Summary

This trial aims to see if giving multiple doses of INZ-701 once a week for 4 weeks is safe and can increase pyrophosphate levels in individuals with kidney disease. It will also look

Who is the study for?
This trial is for adults with end-stage kidney disease who are on hemodialysis. It's specifically aimed at those with low pyrophosphate levels, a condition that can lead to calciphylaxis—a rare but serious skin condition.
What is being tested?
The study tests INZ-701, given weekly over a month, to see if it's safe and can raise pyrophosphate levels in patients. The trial also looks at how hemodialysis affects the drug and pyrophosphate in the body.
What are the potential side effects?
Since this summary doesn't provide specific side effects of INZ-701, generally speaking, potential side effects could include reactions at the injection site, changes in blood pressure or heart rate during dialysis sessions.

Trial Design

1Treatment groups
Experimental Treatment
Group I: INZ-701Experimental Treatment1 Intervention
The study consists of a 26-day treatment period where the dose of INZ-701 will be 1.8 mg/kg once weekly. INZ-701 will be administered as a subcutaneous injection once weekly for 4 weeks on Days 3, 10, 17, and 24. The study participant's post-hemodialysis body weight on Day 1 will be used to calculate the dose to be administered.
