Study summary

A Multi-Centre, Phase II, Randomized, Double-Blind, Placebo-Controlled Study to investigate Efficacy and Safety of Sevuparin Infusion for the Management of Acute Vaso-Occlusive Crisis (VOC) in Subjects with Sickle-Cell Disease (SCD).

Read the detailed description

This will be a phase II, multi-centre, randomized, double-blind, placebo-controlled study designed to assess preliminary efficacy, safety and pharmacokinetics (PK) of 2-7 days continuous IV administration of sevuparin for the management of acute VOC in subjects with SCD.

Adults and adolescents ≥ 12 years of age will be randomized to treatment with sevuparin or placebo (ratio 1:1).

Terms in these criteria, in plain language(14)

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.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

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.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

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.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

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.

What researchers measure

Primary outcomes

  1. Time to resolution of VOC

    Time from start of infusion until resolution of VOC crisis/episode

    Time frame: From hospitalisation until discharge, defined as freedom from parenteral opioid use and readiness for discharge i.e. from randomisation until day 7

Secondary outcomes

  1. Frequency and pattern of treatment-emergent adverse event (TEAEs)

    All events to be reported from randomization until end of study

    Time frame: Time from start randomsiation until end of study, approximately 1 month 1 week after randomisation

  2. Pharmacokinetic (PK) characteristics of sevuparin

    PK characteristics of sevuparin during and after administration of sevuparin as a continuous IV infusion (subgroup) ◦Area under the plasma concentration versus time curve (AUC) of Sevuparin.

    Time frame: Pre dose, 1h, 2h, 24h, 1/day (day 3-8)

  3. Mean change in pain intensity

    VAS (visual analog scale) every fourth hour. Range from 0 (no pain) to 100 (max pain)

    Time frame: From baseline (visit 1) until day 3-7

  4. Duration of severest pain,

    Defined as time to a 30% reduction in pain intensity (VAS)

    Time frame: From baseline (visit 1) until day 3-7

  5. Cumulative dose of parenteral opioids

    Total dose of parenteral opioids

    Time frame: From baseline (visit 1) until day 3-7

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 Jul 2015 to primary completion in May 2019, 46 months.

Of 34 industry-sponsored phase 2 interventional studies under Anemia, Sickle Cell, half reached primary completion within 28 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 41. This study's 46 months is above that.

Counting every sponsor, half of 92 studies reached it within 46 months; a quarter within 24 and three quarters within 73.

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 Jul 16, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
