Brief Summary:
Phase 2 study of the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and efficacy of KPL-404 in subjects with moderate to severe Rheumatoid Arthritis.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Arthritis, Rheumatoid | Drug: KPL-404 Drug: Placebo | Phase 2 |
This is a 28-week (up to 4-week screening period, 12-week treatment period, and 12-week safety follow-up period), multicenter, randomized, double-blind, placebo-controlled, multiple dose, proof-of-concept study with PK lead-in designed to assess the safety, PK, efficacy and PD of KPL-404 in subjects with moderate to severe, active Rheumatoid Arthritis (RA) who have an inadequate response to or are intolerant to a Janus kinase inhibitor (JAKi) AND/OR at least one biologic disease-modifying anti-rheumatic drug (bDMARD). The objectives of the study are to evaluate safety, efficacy, and PD of KPL-404 compared with placebo across the estimated therapeutic range and to characterize PK across varying dose levels of KPL-404.

Criteria
Inclusion Criteria:
- Body weight ≥ 40 to ≤ 140 kg for all cohorts.
- Diagnosis of RA for ≥ 3 months fulfilling the 2010 American College of Rheumatology (ACR)/European Union League Against Rheumatism (EULAR) classification criteria for RA and that is categorized as ACR RA functional Class 1-3.
- Treated with a biological disease-modifying anti-rheumatic drug (bDMARDs) AND/OR Janus kinase inhibitor (JAKi) therapy for RA for ≥ 3 months and had inadequate response or had to discontinue bDMARD AND/OR JAKi therapy due to intolerance or toxicity, regardless of treatment duration.
-
Currently receiving conventional synthetic disease-modifying anti-rheumatic drugs (csDMARD) therapy ≥ 3 months and on a stable dose for ≥ 4 weeks before the first dose of investigational product.
- The following csDMARDs are allowed: oral or parenteral methotrexate ([MTX]; 7.5 to 25 mg/week), sulfasalazine (≤ 3000 mg/day), hydroxychloroquine (≤ 400 mg/day), chloroquine (≤ 250 mg/day), and leflunomide (≤ 20 mg/day).
- A combination of up to 2 background csDMARDs is allowed, except the combination of MTX and leflunomide.

-
History of any of the following cardiovascular conditions:
- Moderate to severe congestive heart failure (New York Heart Association class III or IV);
- Recent (within past 6 months) cerebrovascular accident, myocardial infarction, coronary stenting;
- Uncontrolled hypertension as defined by a confirmed systolic blood pressure > 160 mmHg or diastolic blood pressure > 100 mmHg.
- Clinically relevant or significant electrocardiogram (ECG) abnormalities, including ECG with QT interval corrected for heart rate (QTc) > 500 msec.
