Laws recently passed or under consideration in state legislatures may offer some relief to physicians and patients dogged by the “step” or “fail-first” therapy protocols mandated by insurers, but until better clinical evidence is available to support treatment decisions and biosimilars reduce costs, clinicians must strategize to get patients through the step pathways as fast as possible.
Dr. Stephen B. Hanauer
Rheumatologists, gastroenterologists, and dermatologists all confront fail-first policies in their practices, particularly when prescribing the biologic agents that have been game changers in treating rheumatoid arthritis (RA), inflammatory bowel disease (IBD), and psoriasis, among other diseases.
In RA, for example, a patient might be required to fail a series of disease-modifying antirheumatic drugs (DMARDs), including methotrexate, before starting a biologic. In Crohn’s disease, patients might have to first fail on steroids and immunosuppressants.
Most clinicians consider cost concerns fair as a basis for insurance decisions. But they can also have strong rationales for making exceptions. This may mean starting patients on a biologic early, particularly those they deem unlikely to respond to first- or second-line treatments – which may be cheaper but are not necessarily safer.
Dr. David T. Rubin
In egregious cases, a patient already stable on a biologic who has changed insurance plans may be forced to go backwards in the treatment pathway, and fail first- and second-line therapies all over again before resuming – a process unlikely to be cost-effective in the long term, and also rife with ethical concerns, say clinicians.
“Making a patient fail to get a less toxic drug sort of violates our ‘do no harm’ principle,” Dr. Stephen B. Hanauer, medical director of the Digestive Health Center at Northwestern University, Chicago, said in an interview.
“I always say that if biologics cost a dollar, we’d be using them for everybody. If you take away the steroids and the immunosuppressants, these are very safe drugs for IBD, far safer than steroids – but steroids are cheap,” Dr. Hanauer said.
And with some debilitating disease presentations, such as severe Crohn’s, “being told that we have to try conventional therapies and the patient has to fail them can mean putting the patient through progression of their disease, and suffering,” Dr. David T. Rubin, codirector of the Digestive Diseases Center at the University of Chicago, said in an interview. “We really struggle with this.”
Dr. Joseph S. Eastern
Dr. Joseph S. Eastern, a dermatologist practicing in Belleville, N.J., said his specialty faces similar challenges with step therapy. “Dermatologists as a group are pretty risk averse. When given the opportunity, we do an excellent job of prescribing conventional medications, ultraviolet therapy, and biologics in the most cost-efficient possible way,” he said in an email.
Yet “third-party payers tell us, for example, that a patient must fail methotrexate before we can use a biologic, when the whole advantage of biologic therapy for many of these patients is the avoidance of organotoxicity and other serious risks.”
As a result, Dr. Eastern said, “I write a lot more vehement letters to payers about the biologics these days.”
Choice vs. cost
Rheumatologists are among the clinicians most affected by fail-first and step therapy mandates, as the diseases they treat – particularly RA – are the most established indications for biologic therapies, and for which the largest number of these are approved.

Though Medicare and Medicaid allow physicians considerable leeway, private insurers often tightly circumscribe the timing and choice of biologics in RA. As insurers’ first-choice biologic drug changes frequently, and varies from plan to plan, a patient who is stable on one agent might be asked to switch to another, a phenomenon known as nonmedical switching.
Insurers are seldom transparent about their reasons for establishing certain biologic drugs as their go-to agents, clinicians say, while making it difficult for physicians to prescribe others. “There’s a tremendous amount of discounting going on that we are oblivious to as physicians. I’ve seen situations where drug A is the first one you have to use this month and the next month, drug C,” said Dr. Norman Gaylis, a rheumatologist practicing in Aventura, Fla.
Attempting to start a patient on a nonpreferential biologic will generate paperwork and delays, Dr. Gaylis said, which can cost patients valuable time. “There’s a window of opportunity to treat these diseases, and by creating a step therapy pathway we’re closing the window at least partially.”
“As an example, rituximab in most payer plans is not tiered as a first-line biologic treatment option despite the fact that there are frequent scenarios where the clinical and serological presentation of a patient would suggest it to be preferable as a first-line treatment choice over an anti-TNF [tumor necrosis factor],” Dr. Gaylis said.
