsidiaries are recorded beneath it, across 3 jurisdictions. The full chain up to Biomarin Pharmaceutical Inc. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by INOZYME PHARMA, INC.'s own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 2 subsidiaries span United States, Switzerland, Ireland jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
