The High List Price and What It Means
Koselugo (selumetinib) is a targeted therapy used to treat pediatric patients with Neurofibromatosis Type 1 (NF1) who have symptomatic, inoperable plexiform neurofibromas (PN). As a specialized rare disease medication, it carries a very high list price. According to reports from 2020, the wholesale acquisition cost (WAC) averaged around $12,500 per month for an average patient. However, the actual price paid by a patient can differ dramatically based on their insurance plan, individual dosage requirements, and access to financial assistance programs.
The medication's dosage is based on a patient's body surface area, meaning the number of capsules required per month can vary from one patient to another. This means the total annual cost can range considerably. For example, a hypothetical patient with a Body Surface Area (BSA) of 1.12 m2 on the recommended dosage may have an annual list price exceeding $268,000.
Factors That Influence Your Out-of-Pocket Cost
Several factors determine a patient's final expense for Koselugo. It is important for families to investigate each of these areas to understand their potential financial responsibility.
Insurance Coverage
- Commercial Insurance: For those with private commercial insurance, coverage for Koselugo often requires a prior authorization process. Many plans place Koselugo on a high specialty drug tier, which means higher copayments and coinsurance for the patient. The Alexion Koselugo CoPay Program may help eligible patients with commercial insurance reduce their out-of-pocket costs to as little as $0, subject to an annual maximum.
- Medicare: Medicare prescription drug plans often list Koselugo on Tier 5, the highest tier, which involves the highest out-of-pocket expenses. Depending on the stage of coverage (deductible, initial coverage, coverage gap, catastrophic coverage), a patient's cost can change. For example, in the catastrophic stage, Medicare covers most of the cost, leaving a small copay.
- Medicaid: Medicaid programs vary by state. Many require prior authorization and have specific coverage criteria. Patients on federal or state-funded healthcare plans, including Medicaid, are typically not eligible for manufacturer-sponsored copay programs.
Dosage and Body Surface Area
As mentioned, Koselugo dosage is based on a patient's body size. A pediatric patient who weighs more will likely require a higher daily dosage, which directly increases the overall monthly cost. A healthcare provider can calculate the specific daily requirement based on the patient's body surface area and the prescribed 25 mg/m2 dosage.
Manufacturer and Nonprofit Financial Assistance
To help alleviate the financial burden, several support systems are available to patients and caregivers.
Alexion OneSource™ Program
Alexion, the company that provides Koselugo, offers a free, personalized patient support program called OneSource™. This program is designed to help families navigate the complexities of their health insurance and financial obligations. Services from OneSource™ include:
- Case Management: Dedicated case managers can provide guidance on insurance coverage and costs.
- Koselugo CoPay Program: For commercially insured patients, this program can reduce out-of-pocket expenses, with some eligible patients paying as little as $0.
- Community Support: The program also provides educational materials and connects families with advocacy groups and peer-to-peer support.
Nonprofit Support
Organizations like the PAN Foundation also offer financial assistance programs for patients with neurofibromatosis. These programs provide financial aid for out-of-pocket costs like deductibles, copays, and coinsurance, up to a certain annual limit. It is always recommended to check with such organizations for eligibility requirements and availability of funding.
How to Assess Your Potential Koselugo Costs
| Cost Factor | Description | Potential Out-of-Pocket Range (Per Month) |
|---|---|---|
| List Price | The official price set by the manufacturer, before any discounts, insurance coverage, or patient assistance. | ~$12,500 (average) |
| Commercial Insurance | Cost after meeting deductibles and paying copay or coinsurance, but before factoring in manufacturer assistance. | $0 to several thousand dollars |
| Commercial Insurance with CoPay Program | Cost for eligible commercially insured patients who enroll in the Alexion program. | As low as $0 |
| Medicare Part D | Cost during different coverage stages (deductible, initial, coverage gap, catastrophic), with specific rules for drug tiers. | Varies greatly, from $7 in catastrophic phase to several hundred dollars in initial stages |
| Medicaid / Government Plans | Cost determined by specific state regulations; not eligible for manufacturer copay assistance. | May be covered fully or require a low copay, depends on state |
| Uninsured | Full cost without insurance or assistance. | ~$12,500 or more |
The Path to Affordability
For a rare and expensive medication like Koselugo, finding ways to make treatment affordable is a multi-step process. Here are some key actions patients and caregivers can take:
- Engage Alexion OneSource™ early: The first and most important step is to contact Alexion's patient support program. Their case managers are trained to help navigate the financial landscape and enroll eligible patients in programs. This can drastically lower the final cost for commercially insured patients.
- Understand your insurance plan: Patients should thoroughly review their specific insurance policy, including formulary tiers, deductibles, and any prior authorization requirements for specialty medications. A call to the insurance provider's specialty pharmacy desk is often necessary.
- Explore nonprofit assistance: Check with foundations like the PAN Foundation for additional financial aid options. Their programs can often help cover remaining out-of-pocket costs not covered by other means.
- Compare pricing tools: Online resources like GoodRx or PharmacyChecker provide potential coupon prices, though these typically offer limited savings compared to dedicated patient assistance programs for highly specialized drugs like Koselugo.
Conclusion
While the sticker price of Koselugo is exceptionally high, the actual financial burden on a patient is significantly mitigated by insurance coverage and robust patient assistance programs. For families dealing with the complexities of NF1, the Alexion OneSource™ program is a critical resource for managing costs and ensuring access to this important medication. Taking proactive steps, including enrolling in support programs and understanding your specific insurance benefits, can make a life-changing difference in affording treatment.

Understanding How Koselugo is Priced
The price of any specialty drug like Koselugo is a complex issue driven by several market factors. As a rare disease treatment, Koselugo treats a very specific and small patient population. The high cost reflects the substantial investment in research, development, and clinical trials required to bring such a drug to market. This specialized development, coupled with a limited patient base, necessitates a pricing model that recoups research expenses and provides a return on investment for the manufacturer. Furthermore, the final price is often negotiated between the drug manufacturer and various healthcare payers (insurance companies, government programs), which determines the net price paid. For patients, navigating these complex pricing structures and financial obligations is where patient assistance programs become indispensable.
Koselugo's Place in NF1 Treatment Costs
Koselugo was a significant breakthrough as the first FDA-approved treatment for NF1-related plexiform neurofibromas. While previous treatments for NF1-related complications included surgery, pain medication, or chemotherapy, none directly targeted the underlying genetic pathway in the same way. The cost of Koselugo should be viewed in the broader context of NF1 management, which can include multiple types of care, including surgery, pain management, and other supportive treatments. Therefore, while Koselugo's price is high, its targeted efficacy potentially reduces other healthcare costs related to managing severe symptoms of NF1, such as repeat surgeries or emergency room visits. The emergence of targeted therapies like Koselugo represents a shift in NF1 care from symptom management to direct disease intervention.
Conclusion
Navigating the cost of Koselugo can be intimidating for families, but numerous support systems are in place to prevent the list price from becoming a patient's ultimate financial burden. The actual out-of-pocket expense is influenced by insurance, dosage, and eligibility for patient assistance. The Alexion OneSource™ program, in particular, offers vital resources, from copay assistance for commercially insured patients to general support for navigating the system. By actively exploring all available avenues of financial assistance, families can make this life-changing medication more accessible and manageable, ensuring the focus remains on the patient's health and well-being.
Navigating the Financial Labyrinth
For families facing a new Koselugo prescription, the journey from doctor's order to dispensed medication involves several logistical steps that impact cost. Typically, the prescribing physician's office will work with a specialty pharmacy, which specializes in handling high-cost, complex medications. The specialty pharmacy initiates the prior authorization process with the insurance company and can also coordinate with the Alexion OneSource™ program to determine eligibility for financial assistance. Patients should communicate closely with both the specialty pharmacy and the Alexion support team to track the process and understand all associated costs. Early and consistent communication is key to preventing delays in treatment and surprise expenses. While the healthcare system for specialty drugs is complex, a coordinated approach with your care team and support programs can help streamline access and affordability.
