Study Endpoints

Primary Endpoints

Occurrence of treatment emergent adverse events (TEAEs), adverse events of special interest (AESIs), treatment emergent serious adverse events (SAEs)
up to 100 days after the last dose of treatment

In the combination treatment regimen according to the (US) National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events version 5.0 (CTCAE version 5.0). By treatment arm and overall.

Occurrence of dose interruption, dose reduction, and discontinuation of study treatment due to adverse events (AEs)
up to 100 days after the last dose of treatment

By treatment arm and overall.

Objective Response Rate (ORR)
Until end-of-treatment visit, i.e., up to 24 months after the first dose of treatment

Defined as the proportion of participants in whom a confirmed complete response (CR) or partial response (PR) (per Response Evaluation Criteria in Solid Tumors version 1.1 \[RECIST 1.1\] based on the investigator's assessment) is observed as best overall response. By treatment arm.

Best percentage change from baseline in the tumor size
Until end-of-treatment visit, i.e., up to 24 months after the first dose of treatment

Based on the investigator's tumor assessment according to RECIST 1.1. Defined as the change from baseline in percent to the minimal tumor size until tumor progression/recurrence or death (whichever occurs first). By treatment arm.

Proportion of participants who have achieved early tumor shrinkage
up to 4 months after first dose of treatment

Defined as ≥10% decrease in the pretreatment sum of diameters at first post-treatment tumor scan in target lesions. By treatment arm.

Occurrence of treatment emergent adverse events (TEAEs), adverse events of special interest (AESIs), treatment-related TEAEs, treatment-related serious adverse events (SAEs) and treatment-related treatment emergent SAEs
up to 100 days after the last dose of treatment

In the combination treatment regimen according to the (US) National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 (NCI CTCAE v5.0). By treatment arm and overall.

Occurrence of dose interruption, reduction, and discontinuation of study treatment due to TEAEs
up to 100 days after the last dose of treatment

By treatment arm and overall.

Objective Response Rate
up to 24 months after completion of study treatment of the last participant

Defined as the proportion of participants in whom a confirmed complete response (CR) or partial response (PR) (per Response Evaluation Criteria in Solid Tumors version 1.1 \[RECIST 1.1\] based on the investigator's assessment) is observed as best overall response. By treatment arm.

Secondary Endpoints

PK assessment: Maximum concentration (Cmax) derived from serum concentration of BNT327
from pre-dose to 15 days after study treatment
PK assessment: Area Under the Curve During the Dosing Interval (AUCtau) derived from serum concentration of BNT327
from pre-dose to 15 days after study treatment
Incidence of detectable BNT327 antidrug antibodies in serum

Frequently asked questions about BNT327 Dose Level 1

What is BNT327 Dose Level 1 used for?

BNT327 Dose Level 1 is an investigational small molecule being studied for extensive-stage small-cell lung cancer and locally advanced breast cancer, including triple negative breast cancer. It is in Phase 2 clinical development and is not yet approved by regulatory authorities.

Who makes BNT327 Dose Level 1?

BNT327 Dose Level 1 is being developed by BioNTech SE, a biotechnology company traded on NASDAQ under the ticker BNTX. The company is conducting Phase 2 clinical trials to evaluate the drug's safety and preliminary effectiveness in oncology indications.

What phase is BNT327 Dose Level 1 in?

BNT327 Dose Level 1 is in Phase 2 clinical development. It is an investigational therapy, meaning it has not been approved by the FDA or other regulatory agencies. The drug is being studied in active but not recruiting clinical trials for lung and breast cancers.

What clinical trials is BNT327 Dose Level 1 in?

BNT327 Dose Level 1 is being evaluated in two Phase 2 trials. NCT06449209 studies the drug with chemotherapy in extensive-stage small-cell lung cancer with 110 participants. NCT06449222 studies it with chemotherapy in locally advanced and metastatic triple negative breast cancer with 83 participants.

Is BNT327 Dose Level 1 the same as BNT327?

BNT327 Dose Level 1 is a specific dose level of the investigational drug BNT327. The clinical trials listed under NCT06449209 and NCT06449222 evaluate BNT327 at this dose level in combination with chemotherapy for lung and breast cancer indications.
