How use static_cast with double casting

How can I use static_cast with casting types like that:

CString response;
resultData = (void *) (const char *) response;

where result data is type void *&.

I tried to do to this in following way:

resultData = static_cast<(void*)(const char*)>(response);
resultData = static_cast<void*>(static_cast<const char*>(response));

but it doesn't work.

Do you have any ideas?
