Yes. 4 of its 5 ClinicalTrials.gov trials are recruiting. Eligibility and site contacts are on each trial's record. Only the study team can confirm whether a patient is eligible.
Every trial, status, phase and condition on this page is copied from public ClinicalTrials.gov and EU CTIS records by a daily sync, grouped by the sponsor name each registry records. It says nothing about the organisation beyond its registered trials, and it is not medical advice.
Everything on this page is copied from public registry records — it is not written from memory, and nothing here describes the organisation beyond its registered trials. Each trial links to its own record so you can check it yourself.
This page is built automatically: a daily sync job reads the registry records behind our trial registers and groups every current trial by its lead sponsor name, ignoring legal-form suffixes such as Inc. or Ltd. A small, hand-checked list joins the same organisation's different registry names (for example its EU legal entity). There is no AI drafting and no per-sponsor editorial pass. The “last verified” date above is the timestamp of that sync, not a review date. Our general editorial approach is described in our editorial standards and corrections policy.
