NOCDURNA SIDE EFFECTS

SIDE EFFECTS

The following adverse reaction is described elsewhere in the labeling:

• Hyponatremia

Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse event rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The safety database includes three double-blind, placebo-controlled, multicenter, randomized trials of NOCDURNA and one open-label extension trial. Study 1 (CS40) (NCT01262456) enrolled only women, Study 2 (CS41) (NCT01223937) enrolled only men, Study 3 (CS29) (NCT00477490) enrolled men and women and Study 4 (CS31) (NCT00615836) was an extension of Study 3 for up to 3 years.

At baseline, 196 women treated with NOCDURNA 27.7 mcg/day, 173 women given placebo, 195 men treated with NOCDURNA 55.3 mcg/day, and 213 men given placebo had nocturia due to nocturnal polyuria, with at least 2 nocturnal voids per night. The mean age of women treated with NOCDURNA 27.7 mcg was 59 years and 42% of women were aged 65 and older. The mean age of men treated with NOCDURNA 55.3 mcg was 62 years and 50% of men were aged 65 and older. Caucasians comprised 81%, Blacks 17%, and Asians 1% of the nocturia due to nocturnal polyuria population, and 12% were Hispanic.

Concomitant use of anti-muscarinic medications, alpha-blockers, and alpha-reductase inhibitors was permitted for patients on a stable dose prior to study entry. Serious adverse reactions included 2 reports of hyponatremia in men treated with NOCDURNA 55.3 mcg. These 2 reports occurred in a trial in which all cases of serum sodium <125 mmol/L were reported as serious adverse reactions.

Adverse Reactions Leading To Discontinuation

Among women with nocturia due to nocturnal polyuria, the discontinuation rate due to adverse reactions was 3% for those treated with NOCDURNA 27.7 mcg and 2% for those in the placebo group. Among men with nocturia due to nocturnal polyuria, the discontinuation rate due to adverse reactions was 4% for those treated with NOCDURNA 55.3 mcg and 3% in the placebo group.

Table 1 displays the most common adverse reactions leading to discontinuation in patients with nocturia due to nocturnal polyuria.

Most Common Adverse Reactions

Table 2 displays the most common adverse reactions in patients with nocturia due to nocturnal polyuria in Studies 1, 2, and 3. The most common adverse reactions reported with both the 27.7 mcg/day and 55.3 mcg/day dosages included dry mouth, hyponatremia or blood sodium decreased, and dizziness.

The high incidence of dry mouth may have been affected by specific query about dry mouth in Study 3 (CS29). In Studies 1 and 2 where the adverse reaction was spontaneously reported, the incidence was ≤4%.

Hyponatremia

Serum sodium was measured during screening, at baseline, and on all study visits during treatment including day 4, week 1, week 2 (males only), week 4 and then every month of the studies. Tables 3 and Table 4 show the incidence of serum sodium concentrations below the normal range based on the pooled analysis of three phase 3 studies.
