Study summary

The primary objective of this study is to evaluate pharmacokinetics (PK) of ravulizumab administered subcutaneously via an on-body delivery system (OBDS) compared with intravenously administered ravulizumab in adult participants with PNH who are clinically stable on eculizumab for at least 3 months prior to study entry.

Read the detailed description

The study will consist of up to a 30-day Screening Period, a 10-week Randomized Treatment Period, and an Extension Period of up to 172 weeks.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Male or female ≥18 years of age
  • Treated with eculizumab for PNH for at least 3 months prior to Day 1
  • LDH level ≤1.5 × (ULN) at screening
  • PNH diagnosis confirmed by documented high-sensitivity flow cytometry.
  • Documented meningococcal vaccination not more than 3 years prior to, or at the time of, initiating study treatment.
  • Body weight ≥40 to \<100 kilogram (kg)
  • Female participants of must use highly effective starting at screening and continuing until at least 8 months after the last dose of ravulizumab.
  • Willing and able to give written and comply with study visit schedule.

Exclusion criteria

Exclusion Criteria:

  • More than 1 LDH value > 2 × within the 3 months prior to study entry
  • History of bone marrow transplantation.
  • History of or ongoing major cardiac, pulmonary, renal, endocrine, or hepatic disease that, in the opinion of the Investigator or Sponsor, would preclude participation.
  • Unstable medical conditions (for example, myocardial ischemia, active gastrointestinal bleed, severe congestive heart failure, anticipated need for major surgery within 6 months of randomization, coexisting chronic anemia unrelated to PNH).
  • Females who are pregnant, breastfeeding or who have a positive pregnancy test at screening or Day 1.
  • Participation in another interventional clinical study or use of any experimental therapy within 30 days before initiation of study drug on Day 1 in this study or within 5 half-lives of that product, whichever is greater.
Terms in these criteria, in plain language(5)

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.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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.

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.

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 2019 to primary completion in Feb 2021, 23 months.

Results were first posted in Oct 2022, 1 year 8 months after primary completion. A results delay was requested in Jan 2021.

Of 35 industry-sponsored phase 3 interventional studies under Hemoglobinuria, Paroxysmal, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 41. This study's 23 months is close to that.

Counting every sponsor, half of 35 studies reached it within 23 months; a quarter within 15 and three quarters within 41.

How these figures are worked out, and which studies are left out of them.

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 Sep 19, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
