Clinical trials overview
The source data includes two interventional studies, which means researchers gave Ilofotase Alfa to study its effects in people.[1][2] Both trials are listed as completed.[1][2] One study was in people at risk for kidney damage after open heart surgery, and the other was in adults with hypophosphatasia.[1][2]
Trial in kidney damage after cardiac surgery
NCT06168799 studied Ilofotase Alfa for the prevention of renal damage after cardiac surgery, especially after open heart surgery.[1] The trial included 250 people and was a Phase 2 study.[1] Phase 2 studies usually look more closely at whether a treatment may help a specific problem in a larger group than early-stage trials.
The brief summary says the study aimed to assess the effect of Ilofotase Alfa on renal function, which means how well the kidneys work.[1] The study compared Ilofotase Alfa with a placebo, which is a look-alike product with no active study drug.[1]
Pilot trial in hypophosphatasia
The second study, 2023-503186-35-00, was a Phase 1 pilot trial in adults with hypophosphatasia.[2] It included 12 participants and tested a single dose of Ilofotase Alfa given by intravenous use, meaning through a vein.[2]
This early study looked at the effect of a low or high dose on the biochemical profile in adult HPP patients.[2] In simple terms, the researchers were checking how the treatment changed certain lab markers in the blood.[2]
What the trials measured
The cardiac surgery trial used the ratio between the highest serum creatinine value after surgery and the baseline value before surgery as its primary outcome.[1] Serum creatinine is a blood test that helps show kidney function.[1]
The hypophosphatasia trial measured changes in inorganic pyrophosphate (PPi) and pyridoxal 5’-phosphate (PLP) after low and high doses of Ilofotase Alfa.[2] These were used to see whether the treatment changed important lab values in adults with HPP.[2]
Study design and participation
Both studies were interventional, so the research team actively gave the study treatment rather than only observing people.[1][2] The cardiac surgery study used a placebo comparison, while the hypophosphatasia study focused on a single-dose pilot design.[1][2]
Based on the source data, participation was limited to people with the specific conditions being studied: risk for renal damage after open heart surgery in one trial, and adult hypophosphatasia in the other.[1][2] The data does not provide more detailed eligibility rules such as age cutoffs, lab limits, or other medical requirements.[1][2]
