How to Save Money on Ibalizumab in 2026: Coupons, Discounts, and Patient Assistance

How Much Does Ibalizumab Cost?

Ibalizumab (Trogarzo) is one of the most expensive HIV medications on the market. Without insurance or patient assistance, the cost can reach approximately $9,000 or more per month. The maintenance dose (800 mg every 2 weeks, or 4 vials/month) has been listed at approximately $3,659 per 2-vial carton, and a loading dose of 2,000 mg requires additional vials. The annual cost can exceed $100,000.

The good news: robust financial assistance programs exist for most patients. Very few people who are eligible for ibalizumab actually pay anywhere near the list price.

Option 1: Thera Patient Support Co-Pay Assistance (Commercially Insured)

If you have commercial (private) health insurance, the Thera Patient Support co-pay program is your most valuable resource. Eligible commercially insured patients may pay as little as $0 per injection when enrolled.

How to enroll: Call 1-833-23-THERA (1-833-238-4372) or visit trogarzo.com. A Thera Patient Care Coordinator will guide you through enrollment.

Note: Co-pay assistance programs are typically not available for patients on federally funded insurance programs like Medicare or Medicaid.

Option 2: AIDS Drug Assistance Programs (ADAP) — For Uninsured/Underinsured Patients

AIDS Drug Assistance Programs (ADAPs) are federally and state-funded programs that provide HIV medications—including ibalizumab—to people living with HIV who are uninsured, underinsured, or otherwise unable to afford their medications.

ADAP eligibility and formulary coverage vary by state. Thera Patient Support can help you determine if ibalizumab is covered by your state's ADAP and assist with enrollment. Alternatively, contact your state health department's HIV services program or a Ryan White case manager.

Option 3: Patient Assistance Program (PAP) — For the Uninsured

Theratechnologies offers a Patient Assistance Program (PAP) for patients who do not have insurance and do not qualify for or cannot obtain ADAP coverage. The PAP may provide ibalizumab at reduced or no cost based on financial need.

To apply: Contact Thera Patient Support at 1-833-238-4372. They will assess eligibility and guide you through the application process.

Option 4: Medicare Coverage — Part B for Infusion Drugs

Because ibalizumab is a provider-administered infusion, it is billed under Medicare Part B (not Part D). Under standard Medicare Part B, your cost share is up to 20% of the approved drug cost after you meet your Part B deductible ($257 in 2026). On a drug costing thousands of dollars per infusion, 20% can still be a significant expense.

Ways to reduce Medicare out-of-pocket costs:

Medicare Supplement (Medigap) plans: Can cover most or all of the Part B 20% coinsurance.

Qualified Medicare Beneficiary (QMB) program: Low-income beneficiaries may have Part B cost-sharing fully covered.

State ADAP programs: Some states use ADAP funds to pay Medicare Part B premiums and co-insurance for qualifying individuals.

Option 5: Medicaid — For Income-Eligible Patients

Medicaid covers ibalizumab in states that have included it in their formulary. Coverage and prior authorization criteria vary by state. In states that did not expand Medicaid under the ACA, some patients may fall through coverage gaps—ADAP is often the backstop in these situations.

Does GoodRx or Other Drug Discount Programs Work for Ibalizumab?

Standard drug discount programs like GoodRx or SingleCare are designed for retail pharmacy medications and are unlikely to apply to ibalizumab, which is dispensed exclusively through specialty pharmacies. For ibalizumab, the manufacturer's Thera Patient Support program, ADAP, and the Medicare/Medicaid pathways described above are the relevant assistance mechanisms.

Step-by-Step: Finding the Right Assistance for You

Call Thera Patient Support (1-833-238-4372). They can assess ALL assistance options available to you based on your insurance status and income.

If commercially insured: enroll in the co-pay assistance program—you may pay $0.

If on Medicare: explore Medigap supplemental coverage and QMB eligibility.

If uninsured or underinsured: apply for your state's ADAP program or the manufacturer PAP.
