Upstream Bio Launches with $200M Series A Financing to Advance Novel Therapeutics for Allergic and Inflammatory Diseases

  • Clinical-stage program UPB-101 targets the TSLP receptor, a cytokine receptor positioned upstream in the inflammatory cascade with the potential to impact multiple diseases, including asthma
  • Pipeline growth strategy includes pursuing UPB-101 in multiple diseases and acquiring additional drug candidates
  • Aaron Deykin, MD, appointed as Chief Medical Officer and Head of Research and Development

WALTHAM, Mass.--(BUSINESS WIRE)-- Upstream Bio, a biotech company focused on inflammation, today debuted with a $200 million Series A financing. The funding will allow Upstream to advance the company’s lead program UPB-101, a clinical-stage monoclonal antibody targeting the TSLP receptor, and build a pipeline of assets to address immune-mediated diseases. The Series A round was led jointly by OrbiMed and Maruho Co., Ltd. with participation from Access Biotechnology, Decheng Capital, HBM Healthcare Investments, TCG X, Omega Funds, Samsara BioCapital, and Altshuler Shaham Provident Funds Ltd.

Upstream Bio acquired UPB-101 from Astellas following the successful completion of initial clinical and preclinical studies. Upstream has selected asthma as the first indication for UPB-101 with plans to pursue additional diseases driven by TSLP-mediated inflammation. Inhibiting TSLP signaling is a validated mechanism. Stimulated by allergens, viruses, and other triggers, release of TSLP is at the top of the inflammatory cascade and a key driver of inflammatory response in major allergic and inflammatory diseases, including asthma. TSLP signaling occurs upstream of other validated targets such as IL-4, IL-5, IL-13, IL-17 and IgE.

“Because TSLP signaling occurs upstream of other targets, we have an opportunity to impact a fundamental aspect of asthma pathobiology,” said Aaron Deykin, MD, Chief Medical Officer and Head of Research and Development. “Targeting the TSLP receptor is a compelling mechanism, providing the potential to inhibit multiple pathological processes with a single treatment. We plan to establish clinical proof-of-concept in asthma, where we believe UPB-101 can deliver meaningful efficacy across a broad spectrum of severe asthma patients regardless of inflammatory phenotype.”

“Beyond asthma, we plan to pursue additional inflammatory diseases with UPB-101 and explore new additions to our pipeline where we believe we can deliver meaningful outcomes for patients,” said Samantha Truex, Chief Executive Officer of Upstream Bio. “Upstream is thrilled that Dr. Aaron Deykin has joined the team to lead translational and development efforts. We will benefit from his deep experience in both drug development and clinical care for patients with asthma and other inflammatory diseases.”

“Upstream Bio is led by a passionate and experienced leadership team with the drive to make a broad impact across allergic and inflammatory diseases,” said Ron Renaud, Chair of the Board for Upstream Bio. “The company is well-funded with a strong investor syndicate. Upstream is positioned to make a tremendous impact for patients.”
