yutrepia

For oral inhalation only. Do not swallow YUTREPIA capsules. Use only with the provided inhaler ( 2 ) • YUTREPIA should be administered 3 to 5 times per day. The contents of each capsule can be inhaled in 2 breaths. ( 2.1 ) • See Dosage and Administration for full instructions on dosing of patients who are treprostinil-naïve or transitioning from treprostinil inhalation solution to YUTREPIA ( 2.1 ) 2.1 Usual Dosage In Adults YUTREPIA capsules are for oral inhalation only and should be used only with the supplied inhaler. Do not swallow YUTREPIA capsules. YUTREPIA Dosing in treprostinil-naïve patients : In patients naïve to treprostinil, therapy should begin with 26.5 mcg 3 to 5 times per day, in 2 breaths based on patient response. Dosing in patients transitioning from treprostinil inhalation solution (Tyvaso) : Patients transitioning from treprostinil inhalation solution (Tyvaso), can begin YUTREPIA therapy 3 to 5 times per day, in 2 breaths, using the doses specified below ( Table 1 ): Table 1: YUTREPIA Dosing in Patients Transitioning from Treprostinil Inhalation Solution *Each breath of Tyvaso delivers approximately 6 mcg of treprostinil.

The following potential adverse reactions are described in Warnings and Precautions ( 5 ): - Decrease in systemic blood pressure [see Warnings and Precautions ( 5.1 )] . - Bleeding [see Warnings and Precautions ( 5.2 )] . Most common adverse reactions with YUTREPIA (³10%) are cough, headache, throat irritation, and dizziness. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Liquidia Technologies, Inc. at 1-888-393-LQDA (5732) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety and tolerability of YUTREPIA was evaluated in an open label study (INSPIRE) of 121 patients with PAH (WHO Group 1 and NYHA Functional Class II [80 patients] and Class III [41 patients]) followed for up to 2 months. The most commonly reported adverse reactions included cough, headache, throat irritation, dizziness, which are known side effects of treprostinil inhalation solution. Table 2 lists the adverse reactions that occurred at a rate of at least 4% of the overall INSPIRE safety population. The adverse reactions in the INSPIRE study were consistent with those observed in previous studies of inhaled…

In general, symptoms of overdose with treprostinil include flushing, headache, hypotension, nausea, vomiting, and diarrhea. Provide general supportive care until the symptoms of overdose have resolved.

7.1 Effect of Cytochrome P450 Inhibitors and Inducers In vitro studies of human hepatic microsomes showed that treprostinil does not inhibit cytochrome P450 (CYP) isoenzymes CYP1A2, CYP2A6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1 and CYP3A. Additionally, treprostinil does not induce cytochrome P450 isoenzymes CYP1A2, CYP2B6, CYP2C9, CYP2C19, and CYP3A. Human pharmacokinetic studies with an oral formulation of treprostinil (treprostinil diolamine) indicated that co-administration of the cytochrome P450 (CYP) 2C8 enzyme inhibitor gemfibrozil increases exposure (both C max and AUC) to treprostinil. Co-administration of the CYP2C8 enzyme inducer rifampin decreases exposure to treprostinil. It is unclear if the safety and efficacy of treprostinil by the inhalation route are altered by inhibitors or inducers of CYP2C8 [see Warnings and Precautions ( 5.3 )] . 7.2 Effect of Other Drugs on Treprostinil Drug interaction studies have been carried out with treprostinil (oral or subcutaneous) co-administered with acetaminophen (4 g/day), warfarin (25 mg/day), and fluconazole (200 mg/day), respectively, in healthy volunteers. These studies did not show a clinically significant effect on the pharmacokinetics of treprostinil. Treprostinil does not affect the pharmacokinetics or pharmacodynamics of warfarin. The pharmacokinetics of R- and S- warfarin and the INR in healthy subjects given a single 25 mg dose of warfarin were unaffected by continuous subcutaneous infusion of treprostinil at an infusion rate of 10 ng/kg/min.
