Arm Intervention/treatment
Experimental: Arm A - Phase Ib

Dose Escalation Cohort Cohort 1 will consist of 3-6 patients who will receive pembrolizumab 200mg IV on Day 1 of each 21 day cycle. Imprime PGG will be administered at 2mg/kg on Day 1,8, and 15 of cycles 1-4, and on Day 1 of cycles 5-16. On Day 1 of each cycle, the Imprime PGG intravenous infusion is given first followed 15-30 minutes later by the pembrolizumab.

Experimental: Arm A - Phase II Investigational Treatment The maximum safe dose of Imprime PGG in combination with pembrolizumab (as determined in the phase Ib cohort) will be given on Day 1,8, and 15 for cycles 1-4, and on Day 1 of cycles 5-16.

Cohort 2 will consist of 3-6 patients who will receive pembrolizumab 200mg IV on Day 1 and Imprime PGG at 4mg/kg on Day 1,8, and 15 for Cycles 1-4 and on Day 1 only for Cycles 5-16. On Day 1 of each cycle, the Imprime PGG intravenous infusion is given first followed 15-30 minutes later by the pembrolizumab.

  2. Clinical Benefit Ratio [ Time Frame: From the start of treatment D1 assessed every 6 weeks +/- 1 week while on study treatment (up to 11 months [16 cycles]) ]
    Clinical Benefit Ratio (complete, partial response, or stable disease) as assessed per RECIST 1.1.

  3. Progression Free Survival (PFS) at 6 months [ Time Frame: 6 months ]
    Estimate Progression-Free Survival (PFS) and 6-month PFS using RECIST v1.1 in subjects with NSCLC when treated with Imprime PGG in combination with pembrolizumab who progressed after first-line systemic therapy.

  4. Overall Survival (OS) [ Time Frame: from the start of the treatment until death from any cause (up to 1 year from start of treatment) ]
    To determine the overall survival for this patient population at 1 year.

  • Previous exposure or known allergy to Imprime PGG or any of its excipients.
  • Known hypersensitivity to Chinese hamster ovary cell products or other recombinant human antibodies.
  • Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration, interfere with protocol compliance, or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the subject inappropriate for enrollment in this study.
