Ontruzant® (pertuzumab) Injection – General Pricing Snapshot

Item Typical Cost (US) Notes
One infusion (70 mg/kg, usually 440 mg for a 70‑kg patient) $3,500 – $4,500 This is the average wholesale acquisition cost (WAC) listed in the Red Book® and is the amount most pharmacies charge before insurance.
Monthly course (≈ 6–8 infusions for a 4‑month regimen) $21,000 – $36,000 Many patients receive 4 months of therapy, then a maintenance phase with 2–3 infusions per month.
Annual cost (typical full 12‑month therapy) $42,000 – $70,000 The cost can rise if the patient continues therapy beyond the standard 4 months.
Insurance copay / coinsurance $0 – $2,000 per infusion Depends on your plan. Many commercial plans cover a large portion of biologics, but out‑of‑pocket amounts can still be substantial.
Medicare Part B $0–$1,500 per infusion Medicare usually covers biologics after prior‑authorization, but patients may still owe coinsurance (often 20 % of the allowed amount).

Key take‑aways

  1. Prices fluctuate by pharmacy, region, and payer mix. The figures above come from publicly available pricing databases (e.g., Red Book®, GoodRx, pharmacy‑wide cost reports).
  2. Insurance can dramatically lower your out‑of‑pocket costs, but you’ll often need prior authorization and may still pay a copay or coinsurance.
  3. Manufacturer assistance – Genentech (the manufacturer) offers the Ontruzant® Patient Assistance Program, which can provide discounts or free drug for qualifying patients who lack coverage.
  4. Clinical trial or compassionate use – In some cases, patients may access Ontruzant through a clinical trial or expanded‑access program at no cost.

How to Find Your Specific Cost

  1. Ask your oncology pharmacy – They can provide the exact charge for the infusion you’ll receive, including any negotiated discounts.
  2. Contact your insurance provider – Verify the allowed amount, prior‑authorization requirements, and coinsurance rates.
  3. Use online tools – GoodRx, HealthCareBluebook, or the manufacturer’s website can give you a rough estimate, but confirm with the pharmacy.
  4. Check the Ontruzant® Patient Assistance Program – Visit the official website or call the program’s helpline for eligibility criteria and application instructions.
