• INDICATIONS AND USAGE PIVYA is a penicillin class antibacterial indicated for the treatment of female patients 18 years of age and older with uncomplicated urinary tract infections (uUTI) caused by susceptible isolates of Escherichia coli, Proteus mirabilis and Staphylococcus saprophyticus . ( 1.1 ) To reduce the development of drug-resistant bacteria and maintain the effectiveness of PIVYA and other antibacterial drugs, PIVYA should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. ( 1.2 ) 1.1 Uncomplicated Urinary Tract Infections PIVYA is indicated for the treatment of female patients 18 years of age and older with uncomplicated urinary tract infections (uUTI) caused by susceptible isolates of Escherichia coli (E. coli) , Proteus mirabilis, and Staphylococcus saprophyticus. 1.2 Usage To reduce the development of drug-resistant bacteria and maintain the effectiveness of PIVYA and other antibacterial drugs, PIVYA 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.

• DOSAGE AND ADMINISTRATION The recommended dosage of PIVYA is one 185 mg tablet orally 3 times a day for 3 to 7 days as clinically indicated. ( 2.1 ) Administer PIVYA with or without food. ( 2.1 ) 2.1 Recommended Dosage The recommended dosage of PIVYA is one 185 mg tablet orally 3 times a day for 3 to 7 days as clinically indicated. Administer PIVYA with or without food [see Clinical Pharmacology ( 12.3 )] . PIVYA (pivmecillinam) is a prodrug of mecillinam (the active antibacterial agent) [see Clinical Pharmacology ( 12.3 )] . 2.2 Recommendations Regarding Missed Dose(s) If a dose of PIVYA is missed, instruct patients to take the dose as soon as possible. Do notdouble the dose to make up for the missed dose.

12.2 Pharmacodynamics Like other beta-lactam antibacterial drugs, the bacteriological effect of PIVYA in the treatment of uUTI is dependent on time above minimum inhibitory concentration (MIC), which has been shown to best correlate with efficacy in animal models of infection against E. coli .

• ADVERSE REACTIONS The following clinically significant adverse reactions are described in greater detail in the Warnings and Precautions section of labeling: Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] Severe Cutaneous Adverse Reactions [see Warnings and Precautions ( 5.2 )] Carnitine Depletion [see Warnings and Precautions ( 5.3 )] Acute Porphyria [see Warnings and Precautions ( 5.4 )] Clostridioides difficile -Associated Diarrhea [see Warnings and Precautions ( 5.5 )] The most common adverse reactions observed in ≥2% of the patients receiving PIVYA in clinical trials are nausea and diarrhea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Alembic Therapeutics at 1-866-210-9797 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 of PIVYA was evaluated in 579 adult female patients with uUTI who received PIVYA at a dose of 185 mg three times daily, or at higher daily doses (not approved for PIVYA) for 3 to 10 days in a placebo controlled trial (Trial 1, N=282), an active controlled trial (Trial 2, N=213) and an open label trial (Trial 3, N=84). The majority of patients were White women between 18 and 91 years of age. No serious adverse reactions were reported in patients treated with PIVYA in the trials. In Trial 1, the most common adverse reactions observed in ≥2% of the patients receiving PIVYA included nausea (4.3%) and diarrhea (2.1%). In Trial 2 and Trial 3, the most common adverse reaction occurring in ≥1% of patients receiving PIVYA was nausea with an incidence of 1.4% in Trial 2 and 3.6% in Trial 3. Table 1 lists the most frequently reported adverse reactions occurring in ≥1% of patients receiving PIVYA in Trial 1. Table 1…

• CONTRAINDICATIONS Serious hypersensitivity reactions (e.g., anaphylaxis or Stevens-Johnson syndrome) to PIVYA or to other beta-lactam antibacterial drugs (e.g., penicillins and cephalosporins). ( 4.1 ) Primary or secondary carnitine deficiency resulting from inherited disorders of mitochondrial fatty acid oxidation and carnitine metabolism, and other inborn errors of metabolism (e.g., methylmalonic aciduria, or propionic acidemia). ( 4.2 ) Acute porphyria. ( 4.3 ) 4.1 Serious Hypersensitivity Reactions PIVYA is contraindicated in patients who have experienced a serious hypersensitivity reaction (e.g., anaphylaxis or Stevens-Johnson syndrome) to PIVYA or other beta-lactam antibacterial drugs (e.g., penicillins and cephalosporins) [ see Warnings and Precautions ( 5.1 ) ]. 4.2 Carnitine Deficiency PIVYA is contraindicated in patients with primary or secondary carnitine deficiency resulting from inherited disorders of mitochondrial fatty acid oxidation and carnitine metabolism, and other inborn errors of metabolism (e.g., methylmalonic aciduria, or propionic acidemia) [ see Warnings and Precautions ( 5.3 ) ]. 4.3 Acute Porphyria PIVYA is contraindicated in patients suffering from porphyria as pivmecillinam has been associated with acute attacks of porphyria [see Warnings and Precautions ( 5.4 )] .

• WARNINGS AND PRECAUTIONS Hypersensitivity Reactions : Serious hypersensitivity reactions including anaphylaxis have been reported in patients treated with PIVYA. If hypersensitivity reactions occur, discontinue treatment with PIVYA and institute appropriate therapy. ( 5.1 ) Severe Cutaneous Adverse Reactions (SCAR) : Acute Generalized Exanthematous Pustulosis (AGEP), Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), Steven-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) have been reported with PIVYA. Monitor patients closely and discontinue PIVYA at the first signs or symptoms of SCAR or other signs of hypersensitivity. ( 5.2 ) Carnitine Depletion : Clinically significant hypocarnitinemia has been observed in patients at risk for reductions in serum carnitine. In patients with significant renal impairment or decreased muscle mass and those patients requiring long term antimicrobial treatment, consider alternative antibacterial therapies. PIVYA is not recommended when prolonged antibacterial treatment is necessary. Avoid concurrent treatment with valproic acid, valproate or other pivalate-generating drugs due to increased risk of carnitine depletion. ( 5.3 ) Clostridioides difficile -Associated Diarrhea (CDAD) : This has been reported for nearly all systemic antibacterial agents, including PIVYA. Evaluate if diarrhea occurs. ( 5.5 ) Interference with Newborn Screening Test : Treatment of a pregnant individual with PIVYA prior to delivery may cause a false positive test for isovaleric acidemia in the newborn as part of newborn screening. Prompt follow-up of a positive newborn screening result for isovaleric acidemia is recommended. ( 5.7 ) 5.1 Hypersensitivity Reactions Serious hypersensitivity reactions (anaphylaxis) have been reported in patients treated with PIVYA [see Adverse Reactions ( 6.1 )] . These reactions are more likely to occur in individuals with a history of penicillin, cephalosporin, or carbapenem hypersensitivity or a…

• DRUG INTERACTIONS 7.1 Other Pivalate-Generating Drugs Avoid concurrent treatment with valproic acid, valproate, or other pivalate-generating drugs. If concomitant use with PIVYA is necessary, counsel patients to monitor adverse reactions associated with carnitine depletion (e.g., hypoglycemia, muscle aches, fatigue, and confusion) [see Warnings and Precautions ( 5.3 )]. Pivmecillinam is a pivalate-generating prodrug [see Clinical Pharmacology ( 12.3 )] . Pivalate can be activated to a coenzyme-A thioester in cells which is further converted to pivaloylcarnitine and excreted in urine. Pivalate elimination associated with concomitant use of pivmecillinam with other pivalate-generating drugs decreases carnitine concentrations in plasma which may increase the risk of carnitine depletion-associated adverse reactions [see Warnings and Precautions ( 5.3 )] . 7.2 Methotrexate Clearance of methotrexate from the body can be reduced by concurrent use of drugs in the penicillin class, including PIVYA. Where possible, consider alternative therapy. 7.3 Drug Interference with Newborn Screening Test Treatment of a pregnant individual with PIVYA prior to delivery may cause a false positive test for isovaleric acidemia in the newborn as part of newborn screening. Prompt follow-up of a positive newborn screening result for isovaleric acidemia is recommended.
