Plain English summary of protocol

Background and study aims
The Sponsor is developing the test medicine, CORT125329, for the potential treatment of antipsychotic-induced weight gain (AIWG). AIWG is the condition in which patients taking antipsychotic medications have a tendency to gain weight. In addition, antipsychotic drugs can increase the risk of patients developing cardiovascular disease (diseases of the heart/blood vessels). This study will aim to look at how the test medicine is taken up, broken down and removed by the body when given orally as capsules after food. To help investigate this, the test medicine will be radiolabelled. ‘Radiolabelled’ means that the test medicine has a radioactive component, in this case Carbon-14 which is a type of naturally occurring radioactivity. The safety and tolerability of this test medicine will also be studied.

Who can participate?
Healthy male volunteers aged between 45 and 70 years

What does the study involve?
Participants will be admitted to the clinic the evening before the day of dosing. On Day 1, after eating a standard breakfast, participants will receive a single 1200 mg dose of the radiolabelled test medicine as 12 x 100 mg capsules. Their blood, urine and faeces will be taken throughout the study for analysis of the test medicine and its breakdown products, and for their safety. A cerebrospinal fluid (CSF) sample will be taken on one occasion. Participants will remain in the clinic up to Day 11, but if the relevant radioactivity elimination criteria have been met for all participants before Day 11, they may be discharged early as a group. If the relevant criteria have not been met by Day 11, participants may remain in the clinic (up to Day 13). Home collection of urine and/or faeces may be required. Participants are expected to be involved in this study for about6 weeks from screening to the follow-up phone call.

What are the possible benefits and risks of participating?
Participants will get no medical benefit from taking part in this study. It is hoped that the development of a product to improve the treatment of antipsychotic-induced weight gain will be of benefit to patients with this condition. As this is a Phase I study, the most relevant population is healthy volunteers. It is considered that the risk/benefit evaluation in this study supports the use of healthy volunteers. There is always a risk that the stipend in healthy volunteer studies could represent coercion. The time spent in the clinic, travel, inconvenience and other expenses factor in calculating the stipend. Perception of risk is not considered in this calculation. When investigating new medicines there is always a risk of unexpected side effects and occasionally allergic reactions. Participants will be closely monitored during the study. Participants may experience side effects from the test medicine in this study. Full information on possible side effects is provided in the Participant Information Sheet and Informed Consent Form (PIS/ICF). There will be an extended period of fasting for the participants. To ensure an adequate fluid intake, the subjects will be allowed fluids and will be monitored for signs of dehydration and fatigue. Blood samples will be collected during the study, which can cause soreness and bruising of the arm, but these problems usually clear up within a few days to weeks. ECG stickers on subjects' chests and limbs may cause some local irritation and may be uncomfortable to remove. Participants will be closely monitored and if any irritation occurs, appropriate care will be given. CSF samples will be collected. Collection of CSF will be via a lumbar puncture, which may cause some side effects, the most common ones being headaches and swelling/back pain around where the needle was inserted. These are usually mild and should get better after a few days. In some cases they can last for up to a week. The lumbar puncture will be carried out by a consultant anaesthetist. By taking part in the study the participants will be exposed to a small amount of radiation. Further information can be found in the PIS/ICF.

Scientific titleAn open label, single-dose, single-period study designed to assess the mass balance recovery, metabolite profile and metabolite identification of [14C]-CORT125329 in healthy male subjects
Study acronymQSC206122
Study objectivesThe study is not hypothesis testing. The objectives are as follows:

Primary objectives:
1. To determine the mass balance recovery (amount of radioactivity recovered from urine and faeces) after a single oral dose of [14C]-CORT125329
2. To perform metabolite (breakdown product) profiling and structural identification from plasma, urine and faecal samples

Secondary objectives:
1. To determine the routes and rates of elimination of [14C]-CORT125329
2. To identify significant metabolites of CORT125329
3. To explore the oral pharmacokinetics (what the body does to the test medicine, PK) of CORT125329 further
4. To evaluate the extent of distribution of TR (total radioactivity) into blood cells
5. To provide additional safety and tolerability information for CORT125329
6. To determine if CORT125329 crosses the blood-brain barrier

Health condition(s) or problem(s) studiedAntipsychotic-induced weight gain (AIWG)
InterventionThis is a non-randomized, open-label, uncontrolled, single-dose trial. This trial consists of a single study period involving up to 6 healthy male subjects, aged between 45 and 70 years. Following consumption of a standard breakfast, subjects will receive a single oral 1200 mg dose of the radiolabelled test medicine as 12 x 100 mg capsules. Subjects will remain in the clinic up to Day 11, they may be discharged early as a group if the relevant criteria have been met. If the relevant criteria have not been met by Day 11, subjects may remain in the clinic (up to Day 13). Home collections of urine and/or faeces may be required. A follow-up phone call will take place 5 to 8 days after the final collection period to ensure the ongoing wellbeing of the subjects. Subjects are expected to be involved in this study for approximately 6 weeks from screening to follow-up phone call.
