6. Adverse Reactions/Side Effects
The following clinically significant adverse reactions are described elsewhere in the labeling:
Urinary Retention [See Warnings and Precautions (5.1)].
6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction 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 practice.
In two double-blind, vehicle controlled clinical trials (CARDIGAN 1 and CARDIGAN 2) of 700 subjects 10 to 76 years of age (353 subjects treated with SOFDRA and 347 subjects treated with vehicle), 44% of subjects were male, 79% were White, 21% were Black, and 1% were Asian. A total of 618 subjects completed at least 6 weeks of treatment, including 307 subjects treated with SOFDRA and 311 subjects treated with vehicle.
Table 1 summarizes the most frequent adverse reactions (≥2%) in subjects with primary axillary hyperhidrosis treated with SOFDRA.
| Adverse Reactions | SOFDRA
(N = 353) n (%) | Vehicle
(N = 347) n (%) |
|---|---|---|
| Note: COVID-19 was observed in 8 (2%) SOFDRA and 2 (0.6%) vehicle subjects. | ||
| Dry mouth | 51 (14%) | 2 (0.6%) |
| Vision blurred | 30 (9%) | 1 (0.3%) |
| Mydriasis | 23 (7%) | 0 |
| Urinary retention | 8 (2%) | 0 |
Table 2 shows the local skin reactions reported ≥2%, which occurred more commonly in the SOFDRA group.

7. Drug Interactions
7.1 Anticholinergics
Coadministration of SOFDRA with anticholinergic medications may result in additive interaction leading to an increase in anticholinergic adverse effects [See Warnings and Precautions (5.2)and Adverse Reactions (6.1)] . Avoid coadministration of SOFDRA with other anticholinergic-containing drugs.
8. Use In Specific Populations
8.1 Pregnancy
Risk Summary
There are no available data with SOFDRA use in pregnant women to evaluate for drug-associated risks of major birth defects, miscarriage or adverse maternal or fetal outcomes. In animal reproduction studies, subcutaneous administration of sofpironium bromide to pregnant rats and rabbits during the period of organogenesis resulted in no significant adverse effects at doses 31 and 10 times, respectively, the maximum recommended human dose (MRHD) ( see Data).
The background risks of major birth defects and miscarriage for the indicated population are unknown. All pregnancies have a background risk of birth defects, loss, and other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Data
Animal Data
In an embryofetal development study in rats, sofpironium bromide was not associated with embryofetal lethality or fetal malformations at subcutaneous dose levels of 1, 3, and 10 mg/kg/day administered during the period of organogenesis. The maternal and fetal survival, growth and development no observed adverse effect level (NOAEL) was 10 mg/kg/day (31 times the MRHD based on AUC comparisons).
In an embryofetal development study in rabbits, sofpironium bromide was administered by subcutaneous injection to pregnant rabbits at doses of 0.4, 2 and 10 mg/kg/day during the period of organogenesis. Maternal toxicity as evidenced by decreased maternal body weight gain and feed consumption was observed in all sofpironium bromide treated groups. The decrease in maternal body weight was considered severe at 10 mg/kg/day and was associated with embryofetal lethality. The maternal toxicity NOAEL could not be established in the study. The NOAEL for embryo-fetal development toxicity was 2 mg/kg/day (10 times the MRHD based on AUC comparison). Fetal malformation was not observed with sofpironium bromide treatment at doses up to 10 mg/kg/day (57 times the MRHD based on AUC comparison) in rabbits.
In a pre- and postnatal development study, sofpironium bromide was administered by subcutaneous injection to pregnant rats at doses of 1, 3 and 6 mg/kg/day beginning on gestation day 6 through lactation day 20. Maternal toxicity associated with a 17% decrease in body weight gain noted at 6 mg/kg/day (approximately 19 times the MRHD based on AUC comparisons) when compared to the control group. No sofpironium bromide-related effects on prenatal and postnatal development, neurobehavioral or reproductive performance of offspring were noted at doses up to 6 mg/kg/day (approximately 19 times the MRHD based on AUC comparison).
8.2 Lactation
Risk Summary
There are no data on the presence of SOFDRA 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 SOFDRA and any potential adverse effects on the breastfed infant from sofpironium bromide or from the underlying maternal condition.
Sofpironium bromide was detected in milk following single subcutaneous administration to lactating rats ( see Data). When a drug is present in animal milk, it is likely that the drug will be present in human milk.
8.4 Pediatric Use
The safety, effectiveness, and pharmacokinetics of SOFDRA for the treatment of primary axillary hyperhidrosis have been established in pediatric patients 9 years of age and older [See Clinical Pharmacology (12.3)] . Use of SOFDRA in this age group is supported by evidence from two multicenter, randomized, double-blind, parallel-group, vehicle-controlled 6-week trials and two multicenter, open-label, 24-week and 48-week trials, which included 72 pediatric subjects 9 years of age and older [See Adverse Reactions (6.1)and Clinical Studies (14)] .
The safety and effectiveness of SOFDRA have not been established in pediatric patients younger than 9 years of age.
8.5 Geriatric Use
Clinical trials of SOFDRA did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.
In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.
10. Overdosage
In case of an overdose, remove the topically applied product with soap and water, and treat the symptoms and signs attributed to the overdose symptomatically. Consider contacting the Poison Center at 1-800-222-1222 for the latest recommendations.
11. Sofdra Description
SOFDRA (sofpironium) topical gel is an anticholinergic drug. Sofpironium bromide drug substance is a white to off white powder with the chemical name 3'(R)-[2(R) cyclopentylphenylhydroxy-acetoxy]-1'-methyl-1'-ethoxycarbonylmethyl-pyrrolidinium bromide, very soluble in chloroform and freely soluble in water, ethanol, acetonitrile, and methanol, molecular formula of C 22H 32BrNO 5, molecular weight of 470.4 g/mol, and the following structural formula:
SOFDRA is a clear to translucent, colorless to pale yellow viscous gel containing 12.45% (w/w) sofpironium (equivalent to 15% sofpironium bromide) in an airless bottle sealed with a multi-dose metered pump. Each pump delivers 72 mg of sofpironium (equivalent to 87 mg of sofpironium bromide) in 0.67 mL of gel. The inactive ingredients are citric acid, 77.2% v/v dehydrated alcohol, hexylene glycol, hydroxypropyl cellulose, and isopropyl myristate.
12. Sofdra - Clinical Pharmacology
12.1 Mechanism of Action
Sofpironium bromide is a competitive inhibitor of acetylcholine receptors that are located on certain peripheral tissues, including sweat glands. Sofpironium bromide indirectly reduces the rate of sweating by preventing the stimulation of these receptors.
12.3 Pharmacokinetics
Absorption
The pharmacokinetics of sofpironium were evaluated in adult patients with primary axillary hyperhidrosis following SOFDRA applied once daily to the underarms for 21 days. The mean ± standard deviation (SD) exposures of sofpironium in adults are presented in Table 3. There was no evidence of accumulation.
| PK Parameter | Adult Patients |
|---|---|
| C max(ng/mL) | 2.71 (6.94) |
| AUC 0-t(ng∙hr/mL) | 45.1 (85.1) |
| t max(hr) | 5.34 (5.45) |
Distribution
Plasma protein binding of sofpironium is around 34.8-37.8%. The major sofpironium metabolite (BBI-4010) had plasma protein binding around 2.3-3.7%.
Elimination
Specific Populations
The pharmacokinetics of sofpironium were not evaluated in pregnant patients or patients with hepatic or renal impairment.
Pediatric Subjects
The mean ± SD exposures of sofpironium after a single dose in pediatric subjects 9 years to 16 years of age are presented in Table 4. After 24 weeks of dosing, trough concentrations of sofpironium were low and there was no evidence of accumulation. The exposure to major metabolite (BBI-4010) in pediatric subjects was similar to sofpironium exposure in adults.
| PK Parameter | Pediatric Patients |
|---|---|
| t maxreported as median and range. | |
| C max(ng/mL) | 1.30 (3.16) |
| AUC 0-t(ng∙hr/mL) | 14.6 (35.0) |
| t max(hr) | 4.0 (0.9, 23.1) |
Drug Interaction Studies
No clinically significant differences in sofpironium pharmacokinetics were observed when used concomitantly with inhibitors of CYP3A4, OCT2, MATE1, or MATE2-K.
13. Nonclinical Toxicology
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
The carcinogenic potential of sofpironium bromide was assessed in a 2-year dermal mouse carcinogenicity study and a 2-year subcutaneous rat carcinogenicity study. There were no drug-related neoplasms associated with daily topical administration of sofpironium bromide topical gel to mice at doses of up to 20% sofpironium bromide (2 times and 11 times the MRHD based on AUC comparisons for males and females, respectively). No drug-related neoplasms were identified in rats administered daily subcutaneous doses up to 1.5 mg/kg/day (males) and 5.0 mg/kg/day (females) (4 times and 12 times the MRHD based on AUC comparisons for males and females, respectively).
Sofpironium bromide was not mutagenic in a bacterial mutagenicity assay (Ames assay) or clastogenic in an in vitro mammalian chromosomal aberration assay (human peripheral blood lymphocytes) or in an in vivo micronucleus assay in rats.
There were no sofpironium bromide-related effects on male or female fertility and early embryonic developmental endpoints in rats at subcutaneous doses up to 10 mg/kg/day (70 and 20 times the MRHD based on AUC comparisons for males and females, respectively).
14. Clinical Studies
Two randomized, vehicle-controlled multicenter trials, CARDIGAN 1 (NCT03836287) and CARDIGAN 2 (NCT03948646), enrolled a total of 701 subjects 10 years of age or older with primary axillary hyperhidrosis. All subjects were to have symptoms of axillary hyperhidrosis for at least 6 months' duration, produce at least 50 mg of sweat in each axilla (underarm) with a combined total of at least 150 mg over a 5-minute period, and have a Hyperhidrosis Disease Severity Measure-Axillary, 7-item scale score (HDSM-Ax-7) ≥3.
In the trials, 56% of subjects were female, 78% were White, and 20% were Black or African American; for ethnicity, 31% identified as Hispanic or Latino. Fewer than 1% of subjects were less than 12 years of age, 7% were 12 to 17 years of age, 91% were 18 to 64 years of age, and 1% were 65 years of age or older.
Subjects 12 years of age and older were asked to rate their underarm sweating severity and frequency since waking on the previous day ("since you woke up yesterday") on the 11-item HDSM-Ax Adult version instrument. The HDSM-Ax-7 scale score was calculated by taking an average of 7 items, where the scale score ranges from 0 to 4 with a higher score representing greater underarm sweating severity. The mean HDSM-Ax-7 scale score at Baseline was 3.5 in CARDIGAN 1, and 3.6 in CARDIGAN 2. The median gravimetric sweat production (GSP) over 5 minutes at Baseline was 214.1 mg in the SOFDRA arm and 228.6 mg in the vehicle arm in CARDIGAN 1, and 207.7 mg in the SOFDRA arm and 231.1 mg in the vehicle arm in CARDIGAN 2.
Subjects were randomized to receive either SOFDRA or vehicle applied once daily at bedtime to each axilla. The co-primary endpoints were the proportion of subjects having at least a 2-point improvement in the HDSM-Ax-7 scale score from Baseline to Day 43, and the change in GSP from Baseline to Day 43.
The results of CARDIGAN 1 and CARDIGAN 2 are presented in Table 5.
