to Assess the Safety of Ga68-Dolacga Injection in Healthy Volunteers

Phase 1

Completed

• Conditions: Safety Issues
• Interventions: Drug: Ga68-Dolacga Injection

• Registration Number: NCT03908957
• Lead Sponsor: National Atomic Research Institute, Taiwan

Brief Summary

This is a phase 1 study to evaluate the safety of Ga68-Dolacga Injection in healthy volunteers and to assess the normal reference range and inter-individual variability of the Ga68-Dolacga Injection in estimating liver reserve in healthy volunteers.

Detailed Description

Ga-68 is a positron-emitting radionuclide with short half-life of 68 minutes. Dolacga is a non-radiolabeled formulated drug product and will be reconstituted to become the finished radiopharmaceutical product Ga68-Dolacga Injection, a PET tracer specifically targeting to surface receptors of hepatocytes. The study aims to evaluate the safety of Ga68-Dolacga Injection in healthy volunteers and to assess the normal reference range and inter-individual variability of the Ga68-Dolacga Injection in estimating liver reserve in healthy volunteers.

Arm && Interventions

Group	Intervention	Description
Ga68-Dolacga Injection	Ga68-Dolacga Injection	The healthy volunteer was injected with Ga68-Dolacga Injection iv and performed PET imaging for liver reserve evaluation.

Primary Outcome Measures

Name	Time	Method
Number of subjects reporting clinically significant changes in serum biochemical tests	from pre-dose to 14±2 days post dose
Number of subjects reporting clinically significant changes in hematological tests	from pre-dose to 14±2 days post dose
Number of subjects reporting clinically significant changes in urinalysis	from pre-dose to 14±2 days post dose
Number of subjects with body temperature abnormalities	from pre-dose to 14±2 days post dose
Abnormalities of physical examination in visit 2 (post-treatment) compared with visit 1	visit 2 (Day 1)	Including the examination of general appearance, skin, neck (including thyroid), eyes, ears, nose, throat, lungs, heart, abdomen, back, lymph nodes, extremities, vascular and neurological
Incidence of Adverse Events (AEs) and Serious Adverse Events (SAEs)	14 days	All laboratory abnormalities which are compared with screening values and out of the reference range will be considered as AE and will be assessed its relationship to the study drug. Any ECG changes including ECG waveform will be assessed as AE(s) and will be followed to assess whether they resolved and when they resolved.
Number of subjects with clinically significant changes in systolic blood pressure and diastolic blood pressure	from pre-dose to 14±2 days post dose
Number of subjects with clinically significant changes in Heart Rate	from pre-dose to 14±2 days post dose
Number of subjects with clinically significant changes in electrocardiogram(ECG)	from pre-dose to 14±2 days post dose	The ECG parameters include: PR interval (milliseconds), QTc interval (milliseconds), QRS duration (milliseconds)

Secondary Outcome Measures

Name	Time	Method
Establishment of the normal reference range of the percent of injection dose (%ID) in healthy liver	up to 60 minutes after administration of Ga68-Dolacga Injection	The normal reference range will be measured by the mean +/- standard deviation of the liver %ID of all of the phase 1 volunteers.
