Experimental: Pembrolizumab & Lenvatinib treatment
Pembrolizumab 200 mg will be administered as a 30 minute intravenous (IV) infusion every 3 weeks, in addition to 20 mg Lenvatinib by mouth every day of each 3 week cycle. Estimated average length of treatment per participant: 4 months.
200 mg Pembrolizumab by IV on Day 1 of each 3 week cycle.
Other Name: Keytruda®
20 mg Lenvatinib by mouth every day of each 3 week cycle
Other Name: Lenvima®
- Objective Radiographic Response Rate (ORR) [ Time Frame: Up to 12 months ]Response Evaluation Criteria in Solid Tumors (RECIST) based response rate. Complete Response (CR): Disappearance of all extranodal target lesions. All pathological lymph nodes must have decreased to <10 mm in short axis. Partial Response (PR): At least a 30% decrease in the sum of the longest diameter (SLD) of target lesions, taking as reference the baseline sum diameters. Progressive Disease (PD): SLD increased by at least 20% from the smallest value on study (including baseline, if that is the smallest). The SLD must also demonstrate an absolute increase of at least 5mm. (Two lesions increasing from 2 mm to 3 mm, for example, does not qualify). Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD.
- Duration of Response (DOR) [ Time Frame: Up to 12 months ]DOR, defined as the time from first documented evidence of Complete Response (CR) or Partial Response (PR) until disease progression or death due to any cause, whichever occurs first.
- Progression Free Survival (PFS) [ Time Frame: Up to 12 months ]PFS, defined as the time from initial treatment to the first documented disease progression according to RECIST 1.1, or death due to any cause, whichever occurs first.
- Overall Survival (OS) [ Time Frame: Up to 12 months ]OS defined as the time from initial treatment until death from any cause.
