No findings were extractable from the material analysed.
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
The source did not state who this applies to in practice.
Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Registry record from ClinicalTrials.gov (NCT07660055). This is a study registration, not published results. Lead sponsor: Novartis Pharmaceuticals. Recruitment status: RECRUITING. Phase: PHASE1. Study type: INTERVENTIONAL. Enrollment: 156 participants (ESTIMATED). Conditions: Breast Cancer, Non-small Cell Lung Cancer (NSCLC), Gastric/Gastroesophageal Junction (GEJ) Cancer, Bladder Cancer. Interventions: DIAGNOSTIC_TEST: [68Ga]Ga-DWJ155; DRUG: [177Lu]Lu-DWJ155. Primary outcome measures: Incidence and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs) of [177Lu]Lu-DWJ155 , Up to approximately 53 months; Incidence of dose-limiting toxicities (DLTs) of [177Lu]Lu-DWJ155 , Up to 6 weeks; Frequency of dose interruptions and reductions [177Lu]Lu-DWJ155 , 11 months; Dose intensity [177Lu]Lu-DWJ155 , 11 months. Brief summary: 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.
