      Background and study aims

      GDC-6036 is an experimental drug being developed for the potential treatment of cancers with particular changes in the genes.

      An experimental drug is a drug that has not been approved by health authorities. The aim of this study is to:

      1. Determine how the study drug is processed by and removed from the body.

      2. Determine how much of the study drug gets into the blood, urine, and stool, and how long it takes the body to get rid of it.

      3. Evaluate the study drug and its breakdown products in blood, urine, stool, and, for some participants, bile (a liquid that is made by the liver, stored in the gallbladder, and aids in digestion).

      4. Evaluate how safe and tolerable the study drug is and collect information regarding its side effects.

      Who can participate?
      Male participants between 18 and 65 years

      What does the study involve?
      Participants will have to be a part of this study for a minimum of 15 days, and up to about 8.5 weeks, not including the screening visit. The study will have three parts:
      first there is a screening period of up to 27 days before dosing wherein participants will undergo various tests to determine if they are eligible to participate in the study. Treatment/confinement: Eligible participants will be admitted to the study site (CRU) on the day prior to GDC-6036 dosing (check-in [Day -1]). During this period all participants will receive a single oral dose of 100 mg [14C]-GDC- 6036 capsule followed by 240 ml of room temperature water on Day 1 under fasted conditions. Participants will remain confined at the study site from the time of check-in (Day -1) until clinic discharge (at least Day 14 [312 hours after study drug administration (postdose)] if certain discharge criteria are met. Participants who do not meet the discharge criteria will have to remain in the study site for up to Day 28 [648 hours postdose]). If by Day 28, discharge criteria have not been met, the subject may be asked to return to the CRU every 7 days thereafter, for up to 4 times.
      Follow-up: All participants will be followed up for any serious adverse events (SAEs), adverse events of special interest (AESIs) and pregnancies after the treatment is finished up to a maximum of Day 57 (±1 day).

      What are the possible benefits and risks of participating?
      Participation in this study is purely for research purposes and will not improve the health or treat any medical problem a participant may have, but the information that is learned may help people with certain kinds of cancers in the future. A participant may benefit by having physical examinations. The results of laboratory tests done at the screening visit will be made available to the participant upon request.
      Participants will receive monetary compensation for participating in this study.
      Participants may have side effects from the drug or procedures used in this study. Side effects can be mild to severe and even life-threatening or fatal, and they can vary from person to person.
      There may be a risk in exposing an unborn child to the study drug, and all risks are not known at this time. Participants must take precautions to avoid exposing an unborn child to the study drug.
      The study drug GDC-6036 has had limited testing in humans.
      Known/potential side effects: Loose stools (diarrhea), nausea, vomiting, fatigue, abnormal liver tests which may indicate liver damage, decreased appetite, headache, stomach pain (abdominal pain), increase in certain secretions of a gland called pancreas indicating pancreatic damage, acid reflux (gastroesophageal reflux disease), upset stomach (dyspepsia), constipation.
      Unknown/Unforeseeable risks: Severe or life-threatening allergic reactions or unexpected interactions with another medication. Symptoms of an allergic reaction may include rash, flushing, itching, sneezing, or runny nose, abdominal pain, diarrhea, swelling of face, tongue or throat, dizziness, lightheadedness or fainting, trouble breathing, irregular or racing heart rate, and seizures.
      The bile samples will be collected using the EnteroTracker® capsule and string device. Participants will have to swallow a gelatin capsule which contains the string within. The end of the string will be taped to the participant's cheek or the back of their neck. The string will be pulled out after a specified period of time. During the string test participants may have an uncomfortable sensation due to the string in the back of their throat. They may also have trouble swallowing the pill. In addition, when the string is pulled back up, they may gag or feel like they want to vomit. The string is very small and thin and will likely not hurt the participant as it comes back up. The study staff will likely remove the string quickly, within a few seconds, which means that any discomfort should not last long. On rare occasions, a mild, superficial lesion caused by the string retrieval may result in some bleeding.
