Rare Diseases and Orphan Products: Accelerating Research and Development C Medicare Part D Coverage and Reimbursement of Orphan Drugs Laura Faden and Haiden Huskamp* INTRODUCTION Given the small potential market for medications that treat rare conditions, pharmaceutical manufacturers may have reduced incentives to develop new medications for rare diseases. To increase incentives for manufacturers, the Orphan Drug Act (P.L. 97-414) provides the following provisions for drugs that receive an orphan drug indication1 from the U.S. Food and Drug Administration (FDA): a 7-year period of market exclusivity, a tax credit of 50 percent of the cost of conducting clinical trials, eligibility for federal research grants, and a waiver of user fees (21 USC 360bb, OIG, 2001). However, health plan coverage and reimbursement also influence a pharmaceutical firm’s decisions to invest in the development of a drug or biologic for a rare disease. The purpose of this report is to examine stand-alone Medicare Part D prescription drug plan (PDP) coverage of a set of drugs and biologics that * Laura Faden., M.P.H., is a doctoral student in the Harvard University Program in Health Policy.

Rare Diseases and Orphan Products: Accelerating Research and Development treat rare diseases or conditions—which we will refer to collectively as “orphan drugs”—in the Medicare population. This report does not address Medicare coverage and reimbursement of medical devices. We focus on the Medicare population because the program covers approximately 15 percent of the U.S. population, including adults who have a disabling rare condition and who have Medicare coverage based on their qualification for Social Security Disability Insurance (SSDI). Furthermore, data on Medicare prescription drug coverage and reimbursement are more readily available than similar data from Medicaid and private plans—because Medicare is a public, federal program, the data are public and centrally collected. There have been no comprehensive studies of Medicare PDP coverage and reimbursement of orphan drugs. In 2005, the National Organization for Rare Disorders (NORD) conducted a similar study that examined coverage of orphan drugs in 10 national Medicare Part D plans (NORD, 2006). This report extends the NORD report by including drugs approved since 2005 and by analyzing coverage of all Medicare prescription drug plans. Furthermore, this report goes beyond the NORD analysis, which only analyzed plan coverage, by also analyzing factors that may reduce access to covered drugs (i.e., formulary tier placement, utilization management).2 Medicare Beneficiaries Medicare, which was created by the Social Security Act of 1965, is a federally administered health insurance program for people who are 65 years of age or older or who qualify for SSDI. There is typically a two-year waiting period before people who qualify for SSDI can receive Medicare benefits. Congress has waived that requirement for people with end-stage renal disease or Lou Gehrig’s disease. As of January 2010, Medicare covers 46 million Americans, 17 percent of whom are under 65 years and are permanently disabled (KFF, 2010c). Almost half (47 percent) of Medicare beneficiaries have low income (below 200 percent poverty), and 7 million beneficiaries meet income and asset criteria to quality for Medicaid—these beneficiaries are known as “dual-eligibles.” Among the Medicare population, there is a high prevalence of comorbid conditions (44 percent suffer from three or more chronic conditions), and 29 percent have a cognitive or mental impairment (KFF, 2010c). It is not known how many Medicare beneficiaries have a rare disease or, conversely, what proportion of people with a rare disease is covered by Medicare. However, the Social Security Compassionate Allowances program— 2 Although the NORD report notes the tier placement and utilization management tools used for each drug, the authors do not provide any analysis of these aspects of drug coverage.

Rare Diseases and Orphan Products: Accelerating Research and Development which guarantees immediate SSDI benefits for people who suffer from certain conditions—covers many rare diseases (Social Security Online, 2010). Currently, more than 27 million Medicare beneficiaries are enrolled in a Medicare prescription drug plan, two-thirds of whom are enrolled in a stand-alone PDP (KFF, 2009d, 2010b).3 In 2009, 36 percent of these beneficiaries received low-income subsidies (LIS) that cover their premiums and deductibles; LIS beneficiaries are responsible only for a small copayment that is determined by their income level (KFF, 2009a). Dual-eligibles and those eligible for Supplemental Security Income cash assistance are automatically eligible for LIS, and other low-income beneficiaries can apply for the subsidies. All LIS beneficiaries are enrolled in plans that have monthly premiums below the benchmark premium amount established for each region (hereafter referred to as “benchmark plans”). Medicare Prescription Drug Plans Until 2006, Medicare did not cover outpatient prescription drugs. It covered hospital and physician services (Part A and B), which included coverage of inpatient drugs and drugs administered by a physician (e.g., infusions). The Balanced Budget Act of 1997 created an option for Medicare beneficiaries to receive insurance coverage from private health plans that contract with Medicare (Part C)—these plans are currently referred to as “Medicare Advantage Plans.” The Medicare Prescription Drug Improvement and Modernization Act of 2003 created the Medicare Part D program, a voluntary drug benefit that is administered through private health plans or pharmaceutical benefit managers. As of January 1, 2006, Medicare beneficiaries could voluntarily enroll in either a stand-alone PDP or a Medicare Advantage plan with prescription drug coverage (MA-PD). Dual-eligibles are automatically enrolled in a benchmark plan. The legislation does not require PDPs to have uniform cost sharing requirements or formulary design. However, PDPs are required to offer a plan that is at least actuarially equivalent to a standard benefit package as determined by the Centers for Medicare and Medicaid Services (CMS) (CMS, 2010). In 2010, the standard benefit package is $310 deductible; 25 percent coinsurance up to $2,830 of total drug costs; 3 Of the remaining Medicare beneficiaries not covered by a Part D plan—approximately 19 million—most have drug coverage, either through a retiree drug plan (through an employer or union) or another form of drug coverage (e.g., Veterans Affairs, Indian Health Services, state pharmacy assistance programs, employer benefits for active workers, etc.). Approximately 10 percent of beneficiaries have no prescription drug coverage (KFF, 2009d, 2010b).

Rare Diseases and Orphan Products: Accelerating Research and Development no coverage from $2,830 to $6,330 of total drug costs—a coverage gap that is commonly referred to as the “doughnut hole,” which, starting in 2010, will be partially subsidized (beneficiaries will receive a $250 rebate);4 and 5 percent coinsurance, or a flat copayment of $2.50 for a generic drug and $6.30 for a brand drug, above $4,550 out-of-pocket expenses (i.e., catastrophic out-of-pocket spending limit) with no maximum limit on out-of-pocket expenses. In addition, CMS requires that PDP and MA-PD formularies include at least two drugs in every drug class5 and all, or substantially all, drugs in the following six “protected” therapeutic categories: antidepressants; antipsychotics; anticonvulsants; immunosuppressants (to prevent rejection of organ transplants); antiretrovirals (for the treatment of infection by retroviruses, primarily HIV); and antineoplastics (only those chemotherapy drugs that are generally are not covered under Medicare Part B) (CMS, 2010). Even with these requirements, PDPs and MA-PDs have a considerable amount of flexibility in formulary design. First, plans decide whether or not to cover a drug. Second, plans can use a tiered formulary structure to create financial incentives for beneficiaries to choose lower-cost or preferred drugs. In 2010, approximately three-fifths of plans have the following fourtier structure (KFF, 2009c). Tier 1: generic drugs Tier 2: preferred brand-name drugs Tier 3: nonpreferred brand-name drugs Tier 4 (“specialty tier”): specialty drugs6 Each tier has a different cost sharing requirement—most plans assign a flat copayment to the first three tiers and a coinsurance to the specialty tiers (although a growing number of plans are requiring a coinsurance for the first three tiers) (KFF, 2009c). Almost all (94 percent) of plans have a 4 The Patient Protection and Affordable Care Act of 2010 (P.L. 111-148) included provisions to reduce cost sharing in the doughnut hole. Starting in 2011, Medicare and manufacturers will phase in subsidies for generic and brand drugs with the goal of reducing out-of-pocket expenditure in the doughnut hole in 2010 to the same 25 percent coinsurance that applies to costs below the lower threshold of the coverage gap. 5 The U.S. Pharmacopeia has developed a therapeutic classification system that serves as a guideline for Part D formularies. Model guidelines are publicly available: see http://www.usp.org/pdf/EN/mmg/modelGuidelinesV4.0WithFKDTs.pdf. 6 CMS guidelines stipulate that drugs placed on the specialty tier must cost at least $600 per month and prohibit enrollees from requesting cost sharing exceptions for specialty drugs (CMS, 2009b).

Rare Diseases and Orphan Products: Accelerating Research and Development specialty tier (KFF, 2009c).7 In 2010, the specialty tier coinsurance ranges from 25 to 33 percent of the full cost of the drug (KFF, 2009c). In addition to coverage decisions and tiered formularies, a third way in which plans influence prescription drug utilization is by employing utilization management tools such as prior authorization (PA) requirements, step therapy (ST) requirements, and quantity limits (QL). PA requirements create an administrative barrier to accessing a drug—a patient or provider must follow a certain procedure, created by the plan, to request coverage of the drug and then await the plan’s approval of coverage. ST requirements establish a chronological course of recommended treatments for a condition that must be tried before coverage of the drug is approved. QL requirements set explicit criteria for the quantity of a drug that will be covered during a given period of time. METHODS Medicare Part D Plans Characteristics and Orphan Drug Coverage We used the CMS Formulary and Pharmacy Network Information File (January 2010 quarterly release) to determine the coverage, tier placement, and utilization management requirements for each orphan drug. We classified drug plans as stand-alone drug plans (PDPs) and MA-PD plans.8 Within PDPs, we identified national plans (i.e., plans offered in every region of the country) and benchmark plans. National plans were identified by contract number (CMS, 2009b), and benchmark plans were identified using the regional premium limits (CMS, 2009a). We calculated the “plan coverage rate” for a particular drug as the percentage of plans that cover the drug. Similar to the NORD report (NORD, 2006), we categorized each drug by level of coverage rate, which we classified as the following: No or low coverage: <25 percent plan coverage rate Low coverage: 25-49 percent plan coverage rate Medium coverage: 50-74 percent plan coverage rate High coverage: 75-99 percent plan coverage rate Complete coverage: 100 percent plan coverage rate We also examined tier placement and utilization management among drugs covered by PDPs. For each drug we calculated the “tier placement 7 This excludes plans that offer the standard benefit package (i.e., plans that have no tiering). 8 MA-PDs include both regional and local plans. However, for the analyses we removed duplicate MA-PDs by including each unique contract and plan combination only once.

Rare Diseases and Orphan Products: Accelerating Research and Development rate” as the percentage of plans that cover that drug on a given tier. For example, if 20 percent of the plans that cover a drug have placed that drug on tier 4, the drug has a tier 4 placement rate of 20 percent. The tiers range from one to four. A few plans have more than four tiers—for these plans we included all tiers greater than four in the tier 4 category.9 Similarly, we examined rates of step therapy requirements, quantity limits, and prior authorization requirements (“utilization management rate”).10 We categorized each covered drug by the rate of tier placement and use of utilization management, which we classified into the following categories: No or low placement (or use): <25 percent of plans Low placement (or use): 25-49 percent of plans Medium placement (or use): 50-74 percent of plans High placement (or use): 75-99 percent of plans Complete placement (or use): 100 percent of plans In terms of beneficiary access to drugs, a higher plan coverage rate will likely improve access, whereas a higher utilization management or tier 4 placement rate may pose barriers to access. These categories are subjective and were created only to simplify the interpretation of the results for all drugs along the three dimensions of access (i.e., plan coverage, tier placement, and utilization management). Therefore we also report the raw rates. 9 For the purposes of this report, we refer to tiers 4-6 as “tier 4” and assume that tier 4 is equivalent to a specialty tier. However, given the heterogeneity of the PDPs’ formulary structures, this assumption does not hold for all plans. As previously noted, three-fifths of the plans have a four tier structure—for these plans tier 4 is the specialty tier (CMS, 2009b). Some plans have no tiers (11 percent) or fewer than four tiers (7 percent)—for the latter, the specialty tier may actually be tier 3. Also, 21 percent of the plans have more than four tiers—for these plans, tier 4 may not be a specialty tier but rather a nonpreferred brand tier (CMS, 2009b) or a tier for injectible drugs (KFF, 2010a). Therefore, by collapsing tiers 4-6 and labeling this as a specialty tier, we may be misclassifying up to 28 percent of the plans. However, this misclassification may have a negligible effect in terms of concerns about beneficiary cost sharing because a large share (34 percent) of PDPs now use coinsurance rates for nonpreferred brand tiers (CMS, 2009b) and these coinsurance rates may actually be higher than specialty-tier coinsurance rates. Likewise, cost sharing for drugs placed in an injectible tier is also likely to be high because these drugs are quite expensive. 10 Note that for these analyses, the rates are based on only the number of plans that cover each drug (i.e., the denominator is different for each drug). Since each drug is associated with multiple entries in the National Drug Code (NDC) directory, a drug may appear on multiple tiers of a plan’s formulary (e.g., both the brand and generic version are covered, but the generic is on lower tier). For the purposes of our analyses, we assign drugs to the lowest tier on which they appear. A plan is counted as having a utilization management tool for a drug if the tool is applied to at least one of the covered NDCs associated with the drug.

Rare Diseases and Orphan Products: Accelerating Research and Development To determine if coverage policies differed by type of plan, we repeated these analyses for several subgroups of plans: all PDPs, benchmark PDPs, national PDPs and MA-PDs. Although we present data on all analyses, we focus on the analyses of all PDPs in the results and discussion sections. List of Orphan Drugs We created a list of drugs that were approved by the FDA with an orphan indication between 1983 and December 2008. We included only drugs approved prior to 2009 in order to provide adequate time for marketing and plan coverage decisions. We included only outpatient drugs (i.e., not covered by Medicare Part B as of July 2010) that have an approved orphan indication relevant to the Medicare population (i.e., not for a pediatric indication11) and that have not been discontinued or withdrawn. Our list excludes drugs that are covered by Medicare Part A or B and blood products. We also excluded drugs that are available on the market (for other FDA-approved indications) and that have been granted an orphan designation but have not yet received FDA approval for an orphan indication. Lastly, we excluded drugs for the treatment of rare diseases or conditions that appear in Medicare compendia unless the FDA has approved the drugs for the same orphan indication (see Chapter 6 of this report). The National Drug Codes (NDCs) for each drug were obtained from First Data Bank (FDB), which was up-to-date as of January 2010. We noted which drugs are available in generic form and which are biologics versus new chemical entities. RESULTS List of Orphan Drugs Ninety-nine orphan drugs met our inclusion criteria (see Addendum Table C-A1). Drugs are listed in chronological order of the date of approval of the first orphan indication relevant to the Medicare population (some drugs have multiple relevant orphan indications). Twenty-nine (29 percent) of the drugs are available in generic form and eleven (11 percent) are biologics. Medicare Plan Characteristics—Part D and Medicare Advantage Plans In 2010, there are 1,620 stand-alone PDPs and 2,418 MA-PDs. Of the PDPs, 1,295 (77 percent) are national plans and 398 (23 percent) are 11 We performed a separate analysis of Medicare Part D coverage of orphan drugs with only a pediatric indication orphan approval. See Addendum Tables C-A3 and C-A4.

Rare Diseases and Orphan Products: Accelerating Research and Development benchmark plans. The 1,295 national plans represent 12 plan sponsor organizations, 26 unique contracts, and 88 unique formularies (a sponsor may use the same formulary for multiple plans). The average monthly premium is $46.39 (range: $1.50 to $120.20; standard deviation: $19.75) (see Table C-1). More than half (60 percent) of the plans have deductibles. The median deductible for all plan types is $310.00 (range: $10.00 to $310.00). Benchmark plans and nonnational plans are more likely to have a deductible and to have a higher deductible than nonbenchmark and national plans. Compared to stand-alone PDPs, MA-PDs have a lower average premium and are less likely to have a deductible. Medicare Plans’ Coverage of Orphan Drugs— Stand-Alone PDPs and MA-PDs The coverage rate (percentage of plans covering a drug) for orphan drugs among Medicare prescription drug plans is high. On average, an orphan drug is covered by 84 percent (standard deviation: 24 percent) of stand-alone PDPs. Table C-2 shows a breakdown of coverage rate category by plan type. Of the 99 drugs, 44 (44 percent) are covered by all 1,620 PDPs (i.e., complete coverage category). An additional 29 drugs (29 percent) are covered by at least 75 percent of the plans (i.e., high-coverage category). Table C-2 shows that 19 (19 percent) of the drugs fall into the medium-coverage category (i.e., only covered by 50-75 percent of plans) and that 7 (7 percent) are covered by less than half of the plans (i.e., no or very low coverage and low-coverage categories). As of January 2010 4 drugs are not covered by any PDP: citric acid, glucono-delta-lactone, and magnesium car- TABLE C-1 Average Premium and Use of Deductible for Different Types of Medicare Prescription Drug Plans (99 drugs) N Average Premium (std. dev.) % with Deductiblea All stand-alone PDPs 1,620 46.39 (19.75) 60 Benchmark PDPs 398 28.70 (5.69) 94 Nonbenchmark PDPs 1,222 52.15 (19.27) 49 National PDPs 1,295 46.70 (20.14) 57 Nonnational PDPs 325 45.15 (18.07) 72 MA-PDs 2,418 20.12 (18.81) 23 a The median deductible across all plan types is $310.

Three other drugs—lodoxamide tromethamine (Alomide Ophthalmic Solution), tinidazole (Tindamax), and metronidazole topical (Metrogel)—are covered by 45 to 50 percent of PDPs (see Table C-3). As explained in the note for the table, a search of formularies conducted in late spring 2010 found a few plans had initiated coverage of Galzin and Renacidin Irrigation. Overall, MA-PD plans have slightly better coverage of orphan drugs than stand-alone PDPs. Compared to PDPs, the percentage of drugs falling into the no-very low and low-coverage categories is slightly lower among MA-PDs (4 percent in MA-PDPs versus 7 percent in PDPs). On average, an orphan drug is covered by 87 percent (standard deviation: 22 percent) of MA-PDPs, compared to 84 percent of stand-alone PDPs. Within PDPs, there is some variation in coverage rates between benchmark and nonbenchmark plans, with nonbenchmark plans having slightly higher coverage rates. On average, an orphan drug is covered by 83 percent (standard deviation: 26 percent) of benchmark plans and 85 percent (standard deviation: 24 percent) of nonbenchmark plans. The benchmark plans have a higher percentage of drugs that fall within the no-very low

Rare Diseases and Orphan Products: Accelerating Research and Development and low-coverage categories (11 percent in benchmark versus 6 percent in nonbenchmark plans). There is considerably more variation in coverage rates between national and nonnational plans, with national plans having higher coverage rates. On average, an orphan drug is covered by only 77 percent (standard deviation: 32 percent) of nonnational plans, compared to 86 percent (standard deviation: 24 percent) of national plans. Within nonnational plans, almost a quarter (23 percent) of the drugs are classified as having a no-very low or low-coverage rate, compared to only 4 percent of drugs within national plans. Aside from the four drugs covered by no PDPs, no other drug is covered by less than 50 percent of the national plans. Conversely, 19 of the 95 covered drugs are covered by less than 50 percent of the nonnational plans. Formulary Tier Placement by Stand-Alone PDPs The orphan drugs are commonly placed on high cost sharing tiers. Table C-4 shows the tier 4 placement rate by plan type. For these analyses, and the utilization management analyses below, we excluded the four drugs not covered by any plan. Of the 95 remaining drugs, 84 (88 percent) are placed on tier 4 or higher by at least one PDP. Twenty-eight (29 percent) are placed on tier 4 by at least 75 percent of the plans (i.e., high tier 4 placement), and another 15 (16 percent) are placed on tier 4 by at least 50 percent of the plans (i.e., medium tier 4 placement). Utilization Management Tools Used by Stand-Alone PDPs PDPs rarely use step therapy to manage orphan drugs. ST is used by at least one plan only for 18 (19 percent) of the covered orphan drugs. Of these 18 drugs, half (9) have a ST use rate of less than 10 percent. The drug with the highest use of ST—interferon beta-1b—is given ST requirements by almost one-quarter (23 percent) of PDPs. The use of quantity limits to manage utilization of orphan drugs is more common among PDPs than the use of ST, although most plans do not use quantity limits for these drugs. QLs are used by at least one plan for 57 (60 percent) of the covered drugs. Twenty-seven (28 percent) of these drugs have QL use rates greater than 20 percent, and an additional 4 drugs (4 percent) have QL use rates greater than 50 percent (interferon beta-1a, lidocaine patch, raloxifene, and modafinil). Prior authorization is the most widely used form of utilization management employed by PDPs. Table C-5 shows PA rates by plan type. PA is used by at least one plan for 80 (84 percent) of the covered orphan drugs. Thirty-three (35 percent) of the drugs are given a PA requirement by at least

Remicade, which received a pediatric orphan approval for the treatment of pediatric Crohn’s disease, is also approved for an adult orphan indication and was therefore included in a previous list of drugs. The drugs are sorted by the exclusivity date (i.e., date of approval of orphan indication) for first orphan approval with a relevant indication. Drugs with multiple orphan designations often have different exclusivity dates associated with each approved indication. The text for some indications has been abbreviated.
