Would your patient benefit from a monoclonal antibody?
These unique agents may be the answer when other treatments fail or are intolerable for patients with asthma, atopic dermatitis, hyperlipidemia, osteoporosis, or migraine headaches.
PRACTICE RECOMMENDATIONS
› Consider anti-immunoglobulin E, anti-interleukin 5, or anti-interleukin 4/interleukin 13 for patients with moderate-to-severe asthma and type 2 airway inflammation. B
› Consider dupilumab for patients with moderate-to-severe atopic dermatitis (with or without topical corticosteroids), or when traditional oral therapies are inadequate or contraindicated. B
› Consider proprotein convertase subtilisin/kexin type 9 inhibitors for patients with heterozygous familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease when maximally tolerated statins or ezetimibe have not lowered low-density lipoprotein cholesterol levels far enough. A
Strength of recommendation (SOR)
A Good-quality patient-oriented evidence
B Inconsistent or limited-quality patient-oriented evidence
C Consensus, usual practice, opinion, disease-oriented evidence, case series
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.
