Would your patient benefit from a monoclonal antibody?

The challenges associated with MAbs

MAbs can be expensive (TABLE 2),⁴⁵ some prohibitively so. On a population scale, biologics account for around 40% of prescription drug spending and may cost 22 times more than small-molecule drugs.⁴⁶ Estimates in 2016 showed that MAbs comprise $90.2 billion (43%) of the biologic market.⁴⁶

MAbs also require prior authorization forms to be submitted. Prior authorization criteria vary by state and by insurance plan. In my (ES) experience, submitting letters of medical necessity justifying the need for therapy or expertise in the disease states for which the MAb is being prescribed help your patient get the medication they need.

Expect to see additional MAbs approved in the future. If the costs come down, adoption of these agents into practice will likely increase.
