About this study

Official title: A Phase I/II, Randomized, Multi-site Trial to Investigate the Efficacy and Safety of BNT314 in Combination With Pumitamig and Chemotherapy in Participants With Metastatic Colorectal Cancer

This randomized, multi-site, three-part study will test a new treatment called BNT314, which is designed to help the body's own defense to fight cancer in combination with another new treatment (pumitamig, which is a cancer immunotherapy drug also known as BNT327 and PM8002) and chemotherapy in participants with metastatic colorectal cancer (mCRC).

Read the detailed description

Participants with microsatellite stable or mismatch repair proficient (MSS/pMMR) mCRC with progressive disease to the metastatic first line (1L) setting (Parts B and C) and beyond (Part A) as well as treatment-naïve (for Part B) are eligible to participate in the study.

The main study goals are as follows:

  • Part A (Phase 1, safety run-in, dose escalation): To see if BNT314 in combination with pumitamig can be given safely, without causing severe side effects in participants.
  • Part B (Phase 1, dose optimization): To see if BNT314 in combination with pumitamig and standard of care (SoC) chemotherapy is safe for participants and to find out the right dose of BNT314 that can be used in Part C.
  • Part C (Phase 2, randomization against SoC): To see how well treatment works when BNT314 and pumitamig are given in combination with the usual SoC chemotherapy treatment.

In all three parts, the study will also look whether BNT314 can shrink tumors or slow down their growth when used with pumitamig and chemotherapy.

The study consists of a period to assess eligibility, a treatment period, a safety follow-up period, and a long-term survival follow-up period.

The sponsor plans to proactively assess participant safety on a regular basis for the duration of the study according to a predefined internal review committee. In addition, an independent data monitoring committee will be developed to provide medical oversight over Part C of the study.

Participants in the study will continue to receive treatment until their disease worsens, they can no longer tolerate the treatment, the participant chooses to leave the study, or the study ends. They are expected to be on treatment for about of 6-10 months on average. Participants may stop treatment early if their disease worsens or side effects occur but can continue longer if the disease stays controlled and the therapy is well-tolerated. After that, they will be monitored for their survival and any potential long-term side effects even after they stop participating in the study. Participants will be randomized to the treatment groups in Part B and Part C, which means participants will be assigned by equal chance to a treatment group.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing BNT314, Pumitamig and SoC chemotherapy treatment 1 in people with Metastatic Colorectal Cancer, run by BioNTech SE at 14 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 13 inclusion and 19 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 1 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in United States, Spain, United Kingdom, Germany, Japan. 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?

Phase I - Part A: Occurrence of dose limiting toxicities (DLTs) during the DLT observation period (time frame: Up to 28 days after Day 1, Cycle 1). The study lists 8 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 1 Jul 2026.
