E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
This is an open-label, non-randomized, multicentre phase II study with an initial safety-run in. During the safety run-in phase, we will investigate the safety of combining IMM-101 administration with SBRT in 20 patients with limited metastatic disease in the liver and/or lung. If deemed safe, we will continue inclusion in the second phase of the study with an additional 80 patients in order to evaluate the efficacy of combining IMM-101 treatment with SBRT based on a 100% improvement of progression free survival. The primary objective of the safety run-in is to determine safety of IMM-101 combined with SBRT in patients with limited metastatic pancreatic cancer. When this combination is found to be safe, the second phase of the study will be initiated, the primary objective of the phase II is to investigate the potential efficacy of IMM-101 combined with SBRT.

Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment. • Diagnosis of immunodeficiency or receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the planned first dose of the study. The use of physiologic doses of corticosteroids may be approved after consultation with the Sponsor. • History of Human Immunodeficiency Virus (HIV) (HIV-1/2 antibodies). • Active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA [qualitative] is detected). • Positive PCR test for presence of SARS-CoV-2 during screening stage. • Live virus vaccine within 30 days of planned start of trial treatment. • Use of herbal remedies, including traditional Chinese herbal products (e.g., mistletoe). • Allergic reaction to M. obuense or had previously received IMM-101. • Otherwise deemed unsuitable by the Investigator. *To be determined by the treating radiologist.

E.5 End points |
E.5.1 | Primary end point(s) |
Safety run-in The main goal of this study is to determine safety of IMM-101 and SBRT in patients with limited metastatic disease in the lung and/or liver from PDAC. The toxicity of IMM-101 and SBRT is defined according to Common Terminology Criteria for Adverse Events (CTCAE version 5). Safety will be assessed in terms of grade 3, 4 and 5 events related to the IMM-101 vaccination or SBRT before, during and after IMM-101 and SBRT in patients included in the standard and expansion cohort. With a sample size of 20 (10 per cohort), we will be able to estimate a toxicity rate of 10 % to within a 95% confidence interval of [1.2%, 31.7%] using the binomial exact method. This means at 95% confidence level max. up to 6 patients out of 20 patients can be allowed to have grade 3/4/5 toxicity. If up to a maximum of 6 patients out of 20 develop AEs related to IMM-101 administration, then we feel that including the remaining patients in the phase II study testing efficacy is warranted. All grade 3, 4 and 5 events related to the administration of the IMM-101 product will be considered events for this endpoint.
Phase II The main endpoint of the second inclusion phase is to asses efficacy of IMM-101 therapy and SBRT in patients with limited metastatic disease in the lungs and/or liver from PDAC. Efficacy will be determined using 1-year progression free survival. Progression free survival will be calculated from the start FOLFIRINOX to the date of death. With a power of 0,80 and α of 0.05 a total of 56 (standard cohort) and 44 (expansion cohort) (including patients of the safety run-in patients will be included in the phase II study to determine an increase of the 1-year progression-free survival from 12% to 24% (standard cohort) and 5% to 15% (expansion cohort) (Fleming’s procedure). All included patients (i.e. 100 patients) will be analysed for this endpoint. |
