An Ascending Dose Study of PIT565 in Participants With Rheumatoid Arthritis

Prior treatment

• Unstable angina, myocardial infarction, coronary artery bypass graft (CABG), or stroke within 6 months prior to screening
• Concomitant clinically significant cardiac arrhythmias, e.g., sustained ventricular tachycardia, and clinically significant second or third degree atrioventricular block without a pacemaker

Other illness

• Any of the following cardiac conditions
• Clinically significant and/or uncontrolled heart disease such as congestive heart failure requiring treatment (NYHA Grade ≥ 2) or uncontrolled hypertension

Lab values

• History of familial long QT syndrome or known family history of Torsades-de- Pointes
• Use of agents known to prolong the QT interval unless they can be permanently discontinued for the duration of the study.
  • Other protocol-defined inclusion/exclusion criteria may apply.

Other

• Resting QTcF ≥ 450 msec (male) or ≥ 460 msec (female) at screening

• Signed informed consent must be obtained prior to participation in the study. Male and female patients, aged 18 to 75 years at screening, diagnosed with RA according to the 2010 ACR/EULAR or 1987 ACR classification at least 12 weeks prior to screening.
• Immunization (primary or from vaccinations) against pneumococcus, influenza, meningococcus and COVID-19 infection at least 2 weeks prior to the first dosing. Local guidelines should be followed to determine requirement for vaccination (or booster), as well as the type and schedule of vaccination.
