Inventor(s):	Michael Dunne, Tom LOUGHMAN, Aaron CAMERON
Assignee:	Iterum Therapeutics International Ltd
Application Number:	US16/972,300
Patent Claims:	1. A bilayer tablet, comprising: a first layer comprising about 500 mg of probenecid or a pharmaceutically acceptable salt thereof; a second layer comprising about 500 mg of: and from about 220 mg to about 230 mg of microcrystalline cellulose; from about 50 mg to about 60 mg of sodium croscarmellose; from about 3 mg to about 4 mg of intragranular magnesium stearate; from about 6 mg to about 8 mg of extragranular magnesium stearate; from about 65 mg to about 75 mg of lactose monohydrate; and from about 20 to about 23 mg of hydroxypropylcellulose. 2. A method of preparing the bilayer tablet of claim 1, comprising: i) compressing a first granular material comprising probenecid or a pharmaceutically acceptable salt thereof with a first force, thereby forming a pre-compressed first layer; ii) adding a second granular material comprising Compound III-2 to the pre-compressed first layer; and iii) compressing the pre-compressed first layer and the second granular material with a second force, thereby forming a pre-coated bilayer tablet. 3. A method of treating or preventing a disease, comprising administering to a subject in need thereof a pharmaceutically effective amount of the bilayer tablet of claim 1. 4. The method of claim 3, wherein the subject in need thereof is a human. 5. The method of claim 3, wherein the disease comprises an increased or decreased population of one or more bacteria selected from Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Enterobacter cloacae, Klebsiella oxytoca, Citrobacter freundii complex, Clostridium clostridioforme, Eubacterium lentum, Peptostreptococcus species, Bacteroides fragilis, Bacteroides distasonis, Bacteroides ovatus, Bacteroides thetaiotaomicron, Bacteroides uniformis, Porphyromonas asaccharolytica, Prevotella bivia, Staphylococcus epidermidis, Streptococcus pneumonia, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus pyogenes, Citrobacter freundii, Citrobacter koseri, Enterobacter aerogenes, Enterobacter cloacae, Haemophilus influenza, Haemophilus parainfluenzae, Klebsiella oxytoca, Moraxella catarrhalis, Morganella morganii, Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Serratia marcescens Bacteroides vulgatus, Clostridium perfringens, and Fusobacterium spp. 6. The method of claim 3, wherein the disease is an infection selected from an uncomplicated urinary tract infection, a complicated urinary tract infection, a complicated intra-abdominal infection, pneumonia, otitis media, sinusitis, gonococcal urethritis, pelvic inflammatory disease, prostatitis, bone infection, joint infection, diabetic foot infection, and infectious diarrhea. 7. The method of claim 3, wherein the disease is a neurodegenerative disease, amyotrophic lateral sclerosis, Parkinson's disease, Alzheimer's disease, or Huntington's disease, cancer, or an inflammatory bowel disease. 8. The method of claim 3, wherein the bilayer tablet is administered to the subject with food. 9. The method of claim 3, wherein the administration results in a plasma concentration for the β-lactam compound having an area under the curve (AUC) that is higher in the subject in need thereof as compared to a comparable subject being administered with a comparable composition. 10. The method of claim 3, wherein the administration results in a maximum plasma concentration (Cmax) in the subject in need thereof that substantially the same as compared to a comparable subject being administered with a comparable composition.
