How much does durvalumab (Imfinzi) cost per month?
Durvalumab pricing depends heavily on the country, whether you’re paying out of pocket or through insurance, the exact dosing you receive (it’s weight-based or fixed dosing depending on regimen), and the number of vials used per infusion. Because of those variables, a single “cost per month” figure is hard to state accurately without your dosing regimen and location.

What dose schedule changes the monthly cost?
Durvalumab is typically given by infusion on a recurring cycle (commonly every 2 weeks in some settings and every 4 weeks in others, depending on the indication and protocol). Your monthly drug cost will change with:
- the dosing frequency (every 2 weeks vs. every 4 weeks),
- the prescribed dose per cycle, and
- vial strength and wastage (how many vials are needed to reach the dose).
Those factors directly affect how many vials are billed each month.
Does insurance vs. cash price change the “per month” number a lot?
Yes. The sticker price for durvalumab can be far higher than what patients actually pay with:
- commercial insurance (copay/coinsurance after formulary rules),
- Medicare/Medicaid coverage (if applicable), or
- patient assistance programs (when eligibility criteria are met).
So the “cost per month” patients report is often their out-of-pocket spend, not the wholesale acquisition cost.
Can you estimate durvalumab’s monthly cost if you tell me your regimen?
If you share:
1) your country,
2) the dose (mg) and infusion frequency (e.g., every 2 weeks or every 4 weeks), and
3) whether you want the wholesale/official price or your expected out-of-pocket cost,
I can help convert a listed per-infusion price into an estimated per-month cost for your schedule.
