Clinical Trial and Option Agreement [Abstract]
Clinical Trial and Option Agreement [Text Block]	11. Clinical Trial and Option Agreement During September 2014, Asterias entered into a Clinical Trial and Option Agreement (the “CRUK Agreement”) with Cancer Research UK (the “Charity”) and Cancer Research Technology Limited, a wholly-owned subsidiary of the Charity, pursuant to which the Charity has agreed to fund Phase I/IIa clinical development of Asterias’ AST-VAC2 product candidate. Asterias will, at its own cost, complete process development and manufacturing scale-up of the AST-VAC2 manufacturing process and will transfer the resulting cGMP-compatible process to the Charity. The Charity will, at its own cost, manufacture the clinical grade AST-VAC2 and will carry out the Phase I/IIa clinical trial of AST-VAC2 in cancer patients both resected early-stage and advanced forms of lung cancer. Asterias will have an exclusive first option to obtain a license to use the data from the clinical trial. If Asterias exercises that option it will be obligated to make payments upon the execution of the License Agreement, upon the achievement of various milestones, and then royalties on sales of products. In connection with the CRUK Agreement, Asterias sublicensed to CRUK for use in the clinical trials and product manufacturing process certain patents that have been licensed or sublicensed to Asterias by third parties. Asterias would also be obligated to make payments to those licensors and sublicensors upon the achievement of various milestones, and then royalties on sales of products if AST-VAC2 is successfully developed and commercialized.
