Chemical Structure

What Is Omadacycline Used For?

1 INDICATIONS AND USAGE NUZYRA is a tetracycline class antibacterial indicated for the treatment of adult patients with the following infections caused by susceptible microorganisms ( 1 ): Community-acquired bacterial pneumonia (CABP) ( 1.1 ) Acute bacterial skin and skin structure infections (ABSSSI) ( 1.2 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of NUZYRA and other antibacterial drugs, NUZYRA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. ( 1.3 ) 1.1 Community-Acquired Bacterial Pneumonia (CABP) NUZYRA is indicated for the treatment of adult patients with community-acquired bacterial pneumonia (CABP) caused by the following susceptible microorganisms: Streptococcus pneumoniae , Staphylococcus aureus (methicillin-susceptible isolates), Haemophilus influenzae , Haemophilus parainfluenzae , Klebsiella pneumoniae, Legionella pneumophila , Mycoplasma pneumoniae, and Chlamydophila pneumoniae . 1.2 Acute Bacterial Skin and Skin Structure Infections (ABSSSI) NUZYRA is indicated for the treatment of adult patients with acute bacterial skin and skin structure infections (ABSSSI) caused by the following susceptible microorganisms: Staphylococcus aureus (methicillin-susceptible and -resistant isolates), Staphylococcus lugdunensis , Streptococcus pyogenes, Streptococcus anginosus grp. (includes S. anginosus , S. intermedius , and S. constellatus ), Enterococcus faecalis , Enterobacter cloacae, and Klebsiella pneumoniae. 1.3 Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of NUZYRA and other antibacterial drugs, NUZYRA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described in greater detail in the Warnings and Precautions section of labeling: Mortality Imbalance in Patients with Community-Acquired Bacterial Pneumonia [see Warnings and Precautions (5.1) ] Tooth Development and Enamel Hypoplasia [see Warnings and Precautions (5.2) ] Inhibition of Bone Growth [see Warnings and Precautions (5.3) ] Hypersensitivity Reactions [see Warnings and Precautions (5.4) ] Tetracycline Class Effects [see Warnings and Precautions (5.6 )] The most common adverse reactions (incidence ≥2%) are nausea, vomiting, infusion site reactions, alanine aminotransferase increased, aspartate aminotransferase increased, gamma-glutamyl transferase increased, hypertension, headache, diarrhea, insomnia, and constipation. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Paratek Pharmaceuticals, Inc. at 1-833-727-2835 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. Overview of the Safety Evaluation of NUZYRA NUZYRA was evaluated in three Phase 3 clinical trials (Trial 1, Trial 2 and Trial 3). These trials included a single Phase 3 trial in CABP patients (Trial 1) and two Phase 3 trials in ABSSSI patients (Trial 2 and Trial 3). Across all Phase 3 trials, a total of 1073 patients were treated with NUZYRA (382 patients in Trial 1 and 691 in Trials 2 and 3 of which 368 patients were treated with only oral NUZYRA). Clinical Trial Experience in Patients with Community-Acquired Bacterial Pneumonia Trial 1 was a Phase 3 CABP trial that enrolled 774 adult patients, 386 randomized to NUZYRA (382 received at least one dose of NUZYRA and 4 patients did not receive the study drug) and 388 randomized to moxifloxacin (all 388 received at least one dose of moxifloxacin). The mean age of patients treated with NUZYRA was 61 years (range 19 to 97 years) and 42% were greater than or equal to 65 years of age. Overall, patients treated with NUZYRA were predominantly male (53.7%), white (92.4%), and had a mean body mass index (BMI) of 27.3 kg/m 2 . Approximately 47% of NUZYRA treated patients had CrCl <90 ml/min. Patients were administered an IV to oral switch dosage regimen of NUZYRA. The total treatment duration was 7 to 14 days. Mean duration of IV treatment was 5.7 days and mean total duration of treatment was 9.6 days in both treatment arms. Imbalance in Mortality In Trial 1, eight deaths (2%) occurred in 382 patients treated with NUZYRA as compared to four deaths (1%) in 388 patients treated with moxifloxacin. All deaths, in both treatment arms, occurred in patients >65 years of age. The causes of death varied and included worsening and/or complications of infection and underlying conditions. The cause of the mortality imbalance has not been established [see Warnings and Precautions (5.1) ] . Serious Adverse Reactions and Adverse Reactions Leading to Discontinuation In Trial 1, a total of 23/382 (6.0%) patients treated with NUZYRA and 26/388 (6.7%) patients treated with moxifloxacin experienced serious adverse reactions. Discontinuation of treatment due to any adverse reactions occurred in 21/382 (5.5%) patients treated with NUZYRA and 27/388 (7.0%) patients treated with moxifloxacin. Most Common Adverse Reactions Table 4 lists the most common adverse reactions occurring in ≥2% of patients receiving NUZYRA in Trial 1.

Drug Interactions

7 DRUG INTERACTIONS Patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage while taking NUZYRA. ( 7.1 ) Absorption of tetracyclines, including NUZYRA, is impaired by antacids containing aluminum, calcium, or magnesium, bismuth subsalicylate and iron containing preparations. ( 2.1 , 7.2 ) 7.1 Anticoagulant Drugs Because tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage while also taking NUZYRA. 7.2 Antacids and Iron Preparations Absorption of oral tetracyclines, including NUZYRA, is impaired by antacids containing aluminum, calcium, or magnesium, bismuth subsalicylate, and iron containing preparations [see Dosage and Administration (2.1) ].

Contraindications

4 CONTRAINDICATIONS NUZYRA is contraindicated in patients with known hypersensitivity to omadacycline or tetracycline class antibacterial drugs, or to any of the excipients [see Warnings and Precautions (5.3) and Adverse Reactions (6.1) ]. Known hypersensitivity to omadacycline, tetracycline class antibacterial drugs or any of the excipients in NUZYRA ( 4 )

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary NUZYRA, like other tetracycline class antibacterial drugs, may cause discoloration of deciduous teeth and reversible inhibition of bone growth when administered during the second and third trimester of pregnancy [see Warnings and Precautions (5.2 , 5.3) , Data , Use in Specific Populations (8.4) ]. The limited available data of NUZYRA use in pregnant women is insufficient to inform drug associated risk of major birth defects and miscarriages. Animal studies indicate that administration of omadacycline during the period of organogenesis resulted in fetal loss and/or congenital malformations in pregnant rats and rabbits at 7 times and 3 times the mean AUC exposure, respectively, of the clinical intravenous dose of 100 mg and the oral dose of 300 mg. Reductions in fetal weight occurred in rats at all administered doses (see Data ). In a fertility study, administration to rats during mating and early pregnancy resulted in embryo loss at 20 mg/kg/day; systemic exposure based on AUC was approximately equal to the clinical exposure level [see Nonclinical Toxicology (13.1) ] . Results of studies in rats with omadacycline have shown tooth discoloration. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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 15-20%. Data Animal Data Intravenous infusion of omadacycline to pregnant rats during organogenesis (gestation days 6-17) at doses of 5 to 80 mg/kg/day resulted in maternal lethality at 80 mg/kg/day. Increased embryo-fetal lethality and fetal malformations (whole body edema) occurred at 60 mg/kg/day (7 times the clinical AUC), dose-dependent reductions in fetal body weight occurred at all doses, and delayed skeletal ossification occurred at doses as low...

Overdosage

10 OVERDOSAGE No specific information is available on the treatment of overdosage with NUZYRA. Following a 100 mg single dose intravenous administration of omadacycline, 8.9% of dose is recovered in the dialysate.
