About this study

Official title: A Phase I Study on the Safety and Immune-modulatory Effect of Intratumoral (i.t.) Administration of mRNA (Messenger RNA) Encoding Dendritic Cell Activating Proteins in Patients With Early, Resectable Breast Cancer

Patients with early breast cancer and accessible tumor lesions (1.00 to 10 ml volume) that are eligible to either surgical removal of their tumor or neoadjuvant chemotherapy will be injected with the IMP. Patients will be either treated with placebo (buffer alone, 12 patients) or with TriMix mRNA at three dose levels [8 at dose level I (1mg/ml), 8 at dose level II (3mg/ml), and 8 at dose level III (6mg/ml). The volume injected in this group will be adjusted to the tumour volume to ensure a perfusion of around 33% of the tumour volume (33% +/- 5%). Therefore, depending on the patients' tumour size, 500, 1000 or 2000 µl of TriMix mRNA solution or placebo solution will be injected into each tumor. Each patient will receive three administrations of TriMix prior to start of general treatment (surgery or neoadjuvant chemotherapy) separated by one week (7 days +/- 2 days) interval. The last administration will be performed 2 days preoperatively or start of neoadjuvant chemotherapy.

The tumor and peripheral blood samples will be analyzed for immunological changes. If it is decided by the multidisciplinary team that neoadjuvant therapy is more appropriate for the patient, a second tumor biopsy (instead of surgical resection) will be taken 2 days after third administration of TriMix mRNA to assess immunological changes within the tumor. Similarly, patients that refuses to undergo surgery or to receive neoadjuvant chemotherapy can be enrolled into the trial, if they accept three administrations of TriMix followed by a second tumor biopsy.

The study will start with recruitment of the placebo group. The enrollment of the first three patients in each cohort with Trimix mRNA will be staggered with at least one day between the first dose of each individual patient. One week after the third patient of a cohort received the third TriMix mRNA administration, an overall evaluation of the safety and tolerability of this cohort will be done by the principal investigator. The results will be reviewed by an in-house dose evaluation committee overseeing the safety and tolerability of TriMix mRNA.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Trimix in people with Breast Cancer Female and Early-stage Breast Cancer, run by Universitair Ziekenhuis Brussel at 1 site in Belgium.

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 17 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 19 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Belgium. 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. Some participants in this study may receive a placebo. 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 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.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact UZ Brussel (+32 2 477 6015, borstkliniek@uzbrussel.be), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 (time frame: 2 years). 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 19 May 2022.
