Details and patient eligibility

About

The purpose of this study is to determine whether intra-articular (knee joint) administration of MEN16132 is effective reducing the pain from knee osteoarthritis.

Full description

MEN16132 is a non-peptide bradykinin B2-receptor antagonist showing analgesic and anti-inflammatory activity in nonclinical osteoarthritis models. This study is being conducted as a dose finding study to determine the safety and efficacy of MEN16132, given as three doses/four treatment regimens in comparison to placebo, as well the time to onset and duration of effect.

Inclusion and exclusion criteria

Main Inclusion Criteria:

  • Male or female patients ≥40 years old.
  • Symptomatic primary knee osteoarthritis (ACR criteria) since ≥6 months prior to screening, Kellgren Lawrence Grade 2 or 3, and representing an indication for intra-articular drug injection.
  • >50 mm VAS pain score assigned to the index knee at WOMAC VA 3.1-A1 (pain while walking on a flat surface).
  • >125 mm VAS pain score assigned to the index knee at WOMAC VA 3.1 A subscore (total pain).
  • Pain in the index knee on at least 50% of the days in the month preceding the screening.

Main Exclusion Criteria:

  • Patients with Kellgren & Lawrence Grade I or IV (doubtful or severe) osteoarthritis of the knee.
  • Knee condition representing an indication for surgery
  • Patients with Inflammatory or crystal arthropathies, acute fractures, severe loss of bone density, bone necrosis.
  • Patients with isolated patella-femoral syndrome or chondromalacia.
  • Patients with OA predominant in the lateral compartment or any significant valgus deformity.
  • Patients with any other disease or condition interfering with the free use and evaluation of the index knee for the 3 month duration of the trial (e.g. cancer, congenital defects, spine osteoarthritis).
  • Major injury or surgery to the index knee within the previous 12 months prior to screening.
  • Severe hip osteoarthritis ipsilateral to index knee.
  • Any pain >30 mm VAS that could interfere with the assessment of index knee pain (e.g. pain in any other part of the lower extremities, pain radiating to the knee).
  • Any pharmacological or non-pharmacological treatment started or changed during 4 weeks prior to randomisation or likely to be changed during the duration of the study
  • Use of systemic or topical corticosteroids >10 mg prednisolone equivalent per day during 30 days prior to randomisation.
  • Use of any pain or OA medication (e.g. NSAIDs, COX-2 inhibitors, analgesics) during 1 or 2 weeks prior to randomisation.
  • Any intra-articular or local periarticular punction, injection or surgery to the index knee during the 6 months prior to screening.
