Brief Summary:
The goal of this clinical study is to assess the efficacy of BNT323/DB-1303 compared with investigator's choice of chemotherapy in terms of progression-free survival (PFS) by blinded independent central review (BICR) in the endometrial cancer population with prior immune checkpoint inhibitor (ICI) treatment.
Detailed Description:
This is an open-label, randomized, multi-site, Phase III, interventional clinical study designed to determine the efficacy and safety of BNT323/DB-1303 compared with investigator's choice of single agent chemotherapy in previously treated participants with recurrent endometrial cancer, whose disease has progressed on at least one line of platinum-based therapy.
Participants will be randomized 2:1 to receive either BNT323/DB-1303 or investigator's choice of single agent chemotherapy (doxorubicin or paclitaxel) until Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) defined progressive disease (PD) unless there is unacceptable toxicity, withdrawal of consent, or another criterion for discontinuation is met. Randomization will be stratified by HER2 expression (immunohistochemistry score 1+ vs 2+ vs 3+), number of prior lines of therapy (1 vs 2+), and prior ICI treatment (yes vs no).
The study consists of a two-part screening period (Part 1 \[tissue screening\] and Part 2 \[screening\]) a treatment period, a safety follow-up period, an efficacy follow-up period, and a long-term survival follow-up. The expected treatment duration per participant is \~6 months, followed by an anticipated long-term survival follow-up period of up to 55 months.
