NCT05800327

Brief Summary

This is a two-stage study of efficacy, safety, pharmacokinetics, pharmacodynamics, and immunogenicity of various doses of levilimab when administered intravenously and subcutaneously to healthy subjects and subjects with active rheumatoid arthritis resistant to methotrexate monotherapy. Aim of the Stage 1 is to study the tolerability, safety, immunogenicity, and main pharmacokinetic and pharmacodynamic parameters of levilimab after its single subcutaneous or intravenous administration at ascending doses to healthy subjects. Aim of the Stage 2 is to confirm the efficacy and safety of levilimab 648 mg IV Q4W in combination with methotrexate and levilimab 324 mg SC Q2W in combination with methotrexate in subjects with active rheumatoid arthritis, resistant to methotrexate monotherapy.

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Signed Informed Consent Form for participation in the study.
  • Malegender.
  • Age 18-45 inclusive at the time of signing the ICF.
  • Healthy status confirmed by the history, physical examination, and laboratory parameters.
  • The absence of a history and signs of alcohol abuse or substance addiction at the time of signing the ICF, and a negative alcohol saliva screening test in combination with a negative urine drug test.
  • The ability of the subject to follow the Protocol procedures, according to the Investigator.
  • The readiness of the subject and their sexual partners with a childbearing potential to use reliable contraceptive measures from the date of signing the informed consent form throughout the study period and for 4 weeks after the administration of the investigational product. This requirement does not apply to the subjects and their partners who have undergone operative sterilization or the female partners of a subject who have been menopausal for more than 2 years.
  • Readiness not to drink alcohol within 24 hours prior to and 70 days after the administration of the investigational product.
  • Signed ICF for participation in the study.
  • Men and women aged ≥ 18 on the ICF signing day.
  • Rheumatoid arthritis that meets the ACR 2010 criteria, confirmed not less than 24 weeks before the ICF signing date. In the event that a subject has been diagnosed with rheumatoid arthritis in accordance with the ACR 1987 criteria, the physician-investigator must confirm the diagnosis in accordance with the ACR 2010 criteria during the screening period, with this information included in the primary documentation, if this has not been done previously and is not documented.
  • Methotrexate therapy during the 12 weeks prior to the ICF signing date.
  • Use of methotrexate at a stable dose during the 4 weeks prior to the ICF signing date (the methotrexate dose should be 15-25 mg per week, methotrexate dose of 10 mg may be used in case of intolerability/toxicity of a higher dose).
  • Failure of methotrexate when used over the 12 weeks before the ICF signing date (according to the Investigator).
  • Swollen joint count ≥ 6 (out of 66); tender joint count ≥ 6 (out of 68).
  • +3 more criteria

You may not qualify if:

Model Details: The study design assumes two sequential stages corresponding to Phase I and Phase III studies. Stage 1 This is an open-label, single-center, non-randomized cohort study of the safety and tolerability, pharmacokinetics, pharmacodynamics, and immunogenicity of single intravenous or subcutaneous levilimab injections administered to healthy subjects at ascending doses (modified 3+3 design). Stage 2 This is a randomized, comparative, double-blind, controlled clinical study to assess efficacy, safety, pharmacokinetics, pharmacodynamics, and immunogenicity of levilimab when administered at repeated intravenous or subcutaneous doses in combination with methotrexate in subjects with active rheumatoid arthritis resistant to methotrexate monotherapy.
