Study Details
Study Description
Brief Summary
This study evaluates the combination of lenvatinib with denosumab in bone-predominant metastatic Radioiodine Refractory Differentiated Thyroid Carcinomas. All patients will receive this combination of treatments.

Phase 2 |
Detailed Description
Patients are usually considered for directed therapy (radiotherapy and/or surgery and/or thermo-ablation) in case of symptomatic lesions or at high risk of local complications. They also usually receive systemic bone-directed agents (bisphosphonate or denosumab), despite sparse available data in the context of differentiated thyroid carcinomas (DTC). As bone-directed agents have no antitumor activity, patients may require additional treatments. To date, only sorafenib and lenvatinib have been approved in the treatment of advanced Radioiodine Refractory Differentiated Thyroid Carcinomas (RR-DTC).
Lenvatinib demonstrated efficacy in RR-DTC compared to placebo. While other kinase inhibitors appeared to be less effective in controlling bone metastatic disease compared to other soft tissue sites, lenvatinib showed, in a small number of patients, significant decrease in bone tumors size.
Even if both study drugs are indicated in the treatment of patients suffering from RR-DTC with bone metastases, it is of essential importance to confirm that lenvatinib can provide clinical benefit and antitumor activity when combined with denosumab in this population.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Trial arm Lenvatinib and Denosumab will be used in the indication of their respective SmPCs. Study treatments will be divided in fictitious cycles of 28 days. Lenvatinib and Denosumab will be administered as per investigator's decision, based on the data from their SmPC, at starting doses of 24mg once daily and 120mg once every 4 weeks, respectively. Dose modification guidelines of their respective SmPCs will apply. Lenvatinib should be started the day after the inclusion. It will be taken every day at the same time, preferentially in the morning. As in routine practice, all patients will be supplemented with daily doses of at least 500mg Calcium and 400IU Vitamin D, unless hypercalcemia is present. Patients will be encouraged to maintain good oral hygiene during treatment with Denosumab. Study drugs will be continued until a treatment discontinuation criterion is met. |
