Summary

This is a Phase I, first-in-human study to evaluate the safety and efficacy of the \[68Ga\]Ga DOTA-5G and \[177Lu\]Lu DOTA-ABM-5G theranostic pair in patients with locally advanced or metastatic pancreatic adenocarcinoma (PDAC).

Detailed description

This is a Phase I, first-in-human study to evaluate the safety and efficacy of the \[68Ga\]Ga DOTA-5G /\[177Lu\]Lu DOTA-ABM-5G theranostic pair in patients with locally advanced or metastatic pancreatic ductal adenocarcinoma (PDAC). PET imaging using \[68Ga\]Ga DOTA-5G will be used to diagnose patients who are eligible for the \[177Lu\]Lu DOTA-ABM-5G. The overall purpose of this study is to identify the dose limiting toxicity (DLT) and recommended phase 2 dose (RP2D) of \[177Lu\]Lu DOTA-ABM-5G. A 3+3 study design in is proposed to identify the RP2D of \[177Lu\]Lu DOTA-ABM-5G. An expansion group will receive the RP2D in order to obtain initial estimates of response and additional information on safety of \[177Lu\]Lu DOTA-ABM-5G. The hypotheses of this phase I study are that a) \[68Ga\]Ga DOTA-5G will detect lesions in patients with locally advanced or metastatic pancreas cancer b) the theranostic pair \[68Ga\]Ga DOTA-5G/ \[177Lu\]Lu DOTA-ABM-5G will be safe and well tolerated c) we will be able to identify a Recommended Phase 2 Dose (RP2D) for \[177Lu\]Lu DOTA-ABM-5G therapy to be used in subsequent Phase II trials.
