Exclusion criteria
Exclusion criteria: 1. A history of /or presence of active cancer 2. Family history of retinoblastoma 3. Indication of aneurysmal bone cyst on MRI, cyst aspiration or histology 4.

| Main Objective: To assess whether a single I-040302 implantation at concentrations of 33 µg/mL, 67 µg/mL or 133 µg/mL in a volume of up to 30mL (i.e. delivering doses of up to 1 mg, 2 mg or 4 mg of TGplPTH1-34 respectively) can improve bone cyst healing at 6 months, versus a single injection of bone marrow aspirate or a single steroid injection.; Secondary Objective: To assess the safety and tolerability of I-040302 To assess the pharmacokinetics of PTH1-34 To assess antibody formation against PTH1-34 and TGp1PTH1-24 To assess the number of recurrent surgical interventions annually until 5 years after study treatment To assess the rate of bone cyst healing annually until 5 years after study treatment To assess the effects of I-040302 on bone growth in the affected limb annually until 5 years after study treatment To evaluate quality of life and functional ability ; Primary end point(s): The primary endpoint of the study is the cyst resolution at 6 months. The cyst resolution (blinded central evaluation) will be defined radiographically (based on MRI and X-ray) using:- • A reduction in Cyst Index of 1 point • 75% or more reduction in cyst volume The extend of cyst resolution at each time-point will be defined and assessed by an independent radiological panel, blinded to the treatment. An analysis of the 6 month cyst healing data will be undertaken once all subjects have completed the 6 month visit. A further analysis will be made after all subjects have completed one and two year follow-up. Thereafter, annual reporting of data from all available subjects will be conducted for 5 years after application of I-040302. Secondary Endpoint(s) • The change in cyst index at 6 months, and annually until 5 years after study treatment, compared to baseline i | — |
