Trial Outcomes & Findings for Neoadjuvant Dupilumab in Men With Localized High-Risk Prostate Cancer (NCT NCT03886493)

NCT ID: NCT03886493

Last Updated: 2021-10-15

Results Overview

Change in M2-TAM infiltration (number of macrophages / cell nuclei per high power field \[hpf\]) measured in pre- dupilumab biopsy to M2-TAM infiltration measured in post-dupilumab specimen collected at time of radical prostatectomy (up to 59 days post-intervention). Degree of TAM infiltration will be analyzed using immunohistochemical staining for CD206. It is hypothesized that a positive value will be associated with better outcome and a negative value will reflect a worse outcome.

Measure
Dupixent Subcutaneous (SQ) Injection
Participants will be treated with dupilumab 600 mg SQ on day 1, and then 300 mg SQ on days 8,15, 22, 29, 36, 43. They will then undergo surgery on day 57. 14 days after the last dose of Dupixent, prostate glands will be harvested at the time of radical prostatectomy, and prostate tissue will be examined for the secondary endpoints. Dupilumab: dupilumab 600 mg SQ on day 1, and then 300 mg SQ on days 8,15, 22, 29, 36, 43.
