DCVax®-Direct Phase II Trial Preparations and Manufacturing Expansion Underway

July 16, 2014

Northwest Biotherapeutics (NW Bio), a biotechnology company developing DCVax® personalized immune therapies for solid tumor cancers, announced today that the Phase I portion of the Company’s Phase I/II DCVax-Direct clinical trial has completed its 36-patient target recruitment, and the Company is now underway with preparations for the Phase II portion of this trial, as well as expansion of DCVax-Direct manufacturing.

The Phase I/II trial is testing the safety and activity of DCVax-Direct in various types of cancer. The Phase I portion of the trial has involved testing of 3 different dose levels, and a diverse range of cancers.  The patients enrolled in Phase I will continue to receive treatments in accordance with the protocol.

With the closing of Phase I, the Company is now preparing to initiate the Phase II portion of the trial.  This second part of the Phase I/II study will target 24 or more patients in selected cancers.  Additional trial sites are being brought on to facilitate and expedite enrollment.

The Company and its manufacturing partner, Cognate BioServices, are also expanding the manufacturing capacity for DCVax-Direct.  During the last two years, in addition to manufacturing the DCVax-Direct products for the clinical trial, Cognate has undertaken development work for the DCVax-Direct program, and the automated system used in certain key stages of DCVax-Direct production, in order to build the foundation for this expansion of manufacturing capacity.

“It is very gratifying to reach this important milestone in the Phase I portion of the Phase I/II DCVax-Direct clinical trial,” commented Linda Powers, CEO of NW Bio.  “We are looking forward to proceeding with Phase II, with anticipated expansion of the clinical trial sites and expanded manufacturing capacity and automation efficiencies.”
