About this study
Official title: A Phase Ib/II, Multi-site, Open-label, Two-part Trial to Evaluate the Efficacy, Safety, Pharmacokinetics, and Recommended Combination Dose of BNT324 With BNT327 in Participants With Advanced Lung Cancer
This study aims to investigate the combination of BNT324, a B7-H3 antibody-drug conjugate (ADC) with BNT327, a programmed death-ligand 1 (PD-L1) and vascular endothelial growth factor (VEGF) bispecific antibody, in participants with advanced/metastatic or relapsed/progressive small cell lung cancer (SCLC) and non small cell lung cancer (NSCLC).
Read the detailed description
This is a two-part study designed to evaluate and establish two safe combination dose levels (recommended Phase 2 dose [RP2D] and a lower/another combination dose level [RP2D-1]) of BNT324 with BNT327 (Part 1), to determine the optimal combination dose (dose optimization [DO]) in NSCLC and SCLC lead indication cohorts at the RP2D and RP2D-1, to evaluate the preliminary efficacy in selected lung cancer cohorts at the highest combination dose level (in a signal seeking Part 2), and to confirm the clinical efficacy of BNT324 in combination with BNT327 at the optimal dose level in participants with advanced lung cancer in expansion cohorts (proof-of-concept [POC] cohorts).
The study consists of a screening period, a treatment period, a safety follow-up period, and a long-term survival follow-up period.
In Part 1 participants with histologically or cytologically confirmed relapsed or progressive lung cancer (both SCLC and NSCLC are eligible) will receive BNT324 in combination with BNT327 using a dose escalation design.
In Part 2 of the study, BNT324 will be studied in combination with BNT327 at the RP2D compared to RP2D-1 in participants with advanced metastatic treatment-naïve NSCLC (DO Cohort 1) and relapsed/progressive SCLC after failure of cytotoxic chemotherapy with or without immuno-oncology (IO) (DO Cohort 2). The totality of the available data (e.g., safety, efficacy, pharmacokinetics etc.) will be reviewed to select the optimal dose. After the optimal dose is selected, additional participants in each cohort may be enrolled in the selected optimal dose.
In the signal seeking cohorts (Cohort 3-7), participants will receive BNT324 in combination with BNT327 at the RP2D from Part 1.
A predefined number of participants in Part 2 Cohort 1 and Cohort 2 will be randomized to one of the two dose levels (RP2D and RP2D-1) selected from Part 1 in a 1:1 ratio. Additional participants in Part 2 Cohort 1 and Cohort 2 may be enrolled in the selected optimal dose to further assess the efficacy and safety profile.
No randomization is planned for any other cohort in Part 2 or Part 1.

Key inclusion criteria (13 listed)
- Aged ≥18 years at the time of giving informed consent.
- Histological or cytological confirmed unresectable advanced/metastatic lung cancer. Histological classification may be based on tumor samples prior to metastatic disease. Participants with mixed histology must be classified based on the main component. Participants with NSCLC are eligible with any or no PD-L1 expression. Participants with AGA-positive disease must have received targeted therapy prior to enrollment in this study.
- Have measurable disease defined by RECIST version 1.1.
- Have an Eastern Cooperative Oncology Group performance status of 0 or 1.
- Have a life expectancy of ≥12 weeks.
Key exclusion criteria (5 listed)
- Prior treatment with B7-H3 targeted therapy.
- Prior treatment with ADC with topoisomerase inhibitor (e.g., datopotamab deruxtecan, trastuzumab deruxtecan). Note: This exclusion applies to participants in the first-line/treatment-naïve cohorts in the advanced/metastatic setting. Prior treatment with ADC with topoisomerase inhibitor payload is only allowed for participants in the second-line plus cohorts in the advanced/metastatic setting.
- Is a candidate to locoregional treatment (including surgical resection, stereotactic radiotherapy or tumor ablation) with potential to induce complete or near complete response and prolonged tumor control (sometimes described as "radical" intent), per investigator's assessment.
- Has a history of significant hematologic toxicity to prior lines of therapy, as assessed by investigator, e.g., Grade 4 febrile neutropenia or recurrent/persistent Grade 3 to 4 neutropenia.
- NOTE: Other protocol defined Inclusion/Exclusion criteria may apply to all or some participants depending on the cohort.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing BNT324 and BNT327 in people with Advanced Lung Cancer, run by BioNTech SE at 91 sites in 10 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 13 inclusion and 5 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: looking for participants now, as of the sponsor's last update on 26 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 91 sites in China, United States, Spain, Turkey (Türkiye), United Kingdom and 5 more countries. 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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Contact BioNTech clinical trials patient information (+49 6131 9084 ext. 0, patients@biontech.de), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Part 1 - Occurrence of dose limiting toxicities (DLTs) by dose level (time frame: During the DLT evaluation period, i.e., the time of initiation of the first dose of investigational medicinal product (IMP) up to 21 days]). The study lists 7 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 26 Aug 2026.
