Yervoy (ipilimumab) is one of the most expensive oncology drugs on the market, and the price you pay can vary a lot depending on how it’s dosed. Here’s a quick rundown of what you’re looking at in terms of cost‑difference per dosage:
| Dosing Regimen | Typical Cost per Infusion | Key Points |
|--------------------|------------------------------|----------------|
| 3 mg/kg IV (the “standard” weight‑based dose) | ≈ $10,000 – $12,000 per dose | The price scales with the patient’s weight. A 70‑kg patient gets 210 mg, which is roughly 70 % of the 300 mg “fixed” 10 mg dose. |
| 10 mg IV (fixed dose option that some insurers allow for patients < 75 kg) | ≈ $7,000 – $8,000 per dose | This is a lower cost option for lighter patients but is only used in specific payer or clinical scenarios. |
| 3 mg/kg + 10 mg (combination with nivolumab) | $10,000 + $5,000 (roughly $15,000‑$17,000 per infusion) | When Yervoy is paired with nivolumab (Opdivo), you pay for both drugs in the same infusion. |
How the “cost difference per dosage” breaks down
1. Weight‑based vs. fixed dose
* A 60‑kg patient receives 180 mg (3 mg/kg) → ≈ $10,000.
* The same patient could receive a 10 mg fixed dose → ≈ $7,500.
* Cost difference: ~ $2,500–$3,000 less per infusion for the fixed dose.
2. Across the weight spectrum
* A 100‑kg patient gets 300 mg (3 mg/kg) → ≈ $12,000.
* Fixed 10 mg dose is still ~ $7,500.
* Cost difference: ~ $4,500–$5,000 less per infusion for the fixed dose.
3. Combination therapy
* Yervoy + nivolumab: you pay for both drugs, so the difference is essentially the cost of the extra drug.
* If you compare Yervoy alone to the combination, the incremental cost is ~ $5,000–$6,000 per infusion.
Why the price is so high
* Manufacturing and development costs for monoclonal antibodies are extremely high.
* Patent protection keeps generic competition out of the market.
* High demand and limited supply (especially for specialty oncology pharmacies) allow manufacturers to charge premium prices.
Practical take‑aways
* Ask your pharmacy or insurer if they can use the 10 mg fixed dose for a lighter patient—it can cut the cost by ~ $3,000–$5,000 per infusion.
* Check for manufacturer copay assistance or patient support programs; they can sometimes lower the out‑of‑pocket amount.
* Compare total therapy costs (including other drugs in combination regimens) to understand the overall financial impact.

Bottom line:
Yervoy’s cost difference per dosage can range from about $2,500 to $5,000 less when you switch from the standard 3 mg/kg weight‑based dosing to the fixed 10 mg dose, depending on the patient’s weight. Combining Yervoy with other immunotherapies adds roughly $5,000–$6,000 per infusion, so the total financial impact can be significant. Always double‑check with your pharmacist or insurer, because pricing can fluctuate based on contracts, discounts, and regional variations.
