If this is close to home
This page includes language about advanced illness, prognosis, or palliative care, because that is how the trial's eligibility criteria are written. Seeing it set out plainly can land hard, whether it is about you or about someone you are caring for. You do not have to be at a crisis point to talk to someone.

Palliative care is not the same as giving up on treatment, and it is not only for the last weeks of life. It is symptom and comfort care that can run alongside active treatment, including a clinical trial.

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.
Not medical advice.
Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
