Thank you, Carrie. In immunology, we had two important milestones in the third quarter for Skyrizi in inflammatory bowel disease. Following completion of the Phase 3 maintenance trial in ulcerative colitis, we submitted our regulatory applications for Skyrizi in this indication in the U.S. and Europe with approvals anticipated in 2024.
We also recently presented results from the SEQUENCE head-to-head trial comparing Skyrizi to Stelara in patients with moderate to severe Crohn's disease. We're extremely pleased with how Skyrizi performed in this study, which enrolled very difficult-to-treat patients who all failed anti-TNF therapy. Skyrizi met the primary and all secondary endpoints in the trial, demonstrating clear superiority to Stelara on all endpoints at week 48 and with a more than doubling of effect in endoscopic remission at 32% of Skyrizi versus 16% for Stelara and endoscopic response at 45% versus 22% for Stelara.
Furthermore, steroid-free clinical remission was 61% for Skyrizi versus 40% for Stelara. So these compelling head-to-head Crohn's data combined with the additional indication approval for ulcerative colitis expected next year will further position Skyrizi as a highly effective, durable, safe and well-tolerated treatment option for patients with moderate to severe inflammatory bowel disease.
We continue to make very good progress with the second wave of Rinvoq development programs as well in addition to the ongoing Phase 3 programs in GCA, lupus and HS, we recently began the Phase 3 program for Rinvoq in alopecia areata. We also recently announced positive top line results from a Phase 2 study for Rinvoq in vitiligo. In this study, Rinvoq met the primary and all secondary endpoints at week 24, demonstrating a significant improvement in both facial and total body vitiligo scoring measures compared to placebo.
Importantly, these results continued to improve through week 52 of the study, illustrating Rinvoq's potential to provide significant skin repigmentation to patients suffering from vitiligo. Based on these results, we're advancing Rinvoq to Phase 3 in this indication with studies expected to begin soon.
Moving to oncology, where in the quarter, we received approval in Europe and Japan for epcoritamab as a monotherapy treatment for patients with relapsed or refractory DLBCL, were received two or more systemic therapies. These approvals represent important regulatory milestones for EPCO, and we look forward to bringing this new subcutaneous treatment option to patients in these international markets. We also continue to make good progress with the development programs in earlier lines of DLBCL and follicular lymphoma and we look forward to providing updates on these programs as the data mature.
In our Venclexta multiple myeloma program, we recently announced top line results of a Phase 3 CANOVA trial evaluating Venclexta plus dexamethasone, compared to PomDex in relapsed/refractory patients with a T114 mutation. In this study, the primary endpoint of IR CSS PFS was longer with VenDex versus PomDex but did not meet statistical significance. accommodation also resulted in numerically higher response rates and longer overall survival compared to PomDex. While the differences in efficacy measures were not statistically significant, we believe the totality of the data show a benefit with the Venclexta combination and we plan to discuss the results with regulatory agencies. We'll provide updates on the program as they become available.
Behind Venclexta, we have several exciting multiple myeloma programs emerging from our earlier stage pipeline. We continue to make good progress with our BCMA CD3 bispecific ABBV-383, where we're nearing completion of the dose optimization work and are on track to begin Phase 3 studies in the first half of next year. At an upcoming medical meeting, we plan to present updated Phase 1 efficacy and safety results as well as monthly administration dose data. We're also making good progress with our next-generation BCL2 inhibitor, ABBV-53, which is currently in Phase 1 studies and we'll provide updates as the data become available.
Now moving to Neuroscience, where in the quarter, we received approval for Aquipta in Europe, which is now the only oral CGRP antagonist approved in Europe for prevention of both episodic and chronic migraine. And lastly, in our aesthetics pipeline, we recently announced top line results from a second Phase 3 study evaluating Botox in platysma prominence, similar to results from the first Phase 3 study, all primary and secondary endpoints were met with Botox demonstrating a significant reduction in platysma prominence and vertical neckband. We anticipate a regulatory submission in the U.S. here the end of the year.
In addition to indication expansion for Botox, we continue to advance our novel toxin pipeline. We recently announced positive top line results from two Phase 3 trials evaluating BoNT/E, our rapid onset, short-acting novel toxin in glabellar lines. BoNT/E performed very well in both studies meeting the primary and all secondary endpoints compared to placebo. BoNT/E was well tolerated and no safety concerns were identified. We're very pleased with these results, which demonstrate this toxin's rapid onset of action and short duration of effect. Patients treated with BoNT/E showed an improvement in glabellar lines as early as 8 hours following injection and a duration of effect of 2 to 3 weeks. This highly differentiated clinical profile could offer patients a novel option compared to currently available neurotoxins.
We plan to complete the remaining development work over the course of the next few quarters and anticipate submitting our regulatory applications in the second half of next year. So in summary, we continue to make good progress across all stages and therapeutic areas of our pipeline, and we look forward to several more important milestones in the remainder of this year, including Phase 2 data for Teliso-V and second line plus advanced non-squamous non-small cell lung cancer, which has the potential to support an accelerated approval. Phase 2 proof-of-concept data for our anti-IL-1 alpha beta bispecific antibody, lutikizumab in hidradenitis suprativa, and regulatory approval in Europe for ABBV-951, our novel subcutaneous levodopa, carbidopa delivery system for advanced Parkinson's disease. We also plan to submit updated 951 data in the U.S. near the end of the year.
With that, I'll turn the call over to Scott.
