What Was Sienna Biopharmaceuticals?
Sienna Biopharmaceuticals specialized in developing treatments for immunology and inflammation. Their unique value proposition lay in their innovative approach to topical photoparticle therapy.

What Happened to Sienna Biopharmaceuticals?
The story of Sienna Biopharmaceuticals is a classic example of a promising startup that faced insurmountable challenges, leading to its eventual downfall:
Initial Public Offering in 2017: Sienna Biopharmaceuticals went public in 2017, a significant milestone that showcased its potential in the biopharmaceutical industry. However, despite this achievement, the company struggled to maintain financial stability.
Financial Struggles and Bankruptcy: By September 2019, Sienna filed for Chapter 11 bankruptcy protection due to severe financial difficulties. The company borrowed hundreds of millions for research and development but failed to bring any products to market.
Failed Asset Sale: Efforts to sell the company or restructure were unsuccessful, with no bids received for the entire company. The sale of its topical photoparticle therapy assets to Sebacia for $1.7 million highlighted the undervaluation of its assets.
Negative Public Perception: The inability to secure a buyer or restructure effectively contributed to a negative public perception. This was compounded by the company's failure to gain approval for several of its drugs, further eroding investor confidence.
Closure and Layoffs: Ultimately, Sienna Biopharmaceuticals announced its shutdown and the layoff of its remaining employees by the end of the week in December 2019. This marked the end of a company that once held significant promise in the field of immunology and inflammation treatments.
When Did Sienna Biopharmaceuticals Shut Down?
Sienna Biopharmaceuticals shut down by the end of the week following December 12, 2019. This decision came after the company filed for Chapter 11 bankruptcy in September 2019 and failed to find a buyer for the entire company.
Why Did Sienna Biopharmaceuticals Shut Down?
Failed Drug Approvals: Sienna Biopharmaceuticals faced significant setbacks when several of its drugs did not gain regulatory approval. This failure hindered the company's ability to bring products to market, ultimately stalling revenue generation and contributing to its financial instability.
Inability to Secure Buyers: During its Chapter 11 bankruptcy proceedings, Sienna struggled to find a buyer for the entire company. Despite efforts to sell and restructure, no bids were received, which led to the decision to shut down operations and lay off remaining employees.
High R&D Costs: The company borrowed hundreds of millions of dollars for research and development but failed to launch any successful products. This high expenditure without corresponding revenue exacerbated its financial woes, making it difficult to sustain operations.
Asset Undervaluation: Sienna managed to sell its topical photoparticle therapy assets to Sebacia for $1.7 million, a figure that highlighted the undervaluation of its assets. This sale underscored the company's inability to capitalize on its innovations, further contributing to its downfall.
Negative Public Perception: The company's financial struggles and inability to secure drug approvals led to a negative public perception. This eroded investor confidence and made it challenging to attract new investments, sealing the company's fate.
