About this study

Bazedoxifene, a selective estrogen receptor modulator is thought to have effective anti-tumoral properties for pancreatic cancer via IL-6 pathway (GP130/STAT3) inhibition.

The objective is to measure IL-6 (GP130/STAT3)-pathway modification on metastasis biopsy of patients with metastatic pancreatic adenocarcinoma before and after treatment with bazedoxifene in addition to chemotherapy.

This study is a single-center, prospective, nonrandomized trial.

Read the detailed description

This study is a single-center, prospective, non-randomized trial. The population studied will consist of 10 patients of both sexes, aged 18 to 85 years, with a newly diagnosed metastatic pancreatic adenocarcinoma who will undergo palliative treatment with standard first line chemotherapy (Gemcitabine +/- Nab-paclitaxel). Diagnosis must be confirmed by biopsy and metastasis must be accessible for percutaneous biopsy using imaging guidance. Further, only patients with an IL-6 (GP130/STAT3)-pathway activity of more than 5% on diagnostic biopsy will be included .

In addition to chemotherapy, patients will receive 20 mg bazedoxifene (Conbriza®) orally per day, subject to good clinical tolerance and in the absence of a biological contraindication.

Patients will receive bazedoxifene once a day at any time, with or without meals. Initiation of treatment will be simultaneous to the initiation of chemotherapy. Bazedoxifene (Conbriza®) will be prescribed and administered for the duration of the study. To minimize the risk of thrombo-embolic events, prophylactic rivaroxaban (Xarelto®) 10 mg orally once per day will be added for the duration of the bazedoxifene (Conbriza®) intake. Pantoprazole 20 mg once per day will be added in selected patients to minimize gastric complications according to the physician's appreciation. Participants will receive bazedoxifene (Conbriza®) and rivaroxaban (Xarelto®) for the entire study duration from a subinvestigator at treatment initiation visit.

Physical examination with vital parameters, laboratory testing (blood count, liver enzymes, creatinine) and tumor marker (CA 19-9) will be conducted in order to determine the baseline prior to the initiation of the treatment. The quality of life using the EORTC core quality of life questionnaire (QLQ-C30) will also be assessed at that point. Furthermore, the IL-6 pathway activity (GP130/STAT3) will be assessed immunohistochemically on metastasis biopsy before administration of bazedoxifene (Conbriza®). The tissue will be obtained by percutaneous biopsy using imaging guidance. A biopsy performed before study inclusion can be used as baseline to avoid a second biopsy.

Study enrollment and follow-up will be performed by the consultant physician at the HFR Fribourg in the department of oncology. The follow-up will be carried out every 3 to 4 weeks and will consist of a physical examination, vital parameters, laboratory testing (blood count, liver enzymes, creatinine, electrolytes) and tumor marker (CA 19-9). Plasma samples will be collected before and after treatment for storage and samples will be analyzed through next generation sequencing NGS. Quality-of-life will be assessed during the follow-ups and drug adherence will be monitored through patient survey.

After 3 months of treatment, the primary endpoint will be assessed. Thoraco-abdominal CT scan or PET-CT will be performed, and a biopsy of metastasis tissue will be repeated (percutaneous under radiological guidance) for immunohistochemical IL-6 pathway activity (GP130/STAT3) analysis. The activity of bazedoxifene (Conbriza®) on inflammatory pathways and tumor progression will be evaluated by comparing the modification in expression of the IL-6 pathway (GP130/STAT3) from baseline.

Patients will be instructed by the investigator to report the occurrence of any adverse event.

The expected duration of the study for each participant will be 12 to 16 weeks.
