Tengion

Tengion, Inc. operated as a clinical-stage regenerative medicine company, focusing on the discovery, development, and manufacturing of neo-organs and neo-tissues. The company was founded in 2003 by Dr. Anthony Atala, director of the Wake Forest Institute for Regenerative Medicine, and Dr. Steven Nichtberger, who also served as its initial President and CEO. Tengion's core business was centered on its Organ Regeneration Platform, which utilized a patient's own (autologous) cells to grow new tissues and organs on a biodegradable scaffold. This approach was designed to regenerate native-like organs, with the ultimate goal of eliminating the need for donor transplants and the associated risks of rejection and immunosuppressive therapies.

The company's technology was based on research from the laboratories of Dr. Atala and was licensed from institutions including Children's Hospital Boston and the Massachusetts Institute of Technology. Tengion's business model revolved around advancing its product candidates through rigorous clinical trials to gain regulatory approval and commercialize them. Its primary clients were patients with organ failure, specifically in the urologic, renal, and vascular fields. Key product candidates included the Neo-Urinary Conduit, intended for bladder cancer patients requiring bladder removal, and the Neo-Kidney Augment, designed to regenerate functional kidney tissue to delay or prevent the need for dialysis in patients with chronic kidney disease. The company also conducted Phase II trials for its Neo-Bladder Augment to treat conditions like neurogenic bladder.

Throughout its existence, Tengion achieved several milestones, including raising significant venture capital, with a Series B round of $50 million in 2006 and a $40 million IPO in 2010. It received orphan-drug designation from the FDA for its Neo-Urinary Conduit in 2011, which would have provided seven years of marketing exclusivity upon approval. Despite these advancements and strategic investments, including a collaboration with Celgene, Tengion faced persistent financial challenges. After struggling to raise sufficient capital to continue operations, the company filed for Chapter 7 bankruptcy in December 2014. Its assets, including the core technology, were subsequently acquired in 2015 by RegenMedTX, a new entity led by former Tengion executives.
