简要总结
The primary purpose of this study is to compare the progression-free survival (PFS) of participants with radioiodine (131 I)-refractory differentiated thyroid cancer (DTC) and radiographic evidence of disease progression within the prior 12 months treated with lenvatinib 24 mg by continuous once daily (QD) oral dosing versus placebo.
详细描述
This study will be conducted in 3 phases: a Prerandomization Phase, a Randomization Phase, and an Extension Phase. The Extension Phase will consist of the Optional Open Label (OOL) Lenvatinib Treatment Period and the Follow-up Period.

研究组 & 干预措施
Lenvatinib
In the randomization phase, participants will receive lenvatinib until disease progression. Participants who discontinue due to confirmed disease progression will enter Extension Phase. Participants who discontinue without confirmed disease progression will be followed for tumor assessment until confirmed disease progression or initiation of anticancer therapy, at which time the participants will enter Follow-up period of Extension Phase.
干预措施: Lenvatinib (Drug)
Placebo
In the randomization phase, participants will receive lenvatinib matched placebo until disease progression. Participants who discontinue due to confirmed disease progression will enter Extension Phase. Participants who discontinue without confirmed disease progression will be followed for tumor assessment until confirmed disease progression or initiation of anticancer therapy, at which time the participants will enter Follow-up period of Extension Phase.

结局指标
主要结局
Progression-free survival (PFS)
时间窗: From date of first dose of study drug until documentation of disease progression or death from any cause (whichever occurred first) or up to approximately 12 months
PFS is defined as the time from the date of randomization to the date of the first documentation of disease progression or death (whichever occurs first) as determined by blinded independent imaging review (IIR) conducted by the imaging core laboratory using Response Evaluation Criteria In Solid Tumors (RECIST) 1.1. Disease progression, per RECIST v1.1, is defined as at least a 20% relative increase and 5 millimeter (mm) absolute increase in the sum of the diameters of target lesions (taking as reference the smallest sum on study), recorded since the treatment started, or the appearance of 1 or more new lesions.
次要结局
- Overall survival (OS)(From date of first dose of study drug until date of death from any cause or up to approximately 36 months)
- Number of participants with treatment emergent adverse events (TEAEs) and serious adverse events (SAEs)(For each participant, from the time of administration of the first dose of study drug up to 30 days after the administration of the last dose of study drug or up to resolution of adverse event or up to study completion or up to approximately 36 months)
- Overall response rate (ORR)(From date of first dose of study drug until documentation of disease progression or death from any cause (whichever occurred first) or up to approximately 36 months)
