Drug: Antibody TF2
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Prospective Multicentric Optimization and Phase I/II Study of Pretargeted Radioimmunotherapy (PRAIT) Using Anti-CEA x Anti-HSG TF2 Bispecific Antibody (bsMAb) and 177Lu-IMP-288 Peptide in Patients With CEA-expressing Small Cell Lung Carcinoma (SCLC) or CEA-expressing Non Small Cell Lung Carcinoma (NSCLC)|
- Primary endpoint of study plan I: To determine the optimal TF2 protein dose for pretargeting IMP-288.
- Primary endpoint of study plan II • the maximum tolerated dose (MTD) for the TF2-pretargeted 177Lu-IMP-288 under optimal pretargeting conditions.

Drug: Antibody TF2
The purpose of this open-label prospective optimization and phase I/II clinical trial is to examine the safety, optimal dose, targeting, dosimetry and efficacy of PRAIT using the humanized anti-CEA x anti-HSG bsMAb TF2 and the 177Lu-IMP-288 peptide pretargeted in patients with CEA-positive SCLC or CEA-expressing Non Small Cell Lung Carcinoma (NSCLC)
This study has 2 parts: Study plan I (Optimization study) and Study plan II (Escalating activity phase I/II study).
The Study plan I is designed to optimize the pretargeting procedure using blood pharmacokinetics (Pk) and dosimetry in 9 patients receiving escalating doses of TF2 followed 2 to 4 days later by 1.1 GBq/m2 of 177Lu-IMP-288.
The study plan II is designed to determined MTD of 177Lu-IMP-288 using dosimetry and toxicity data in a phase I/II study performed in patients receiving optimal dose of TF2 bsMAb (determined in study plan I) followed 2 to 4 days by escalating activity of 177Lu-IMP-288.
A pre-therapy imaging study (using TF2 followed 2 to 4 days later by 185 MBq of 111In-IMP-288) is performed in the two study plans to qualify a patient for treatment with the subsequent therapy dose.
