Descriptive Information
Brief Title  ICMJE Intratumoral TriMix Injections in Early Breast Cancer Patients
Official Title  ICMJE 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
Brief Summary

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.

Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 1
Study Design  ICMJE Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Masking: Single (Participant)
Masking Description:
Subjects will not know whether an active or non-active substance is being injected. The choice for TriMix or placebo will take place according to the predefined schedule and can not be influenced by the patient or the investigator. Only after the comparison of the tumour tissue before (the initial biopsy where the diagnosis was made) and after (obtained at second biopsy or surgery) the intratumoral injection, it will be known whether mRNA or non-active product was used for the injection.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Age greater than or equal to 18 years and less than or equal to 85 yrs
  2. Histologically proven breast cancer eligible for curative surgery (with or without the need for neoadjuvant chemotherapy) with one or more injection-accessible (allowing ultrasound guidance) nodal tumors.
  3. Injectable tumor lesions must have a volume between 1.00 and 10 ml, only one lesion per patient will be injected
  4. ECOG performance status of 0 or 1
  5. Willing to give informed consent in writing
  6. Willing and able to attend the scheduled study visits and to comply with the study procedures
  7. No prior therapy for ipsilateral breast cancer
  8. Availability of a diagnostic biopsy for immunological analysis
  9. Normal lab parameters: white cell count ≥ 3,000/mm3, hemoglobin ≥ 10mg/dl, platelet count ≥ 100,000/mm3, serum creatinine ≤ 1.5 x institutional ULN, bilirubin ≤ 2.0 mg/dl aspartate aminotransferase/alanine aminotransferase/ alkaline phosphatase ≤ 2 x the upper normal limit (AST< 72 U/l, ALT < 104 U/l, AP < 252 U/l)
  10. Adequate Coagulation Parameters with: Prothrombin INR < 1.5; Partial Thromboplastin Time < 1.5 x 34.4 sec (51.6 sec)
  11. Female patients of childbearing potential should have a negative serum pregnancy test at screening visit and should use a highly efficient method of birth control for the duration of treatment and until the first menses after a 4 week period after the last dose of study medication. Highly effective birth control methods include:

    • combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation administered oral, intravaginal or transdermal.
    • progestogen-only hormonal contraception associated with inhibition of ovulation administered oral, as an injectable or implantable formulation.
