Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the LedRad trial is to determine the efficacy and durability of radiotherapy as treatment for patients with Ledderhose disease and to compare this to the natural course of Ledderhose disease.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Radiotherapy

Patients assigned to the Radiotherapy group are treated with electrons and will receive a total dose of 30 Gy.

Group Type EXPERIMENTAL

Radiotherapy

Intervention Type RADIATION

Patients randomized to the Radiotherapy arm will be treated with electrons and receive a total dose of 30 Gy (two separate courses of five daily fractions of 3.0 Gy each).

Sham Radiotherapy

Patients assigned to the sham-radiotherapy group will not actually receive radiation. For these patients the radiation is simulated.

Group Type PLACEBO_COMPARATOR

Sham Radiotherapy

Intervention Type OTHER

Patients randomized to the sham-radiotherapy will not be treated and the radiotherapy treatment will only be simulated.
