There is no known cure for kidney disease. So any sign that eGFR is going up has to be only because of Apabetalone.
ALP: this too can't really be easily lowered. But if the patient with the eGFR rising also has ALP falling...then that would suggest Apabetalone is working as we expect it to.
I asked RVX these questions, but they gave me a "can't answer those questions" comment.
