A Study to Determine the Metabolism and Elimination of 14C-E7080 in Patients With Advanced Solid Tumors or Lymphomas, Who Are Unsuitable For, or Have Failed, Existing Therapies.

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to determine the metabolism and elimination of 14C-lenvatinib in participants with advanced solid tumors or lymphomas, who were unsuitable for, or had failed, existing therapies.

Detailed Description
-----------------
The study comprised of two phases, the Study Phase and Extension Phase. Participants received 14C-lenvatinib on Day 1 of the Study Phase. Thereafter participants were given daily oral doses of 24 mg of lenvatinib over a 28 day cycle. During the Study Phase, participants received an initial single dose of 14C-lenvatinib oral patient dosing solution containing 24 mg of lenvatinib as anhydrous free base and radioactivity of 100 mCi (3.7 MBq) on Day 1, followed by collection of blood, urine and feces samples for pharmacokinetic analysis between Day 1 and Day 8, with a discharge visit on Day 8. Participants then entered the Extension Phase of the study to continue to receive once daily oral administration of non-radiolabeled lenvatinib at a dose of 24 mg. Each 28-day dosing period will be considered one treatment cycle.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Plasma Concentration (Cmax) of Radiolabeled 14^C-Lenvatinib and Non-Radiolabeled Lenvatinib | Blood samples were drawn at specific time points then analyzed for the amount of 14^C-lenvatinib and non-radiolabeled lenvatinib in the plasma. Individual blood/plasma concentration-time data were analyzed using 'non-compartmental' analysis. Cmax was determined from visual inspection of the individual blood/plasma concentration-time profile and was summarized as the Geometric Mean and percent coefficient of variation for the Geometric Mean (CV%) for all participants and expressed as nanograms/milliliter (ng/mL). | Day 1 (pre-dose, post-dose at 15 and 30 minutes, 1, 2, 4, 6, 8 and 12 hours), Day 2 (24 hours), Day 3 (48 hours), Day 4 (72 hours), Day 5 (96 hours), Day 6 (120 hours), Day 7 (144 hours) and Day 8 (168 hours) | 
| Time of Maximum Plasma Concentration (Tmax) of Radiolabeled 14^C-Lenvatinib and Non-Radiolabeled Lenvatinib | Blood samples were drawn at specific time points then analyzed for the amount of 14^C-lenvatinib and non-radiolabeled lenvatinib in the plasma. Individual blood/plasma concentration-time data were analyzed using 'non-compartmental' analysis. Tmax was determined from visual inspection of the individual blood/plasma concentration-time profile and was summarized as the Geometric Mean (CV%) for all participants and expressed as hours. | Day 1 (pre-dose, post-dose at 15 and 30 minutes, 1, 2, 4, 6, 8 and 12 hours), Day 2 (24 hours), Day 3 (48 hours), Day 4 (72 hours), Day 5 (96 hours), Day 6 (120 hours), Day 7 (144 hours) and Day 8 (168 hours) |

The terminal phase t1/2 is the time required to divide the plasma concentration of study drug by two after reaching pseudo-equilibrium, and not the time required to eliminate half of the administered dose of study drug. The t1/2 during the apparent terminal disposition phase was calculated at 0.693/λz and was summarized as the Geometric Mean (CV%) for all participants and expressed as hours. | Day 1 (pre-dose, post-dose at 15 and 30 minutes, 1, 2, 4, 6, 8 and 12 hours), Day 2 (24 hours), Day 3 (48 hours), Day 4 (72 hours), Day 5 (96 hours), Day 6 (120 hours), Day 7 (144 hours) and Day 8 (168 hours) | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Time t (AUC(0-t)) | Blood samples were drawn at specific time points then analyzed for the amount of 14^C-lenvatinib and non-radiolabeled lenvatinib in the plasma. The AUC(0-t) was calculated by the combination of linear/log (from Tmax) trapezoidal rule where 't' is the time of last quantifiable plasma concentration following dosing. AUC(0-t) was summarized as the Geometric Mean (CV%) for all participants and expressed in nanograms·hour/milliliter (ng·hr/mL). | Day 1 (pre-dose, post-dose at 15 and 30 minutes, 1, 2, 4, 6, 8 and 12 hours), Day 2 (24 hours), Day 3 (48 hours), Day 4 (72 hours), Day 5 (96 hours), Day 6 (120 hours), Day 7 (144 hours) and Day 8 (168 hours) |

| Percentage of Area Under the Plasma Concentration Curve Extrapolated to Infinity (%AUC(Extra)) | Blood samples were drawn at specific time points then analyzed for the amount of 14^C-lenvatinib and non-radiolabeled lenvatinib in the plasma. %AUC(extra) was calculated as [(AUC(0-inf) - AUC(0-t)/AUC(0-inf) ]*100 and was summarized as the Geometric Mean (CV%) for all participants and expressed in (ng·hr/mL). | Day 1 (pre-dose, post-dose at 15 and 30 minutes, 1, 2, 4, 6, 8 and 12 hours), Day 2 (24 hours), Day 3 (48 hours), Day 4 (72 hours), Day 5 (96 hours), Day 6 (120 hours), Day 7 (144 hours) and Day 8 (168 hours) | 
| Apparent Clearance (CL/F) of Lenvatinib From Plasma | Blood samples were drawn at specific time points then analyzed for the amount of 14^C-lenvatinib and non-radiolabeled lenvatinib in the plasma. The CL/F for parent lenvatinib only was calculated as Dose/[AUC(0-inf)] and was summarized as the Geometric Mean (CV%) for all participants and expressed in L/hr. | Day 1 (pre-dose, post-dose at 15 and 30 minutes, 1, 2, 4, 6, 8 and 12 hours), Day 2 (24 hours), Day 3 (48 hours), Day 4 (72 hours), Day 5 (96 hours), Day 6 (120 hours), Day 7 (144 hours) and Day 8 (168 hours) |

| Renal Clearance of Lenvatinib (CLr) | CLr was determined based on the interval amount and cumulative amount of the analyte excreted in the urine divided by its corresponding AUC over the same collection interval. Aeurine(0-t)/AUC(0-t), where t is the last measurable concentration, was calculated for lenvatinib only and was summarized as the Geometric Mean (CV%) for all participants and expressed in L/hr. | Pre-dose, post-dose at 0-6, 6-12, 12-18, 18-24, 24-30, 30-36, 36-42, 42-48, 48-72, 72-96, 96-120, 120-144, and 144-168 hours | 
| Percentage Recovery of 14^C- Lenvatinib Related Material in the Urine | Urine samples were collected at specific time points, then analyzed for the amount of 14^C- lenvatinib related material. The total radioactive dose of 14^C-lenvatinib excreted in urine (Aeurine%) was calculated from the time of dosing to the last quantifiable measurement. If radioactivity levels were still present at the end of the Study Phase, sampling continued until each sample contained less than 1% of the total radioactive dose. Percentage recovery of 14^C- lenvatinib related material in the urine was summarized as the Geometric Mean (CV%) percent cumulative for all participants and expressed as percent of 14^C- lenvatinib. | Pre-dose, post-dose at 0-6, 6-12, 12-18, 18-24, 24-30, 30-36, 36-42, 42-48, 48-72, 72-96, 96-120, 120-144, and 144-168 hours | 
| Percentage Recovery of 14^C- Lenvatinib Related Material in the Feces | Fecal samples were collected at specific time points, then analyzed for the amount of 14^C- lenvatinib related material. The percentage of the 14^C- lenvatinib dose excreted in feces (Aefeces%) was calculated from time of dosing to the last quantifiable measurement. If radioactivity levels were still present at the end of the Study Phase, sampling continued until each sample contained less than 1% of the total radioactive dose. Percentage recovery of 14^C- lenvatinib related material in the feces was summarized as the Geometric Mean (CV%) percent cumulative for all participants and expressed as percent of 14^C- lenvatinib. | Day 1 to Day 8 |

| Objective Tumor Response | A response of complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD) was assigned by the investigator as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0. CR was defined as disappearance of all target lesions. Any pathological lymph node had to be reduced in short axis to less than 10 mm. PR was defined as at least a 30% decrease in the sum of the longest diameters of target lesions, taking as reference the baseline sum longest diameter. PD was defined as a 20% or greater increase in the sum of the longest diameter of measured lesions, taking as reference the smallest sum longest diameter recorded since treatment start or the appearance of one or more new lesions. CR or PR was confirmed no less than 4 weeks after first observation of the response. For SD, measurements must have met the SD criteria at least once after study entry at a minimum interval of 6 weeks. SD is defined as lasting at least 5 weeks. | Baseline to first date of documented CR, PR, SD, or PD, assessed up to 1 year |
