Study Description

Brief Summary:

This is an open-label study being conducted to determine the metabolism and physiological disposition of radiolabeled LY2603618 after a single dose in patients with advanced and/or metastatic solid tumors.

Outcome Measures

Primary Outcome Measures :

1. Urinary and Fecal Excretion of LY2603618 Radioactivity Over Time Expressed as a Percentage of the Total Radioactive Dose Administered [ Time Frame: 0 to 6 hours, 6 to 12, 12 to 24, 24 to 48, 48 to 72 and 72 to 96 hours post-dose ]
   Urinary and fecal excretion samples from each participant were measured by liquid scintillation counting. The radioactive counts detected in urine and fecal samples were each divided by the theoretical radioactive count in the total radioactive dose administered and multiplied by 100% to arrive at a percentage of total radioactive dose excreted in urine and feces.

Secondary Outcome Measures :

1. Plasma Pharmacokinetics of LY2603618: Maximum Observed Drug Concentration (Cmax) [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours post-dose ]
   Plasma LY2603618 Cmax following a single dose on Day 1.
2. Plasma Pharmacokinetics of Radioactivity: Maximum Observed Drug Concentration (Cmax) [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours post-dose ]
   Plasma radioactivity Cmax [nanogram equivalents per milliliter (ng Eq/mL)] following a single dose on Day 1.
3. Plasma Pharmacokinetics of LY2603618: Area Under the Concentration Time Curve From Time Zero to Infinity [AUC(0-infinity)] [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours post-dose ]
   Plasma LY2603618 AUC(0-infinity) following a single dose on Day 1.
4. Plasma Pharmacokinetics of Radioactivity: Area Under the Concentration Time Curve From Time Zero to Infinity [AUC(0-infinity)] [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours post-dose ]
   Plasma radioactivity AUC(0-infinity) [nanogram equivalents*hours per milliliter (ng Eq*h/mL)] following a single dose on Day 1.
5. Plasma Pharmacokinetics of LY2603618: Area Under the Concentration Time Curve From Time Zero to Time t [AUC(0-tlast)] [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours post-dose ]
   Plasma LY2603618 AUC(0-tlast) where tlast is the last time point with a measurable concentration following a single dose on Day 1.
6. Plasma Pharmacokinetics of Radioactivity: Area Under the Concentration Time Curve From Time Zero to Time t [AUC(0-tlast)] [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 12, 24, 48, 72 and 96 hours post-dose ]
   Plasma radioactivity AUC(0-tlast) [nanogram equivalents*hours per milliliter (ng Eq*h/mL)] where tlast is the last time point with a measurable concentration following a single dose on Day 1.
7. Relative Abundance of LY2603618 and the Metabolites of LY2603618 in Urine [ Time Frame: Day 1 through 7 days postdose ]
   Relative abundance was expressed as the percentage of the dose of study drug administered and calculated as %=[amount of LY2603618 or its metabolites excreted/amount of radioactive dose administered]*100.
8. Relative Abundance of LY2603618 and the Metabolites of LY2603618 in Feces [ Time Frame: Day 1 through 7 days postdose ]
   Relative abundance was expressed as the percentage of the dose of study drug administered and calculated as %=[amount of LY2603618 or its metabolites excreted/amount of radioactive dose administered]*100.
9. The Number of Participants With a Tumor Response [ Time Frame: Baseline through study completion [Cycle 5 (28 days/cycle) and 21-day safety follow-up] ]
   Tumor responses were followed and measured according to Response Evaluation Criteria In Solid Tumors (RECIST) criteria. Complete response was defined as the disappearance of all target and non-target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 millimeter (mm) and normalization of tumor marker level of non-target lesions. Partial response was defined as at least a 30% decrease in sum of longest diameter of target lesions. Progressive disease was defined as at least 20% increase in sum of longest diameter of target lesions and minimum 5 mm increase over nadir; Stable disease was defined as small changes that did not meet above criteria.

• Are reliable and willing to make themselves available for the duration of the study and are willing to follow study procedure
• Males and females with reproductive potential: Must agree to use medically approved contraceptive precautions during the study and following the last dose of study drug until, in the judgment of the investigator, it is safe for the participant to become pregnant or father a child

• Have an estimated life expectancy that, in the judgment of the investigator, will permit the participant to complete 1 full cycle of treatment (beyond the initial [^14C]LY2603618 dose)
• Prior radiation therapy for treatment of cancer other than pancreatic is allowed to <25% of the bone marrow and participants must have recovered from the acute toxic effects of their treatment prior to study enrollment. Prior radiation to the whole pelvis is not allowed. Prior radiotherapy must be completed at least 4 weeks before study entry.

Exclusion Criteria:

• Have received treatment within 28 days of the initial dose of study drug with an experimental agent for noncancer indications that has not received regulatory approval for any indication

• Have a known allergy to gemcitabine, pemetrexed, LY2603618, or any ingredient of gemcitabine, pemetrexed, or LY2603618 (like Captisol)
• Have serious preexisting medical conditions (left to the discretion of the investigator) other than advanced cancer
• Have symptomatic central nervous system (CNS) malignancy or metastasis (screening not required). Participants with treated CNS metastases are eligible for this study if they are not currently receiving corticosteroids and/or anticonvulsants, and their disease is asymptomatic and radiographically stable for at least 90 days

• Have an active fungal, bacterial, and/or known viral infection including human immunodeficiency virus (HIV) or viral (A, B, or C) hepatitis (screening is not required)
• Have a QTc interval of >500 milliseconds (msec) on the screening electrocardiogram (ECG)
• Have ECG abnormalities on the screening ECG such as significant conduction abnormalities, ischemic changes (such as prior Q-wave myocardial infarction and/or marked ischemic ST- and T-wave), arrhythmias (such as persistent or paroxysmal ventricular or supraventricular arrhythmias, including atrial fibrillation), or other ECG abnormalities that would put the participant at unnecessary risk in the opinion of the investigator
• Have participated in a ^14C study within the last 6 months prior to screening for this study. The total exposure from this study and the previous study must be less than 5 milliSieverts (mSv).
