Constructor calls can be made with duk_new(), e.g. as follows:

duk_push_global_object(ctx);
duk_get_prop_string(ctx, -1, "Proxy");
/* push target */
/* push handler */
duk_new(ctx, 2);  /* [ global Proxy target handler ] -> [ global result ] */
duk_remove(ctx, -2);  /* remove global -> [ result ] */
/* stack now contains result from constructor */

more..
//heres a snipped of my working code
duk_push_global_object(ctx);
iglobal = duk_get_top(ctx) -1;
//..do work to put handler and target on global object, Proxy is builtin on global..
rc = duk_get_prop_string(ctx,iglobal,"Proxy");
rc = duk_get_prop_string(ctx,iglobal,"target");
rc = duk_get_prop_string(ctx,iglobal,"handler");
duk_new(ctx,2); /* [ global Proxy target handler ] -> [ global result ] /
//duk_remove(ctx, -2); /
remove global -> [ result ] */ //for now, leave global object on stack
duk_put_prop_string(ctx,-2,"proxy"); //add var proxy name, and put on global object
duk_eval_string(ctx,"proxy.foo = 'yoda';"); //use proxy object
