Trikafta coverage

Hi. I'm on Trikafta and since my job changed prescription plans, my Trikafta is a 4000.00 copay. I have good health insurance and had Benecard for my prescriptions and only paid 10.00. Now I am looking around for co pay assistance programs to help with the cost. I live in NJ. Is anyone having this issue and how do you handle this?
