Trial Outcomes & Findings for Study of Gemcitabine + PEGPH20 vs Gemcitabine Alone in Stage IV Previously Untreated Pancreatic Cancer (NCT NCT01453153)

Last Updated: 2018-11-30

Results Overview

The safety and tolerability profile of PEGPH20 used in combination with gemcitabine was assessed by measuring the number of participants with a DLT during the dose-escalation phase of the study. A DLT was defined as any treatment-emergent National Cancer Institute (NCI) Common Terminology Criteria for Adverse Event (CTCAE), Version 4.0, Grade 3 or greater event occurring within the first 4 weeks of treatment that was considered related to PEGPH20. Any PEGPH20 treatment-related AE that resulted in a drug interruption or reduction might have been considered a DLT at the Investigator's or Sponsor's discretion. Hypersensitivity/infusion reactions related to PEGPH20 dosing were not considered DLTs.

Participant Flow

This study was to consist of a Phase 1b and a randomized Phase 2 study. However, the randomized Phase 2 study was not conducted due to a change to the standard-of-care chemotherapy treatment to be used in combination with PEGylated Recombinant Human Hyaluronidase PH20 (PEGPH20).

PRIMARY outcome

Timeframe: first 4 weeks of Cycle 1

The safety and tolerability profile of PEGPH20 used in combination with gemcitabine was assessed by determining the RP2D, the highest dose level at which no more than 1 of 6 evaluable participants experienced a DLT in the first 4 weeks of treatment (considered a safe dose). The RP2D was determined based on review of safety and pharmacokinetic (PK) data from participants enrolled during the dose-escalation phase of the study.

Timeframe: Baseline; post-Baseline (average treatment duration of 94.6 days)

Population: Intent-to-Treat Population. This study was to consist of a Phase 1b and a randomized Phase 2 study. However, the randomized Phase 2 study was not conducted due to a change to the standard-of-care chemotherapy treatment to be used in combination with PEGPH20.

The pharmacodynamic activity of PEGPH20 was evaluated by measuring plasma concentrations of HA after PEGPH20 dosing. Peak HA concentrations are the highest concentrations measured after a single dose of PEGPH20. HA samples were collected in Cycle 1 at the following time points: 1) Week 1/Day 1 (first visit) and Week 4 (first visit): predose and 15 minutes, 1, 2, 4, and 24 hours post-PEGPH20 dosing (24-hour sample optional for Week 4); 2) all other visits in Cycle 1: pre-PEGPH20 dose, 1 to 2 hours post-PEGPH20 dose, and immediately after the dose of gemcitabine (on the days gemcitabine was given). HA samples were collected in Cycles 2+ at the following time points: Week 3 of each cycle pre-PEGPH20 dose and 1 to 2 hours post-PEGPH20 dose.

Timeframe: Screening; Cycle 1 Week 7

Population: Intent-to-Treat Population. Only 1 participant had a screening and post-treatment specimen that qualified for staining. This study was to consist of a Phase 1b and a randomized Phase 2 study. However, the randomized Phase 2 study was not conducted due to a change to the standard-of-care chemotherapy treatment to be used in combination with PEGPH20.

An H-score approach methodology was developed and used to analyze staining in the tumor pericellular regions and the stroma separately. The H-score calculation was the sum of the products of the percentage of positive staining areas and the staining intensity (0, 1, 2 or 3), and ranged from 0 to 300. For example: \[90% \* 1 (weak)\] + \[10% \* 2 (moderate)\] + \[0% \* 3 (strong)\] = 110. A score of 0 represents the absence of expression, and an H-score of 300 represents maximum expression. A larger decrease in H-score correlated with a greater target engagement of PEGPH20. As HA is a secreted protein, the scoring was performed in the immediate areas surrounding tumor (pericellular areas) as well as in stroma.

SECONDARY outcome

Timeframe: Baseline; up to 32 weeks for each individual participant (end of Cycle 7)

Population: Intent-to-Treat Population. Only those participants with available data were analyzed. This study was to consist of a Phase 1b and a randomized Phase 2 study. However, the randomized Phase 2 study was not conducted due to a change to the standard-of-care chemotherapy treatment to be used in combination with PEGPH20.

PEGPH20's effect on the metabolic activities of the tumor was assessed as the percent change in SUVmax (a measure of total lesion metabolic activity) using fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT). Assessment was done for the entire cohort of participants, not per treatment group.

Population: ITT Population. DCE-MRI scans were performed for 6 participants. Only participants with data available were analyzed. This study was to consist of a Phase 1b and a randomized Phase 2 study. However, the randomized Phase 2 study was not conducted due to a change to the standard-of-care chemotherapy treatment to be used in combination with PEGPH20.

Dynamic control enhanced-magnetic resonance imaging (DCE-MRI) provides a measure of the exchange of small-molecule contrast agents between the intracellular and extracellular spaces. Using a 2-compartment pharmacokinetic model, an estimate of tissue (tumor) perfusion can be obtained by determining the exchange rate constant (Ktrans) of contrast exchange. Ktrans is defined as the volume transfer constant between extravascular/extracellular space to plasma space and is a measure of blood flow, vascular permeability, or both. Mean Ktrans values across scan sites are reported per participant. DCE-MRI was performed before the first dosing visit (Week 1/Day 1), 24 hours after the first dose of PEGPH20 in Cycle 1, and 24 hours after the last dose of PEGPH20 in Cycle 1 (Week 7). Assessment was done for the entire cohort of participants, not per treatment group.

Timeframe: up to approximately 2 years 4 months

Disease Control Rate is defined as the sum of the number of participants with a complete response, the number of participants with a partial response, and the number of participants with stable disease per RECIST, Version 1.1. For TLs, CR: Disappearance of all TLs. PR: \>=30% decrease in the sum of diameters of TLs, referencing baseline sums. SD: Neither sufficient shrinkage to qualify for PR nor sufficient to qualify for PD, referencing the smallest sum diameters. For NTLs, CR: Disappearance of all NTLs and normalization of tumor marker level. All lymph nodes must be nonpathological in size (short axis \<10 mm). Incomplete response/SD: Persistence of \>=1 NTLs and/or maintenance of tumor marker level above normal limits.

SECONDARY outcome

Timeframe: from the first dose of PEGH20 until objective tumor progression or death (up to approximately 2 years 4 months)

PFS duration was defined as the time from the first dose of PEGPH20 until objective tumor progression or death. Per RECIST, Version 1.1, for the evaluation of target lesions, progressive disease is defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 millimeters. Note: the appearance of 1 or more new lesions is also considered progression. For the evaluation of nontarget lesions, progressive disease is defined as the unequivocal progression of existing nontarget lesions. Note: The appearance of 1 or more new lesions is also considered progression.

Measure	PEGPH20 1.0 μg/kg n=4 participants at risk Participants received PEGylated Recombinant Human Hyaluronidase PH20 (PEGPH20) 1.0 micrograms per kilogram (μg/kg). PEGPH20 was administered twice weekly for 4 consecutive weeks and then once weekly for the next 3 weeks during Cycle 1. For each cycle thereafter, PEGPH20 was administered once weekly for 3 consecutive weeks. Participants received gemcitabine 1000 milligrams per meters squared (mg/m\^2) administered via intravenous (IV) infusion. Before the Recommend Phase 2 Dose (RP2D) was established, gemcitabine was administered 2 hours after the second dose of PEGPH20 during Weeks 1 to 4 of Cycle 1 and on the same day as PEGPH20 during each week thereafter. After the RP2D was established, gemcitabine was administered within 24 hours after the first dose of PEGPH20 during Weeks 1 to 4 of Cycle 1 and 2 to 24 hours after each PEGPH20 dose thereafter. Dexamethasone was administered approximately 1 hour prior to and 8 to 12 hours after PEGPH20 dosing.	PEGPH20 1.6 μg/kg n=4 participants at risk Participants received PEGPH20 1.6 μg/kg.
