Originator biologics (e.g., Enbrel®, Humira®, Remicade®, and Rituxan®) with a provincially funded biosimilar are only considered for provincial funding in patients who are treatment experienced and stable on the reference biologic or those with existing EAP approvals. Prescribers should refer to the ODB formulary for biosimilars and their funded conditions.

It should be noted that after the date when a biosimilar becomes publicly funded for an approved indication, patients initiated on a originator biologic for this same provincially funded indication through support from a manufacturer’s patient support program, may be expected to be provided ongoing access of the reference biologic through the patient support program or to use a biosimilar upon meeting specified criteria. The Ministry will only consider funding of Originator biologics with a funded biosimilar version in those who are treatment experienced and stabilized on the product prior to transitioning to the ODB program or in patients with an existing EAP approval.

Refer to the Executive Officer Communications on the Ministry website for Frequently asked questions and notifications of funded biosimilars at http://www.health.gov.on.ca/en/pro/programs/drugs/opdp_eo/eo_communiq.aspx

Effective March 31, 2023, the ODB program will start transitioning coverage for Copaxone®, Enbrel®, Humalog®, Humira®, Lantus®, NovoRapid®, Remicade®, and Rituxan® to their biosimilar versions.

Effective December 29, 2023, coverage for these originator biologic drugs through the ODB program will not be available for patients and the ODB program will only provide coverage for the biosimilar version of these drugs for all ODB program recipients, with limited exemptions (see below). In general, for ODB program recipients who are already on these biologic drugs, there is up to a 9-month transition period (see the biosimilar switch policy described on page 6 of this document)

For the treatment of polyarticular-course juvenile idiopathic arthritis in patients meeting the following criteria:

1. Patient has active disease (a minimum of 3 (three) swollen joints and a total of 5 active joints); AND

2. Patient has had an inadequate response to a three-month course of methotrexate administered subcutaneously at a dosage of at least 15 mg/m² per week for at least 3 months. If the patient is unable to tolerate or has a contraindication to subcutaneous methotrexate the nature of the intolerance or contraindication must be described in detail.; AND

3. Patient has had an inadequate response to a three-month course of etanercept OR adalimumab OR tociluzumab. If the patient is unable to tolerate or has a contraindication to etanercept OR adalimumab OR tociluzumab, the nature of the intolerance or contraindication must be described in detail.

Duration of Approval: 1 Year

Renewals will be considered for patients with objective evidence of at least a 20% reduction in swollen joint count. For renewals beyond the second year, objective evidence of preservation of treatment effect should be provided. (i.e., the current joint count should be compared to the count prior to initiating treatment with the biologic agent)

Duration of Approval: 5 Year

Approved Dose:

• Abatacept refer to the Orencia product monograph for dosing information

Note: If the patient cannot be treated with adequate trial(s) of methotrexate and/ or leflunomide due to contraindication(s) or intolerance(s), the nature of the contraindication(s) or intolerance(s) must be provided along with details of trials of other DMARDs or clear rationale why other DMARDs cannot be considered.
