1. INDICATIONS AND USAGE
GIAPREZA increases blood pressure in adults with septic or other distributive shock [see Clinical Studies (14)].
-
2. DOSAGE AND ADMINISTRATION
2.1. Preparation
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.
GIAPREZA must be administered as an intravenous infusion. GIAPREZA must be diluted in 0.9% sodium chloride prior to use. Dilute the appropriate amount of GIAPREZA in a normal saline (0.9% sodium chloride) infusion bag to achieve the desired final concentration of 5,000 ng/mL or 10,000 ng/mL.
Discard vial and any unused portion of the drug product after use.
Diluted solution may be stored at room temperature (20°C to 25°C [68°F to 77°F]) or under refrigeration (2°C to 8°C [36°F to 46°F]). Discard prepared solution after 24 hours at room temperature or under refrigeration.
2.2. Administration
The recommended starting dosage of GIAPREZA is 20 nanograms (ng)/kg/min via continuous intravenous infusion. Administration through a central venous line is recommended.
Monitor blood pressure response and titrate GIAPREZA as frequently as every 5 minutes by increments of up to 15 ng/kg/min as needed to achieve or maintain target blood pressure. Do not exceed 80 ng/kg/min during the first 3 hours of treatment. Maintenance dose should not exceed 40 ng/kg/min. Doses as low as 1.25 ng/kg/min may be used.
Once the underlying shock has sufficiently improved, down-titrate every 5 to 15 minutes by increments of up to 15 ng/kg/min based on blood pressure.

5. WARNINGS AND PRECAUTIONS
5.1 Risk for Thrombosis
The safety of GIAPREZA was evaluated in 321 adults with septic or other distributive shock in a randomized, double-blind, placebo-controlled study, ATHOS-3. There was a higher incidence of arterial and venous thrombotic and thromboembolic events in patients who received GIAPREZA compared to placebo-treated patients in the ATHOS-3 study (13% vs. 5%). The major imbalance was in deep venous thromboses. Use concurrent venous thromboembolism (VTE) prophylaxis.

6. ADVERSE REACTIONS
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.
ATHOS-3
The safety of GIAPREZA was evaluated in ATHOS-3 [see Warnings and Precautions(5.1)] . Patients in ATHOS-3 were receiving other vasopressors in addition to GIAPREZA or placebo, which were titrated to effect on mean arterial pressure (MAP).
Table 1 summarizes adverse reactions with an incidence of at least 4% among patients treated with GIAPREZA and with a rate of at least 1.5% higher with GIAPREZA than with placebo.

8. USE IN SPECIFIC POPULATIONS
8.1. Pregnancy
Risk Summary
The published data on angiotensin II use in pregnant women are not sufficient to determine a drug-associated risk of adverse developmental outcomes. Animal reproduction studies have not been conducted with GIAPREZA.
All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Clinical Considerations
Disease-associated maternal and/or embryo/fetal risk
Septic or other distributive shock is a medical emergency that can be fatal if left untreated. Delaying treatment in pregnant women with hypotension associated with septic or other distributive shock is likely to increase the risk of maternal and fetal morbidity and mortality.

11. DESCRIPTION
Angiotensin II is a naturally occurring peptide hormone of the renin-angiotensin-aldosterone system (RAAS) that causes vasoconstriction and an increase in blood pressure. GIAPREZA is a sterile, aqueous solution of synthetic human angiotensin II for intravenous administration by infusion. Each 2.5 mg/mL vial of GIAPREZA contains 2.5 mg angiotensin II equivalent to an average of 2.9 mg angiotensin II acetate, 25 mg mannitol, and Water for Injection adjusted with sodium hydroxide and/or hydrochloric acid to pH of 5.5. Each 0.5 mg/mL vial of GIAPREZA contains 0.5 mg angiotensin II equivalent to an average of 0.6 mg angiotensin II acetate, 25 mg mannitol, and Water for Injection adjusted with sodium hydroxide and/or hydrochloric acid to pH of 5.5.
The chemical name of the synthetic angiotensin II acetate is L-Aspartyl-L-arginyl-L-valyl-Ltyrosyl-L-isoleucyl-L-histidyl-L-prolyl-L-phenylalanine, acetate salt. The counter ion acetate is present in a non-stoichiometric ratio. It is a white to off-white powder, soluble in water.
The structure of angiotensin II acetate is shown below.
Molecular formula: C 50H 71N 13O 12 ∙ (C 2H 4O 2) n; (n= number of acetate molecules; theoretical n = 3)
Average molecular weight: 1046.2 (as free base).

12. CLINICAL PHARMACOLOGY
12.1. Mechanism of Action
Angiotensin II raises blood pressure by vasoconstriction and increased aldosterone release. Direct action of angiotensin II on the vessel wall is mediated by binding to the G-protein-coupled angiotensin II receptor type 1 on vascular smooth muscle cells, which stimulates Ca2+/calmodulin-dependent phosphorylation of myosin and causes smooth muscle contraction.
12.2. Pharmacodynamics
For the 114 (70%) patients in the GIAPREZA arm who reached the target MAP at Hour 3, the median time to reach the target MAP endpoint was approximately 5 minutes. GIAPREZA is titrated to effect for each individual patient.
12.3. Pharmacokinetics
Following intravenous infusion of angiotensin II in adults with septic or other distributive shock, serum levels of angiotensin II are similar at Baseline and Hour 3 after intravenous infusion. After 3 hours of treatment, however, the serum level of angiotensin I (the angiotensin II precursor peptide) is reduced by approximately 40%.
Metabolism and Excretion:
No specific studies were conducted that examined the metabolism and excretion of GIAPREZA.
The plasma half-life of IV administered angiotensin II is less than one minute. It is metabolized by aminopeptidase A and angiotensin converting enzyme 2 to angiotensin-(2-8) [angiotensin III] and angiotensin-(1-7), respectively in plasma, erythrocytes and many of the major organs (i.e., intestine, kidney, liver and lung). Angiotensin II type 1 receptor (AT1) mediated activity of angiotensin III is approximately 40% of angiotensin II; however, aldosterone synthesis activity is similar to angiotensin II. Angiotensin-(1-7) exerts the opposite effects of angiotensin II on AT1 receptors and causes vasodilation.
Specific Populations
No formal pharmacokinetic studies were conducted with GIAPREZA in the following specific populations.
Renal Impairment
The clearance of angiotensin II is not dependent on renal function. Therefore, the pharmacokinetics of GIAPREZA are not expected to be influenced by renal impairment.
Hepatic Impairment
The clearance of angiotensin II is not dependent on hepatic function. Therefore, the pharmacokinetics of GIAPREZA are not expected to be influenced by hepatic impairment.

13. NONCLINICAL TOXICOLOGY
13.1. Carcinogenesis, Mutagenesis, Impairment of Fertility
No genetic toxicity studies have been conducted with GIAPREZA. No carcinogenicity or fertility studies with GIAPREZA have been conducted in animals.
13.2. Animal Toxicology and/or Pharmacology
No animal toxicology studies were conducted with GIAPREZA.
13.3. Safety Pharmacology
In a cardiovascular safety pharmacology study in normotensive dogs, GIAPREZA doses of 150, 450, and 1,800 ng/kg (5, 15, and 60 ng/kg/min) were infused intravenously for 30 minutes each. At ≥ 450 ng/kg, GIAPREZA caused significantly elevated MAP and systemic vascular resistance, as expected. The 1,800 ng/kg dose also caused increased heart rate, increased systemic vascular resistance, increased left ventricular systolic and end-diastolic pressures, and PR interval prolongation. GIAPREZA did not significantly alter respiratory rate or cause electrocardiographic changes in QRS duration or QTc.

14. CLINICAL STUDIES
14.1. ATHOS-3
The Angiotensin II for the Treatment of High-Output Shock (ATHOS-3) trial was a double-blind study in which 321 adults with septic or other distributive shock who remained hypotensive despite fluid and vasopressor therapy were randomized 1:1 and treated with either GIAPREZA or placebo, both in addition to background vasopressor therapy. Doses of GIAPREZA or placebo were titrated to a target MAP of ≥ 75 mmHg during the first 3 hours of treatment while doses of other vasopressors were maintained. From Hour 3 to Hour 48, GIAPREZA or placebo were titrated to maintain MAP between 65 and 70 mmHg while reducing doses of other vasopressors. The primary endpoint was the percentage of subjects who achieved either a MAP ≥ 75 mmHg or a ≥ 10 mmHg increase in MAP without an increase in baseline vasopressor therapy at 3 hours.
91% of subjects had septic shock; the remaining subjects had other forms of distributive shock such as neurogenic shock. At the time of study drug administration, 97% of subjects were receiving norepinephrine, 67% vasopressin, 15% phenylephrine, 13% epinephrine, and 2% dopamine. 83% of subjects had received two or more vasopressors and 47% three or more vasopressors prior to study drug administration. 61% of subjects were male, 80% were White, 10% were Black, and 10% were other races. The median age of subjects was 64 years (range: 22-89 years). Patients requiring high doses of steroids, patients with a history of asthma or bronchospasm, and patients with Raynaud's syndrome were not included.
The primary endpoint was achieved by 70% of patients randomized to GIAPREZA compared to 23% of placebo patients; p < 0.0001 (a treatment effect of 47%). Figure 1 shows the results in all patients and in selected subgroups.

NE Equiv = norepinephrine equivalent dose: the sum of all vasopressor doses with each vasopressor dose converted to the clinically equivalent norepinephrine dose.
Note: The figure above presents effects in various subgroups, all of which are baseline characteristics. The 95% confidence limits that are shown do not take into account the number of comparisons made and may not reflect the effect of a particular factor after adjustment for all other factors. Apparent homogeneity or heterogeneity among groups should not be over-interpreted.
In the GIAPREZA-treated group, the median time to reach the target MAP endpoint was 5 minutes. The effect on MAP was sustained for at least the first three hours of treatment. The median dose of GIAPREZA was 10 ng/kg/min at 30 minutes. Of the 114 responders at Hour 3, only 2 (1.8%) received more than 80 ng/kg/min.
Patients were not necessarily on maximum doses of other vasopressors at the time of randomization. The effect of GIAPREZA when added to maximum doses of other vasopressors is unknown.
Mortality through Day 28 was 46% on GIAPREZA and 54% on placebo (hazard ratio 0.78; 95% confidence interval 0.57 – 1.07).
