Study summary

The objective of this study is to evaluate the effect of LJPC-501 infusion on mean arterial pressure (MAP) or reduction in sum norepinephrine (NE) equivalent dosing, at Hour 2 after the start of LJPC-501, in pediatric patients who remain hypotensive despite receiving fluid therapy and vasopressor therapy. In addition, this study will evaluate the safety and tolerability of LJPC-501 in pediatric patients, the change in MAP over 24 hours after the start of LJPC-501, the change in serum lactate concentrations, and the change in Pediatric Logistic Organ Dysfunction (PELOD) scores.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Study arms

  • Experimental
    LJPC-501

    Angiotensin II administered via continuous infusion (1.25 - 40 ng/kg/min) for 24 hours up to 168 hours.

    Drug: Angiotensin II

Interventions

  • Angiotensin II is a peptide hormone naturally produced by the body that regulates blood pressure via vasoconstriction and sodium reabsorption. LJPC-501 (angiotensin II) is being developed for the treatment of hypotension in patients who do not respond to fluids and vasopressor therapy.

    Also known as: Giapreza

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2018 to primary completion in Apr 2018, 2 months.

Of 60 phase 2 interventional studies under Sepsis, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 37. This study's 2 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 7, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
