Medicare Part D spending
CMS's Medicare Part D spending dataset reports gross spending on Simponi of $184.71 million in 2024, across 25,616 claims and 3,667 beneficiaries. CMS's dataset states spending is gross drug cost and does not reflect manufacturers' rebates or other price concessions.

FDA safety program (REMS)
- Simponi (application BLA125289): listed as released, without Elements to Assure Safe Use. Program dated April 24, 2009, last modified March 17, 2011. REMS@FDA program page.
A REMS is a safety program the FDA can require for a drug. Some restrict how it is prescribed or dispensed, for example through certified prescribers or pharmacies. This lists what the FDA's REMS@FDA files tie to the application; it does not say which prescribers or pharmacies take part, or whether a given patient needs the program.

Rare-disease (orphan) designations
The FDA's orphan drug database lists 4 designations for golimumab, 2 with an approval recorded. A designation is not an approval and not a statement that the drug treats the condition; the status column is the database's own.
| Designated | Designated use | Status | Sponsor |
|---|---|---|---|
| April 2, 2015 | Treatment of polyarticular juvenile idiopathic arthritis in patients 0 through 18 years of age. | Designated/Approved | Janssen Research & Development, LLC |
| May 21, 2012 | Treatment of sarcoidosis | Designated/Designation Withdrawn or Revoked | Janssen Biotech, Inc. |
| March 16, 2012 | Treatment of pediatric ulcerative colitis | Designated/Approved | Janssen Biotech, Inc. |
| November 2, 2004 | Treatment of chronic sarcoidosis | Designated/Designation Withdrawn or Revoked | Centocor, Inc. |

Medicaid use by state
CMS's State Drug Utilization Data records, for 2025, how many prescriptions each state's Medicaid program paid for under this drug's packages and what it reimbursed. The 2 states with the largest reimbursement are shown. Reimbursement is before the rebates manufacturers pay states, so it is not a net cost and not a price a patient pays.
| State | Medicaid-paid prescriptions | Medicaid reimbursed | Covers |
|---|---|---|---|
| KY | 140 | $626,462 | Fee-for-service only |
| ND | 59 | $364,006 | All record types |
Where the publisher suppresses small managed-care cells, a state's figure covers fee-for-service claims only and understates use (1 state and package figure is marked that way here). A state missing from the table means its figures were suppressed or not reported, not zero use. 39 older-year figures are held and left out of the table.

Medicaid spending
CMS's Medicaid spending dataset reports $62.11 million for Simponi in 2024. CMS's dataset states spending includes Federal and State reimbursement and dispensing fees and is not reduced by Medicaid rebates paid to the states. Spending is what Medicaid paid, not what a patient pays.
| Year | Spending | Claims |
|---|---|---|
| 2024 | $62.11 million | 9,712 |
| 2023 | $62.17 million | 10,049 |

Questions
Does Medicare have a negotiated price for Simponi?
The CMS negotiated-price file we read does not list Simponi, so this page shows no negotiated price. A drug appears in that file only when CMS selects it for negotiation, and not being listed says nothing about what it costs a patient.
Is there help paying for Simponi?
No program in our finder lists this drug yet.
