Does anyone know of an inpatient program for severe atopic dermatitis?

My son has had severe dermatitis for approx 5 years and has progressed through all the standard topical prescription options. He has also tried Dupixent and had to stop due to an eye reaction. He also tried off label drug for rheumatoid arthritis and had to stop. I'm looking for an inpatient program and can't find any info. Any help would be appreciated.
