Phase 2
Completed
Conditions
Hepatic Carcinoma
Interventions
Drug: Ga68-Dolacga Injection
Registration Number
NCT05007548
Lead Sponsor
National Atomic Research Institute, Taiwan
Brief Summary

This is a phase 2 open-labeled study to compare the Ga68-Dolacga positron emission tomography with computer tomography volumetry and indocyanine green retention test for measurement of liver reserve among scheduled surgery operation patients.

Detailed Description

This is a phase 2 open-labeled study to compare the Ga68-Dolacga positron emission tomography with computer tomography volumetry (CTV) and indocyanine green retention test (ICGR15) for measurement of liver reserve among scheduled surgery operation patients. The goal is to enroll 30 eligible subjects scheduled for surgery operation.

CTV and ICGR15 will occur within 7 days prior to the imaging visit for all eligible subjects. During the imaging visit (visit 2, Day 1), subjects will receive an iv bolus injection of 2.0±1.0 mCi Ga68-Dolacga Injection. Ga68-Dolacga PET will be kinetically performed 60 minutes immediately after iv injection.

Two follow-up visits (visit 3 at Day 7±2 and visit 4 at Day 14±2) will be conducted to confirm subject well-being and to collect information about any new adverse events (if any).

Primary Outcome Measures
NameTimeMethod
Measurement of liver reserve obtained from CTV performed in patients scheduled surgical operation (Remnant volume rate (%))within 7 days prior to Day 1

The liver reserve obtained from computer tomography volumetry (CTV) is expressed in "remnant volume rate (%)."

Correlation of the remnant volume rate determined by CTV with conventional liver function testsfrom pre-dose to Day 1

The conventional liver function tests parameters include alanine aminotransferase (U/L), aspartate aminotransferase (U/L), total bilirubin (mg/dL), direct bilirubin (mg/dL), gamma-glutamyl transpeptidase (U/L), total protein (g/dL), albumin/globulin ratio, albumin (g/dL), prothrombin time/International Normalized Ratio (PT/INR), platelet count (×10\^3/μL), ICGR15 (%), Child-Pugh classification (Class A to Class C), MELD score.

Correlation of the ICGR15 with the conventional liver function testsfrom pre-dose to Day 1

The conventional liver function tests parameters include alanine aminotransferase (U/L), aspartate aminotransferase (U/L), total bilirubin (mg/dL), direct bilirubin (mg/dL), gamma-glutamyl transpeptidase (U/L), total protein (g/dL), albumin/globulin ratio, albumin (g/dL), prothrombin time/International Normalized Ratio (PT/INR), platelet count (×10\^3/μL), Child-Pugh classification (Class A to Class C), MELD score.

Measurement of future liver remnant function rate (FLRF%)visit 2 (Day 1)

The future liver remnant function rate (FLRV%) is calculated by dividing the uptake in the future remnant liver volume by the uptake in the total liver volume from Ga68-Dolacga PET and expressed as %.

Measurement of future liver remnant volume rate (FLRV%)within 7 days prior to Day 1

The future liver remnant volume rate (FLRV%) is calculated by dividing the future remnant liver volume by the total functional liver volume from CTV and expressed as %.

Measurement of liver reserve obtained from Ga68-Dolacga PET performed in patients scheduled surgical operation (Percentage of injection dose, %ID)visit 2 (Day 1)

The liver reserve obtained from Ga68-Dolacga PET is expressed in "percentage of injection dose (%ID)."

Correlation of the percentage of injection dose (%ID) in liver determined by Ga68-Dolacga PET with conventional liver function testsfrom pre-dose to Day 1

The conventional liver function tests parameters include alanine aminotransferase (U/L), aspartate aminotransferase (U/L), total bilirubin (mg/dL), direct bilirubin (mg/dL), gamma-glutamyl transpeptidase (U/L), total protein (g/dL), albumin/globulin ratio, albumin (g/dL), prothrombin time/International Normalized Ratio (PT/INR), platelet count (×10\^3/μL), ICGR15 (%), Child-Pugh classification (Class A to Class C), MELD score.

Secondary Outcome Measures
NameTimeMethod
Correlation of the ICGR15 with the fibrosis indicesfrom pre-dose to Day 1

The fibrosis indices include liver stiffness measurement (kPa) determined by Fibroscan and the Fibrosis-4 (FIB-4) index.

Number of subjects with body temperature abnormalitiesfrom pre-dose to 14±2 days post dose
Number of subjects with clinically significant changes in Heart Ratefrom pre-dose to 14±2 days post dose
Comparison of CTV and Ga68-Dolacga PET parameters in patients with PHLFon or after postoperative day 5 (POD 5)

Following parameters will be compared:

* liver reserve obtained from CTV vs liver reserve obtained from Ga68-Dolacga PET

* FLRV% vs FLRF%

Number of subjects reporting clinically significant changes in serum biochemical testsfrom pre-dose to 14±2 days post dose
Number of subjects reporting clinically significant changes in hematological testsfrom pre-dose to 14±2 days post dose
Incidence of posthepatectomy liver failure (PHLF)on or after postoperative day 5 (POD 5)
Number of subjects reporting clinically significant changes in urinalysisfrom pre-dose to 14±2 days post dose

The ECG parameters include: PR interval (milliseconds), QTc interval (milliseconds), QRS duration (milliseconds)

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.

Severity grading of PHLF as defined by the International Study Group of Liver Surgery (ISGLS)on or after postoperative day 5 (POD 5)

Subjects diagnosed with PHLF are classified as grade A, grade B or grade C based on its severity.
