Sofpironium bromide (BBI 4000) is an anticholinergic agent used in the study of primary axillary hyperhidrosis (PAH). Sofpironium bromide reduces sweating by inhibiting M3 muscarinic receptors in eccrine glands at the application site. Sofpironium bromide also has a high afnity for the M1, M2, M4 and M5 subtypes[1].
Sofpironium bromide is metabolized mainly through non-enzymatic hydrolysis, and also through oxidative metabolism via CYP2D6 and CYP3A4[1].
Sofpironium bromide exhibits anticholinergic activity by inhibiting the contractile activity of guinea pig ileal tissue in a concentration-dependent manner. In a rat model, Sofpironium bromide reduces footpad sweating induced by Pilocarpine (a muscarinic receptor agonist)[1].

Sofpironium bromide: First Approval
Drugs 2020 Dec;80(18):1981-1986.PMID:33236266DOI:10.1007/s40265-020-01438-1.
Sofpironium bromide (ECCLOCK® in Japan) gel is a topical anticholinergic agent developed by Bodor Laboratories and licenced to Brickell Biotech for the treatment of hyperhidrosis. The drug is designed to reduce sweating by inhibiting M3 muscarinic receptors in eccrine glands at the application site. In September 2020, Sofpironium bromide gel 5% received its first approval in Japan for the treatment of primary axillary hyperhidrosis (PAH). Clinical studies are currently ongoing in the USA to assess the safety and efficacy of Sofpironium bromide gel 15% in PAH. This article summarizes the milestones in the development of Sofpironium bromide gel leading to this first approval for the treatment of PAH.
Sofpironium bromide: an investigational agent for the treatment of axillary hyperhidrosis
Expert Opin Investig Drugs 2022 Jan;31(1):15-21.PMID:34890517DOI:10.1080/13543784.2022.2017880.
Introduction: In recent years, increased knowledge about pathophysiology of primary hyperhidrosis has led to novel therapeutic advances. Topical and systemic anticholinergic agents have been proven beneficial in reducing sweat production in primary axillary hyperhidrosis (PAH), although their use is limited by the increased likelihood of systemic anticholinergic drug reactions, particularly regarding systemic agents. Areas covered: This paper provides an overview of pharmaceutical characteristics, efficacy and safety data from phase II and III clinical trials on Sofpironium bromide (SB), a topical anticholinergic agent that has been employed for the treatment of PAH and has already received its first approval in Japan for the treatment of PAH in the form of 5% gel formulation. Expert opinion: The retrometabolic drug design of topical SB presents distinct advantages, by limiting systemic absorption and therefore development of anticholinergic adverse events. This along with the popularity of the non-greasy gel formulation is expected to increase compliance. However, this therapy still offers a temporary control of PAH, compared to sympathectomy or device-based treatments, such as microwave thermolysis. Hence, physicians should balance the effectiveness against adverse events of each therapeutic modality and use a personalized approach based on patient's needs.
Two-week prospective observational study of 5% Sofpironium bromide gel in Japanese patients with primary axillary hyperhidrosis
J Dermatol 2022 Jun;49(6):594-599.PMID:35394087DOI:10.1111/1346-8138.16384.
In 2020, 5% Sofpironium bromide (ECCLOCK® ) gel (hereinafter referred to as sofpironium) was approved in Japan for the topical treatment of primary axillary hyperhidrosis. A phase III study of sofpironium demonstrated the efficacy and safety of sofpironium; however, no study has assessed its early efficacy at <6 weeks after starting treatment. Therefore, to assess the earlier effectiveness of sofpironium, we conducted a 2-week, single-center, exploratory, prospective, observational study in Japanese patients with primary axillary hyperhidrosis. Patients aged ≥20 years and satisfying with a Hyperhidrosis Disease Severity Scale (HDSS) score of 3 or 4 at baseline were eligible for the study. The primary endpoint for the effectiveness was change in the proportion of patients with a HDSS score of 1, 2, 3, or 4 during the 2-week study period. In 80 patients included in the full analysis set (FAS), there were more women than men (93.8% vs. 6.3%), and the mean age (±standard deviation [SD]) was 33.3 ± 9.4 years. In the FAS, the proportion of patients with a HDSS score of 1 or 2 was 55.0% on day 7, and statistically significant changes were observed after day 3 compared to baseline (p < 0.05). Mean HDSS scores (±SD) were significantly decreased from baseline value of 3.5 ± 0.5 to 2.4 ± 0.9 on day 7 (p < 0.001). The median period for sofpironium treatment to achieve a HDSS score of 1 or 2 for a continuous 2 days was 6 days (95% confidence interval, 4-8). Safety was evaluated in 92 patients in the safety analysis set, and no adverse events were reported during the study period of 2 weeks. These results suggest that after 1-week treatment with sofpironium for patients with a HDSS score of 3 or 4, approximately 50% of the patients can achieve a HDSS score of 1 or 2, which is a clinically significant improvement for the patients.
Efficacy of Sofpironium bromide gel on clozapine-induced hypersalivation in patients with treatment-resistant schizophrenia: double-blind, controlled crossover study
BJPsych Open 2023 Jan 13;9(1):e14.PMID:36636808DOI:10.1192/bjo.2022.630.
Background: Hypersalivation is a major side-effect of clozapine in patients with treatment-resistant schizophrenia. Aims: We investigated the efficacy of topical anticholinergic formulation Sofpironium bromide gel for improving hypersalivation in patients with treatment-resistant schizophrenia receiving clozapine. Method: A double-blind, controlled crossover study was conducted with Sofpironium bromide gel and a placebo gel to treat clozapine-induced hypersalivation in 16 patients with treatment-resistant schizophrenia. Patients were randomly divided between groups A and B (each n = 8). Group A was treated with Sofpironium bromide gel for 6 weeks, followed by a 2-week washout period and 6 weeks of placebo gel, after which they were observed for another 2 weeks. In contrast, group B was treated with placebo gel for 6 weeks, followed by a 2-week washout period, 6 weeks of Sofpironium bromide gel and a 2-week observation period. One-minute saliva volume, objective salivation ratings (Drooling Severity and Frequency Scale and Nocturnal Hypersalivation Rating Scale) and subjective salivation ratings (Visual Analogue Scale) were assessed every 2 weeks. Results: All patients completed the trials. Three patients reported mild, spontaneously resolved skin itching. Compared with baseline values, the 1-min saliva volumes of both groups were significantly decreased by approximately 30% at the second week of Sofpironium bromide gel treatment (P < 0.001), and significantly decreased by >40% at the fourth and sixth weeks of treatment (P < 0.001). The effects were maintained for over 2 weeks even after the treatment was discontinued. Conclusions: We suggest that Sofpironium bromide gel is effective in treating clozapine-induced hypersalivation in patients with treatment-resistant schizophrenia.
A phase 3, multicenter, randomized, double-blind, vehicle-controlled, parallel-group study of 5% Sofpironium bromide (BBI-4000) gel in Japanese patients with primary axillary hyperhidrosis
J Dermatol 2021 Mar;48(3):279-288.PMID:33410265DOI:10.1111/1346-8138.15668.
A phase 3 study was conducted to verify the efficacy and safety of 5% Sofpironium bromide (BBI-4000) gel (hereinafter referred to as sofpironium) administrated for 6 weeks in Japanese patients with primary axillary hyperhidrosis. The primary efficacy end-point was the proportion of patients who satisfied both criteria of a Hyperhidrosis Disease Severity Score (HDSS) of 1 or 2 at the end of 6-week treatment and a 50% or more reduction in total gravimetric weight of sweat at the end of treatment relative to baseline. A total of 281 patients were randomized to receive 5% sofpironium (141 patients) or vehicle (140 patients), and all patients were included in the full analysis set (FAS). In the FAS, 70.1% of patients were female, and the median age was 35.0 years. The proportion of patients who achieved the primary efficacy end-point was 53.9% in the sofpironium group and 36.4% in the vehicle group, with a statistically significant difference of 17.5% (95% confidence interval, 6.02-28.93) between these two groups (P = 0.003). The incidence of adverse events was 44.0% in the sofpironium group and 30.7% in the vehicle group, and the incidence of adverse drug reactions was 16.3% in the sofpironium group and 5.0% in the vehicle group. Reported adverse events were generally mild or moderate in severity. In the sofpironium group, common events (incidence, ≥5%) were nasopharyngitis (14.2%) and dermatitis/erythema at the application site (8.5%/5.7%), with no serious adverse events reported. This study demonstrated the efficacy and safety of 5% sofpironium.
