E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to determine the potential improvement of Progression Free Survival (PFS) rate at 16 weeks with ERY001 combined with gemcitabine or FOLFOX4 chemotherapy, in a population of patients with progressive metastatic pancreatic adenocarcinoma, after progression under a first line of chemotherapy, over 18 years. |
|
E.2.2 | Secondary objectives of the trial |
Secondary
- Assess the overall tolerance of ERY001 in combination with gemcitabine or FOLFOX4 chemotherapy as second line of chemotherapy.
- Evaluate tumor response through clinical and biological markers over time
- Evaluate PK/PD and immunogenicity parameters of ERY001
- Evaluate treatment adherence
- Assess potential association between response and ASNS expression level (no or weak) on tumor
- Evaluation of the Quality of Life
Exploratory
- To assess circulating tumor DNA: The aim is to assess the predictive value of circulating tumor DNA variations during the course of treatment. All patients will be eligible for circulating tumor DNA analysis.

E.5 End points |
E.5.1 | Primary end point(s) |
PFS rate of ASNS 0-1 patients with ERY001 at Month 4 (week 16).
Progression is defined as per local evaluation as:
- appearance of one or more new lesions,
- increase in the size of target measurable lesions (greater than or equal to 20% of the sum of the largest diameters according to RECIST criteria version 1.1)
Progression-free survival is defined as the time from randomization to time of objective disease progression or death related to medical condition.
Medical images will be centrally reviewed. These central reads RECIST data will be supportive only and will be performed as sensitivity analysis. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Timepoint(s) of evaluation of Primary end points are described in E.5.1 |
|
E.5.2 | Secondary end point(s) |
Secondary endpoints:
- Overall tolerance of the Frequency, severity and relationship to study treatments drug of AE
- Time to progression, (TTP), disease control rate, and survival rates over time up to 24 weeks, (DCR), overall survival (OS),) and event free survival (EFS) over time up to 24 weeks:
* Time to progression is defined as the time from randomization to time of objective disease progression.
* Disease control rate is defined as the percentage of patients who achieved disease control overtime following randomization. Disease control at 24 weeks is defined as a best objective response of Complete Response (CR), Partial (PR) or stable disease (SD ≥ 24) per RECIST criteria (version 1.1) (MRI/CT scan every 8 weeks or sooner if clinically indicated).
* Objective response rate defined as complete or partial response (CR or PR) per RECIST criteria (version 1.1) (MRI/CT scan every 8 weeks or sooner if clinically indicated)
* Overall survival defined as the time elapsed between randomization and death from any cause
* Event free survival defined as the time elapsed between randomization and disease progression, or treatment stop/delayed from toxicity reason, or death from any cause
Patients who are alive without disease progression by the clinical cut-off will be censored at the dates of their last tumor evaluation.
- Pharmacokinetic (PK) / pharmacodynamic parameters evaluation of ERY001 including
* Pharmacokinetic parameters: Blood activity of free, total, plasmatic and encapsulated L-asparaginase
* Pharmacodynamic parameters: Plasmatic concentrations of amino-acids (asparagine, aspartate, glutamine, and glutamate; ); Percentage of patient presenting with asparagine depletion at different time points (i.e. ≤ 2µM);
* Percentage of deamination compared to baseline levels;
* Immunogenicity: titers of Anti-L-asparaginase antibodies
PK/PD parameters will be measured at different time points: prior each administration of ERY001 and then each day of chemotherapy administration. Anti-L asparaginase antibodies will be measured prior each administration of ERY001.
- Tumor response evaluation by one or several tumor (bio)markers (CEA and CA 19.9) in different groups measured at baseline and at end of every 8 weeks of chemotherapy
- Compliance to treatments: Ratio of performed/planned treatments injections over the total mean duration of treatment, ratio of performed/planned doses over the total duration of treatment.
- Tumor response according ASNS level.
- Patient quality of life measured by EORTC patient survey (QLQ-C30) with specific module Panc 26.
Exploratory endpoints:
- PFS rate of ASNS 2-3 patients with ERY001 at week 16;
- KRAS mutational status;
- Circulating tumor DNA quantification. Variations of circulating tumor DNA will be also correlated with radiological evaluations and clinical outcome
- Genetic alterations within other frequently mutated genes in pancreatic cancer (SMAD4, P16);
- To better define the tumor response by using new imaging methods such as diffusion and DCE MRI, CEUS and/or 18f-FDG PET, according to Chun and Choi criteria |
