A Study of Live Biotherapeutic Product MRx0518 With Hypofractionated Radiation Therapy in Resectable Pancreatic Cancer

Phase 1
Terminated
Conditions
Pancreatic Cancer
Interventions
Radiation: Hypofractionated Preoperative Radiation
Registration Number
NCT04193904
Lead Sponsor
4D pharma plc
Brief Summary

This is a single center, open-label, phase I study to evaluate the safety and preliminary efficacy of MRx0518 with preoperative hypofractionated radiation in 15 patients with resectable pancreatic cancer.

Subjects will take MRx0518 daily for one week prior to the start of radiation therapy, throughout radiation and until surgical resection of the tumour.

Primary Outcome Measures
NameTimeMethod
To assess the safety of MRx0518 in combination with hypofractionated preoperative radiation through the collection of adverse eventsUp to 1 year post completion of radiation

Adverse events will be assessed as per CTCAE v5.0

Secondary Outcome Measures
NameTimeMethod
Major pathologic responseAt time of surgery

Major pathologic response is defined as \<5% viable cells in resected tumour specimen

Local Control6 months post radiation

Local control is defined as absence of progression at the primary site and will be assessed with imaging

Distant Control6 months post radiation

Distant control is defined as absence of progression at any site other than the primary site and will be assessed with imaging

Overall Survival (OS)12 months post radiation

OS is defined as the duration from the start of study treatment until death due to any cause

Margin statusAt time of surgery

The margin status of the tumour at the time of surgery will be assessed

Tumour infiltrating lymphocytes (TILs)Baseline to Surgery

Changes in TILs from optional baseline biopsy to resected tumour specimen will be assessed.

Progression Free Survival (PFS)12 months post radiation

PFS is defined as the duration from the start of study treatment until disease progression or death
