• Use of tobacco, nicotine, or nicotine-replacement products within 30 days prior to Check-in or planned use during the study.
• Use or intend to use any medications/products known to alter drug absorption, metabolism, or elimination processes, including St. John's wort, within 30 days prior to Check-in, unless deemed acceptable by the Investigator (or designee).
• Use/receipt of any prescription or nonprescription medication, herbal products, vitamins or vaccines within 14 days (or 5 half-lives whichever is longer) prior to Check-in, without prior approval from the Medical Monitor.
• Donation of more than 500 mL of blood or plasma within 56 days prior to Check-in, or receipt of a blood transfusion within 1 year prior to Check-in.
• Receipt of any other investigational product or participation in another investigational clinical study that included drug treatment within 30 days, or 5 times the t1/2 of the investigational drug, whichever is longer.
• Have previously completed or withdrawn from this study or any other study investigating TBPM-PI-HBr, and have previously received TBPM-PI-HBr.
• Subjects with exposure to significant diagnostic or therapeutic radiation (e.g., serial X-ray, computed tomography scan, barium meal) or current employment in a job requiring radiation exposure monitoring within 12 months prior to Check-in.
• Subjects who have participated in a radiolabeled drug study where exposures are known to the Investigator within the previous 3 months prior to admission to the clinic for this study or participated in a radiolabeled drug study where exposures are not known to the Investigator within the previous 6 months prior to admission to the clinic for this study. The total 12-month exposure from this study and a maximum of 3 other previous radiolabeled studies within 3 to 12 months prior to this study will be within the CFR recommended levels considered safe, per United States (US) Title 21 CFR 361.1.
