  • Locally advanced unresectable or metastatic PDAC, with disease progression following, or intolerance to cytotoxic therapy, unless patient was ineligible to receive such therapy
  • Locally advanced unresectable or metastatic NSCLC without any actionable genomic alterations with disease progression following, or intolerance to chemotherapy and immunotherapy, unless patient was ineligible to receive such therapy, or locally advanced unresectable or metastatic NSCLC with an actionable genomic alteration with disease progression following, or intolerance to chemotherapy and targeted therapy, unless patient was ineligible to receive such therapy
  • Locally advanced unresectable or metastatic HR+/HER2- ductal and lobular breast cancer with disease progression following, or intolerance to, hormone therapy and CDK inhibitor, and at least one additional line of therapy, unless patient was ineligible to receive such therapy
  • Locally advanced unresectable or metastatic triple negative breast cancer (TNBC) with disease progression following, or intolerance to, at least two lines of therapy, unless patient was ineligible to receive such therapy

Patients with known microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) status must also have had disease progression following, or intolerance to, immune checkpoint inhibitor therapy, unless patient was ineligible to receive such therapy
  • (Dose expansion only) Locally advanced unresectable or metastatic soft tissue sarcoma (excluding GIST and Kaposi) with disease progression following, or intolerance to, at least one line of systemic therapy
  • Patients must have lesions showing 68Ga-NNS309 uptake
Reasons someone may not be able to joinExclusion criteria
  • Absolute neutrophil count (ANC) \< 1.5 x 109/L, hemoglobin \< 9 g/dL, or platelet count \< 100 x 109/L
  • QT interval corrected by Fridericia's formula (QTcF) ≥ 470 msec
  • eGFR \< 60 mL/min/1.73m2, calculated using CKD-EPI 2021 or measured
  • Unmanageable urinary tract obstruction or urinary incontinence
  • Presence of symptomatic CNS metastases, or CNS metastases that require local CNS-directed therapy
  • Any prior radioligand therapy
  • Radiation therapy within 4 weeks prior to the first dose of \[177Lu\]Lu-DFC413 Other protocol-defined inclusion/
