Phase 1 Study With KIN-1901 in Healthy Subjects and Subjects With Ankylosing Spondylitis

An Ascending Single- and Multiple-Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Subcutaneous Gimsilumab in Healthy Subjects and Subjects With Ankylosing Spondylitis

This study is intended to treat ankylosing spondylitis (AS). AS is a form of arthritis that primarily affects the spine. It is characterized by inflammation of the spinal joints that can lead to severe pain, and in more advanced cases, ankylosis (sections of the spine fuse in a fixed, immobile position). The study will be an ascending single and multiple-dose study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of subcutaneous KIN-1901 in healthy subjects and subjects with AS.

Study Overview

• Status: Completed
• Conditions: Inflammation; Rheumatic Diseases
• Intervention / Treatment: Drug: Placebo; Drug: KIN-1901

Detailed Description

KIN-1901 is a fully human immunoglobulin monoclonal antibody (mAb) directed towards a proinflammatory cytokine that is believed to have a role in inflammation and autoimmunity, and is found in synovial fluid from patients with spondyloarthritis. Therefore, neutralization of this cytokine activity by specific monoclonal antibodies (mAbs) could be beneficial in treating certain spondyloarthropathies such as ankylosing spondylitis (AS).

The primary objective of the study is to evaluate the safety and tolerability of escalating single-dose or once-weekly repeat-dose subcutaneous (SC) administration of KIN-1901 in healthy subjects (Cohorts 1 through 4) and in subjects with AS (Cohort 5). The secondary objective of the study is to evaluate the pharmacokinetics (PK) of escalating single-dose and once-weekly repeat-dose SC administration of KIN-1901 in healthy subjects (Cohorts 1 through 4) and in subjects with AS (Cohort 5). The following exploratory objectives will also be evaluated: (1) To explore the pharmacodynamic (PD) effects of escalating single-dose and once-weekly repeat-dose SC administration of KIN-1901 in healthy subjects (Cohorts 1 through 4), (2) To explore the PD effects and changes in disease activity by Assessment in Ankylosing Spondylitis Criteria ASAS 20/40 (and components) and Ankylosing Spondylitis Disease Activity Score-CRP (ASDAS-CRP) of once-weekly repeat-dose SC administration of KIN-1901 in subjects with AS (Cohort 5), (3) To assess biomarkers of efficacy and safety after once-weekly repeat-dose SC administration of KIN-1901 in subjects with AS (Cohort 5).

Description

Main Inclusion Criteria:

1. Capable of giving written informed consent, which includes compliance with study requirements and restrictions listed in the consent form.

2. Age requirements:

   • Cohort 5 (AS): Male or female age ≥ 18 years and ≤ 75 years.

3. Females must agree to use a highly effective birth control method (<1% failure rate per year) throughout the study, reproductive status of non-childbearing based on medical history, or is postmenopausal:

   • Non-childbearing potential defined as pre-menopausal female with medical history of bilateral tubal ligation, bilateral oophorectomy (removal of the ovaries) or hysterectomy; hysteroscopic sterilization,
   • Postmenopausal defined as 12 months of spontaneous amenorrhea; with follicle stimulating hormone (FSH) confirmation.
   • Woman of Childbearing potential (WCBP) who is already using an established method of highly effective contraception or agrees to use one of the allowed BC methods for at least 28 days prior to the start of dosing (as determined by the Investigator Brochure or Investigator or designee) to sufficiently minimize the risk of pregnancy throughout study participation (until completion their study follow-up visit).
4. Males who are sexually active must agree to use one of the allowed birth control methods. Male subjects must also agree to sufficiently minimize the risk of pregnancy throughout study participation (until completion their follow-up visit).

5. Body Mass Index (BMI):

   • Cohorts 1-4 (healthy): BMI 18.5 to 31 kg/m2 at Screening
   • Cohort 5 (AS): BMI 18 to 33 kg/m2 at Screening

   Additional Inclusion Criteria for Cohort 5 (AS) only:

6. AS diagnosis fulfilling the Modified New York criteria for AS.
7. Active AS, as defined by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≥ 4 despite NSAID, corticosteroid or DMARD therapy.
8. BASDAI, item 2, spinal pain score ≥ 4 (out of 10).

10. Does not have a history of complete spinal ankylosis.
11. CRP > ULN at Screening.
12. Two prior failures to NSAID therapy (sub-optimal clinical response following four weeks at maximum tolerated dose) or intolerance to NSAID therapy.

Main Exclusion Criteria:

An individual will NOT be eligible for inclusion in this study if any of the following criteria apply.

2. Disease diagnosis that may influence the outcome of the study; such as psychiatric disorders or disorders of the gastrointestinal tract, liver, kidney, respiratory system, endocrine system, hematological system, neurological system, cardiovascular system within 4 weeks prior to randomization, or individuals who have preexisting metabolic congenital abnormality(ies).
3. Positive Quantiferon test.
