A Real-world Study of Deucravacitinib in the Treatment of Moderate to Severe Plaque Psoriasis With Eczematous Features

Emerging evidence indicates that psoriasis and eczema can coexist in the same patient, with reported co-prevalence rates ranging from 0.17% to 20%, suggesting that these conditions may represent a disease spectrum-referred to as Psoriasis Eczema (PsEma). Moreover, paradoxical eczema has been observed in approximately 1% to 12.1% of psoriasis patients undergoing biologic therapy, with up to 61% of affected individuals discontinuing treatment due to eczematous flares. These findings underscore an urgent need for therapeutic agents that are efficacious for PsEma. Tyrosine kinase 2 (TYK2), a member of the Janus kinase (JAK) family, is known to mediate critical signaling pathways involved in psoriasis pathogenesis, including those of type I interferons, interleukin (IL)-12, and IL-23. Additionally, TYK2 forms heterodimers with other JAK family members-such as JAK1 or JAK2-to transduce signals from cytokines like IL-13 and IL-22, which are centrally implicated in the pathophysiology of eczema. Based on this molecular profile, we hypothesize that TYK2 inhibition may not only avoid inducing eczematous reactions in psoriasis patients but may also alleviate eczematous inflammation by interfering with JAK1(JAK2)/TYK2-mediated IL-13 and IL-22 signaling. Deucravacitinib, a selective allosteric TYK2 inhibitor, has shown promising results in our clinical practice, demonstrating improvements in both psoriatic and eczematous manifestations among patients with PsEma. This study aims to prospectively evaluate the efficacy and safety of deucravacitinib in PsEma patients over a 16-week treatment period. In parallel, transcriptomic profiling of peripheral blood and lesional skin will be performed to elucidate the immunological landscape and molecular signatures underlying PsEma, thereby contributing valuable clinical and mechanistic insights into its diagnosis and management.

SHR0302 Combined With PD-1/PD-L1 Inhibition for Treatment naïve or Acquired Resistant to Immunology NSCLC

Recent studies showed that the dysregulated activation of the JAK/STAT pathway, which leads to the prolonged release of IFN-γ, is a significant contributor to the resistance to immune checkpoint inhibitors in cancer immunotherapy. Preclinical and clinical studies have demonstrated that the combination of JAK inhibitors with PD-1 immunotherapy can reverse or delay onset of immunotherapy resistance by modulating the JAK/STAT pathway in Hodgkin's lymphoma and non - small cell lung cancer (NSCLC). SHR0302, being a highly selective JAK1 inhibitor, has shown excellent clinical benefits by effectively inhibiting the JAK/STAT pathway, leading to its approval for the treatment of Ankylosing Spondylitis in China. Preclinical studies also show that the combination of SHR0302 and PD-L1 inhibitor has synergistic potentials for anti-tumor effect in resistant to-immune checkpoint blockade patients. Thus, we conducted a phase 2 clinical trial evaluating SHR0302 combined with PD1/PD-L1 inhibitors as treatment-naïve or acquired resistant to first-line checkpoint inhibitor resistant NSCLC patients.
