Conditions

Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Post-provocation Urticaria Activity Score (UASprovo)

    The Urticaria Activity Score (UAS) rates a participants' number of wheals and their itch severity on a scale from 0 to 6, with 6 being the most severe. UAS is assessed after provocation of urticaria by moderate exercise to cause sweating.

    Baseline to Day 7

Secondary Outcomes (1)

  • Number of Treatment Emergent Adverse Events

    From start of each treatment period (day 1 for the 1st treatment period or day 15 or 22 for the 2nd treatment period) until 3 days after end of each treatment period (day 11 for the 1st treatment period or day 25 or 32 for the 2nd treatment period)

Study Arms (2)

Active - Placebo

EXPERIMENTAL

Patients will receive active treatment for 7 days, followed by a washout period of 7 days and then placebo for 7 days

Drug: LEO 152020Drug: LEO 152020 placebo

Placebo - Active

EXPERIMENTAL

Patients will receive placebo for 7 days, followed by a washout period of 7 days and then active treatment for 7 days

Drug: LEO 152020Drug: LEO 152020 placebo

Interventions

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject with a history of Cholinergic urticaria diagnosis for ≥ 6 months
  • Subject has active and uncontrolled Cholinergic urticaria disease at the time of screening and randomisation, as defined by the following:
  • Urticaria control test \< 12 at screening
  • Urticaria Activity Score post-provocation ≥ 3
  • Recent history (within 6 months of screening) with documented inadequate response to standard dose as to marketing authorization of H1 antihistamines.

You may not qualify if:

  • Other clearly dominating forms\* of urticaria as aetiology for wheal and flare type reactions
  • \*These diseases are allowed as comorbidities, if cholinergic urticaria is the dominating form of chronic urticaria,
  • Systemic immunosuppressive medications within 4 weeks prior to screening,
  • Systemic drugs (e.g. oral drug) with antihistamine properties including H1 antihistamines and some antidepressants (e.g. tricyclic antidepressants) and H2 antihistamines 1 week prior to randomisation and throughout the trial. However, topical antihistamines in the form of nasal spray and eyedrops are allowed in the standard prescribed dose.
