A Study of CDX-0159 in Patients With Chronic Inducible Urticaria

Phase 2
Active, not recruiting
Conditions
Chronic Inducible Urticaria
Interventions
Biological: barzolvolimab
Drug: Matching Placebo
Registration Number
NCT05405660
Lead Sponsor
Celldex Therapeutics
Brief Summary

The purpose of this study is to assess the clinical effect, the pharmacodynamics, the safety, and the pharmacokinetics of barzolvolimab (CDX-0159) in patients with Chronic Inducible Urticaria who remain symptomatic despite the use of H1-antihistamines.

Detailed Description

The purpose of this study is to assess the clinical effect, the pharmacodynamics, the safety, and the pharmacokinetics of barzolvolimab in patients with Chronic Inducible Urticaria (Cold Urticaria \[ColdU\] or Symptomatic Dermographism \[SD\]) who remain symptomatic despite the use of H1-antihistamines.

There is a screening period of up to 4 weeks, followed by a 20-week treatment period where patients will receive either barzolvolimab 150mg, 300mg or placebo, and then a 24-week follow up period where all patients are observed.

Primary Outcome Measures
NameTimeMethod
Percentage of patients with a negative provocation test at week 12From baseline to week 12

Percentage of patients with a negative provocation test for Cold Inducible Urticaria \[ColdU\] or Symptomatic Dermographism \[SD\]) at week 12

* For ColdU patients, a negative provocation test is defined as absence of wheals at the provocation site within 10 min at ≤ 4°C after provocation using TempTest®

* For SD patients, a negative provocation test is defined as absence of wheals at the provocation site within 10 min at 0 pins after provocation using the FricTest®

Secondary Outcome Measures
NameTimeMethod
Change in worst itch reported after provocation in both SD and ColdUFrom baseline to week 12

Mean change in worst itch reported by numerical rating scale after provocation testing from baseline to week 12 in patients with SD and ColdU combined

Change in provocation threshold for SDFrom baseline to week 12

Mean change from baseline to Week 12 in Critical Friction Threshold (CFT) in patients with SD

CFT is the threshold pin number at which wheals are triggered, assessed at the 10-minute mark

Change in worst itch reported after provocation for ColdUFrom baseline to week 12

Mean change in worst itch reported by numerical rating scale after provocation testing from baseline to week 12 in patients with ColdU

Change in provocation threshold and itch for ColdUFrom baseline to week 12

Mean change from baseline to week 12 in critical temperature threshold (CTT) in patients with ColdU

CTT is defined as threshold temperature at which wheals are triggered (highest temperature for cold), assessed at the 10-minute mark

Combined patients with a negative provocation test at week 12From baseline to week 12

Percentage of combined patients with a negative TempTest (ColdU) or FricTest (SD) at week 12

Change in worst itch reported after provocation for SDFrom baseline to week 12

Mean change in worst itch reported by numerical rating scale after provocation testing from baseline to week 12 in patients with SD

Percentage of patients experiencing adverse eventsFrom baseline to week 20

Percentage of patients experiencing treatment-emergent adverse events (TEAE) examined by ColdU patients, SD patients and in combination. A TEAE is any untoward medical occurrence in a patient administered a study treatment.
