Biologics – Birth of a new era of precision management in asthma

An estimated 10% to 20% of patients with severe uncontrolled asthma do not respond to maximal best standard treatments, leading to substantial health-care costs. A paradigm shift is now underway in our approach to the care of these patients with the emergence of novel biologics targeting the complex and interconnected inflammatory pathways in asthma that result in a diverse profile of asthma endotypes and phenotypes (Fig 1).

Current FDA-approved biologics primarily target patients with a T2 high phenotype (Table1).

Dupilumab binds to the alpha unit of the IL-4 receptor and blocks both IL-4 and IL-13. It shows potential efficacy in patients with T2 high asthma with or without eosinophilia but has not yet received FDA approval.

Multiple newer biologics are currently in development (Table 2).

Pulmonologists need to get familiar with the logistics of administration of these novel agents. The two common methods of administering biologics are (1) buy and bill – where the provider buys the drug directly from the distributor; and (2) assignment of benefits (typically administered by a Pharmacy Benefit Manager) - specific dose of the medication is shipped to the physician’s office and physician only bills for the administration. CPT and J codes are shown in Table 1.
