Effect of Low-dose Interferon-alfa2a on Peri-operative Immune Suppression
- Registration Number
- NCT04798612
- Lead Sponsor
- Zealand University Hospital
- Brief Summary
The aim of this randomized double-blinded placebo-controlled phase 2 study is to determine efficacy of preoperative treatment with interferon-alfa2a in patients with pMMR colon cancer on perioperative immune suppression and infiltration of lymphocytes in the primary tumor.

- Arm && Interventions
Group Intervention Description Intervention arm Pegasys Two 45 mikrogram doses of interferon-alfa2a (Pegasys). Both will be applied subcutanously. First dose is at least one week before surgery. Second dose on the day of surgery before the procedure. Placebo Saline Two 1 ml doses of saline liquid. Both will be applied subcutanously. First dose is at least one week before surgery. Second dose on the day of surgery before the procedure.
- Primary Outcome Measures
Name Time Method Flow-analysis of lymphocytic subpopulations in blood Change between day of surgery (day 7-14 after first treatment) and postoperative day 1. Change in CD3, CD4, and CD8 between intervention and placebo groups
T-cell infiltration in tumor Day of surgery (day 7-14 after first treatment) Difference in CD3, CD4 and CD8 T-cell infiltration between intervention and placebo groups
- Secondary Outcome Measures
Name Time Method Quality of recovery (QoR-15) Third postoperative day and postoperative day 12-16 Difference in QoR-15 between intervention and placebo groups
Multiplex gene assay - NanoString Pan Cancer 360 IO panel analysis in blood and resected tumor Day of first treatment (Day 0) and day of surgery (day 7-14 after first treatment) Difference in gene expressions between intervention and placebo groups
cfDNA analysis in blood Day of first treatment (Day 0), day of surgery (day 7-14 after first treatment), postoperative day 2, postoperative day 12-16, and postoperative day 28-32. Difference between intervention and placebo groups
CRP and neutrophil/lymphocyte ratio Day of surgery (day 7-14 after first treatment) Difference in CRP and neutrophil/lymphocyte ratio between intervention and placebo groups
Immunological and inflammatory cytokines and interleukins Day of surgery (day 7-14 after first treatment) and postoperative day 1. Difference between intervention and placebo groups
Multiplex gene assay - NanoString Pan Cancer 360 IO panel analysis of tumor biopsy and resected specimen Day of standard endoscopic biopsy (Day -7-14 before treatment) and day of surgery (day 7-14 after first treatment) Difference in gene expressions in tumor biopsies and resected specimen between intervention and placebo groups
