Phase I Study of [177Lu]Lu-NNS309 in Patients With Pancreatic, Lung, Breast and Colorectal Cancers
Trial Status: active
The purpose of this study is to evaluate the safety, tolerability, dosimetry and
preliminary efficacy of [177Lu]Lu-NNS309 and the safety and imaging properties of
[68Ga]Ga-NNS309 in patients aged ≥ 18 years with locally advanced or metastatic
pancreatic ductal adenocarcinoma (PDAC), non-small cell lung cancer (NSCLC), HR+/HER2-
ductal and lobular breast cancer (BC), triple negative breast cancer (TNBC) and
colorectal cancer (CRC).
Inclusion Criteria
Age ≥ 18 years old
Patients with one of the following indications:
Locally advanced unresectable or metastatic PDAC with disease progression following, or intolerance to cytotoxic chemotherapy, 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 targeted therapy, unless patient was ineligible to receive such therapy
Locally advanced unresectable or metastatic HR+/HER2- ductal or lobular BC with disease progression following, or intolerance to, at least 2 lines of therapy, unless patient was ineligible to receive such therapy
Locally advanced unresectable or metastatic TNBC with disease progression following, or intolerance to, at least 2 lines of therapy, unless patient was ineligible to receive such therapy
(Dose escalation part only) Locally advanced or metastatic unresectable CRC with disease progression following, or intolerance to cytotoxic chemotherapy, 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
Patients must have lesions showing 68Ga-NNS309 uptake

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
Creatinine clearance < 60 mL/min
