Participants who continued to satisfy specified inclusion and exclusion criteria as presented in the study protocol.~3. Participants with maximum interval between the day of confirmation of PD by IIR and Cycle 1/Day 1 of the OOL Lenvatinib Treatment Period of less than or equal to 3 months.~4. No systemic anticancer treatment during the interval between the day of confirmation of PD by the IIR and Cycle 1/Day 1 of the OOL Lenvatinib Treatment Period.

Study Arms:
- Lenvatinib (Randomization Phase) (Type: EXPERIMENTAL): Participants randomly assigned in a 2:1 ratio to receive blinded study drug (lenvatinib or matching placebo) until documentation of disease progression (confirmed by IIR), development of unacceptable toxicity, or withdrawal of consent.
- Placebo (Randomization Phase) (Type: PLACEBO_COMPARATOR): Participants randomly assigned in a 2:1 ratio to receive blinded study drug (lenvatinib or matching placebo) until documentation of disease progression (confirmed by IIR), development of unacceptable toxicity, or withdrawal of consent.
- Lenvatinib 24 mg (OOL Lenvatinib Treatment Period) (Type: EXPERIMENTAL): Participants will receive lenvatinib 24 mg, orally once daily until documentation of disease progression (confirmed by investigator's assessment), development of unacceptable toxicity, or withdrawal of consent. Placebo treated participants in the Randomization Phase who have progressive disease confirmed by IIR could request to receive lenvatinib treatment in the OOL Treatment Period.
- Lenvatinib 20 mg (OOL Lenvatinib Treatment Period) (Type: EXPERIMENTAL): Participants will receive lenvatinib 20 mg, orally once daily until documentation of disease progression (confirmed by investigator's assessment), development of unacceptable toxicity, or withdrawal of consent. Placebo treated participants in the Randomization Phase who have progressive disease confirmed by IIR could request to receive lenvatinib treatment in the OOL Treatment Period.
