Clinical trial summary

In this clinical trial we are recruiting healthy male and female participants aged 18 to 40. This clinical trial aims to evaluate how safe and tolerable different doses of the study medication will be in your body. It also evaluates how the body absorbs, breaks down and excretes the study medication (pharmacokinetics) as well as the effect of the study medication on vitamin A and certain protein (Transthyretin) levels in the blood (pharmacodynamics). If the trials are successful and this study medicine is approved, it would be used to treat people with aTTR amyloidosis.

If you are interested in participating in the trial:-

  • You will need to attend a screening appointment so we can check if you are suitable to take part in the trial. At this appointment we will take blood samples, check your heart function, and carry out a physical examination.
  • If results from your screening appointment show you are suitable for the trial, you will be invited to take part.
  • This will involve a stay of six days / five nights in our clinical research unit.
  • After your stay with us, you will be required to return for further appointments on Day 8, Day 15, Day22, Day 29, Day 43, Day 57, Day 90, Day 180, Day 270, Day 315, and Day 360 of the trial.
  • In total, if you are included (receive the study medicine) in the clinical trial you will come to the research unit 13 times over a period of 20 months.
  • During your stay with us you will receive a single dose of the study medicine by injection under the skin and we will conduct a number of assessments (like those we did at screening) to check how well you tolerate the study medicine, and to help us understand how long it takes for your body to process the study medicine.
