Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Multiple Rising Oral Doses of BI 1026706 in Male and Female Healthy Subjects and Patients With Osteoarthritis of the Knee

Inclusion criteria

• Males or females without any clinically relevant medical disorders according to the investigator's assessment, as based on the following: a complete medical history including a physical examination, vital signs (blood pressure, pulse rate), 12-lead electrocardiogram, and clinical laboratory tests
• For OA patients: Evidence of OA of the knee by radiography or by magnetic resonance tomography (Kellgren-Lawrence grade 1, 2, or 3; excluding grades 0 and 4) of the knee (tibiofemoral joint only) within the last 5 years consistent with the clinical diagnosis of osteoarthritis of the knee according to American College of Rheumatology (ACR) guidelines
• For OA patients: American Rheumatism Association (ARA) functional class I, II, or III
• For OA patients: Average pain in the index knee over the previous 48 hours greater than or equal to 4 on the 11-item Likert scale at two time points: 1) at screening (if not on analgesic medication) or after 3 days of wash-out of analgesic medication, and 2) in the evening prior to randomisation
• For OA patients: Presence of bothersome OA related pain for most days within the last month prior to screening at the investigator's discretion, or pain requiring analgesic treatment on more than 3 days per week during the last month prior to screening.
• Age 35 to 65 years (inclusive)
• BMI (Body Mass Index) 18.5 to 33 kg/m2 (inclusive)

Exclusion criteria

• Any finding in the medical examination (including Blood Pressure, Pulse Rate or electrocardiogram) deviating from normal and judged clinically relevant by the investigator
• Repeated measurement of systolic blood pressure greater than 140 mm Hg or diastolic blood pressure greater than 90 mm Hg
• Any laboratory value outside the reference range that the investigator considers to be of clinical relevance
• Any evidence of a concomitant disease judged clinically relevant by the investigator
• Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
• Surgery of the gastrointestinal tract that could interfere with kinetics of the study drug(s)
• Diseases of the central nervous system (such as epilepsy), other neurological disorders or psychiatric disorders
