Heat test study for cholinergic urticaria subtypes
Part of Immune system & allergy, Skin clinical trials.
This trial uses a heat test to identify different groups of people with cholinergic urticaria (hives triggered by heat or exercise). It aims to better understand the condition and help tailor future treatments.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- You have been diagnosed with cholinergic urticaria (hives that appear when you get warm or exercise).
- You have had an exercise test (like walking on a treadmill) within the last 6 months.
- You are not currently taking antihistamines (must stop 72 hours before the heat test).
- You have not had severe reactions like trouble breathing, swelling, or anaphylaxis from hives.
- You are not pregnant or breastfeeding.

This study aims to better understand inducible urticaria (hives triggered by cold, pressure, or friction) and chronic spontaneous urticaria. Researchers will use skin tests to measure how different triggers affect your skin in detail.
This trial tests a new medicine called BBT001 for people with chronic spontaneous urticaria (long-lasting hives without a known cause). It aims to see if the drug is safe and helps reduce itching and hives.
This trial tests a new drug, GTX-B001, in healthy people and those with a type of hives called chronic inducible urticaria (specifically cold-induced or scratch-induced hives). The goal is to see if it's safe and helps control symptoms that don't respond well to standard antihistamines.
This trial tests a new medication (HS-10561) first in healthy adults to check safety, then in people with chronic spontaneous urticaria (long-term hives without a known cause) to see if it helps reduce symptoms. It may be an option for those who have had hives for at least 6 months.
This trial tests a new medication called THB335 for people with chronic spontaneous urticaria (CSU), which causes hives and itching for months without a clear cause. The study will see if the drug can reduce hives and itching better than a placebo (a pill with no active medicine).
This trial tests an experimental medicine for chronic hives (called chronic spontaneous urticaria). It is for people whose hives still bother them about once or twice a month despite daily treatment, and who do not have heart problems.
