Abstract Background Tebipenem pivoxil hydrobromide (TBP-PI-HBr) is an oral prodrug that is converted to tebipenem (TBP), the active moiety, with activity against multidrug-resistant gram-negative pathogens, including extended-spectrum-β-lactamase (ESBL)-producing Enterobacterales. TBP-PI-HBr is the first oral carbapenem intended for treating complicated urinary tract infections and acute pyelonephritis. This study evaluated the absorption, metabolism, and excretion (AME) of TBP-PI-HBr following a single oral dose of [14C]-TBP-PI-HBr to healthy males and characterized metabolites in plasma, urine, and feces. Methods This was a Phase 1, open-label, single-dose study in healthy subjects. Study drug was provided as radiolabeled and non-radiolabeled active pharmaceutical ingredient containing approximately 150 μCi of [14C]-TBP-PI-HBr. On Day 1, each subject received a 600 mg dose of TBP-PI-HBr. administered with 240 mL of water and fasted overnight for at least 10 hours. Blood samples were collected to determine TBP concentrations (whole blood), total radioactivity (whole blood and plasma), and metabolite profiling and identification were determined from plasma, urine, and feces. For mass balance, total radioactivity derived from urine and feces collections were determined. PK parameters were calculated using noncompartmental methods. Results Total radioactivity in plasma and whole blood decreased rapidly with geometric mean t½ values of 6.0 hours and 3.5 hours, respectively and Tmax of 1 hour. The cumulative mean recovery of radioactivity was 38.7% in urine and 44.6% in feces. Most of the administered radioactivity was recovered in the first 144 hours post dose in urine and feces (80.0%). Six of 8 subjects achieved a mass balance recovery ranging from 80.1% to 85.0%. The TBP plasma to total radioactivity ratio of 0.536 indicated that other metabolites contribute to the total radioactivity AUC in plasma. Metabolite profiling and identification results indicated that TBP was the major component in plasma and urine. The inactive ring open metabolite of TBP (LJC 11,562) was also found in plasma ( >10%), urine (5.27%), and feces ( >10%) as a secondary metabolite. Conclusion This study adequately characterized the AME of TBP-PI-HBr in humans. Disclosures Vipul K. Gupta, Ph.D., Spero Therapeutics (Employee, Shareholder) Gary Maier, PhD, Spero Therapeutics, Inc.

Abstract Background Tebipenem pivoxil hydrobromide (TBP-PI-HBr) is an oral prodrug that is converted to tebipenem (TBP), the active moiety being developed for treating complication urinary tract infections. Antacids and proton pump inhibitors are known to change gastric pH after administration, which could affect the absorption of oral medications. This study evaluated the effect of a single dose of aluminum hydroxide/magnesium hydroxide/simethicone and the effect of multiple doses of omeprazole on the PK of TBP, following a single dose of TBP-PI-HBr. Methods This was an open-label, 3-period, fixed sequence drug-drug interaction study. On Day 1, Period 1, subjects received a single oral dose of TBP-PI-HBr 600 mg (2 x 300 mg tablets) at Hour 0. On Day 1, Period 2, subjects received a single oral 20 mL dose of aluminum hydroxide 800 mg/magnesium hydroxide 800 mg/simethicone 80 mg suspension per 10 mL (Maalox® Advanced Maximum Strength oral suspension) with a single oral dose of TBP-PI-HBr 600 mg at Hour 0. In Period 3, on Days 1 through 5, subjects received a single oral dose of omeprazole 40 mg (Prilosec®) once daily (QD), at Hour -2. On Day 5, a single oral dose of 600 mg TBP-PI-HBr was administered at Hour 0. Whole blood sampling for TBP PK occurred pre-dose and up to 24 hours post dose. Whole blood samples were assayed for TBP by liquid chromatography-tandem mass spectrometry. Results Twenty subject were enrolled and completed the study. Geometric mean ratios for AUC indicated mean TBP exposure (AUC) was approximately 11% lower and mean Cmax was 22% lower for TBP-PI-HBr combined with aluminum hydroxide/magnesium hydroxide/simethicone vs. TBP-PI-HBr alone (Figure). Similarly, geometric mean ratios for AUC indicated mean TBP exposure (AUC) was approximately 11% lower and mean Cmax was 43% lower for TBP-PI-HBr in combination with omeprazole vs. TBP-PI-HBr alone. Because the PK/PD driver for TBP efficacy is AUC dependent, concomitant administration is not expected to impact the efficacy of oral TBP-PI-HBr. Figure 1. Arithmetic mean plasma TBP concentrations following a 600 mg dose of clinical study drug product (A1 and A2) and registrational drug product (B) – PK population. Conclusion Administration of TBP-PI-HBr combined with aluminum hydroxide/magnesium hydroxide/simethicone or omeprazole QD had no meaningful effect on plasma TBP exposure; Cmax decreased with both agents. Co-administration was generally safe and well tolerated. Disclosures Vipul K. Gupta, Ph.D., Spero Therapeutics (Employee, Shareholder) Gina Patel, PhD, Spero Therapeutics, Inc.

3566 Background: Brivanib alaninate (BMS-582664, B) is an oral prodrug of BMS-540215, a dual tyrosine kinase inhibitor of VEGFR and FGFR signaling pathways which are important for angiogenesis and tumor growth. The recommended phase II/III dose of B is 800 mg daily. Methods: A two-part, open-label, single-dose study was conducted in subjects with advanced or metastatic solid tumors. Part A represented the period for assessment of the pharmacokinetics (PK), metabolism, and elimination of B, In part A, subjects received a single oral dose of 800 mg [14C]-labeled B containing 100 μCi of total radioactivity (0.125 μCi/mg). Blood was collected at selected time points for analyses of PK, biotransformation, and total radioactivity over a 10-day period. Complete urinary and fecal output was collected over the 10-day period or until discharge, and analyzed for total radioactivity and biotransformation. Part B began when subjects completed Part A. Part B subjects received B administered orally at a dose of 800 mg once daily starting on approximately Day 15 to 17 of study. Subjects continued in this study until disease progression or unacceptable toxicity. Results: 4 subjects (2 NSCLC, 1 ovarian, 1 renal cell carcinoma) were treated with B in both parts A & B. B was tolerable with few G3/4 AEs (increased fatigue, 1 event, cognitive disturbance, 1 event). The results revealed that B is completely converted to active moiety, BMS-540215, after oral administration. BMS-540215 is extensively metabolized in humans. Elimination is primarily via the feces. Following a single oral dose of [14C]-labeled B, approximately 12% and 82% of the administered radioactivity was recovered in the urine and feces, respectively, within 10 days. BMS-540215 accounted for 0.00% and 7.4% of the administered dose in urine and feces, respectively, with the remainder of the dose being minor metabolites. The mean terminal t1/2 of BMS-540215 was 14 hours. Conclusions: After oral administration of single 800 mg oral doses of [14C] B, BMS-540215 was found to be the major active circulating moiety in plasma (22.5%). BMS-540215 is primarily eliminated via metabolism. [14C]-labeled B formulation was well tolerated with no AEs leading to the discontinuation of any subject. [Table: see text]

Randomized Crossover Study

ABSTRACT Twelve healthy volunteers participated in this randomized crossover study to compare the concentrations and recovery levels of fleroxacin and pefloxacin in urine and to assess their bactericidal activities against 12 strains of urinary pathogens with different susceptibilities over a wide range of MICs. The volunteers received a single oral dose of 400 mg of fleroxacin or 800 mg of pefloxacin. The mean cumulative renal excretion of unchanged fleroxacin,N-demethyl-fleroxacin, and N-oxide-fleroxacin accounted for 67, 7, and 6% of the total dose, respectively. The total urinary recovery of pefloxacin and the active metabolite norfloxacin was 34%. In the time-kill and the urinary bactericidal titer (UBT) studies, only the subjects’ urine not supplemented with broth was used. With most tested organisms and both quinolones it took more than 8 h to achieve a reduction in CFU of 99.9% (3 log units). Overall, there was a good correlation between UBTs and MICs for the strains. Against Escherichia coli ATCC 25922 the median UBTs were similar for both antibiotics and at least 1:8 for 96 h; against the E. coli strain for which the MIC was 0.5 μg/ml the UBT was at least 1:4 for 48 h. The UBTs of both drugs against Klebsiella pneumoniae were at least 1:16 for 72 h. The UBTs for Staphylococcus aureus (the MIC for which was 16 μg/ml) of both antibiotics were low, and in some of the samples, no bactericidal titers were observed. UBTs for Proteus mirabilis of pefloxacin are significantly higher than those of fleroxacin. For Pseudomonas aeruginosa the median UBTs were present for the 24-to-48-h interval. The same is true forEnterococcus faecalis. Against Staphylococcus saprophyticus, UBTs were present for at least 48 h with both quinolones. Overall, a single oral dose of 400 mg of fleroxacin exhibits UBTs comparable to those of 800 mg of pefloxacin. Therefore, it may be expected that half of the dose of fleroxacin gives comparable results in the treatment of urinary tract infections; this should be substantiated in comparative clinical trials.

Abstract Background Tofogliflozin is a highly selective sodium-glucose co-transporter 2 (SGLT2) inhibitor. A mass balance study with combinations of microdoses revealed that tofogliflozin has high oral bioavailability (97.5%) and that tofogliflozin in circulation is eliminated primarily by metabolic pathways, with the liver playing a prominent role in elimination. Objectives This study aimed to evaluate the effect of moderate hepatic impairment on the pharmacokinetics of tofogliflozin and on the pharmacodynamics (urinary glucose excretion [UGE]). Methods In an open-label, parallel-group study, 17 subjects (9 with moderate hepatic impairment [Child-Pugh Class B, score 7–9] and 8 healthy) received a single oral dose of 40 mg tofogliflozin. Plasma and urine concentrations of tofogliflozin were determined. Accumulated UGE, adverse events, and physiological and laboratory test data were monitored. Results Geometric mean ratio (GMR; geometric mean value for subjects with moderate hepatic impairment / geometric mean value for healthy subjects) of Cmax was 1.47 and GMR of AUCinf was 1.70. Moderate hepatic impairment had only a little effect on tmax and CLR but it prolonged MRT. The levels of cumulative UGE were similar between the 2 groups. No clinically significant adverse events, laboratory test values, or physiological test values were observed in any subject. Conclusions Moderate hepatic impairment increased Cmax and AUCinf of tofogliflozin by 47% and 70%, respectively. This increase in tofogliflozin exposure did not increase UGE in hepatically impaired subjects. A single oral dose of 40 mg tofogliflozin was well tolerated, supporting dose adjustment is unnecessary even in moderately hepatically impaired subjects.

ABSTRACT Absorption, metabolism, and excretion of [14C]viramidine, a prodrug of ribavirin, were studied in humans following a single oral dose (600 mg). Viramidine was rapidly absorbed, with a time to maximum concentration of the drug in plasma of 1.5 h. Viramidine and ribavirin accounted for only 4.3% and 42% of plasma area under the concentration-time curve (AUC) for radioactivity, respectively, indicating extensive conversion of viramidine to ribavirin, followed by further metabolism of ribavirin. The drug was largely trapped in red blood cells (RBC), with an RBC-to-plasma radioactivity AUC0-∞ ratio of 108. Excretion of total radioactivity in urine and feces accounted for 50.8% and 26.1% of the dose, respectively. The metabolic profile in urine (0 to 24 h) indicated that viramidine was excreted primarily as triazole carboxamide (TCONH2), triazole carboxylic acid nucleoside (TCOOH), and ribavirin with a small amount of unchanged viramidine, which each accounted for 64.1%, 17.0%, 15.7%, and 3.2% of urinary radioactivity, respectively. The amounts of unchanged viramidine (3.4% of dose) and ribavirin (10% of dose) in urine were small after oral administration of viramidine.

ABSTRACT Fosfomycin is widely used for the treatment of uncomplicated urinary tract infection (UTI), and it has recently been recommended that fosfomycin be used to treat infections caused by multidrug-resistant (MDR) Gram-negative bacilli. Whether urine acidification can improve bacterial susceptibility to fosfomycin oral dosing regimens has not been analyzed. The MIC of fosfomycin for 245 Gram-negative bacterial isolates, consisting of 158 Escherichia coli isolates and 87 Klebsiella isolates which were collected from patients with urinary tract infections, were determined at pH 6.0 and 7.0 using the agar dilution method. Monte Carlo simulation of the urinary fosfomycin area under the concentration-time curve (AUC) after a single oral dose of 3,000 mg fosfomycin and the MIC distribution were used to determine the probability of target attainment (PTA). Fosfomycin was effective against E. coli (MIC90 ≤ 16 μg/ml) but not against Klebsiella spp. (MIC90 > 512 μg/ml). Acidification of the environment increased the susceptibility of 71% of the bacterial isolates and resulted in a statistically significant decrease in bacterial survival. The use of a regimen consisting of a single oral dose of fosfomycin against an E. coli isolate with an MIC of ≤64 mg/liter was able to achieve a PTA of ≥90% for a target pharmacodynamic index (AUC/MIC) of 23 in urine; PTA was not achieved when the MIC was higher than 64 mg/liter. The cumulative fractions of the bacterial responses (CFR) were 99% and 55% against E. coli and Klebsiella spp., respectively, based on simulated drug exposure in urine with an acidic pH of 6.0. A decrease of the pH from 7.0 to 6.0 improved the PTA and CFR of the target pharmacodynamic index in both E. coli and Klebsiella isolates.

Abstract To quantitatively determine tricyclic antidepressant agents, we used a combined gas chromatograph/mass spectrometer system, and deuterium-labeled internal standards. Recovery exceeds 95% and the coefficient of variation is less than 4% for human whole-blood samples supplemented with 5 to 15 ng of clomipramine hydrochloride or 20 to 60 ng of dehydroimipramine hydrogen fumarate per milliliter. For both amines, the detection limit is 0.3 mug/liter; Six healthy volunteers who received a single oral dose of 50 mg of clomipramine hydrochloride showed peak drug concentrations in the blood 3 to 5 h after administration, ranging between 14.4 and 30.1 mug/liter. Plasma/whole blood concentration ratios varied from 0.70 to 1.20, and the cumulative renal elimination from 0 to 72 h is less than 0.2% of the dose. This method is suitable for in vivo bioavailability studies of unchanged clomipramine, dehydroimipramine, and imipramine after a single oral dose of as little as 25 mg.

Abstract Injected depot formulations of somatostatin peptide analogs are routinely used to treat acromegaly and neuroendocrine tumors (NETs). CRN00808, a small molecule nonpeptide selective somatostatin receptor 2 (sst2) agonist, is being evaluated for efficacy and safety in patients with acromegaly. The current Phase 1 study was conducted in two Parts: In Part A, the absorption, metabolism, excretion, and mass balance of a single oral dose of 20 mg [14C]-CRN00808 (3.0 MBq) oral solution was characterized in six healthy male subjects. Plasma, blood, urine, and feces were collected for up to 432 hours, and were analyzed for total radioactivity and CRN00808 concentrations (plasma only). Metabolite profiling was conducted on the plasma, urine, and feces samples. In Part B, the absolute bioavailability of CRN00808 was determined by administering a single oral dose of 20 mg CRN00808 compared with a single micro-tracer intravenous (IV) bolus injection of 50 µg [14C]-CRN00808 (0.0185 MBq) in five healthy male subjects. The IV dose was administered approximately 90 minutes after the oral dose. Plasma samples were collected for up to 144 hours and were analyzed for total radioactivity and CRN00808 concentrations (plasma only). Key data from Part A and Part B will be presented. Available data from Part A of the study show that >90% of radioactivity was recovered within 7 days of dosing. The primary route of excretion was the feces (>90%) with minimal excretion in the urine (<10%). Absorption of total [14C]-CRN00808-derived radioactivity in plasma was rapid (median Tmax=1 hour), and the mean Cmax, AUC0-∞, and t1/2 were determined to be 194 ng-equivalents/mL, 3340 ng-equivalents.hr/mL, and 31 hours, respectively. The pharmacokinetic parameters of unchanged CRN00808 in plasma were similar, suggesting that majority of the circulating drug-derived radioactivity is accounted for by unchanged CRN00808 and there are no abundant circulating metabolites. Treatment emergent adverse events associated with CRN00808 were generally mild and transient, and consistent with those reported with other somatostatin agonists. In conclusion, results from this clinical trial in healthy volunteers confirm that CRN00808 has excellent drug-like properties for chronic once-daily oral treatment of patients with acromegaly.
