TOXINS 2024: Galderma’s Phase III RelabotulinumtoxinA Results Demonstrate Positive Efficacy and Long Duration of Effect When Treating Frown Lines and Crow’s Feet Simultaneously

Phase III READY-3 study met its co-primary endpoints, with RelabotulinumtoxinA significantly improving both frown lines and crow’s feet when treated alone or simultaneously[1]
Results demonstrate high patient satisfaction at one month and long duration of effect for six months[1]
Data further reinforce RelabotulinumtoxinA’s long duration of effect first observed in the phase III READY-1 and READY-2 trials, validating it as a well-tolerated and highly effective treatment for frown lines and crow’s feet[1-3]
READY-3 study results will be presented at the upcoming TOXINS 2024 conference, alongside data from Galderma’s broad portfolio of innovative neuromodulators, including Alluzience® and Dysport®

ZUG, SWITZERLAND--(Business Wire / Korea Newswire)--Galderma announced today positive topline results from the phase III READY-3 clinical trial investigating the use of RelabotulinumtoxinA for the treatment of glabellar lines (frown lines) and lateral canthal lines (crow’s feet), either alone (single-area) or simultaneously. The study met its co-primary endpoints, demonstrating that a single dose of RelabotulinumtoxinA significantly improves both frown lines and crow’s feet, when treated alone or simultaneously, with long duration of effect for six months.[1] These and other results from the READY phase III clinical trial program, as well as from Galderma’s broad and innovative aesthetics portfolio, will be presented at the TOXINS 2024 International Conference in Berlin, held from January 17-20, 2024.

“We’re looking forward to sharing the latest updates from our world-leading injectable aesthetics portfolio at TOXINS 2024, particularly first data from our phase III READY-3 trial. These results build on those previously seen in the READY-1 and READY-2 trials, further reinforcing RelabotulinumtoxinA’s ability to provide long-lasting improvement for frown lines and crow’s feet when treated simultaneously.”


The READY clinical trial program is composed of four phase III trials which enrolled more than 1,900 participants. READY-3 is a phase III randomized, double-blind, placebo-controlled trial designed to assess the safety and efficacy, as measured by aesthetic improvement, of RelabotulinumtoxinA in patients with moderate to severe frown lines or crow’s feet, either administered as a single-area treatment or simultaneously on both frown lines and crow’s feet, when compared to placebo. The trial met its co-primary endpoints, with patients and investigators reporting at least a two-grade improvement in line severity after single-area treatment of frown lines (71%) or crow’s feet (45%) and simultaneous treatment (72% frown lines and 55% crow’s feet), compared to placebo at one month (p<0.001).[1]

Investigator-reported response rates at one month were high, with 94-96% reporting none or mild frown lines when treated alone or simultaneously with crow’s feet, compared to placebo (2%, p<0.001), and 79-84% reporting none or mild crow’s feet when treated alone or simultaneously with frown lines, compared to placebo (20%, p<0.001). The median time of return to baseline line severity on both investigator- and patient-assessed scales was approximately six months after single-area (24-25 weeks) or simultaneous treatment (25-27 weeks), reinforcing previous results demonstrating the long duration of effect of RelabotulinumtoxinA. Patient satisfaction was high, with up to 91% reporting satisfaction with simultaneous treatment at one month. RelabotulinumtoxinA was well tolerated with low rates of treatment-related adverse events reported (4-9% compared to 5% for placebo); there were no serious treatment-related adverse events.[1]

“Patients often want their aesthetic look to last longer or to receive treatment on multiple facial areas simultaneously, and practitioners want to deliver consistent results for their patients. These new data highlight the ability of RelabotulinumtoxinA to address all these key needs for frown lines and crow’s feet, while also being a ready-to-use formulation that’s easy to administer.”


These results further reinforce the positive safety, efficacy and long duration of effect data observed in the READY-1 and READY-2 trials, which - together with recent phase IIIB results - also demonstrated RelabotulinumtoxinA’s rapid onset of action on frown lines and crow’s feet as early as day 1.[2-5] Data from the READY-1 and READY-2 studies will be presented at the TOXINS 2024 conference, highlighting that:[2,3]

· Both studies met their primary endpoints, with significantly higher responses than placebo after one month for both frown lines and crow’s feet.
· Results showed rapid onset of action, with over a third of patients seeing results on day 1 for frown lines (39%) and crow’s feet (34%), and demonstrated long duration of effect for six months.

RelabotulinumtoxinA is currently under investigation by Galderma and is not approved for any indication in any jurisdiction.

At the conference, Galderma will also present data from its broad and innovative neuromodulator portfolio, including:

· Results from the phase IV STAR study demonstrating the innovative science of Alluzience® (abobotulinumtoxinA solution) for the treatment of frown lines. In 81% of the treatment sessions, the investigators preferred Alluzience over onabotulinumtoxinA. The majority of patients maintained aesthetic improvement in frown lines and reported high satisfaction, including a natural and refreshed look, throughout six months.[6]
· Results from a phase IV non-interventional study investigating the real-world use of Dysport® (abobotulinumtoxinA) for the treatment of frown lines in 250 patients in China, reinforcing the long-term duration results and providing further evidence of Dysport use in clinical practice.[7]

Additionally, a Galderma-sponsored educational symposium on Alluzience will be chaired by Dr. Magdalena Korwin and Dr. Christoph Martschin, on Friday, January 19, from 3:35 - 4:05PM CET.
