Brief Summary:
DS-7309 is being developed for the treatment of type 2 diabetes mellitus (T2DM). This will be a randomized, placebo-controlled, blinded, sequential, multiple ascending dose study to assess the safety, tolerability, Pharmacokinetics (PK), and Pharmacodynamics (PD) of multiple doses of DS-7309 in subjects with T2DM.

Condition or disease Intervention/treatment Phase
Type 2 Diabetes Mellitus Drug: DS-7309 Drug: placebo Drug: Metformin Phase 1

Detailed Description:
DS-7309 is being developed for the treatment of type 2 diabetes mellitus (T2DM).

Primary Outcome Measures :
  1. safety and tolerability of DS-7309 [ Time Frame: 23 days, Day -7 through Day 16 ]

  2. To assess the effects of repeated doses of DS-7309 on blood pressure [ Time Frame: 23 days, Day -7 through Day 16 ]
    To assess the effects of repeated doses of DS-7309 on blood pressure (by means of 24 h ambulatory blood pressure measurements (ABPMs)

  3. To assess the effects of repeated doses of DS-7309 on lipid profile [ Time Frame: 23 days, Day -7 through Day 16 ]
    To assess the effects of repeated doses of DS-7309 on lipid profile (total, low-density lipoprotein (LDL), and high-density lipoprotein (HDL) cholesterol and triglycerides)

  4. To assess the effects of repeated doses of DS-7309 on plasma lactate levels [ Time Frame: 23 days; Day -7 through Day 16 ]
    To assess the effects of repeated doses of DS-7309 on plasma lactate levels

  5. To assess the effects of repeated doses of DS-7309 on C-peptide levels in T2DM subjects [ Time Frame: 23 days, Day -7 through Day 16 ]
    To assess the effects of repeated doses of DS-7309 on C-peptide levels in T2DM subjects

  6. To assess the effects of repeated doses of DS-7309 on glucagon levels in T2DM subjects [ Time Frame: 23 days, Day -7 through Day 16 ]
    To assess the effects of repeated doses of DS-7309 on glucagon levels in T2DM subjects

Ages Eligible for Study:   18 Years to 65 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male or female volunteers aged 18 to 65 years, inclusive.
  • Male subjects have to agree to contraception (condom with spermicide) in addition to having their female partner (if of child-bearing potential) use another form of contraception
  • Women must be of non-childbearing potential
  • Diagnosed with T2DM for at least 3 months prior to first dose.
  • Subjects must be either:

On monotherapy with either metformin or a DPP-IV inhibitor alone with a HbA1c between 6.5% to 9.5%, inclusive, and willing to discontinue current metformin or DPP-IV inhibitor treatment for at least 2 weeks prior to check in and until discharge from the clinic (for Cohorts A to E). OR Treatment naive from any anti-diabetes mellitus drugs for at least 3 months prior to Screening with an HbA1c between 7% to 10%, inclusive.
