5. Study Description

Brief Summary
This is a Phase 1b study evaluating a combination of PEGPH20 and pembrolizumab in hyaluronan-high (HA-high) participants with relapsed/refractory non-small cell lung cancer (NSCLC) and HA-high participants with relapsed/refractory gastric adenocarcinoma (GAC).
Detailed Description
Study involves dose escalation phase (completed in Nov-2016) to assess the safety and tolerability of PEGPEM (PEGylated recombinant human hyaluronidase [PEGPH20] combined with pembrolizumab [Keytruda®]) and to find the recommended Phase 2 dose (RP2D) ; and an expansion phase to assess the efficacy, safety and tolerability of PEGPEM in stage III b/IV NSCLC and relapsed/refractory GAC participants. Plan was to include approximately 51 HA-high participants (30 NSCLC and 21 GAC participants) in the dose expansion phase on the obtained RP2D from dose escalation phase of the study.

Dose- Expansion Phase: DCR, as Assessed by Investigator Based on irRC: Percentage of Participants Who Achieved CR, PR or SD
Description
DCR was defined as percentage of participants who achieved CR, PR, or stable disease (SD). CR was defined as disappearance of all lesions including non-index lesions and new non-measurable lesions, lymph nodes must be <10 mm in short axis). PR was defined as at least a 30% decrease in tumor burden from baseline. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PD was defined as at least a 20% increase in tumor burden from nadir.
Time Frame
From first dose until first occurrence of CR, PR or SD (maximum exposure: 60 weeks for GAC, and 46 weeks for NSCLC)
Title
Dose- Expansion Phase: PFS, as Assessed by Investigator Based on irRC
Description
PFS was defined as the time from first dose date until the first occurrence of either radiographic or clinical disease progression as determined by the Investigator or death from any cause before discontinuation from treatment. Disease progression was defined as at least a 20% increase in tumor burden from nadir. PFS was analyzed using Kaplan-Meier methods.
Time Frame
From first dose until the first occurrence of either radiographic or clinical disease progression or death from any cause (maximum exposure: 60 weeks for GAC, and 46 weeks for NSCLC)

Title
Number of Participants With Adverse Events (AEs)
Description
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. AEs included both SAEs and non-serious AEs. A summary of other non-serious AEs and all SAEs, regardless of causality is located in the 'Reported AE section'.

Title
Dose-Expansion Phase: Number of Participants With Clinically Significant Abnormalities in Clinical Laboratory Parameters and Vital Signs
Description
Clinical laboratory parameters included hematology (haemoglobin [Hb], hematocrit, red blood cell count, white blood cell count, neutrophils [ANC], lymphocytes, monocytes, eosinophils, basophils, granulocytes, mean corpuscular Hb, mean corpuscular volume, and platelet count) and blood chemistry (glucose, blood urea nitrogen [BUN], alanine aminotransferase [ALT], aspartate aminotransferase [AST], albumin, bilirubin, bicarbonate, calcium, chloride, magnesium, potassium, sodium, thyrotropin, thyroxin, triiodothyronine, alkaline phosphatase [ALP], electrolytes, and creatinine). Vital signs included measurement of blood pressure (systolic and diastolic), pulse, respiratory rate, and body temperature. Criteria for clinical significance were as per investigator's discretion.
Time Frame
Cycle 1 Day 1 up to 30 days after last dose of study drug (maximum exposure: 60 weeks for GAC, and 46 weeks for NSCLC)

Time Frame
Cycle 1 Day 1 up to 30 days after last dose of study drug (maximum exposure: 60 weeks for GAC, and 46 weeks for NSCLC)

Eligibility Criteria
Inclusion Criteria: Dose Expansion: Histologically confirmed and documented, previously untreated or treated stage IIIB or IV 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 regimens for locally advanced or metastatic disease. Participants with NSCLC who are known to be epidermal growth factor receptor (EGFR)-mutation positive must have received an EGFR inhibitor and participants 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: • For participants in the dose expansion portion of the study, it is mandatory that available archived tumor tissue in formalin-fixed. paraffin-embedded (FFPE) block or minimum 10-15 unstained consecutive core biopsy slides from 1 archival block that meet specific tissue requirements are available.
