Out-of-province referral centre consults (e.g., from Winnipeg for patients in Northern Ontario) will also be considered on a case-by-case basis

Initial Criteria:

For the treatment of patients with pulmonary arterial hypertension (PAH) [WHO Group 1 Pulmonary hypertension] who meet all the following criteria:

  1. PAH defined as a resting mean pulmonary artery pressure (mPAP) of ≥ 25 mmHg at rest AND normal pulmonary capillary wedge pressure (PCWP) ≤ 15 mmHg on right heart catheterization1; AND 

  2. The drug request meets one of the following circumstances of use:
    a) Drug is being used as monotherapy in a patient with WHO-functional class III or IV;
    OR
    b)     Drug is being used as monotherapy in a patient with WHO-functional class II who has contraindication or has intolerance to a PDE-5 inhibitor;
    OR
    c)     Drug is being used as sequential dual therapy in combination with a funded PDE-5 (i.e., sildenafil, tadalafil) or a funded prostanoid (i.e., epoprostenol, treprostinil) in a patient who has had an inadequate response with monotherapy (i.e., failure to achieve WHO-FC I or II; or 6MWD >440 metres; or no/mild RV failure);
    OR
    d)     Drug is being used as up-front dual therapy in combination with a funded PDE-5 (i.e. sildenafil, tadalafil) or a funded prostanoid (i.e., epoprostenol, Treprostinil) in a patient with advanced disease (i.e., WHO-functional class III or IV; OR 6MWD less than 380 metres; OR evidence of RV failure.) 

1Note: Left ventricular end-diastolic pressure ≤15 mmHg is also acceptable.

For all funded PAH Drugs, case-by-case consideration may be provided for the following:

  • Requests for triple therapy (Including patients awaiting lung transplant.) 

  • Patients who may have mixed co-morbidities that include ILD, COPD or LV failure (i.e., patients with mixed WHO Group 1 and Group 3 pulmonary hypertension OR mixed WHO Group 1 and Group 2 pulmonary hypertension) 

Exclusion Criteria: 

Combinations of drugs targeting similar pathways will not be funded (i.e., combination regimen may only include one agent from each drug class -- phosphodiesterase type 5 [PDE-5] inhibitors, endothelin receptor antagonists (ERA), and/or prostanoids) 

Renewal criteria for funded PAH Drugs:

Renewals will be provided for patients who remain under the care of a physician from a recognized PAH Centre (see list above) and who continue to benefit from therapy. 

Approval Durations:
- Duration of Approval for Initial Requests: 1 year
- Duration on triple therapy regimens awaiting lung transplantation: 1 year
- Duration of first renewal: 1 Year
