Further study details as provided by Halozyme Therapeutics:

Primary Outcome Measures:
  • Efficacy of PEGPH20 and pembrolizumab combination by Objective response rate (ORR) [ Time Frame: Expansion phase ]
    based on RECIST v1.1 (Response Evaluation Criteria in Solid Tumors v.1.1) in Hyaluronan-high (HA-high) subjects

Secondary Outcome Measures:
  • Duration of response (DOR) based on RECIST v1.1 and immune related response criteria (irRC) [ Time Frame: Expansion phase ]
    during the expansion phase

  • Disease control rate (DCR) based on RECIST v1.1 and irRC [ Time Frame: Expansion phase ]
    during the expansion phase

  • PFS based on RECIST v1.1 and irRC [ Time Frame: Expansion phase ]
    during expansion

Estimated Enrollment: 81
Study Start Date: October 2015
Estimated Study Completion Date: September 2018
Estimated Primary Completion Date: May 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PEGPEM
PEGPH20 + pembrolizumab
PEGPH20 + pembrolizumab

Detailed Description:

Study involves dose escalation phase (completed in Nov-2016) to find the RP2D dose and an expansion phase to assess the safety and tolerability of the RP2D dose within stage III b/IV NSCLC and relapsed/refractory gastric adenocarcinoma subjects.

Plan is to include approximately 51 HA-high subjects (30 NSCLC and 21 GAC subjects) in the dose expansion phase on the obtained RP2D from dose escalation phase of the study.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Dose Expansion: Histologically confirmed and documented, previously untreated or treated stage IIIB or IV Non-Small Cell Lung Cancer (NSCLC) having failed no more than 1 previous platinum containing chemotherapy regimen for locally advanced or metastatic disease or relapsed/refractory locally advanced or metastatic gastric adenocarcinoma having failed no more than 2 previous chemotherapy regimen for locally advanced or metastatic disease. Subjects with NSCLC who are known to be epidermal growth factor receptor (EGFR)-mutation positive must have received an EGFR inhibitor and subjects known to be anaplastic lymphoma kinase (ALK)-mutation positive must have received an ALK inhibitor.

Prior to enrollment, confirmation of the following must be obtained:

• Dose expansion - For subjects in the dose expansion portion of the study, it is mandatory that available archived tumor tissue in FFPE block or minimum 10 unstained consecutive core biopsy slides from 1 archival block that meet specific tissue requirements are available.

  • One or more tumors measurable on CT scan/MRI scan per RECIST v 1.1. - Previously irradiated tumors may be eligible if they have clearly progressed in size.
  • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.
  • Life expectancy ≥3 months.

Subjects must also satisfy the following inclusion criterion:

  • Subjects (NSCLC and gastric adenocarcinoma) must be determined to have HA-high levels from their tumor biopsies.
  • NSCLC and gastric adenocarcinoma subjects must have tissue available for HA-selection and PD-L1 testing.

Exclusion Criteria:

  • Previous treatment with pembrolizumab, nivolumab, or other programmed cell death-1 antibody (anti- PD-1) or PD-1 ligand-antibody (anti-PD-L1) agents.
  • New York Heart Association Class III or IV (Appendix D) cardiac disease or myocardial infarction within the past 12 months before screening, or preexisting atrial fibrillation.
  • Prior history of cerebrovascular accident or transient ischemic attack.
  • NSCLC subjects with known brain metastases (certain exceptions allowed)
  • Gastric adenocarcinoma subjects with brain metastases
  • History of active bleeding within the last 3 months requiring transfusion
  • Anti-angiogenic therapy within the last month
  • Patients with known interstitial fibrosis or interstitial lung disease.
  • Previous history of pulmonary embolism or pulmonary embolism found on screening exam.
  • Active autoimmune disease requiring systemic treatment within the past 3 months or documented history of clinically severe autoimmune disease, or syndrome that requires systemic steroids or immunosuppressive agents.
  • History of another primary cancer within the last 3 years that required treatment, with the exception of non-melanoma skin cancer, early-stage prostate cancer, or curatively treated cervical carcinoma in situ.
