A Pilot Study of Ciprofloxacin Plus Gemcitabine and Nab-Paclitaxel Chemotherapy in Patients With Metastatic Pancreatic Ductal Adenocarcinoma.

August 19, 2020 updated by: National University Hospital, Singapore
This is a single-center, pilot study evaluating the addition of Ciprofloxacin (study drug) to standard-of-care gemcitabine and nab-paclitaxel chemotherapy in treatment-naïve metastatic PDAC patients. Patients who are recommended gemcitabine and nab-paclitaxel chemotherapy as a standard-of-care by their treating physician will be offered to participate in this study.

Detailed Description

Oral ciprofloxacin (study drug) will be administered twice a day throughout each 28-day cycle of gemcitabine and nab-paclitaxel chemotherapy. The patient will start taking ciprofloxacin from the evening of day 1 of chemotherapy and end on the morning of day 29 of each cycle.

Ciprofloxacin tablets should be taken in the morning and evening at about the same time each day. Swallow the tablet whole. Do not split, crush or chew the tablet. Ciprofloxacin can be taken with or without food

With each study visit, the physician will prescribe 1-month supply of oral ciprofloxacin to be taken home and self-administered by the patient. The physician will have to indicate "pancreatic cancer microbiome study" on the remarks column for each cycle oral ciprofloxacin is ordered.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Antitumor Effect - Solid Tumors
Time Frame: 4 years

Patients are be re-evaluated for response every 8-12 weeks (±10 days), per standard-of-care.

Response and progression will be evaluated in this study using the international criteria proposed by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1). Changes in the largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes are used in RECIST.
