Official Title: A Phase I, Randomized, Double-Blind, Placebo-Controlled, Crossover Study to Determine the Safety, Tolerability, Pharmacokinetics, Food Effect and Pharmacodynamics of Single and Multiple Ascending Doses of P7435 in Healthy, Overweight or Obese Subjects.
Study Start Date : August 2013
Actual Primary Completion Date : November 2014
Actual Study Completion Date : November 2014

Arm Intervention/treatment
Experimental: P7435
  • In Part A, there will be up to 6 cohorts of 8 subjects each (for the 2 cohorts undergoing food effect study, there will be 12 subjects in each cohort). At each dose level, every subject will participate in two periods (one with active, P7435 and the second period with matching placebo or vice versa) separated by appropriate wash-out period between the two periods. The randomization scheme will ensure that no subject undergoes the placebo period twice.
  • In Part B, there will be up to 3 cohorts of 10 subjects each. Each of the 3 cohorts will participate in two study periods of 10 days of dosing in each (one period with active, P7435 and the other period with matching placebo or vice versa) separated by appropriate wash-out period.
Drug: P7435
Placebo Comparator: Placebo

Primary Outcome Measures :
  1. Number of participants with adverse events (single and multiple dose studies) [ Time Frame: 12-14 Months ]
    - To determine the safety and tolerability of single (Part A) and multiple (Part B) ascending doses of P7435 in healthy, overweight or obese subjects


Secondary Outcome Measures :
  1. Food Effect [ Time Frame: 12-14 Months ]
    • To determine the effect of food on the pharmacokinetics (PK) of P7435 following single oral doses in these subjects (Part A)
    • The pharmacokinetic parameters (but not limited to) calculated in the double-blind active period (fed) versus the open-label active period (fasted) will be considered for the determination of the food effect.
    • The following parameters will be calculated: Cmax, tmax, tlag, AUC0-t, AUC0-inf, %AUC extrapolated, AUC0-24, kel, t½ for each of the periods i.e., fasted versus fed.

  2. Area under the plasma concentration (AUC) [ Time Frame: 12- 14 Months ]

    Part A: The PK profile will be derived from the P7435 plasma concentration data on Day 1.

    Part B: The PK profile will be derived from the P7435 plasma concentration data on Days 1 and 10. Trough levels will be compared to assess steady state.


  3. Peak Plasma concentration (Cmax) [ Time Frame: 12- 14 Months ]

    Part A: The PK profile will be derived from the P7435 plasma concentration data on Day 1.

    Part B: The PK profile will be derived from the P7435 plasma concentration data on Days 1 and 10. Trough levels will be compared to assess steady state.


  4. Time to peak plasma concentration (t-max) [ Time Frame: 12- 14 Months ]

    Part A: The PK profile will be derived from the P7435 plasma concentration data on Day 1.

    Part B: The PK profile will be derived from the P7435 plasma concentration data on Days 1 and 10. Trough levels will be compared to assess steady state.


  5. Change in Fasting serum lipids [ Time Frame: 12- 14 Month ]
    - Fasting serum lipids [total cholesterol, triglycerides, low-density lipoproteins (LDL C), high-density lipoproteins (HDL-C), very-low-density lipoproteins (VLDL), free fatty acids and apolipoprotein-B (Apo-B)] (Part B only)

  6. Change in Fasting plasma glucose [ Time Frame: 12- 14 Months ]
    Part B only

  7. Fat tolerance test [ Time Frame: 12- 14 month ]
    - Fat tolerance test variables including peak and post-prandial glucose, insulin, C peptide, lipids, GLP-1 and GIP and inflammatory biomarkers such as malondialdehyde and β-hydroxy butyrate (Part A and B)

  8. Fasting serum insulin [ Time Frame: 12 - 14 months ]
    Part B only

  9. Fasting serum C-peptide [ Time Frame: 12-14 months ]
    Part B only
