What is Aurlumyn?

From the FDA label:AURLUMYN contains iloprost, a synthetic analog of prostacyclin PGI 2 . The chemical name for iloprost is (5 E )-[3a S ,4 R ,5 R ,6a S )-5-hydroxy-4-[(1 E )-(3 S ,4 RS )-3-hydroxy-4-methyloct-1-en-6-ynyl]-hexahydropentalen-2(1 H )-ylidene]pentanoic acid. Iloprost consists of a mixture of the 4R and 4S diastereoisomers at a ratio of approximately 53:47. Iloprost is an oily substance, which is soluble in methanol, ethanol, ethyl acetate, acetone, and pH 7 buffer, sparingly soluble in buffer pH 9, and very slightly soluble in distilled water, buffer pH 3, and buffer pH 5. The molecular formula of iloprost is C 22 H 32 O 4 and its molecular weight is 360.49. The structural formula is shown below: AURLUMYN (iloprost) injection is a clear, colorless, sterile solution formulated for intravenous use. AURLUMYN is supplied in single-use glass vials containing 1-mL per vial. Each mL of the solution contains 100 mcg (0.1 mg) of iloprost as the active ingredient and the following inactive ingredients: 8.1 mg ethanol, 9 mg sodium chloride, and 0.242 mg tromethamine. Hydrochloric acid and sodium hydroxide is added to adjust pH to 8.3. The solution contains no preservatives. Chemical Structure

How to use

Initiate intravenous infusion at 0.5 ng/kg/minute and titrate in 0.5 ng/kg/minute increments based on tolerability at intervals of 30 minutes to a maximum of 2 ng/kg/minute ( 2.1 ). Administer as continuous infusion for 6 hours each day up to a maximum of 8 consecutive days ( 2.1 ). Patients with moderate or severe hepatic impairment (Child-Pugh Class B or C): initiate infusion at 0.25 ng/kg/minute and titrate as described above ( 2.3 ). Patients with renal impairment with eGFR less than 30 mL/min: initiate infusion at 0.5 ng/kg/minute and titrate as described above. If the patient cannot tolerate the starting dose of 0.5 ng/kg/minute, the dose can be decreased to 0.25 ng/kg/minute ( 2.4 ). See Full Prescribing Information for instructions on preparation and administration ( 2.2 ). 2.1 Recommended Dosage Monitor vital signs prior to the start of the infusion and with every dose increase. Administer AURLUMYN as a continuous intravenous infusion over 6 hours each day for up to a maximum of 8 consecutive days. Start the initial infusion on day 1 at a rate of 0.5 ng/kg/minute and increase in increments of 0.5 ng/kg/minute every 30 minutes according to tolerability up to 2 ng/kg/minute. Dosage is based on actual patient body weight (kg). Repeat dose titration steps on day 2 and day 3. From day 4 onward, start the infusion at the highest tolerated dose from the previous day, and…

Side effects

Most common adverse events include headache, flushing, palpitations/tachycardia, nausea, vomiting, dizziness, and hypotension (6.1). To report SUSPECTED ADVERSE REACTIONS, contact BTG International, Inc. at 1-877-377-3748 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Studies 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. Adverse events reported with the use of intravenous iloprost in patients with frostbite from the published literature include headache, flushing, palpitations/tachycardia, nausea, vomiting, dizziness, and hypotension. Pre-marketing safety data on AURLUMYN were obtained from 116 patients with Systemic Sclerosis receiving iloprost in 2 multicenter, double-blind, randomized, placebo-controlled studies in patients with Systemic Sclerosis experiencing symptomatic digital ischemic episodes (Raynaud's Phenomenon). Patients received intravenous AURLUMYN administered as a continuous infusion over 6 hours each day for 5 consecutive days and the dose was adjusted according to individual tolerability within the range of 0.5 to 2.0 ng /kg /min. The observed safety profile in these patients was similar to that observed with IV…

Warnings

Important safety information

AURLUMYN may cause symptomatic hypotension. Monitor vital signs while initiating AURLUMYN. Correct hypotension prior to administration of AURLUMYN ( 5.1 ). 5.1 Hypotension AURLUMYN is a systemic vasodilator and may cause symptomatic hypotension. Correct hypotension prior to administration of AURLUMYN. Monitor vital signs while administering AURLUMYN. Consider temporary discontinuation of concomitant vasodilator or other antihypertensive medications while administering AURLUMYN to reduce potential additive hypotensive effects. Consider down-titration or discontinuation of AURLUMYN if hypotension persists despite discontinuation of other antihypertensives and fluid resuscitation.
