About this study
Official title: A Phase II, Multi-site, Open-label, Parallel Group Trial of BNT327 in Combination With Chemotherapy for Participants With Untreated Extensive-stage Small-cell Lung Cancer and Participants With Previously Treated Small-cell Lung Cancer
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.
Read the 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.
- Being tested
- BNT327 Dose Level 1 (DL1), BNT327 Dose Level 2 (DL2), Etoposide, Carboplatin, Paclitaxel

Primary outcome
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
Time frame: 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
Time frame: up to 100 days after the last dose of treatment
By treatment arm and overall.
Objective Response Rate
Time frame: 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
Time frame: 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 comes first). By treatment arm.
Proportion of participants who have achieved early tumor shrinkage
Time frame: up 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.
10 secondary outcomes
PK assessment: Maximum concentration (Cmax) derived from serum concentration of investigational medicinal product (IMP)
Time frame: from pre-dose to 21 days after study treatment
PK assessment: Area under the curve during the dosing interval (AUCtau) values derived from serum concentration of IMP
Time frame: from pre-dose to 21 days after study treatment
Incidence of detectable BNT327 antidrug antibodies in serum
Time frame: from pre-dose to 100 days after last dose of study treatment
Duration of Response
Time frame: up to 24 months after completion of study treatment of the last participant
Disease Control Rate
Time frame: up to 24 months after completion of study treatment of the last participant
Time to Response
Time frame: up to 24 months after completion of study treatment of the last participant
Progression-Free Survival (PFS)
Time frame: up to 24 months after completion of study treatment of the last participant
PFS rate
Time frame: up to 24 months after completion of study treatment of the last participant
Overall Survival (OS)
Time frame: up to 24 months after completion of study treatment of the last participant
OS rate
Time frame: up to 24 months after completion of study treatment of the last participant

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing BNT327 Dose Level 1 (DL1), BNT327 Dose Level 2 (DL2) and Etoposide in people with Extensive-stage Small-cell Lung Cancer and Small-cell Lung Cancer, run by BioNTech SE at 64 sites in 5 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 0 inclusion and 49 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 6 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 64 sites in Turkey (Türkiye), United States, United Kingdom, South Korea, Australia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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 (time frame: up to 100 days after the last dose of treatment). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026.
