Brief Summary

This is a Phase II, multi-site, open-label, parallel group study in participants with untreated extended-stage small-cell lung cancer (ES-SCLC) (Cohort 1) or small-cell lung cancer (SCLC) which has progressed on first- or second-line treatment (Cohort 2 and Cohort 3). This study will assess the safety, efficacy, and pharmacokinetics (PK) of BNT327.

Detailed Description

In Cohort 1 of this study, two dose levels of BNT327 will be studied in combination with etoposide and carboplatin to identify an optimized dose for future clinical investigation.

Cohort 2 and Cohort 3 will explore the combination of two dose levels of BNT327 with paclitaxel, or topotecan in the second- or third-line setting.

Patients will be treated until disease progression, intolerable toxicity, patient withdrawal, study termination or up to 2 years (whichever occurs first).

Participants will be assigned to either Cohort 1 or Cohort 2/Cohort 3 based on their disease type (i.e., untreated ES-SCLC for Cohort 1 and SCLC which has progressed on first- or second-line treatment for Cohort 2 and Cohort 3). Assignment to either Cohort 2 or Cohort 3 will be the investigator's choice.

Participants will be randomized to each arm within each cohort:

* Participants enrolled to Cohort 1 and Cohort 3 will be randomized in a 1:1 ratio to Arm 1 or Arm 2.

* Participants enrolled to Cohort 2 will be randomized in a 2:1 ratio to Arm 1 or Arm 2.

Primary Outcome Measures
NameTimeMethod
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 SAEsup 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 TEAEsup to 100 days after the last dose of treatment

By treatment arm and overall.

Objective Response Rateup 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.

Best percentage change from baseline in the tumor sizeup to 24 months after completion of study treatment of the last participant

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 comes first). By treatment arm.

Proportion of participants who have achieved early tumor shrinkageup to 2 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.

Secondary Outcome Measures
NameTimeMethod
PK assessment: Maximum concentration (Cmax) derived from serum concentration of investigational medicinal product (IMP)from pre-dose to 21 days after study treatment

By treatment arm. Only for the first cycle.

PK assessment: Area under the curve during the dosing interval (AUCtau) values derived from serum concentration of IMPfrom pre-dose to 21 days after study treatment

By treatment arm. Only for the first cycle.

Incidence of detectable BNT327 antidrug antibodies in serumfrom pre-dose to 100 days after last dose of study treatment

By treatment arm and overall.

Duration of Responseup to 24 months after completion of study treatment of the last participant

Defined as the time from first objective response (CR or PR per RECIST 1.1) to first occurrence of objective tumor progression or death from any cause, whichever occurs first based on investigator's review.

Disease Control Rateup to 24 months after completion of study treatment of the last participant

Defined as the proportion of participants in whom a confirmed CR or PR or stable disease (per RECIST 1.1, stable disease assessed at least 6 weeks after first dose) is observed as best overall response based on the investigator's review.

Time to Responseup to 24 months after completion of study treatment of the last participant

Defined as the time from randomization to first objective response (CR or PR per RECIST 1.1) based on the investigator's review.

Progression-Free Survival (PFS)up to 24 months after completion of study treatment of the last participant

Based on the investigator's tumor assessment according to RECIST 1.1. Defined as the time from randomization to first confirmed objective tumor progression (progressive disease per RECIST 1.1), or death from any cause, whichever occurs first.

PFS rateup to 24 months after completion of study treatment of the last participant

As measured at 6, 12, 18, and 24 months

Overall Survival (OS)up to 24 months after completion of study treatment of the last participant
