Number of Participants With Treatment Emergent Adverse Events (TEAEs), Serious Adverse Events (SAE) and DeathPrimary· From screening up to Day 90
An adverse event (AE) is defined as any untoward medical occurrence in a patient and which does not necessarily have a causal relationship with the study medication. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease, temporally associated with the use of a study medication, whether or not causally related to the study medication. TEAEs are defined as all AEs reported after the first dose. An SAE is any untoward medical occurrence that at any dose: results in death, is life-threatening, life-threatening, results in persis

Adverse events — posted to ClinicalTrials.gov
Time frame: From start of screening up to Day 90.
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
This was a monocentric, open label, Phase I-IIa study. Eligible patients who signed the ICF received two single intravenous (IV) bolus of the imaging agent 99mTc-rhAnnexin V-128. The first dose was administered on Day 1, and the second dose on Day 42 (±2 weeks).
All patients were to start a new disease modifying treatment for RA or AS on Day 2. This disease modifying treatment was at the discretion of the investigator and was not chosen by the sponsor.
Safety was monitored at every visit. Whole body scintigraphic imaging was performed at Day 1 and Day 42 after 99mTc-rhAnnexin V-128 dosing. Clinical disease assessments were performed at screening, Day 42 and Day 90 to assess response to RA or AS treatment. Blood was drawn to test for 99mTc-rhAnnexin V-128 immunogenicity at screening and on Days 30, 56 and 90. Patients participating in the pharmacokinetic (PK)/dosimetric sub-study had additional assessments in the 24 hours following the Day 1 dose of 99mTc-rhAnnexin V-128.
