Criteria

Inclusion Criteria:

Part A:

• Healthy subjects

• The subject has a normal structural MRI (sMRI) scan performed in the screening period, as judged by the investigator.

• The subject is, in the opinion of the investigator, generally healthy based on the assessment of medical history, physical examination, vital signs, body weight, ECG, and the results of the haematology, clinical chemistry, urinalysis, serology, and other laboratory tests.

• The subject can tolerate confined spaces for prolonged periods of time.

• The subject is suitable for radial and/or brachial artery blood sampling and cannulation.

Part B:

• Patients with Parkinson's disease

• The subject has a normal sMRI scan performed in the screening period, as judged by the investigator.

• The patient is, in the opinion of the investigator, fit for enrolment in the study based on the assessment of medical history, physical examination, vital signs, body weight, ECG, and the results of the haematology, clinical chemistry, urinalysis, serology, and other laboratory tests.

• The patient has been diagnosed with idiopathic Parkinson's disease for ≥3 years, with a current disease severity of 2 to 4 on the modified Hoehn and Yahr scale in the OFF state.

• The patient has dyskinesia that is not too severe to cause discomfort for the patient during PET imaging and predictable OFF time

• In addition to the above criteria, the patient must, in the opinion of the investigator, also be suitable for the study and the included PET imaging sessions.

• The patient has been receiving a stable regimen of levodopa-containing therapy (total levodopa dose ≤1600 mg per day) (≥3 doses per day of standard levodopa or ≥3 doses per day of carbidopa and levodopa, sustained-release tablets or extended-release capsules of carbidopa and levodopa or benserazide and levodopa), and be on a stable regimen of permitted anti-Parkinsonian drugs (peripheral decarboxylase inhibitors, dopamine agonists [except apomorphine], monoamine oxidase type B [MAO-B] inhibitors [except safinamide], or catechol-O-methyl transferase [COMT] inhibitors) for ≥4 weeks prior to foliglurax dosing

• The patient can tolerate confined spaces for prolonged periods of time

• The patient is suitable for radial and/or brachial artery blood sampling and cannulation

Exclusion Criteria:

• The subject has any concurrent disorder that may affect the particular target or absorption, distribution, or elimination of the IMP

Other inclusion and exclusion criteria may apply.
