Study of Neoadjuvant Imprime PGG and Pembrolizumab for Stage III, Resectable Melanoma

NCT04995094 · Status: WITHDRAWN · Phase: PHASE2 · Type: INTERVENTIONAL

Last updated 2021-11-05

No results posted yet for this study

Summary

Approximately 50 ABA+ subjects with resectable, Stage III (IIIB, IIIC, or IIID) melanoma will be included in the study and randomized in a 3:2 ratio to neoadjuvant treatment with Imprime PGG plus pembrolizumab vs. pembrolizumab monotherapy. A baseline, reference biopsy and a PET/CT scan will be obtained prior to commencing 3 cycles (9 weeks) of neoadjuvant treatment with either regimen. During Week 5, subjects will provide another biopsy to assess treatment effects on the tumor and its microenvironment. At the completion of neoadjuvant treatment and before surgery, subjects will undergo another PET/CT scan to assess radiological and metabolic response compared to baseline.

Conditions

  • Pathologic Stage III Cutaneous Melanoma AJCC v8

Interventions

BIOLOGICAL

Imprime PGG

Imprime PGG is a soluble, β-1,3/1,6 glucan isolated from the cell wall of a proprietary Saccharomyces cerevisiae yeast strain. Imprime PGG acts as a Pathogen-Associated Molecular Pattern (PAMP). Imprime will be administered at a dose of 4 mg/kg IV over a 2-hour infusion time on Days 1, 8 and 15 of each 3-week treatment cycle.

BIOLOGICAL

Pembrolizumab

Pembrolizumab is a humanized monoclonal antibody against the programmed death receptor-1 (PD-1) protein. Pembrolizumab will be administered at 200 mg IV Q3W for 9 weeks.
