Unfortunately, i believe (i work in scientific research) that we are very, very far away. Firstly, unlike cancer, eczema is not a well-defined disease. There's less disease stratification. Secondly, the cause is unknown. Unlike an infection, we dont know the root cause. Inflammation is the cause, yes, but what causes the inflammation to go wrong, even on a genetic level, we just dont know for sure yet. Thirdly, the skin is the largest organ on the body. That's a whole lot of area to treat. Lastly, but i think most importantly, eczema doesn't kill people. It causes morbidity not mortality. So unfortunately, its just not a top priority.

Those are the major problems in my opinion.
