Medida Descripción |
Periodo de tiempo |
|---|---|---|
|
Percentage of Participants Who Tolerated a Single Dose of >= 600 mg (1044 mg Cumulative Tolerated Dose) of Peanut Protein Without Dose-limiting Symptoms
Periodo de tiempo: Week 4
|
Responder rate was defined as the percentage of participants tolerating a single dose of >= 600 mg (1044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms during the double blind placebo controlled food challenge (DBPCFC).
The cumulative tolerated dose is the sum of the tolerated doses, not including the reactive dose.
Dose-limiting symptoms indicate a true allergic reaction occurring during administration of a single dose of peanut protein at the DBPCFC that should preclude the administration of any further doses in the view of the investigator.
Symptoms that require administration of any rescue medication were considered dose-limiting symptoms.

Change From Baseline of Peanut-specific IgE (Including Peanut Components)
Periodo de tiempo: Baseline, Day 25 pre-dose and Day 31 (End of Study)
|
IgE is a soluble biomarker that provide LOU064 response to treatment and disease severity biomarkers.
|
Baseline, Day 25 pre-dose and Day 31 (End of Study)
|
|
Change From Baseline of Peanut-specific IgG4 (Including Peanut Components)
Periodo de tiempo: Baseline, Day 25 pre-dose and Day 31 (End of Study)
|
IgG4 is a soluble biomarker that provide LOU064 response to treatment and disease severity biomarkers.
|

|
|
Change From Screening in Allergen-specific Skin Prick Test (SPT) Mean Wheal Diameters
Periodo de tiempo: Baseline, Day 26
|
An allergen specific skin prick test (SPT) is a commonly used diagnostic tool.
In this study a titration SPT using peanut allergen provided additional information on the impact of Bruton's tyrosine kinase (BTK) suppression on skin mast cells.
Skin reactions were recorded after 15 minutes of applying allergen to the pricked location.
The size of the wheel and flare (the longest diameter and the midpoint orthogonal diameter) at each site were recorded.

Baseline, Day 26
|
|
Maximum Observed Blood Concentration (Cmax) of LOU064
Periodo de tiempo: Day 8 and Day 25: pre-dose, 0.5, 1, 2, 3, 4 hours.
|
Cmax is the maximum (peak) observed blood concentration of LOU064 after dose administration.
Pharmacokinetic parameters were calculated using a non-compartmental method (WinNonLin Version 8.3.4 or higher).
The LOU064 concentration was determined by a validated Liquid chromatography-mass spectrometry (LC-MS/MS) method with a lower limit of quantification (LLOQ) of 0.1 ng/mL.
|
Day 8 and Day 25: pre-dose, 0.5, 1, 2, 3, 4 hours.
|
|
Area Under Blood Concentration-time Curve (AUClast) of LOU064
Periodo de tiempo: Day 8 and Day 25: pre-dose, 0.5, 1, 2, 3, 4 hours.
|
AUClast is the area under the blood concentration-time curve from time zero to the time of last quantifiable concentration (tlast) of LOU064.
Pharmacokinetic parameters were calculated using a non-compartmental method (WinNonLin Version 8.3.4 or higher).
The LOU064 concentration was determined by a validated Liquid chromatography-mass spectrometry (LC-MS/MS) method with a lower limit of quantification (LLOQ) of 0.1 ng/mL.
|
Day 8 and Day 25: pre-dose, 0.5, 1, 2, 3, 4 hours.
|
|
Area Under Plasma Concentration-time Curve (AUCtau) of LOU064
Periodo de tiempo: Day 8 and Day 25: pre-dose, 0.5, 1, 2, 3, 4 hours.
|
AUCtau is the area under the plasma concentration-time curve.
Estimation of AUCtau values required extrapolation of the concentration-time profile from the last measured time-point at 4 h to the end of dosing interval at 12 h post-dose.
In some cases, this extrapolation was not possible.
For this reason, the number of participants with measurable AUCtau values was less when compared to those with AUClast.
Pharmacokinetic parameters were calculated using a non-compartmental method (WinNonLin Version 8.3.4 or higher).
The LOU064 concentration was determined by a validated Liquid chromatography-mass spectrometry (LC-MS/MS) method with a lower limit of quantification (LLOQ) of 0.1 ng/mL.
|
Day 8 and Day 25: pre-dose, 0.5, 1, 2, 3, 4 hours.
|
|
Time to Reach Maximum Observed Blood Concentration (Tmax) of LOU064
Periodo de tiempo: Day 8 and Day 25: pre-dose, 0.5, 1, 2, 3, 4 hours.
|
Tmax is the time to reach maximum (peak) of LOU064 blood concentration after single-dose administration (time).
Pharmacokinetic parameters were calculated using a non-compartmental method (WinNonLin Version 8.3.4 or higher).
The LOU064 concentration was determined by a validated Liquid chromatography-mass spectrometry (LC-MS/MS) method with a lower limit of quantification (LLOQ) of 0.1 ng/mL.
|
Day 8 and Day 25: pre-dose, 0.5, 1, 2, 3, 4 hours.
|
|
Number of Participants Presenting Maximum Severity of Symptoms Occurring at Any Challenge Dose of Peanut Protein up to and Including 1000mg During the DBPCFC
Periodo de tiempo: 4 weeks
|
Responder rate was defined as the percentage of participants tolerating a single dose of >= 3000 mg (5044 mg cumulative tolerated dose) of peanut protein without dose-limiting symptoms during the double blind placebo controlled food challenge (DBPCFC).
The cumulative tolerated dose is the sum of the tolerated doses, not including the reactive dose.
Dose-limiting symptoms indicate a true allergic reaction occurring during administration of a single dose of peanut protein at the DBPCFC that should preclude the administration of any further doses in the view of the investigator.
Symptoms that require administration of any rescue medication were considered dose-limiting symptoms.
