About

The purpose of this first-in-human study is to investigate the safety and tolerability of ABY-035 when administered intravenously and subcutaneously, to healthy volunteers and to psoriasis patients.

Full description

This first in human study with ABY-035 (a novel IL-17A inhibitor (interleukin 17A)) consists of four Parts. Part A consists of a single ascending intravenous dose study with 40 healthy volunteers divided into five dose cohorts. Each group consists of 8 subjects where 6 subjects will receive ABY-035 and 2 will receive placebo. The subjects will be followed for pharmacokinetic and safety assessments up to Day 95 after dosing. Part B of the study consists of 6 healthy volunteers who will be given a single subcutaneous dose of ABY-035. The subjects will follow the same study visit schedule as Part A. Part C of the study will include up to 12 moderate-to-severe psoriasis patients who each patient will be given a single intravenous dose of ABY-035. The patients will follow the same study visit schedule as Part A and B. Part D of the study will include up to 18 psoriasis patients (mild, moderate or severe). Each patient will participate in 3 or 7 biweekly dosing occasions of subcutaneously administered ABY-035. Patients will be followed regularly for safety, efficacy and pharmacokinetics for 8 weeks post-final dose.

  • Body mass index (BMI) between 18.0 kg/m2 and 32.0 kg/m2, inclusive. maximum body weight of 120 kg
  • In good health, as determined by medical history, physical examination, vital signs assessment, 12 lead electrocardiogram (ECG) and clinical laboratory evaluations.
  • Subjects will have given their written informed consent to participate in the study

In addition for Part C and D

  • Part D: Have at least one psoriatic lesion

Exclusion criteria

In addition for Part C and D

  • Patients who currently have non plaque forms of psoriasis (eg, erythrodermic, guttate, or pustular)
  • Patients who have current drug induced psoriasis
  • Have any history of any use of or have participated in clinical trials for any therapeutic agent directly targeted to any IL 17 cytokine or receptor
  • Have received phototherapy within 4 weeks prior to Day 1

  • Patients who have used topical medications and treatments that could affect psoriasis or PASI evaluation (eg, corticosteroids, coal tar, anthralin, calcipotriene, topical vitamin D derivatives, retinoids, tazarotene, methoxsalen, and trimethyl psoralens) within 2 weeks of administration of IMP (Investigational Medicinal Product)
  • Patients who have used any systemic immunosuppressants (eg, methotrexate, azathioprine, cyclosporine, 6 thioguanine, mercaptopurine, mycophenolate mofetil, hydroxyurea, or tacrolimus) within 8 weeks of administration of IMP (or 5 half lives, whichever is longer).
