• Use of transfusion support ≤4 weeks prior to imaging agent administration.
• Treatment with any of the following anti-cancer therapies prior to imaging agent administration within the stated timeframes:
  • Prior treatment with any therapeutic radiopharmaceutical
  • < 10 half-lives for any imaging radiopharmaceutical
  • ≤ 4 weeks for external beam radiation therapy (EBRT) or brachytherapy
  • ≤ 6 months for lung-directed external beam radiotherapy

Más betegség

• Impaired cardiac function or clinically significant cardiac disease.
• Any serious uncontrolled infection (acute or chronic).

Laborértékek

• Out-of-range laboratory values defined as:
  • Creatinine clearance < 60 mL/min (calculated using CKD-EPI 2021 formula, or measured)
  • Total bilirubin > 1.5 x ULN (except for patients with Gilbert's syndrome who are excluded if total bilirubin >3.0 x ULN) or direct bilirubin > 1.5 x ULN
  • Alanine aminotransferase (ALT) > 3 x ULN, except for patients with tumor involvement of the liver who are excluded if ALT > 5 x ULN
  • Aspartate aminotransferase (AST) > 3 x ULN, except for patients with tumor involvement of the liver who are excluded if AST > 5 x ULN
  • Lipase > 1.5 x ULN
  • Absolute neutrophil count (ANC) < 1.5 x 109/L
  • Hemoglobin < 9 g/dL
  • Platelet count < 100 x 109/L

Egyéb

• Unmanageable urinary tract obstruction or urinary incontinence.
• Pregnant or breastfeeding women.
• Patients with non-tumor uptake of [68Ga]Ga-DWJ155 in tissues or organs that, in the opinion of the investigator, increases the risk associated with [177Lu]Lu-DWJ155 treatment.
  • Other protocol-defined inclusion/exclusion criteria may apply.

• Male or female patients age ≥ 18 years.
• Patients with one of the following histologically or cytologically confirmed and documented malignancies who have progressed on or been intolerant to standard of care therapy, and are not considered appropriate for any standard therapy with proven benefit, in the investigator's judgment:
• Dose Escalation:
  • Advanced HER2+ breast cancer with disease progression after at least two prior lines of systemic therapy in the advanced setting
  • Advanced HR+/HER2-low breast cancer with disease progression after prior therapy in the advanced setting
  • Advanced NSCLC without actionable genetic alterations (AGAs) with disease progression after prior therapy in the advanced setting
  • Advanced NSCLC with AGAs who have received prior treatment
  • Measurable disease as determined by RECIST version 1.1.
• Dose Expansion:
  • Advanced HER2+ breast cancer with disease progression after at least two prior lines of systemic therapy in the advanced setting
  • Advanced HR+/HER2-low breast cancer with disease progression after prior therapy in the advanced setting
  • Advanced HR+/HER2 0 breast cancer with disease progression after prior therapy in the advanced setting
  • Advanced HR-/HER2-low breast cancer with disease progression after prior therapy in the advanced setting
  • Advanced HR-/HER2 0 breast cancer with disease progression after prior therapy in the advanced setting
  • Advanced NSCLC with AGAs, who have received prior treatment
  • Advanced NSCLC without known AGAs who have received prior treatment.
  • Advanced gastric/GEJ cancer with HER2 IHC 3+ or 2+ (ISH + or -), following disease progression after prior therapy in the advanced setting
  • Advanced bladder cancer following disease progression after prior therapy in the advanced setting
  • Measurable disease as determined by RECIST version 1.1.
