Again, cost is the only barrier preventing biologics from being a 1st line treatment for UC...
Well, yes and no.
When we talk about
biologics, we tend to lump them all together. But we should probably distinguish the anti-TNFS from the newer ones like Entyvio and Stelara.
We should also distinguish mild UC from moderate-to-severe UC.
In mild UC, the first line of treatment is mesalamines, regardless of cost (ie, even if anti-TNFs were as cheap). Entyvio and Stelara are showing really good effectiveness AND really good side effect profiles (better than anti-TNFs), so it's possible that with a couple years more data, those could theoretically be first line treatments even for mild UC - IF cost were no issue. In mild UC, the anti-TNFs would not supplant mesalamines for first line treatment because of their risk of side effects being greater making them not worth the risk.
But in moderate to severe UC, yes, biologics should/would be 1st line treatment and cost is the main reason they sometimes aren't. At the conference two "famous" researchers debated whether Remicade or Entyvio should be the 1st line treatment for moderate to severe UC. Remicade has stronger data and more history, but more risk of side effects. Entyvio is very promising but doesn't quite have the data and history, but its side effects appear less than anti-TNFs.
They also said that as more and more data has been compiled, that the recommendations of using monotherapy with azathioprine or 6mp are going away. Aza/6mp have only modest benefit by themselves, but have risks of serious side effects. Just not worth the tradeoff. But they do still strongly recommend aza/6mp with an anti-TNF, because they help the anti-TNF work better, have better pharmacodynamics, and prevent antibody formation.
