NCT04410809

Brief Summary

TA-46 single- and multiple-ascending dose study in healthy volunteers to investigate safety and PK. The protocol is conducted in four parts; Part A - Single Ascending doses of TA46 Part B - Multiple Ascending doses of TA-46 Part C - Comparing 2 formulations 50mg/ml vs 120mg/ml TA-46 Part D - Single Ascending dose of TA46 120mg/ml formulation The subjects will be in the clinic for 1 period. The subjects will be admitted to the clinical research center in the afternoon of Day -1. They will be discharged on Day 4 (72 hours post-dose) after completion of the assessments. After discharge, the subjects will return to the clinical research center for ambulatory visits on Days 5, 8, 10, 12, 14 and 22

Outcome Measures

Primary Outcomes (5)

  • Number of Participants With Treatment Emergent Treatment-Related Adverse Events (AEs)

    Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to Y days after last dose that were absent before treatment or that worsened relative to pretreatment state. Relatedness to Drug X was assessed by the investigator (Yes/No). Participants with multiple occurrences of an AE within a category were counted once within the category.

    Bsseline to Day 43 after last dose of study medication

  • Number of Participants With Clinical Laboratory Abnormalities

    Following parameters were analyzed for laboratory examination: hematology (hemoglobin, hematocrit, red blood cell count, platelet count, white blood cell count, total neutrophils, eosinophils, monocytes, basophils, lymphocytes); liver function (aspartate aminotransferase, alanine aminotransferase, total bilirubin, lactate dehydrogenase, alkaline phosphatase, albumin, total protein); renal function (blood urea nitrogen, creatinine, uric acid); electrolytes (sodium, potassium, chloride, calcium, phosphate, bicarbonate); clinical chemistry (glucose, creatine kinase); immunology (CRP); urinalysis (dipstick \[urine specific gravity, decimal logarithm of reciprocal of hydrogen ion activity {pH} of urine, glucose, protein, blood, ketones, bilirubin\], microscopy \[urine RBC, WBC, urate crystals, calcium, oxalate, miscellaneous \[urine mucus and leucocytes\]).

    Baseline up to Day 43 after last dose of study medication

  • Incidence of Anti-Drug Antibody (ADA)

    The percentage of participants with positive ADA and neutralizing antibodies will be summarized for each treatment arm.

    Baselin up to Day 43 after last dose of study medication

  • Number of Participants With Change From Baseline in Physical Examinations and Vital Signs

    Number of participants with potentially clinically important (PCI) physical examinations and vital signs is reported during therapy and at post therapy. Criteria for PCI change in vital signs: heart rate value of \<40 beats per minute and value \>150 beats per minute, systolic blood pressure (SBP) of \<80 or \>210 millimeter of mercury (mmHg), diastolic blood pressure (DBP) of \<40 or \>130 mmHg, temperature \<32 or \>40 degree centigrade, respiratory rate of \<10 or \>50 breaths/minute and criteria for PCI change in physical examination: \>=10% increase or decrease of body weight in kilogram (kg).

    Baseline up to Day 43 after last dose study medication

  • Number of Participants With Abnormal Electrocardiogram (ECG)

    Criteria for ECG abnormalities: maximum PR interval \>=300 milliseconds (msec) and maximum increase PR interval increase from baseline (IFB): percent change (Pctchg) \>=25 percent (%) for baseline value of \>200 msec and Pctchg\>=50% for baseline value of \<=200 msec for PR interval, maximum QRS interval \>=140 msec and a maximum IFB: Pctchg\>=50%, maximum QTCF interval (Fridericia's Correction) of 450 msec to \<480 msec, 480 msec to \<500 msec or \>=500 msec and a maximum change of \<=30change\<60 or \>=60 msec from baseline.

    Baseline up to Day 22 after last dose of study medication
