NCT05706129 | RECRUITING | Clear Cell Renal Cell Cancer (ccRCC)

A Study to Assess Safety, Tolerability and Imaging Characteristics of [68Ga]Ga-DPI-4452 and to Assess Safety, Tolerability, and Efficacy of [177Lu]Lu-DPI-4452 in Participants With Unresectable Locally Advanced or Metastatic Solid Tumors
Sponsor:

ITM Oncologics GmbH

Brief Summary:

The main purpose of Part A of the study is to evaluate safety, tolerability and tracer uptake after a single intravenous (IV) administration of \[68Ga\]Ga-DPI-4452 for each tumor type such as clear cell renal cell cancer (ccRCC), pancreatic ductal adenocarcinoma (PDAC), and colorectal cancer (CRC); Part B: is to determine the recommended phase 2 dose (RP2D) \[maximum tolerated dose (MTD) or lower dose\] for \[177Lu\]Lu-DPI-4452 for each tumor type such as ccRCC, PDAC, CRC, and urothelial carcinoma (UC); Part C: is to evaluate the preliminary antitumor activity of \[177Lu\]Lu-DPI-4452 as monotherapy for each tumor type such as ccRCC, PDAC, CRC, and UC; Part D: is to assess the diagnostic concordance between \[68Ga\]Ga-DPI-4452 Positron Emission Tomography (PET) and the histopathology result of the Indeterminate Renal Mass (IDRM); Part E: is to assess \[68Ga\]Ga-DPI-4452 uptake in each tumour type such as UC, muscle invasive bladder cancer (MIBC), head and neck cancer (H\&N), triple negative breast cancer (TNBC), squamous non-small cell lung cancer (NSCLC), and any other tumor with locally confirmed carbonic anhydrase (CA) IX expression except ccRCC, CRC and PDAC.
