ASDS 2024: New Phase III READY-4 Data Demonstrate Long-Term Safety and Efficacy of Galderma’s RelabotulinumtoxinA (Relfydess™)

Galderma today announced new phase III data from the READY-4 clinical trial, demonstrating the long-term safety of RelabotulinumtoxinA (Relfydess^™) for frown lines and crow’s feet after repeated injections.¹ The READY-4 study met its primary and secondary endpoints, with less than one in five participants experiencing treatment-related treatment-emergent adverse events (TEAEs), and all events deemed mild or moderate.¹ Efficacy and patient satisfaction were also maintained across multiple treatments.¹ The data were presented at the American Society for Dermatologic Surgery (ASDS) 2024 Annual Meeting, held in Florida from October 17-20.

Developed and manufactured by Galderma, RelabotulinumtoxinA is the first and only ready-to-use liquid neuromodulator created with PEARL^™ Technology that is designed to preserve molecule integrity to deliver a highly active, innovative, complex-free molecule.^6-8 Previously announced data from the READY clinical trial program have demonstrated that up to 39% of patients see effects from day one and up to 75% of patients maintain improvements for six months for frown lines and crow’s feet when treated with RelabotulinumtoxinA.^4,5,9

READY-4 is a phase III, multicenter, open-label study, designed to evaluate the safety of RelabotulinumtoxinA for the long-term treatment of moderate-to-severe frown lines and crow’s feet in more than 900 participants. Injections were administered at a minimum of 12 weeks apart, in up to four cycles over 12 months.^1,10

Results demonstrate the long-term safety of repeated RelabotulinumtoxinA injections, consistent with the safety profile observed in the phase III READY-1, -2 and -3 clinical trials.^1,4,9,11 TEAEs were all mild to moderate, reported by 18% of participants and with similar occurrence across cycles one to four (11%, 7%, 7%, and 10% in cycle one, two, three, and four, respectively).¹

Efficacy was also maintained, with most participants achieving none-or-mild wrinkle severity at one month, which was maintained across multiple treatments throughout 12 months. Participants also reported high treatment satisfaction at one month (=84%).¹

Additional data on RelabotulinumtoxinA were presented at ASDS, including:

• Data from the phase III READY-3 study, previously presented at the TOXINS 2024 conference, demonstrated that RelabotulinumtoxinA significantly improves both frown lines and crow’s feet, when treated alone or simultaneously, with long duration of effect for six months, a favorable safety profile, and high patient satisfaction^2,11
• Pooled data from a post-hoc analysis of the READY-1, -2 and -3 studies showed that there were similarly high rates of improvement for both frown lines and crow’s feet following treatment with RelabotulinumtoxinA in people with different skin types, ethnicity, and race, affirming its efficacy and safety across diverse populations³

As previously communicated, Galderma completed its European decentralized procedure for RelabotulinumtoxinA in July 2024, resulting in a positive decision, and national approvals are now under finalization. RelabotulinumtoxinA also received a marketing authorization in Australia earlier this year. Regulatory applications for RelabotulinumtoxinA for the treatment of frown lines and crow’s feet will continue to be submitted and assessed by additional authorities globally. The development of RelabotulinumtoxinA is a key outcome of our exciting and compelling innovation pipeline and Galderma is working to launch it in the markets in which it is approved in the first half of 2025.

Update on International Chamber of Commerce (ICC) arbitration

The arbitration proceeding initiated by Galderma against Ipsen at the ICC related to the territorial scope of the Azzalure^® and Dysport^® (abobotulinumtoxinA) commercial partnership under the 2007 European development and distribution agreement has now been completed. The Tribunal of the ICC issued a final award in October 2024, reaffirming the scope of Galderma’s exclusive distribution rights with respect to Azzalure^® and Dysport^®. The award confirmed Galderma’s rights to commercialize Azzalure^® and Dysport^® in certain additional countries, including in Eastern Europe and Central Asia, that had been in dispute between the parties but dismissed Galderma’s claim for monetary compensation related to the timing of the transfer of such rights. Galderma and Ipsen continue to work in close partnership to grow Azzalure^® and Dysport^® sales in the territories of their commercial alliance.

About RelabotulinumtoxinA

Pioneered by Galderma, RelabotulinumtoxinA is the first and only ready-to-use liquid neuromodulator created with PEARL^™ Technology that is designed to preserve molecule integrity.^6,7 PEARL^™ Technology is designed to deliver a highly active, innovative, complex-free molecule, with up to 39% of patients seeing effects from day one and up to 75% of patients maintaining improvements for six months.^4-7,9 RelabotulinumtoxinA is optimized for simple volumetric dosing, without reconstitution, to increase ease-of-use and help ensure consistent dose/volume every time.^6,7 It was entirely developed and manufactured by Galderma to expand its neuromodulator portfolio as part of the broadest Injectable Aesthetics portfolio on the market.
