Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
EQ121 capsule is an oral solid dosage form manufactured at strengths of 1 mg and 12 mg.
Each EQ121 Immediate release (IR) capsule contains EQ121 drug substance; mannitol, pregelatinized starch and microcrystalline cellulose as diluents; croscarmellose sodium as disintegrate; colloidal silicon dioxide as glidant; and magnesium stearate as lubricant.
Approximately 12 adults with RA on a stable oral MTX regimen (15-25 mg/week) will be participating in this study. Eligible participants in New Zealand will receive their weekly dose of oral MTX on Days 1 and 8 and 36 mg of EQ121 orally, twice daily (twelve hours apart) on study days 3 to 8.
Blood samples for the determination of EQ121 concentrations and corresponding PK analysis will be collected on Day 3, Day 7 and Day 8 at pre-dose (morning dose; within 30 minutes prior to dosing); and after the morning dose at 0.25, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8 and 12 hours.
Blood samples for determination of MTX concentration and corresponding PK analysis will be collected on Day 1 at pre-dose (30 minutes prior to dosing), and at 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8 and 12 hours post-dose, on Day 2 at 24 and 36 hours post-dose, and Day 3 at 48 hours post-dose; and on Day 8 at pre-dose (30 minutes prior to administering oral MTX and study drug together), 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, and 12 hours post-dose, on Day 9 at 24 and 36 hours post-dose and on Day 10 at 48 hours post-dose.
Samples may be used to determine concentration of drug metabolites.
Safety oversight will be provided by the Principal Investigator and Medical Monitor. A record will be maintained by the investigational site that will account for all dispensing and return of any used and unused study drug.
Adherence will be assessed using pill count of the capsules returned.

Sponsor has decided to discontinue the EQ121-010 sub-study 2 (Drug-drug interaction of EQ121 in adults with rheumatoid arthritis (RA) who are on a stable oral methotrexate (MTX) regimen), effective immediately. This results from a business decision to halt development of EQ121 in rheumatoid arthritis. This decision was not because of any newly identified safety signals or safety risks associated with EQ121.
