E.2.3

Trial contains a sub-study

E.3

Principal inclusion criteria

The trial will enroll adult subjects of either sex with primary femorotibial osteoarthritis according to American College of Rheumatology (ACR) clinical and radiographic criteria who have Kellgren-Lawrence grades of 2 or 3 and a minimum joint space width (JSW) of ≥ 2.5 mm in the medial compartment.

Subjects must have pain in the target knee on most days and/or require symptomatic treatment of knee pain with paracetamol (acetaminophen), systemic non-steroidal anti-inflammatory drugs (NSAIDs) including COX-2 selective inhibitor (coxibs), or tramadol on most days of the previous month, and must have both:
* A history of pain due to OA in the target knee for at least 6 months, and
* Pain score for the target knee of 4 to 9 points in response to Question 1 of the WOMAC pain index(“how much pain have you had [in the target knee, over the past 48 hours] when walking on a flat
surface?”) at screening and baseline, after washout of at least 5-half-lives of analgesic medication(s): acetaminophen, topical or oral systemic NSAIDS, coxibs, opioids, and/or tramadol.

Women of childbearing potential must use a form of contraception with a failure rate of less than 1% per year throughout the trial.

E.4

Principal exclusion criteria

Main exclusion criteria are malalignment of > 5 degrees in the femorotibial axis of the target knee, clinical signs of inflammation (i.e., redness) in the target knee, i.a. administration of corticosteroids or hyaluronic acid into either knee within 6 months before screening, any plan for knee surgery (affecting either the target or the contralateral knee) within the next two years, concomitant conditions or treatments deemed to be incompatible with trial participation, contraindications to MRI scanning (including inability to fit in the scanner or knee coil), pregnancy or breastfeeding, participation in another clinical trial within the past 30 days, and legal incapacity or limited legal capacity.

Safety endpoints are:
* Nature, incidence and severity of local and systemic AEs

visual analogue scale (VAS) and a self-reported synovial fluid effusion (i.e., joint swelling) within 3 days following i.a. injection
* Changes in laboratory safety parameters, vital signs, 12-lead electrocardiogram (ECG) parameters, weight, and physical examinations
* Incidence of surgical interventions in the target knee (including any surgical revision, cartilage removal, or any other type of surgical intervention).
* Occurrence of binding and neutralizing antibodies to sprifermin/FGF-18

E.5.2.1

Timepoint(s) of evaluation of this end point

DBPC phase:
* Changes from baseline in the WOMAC total score and in the WOMAC pain, function, and stiffness: over 2 years
* Change from baseline in the 20-meter walk test: over 2 years
* Change from baseline in the PGA: over 2 years
* Change from baseline in minimal joint space width in the medial and lateral compartments as by X-ray: over 2 years
* Change from baseline in cartilage thickness in the medial and lateral compartments: over 2 years
