Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is an integrated, open label, non-randomised, phase II trial of 2 neo-adjuvant regimens (FOLFOX-A and AG) assessing efficacy and toxicity with integrated translational work. The study is powered on testing a proposed DNA damage response deficient biomarker for responsiveness in patients treated with FOLFOX-A; patients being treated with AG are recruited concurrently. The study has a prospective safety assessment of neo-adjuvant chemotherapy and neo-adjuvant chemotherapy followed by chemoradiotherapy consisting of conventional radiotherapy with concomitant capecitabine. This safety assessment will include all patients (FOLFOX-A and AG)

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

FOLFOX-A

FOLFOX A arm (14-day cycle)

* nab-paclitaxel: 150mg/m2 IV over 30 minutes, day 1 (administered first).
* Oxaliplatin: 85mg/m2, IV over 2 hours, day 1.
* Folinic acid: 350mg flat dose, IV over 2 hours, day 1.
* Fluorouracil infusion:1200mg/m2/day, as a continuous IV infusion over 2 days, day 1 and day 2 (for a total dose of 2400mg/m2 over 46 hours or 48 hours as per local practice.)

Patients will also receive daily G-CSF as primary prophylaxis against neutropenic events for all cycles. This should be given as per local policy for chemotherapy regimens given every 14 days e.g. it may be started on day 4 for 7 days (preparation and dose should be given as per local policy).
