The company’s research programs were aimed at addressing conditions involving inflammation, itching and other skin-related symptoms. Its lead investigational product was SNA-120, also known as pegcantratinib, a neurotrophic tyrosine kinase receptor A (TrkA) inhibitor studied for the treatment of pruritus associated with conditions such as atopic dermatitis and psoriasis. Sienna also evaluated additional topical and dermatology-focused drug candidates during its development program. Based in California, Sienna conducted its clinical development activities primarily in the United States. The company later discontinued its development programs and entered bankruptcy proceedings, and Sienna Biopharmaceuticals is no longer an operating biotechnology company. Its historical public-market security traded under the symbol SNNAQ.AI Generated. May Contain Errors.
