Study Of Safety, Tolerability And Pharmacokinetics Of Subcutaneous Doses Of TA-46
A SINGLE-CENTER, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, PARALLEL-GROUP STUDY INVESTIGATING THE SAFETY, TOLERABILITY AND PHARMACOKINETICS OF SINGLE- AND MULTIPLE-ASCENDING SUBCUTANEOUS DOSES OF TA-46 IN HEALTHY VOLUNTEERS
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
Study Overview
Detailed Description
This is a single-center, 34-part clinical study in healthy subjects.
Part A This is a single-center, double-blind, randomized, placebo-controlled, single ascending dose study in healthy subjects. The dose escalation is adaptive in nature. An estimated number of 5 dose levels will be administered in Part A of the study, with at each dose level 6 subjects randomized to receive TA-46 and 2 to receive placebo. Depending on evaluation of the data the number of subjects may be adjusted and/or additional group(s) may be added.
In this first-in-human study, the subjects participating at all dose levels of Part A (Groups A1-A5), will be dosed according to a sentinel dosing design to ensure optimal safety. This means that initially 2 subjects will be dosed: 1 subject with TA-46 and 1 subject with placebo. If the safety and tolerability results of the first 24 hours following dosing for the initial subjects are acceptable to the Principal Investigator (PI), the other 6 subjects (5 active and 1 placebo) of that dose level may be dosed.
For Groups A1 and A2, TA-46 and placebo will be administered as a sc injection (bolus) and for Groups A3-A5, TA-46 and placebo will be administered as a sc infusion. When TA-46 and placebo will be administered as sc infusion, the duration of the sc infusion will be dependent on the volume to be administered, but will not exceed a period of 1 hour. The dose levels of TA-46 can be increased or decreased based on the results of the previous group(s).
Part B This is a single-center, double-blind, randomized, placebo-controlled, multiple ascending dose study in healthy subjects. The dose escalation is adaptive in nature. TA-46 will be administered twice weekly for4 weeks. An estimated number of 3 dose levels will be administered in Part B of the study, with at each dose level 6 subjects randomized to receive TA-46 and 2 to receive placebo. Depending on evaluation of the data the number of subjects may be adjusted and/or additional group(s) may be added. Based on the results of Groups B1 and B2 of Part B, which followed a twice weekly dosing scheme for 4 weeks, the dosing scheme of Group B3 will be adapted to once weekly administration for 4 weeks and 31 additional groups (Groups B4 to B6) with the same dosing frequency will be added to Part B of the study. Depending on evaluation of the data, additional group(s) may be added or planned group(s) may be skipped.
For Group B1, TA-46 and placebo will be administered as a sc injection (bolus) and for Groups B2 to B64, TA-46 and placebo will be administered as a sc infusion. When TA-46 and placebo will be administered as a sc infusion, the duration of the sc infusion will be dependent on the volume to be administered, but will not exceed a period of 1 hour. The dose levels of TA-46 can be increased or decreased based on the results of the previous group(s).
Administration of a dose level in Part B can be started after completion and review of the corresponding or higher dose level in Part A of the study.
Part C This is a single-center, single-dose, open-label, cross-over study in healthy subjects comparing 2 formulations of TA-46 (50 mg/mL and 120 mg/mL). A total of 6 subjects will receive Treatment A (TA-46 formulation 1) and Treatment B (TA-46 formulation 2) randomly assigned over 2 periods with 2 treatment sequences (Treatment A/B and Treatment B/A) with 3 subjects per treatment in each sequence.
The following treatments are planned to be administered according to the randomization code:
Group C1 Treatment A: sc administration of 3 mg/kg TA-46 formulation 1 Treatment B: sc administration of 3 mg/kg TA-46 formulation 2TA-46 formulation 1 will be administered as a a sc infusion. The duration of the sc infusion will be dependent on the volume to be administered, but will not exceed a period of 1 hour. TA-46 formulation 2 will be administered as 1-2 sc injection(s) (bolus).
The subjects will be in the clinic for 2 periods. Each period the subjects will be admitted to the clinical research center in the afternoon of Day -1 and 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 6, 9, 12, 16, and 22 of each period.
Part D This is a single-center, open-label, single-dose study in healthy subjects with the TA-46 formulation of 120 mg/mL.
TA-46 and placebo will be administered as a sc infusion. The duration of the sc infusion will be dependent on the volume to be administered, but will not exceed a period of 1 hour. Depending on evaluation of the data, additional group(s) may be added or planned group(s) may be skipped.
