Drug: TD-1473 oral capsule
Drug: [14C]-TD-1473 Oral Capsule

Brief Summary

This is an open-label, 2-cohort study to evaluate the absolute bioavailability, absorption, distribution, metabolism and excretion of TD-1473 in healthy male subjects. Subjects in cohort 1 will receive a single oral dose of TD-1473 and a single intravenous bolus dose of \[14C\]-TD-1473. Subjects in cohort 2 will receive a single oral dose of \[14C\]-TD-1473 only.

  • Subject has a known hypersensitivity towards medications similar to TD 1473 or excipients contained in TD 1473
  • Subject regularly works with ionizing radiation or radioactive material
  • Subject has been exposed to ionizing radiations, within 1 year prior to the start of the study, as external irradiation (i.e., radiological examination including CT scan, excluding dental radiography) or internal radiation (i.e., diagnostic nuclear medicine procedure) or have participated in a radiolabeled study in the last 12 months
  • Subject, who, for any reason, is deemed by the PI or designee or Sponsor to be inappropriate for this study or have any condition which would confound or interfere with the evaluation of the safety, tolerability, and PK of the investigational drug or prevent compliance with the study protocol
