Phase 3: testing BNT323/DB-1303 for Endometrial Cancer

The study is divided into two cohorts (Cohort 1 and Cohort 2), to which you would be enrolled based on the amount of human epidermal growth factor receptor 2 (HER2) in their tumor sample. In Cohort 1, the main goal is to assess how well BNT323 (also known as DB-1303) or chemotherapy (doxorubicin or paclitaxel \[or docetaxel, if participants cannot take paclitaxel\]) works by determining the progression-free survival (PFS) of participants who have been previously treated with immune checkpoint inhibitors (ICIs).

Official registry: https://clinicaltrials.gov/study/NCT06340568 · BioNTech SE · enrollment listed as 480

What this phase means

Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.

Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.

What the registry says happens

If you join, the listed intervention(s) are BNT323/DB-1303, Doxorubicin, or Paclitaxel. The registry lists allocation as randomized. The study is divided into two cohorts (Cohort 1 and Cohort 2), to which you would be enrolled based on the amount of human epidermal growth factor receptor 2 (HER2) in their tumor sample.

They plan to enroll about 480 people at 214 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.
