ICS 2018: Extended Initial Uninterrupted Sleep Period for Older Patients After Treatment with AV002, an Emulsified Microdose Vasopressin Analog

Philadelphia, PA (UroToday.com) Dr. Brucker presented their work on the effect of the AV002 and the percentage of night with <1 NOV in patient > or equal to 65 and more than or equal 75 years in phase 3 RCT. As we know nocturia associated with disrupted sleep, reduced productivity, and negative impacts on overall health and health-related quality of life. The first uninterrupted sleep period (FUSP) is defined as the time from bedtime to first nocturic void (NOV) or awakening if no void occurred. The first 3-4 hours of sleep includes deep, slow wave, restorative sleep, which is correlated with improved productivity the next day. AV002 is an emulsified microdose vasopressin analog nasal spray approved for the treatment of nocturia due to nocturnal polyuria (NP).

Patients with a history of ≥2 NOVs per night for ≥6 months (n=1333) were randomized to AV002 1.66mcg, AV002 0.83mcg, or placebo and treated for 12 weeks. FUSP and the percentage of nights with ≤1 NOV were measured. Safety evaluations included adverse events (AEs) and incidence of hyponatremia (moderate hyponatremia is defined as serum sodium 126-129 mmol/L and severe hyponatremia as ≤125 mmol/L).

By end of study, in both age groups the increase in FUSP (Table 1A)

Table 1A

and percentage of nights with ≤1 NOV (Table 1B)

Table 1B

from baseline were statistically significant compared to placebo in both treatment groups.

Incidence and severity of AEs in the AV002-treated groups were similar to placebo. The incidence of hyponatremia was low for both doses (Table 2).

Table 2

Both ≥65y and ≥75y patients treated with AV002 demonstrated significant improvement in duration of first uninterrupted sleep period and percentage of nights with ≤1 nocturic void. For both age groups, the mean first uninterrupted sleep period after treatment was greater than 4 hours for 1.66mcg group and approximately 4 hours for 0.83mcg group. No patients treated with 0.83mcg (recommended starting dose for patients ≥65 years old) had severe hyponatremia. These results suggest AV002 is an effective therapy with a favorable safety profile in older adults with noctria due to nocturnal polyuria.

In conclusion, addressing nocturia in older adults may result in better quality of sleep, increased productivity during the day, and improved overall health and health-related quality of life.
