- Daily treatment with glycopyrronium tosylate in the Phase 3, open-label ARIDO trial was generally well-tolerated during 44 weeks of treatment
- Efficacy assessment suggests sweat reduction levels were maintained in patients treated with glycopyrronium tosylate during the extended study
After an additional 44 weeks of treatment, glycopyrronium tosylate was generally well-tolerated by most patients with a low rate of discontinuation attributed to treatment-emergent adverse events (TEAEs)*. These findings were consistent with those observed in previous trials. An efficacy assessment also suggests that patients treated with glycopyrronium tosylate in ARIDO experienced a sustained response to the investigational therapy during the 44-week treatment period. The newly reported findings were presented at the 36th Annual
Glycopyrronium tosylate is an anticholinergic agent, formulated for once-daily application using a topical wipe. Glycopyrronium tosylate is designed to block sweat production by inhibiting the receptors responsible for sweat gland activation.
“The findings from the ARIDO study are important in that they further demonstrate that glycopyrronium tosylate is generally well-tolerated, with a side-effect profile that is consistent with earlier studies,” said
ARIDO was designed to assess the long-term safety of glycopyrronium tosylate in adolescent and adult patients (ages nine and older) who participated in ATMOS-1 and ATMOS-2, two identical, Phase 3 clinical trials, which evaluated the safety and efficacy of the investigational therapy compared to vehicle for primary axillary hyperhidrosis over a four-week treatment period. Results from the ATMOS-1 and ATMOS-2 trials were reported in
Patients from the ATMOS-1 and ATMOS-2 trials were permitted to enroll in ARIDO to receive up to an additional 44 weeks of treatment with glycopyrronium tosylate. The majority of patients who completed the trials, or approximately 86.6% of patients (n=564), opted to receive treatment with glycopyrronium tosylate as part of the ARIDO study. Of the patients enrolled in ARIDO, 16.3% (n=92) were lost to follow-up, 14.5% (n=82) withdrew their consent, 7.8% (n=44) discontinued due to an adverse event and 2.5% (n=14) discontinued for other reasons. Additionally, 18.8% (n=106) were discontinued on treatment as
Phase 3 ARIDO Study Outcomes
- After an additional 44 weeks of treatment, 59.8% of patients (n=329) reported one or more TEAE, and most were considered mild or moderate in severity. The most frequently reported TEAEs observed in patients were dry mouth (16.9%; n=93), blurred vision (6.7%; n=37), application site pain (6.4%; n=35), the common cold (5.8%; n=32) and pupil dilation (5.3%; n=29). Prespecified anticholinergic TEAEs of interest, defined as those associated with a subset of anticholinergic side effects, were reported in 14.2% of patients (n=78) and most were mild or moderate in severity and were able to be managed by dose interruption. Serious TEAEs were reported in 1.3% of patients (n=7). The incidence of TEAEs, including prespecified anticholinergic TEAEs of interest, did not increase over time with longer duration of glycopyrronium treatment.
- An efficacy assessment conducted at the end of the treatment period in ARIDO suggests that patients who received glycopyrronium tosylate and completed the 44-week follow-up period maintained reduced sweat production compared to baseline and reported less bothersome sweating compared to baseline measures in ATMOS-1 and ATMOS-2. Notably, mean sweat production decreased by 95.77 ±140.8 mg/5 min and 63.2% of patients had ≥2-grade improvement in the Hyperhidrosis Disease Severity Scale (HDSS).
Hyperhidrosis is a condition of sweating beyond what is physiologically required for normal thermal regulation and affects an estimated 4.8% of the U.S. population, or approximately 15.3 million people.1 Of these, 65 percent, or nearly 10 million people, suffer from sweating localized to the underarms (axillary disease). Studies have further demonstrated that excessive sweating often impedes normal daily activities and can also result in occupational, emotional, psychological, social and physical impairment.2,3
