About this trial

This is an interventional treatment trial for Osteoarthritis, Knee

Eligibility Criteria

40 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Major inclusion criteria:

  • Aged ≥40 and ≤75 years at Screening
  • Radiological evidence of predominantly medial osteoarthritis in the knee, uni- or bilateral, of KL grade II to III
  • Moderate to severe pain associated with osteoarthritis in the knee as measured by a VAS pain score of ≥35 and ≤90 mm

Major exclusion criteria:

  • Body mass index (BMI) of ≥35 at Screening
  • Ongoing signs or symptoms of systemic or local infection
  • Known knee infection in the study knee within 6 months of Screening
  • History of clinically relevant concomitant joint disease, clinically-relevant knee deformities, or any clinically significant medical history of the ligament, or realignment surgery or joint replacement surgery
  • Medical history of any autoimmune disease
  • History of surgery in the study knee that occured within 6 months of Screening
  • Treatment with immunosuppressive therapy (systemic or local) or any medication affecting the bone or cartilage metabolism within 6 months of Screening
  • Patients who are immunocompromised as caused by a disease

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

XSTEM-OA

Arm Description

Single intra-articular injection of XSTEM-OA

Outcomes

Primary Outcome Measures

Safety and tolerability: Adverse events (AEs)
Incidence, nature and severity of treatment-related AEs assessed by the Common Terminology Criteria for Adverse Events (CTCAE)
Safety and tolerability: 12-lead electrocardiogram (ECG)
Change in 12-lead electrocardiograms (ECGs) compared to baseline.
Safety and tolerability: Laboratory examinations
Changes in laboratory tests compared to baseline. The clinical laboratory tests include haematology, chemistry, coagulation and urinalysis.
Safety and tolerability: Physical examinations
Changes in physical examination compared to baseline.
Safety and tolerability: Vital signs
Changes in vital signs compared to baseline. Vital signs include blood pressure, pulse rate, respiratory rate and oral body temperature.

Secondary Outcome Measures

Preliminary efficacy: Changes in Visual Analogue Scale (VAS) for pain compared to baseline
Preliminary efficacy: Changes in Knee injury and Osteoarthritis Outcome Score (KOOS) compared to baseline
Preliminary efficacy: Change in EuroQoL 5 Dimension 5 Level test (EQ-5D-5L) compared to baseline
Preliminary efficacy: Change in 40 m fast paced walk test compared to baseline
Preliminary efficacy: Change in cartilage structure compared to baseline, based on MRI assessment of cartilage volume and composition
Preliminary efficacy: Change in whole knee health compared to baseline, based on MRI assessment by the MRI Osteoarthritis Knee Score (MOAKS)
Preliminary efficacy: Change in inflammatory activity compared to baseline, based on MRI assessment of synovial thickness and synovial blood flow
Preliminary efficacy: Changes in joint space narrowing based on x-ray compared to baseline

5. Study Description

Brief Summary
The aim of the study is to assess safety, tolerability and preliminary efficacy of XSTEM-OA when administered as a single intra-articular injection to patients with symptomatic knee osteoarthritis. The study is divided into two parts; a dose escalation (Part A) and a dose expansion part (Part: B). Three dose levels are planned to be evaluated in Part A and selected dose level(s) will be further expanded in Part B.
