TREPROSTINIL CAP,INHL
Clinical Criteria Summary
Document 543
Provider & Care Setting Requirements
- Care provided by a VA or VA Community Care provider experienced in the management of PAH
Diagnostic & Hemodynamic Criteria
- Definitive PAH confirmed by right-heart catheterization and hemodynamic diagnosis
- Mean pulmonary artery pressure greater than 20 mmHg
- Pulmonary capillary wedge pressure 15 mmHg or less
- Pulmonary vascular resistance greater than 2 Wood units
Classification & Clinical Status
- World Health Organization (WHO) Group 1 PAH
- Unacceptable or deteriorating clinical status on PAH-directed therapy with, or not a candidate for, an endothelin receptor antagonist (ERA) and phosphodiesterase-5 inhibitor (PDE5i)
- Efficacy established in patients with NYHA Functional Class III symptoms
Formulation & Dosing Preferences
- Nebulized solution preferred if patient requires more than one cartridge or capsule per dose using the DPI (e.g., >64 mcg of TYVASO or >106 mcg of YUTREPIA)
- Dry powder inhalers (DPIs) reserved for patients with documented inability to use the nebulized product
Adjudication & Documentation
- Individual cases that are exceptions to inclusion/exclusion criteria should be adjudicated at the local facility level per P&T committee and pharmacy services policy/procedures
- Product information should be consulted for detailed prescribing information
Document 544
Provider & Care Setting Requirements
- Care must be provided by a VA or VA Community Care provider experienced in the management of pulmonary hypertension (PH).
Diagnosis & Indication Criteria
- Definitive, confirmed diagnosis of interstitial lung disease (ILD) (e.g., diffuse parenchymal lung disease on chest CT).
- Examples of ILD include idiopathic interstitial pneumonia, combined pulmonary fibrosis and emphysema, connective tissue disease, and chronic hypersensitivity pneumonitis.
- Definitive, confirmed diagnosis of WHO Group 3 PH associated with ILD.
Hemodynamic Criteria (via Right-Heart Catheterization)
- Mean pulmonary artery pressure of at least 25 mmHg.
- Pulmonary capillary wedge pressure of 15 mmHg or less.
- Pulmonary vascular resistance greater than 3 Wood units.
Formulation & Dosing Preferences
- Nebulized solution is preferred for patients requiring more than one cartridge per dose using the dry powder inhaler (DPI) (e.g., >64 mcg of TYVASO or >106 mcg of YUTREPIA).
- DPI should be reserved for patients with a documented inability to use the nebulized product.
Adjudication & Clinical Management
- All inclusion criteria must be met.
- Individual cases that are exceptions to exclusion/inclusion criteria or require formulation preference adjustments should be adjudicated at the local facility level per P&T Committee and Pharmacy Services policies/procedures.
Document 779
Indications
- Pulmonary arterial hypertension (PAH) (WHO Group 1) to improve exercise ability
- Pulmonary hypertension associated with interstitial lung disease (PH-ILD; WHO Group 3) to improve exercise ability
Patient Population & Eligibility
- WHO Group 1 PAH patients who are either prostacyclin naïve and on ≤2 nonprostacyclin oral PAH agents, or transitioning from stable doses of nebulized treprostinil
- Patients with PH-ILD (not specifically evaluated in clinical trials but considered for use)
- May be useful for patients who are unable to use DPIs that require strong inhalation due to low inspiratory effort requirement
Dosing Requirements
- Treatment naïve: Initiate at 26.5 mcg four times daily
- Target maintenance dose: 79.5 to 106 mcg four times daily
- Transitioning from treprostinil nebulized inhalation solution (TYVASO): Dose determined by current TYVASO breaths per dose (≤5 breaths = 26.5 mcg; 6–8 breaths = 53 mcg; 9–11 breaths = 79.5 mcg; 12–14 breaths = 106 mcg; 15–17 breaths = 132.5 mcg requiring 2 capsules; ≥18 breaths = 159 mcg requiring 2+ capsules)
- Doses exceeding 106 mcg require two capsules and double the cost
Safety & Monitoring Considerations
- Monitor for common adverse events: cough, headache, throat irritation, dizziness
- Discontinuation due to adverse events observed at 12% in clinical trials
- Assess risk of symptomatic hypotension (vasodilator effect)
- Assess risk of bleeding (platelet aggregation inhibitor)
- Monitor for bronchospasm, with increased risk in patients with asthma, COPD, or other bronchial hyperreactivity
- Adjust/monitor for CYP2C8 inhibitor co-administration (increased exposure) and CYP2C8 inducer co-administration (decreased exposure)
Formulary & Use Context
- Considered an alternative to treprostinil inhaled nebulized solution (TYVASO) or TYVASO DPI for PAH and PH-ILD
- Approved based on demonstration of safety and tolerability rather than efficacy
- Requires administration via a specialized capsule-based inhaler; device discarded every 7 days
