| NCT05192200 | An Extension Study for Participants Who Have Completed the Treatment Period of a Qualifying Parent Study | PHASE2 | COMPLETED | 24 | — | — | Dec 20, 2021 | Nov 20, 2023 | Feb 6, 2025 | 25 | United States, Hungary +2 |
An Adverse Event (AE) was any untoward medical occurrence in a participant or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE was considered treatment emergent relative to a given treatment if the event occurred for the first time during the effective duration of treatment and was not seen prior to the start of treatment, or the event was seen prior to the start of treatment but increased in severity during treatment. AEs included both serious adverse events (SAEs) and all non-SAEs.
Hematology laboratory parameters: hemoglobin (grams per deciliter \[g/dL\]); hematocrit (percentage \[%\]); lymphocytes (10\^3 per (/) millimeter\[mm\]\^3); lymphocytes/leukocytes (%); neutrophils (10\^3/mm\^3) less than (\<)0.8\*lower limit of normal (LLN), leukocytes (10\^3/mm\^3) \<0.6\*LLN, neutrophils (10\^3/mm\^3); basophils (10\^3/mm\^3); basophils/leukocytes (%); monocytes/leukocytes (%); activated partial thromboplastin time (seconds \[sec\]); prothrombin time (sec) more than (\>)1.2\*upper limit of normal (ULN). Clinical chemistry: potassium (milliequivalents per liter \[mEq/L\]); bicarbonate (mEq/L) \<0.9\*LLN, creatine kinase (units per liter \[U/L\]) \>2.0\*ULN, glucose (milligram per deciliter \[mg/dl\]); glucose-fasting (mg/dl) \>1.5\*ULN. Urinalysis: Urine glucose; ketones; urine protein; urine hemoglobin; nitrite; leukocyte esterase; hyaline casts (1/per leukocytosis promoting factor (more than or equal to \[\>=\] 1, urine erythrocytes (scalar); urine leukocytes (scalar) \>=20.
Vital signs included the following parameters: sitting diastolic blood pressure (millimetres of mercury \[mmHg\]) change \>=20 mmHg increase; sitting systolic blood pressure (mmHg) change \>=30 mmHg increase, sitting diastolic blood pressure (mmHg) change \>=20 mmHg decrease and sitting systolic blood pressure (mmHg) change \>=30 mmHg decrease.
ECG parameters evaluated were: PR interval value \>=300 milliseconds (msec); QRS duration value \>=200 msec; QT interval value \>=500 msec; corrected QT Interval using Fridericia's formula (QTCF) 450 less than or equal to (\<=) value \<480 msec, 480 \<=value\<500 msec and value\>=500 msec.
