FDA Approves Qbrexza
Dermira Receives FDA Approval for Qbrexza (glycopyrronium) Cloth to Treat Excessive Underarm Sweating
MENLO PARK, Calif., June 29, 2018 (GLOBE NEWSWIRE) -- Dermira, Inc. (NASDAQ:DERM), a biopharmaceutical company dedicated to bringing biotech ingenuity to medical dermatology by delivering differentiated, new therapies to the millions of people living with chronic skin conditions, announced today that the U.S. Food and Drug Administration (FDA) has approved Qbrexza (glycopyrronium) cloth, an anticholinergic indicated for the topical treatment of primary axillary hyperhidrosis in adult and pediatric patients 9 years of age and older.
Primary axillary hyperhidrosis, also commonly known as excessive underarm sweating, is a chronic medical skin condition that results in sweating beyond what is needed for normal body temperature regulation. The exact cause is unknown, but it affects nearly 10 million people in the United States, with both men and women having similar prevalence. Qbrexza (pronounced kew brex’ zah) is applied directly to the skin and is designed to block sweat production by inhibiting sweat gland activation.
“For years, dermatologists have been telling us of the need for new treatment options that address primary axillary hyperhidrosis given the stigma and burden associated with this condition,” said Tom Wiggans, chairman and chief executive officer at Dermira. “From the start, our goal was to develop an approach that went beyond masking a person’s excessive underarm sweating and instead focused on treating the condition in a clinically meaningful way. We partnered with dermatologists and the FDA during the development stage and listened to the people who have been living with this condition to understand how they would define a meaningful benefit. It is our hope that Qbrexza will not only provide the clinical benefit these sufferers have been seeking, but help to reduce the overall burden on their lives.”
The approval is based on results from two Phase 3 clinical trials, ATMOS-1 and ATMOS-2, which evaluated the efficacy and safety of Qbrexza in patients with primary axillary hyperhidrosis. Both trials assessed the absolute change from baseline in sweat production (the weight or amount of sweat a patient produced) following treatment with Qbrexza and the proportion of patients who achieved at least a four-point improvement from baseline in their sweating severity, as measured by the Axillary Sweating Daily Diary (ASDD), Dermira’s proprietary patient-reported outcome (PRO) instrument. The PRO was developed in consultation with the FDA and in accordance with the agency’s 2009 guidance on PRO instruments.
“Primary axillary hyperhidrosis is a condition that has negatively impacted many of my patients for most of their lives,” said Dee Anna Glaser, M.D., professor and interim chair, Department of Dermatology at Saint Louis University School of Medicine and a renowned hyperhidrosis expert. “I look forward to Qbrexza’s potential to be a meaningful treatment option that will not only reduce a person’s sweat, but will reduce the overall impact this condition has on their daily life.”
The most common side effects observed following topical application of Qbrexza to the underarms were dry mouth, dilated pupil (mydriasis), sore throat (oropharyngeal pain), headache, urinary hesitation, blurred vision, dry nose, dry throat, dry eye, dry skin and constipation. The most common local skin reactions were erythema, burning/stinging and pruritus.
Qbrexza is expected to be available nationwide in pharmacies beginning in October 2018. For more information, visit www.qbrexza.com.
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 million people.1 Of these, 65 percent, or nearly 10 million people, suffer from sweating localized to the underarms (axillary disease). Studies have demonstrated that excessive sweating often impedes normal daily activities and can also result in occupational, emotional, psychological, social and physical impairment.1,2

IMPORTANT SAFETY INFORMATION
Contraindications: Qbrexza is contraindicated in patients with medical conditions that can be exacerbated by the anticholinergic effect of Qbrexza (e.g., glaucoma, paralytic ileus, unstable cardiovascular status in acute hemorrhage, severe ulcerative colitis, toxic megacolon complicating ulcerative colitis, myasthenia gravis, Sjogren’s syndrome).
WARNINGS AND PRECAUTIONS
Worsening of Urinary Retention: Qbrexza should be used with caution in patients with a history or presence of documented urinary retention. Prescribers and patients should be alert for signs and symptoms of urinary retention (e.g., difficulty passing urine, distended bladder), especially in patients with prostatic hypertrophy or bladder-neck obstruction. Instruct patients to discontinue use immediately and consult a physician should any of these signs or symptoms develop. Patients with a history of urinary retention were not included in the clinical studies.
Control of Body Temperature: In the presence of high ambient temperature, heat illness (hyperpyrexia and heat stroke due to decreased sweating) can occur with the use of anticholinergic drugs such as Qbrexza. Advise patients using Qbrexza to watch for generalized lack of sweating when in hot or very warm environmental temperatures and to avoid use if not sweating under these conditions.
Operating Machinery or an Automobile: Transient blurred vision may occur with use of Qbrexza. If blurred vision occurs, the patient should discontinue use until symptoms resolve. Patients should be warned not to engage in activities that require clear vision such as operating a motor vehicle or other machinery, or performing hazardous work until the symptoms have resolved.
The most common adverse reactions seen in ≥2% of subjects treated with Qbrexza were dry mouth (24.2%), mydriasis (6.8%), oropharyngeal pain (5.7%), headache (5.0%), urinary hesitation (3.5%), vision blurred (3.5%), nasal dryness (2.6%), dry throat (2.6%), dry eye (2.4%), dry skin (2.2%) and constipation (2.0%). Local skin reactions, including erythema (17.0%), burning/stinging (14.1%) and pruritus (8.1%), were also common.
Anticholinergics: Coadministration of Qbrexza with anticholinergic medications may result in additive interaction leading to an increase in anticholinergic adverse effects. Avoid coadministration of Qbrexza with other anticholinergic-containing drugs.
INSTRUCTIONS FOR ADMINISTERING QBREXZA
Instruct patients to use one cloth to apply Qbrexza to both axillae by wiping the cloth across one underarm, ONE TIME. Using the same cloth, apply the medication to the other underarm, ONE TIME. Inform patients that Qbrexza can cause temporary dilation of the pupils and blurred vision if it comes in contact with the eyes.
Instruct patients to wash their hands with soap and water immediately after discarding the used cloth.
USE IN SPECIFIC POPULATIONS
Pregnancy: There are no available data on Qbrexza use in pregnant women to inform a drug-associated risk for adverse developmental outcomes.
Lactation: There are no data on the presence of glycopyrrolate or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Qbrexza and any potential adverse effects on the breastfed infant from Qbrexza or from the underlying maternal condition.
Renal Impairment: The elimination of glycopyrronium is severely impaired in patients with renal failure.
