Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Inclacumab is a recombinant human monoclonal antibody (huMAb) being developed for the treatment of sickle cell disease (SCD).

15 eligible participants will be enrolled in 2 dose cohorts and receive a single intravenous dose of 20 mg/kg or 40 mg/kg of inclacumab over a period of 1 hour. Doses will be administered by the study nurse.

Outcomes
Primary outcome [1] 324746 0
To assess the safety and tolerability of inclacumab after a single dose at different dose levels in healthy participants. Safety and tolerability will be assessed through review of ongoing safety assessments including clinical laboratory testing, physical examination, ECG and vitals as well as recording of any side effects..
Timepoint [1] 324746 0
Safety and tolerability will be assessed during the inpatient period following dosing (daily assessments for up to 4 days post-dose) and during the outpatient follow-up period, up to Day 203 (14 outpatient visits, 1-3 weeks apart)
Secondary outcome [1] 385627 0
To characterize the plasma pharmacokinetics (PK) of inclacumab in healthy participants including but not limited to, Cmax, AUC, and T1/2
Timepoint [1] 385627 0
Blood samples for PK will be collected at the following timepoint:
Day 1: pre-dose, end of infusion and 2, 6, & 12 hrs post end of infusion
Day 2, 3, 4, 8, 15, 22, 29, 43, 57, 71, 85, 99, 120, 141, 162, 183, 203
Secondary outcome [2] 387475 0

Timepoint [2] 387475 0
Blood samples for PD will be collected at the following timepoint:
Day 1: pre-dose, end of infusion and 2, 6, & 12 hrs post end of infusion

Summary
Brief summary
The purpose of this study is to assess the safety and tolerability of inclacumab, as well as the pharmacokinetics (PK – how your body uses the study drug) and pharmacodynamics (PD – how the study drug carries out its actions on the body).
