FDA approves Pivya (pivmecillinam) tablets for the treatment of female adults with uncomplicated urinary tract infections – Utility Therapeutics

Utility Therapeutics received approval from the FDA for Pivya (pivmecillinam) tablets for the treatment of female adults with uncomplicated urinary tract infections (UTIs) caused by susceptible isolates of Escherichia coli, Proteus mirabilis and Staphylococcus saprophyticus. Uncomplicated UTIs are bacterial infections of the bladder in females with no structural abnormalities of their urinary tract.

Pivya’s efficacy in treating females 18 years of age or older with uncomplicated UTIs was assessed in three controlled clinical trials comparing different Pivya dosing regimens to placebo, to another oral antibacterial drug and to ibuprofen. The primary measure of efficacy for the three trials was the composite response rate, which included clinical cure and microbiological response.

The composite response rate was assessed approximately 8 to 14 days after patients were enrolled into the studies. In the clinical trial comparing Pivya to placebo, 62% of the 137 subjects who received Pivya achieved the composite response compared to 10% of the 134 who received placebo. In the clinical trial comparing Pivya to another oral antibacterial drug, 72% of the 127 subjects who received Pivya achieved composite response compared to 76% of the 132 who received the comparator drug. In the clinical trial comparing Pivya to ibuprofen, 66% of the 105 subjects who received Pivya achieved composite response compared to 22% of the 119 who received ibuprofen.
