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

Placebo for IV infusion
The Drug Product sevuparin solution for IV infusion
- 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
- 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
- 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.
- 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)
- 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)
- Cumulative dose of parenteral opioids [ Time Frame: From baseline (visit 1) until day 3-7 ]Total dose of parenteral opioids
