Interventions

  • Durvalumab (MEDI4736) — DRUG
    6 cycles of mFOLFOX6 (oxaliplatin, leucovorin and fluorouracil) followed by long course chemoradiotherapy (50.4 Gy together with capecitabine) followed by surgery. Patients will receive durvalumab 1500 mg every 4 weeks during induction chemotherapy, chemoradiotherapy and waiting period until surgery.

Study Details

The addition of durvalumab to total neoadjuvant therapy (TNT) in locally advanced rectal cancer may improve the pathological complete response rate. The induction platinum-based chemotherapy may increase the neoantigen formation together with the chemoradiotherapy period. Starting durvalumab during the first chemotherapy session and continuing during the 6-week period of chemoradiotherapy could change and create the needed environment to increase the efficacy of durvalumab in this setting. Additionally, the 8-12 week rest period from the end of the chemoradiotherapy and the radical surgery, treatment with durvalumab may continue improving the response and outcome of patients without jeopardizing the surgery (which needs this period out of chemotherapy and radiotherapy to avoid postoperative complications, but not for anti-PDL-1 therapy). Patients will be included following inclusion/exclusion criteria in a prospective, non-randomized, open label, single arm phase II study to receive 6 cycles of mFOLFOX6 (oxaliplatin, leucovorin and fluorouracil) followed by long course chemoradiotherapy (50.4 Gy together with capecitabine) followed by surgery. Patients will receive durvalumab 1500 mg every 4 weeks during induction chemotherapy, chemoradiotherapy and waiting period until surgery.
