In medical usage 'non-' + 'response' straightforwardly yields 'no reaction to treatment', a regular compositional use.

Etymology

Nonresponse comes from non- 'not' and response 'answer', and a helpful image is to think of the body as being asked to 'reply' to a treatment. If the body gives no answer or reaction, there is a nonresponse, which is why the word means a failure to improve or react to medical treatment.
