In a double-blind, multiple-dose trial in 97 Type 2 diabetics on an isocaloric diet after stopping anti-hyperglycaemic medications for 2wk, canagliflozin 30, 100, 200, 400mg once-daily and 300mg bid x2wk showed 69, 76, 88, 113 and 88g mean 24hr urinary glucose excretion from day -1 to 16, respectively compared to -10g on placebo. The mean 24hr renal threshold for glucose excretion at day -1 and 16 were 259, 243, 247, 261 and 240mg/dl and 152, 116, 101, 90 and 90mg/dl on the 30, 100, 200, 400mg once-daily and 300mg bid doses compared to 241 and 232mg/dl on placebo, respectively. The mean 24hr plasma glucose at day -1 were 223, 212, 221, 242 and 206 mg/dl on the respective doses compared to 223mg/dl on placebo. The mean 24hr plasma glucose at day -1 to day 16 were -23, -47, -56.8, -64.2 and -55mg/dl on the doses compared to -18mg/dl on placebo. The fasting plasma glucose at day -1 were 199, 205, 208, 208 and 199mg/dl on the doses compared to 210mg/dl on placebo. The mean fasting plasma glucose at day -1 to day 16 were -20, -54, -65, -60 and -66mg/dl on the doses compared to -26mg/dl on placebo. Adverse events were transient, mild-to-moderate in intensity, and balanced across groups. One episode of vaginal candidiasis occurred in a canagliflozin treated subject. It reduced weight, was well tolerated and did not cause hypoglycaemia, consistent with the renal threshold with canagliflozin remaining above the hypoglycaemic threshold. Urine volume, electrolyte excretion, renal function, and lab safety values did not change meaningfully (69th Meet Am Diabetes Assoc (New Orleans), 2009, Abs 511-P; 70th Meet Am Diabetes Assoc (Orlando), 2010, Abs 568-P, http://professional.diabetes.org ... P=1&CID=79516). In a double-blind, placebo-controlled, dose-ranging trial in Type 2 diabetes with inadequate glycaemic control on metformin, canagliflozin 50, 100, 200, 300mg once-daily or 300mg bid x12wk was well tolerated and showed -16.2, -25.2, -32.4, -32.4 and -30.6mg/dl and -0.45, -0.51, -0.54, -0.71 and -0.73% change from baseline in fasting plasma glucose and A1C, with maximum and similar decreases observed at 300mg once-daily and bid doses compared to -18mg/dl and -0.56% on sitagliptin 100mg once-daily, respectively. Significant, dose-related weight reductions of -1.3, -1.5, -1.6, -2.3 and -2.3kg were observed across the canagliflozin arms but not with sitagliptin. Adverse events were transient, mild-to-moderate in intensity, and balanced across arms except for a non dose-dependent increase in symptomatic genital infections of 3-8% on canagliflozin arms, 2% on placebo and 2% on sitagliptin. 3-9% urinary tract infections were reported on canagliflozin arms, without dose-dependency compared to 6 and 2% on placebo and sitagliptin, respectively. 0-6% hypoglycaemia was reported on canagliflozin arms, without dose-dependency compared to 2 and 5% on placebo and sitagliptin, respectively. In canagliflozin arms, no safety signals in laboratory studies, ECG, or vital signs were observed (70th Meet Am Diabetes Assoc (Orlando), 2010, Abs 0077-OR, http://ww2.aievolution.com/ada10 ... Abs&abs=12778). It is in a randomized, double-blind, placebo-controlled, dose-ranging Phase II trial in 420 Type 2 diabetics aged 18-65yr, conducted by J&J, to evaluate the safety, efficacy and tolerability of canagliflozin 50, 100 and 500mg vs sitagliptin phosphate (ClinicalTrials.gov, 31 Mar 2008, http://clinicaltrials.gov/ct2/show/NCT00642278; Scrip Daily Online, 4 Nov 2008, S01012738). Diabetes, Type 2 Mitsubishi Tanabe Pharma A Japanese randomized, double-blind, placebo-controlled, parallel-group, dose-ranging Phase II (TA-7284-04) trial in 375 Type 2 diabetes patients, to evaluate TA-728 po on efficacy, safety, and tolerability was completed (ClinicalTrials.gov 2 Dec 2009 & 8 Jun 2011, http://clinicaltrials.gov/ct2/show/NCT01022112). An earlier Phase I/II trial in 60 Japanese patients with Type 2 diabetes was completed (ClinicalTrials.gov, 2 Jul 2009, http://clinicaltrials.gov/ct2/show/NCT00707954). Obesity Johnson & Johnson In a double-blind, ascending multiple-dose 14-day trial in 80 obese male and female subjects with a fixed weight-maintaining diet x15 days prior dosing and thought out the trial, canagliflozin 30, 100, 300, 600mg once-daily and 300mg bid showed 9, 33, 47, 50 and 61g increase in 24hr urinary glucose excretion on days 1-14, respectively compared to 0.1g on placebo. There were no meaningful changes in FPG, mean 24hr plasma glucose or insulin levels. -2.9, -2.7, -2.1, -3.4 and -3.5kg change in body weight were observed on 30, 100, 300, 600mg once-daily and 300mg bid doses, respectively compared to -1.4kg on placebo. There were no meaningful changes in self-reported appetite and satiety measures. The renal threshold (RT) for glucose excretion decreased in a dose-dependent manner with maximal effect on lowering of the RT to 64mg/dl. The 100mg dose provided near-maximal lowering of RT during the first 13hr post dosing. The 300mg bid and 600mg once-daily doses provided near-maximal lowering over the 24hr period. It was well tolerated, with no hypoglycaemia. Adverse events were transient and mild-to-moderate in severity. One woman in the 300mg bid arm experienced an asymptomatic urinary tract infection post-treatment. There were no clinically meaningful changes in urine volume or frequency, vital signs, ECGs, or laboratory tests (70th Meet Am Diabetes Assoc (Orlando), 2010, Abs 567-P, http://professional.diabetes.org ... P=1&CID=79515).

An open-label, fixed sequence Phase I trial (CR017815) in 18 healthy subjects, to assess the pharmacokinetic and pharmacodynamic interaction between single-dose metformin 1000mg tablet bid on day 1 and multiple-dose canagliflozin 300mg tablet once-daily on days 4-8 was completed (ClinicalTrials.gov, 12 Jan & 26 Feb 2011, http://clinicaltrials.gov/ct2/show/NCT01273571). An open-label drug interaction Phase I trial (CR017440) in 14 healthy male and female subjects, to assess the pharmacokinetics and pharmacodynamics of warfarin po 30mg on when administered alone and in combination with multiple-dose canagliflozin po 300mg tablet once-daily was completed (ClinicalTrials.gov, 2 Nov & 29 Dec 2010, http://clinicaltrials.gov/ct2/show/NCT01195324). It is in a US open-label Phase I trial (CR017227) in 24 subjects with various degrees of impaired hepatic function compared with subjects of normal hepatic function, to evaluate the pharmacokinetics of a single dose of canagliflozin po 300mg (ClinicalTrials.gov, 15 Oct 2010, http://clinicaltrials.gov/ct2/show/NCT01186588). A first-in-human Phase I trial in 71 healthy male subjects , to evaluate safety, tolerability, pharmacokinetics and pharmacodynamics of single-escalating canagliflozin po doses was completed (ClinicalTrials.gov, 13 Aug 2010, http://clinicaltrials.gov/ct2/show/NCT01177150). In a randomized, double-blind, double-dummy, placebo-and positive-controlled 4-way crossover study in 60 healthy adults, canagliflozin demonstrated that the change from baseline in QT interval corrected for heart rate ( QTcP) varied from -2.1ms 30min post dose to 0.5ms 3hr post dose on 300mg and -3.9ms 2hr post dose to -0.7ms 24hr post dose on 1200mg. The upper limits of the 2-sided 90% clearance for the difference in mean QTcP between canagliflozin and placebo were <10ms at each timepoint and for each canagliflozin dose, establishing noninferiority of the effect on QTc of both doses compared to placebo. The mean QTcP difference of moxifloxacin versus placebo was >10ms from 1-4hr post dose and assay sensitivity was established. At the mean maximum canagliflozin concentration, the predicted mean difference in QTcP between canagliflozin and placebo with 90% clearance was -1.3 on 300mg and -3.4 on 1200mg. It was generally well tolerated. No deaths, serious or severe adverse events or treatment-emergent hypoglycaemic episodes were reported (70th Meet Am Diabetes Assoc (Orlando), 2010, Abs 2177-PO, http://professional.diabetes.org ... P=1&CID=81073). In a double-blind, randomized, placebo-controlled, escalating-dose Phase I trial in 63 healthy adult men aged 37yr, canagliflozin liquid suspension 10, 30, 100, 200, 400, 600, 800mg once-daily or 400mg bid administered while fasting was well tolerated at all dose levels and significantly increased urinary glucose excretion in a dose-dependent fashion ranging from 5g at 10mg to a maximum mean 24hr urinary glucose excretion of 70g at doses >200mg. The renal threshold for glucose excretion decreased in a dose-dependent manner with maximal reduction to 61mg/dl. The 100 and 200 mg doses provided near-maximal suppression of renal threshold during the first 13hr after dosing, and doses >200mg provided near-maximal suppression over the 24hr period. Doses >200 mg also lowered the postprandial plasma glucose following breakfast. No hypoglycaemia was observed, and urine volume appeared not to be increased. Adverse events were transient and mild-to-moderate in intensity and were not dose-dependent. There were no clinically meaningful changes in laboratory safety tests, vital signs, or ECGs (70th Meet Am Diabetes Assoc (Orlando), 2010, Abs 0076-OR, http://ww2.aievolution.com/ada10 ... Abs&abs=12777). Diabetes, Type 2 Johnson & Johnson It is in a double-blind, placebo-controlled, randomized, parallel-group Phase I trial (CR100685; 28431754DIA1047; 2011-004117-17), to investigate the effects of canagliflozin on plasma volume and renal function in 40 subjects with Type 2 diabetes mellitus (ClinicalTrials.gov, 3 Dec 2011 & 24 Jan 2012, http://clinicaltrials.gov/ct2/show/NCT01483781). It is in an open-label, randomized, 2-way crossover, single-dose Phase I trial (TA-7284-07), to evaluate the pharmacokinetics, pharmacodynamics and safety of canagliflozin in 24 patients with Type 2 diabetes mellitus who have moderate renal impairment (ClinicalTrials.gov, 21 Jan 2012, http://clinicaltrials.gov/ct2/show/NCT01512849). A US randomized, double-blind, placebo-controlled, crossover Phase I trial (CR018373; 28431754DIA1045) in 36 Type 2 diabetes patients, to evaluate the effect of canagliflozin 300mg po capsule on post-meal glucose levels was completed (ClinicalTrials.gov, 16 Aug & 7 Dec 2011, http://clinicaltrials.gov/ct2/show/NCT01381887). An open-label Phase I trial (CR017719) in 28 Type 2 diabetics in Germany, to compare two methods for determining the renal threshold for glucose with canagliflozin 100mg po capsule once-daily x8 days was completed (ClinicalTrils.gov, 7 Feb & 15 Sep 2011, http://clinicaltrials.gov/ct2/show/NCT01273558). A randomized, double-blind, placebo-controlled, parallel-group Phase I trial (CR014881) in 29 Type 2 diabetes patients not optimally controlled on fixed doses of insulin therapy, to evaluate canagliflozin 100mg once-daily or 300mg bid capsule x4wk on safety, tolerability, pharmacokinetics and pharmacodynamics was completed (ClinicalTrials.gov, 13 Aug 2010, http://clinicaltrials.gov/ct2/show/NCT01177163). Results showed -0.73 and -0.92% A1C change from baseline on 100 and 300mg doses compared to -0.19% on placebo. -38.1 and -42.4mg/dl fasting plasma glucose (FPG) change from baseline was observed on the 100 and 300mg doses compared to 8.7mg/dl on placebo. 71.9 and 125.2g/day urinary glucose excretion (UGE) change from baseline was observed on the dose groups compared to -3.2g/day on placebo. -0.7 and -1.2kg body weight change from baseline was observed on the dose groups compared to 0 on placebo. A trend for blood pressure decrease was observed in canagliflozin-treated subjects. Canagliflozin AUC and Cmax increased with increasing dose and the mean t1/2 ranged from 12-15hr and was independent of dose. Plasma canagliflozin concentrations achieved steady-state within 7 days of dosing. No deaths or serious adverse events were observed. The incidence of treatment-emergent adverse events was similar across groups. There were no treatment-emergent adverse events related to urinary tract or genital infections. Overall, 12 subjects experienced > or =1 non severe hypoglycaemic episode. There were no severe hypoglycaemic events or discontinuations due to hypoglycaemia. There were no clinically meaningful changes in routine laboratory safety tests, vital signs, or ECGs (70th Meet Am Diabetes Assoc (Orlando), 2010, Abs 564-P, http://professional.diabetes.org ... P=1&CID=79512). A randomized, double-blind, placebo-controlled, parallel-group, multicenter Phase I trial in 39 patients with Type 2 diabetes, to assess canagliflozin 50, 100 and 300mg po once-daily x7 days on pharmacokinetic and pharmacodynamic characteristics was completed (ClinicalTrials.gov, 27 Jul 2010, http://clinicaltrials.gov/ct2/show/NCT01128985). Preclinical in vivo In diabetic mice and rats, and in obese dogs, it dose-dependently increased urinary glucose excretion, with a minimum effective dose (MED) of 0.3-1.0mg/kg (69th Meet Am Diabetes Assoc (New Orleans), 2009, Abs 534-P). In normal mice, Zucker diabetic fatty rats and obese dogs, single-dose canagliflozin po before an oral glucose chanllenge significantly increased urinary glucose excretion and urine volume, with a resulting significant decrease in blood glucose during oral glucose tolerance tests. In diabetic mice and rats, canagliflozin x4wk lowered fed and fasting blood glucose levels and HbA1c, with a MED of 0.3-1.0mg/kg. It also improved β-cell function as reflected in increased plasma insulin levels. There was no hyperglycaemia (69th Meet Am Diabetes Assoc (New Orleans), 2009, Abs 534-P). In a 4wk study in ob/ob mice, diet-induced obese mice or Zucker fatty rats, there was a signifcant reduction in body weight and decrease in food efficiency. It also resulted in a significant reduction in plasma free fatty acid levels and a significant decrease in respiratory exchange ratio and a marked increase of oxygen consumption (69th Meet Am Diabetes Assoc (New Orleans), 2009, Abs 534-P). It was well tolerated, without associated hypoglycaemia or weight gain and demonstrated potential for weight loss (Company presentation, J&J, 7 Jun 2007). It showed positive proof-of-concept. In a Type 2 diabetes rat model, canagliflozin administered at 7wk of age x32wk significantly decreased both blood glucose and haemoglobin levels and partially ameliorated oral glucose tolerance. Insulin resistance was reversed and there was a reduction of the thermal response in tail-flick testing following long-term hyperglycaemia. There was a significant prevention in the development of diabetic neuropathy (J Life Sci, 2005, 76, 2655). In vitro Further C-glucosides with a thiophene ring have been synthesized with increased stability (238th ACS (Washington, DC), 2009, MEDI 151). In cells overexpressing human SGLT2, it was 200x less potent on human SGL1 inhibition than on SGLT2, with an IC50 910nM. At 10μM, it did not interact with human SGLT3 or rat GLUT1 (69th Meet Am Diabetes Assoc (New Orleans), 2009, Abs 534-P).
