In February 2005, the monoclonal antibody Tysabri (natalizumab, Elan/Biogen Idec) was withdrawn from the market because three
patients taking it developed progressive multifocal leukoencephalopathy (PML). But the medication apparently helps some patients
with relapsing forms of multiple sclerosis. So in 2006, after further clinical trial work, the Food & Drug Administration
allowed the drug back on the market under a fairly complicated risk management plan created by the manufacturer and OK'd by
FDA.
The medication may be administered only to patients enrolled in the risk management plan and prescribed, distributed, and
infused only by providers registered with the program. That, according to Mary Willy, Ph.D., of FDA's Center for Drug Evaluation
& Research (CDER), makes Tysabri another of the 30 or so drugs with some version of these restraints, called Risk Minimization
Action Plans (RiskMAPs). And there are likely to be others as more is known about drugs' risks and benefits, and as genetic
science helps develop more personalized drugs.
Current drugs with RiskMAPs include clozapine (Clozaril, Novartis; FazaClo, Alamo), thalidomide (Thalimid, Celgene), lindane,
and isotretinoin (Accutane, Roche). The wide variety of RiskMAP protocols can in- clude patient screening; compliance documentation;
drug information for physicians, R.Ph.s, and patients; participation agreements; patient training and assessment; registration
of patients and providers; enhanced interaction precautions; mandated lab and other tests; and process measures.
In a public meeting last month in Rockville, Md., FDA and the Agency for Healthcare Research & Quality (AHRQ) heard from pharmacists
and others that RiskMAPs, while necessary, have caused complications in medication dispensing. Marcie Bough, Pharm.D., director
of federal regulatory affairs at the American Pharmacists Association, recommended that FDA create criteria to determine which
drugs warrant RiskMAPs and ensure that products are not placed unnecessarily in one of these programs. "Pharmacists must deal with and manage the growing number of these tools and programs, each with different structures and
often confusing requirements. This tends to focus pharmacists' interest and attention on administrative duties rather than
on the appropriate medication use," Bough said. Rather than the current product-by-product approach in building RiskMAPs,
"APhA recommends a system-based approach with use of standard tools based on the products' risk level."
APhA's testimony also called for RiskMAPs to be evaluated after they are implemented, at the practical level, by prescribers,
pharmacists, and patients. Evaluations, Bough said, should include actual health outcomes as well as documentation of patient
knowledge and compliance with the programs, and should look at how the programs would work in actual pharmacy practice.
Drug manufacturers should not be allowed to use RiskMAPs "as an opportunity for branding or for marketing advantage," said
Mark Gregory, R.Ph., of Kerr Drug, representing the National Association of Chain Drug Stores and the National Community Pharmacists
Association. He recommended that rather than have the manufacturers select the vendor for their RiskMAP development, FDA should
contract with a central vendor. He noted that several current RiskMAPs restrict distribution to certain pharmacies. "Restricted
distribution is not good for the patient and leads to fragmentation of care." Pharmacists, he said, are not reimbursed for
the extra time needed to dispense drugs with RiskMAPs, and manufacturers or payers should fund a system to compensate pharmacies
and other providers.
Nathan Thompson, R.Ph., of Johns Hopkins Home Care Group, representing ASHP, cautioned that if creation of RiskMAPs causes
a delay in getting the drug to pharmacists, it could cause a critical delay in getting the medication to patients.
Said Sandra Kweder, M.D., deputy director of the office of new drugs at FDA's CDER, "As the agency engages more and more in
this, we will see these taking a shape that better lends itself to the sort of transparency we all think would be a good thing."
FDA is accepting comments on the RiskMAPs through July 31. Further information is available at http:// http://www.fda.gov/cder/meeting/riskMAPs.htm.
