Study Endpoints

Primary Endpoints

Standard uptake values (SUVs) of [68Ga]Ga-DWJ155 in selected organs, normal tissue and tumor lesions
Up to 180 minutes after the end of injection of [68Ga]Ga-DWJ155

Standardized uptake values (SUVs) will be measured in organs of interest, normal tissues, and tumor lesions based on positron emission tomography (PET) imaging.

Standardized uptake value ratio (SUVr) of [68Ga]Ga-DWJ155 in tumor lesions relative to reference organs
Up to 180 minutes after the end of injection of [68Ga]Ga-DWJ155

Standardized uptake value ratios (SUVr) will be calculated as the ratio of SUV in tumor lesions to SUV in normal organs.

Standard Uptake Value (SUV) mean and max of FKL480 uptake in normal organs and tumor lesions over time
Up 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 time
Up 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 Endpoints

Incidence and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs)
Up to 3 days after the administration of [68Ga]Ga-DWJ155
Area under the concentration-time curve (AUC) of blood radioactivity (Imaging characterization part only)
From pre-dose up to 180 minutes after the end of injection of [68Ga]Ga-DWJ155
Maximum observed concentration (Cmax) of blood radioactivity (Imaging characterization part only)
From pre-dose up to 180 minutes after the end of injection of [68Ga]Ga-DWJ155

Frequently asked questions about Ga-DWJ155

What is Ga-DWJ155?

Ga-DWJ155 is an investigational imaging agent being studied in adults with solid tumors, including advanced gastroesophageal adenocarcinoma and breast cancer. It is also written as [68Ga]Ga-DWJ155, reflecting its gallium-68 radiolabel. Novartis AG is developing it, and it is currently in Phase 1 clinical testing.

What is Ga-DWJ155 used for?

Ga-DWJ155 is being studied for use in patients with advanced solid tumors, specifically advanced gastroesophageal adenocarcinoma, breast cancer including triple-negative breast cancer, and non-small cell lung cancer. It is an investigational agent in Phase 1 development and has not been approved for any indication.

Who makes Ga-DWJ155?

Novartis AG, which trades under the ticker NVS, is the developer of Ga-DWJ155. The company is running the Phase 1 clinical program for this investigational agent in patients with advanced solid tumors.

What phase is Ga-DWJ155 in?

Ga-DWJ155 is in Phase 1 clinical development. It is investigational and has not been approved by the FDA or any other regulatory authority. The program consists of early-stage studies designed to evaluate the agent in adults with advanced solid tumors.

What clinical trials is Ga-DWJ155 in?

Ga-DWJ155 is being evaluated in two recruiting Phase 1 trials. NCT07801508 is enrolling 66 adults with solid tumors in Australia and Japan, and NCT07117214 is enrolling 36 adults with breast and lung cancers in the Netherlands. Both studies require participants to be at least 18 years old.

Is Ga-DWJ155 the same as [68Ga]Ga-DWJ155?

Yes, Ga-DWJ155 and [68Ga]Ga-DWJ155 refer to the same investigational agent. The bracketed form is the radiochemical notation that specifies the gallium-68 isotope used in the compound, while Ga-DWJ155 is the shorter name used in company and trial communications.
