Describes DCVax® Science and Company’s Progress

BETHESDA, MD, November 1, 2011 — Northwest Biotherapeutics (OTC.BB: NWBO) (Northwest Bio) today announced, as part of its program of public outreach and education, the availability online of an interview of Northwest Bio Chairman and CEO Linda Powers by CEO/CFO Publication.

The interview describes in layman’s terms both the encouraging science behind DCVax® and the progress now being made in both the US and Europe towards being able to make this promising technology available to cancer patients.

By way of historical background, Ms. Powers observes that, “What attracted me to Northwest Biotherapeutics was that they have a platform technology that should be applicable to pretty much all cancers, and which is offering really a major improvement in survival times for patients, with no toxicity. The drugs that are out there today typically only add ten weeks of survival and they have a heck of a toxicity profile. Therefore, the combination of the effectiveness, the lack of toxicity, and the fact that it may be applicable to any cancer really was very exciting.”

In describing the technology, Ms. Powers noted, “The key to the Northwest technology was figuring out, number one, which type of immune cell is the master immune cell. In other words, who the General of the Army is, because if you are going to give the key signals, the marching orders, you have to give them to the right party who can implement them. Therefore, one key thing was figuring out that the dendritic cells are the master cells of the immune system. The immune system has so many players.”

The full interview is available on the Company’s website, www.nwbio.com as well as on. http://ceocfointerviews.com , CEO/CFO Publication’s website.
