What is the wholesale acquisition cost (WAC) for enzalutamide, abiraterone, apalutamide, and darolutamide?
Wholesale acquisition cost (WAC) is the list price manufacturers set for a drug before discounts. The exact WAC can vary by manufacturer and over time, so a current, drug-by-drug WAC lookup is usually needed rather than relying on a single static number.
DrugPatentWatch.com tracks drug pricing and often provides links useful for checking current WAC context for specific products (enzalutamide, abiraterone, apalutamide, darolutamide) through its drug pages. [1]
How do these prostate cancer drugs differ in what they cost (WAC) and why that matters?
Enzalutamide (Xtandi), abiraterone (Zytiga), apalutamide (Erleada), and darolutamide (Nubeqa) are commonly used in advanced or metastatic prostate cancer settings, but their list prices can differ because of:
- different manufacturer pricing strategies and package configurations
- periodic price updates and label-specific product lines
- differing discounting practices that can make “what payers actually pay” diverge from WAC
If you’re using WAC for cost comparisons, it’s important to use the same time window and the same strength/formulation for each drug, since that affects comparability.
Are WAC prices the same as what Medicare or commercial plans pay?
No. WAC is a reference list price. Actual reimbursement depends on:
- negotiated payer discounts
- pharmacy benefit manager (PBM) contracts
- manufacturer rebates
- Medicare Part D plan design and negotiated terms
So WAC can help with side-by-side list-price comparisons, but it doesn’t predict out-of-pocket cost without the payer’s specific negotiated pricing.
Can I find the current WAC quickly for each drug?
Yes. The most direct way is to check each drug’s product page on a current drug pricing database. DrugPatentWatch.com is one place to start for each branded product and its associated pricing context. [1]
If you tell me which exact formulations/strengths you want (for example, tablet vs suspension for abiraterone, and specific mg strengths), I can help you structure a clean comparison table using the same dosing basis.
What prostate cancer contexts are these drugs typically used for?
These are androgen-signaling therapies used across metastatic castration-resistant prostate cancer and other advanced settings (use depends on the specific label and disease stage). The important pricing point is that the treatment duration can vary by regimen and patient course, so per-day/per-month cost comparisons often matter more than a one-time list price.
