Interventions
Drug: [68Ga]Ga-DWJ155
Registration Number
NCT07117214
Lead Sponsor
Novartis Pharmaceuticals
Brief Summary

This is a phase I, open label first in human study to evaluate the imaging performance, safety, biodistribution and pharmacokinetics of \[68Ga\]Ga-DWJ155 in patients ≥ 18 years of age with hormone receptor positive/HER2 negative (HR+/HER2-) and HER2 positive (HER2+) advanced breast cancer (aBC) and advanced Non-Small Cell Lung Cancer (aNSCLC) adenocarcinoma.

Detailed Description

This is a first-in-human (FIH), open-label, phase I radioligand imaging study designed to assess the biodistribution, imaging, safety, PK and dosimetry properties in patients with aBC and aNSCLC adenocarcinoma.

Approximately 15-21 aBC and 9-15 aNSCLC patients will be enrolled into the study. All patients enrolled in the study will receive a single administered radioactive dose of FKL480. The study will consist of an imaging characterization part and an expansion part.

Advanced breast cancer[68Ga]Ga-DWJ155Patients will receive FKL480 (\[68Ga\]Ga-DWJ155)
Advanced NSCLC[68Ga]Ga-DWJ155Patients will receive FKL480 (\[68Ga\]Ga-DWJ155)
Primary Outcome Measures
NameTimeMethod
Standard Uptake Value (SUV) mean and max of FKL480 uptake in normal organs and tumor lesions over timeUp to 240 minutes after dosing on Day 1

Imaging properties of FKL480 will be evaluated by assessing radiotracer uptake, identified via positron emission tomography (PET) scans. The SUVmean and SUVmax will be calculated and reported with summary statistics.

Standard Uptake Value ratio (SUVr) of FKL480 uptake in normal organs and tumor lesions over timeUp to 240 minutes after dosing on Day 1

SUVr will be calculated by dividing the SUV of the lesions by the SUV of the different organs in order to identify the reference organ with the lowest uptake and the respective SUVr (i.e. using SUVmean or SUVmax).

Secondary Outcome Measures
NameTimeMethod
Incidence and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs)Up to 3 days after single dose administration on Day 1

Incidence and severity of AEs and SAEs, including changes in vital signs and laboratory values qualifying and reported as AEs.

Dosimetry sub-group: Observed maximum concentration (Cmax) of FKL480 based on blood radioactivity dataUp to 240 minutes after dosing on Day 1

The FKL480 pharmacokinetic analysis will be performed based on blood radioactivity concentration data, obtained by measuring in gamma-counting equipment the blood samples.

Dosimetry sub-group: Urinary excretion of FKL480Up to 240 minutes after dosing on Day 1

The elimination of the compound in urine will be evaluated based on urine radioactivity concentration data obtained by measuring in gamma counting equipment the urine samples.

Dosimetry sub-group: Observed area under the curve (AUC) from time zero to the last measurable concentration sampling time (AUClast) of FKL480 based on blood radioactivity dataUp to 240 minutes after dosing on Day 1

The FKL480 pharmacokinetic analysis will be performed based on blood radioactivity concentration data, obtained by measuring in gamma-counting equipment the blood samples

Dosimetry sub-group: Observed time to reach maximum (Tmax) after single dose administration of FKL480 based on blood radioactivity dataUp to 240 minutes after dosing on Day 1

The FKL480 pharmacokinetic analysis will be performed based on blood radioactivity concentration data, obtained by measuring in gamma-counting equipment the blood samples

Dosimetry sub-group: Absorbed radiation dose in normal tissues and total bodyUp to 240 minutes after dosing on Day 1

Absorbed radiation dose coefficients in selected organs and lesions and total body as measured by image quantification.

Dosimetry sub-group: Effective doseUp to 240 minutes after dosing on Day 1

Effective dose in selected organs and total body as measured by image quantification.
