Al's Comment:

 This trial is for any type of cancer. Not sure yet if they include brain metastases. (They have another trial for GBM).

NW BIO HAS INITIATED ITS DCVAX®

-DIRECT PHASE I/II TRIAL 

FOR ALL SOLID TUMOR CANCERS 

MD Anderson Is The First Site; Other Sites In The US And UK To Follow 

BETHESDA, MD, June 13, 2013 -- Northwest Biotherapeutics (NASDAQ: NWBO) (NW Bio), a 

biotechnology company developing non-toxic DCVax®

 personalized immune therapies for solid 

tumor cancers, announced today that its 60-patient Phase I/II clinical trial of DCVax-Direct for all 

inoperable solid tumor cancers has been initiated at The University of Texas MD Anderson Cancer 

Center in Houston, Texas. 

DCVax-Direct offers a potential new treatment option for the many clinical situations in which 

patients' tumors are considered inoperable either because of the location or type of cancer, or 

because of the spread of multiple tumors. A large number of patients with lung, colon, pancreatic, 

liver, ovarian, melanoma, head and neck, and other cancers such as sarcomas face this situation 

today, and it carries a bleak prognosis. 

The excellent reputation and broad experience of the clinical trial team at MD Anderson makes 

them an ideal choice to initiate this study. It is anticipated that multiple other leading centers in 

both the US and UK will be joining as trial sites as well. Since the Company’s announcement of 

plans for this trial, NW Bio has received inquiries from both patients and medical centers across 

the country seeking to participate. 

The trial is expected to enroll groups or “cohorts” of patients with numerous different types of 

cancers, including pancreatic, colon, liver, melanoma, and various other cancers. 

The trial is a combined Phase I and II trial. In the Phase I stage, the trial will test various dose 

levels of DCVax-Direct. The trial will then proceed directly into the Phase II stage to test the 

efficacy of the DCVax-Direct treatment. The primary endpoint for measurement of efficacy will 

be tumor regression (i.e., shrinkage or elimination). 

As is standard with Phase I/II trials, this trial will not be blinded – the clinical results in patients 

will be seen as the trial progresses. Accordingly, it is anticipated that early results of the trial may 

be emerging throughout the remainder of 2013. Pre-clinical animal studies showed that injection of partially mature dendritic cells resulted in 

eradication of tumors -- both tumors that were injected with DCVax-Direct and tumors that were 

not injected (indicating a systemic immune response). In addition, after the animals’ tumors had 

been eradicated, when the animals were injected again with tumor cells later on, tumors failed to 

develop in these animals (indicating immune memory). 

The key to DCVax-Direct is the use of partially matured dendritic cells. These specially prepared 

dendritic cells have the ability to pick up tumor antigens (i.e., tumor biomarkers) from tumor cells 

inside the tumor after the dendritic cells are directly injected into the tumor. After picking up the 

antigens, these dendritic cells also have the ability to travel to lymph nodes and mobilize the 

immune system to attack tumors throughout the body which express these antigens. NW Bio 

holds strong patent coverage on both the manufacturing processes and the use of such partially 

matured dendritic cells. 

"We are very pleased to be teaming up with an institution with the depth, caliber and reputation of 

MD Anderson to initiate our highly novel, first-in-man Phase I/II trial of DCVax-Direct for all 

inoperable solid tumor cancers," Linda Powers, CEO of NW Bio noted. "After years of 

painstaking development, we could not ask for a better clinical partner to explore the potential of 

DCVax-Direct to achieve some tumor regression in patients with inoperable tumors.” 

According to the primary investigator, Dr. Vivek Subbiah, MD (Assistant Professor in the 

Department of Investigational Cancer Therapeutics, Division of Cancer Medicine, which is 

responsible for the institution’s early stage clinical trial programs), “Dendritic cell cancer vaccine 

therapy is a new and innovative therapeutic approach in our battle against cancer. Dendritic cell 

technologies have been advancing, and prior studies have shown encouraging results. Patients 

with inoperable tumors face very bleak prognoses, and have an urgent need for new treatment 

options. This innovative first-in-human study of NW Bio’s DCVax-Direct for inoperable tumors 

in multiple types of cancer is a crucial step forward for a new approach.” 

About Northwest Biotherapeutics 

Northwest Biotherapeutics is a biotechnology company focused on developing immunotherapy 

products to treat cancers more effectively than current treatments, without toxicities of the kind 

associated with chemotherapies, and on a cost-effective basis, in both the United States and 

Europe. The Company has a broad platform technology for DCVax dendritic cell-based vaccines. 

The Company’s lead program is a 312-patient Phase III trial in newly diagnosed Glioblastoma 

multiforme (GBM). GBM is the most aggressive and lethal form of brain cancer. The Company 

also previously received clearance from the FDA for a 612-patient Phase III trial in prostate cancer, 

and clearance from the FDA for Phase I/II trials in multiple other cancers. The Company also 

conducted a Phase I/II trial with DCVax for metastatic ovarian cancer together with the University 

of Pennsylvania.
