What is SENS-111?

First-in-class, histamine H4 receptor antagonist selected to treat acute unilateral vestibulopathy:

  • Administered orally
  • No sedative effect

Works by having a pronounced inhibitory effect on vestibular neuron activity, thus, reducing vestibular tone imbalance.

Should alleviate vertigo symptoms without the common sedative effects of current off-label vertigo treatments.

Preclinical and Clinical Data

Data from several preclinical and clinical studies are available, with a phase 2 study ongoing.

  • Pharmacokinetics, pharmacodynamics, safety and tolerance evaluated in several preclinical studies and multiple phase 1 trials
  • Good inner ear exposure after systemic administration in preclinical studies

A multicenter, randomized, double-blind, placebo-controlled phase 2 study is initiated to assess the efficacy and safety of 2 oral doses (100 mg and 200 mg) for 4 days in patients with acute unilateral vestibulopathy. [Clinicaltrials.gov 2017].

 


About Acute Unilateral Vestibulopathy (AUV)

AUV (also called vestibular neuritis) is a cause of severe acute vertigo.

AUV is a rare or orphan disease (annual incidence of 3.5 to 15.5 per 100,000 persons), with the usual age of onset between 30 and 60 years.

Although no commonly accepted cause has been established, potential causes include viral, vascular, autoimmune or infectious origins.

Key symptoms are:

  • Acute onset of sustained rotatory vertigo   
  • Apparent movement of visual surroundings (external vertigo) and pathologic deviation of the subjective visual vertical  
  • Postural imbalance with a tendency to fall toward the affected side   
  • Nausea and vomiting
  • Horizontal, torsional nystagmus beating towards the non-affected side

These so-called "big-five" symptoms allow a differentation between peripheral or central vestibular lesions.   

 

SENS-111 is protected by several patent families until at least 2028.
