About this study
Official title: A Phase I Open-label, Multi-center Study to Evaluate the Safety, Tolerability, Dosimetry, and Preliminary Activity of [177Lu]Lu-DWJ155 and Safety and Imaging Properties of [68Ga]Ga-DWJ155 in Patients With Solid Tumors
The purpose of this phase I study is to evaluate the safety, tolerability, dosimetry, and preliminary anti-tumor activity of [177Lu]Lu-DWJ155 and the safety and imaging properties of [68Ga]Ga-DWJ155 in patients with histologically or cytologically confirmed advanced HER2+, HR+/HER2-negative, or triple negative breast cancer (TNBC), non-small cell lung cancer (NSCLC), HER2-3+ or 2+ (ISH positive or negative) gastric/gastroesophageal junction (GEJ) cancer, and bladder cancer.
Read the detailed description
The study will be done in two parts. The first part is called "escalation" and the second part is called "expansion". In both parts of the study, patients will initially be imaged with a [68Ga]Ga-DWJ155 positron emission tomography (PET)/computed tomography (CT) or PET/magnetic resonance imaging (MRI) scan. In the escalation part, different doses of [177Lu]Lu-DWJ155 will then be tested to identify recommended dose(s) (RD(s)) for further evaluation. The expansion part of the study will examine the safety and preliminary efficacy of [177Lu]Lu-DWJ155 at the RD(s) determined during the escalation part.
In both parts, there will be a safety follow-up period after the last [177Lu]Lu-DWJ155 administration.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing [68Ga]Ga-DWJ155 and [177Lu]Lu-DWJ155 in people with Breast Cancer and Non-small Cell Lung Cancer (NSCLC), run by Novartis Pharmaceuticals at 6 sites in 4 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 3 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in United States, Canada, Australia, Japan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Novartis Pharmaceuticals (1-888-669-6682, novartis.email@novartis.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs) of [177Lu]Lu-DWJ155 (time frame: Up to approximately 53 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2026.
