About
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.
Full 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.

Inclusion and exclusion criteria
INCLUSION CRITERIA
EXCLUSION CRITERIA
Participants with brain or subdural metastases, unless they had completed local therapy and have discontinued the use of corticosteroids for this indication for at least 4 weeks before starting treatment in this study. Any signs and/or symptoms of brain metastases those were stable for at least 4 weeks.
Participants with meningeal carcinomatosis
Any of the following values for laboratory parameters:
Uncontrolled infections
Significant cardiovascular impairment (history of congestive heart failure greater than New York Heart Association (NYHA) Class II, unstable ischemic heart disease including a myocardial infarction within six months of study start, or serious cardiac arrhythmia)
Participants with marked baseline prolongation of QT/QT interval corrected for heart rate (QTc) interval (QTc interval greater than or equal to 500 msec) using the Fridericia method
Any treatment with an investigational drug within the last 30 days
Women who were pregnant or breast-feeding; women of childbearing potential with a positive pregnancy test at screening or no pregnancy test. Women of child-bearing potential unless (1) surgically sterile or (2) using adequate measures of contraception in the opinion of the Investigator (including two forms of contraception, one of which must be a barrier method). Perimenopausal women who were amenorrheic for at least 12 months to be considered of non-child-bearing potential. Fertile males with female partners of child-bearing potential who were not willing to use contraception, or whose female partners were not using adequate contraceptive protection, were excluded.
Proteinuria greater than 1+ on bedside testing
History of gastrointestinal malabsorption
Surgery within four weeks of start of study treatment
Bleeding or thrombotic disorders or use of an anticoagulant, such as warfarin, with a therapeutic INR. Aspirin, non-steroidal anti-inflammatory drugs (NSAIDs), and low molecular weight heparin (LMWH) were permissible but when used with caution.
Poorly controlled hypertension (defined as a change in hypertensive therapy within three months of study start) or participants diagnosed with hypertension (defined as a repeat blood pressure measurement of 160/90 mmHg or higher) at screening
Previous lenvatinib therapy
History of alcoholism, drug addiction, psychiatric or psychological condition, or social situation which, in the opinion of the investigator, would impair study compliance
History of allergic reactions attributed to compounds of similar chemical or biological composition to lenvatinib
Other significant disease or disorder that, in the Investigator's opinion, would exclude the participant from the study
