The purpose of this study is to evaluate the pharmacokinetics, in particular the routes of excretion and extent of metabolism of OSI-906 after a single oral dose of 14C-labeled OSI-906. Subjects with Advanced Solid Tumors may participate and then continue into the Optional Treatment Phase.

This study includes two parts: Part A

Subjects will be admitted to the clinical research unit on Day -1 and remain confined to the unit until post dosing discharge criteria are met up to a maximum of 10 days. On Day 1, subjects will receive a single oral dose of 14C-labeled OSI-906.

Part B (optional)

Once the subject has completed part A, the subject may elect to continue participation in Part B. Subjects will receive OSI-906 (non-radiolabeled) twice daily by mouth. Subjects will be seen for scheduled visits every 7 days for the first 36 days and then every 21 days.

• The subject has a negative cotinine test

• If male, is surgically sterile, or is using a medically acceptable method to prevent pregnancy and agrees to continue using this method while participating in the study and for 90 days after the last dose of study medication

• If female, the subject is surgically sterile or status post hysterectomy, post-menopausal, or is using 2 forms of medically acceptable methods of birth control, one of which must be a barrier method to prevent pregnancy and agrees to continue using this method from screening until 90 days after the last dose of study medication

• If female, the subject must not be breastfeeding at Screening, during the study period and for 90 days after last dose of study drug administration

• The subject has an active infection or serious underlying medical condition (including any type of active seizure disorder within 12 months prior to Day 1) that would impair the ability of the subject to receive study drug
• The subject has participated in any interventional clinical study within 21 days or has been treated with any investigational drugs within 30 days or 5 half lives whichever is longer, prior to the initiation of Screening
• The subject has a history of any psychiatric condition that might impair the subject's ability to understand or to comply with the requirements of the study or to provide informed consent
• The subject is pregnant or lactating
