Description

Summary

This is a two-arm open-label study to evaluate the clinical and immunogenetic responses of patients with plaque or guttate psoriasis to treatment with guselkumab.

Official Title

Immunogenetic Profiling of Guselkumab for the Treatment of Plaque and Guttate Psoriasis

Details

Guselkumab (Tremfya®), an IL-23 inhibitor approved for the treatment of moderate-to-severe plaque psoriasis. Given the potential role of IL-23 in the pathogenesis of guttate psoriasis, guselkumab may be an effective option to treat the initial manifestation of guttate psoriasis. This is a two-arm open-label study to evaluate the clinical and immunogenetic responses of patients with plaque or guttate psoriasis to treatment with guselkumab. The primary objective of this study is to assess how treatment with guselkumab changes the immune milieu of the skin in patients with plaque or guttate psoriasis. The secondary objectives of this study are to assess how treatment with guselkumab affects the quality of life and extent of skin disease in patients with plaque or guttate psoriasis.

  • At least 18 years of age.
  • Diagnosis of guttate psoriasis.
  • Onset of guttate psoriasis within 12 months.
  • Body surface area (BSA) involvement greater than or equal to 5%.
  • PASI greater than or equal to 4.
  • Subject is considered a candidate for phototherapy or systemic therapy.
  • Subject is unlikely to conceive due to male, post-menopausal, or using adequate contraceptive (barrier, hormonal, implant, or permanent sterilization methods). Women of childbearing potential will be allowed to enroll provided they practice adequate forms of birth control.
  • Physical exam with no evidence of active skin infection and/or other findings that indicate chronic disease or concomitant inflammatory/immune-mediated skin disease other than psoriasis.

For subjects with chronic plaque psoriasis (control):

  • Ability to provide written informed consent and comply with the protocol.
  • At least 18 years of age.
  • Diagnosis of plaque psoriasis.
  • Duration of plaque psoriasis >5 years.
  • Body surface area (BSA) involvement greater than or equal to 5%.
  • Subject is considered a candidate for phototherapy or systemic therapy.
  • Subject is unlikely to conceive due to male, post-menopausal, or using adequate contraceptive (barrier, hormonal, implant, or permanent sterilization methods). Women of childbearing potential will be allowed to enroll provided they practice adequate forms of birth control.
  • Physical exam with no evidence of active skin infection and/or other findings that indicate chronic disease or concomitant inflammatory/immune-mediated skin disease other than psoriasis.
