Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Desmopressin
Day 1 - participants continue desmopressin intranasal. Day 2 up to Day 4 - Desmopressin oral melt to optimum dose. Continue optimum dose for the four week treatment and one year follow-up periods.
 Drug: Desmopressin Oral Melt
Oral melt formulation starts on Day 2. The target initial dose of the orally disintegrating tablet is 180µg/day (60µg taken 3 times a day) and adjusted to optimally stabilise the participant's condition.
Other Names:
  • Minirin
  • FE992026

Drug: Desmopressin intranasal
Self-administered intranasal desmopressin throughout the pre-study observation period (Days -30 to Day 0) and on study Day 1

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Participants must be documented to have Central Diabetes Insipidus (CDI) by at least two of the following four criteria (a-d):

    1. Failure to increase urine osmolality above 300 mOsm/kg during a period of fluid deprivation sufficient to raise plasma osmolality and sodium above the upper limit of normal level for the reference laboratory (usually 295 mOsm/kg and 148 mEq/l, respectively)
    2. Complete and continuous control of the DI by desmopressin therapy without "breakthrough" diuresis, hypernatremia, hyponatremia, or symptoms or signs of water intoxication.
    3. A deficient plasma vasopressin response to osmotic or non-osmotic stimulation.
    4. Absence of the posterior pituitary bright spot on T-1 weighted midsagittal magnetic resonance imaging (MRI) of the brain.
  • Given written informed consent prior to any trial-related procedure is performed
  • 24 hour urine volume (mL), urine osmolality (mOsm/kg), urine specific gravity, and serum sodium (mEq/L) maintained at a normal level by desmopressin nasal administration
  • Outpatient
  • The participant is, in the investigator's opinion, otherwise healthy
  • Be willing and able to comply with the protocol requirements including restriction of water intake

Exclusion Criteria:

  • Presence or a history of nephrogenic diabetes insipidus or diabetes mellitus
  • Presence of uncorrected hypothyroidism, hypoadrenalism or hypogonadism
  • Abnormalities or disease of the oral cavity that might affect the release and absorption of drug
  • Unable to be placed on water-intake restriction starting from two hours before bedtime
  • Presence of a hypothalamus abnormality leading to thirst disorder
  • Evidence of hepatic, renal, cardiac, or pulmonary dysfunction
  • Uncontrolled hypertension
  • Treatment with another investigational product within the past 3 months
  • Concurrent treatment with diuretics, chlorpropamide, tricyclic antidepressants, indomethacin, carbamazepine
  • Alcohol dependency or drug abuse
  • Breastfeeding, pregnant, or likely to become pregnant
  • A mental condition, the lack of decision-making ability, dementia or a speech handicap
  • Any other reason that the Investigator believes inappropriate
