Brief 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).

Condition or disease Intervention/treatment Phase
Sickle-Cell Disease Drug: Sevuparin Other: Placebo Phase 2

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).

Arm Intervention/treatment
Placebo Comparator: Placebo
Placebo infusion
Other: Placebo
Placebo for IV infusion

Experimental: Sevuparin
Sevuparin infusion
Drug: Sevuparin
The Drug Product sevuparin solution for IV infusion

Primary Outcome Measures :
  1. Time to resolution of VOC [ Time Frame: From hospitalisation until discharge, defined as freedom from parenteral opioid use and readiness for discharge i.e. from randomisation until day 7 ]
    Time from start of infusion until resolution of VOC crisis/episode

Secondary Outcome Measures :
  1. Frequency and pattern of treatment-emergent adverse event (TEAEs) [ Time Frame: Time from start randomsiation until end of study, approximately 1 month 1 week after randomisation ]
    All events to be reported from randomization until end of study

  2. Pharmacokinetic (PK) characteristics of sevuparin [ Time Frame: Pre dose, 1h, 2h, 24h, 1/day (day 3-8) ]
    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.

  3. Mean change in pain intensity [ Time Frame: From baseline (visit 1) until day 3-7 ]
    VAS (visual analog scale) every fourth hour. Range from 0 (no pain) to 100 (max pain)

  4. Duration of severest pain, [ Time Frame: From baseline (visit 1) until day 3-7 ]
    Defined as time to a 30% reduction in pain intensity (VAS)

  5. Cumulative dose of parenteral opioids [ Time Frame: From baseline (visit 1) until day 3-7 ]
    Total dose of parenteral opioids
