Safety and Immunogenicity of CHP-HER2 and CHP-NY-ESO-1 Protein With OK-432 in Antigen-Expressing Cancers
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Mixed cancer vaccines, CHP-HER2 protein and CHP-NY-ESO-1 protein, are to be studied to evaluate the safety and immune responses in patients who are positive either or both antigens. Nine patients will be enrolled, who are refractory to standard therapies for cancer or at high risk to relapse. CHP-HER2 and CHP-NY-ESO-1 are subcutaneously given on bimonthly basis, together with OK-432(Picibanil) as an immunoadjuvant. Six doses will be given. Toxicity profiles will be monitored, and antigen specific humoral anad T cell responses will be described.
