Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Study CSL324\_1002 will investigate the safety and pharmacokinetics of repeat doses of CSL324 in subjects with hidradenitis suppurativa and palmoplantar pustulosis. CSL324 is a novel, recombinant therapy that may treat diseases caused by increased numbers of neutrophils at sites of inflammation.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Subjects with HS only: inadequate response to at least a 3-month (90 days) trial of oral antibiotics for treatment of HS
* Subjects with PPP only: confirmed clinical diagnosis of PPP at least 6 months before Screening and inadequate response to topical therapy, phototherapy, and / or previous systemic therapy for the treatment of PPP

Exclusion Criteria

* Treatment with any medications and therapies not permitted during the study.
* History of myeloproliferative disease.
* Malignancy within 5 years at Screening with the exception of nonmelanoma skin cancer, carcinoma in situ, or prostate cancer not requiring treatment.
* Current, or a recent clinically significant history of, uncontrolled renal, hepatic(including currently active hepatitis B virus and / or hepatitis C virus), hematologic, endocrine, pulmonary, psychiatric, or cardiac disease, assessed as potentially having an effect on study outcomes as determined by the Investigator and / or Sponsor.
* Congenital or acquired immunosuppressive condition(s), including human immunodeficiency virus infection.
* Clinical signs of active infection and / or fever \> 38°C during the 7 days before Day 1.
* Clinically significant abnormalities on physical examination, ECG, or laboratory assessments, or neutropenia (defined as absolute neutrophil count \< 2.0 × 109/L) at Screening.
* Subjects with PPP only: concurrent psoriasis vulgaris (not including scaly scalp and / or ears).
* Subjects with HS only: \> 20 draining fistulas."
