Phase 1 Single and Multiple Dose Study of FPA008 in Healthy Volunteers and Rheumatoid Arthritis Subjects

A Phase 1, Randomized, Double Blind, Placebo Controlled, Single and Multiple Ascending Dose Study of FPA008 in Healthy Volunteers and Subjects With Rheumatoid Arthritis

This is a Phase 1, randomized, double-blind, placebo-controlled study designed in 3 parts to assess the safety, tolerability, and PK of single and multiple ascending doses of FPA008 in adult healthy volunteers (Parts 1 and 2) and adult subjects with active RA (Part 3).

Approximately 56 healthy volunteers will be enrolled at 1 study center in the Netherlands for Parts 1 and 2, and approximately 39 subjects will be enrolled at up to 6 sites in Central and Eastern Europe for Part 3. Dose escalations in Parts 1 and 2 will be driven by an assessment of the safety profile. Review of safety and PK parameters may inform decisions to add cohorts with intermediate dose levels in order to reach an optimal target exposure.

Inclusion Criteria:

Part 1 and 2:

• Healthy adult male and female subjects between the ages of 21-55 years inclusive.
• Subject must be willing to remain in the Clinical Research Unit (CRU) for a minimum of 72 hours after each dose.

Part 3:

• RA male and female subjects between the ages of 21-70 years inclusive
• Evidence of active RA disease
• Inadequate response to biologic or non-biologic DMARDs
• Subjects will be required to be on background therapy with methotrexate.

Exclusion Criteria:

Parts 1, 2 and 3:

• BMI <18 or >32 kg/m2
• Clinically significant findings in physical exams and laboratory tests at screening and/or baseline
• Unwilling to abstain from alcohol for 48 hours prior to study start, during CRU confinement, as applicable, and for 48 hours prior to study visits.
• Unwilling to abstain from exercise more strenuous than walking during CRU confinement, as applicable, and for 48 hours prior to study visits.

Parts 1 and 2:

• Use of any prescription, non-prescription, or herbal medications as well as supplements or vitamins within 4 weeks prior to dosing, unless approved by the Investigator.
• Smoking more than 10 cigarettes, or the equivalent, per day.

• Any surgical procedure including bone or joint surgery within 12 weeks prior to dosing
• Use of intra-articular (IA), intramuscular (IM), or IV corticosteroids for RA
• Neuropathies and neurovasculopathies
• Concomitant use of statins while on study.
