About this trial
This pilot phase 2 study evaluate the effectiveness and safety of pembrolizumab and lenvatinib in patients with anaplastic thyroid cancer. Patients with anaplastic thyroid cancer who are treatment-naive (BRAF-negative) and who were previously treated with chemptherapy or targeted therapy are scheduled to undergo pembrolizumab and lenvatinib and evaluate the outcomes according to the primary and secondary endpoints.

Single group
Treatments tested in this trial
Pembrolizumab + Lenvatinib
DrugPembrolizumab is a programmed death receptor-1 (PD-1)-blocking antibody. Lenvatinib is Lenvatinib is a kinase inhibitor that inhibits the kinase activities of vascular endothelial growth factor (VEGF) receptors VEGFR1 (FLT1), VEGFR2 (KDR), and VEGFR3 (FLT4).
Treatment groups
Trial outcomes
Primary outcomes
Objective response rate
The proportion of participants with a partial or complete response to the therapy. It is determined according to the iRECIST criteria.
Progression-Free Survival
The time from the date of treatment initiation to the radiological progression or death of the patient for any reason.
Safety and Tolerability assessment (Incidence of Treatment-Emergent Adverse Events)
Safety assessment will be assessed on the basis of adverse events (according to CTCAE 5.0)
Secondary outcomes
Overall survival
The time from the start date of treatment to the death of the patient for any reason.
The assessment of conversion to resectability
The proportion of participants with an initially unresectable or potentially resectable tumor who have moved to a resectable during treatment.
