NCT00729365

Brief Summary

The purpose of this study is to determine if the early treatment with a blood pressure medication (an ACE Inhibitor) can prevent or delay the development of kidney disease (microalbuminuria) in patients with Type 1 diabetes who have normal blood pressure and urine albumin levels.

Outcome Measures

Primary Outcomes (1)

  • Development of Microalbuminuria (High Urine Albumin). Hypertension, Urine and Blood Markers Will Also be Evaluated for Assessment of Kidney Disease State.

    at 3months and then every 6months during the 5years of the study

Secondary Outcomes (1)

  • We Will Assess Changes in the Relative Stiffness of Your Arteries (Endothelial Dysfunction) in Persons With Type 1 Diabetes Over the 5year Study.

    year 1, 3, 5 and after the washout phase (5years and 1month)

Study Arms (3)

Dippers - Placebo Treated

PLACEBO COMPARATOR

Subjects with normal nighttime blood pressure profile that decreases at night (Dippers). This group are all given placebo.

Drug: Placebo

NonDippers - Placebo Treated

PLACEBO COMPARATOR

Subjects with nighttime blood pressure that does not drop during the night (non-dippers). This group will be given placebo.

Drug: Placebo

NonDippers - Ramipril Treated

ACTIVE COMPARATOR

Subjects with nighttime blood pressure that does not drop during the night (non-dippers). This group will be given ACE inhibitor (study medication).

Drug: Ramipril

Interventions

ACE inhibitor known as Ramipril Subjects with nighttime blood pressure that does not drop during the night ("non-dippers") maybe randomized into this group and given an ACE inhibitor (study medication). Therefore, the "Non-Dippers" groups II and III will be randomized to receive either drug or placebo.

Also known as: ACE Inhibitor
NonDippers - Ramipril Treated

Dippers (category of subjects with a nighttime dip in blood pressure) will all be given Placebo. Control group.

Dippers - Placebo Treated

Eligibility Criteria

Age13 Years - 50 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Subjects with type 1 diabetes confirmed by C peptide measurements.
  • Male and Female subjects of all races will be included in this study.
  • Subjects age must be between 13 to 50 years
  • Duration of the disease (from time of diagnosis of diabetes) must be between 5 to 28 years.
  • Subjects must be normotensive defined as a systolic blood pressure of ≤ 130 mmHg and diastolic of ≤ 85 mmHg in subjects 18 and older and for children (ages 13-17) blood pressure will be in the normal range based on standard tables which takes in to account gender, height and age.
  • The mean 24 blood pressure must meet the same criteria as the office blood pressures outlined above.
  • Subject must have normoalbuminuria (UAE \< 30 mg/24 hrs)
  • If subject is a female she must not be breast-feeding, and not of child-bearing potential, defined as post-menopausal for at least 1 year or surgically sterile; if she is of child bearing potential, then she must be practicing one of the following methods of birth control: 1) condoms, sponge, foams, jellies, diaphragm or intrauterine device (IUD), 2) contraceptives (oral or parenteral) initiated three months prior to study drug administration, 3) maintain a monogamous relationship with a vasectomized partner, or 4) total abstinence from sexual intercourse.

You may not qualify if:

  • Type 2 diabetics and other types of diabetics such as those with maturity onset diabetes or the young (MODY) will be excluded on the basis of established clinical criteria.
  • Subjects who have a history of hypertension or is taking any hypertensive medications.
  • Subjects who have a history of taking ACE inhibitors within the last six months or have a current indication for ACE inhibitor therapy.
  • Subjects (18 years of age and over) with a current blood pressure above 130mmHg/85mmHg. Subjects (13-17 years of age) who do not meet the normal range based on the standard tables
  • Subjects who are currently microalbuminuric i.e. 24hr albumin \> 30mg
  • Subjects who have participated in an interventional clinical trial involving ABPM 6 months prior to this study.
  • Subjects that have a diagnosis of chronic atrial fibrillation.
  • Subjects with a lifestyle that would disrupt normal circadian rhythm (i.e. night-shift workers).
  • Subjects with a current serious co-morbid condition for which life expectancy is \<2 years.
  • Subjects with a history of non-compliance, or psychiatric disturbance that would preclude successful completion of the study.
  • Inability to give informed consent.
