POS1079 Pharmacodynamic Response of JNJ-77242113 in Serum and Skin of Patients with Moderate-to-Severe Psoriasis: 1-Year Results from FRONTIER 1 & 2
Bibliographic record
Abstract
Background: JNJ-77242113 (JNJ-2113), a targeted oral peptide that binds the interleukin (IL)-23-receptor to inhibit IL-23 signaling, showed superior clinical efficacy vs placebo at Week(W) 16 of FRONTIER-1 in patients with moderate-to-severe plaque psoriasis, which correlated with strong serum and skin pharmacodynamic (PD) responses [1]. Objectives: To evaluate JNJ-2113 systemic PD responses through W52 and further characterize the JNJ-2113 skin PD effect, including relationships with clinical response, utilizing tape-strip skin sampling. Methods: FRONTIER-1 randomized (1:1:1:1:1:1) 41-43 participants per arm to 25mg once daily (QD), 25mg twice daily (BID), 50mg QD, 100mg QD, 100mg BID, or placebo through W16. Patients who continued in FRONTIER-2 received the same JNJ-2113 regimen, while those who were in the placebo group switched to the 100 mg QD dose, continuing for a total of 52-weeks of treatment. Both targeted (β-Defensin-2 [BD-2]/IL-22/IL-17A/IL-17F/IL-23) and broad (5400+ protein Olink® Explore HT) proteomics were conducted using serum samples collected through W52. The BD-2 and Olink® Explore-HT assays were performed on protein lysates extracted from tape-strip samples of lesional and non-lesional skin collected through W16, and the correlation between BD-2 levels and Psoriasis Area and Severity Index (PASI) scores was evaluated. Results: JNJ-2113 drove significant, rapid, dose-related reductions in serum psoriasis disease biomarker (BD-2/IL-22/IL-17A/IL-17F) levels that continued through W52; largest reductions were generally seen with JNJ-2113 100mg BID (W52 fold-change [FC] from baseline: -3.69/-1.19/-1.05/-1.46, respectively). Notably, through W52, JNJ-2113 had minimal impact on serum IL-23 (W52 FC from baseline: -0.13) or cytokines involved in broad immune response through W52 as assessed via Olink® Explore-HT. Consistent with serum results, JNJ-2113 100mg BID significantly reduced BD-2 levels in W16 lesional skin to levels seen in non-lesional skin; this reduction correlated with PASI. Broad proteomics of tape-strip samples showed baseline lesional samples were significantly enriched for psoriasis-relevant proteins (BD-2/IL-22/IL-17A/IL-19 and others) and clustered away from non-lesional samples. Importantly, JNJ-2113 100mg BID reduced psoriasis-related proteins in W16 tape-strip lesional samples, with a protein signature like non-lesional samples but distinct from baseline lesional and W16 placebo samples, suggesting JNJ-2113 attenuated skin inflammation. Conclusion: JNJ-2113 selectively blocked IL-23-driven inflammation and induced a dose-related PD response, with rapid and sustained reduction of biomarkers of the IL-23 pathway and psoriasis disease severity through 1-year of treatment. JNJ-2113 also attenuated skin inflammation with robust reduction in psoriasis-relevant disease biomarkers. Our novel approach to tape-strip derived proteomics demonstrates this minimally invasive alternative to skin biopsies can be used to evaluate disease biology and characterize local treatment response in psoriatic patients.
