A Study of LJPC-501 in Patients with Catecholamine-Resistant Hypotension


About this study

The purpose of this study is to assess the effect of LJPC-501 (angiotensin II) on the mean arterial pressure in adult patients with catecholamine-resistant hypotension.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

  • ≥ 18 years of age
  • Catecholamine-resistant hypotension
