NW Bio Reaches 30 Clinical Trial Sites Ahead of End-of-Q1 Projection Projections Met or Exceeded For Fourth Consecutive Quarter

BETHESDA, Md., Feb. 23, 2012 /PRNewswire/ -- Northwest Biotherapeutics (OTC.BB: NWBO) (NW Bio) today announced that it now has 30 clinical trial sites open and recruiting across the United States in its ongoing Phase 2 clinical trial of DCVax®-L immune therapy for Glioblastoma multiforme (GBM), the most lethal form of brain cancer.  The Company reached this milestone ahead of schedule, as the Company had projected to reach it by the end of Q1, 2012.  The Company likewise met or exceeded its projections in the three preceding quarters (Q2, Q3 and Q4 of 2011), as previously announced.

The Company plans to continue adding clinical trial sites, and expects to have at least 40 sites open and enrolling by the end of Q2, 2012.  The Company will also continue pursuing its programs in Europe.  The open and active trial sites are listed on the U.S. Government's website, www.clinicaltrials.gov, and on NW Bio's website, www.nwbio.com

As previously stated, the Company's progress continues to reflect the growing interest from both physicians and patients, and a growing awareness of the positive data from the Company's prior clinical trials for GBM brain cancer.  In those trials, patients who received DCVax® showed a median survival of 3 years compared with median survival of 14.6 months for patients who received standard of care (surgery, radiation and chemotherapy).  Patients who received DCVax® also experienced a substantially longer time to tumor recurrence: a median of 2 years, compared with 6.9 months in patients who received standard of care.  DCVax® was well-tolerated, with no toxic side effects.

Linda Powers, CEO of NW Bio, commented that "Together with our recently announced partnership with the American Red Cross, the ongoing expansion of our clinical trial sites is helping to build a broad network to bring DCVax® to patients throughout the country.  We are pleased to see the continuing expansion of interest in DCVax® in the medical community."
