Trial overview
The available study of HEMOPEXIN, HUMAN was an interventional trial, which means researchers gave a study treatment and watched the results.[1] The trial studied people with sickle cell disease vaso-occlusive crisis, a painful episode caused by blocked blood flow.[1]
The study title says it evaluated safety, efficacy, and pharmacokinetics of CSL889 in adults and adolescents with sickle cell disease during vaso-occlusive crisis.[1] In the trial data, CSL889 is identified as HEMOPEXIN, HUMAN.[1]
Who participated
The trial included adults and adolescents with sickle cell disease who were having a vaso-occlusive crisis.[1] This means the study focused on patients during an active painful event, not on people without symptoms.[1]
The enrollment was 260 participants, so this was a fairly large study for this condition.[1]
What was studied
The main goal was to evaluate the safety and tolerability of HEMOPEXIN, HUMAN given by intravenous infusion.[1] Safety means whether unwanted medical problems happen, and tolerability means how manageable the treatment is for patients.[1]
The study also looked at whether HEMOPEXIN, HUMAN could help reduce the time needed for vaso-occlusive crisis to resolve.[1] In simple terms, the researchers wanted to know if the painful episode could end sooner.[1]
The intervention list shows that participants received either HEMOPEXIN, HUMAN or a placebo solution for infusion.[1] A placebo is a look-alike infusion with no active substance, used for comparison.[1]
Main endpoints
The primary outcome included time to resolution of vaso-occlusive crisis, measured as the time until parenteral opioids could be stopped.[1] This is a practical way to track when severe pain is improving enough that strong injected or infused pain medicine is no longer needed.[1]
The trial also measured treatment-emergent adverse events, which are medical problems that start or get worse after treatment begins.[1] Both the number of participants with these events and the percentage of participants affected were recorded.[1]
Another endpoint was the number and percentage of participants with detectable treatment-emergent anti-CSL889 antibodies.[1] Antibodies are proteins made by the immune system, and this measure checks whether the body reacted to the study treatment.[1]
Trial phase and status
This study was a Phase 4 trial.[1] Phase 4 studies are later-stage trials that examine a treatment in a broader patient setting.[1]
The trial status was Completed.[1] That means the planned study activities were finished.[1]
What the study means for patients
For patients with sickle cell disease, this trial was designed to see whether HEMOPEXIN, HUMAN could help during a painful vaso-occlusive crisis while also being monitored for safety.[1] The study focused on a real hospital-style situation where patients often need strong pain treatment.[1]
Because the trial compared HEMOPEXIN, HUMAN with placebo, the results were meant to show whether any changes seen were likely due to the study treatment rather than chance alone.[1] The main patient-centered outcome was how quickly the crisis ended and pain medicine could be stopped.[1]
