Tengion Provides Corporate and Product Development Update and Reports Second Quarter 2010 Financial Results

- Enhances Enrollment Effort in Tengion Neo-Urinary Conduit™ Trial

EAST NORRITON, Pa., Aug. 11, 2010 /PRNewswire-FirstCall/ -- Tengion Inc. (Nasdaq: TNGN) today provided a corporate and product development update and reported its financial results for the quarter ended June 30, 2010.

Neo-Urinary Conduit Clinical Update

The Neo-Urinary Conduit is an implant designed to catalyze regeneration of native-like urinary tissue in patients with bladder cancer who require a urinary diversion following bladder removal, or cystectomy.   A Phase I clinical trial underway at the University of Chicago is designed to establish the safety profile for the product as well as confirm the surgical technique to be utilized.  Over the past few months, the site has screened dozens of patients requiring bladder removal, but has not yet enrolled the first patient in the trial.  Enrollment has been slower than initially anticipated due to selective enrollment criteria that are typical for an initial clinical trial with a new product candidate using a novel technology and limited patient understanding of the benefits and risks of current surgical options relative to those of the Neo-Urinary Conduit.  

Tengion has undertaken a number of initiatives to address these challenges and to enhance enrollment.  To increase the number of patients screened, the University of Chicago is conducting outreach to referring hospitals and Tengion is working to initiate an additional study site.  Educational materials have been developed and are now in use to guide discussion with patients about current surgical options and the alternative of the Neo-Urinary Conduit.  Based on these activities, the first patient enrollment is anticipated in the near term, which may permit disclosure of interim data on the first patient by the end of the year.

"During the second quarter, we identified potential causes of delayed enrollment for the first patient in our Neo-Urinary Conduit study," stated Steven Nichtberger, M.D., President and Chief Executive Officer of Tengion.  "Under the direction of our newly hired Chief Medical Officer, we have taken actions that should enhance the investigator's ability to enroll the first patient in our study."

Neo-Kidney Augment Program Update

The Neo-Kidney Augment is Tengion's lead discovery program and is designed to prevent or delay the need for dialysis or kidney transplant by increasing functional renal mass in patients with advanced chronic renal disease, a significant unmet medical need.

• In May, 2010, Tengion scientists presented new research data in podium presentations at the 16th Annual Meeting of the International Society for Cellular Therapy (ISCT).  These data demonstrated that bio-active renal cells, like those used in Tengion's Neo-Kidney Augment program, can reduce the rate of loss of functional kidney mass in an aggressive preclinical model of chronic kidney disease.  Data were also presented at ISCT confirming that the necessary regenerative cells being used in Tengion's preclinical models can be isolated, characterized and expanded from diseased human kidneys.  These results have been submitted for peer-reviewed scientific publication.

• Tengion plans to present new data from an ongoing study of the Neo-Kidney Augment in a diabetic, obese, hypertensive animal model of renal failure at a meeting of the ISCT, on September 28, 2010 in San Francisco, CA.

• Tengion continues to expect to announce the initial results from a study of large animals evaluating the Neo-Kidney Augment in the fourth quarter of 2010.

"We are making significant progress in our renal program.  In an aggressive animal model of renal failure, the Neo-Kidney Augment product candidate demonstrated the ability to stabilize and preserve renal function.  We look forward to presenting additional data at scientific sessions later this year," said Dr. Nichtberger.

Financial Update

For the second quarter ended June 30, 2010, the Company reported an adjusted net loss of $6.5 million or $0.58 per basic and diluted common share, compared with an adjusted net loss of $8.2 million, or $1.28 per basic and diluted common share, for the same period in 2009.  The loss per basic and diluted common share for the quarter ended June 30, 2010 was significantly affected by the Company's initial public offering of 6,000,000 shares in April 2010.

Total operating expenses for the second quarter ended June 30, 2010 were $5.9 million compared with $7.3 million for the same period of 2009.  The 19% decrease in operating expenses was driven primarily by a decrease in research and development expense for the Company's preclinical and clinical studies.

As of June 30, 2010, the Company held $27.4 million in cash, cash equivalents and short-term investment compared with $9.1 million on March 31, 2010.

About Tengion

Tengion, a clinical-stage biotechnology company, has pioneered the Organ Regeneration Platform that enables us to create proprietary product candidates that are intended to harness the intrinsic regenerative pathways of the body to produce a range of native-like organs and tissues. Tengion's product candidates seek to eliminate the need to utilize other tissues of the body for a purpose to which they are poorly suited, procure donor organs or administer anti-rejection medications. Tengion commenced a Phase I clinical trial in the first half of 2010 for its lead product candidate, the Neo-Urinary Conduit™, an autologous implant that is intended to catalyze regeneration of native-like bladder tissue for bladder cancer patients requiring a urinary diversion following bladder removal. Tengion has also applied its technology in two Phase II clinical trials for Tengion's Neo-Bladder Augment™ for the treatment of neurogenic bladder and is in preclinical development of its Neo-Kidney Augment™. Tengion has worldwide rights to its product candidates.
