NCT07176182

Brief Summary

This study is a prospective, multicenter, open-label, randomized controlled Phase II clinical trial enrolling patients with locally advanced rectal cancer who tested positive for YWHAB (tyrosine 3-monooxygenase/tryptophan 5-monooxygenase-activating protein β) prior to surgery. The trial aims to evaluate the efficacy of combining the mFOLFOX chemotherapy regimen with citrus flavonoid tablets (Aimilang) for neoadjuvant (preoperative) treatment. Treatment Regimen 4-6 cycles preoperatively, with each cycle lasting 14 days. Translated with DeepL.com (free version) Oxaliplatin: 85 mg/m² via 180-minute intravenous infusion on Day 1. Leucovorin: 400 mg/m² via 120-minute intravenous infusion on Day 1. 5-Fluorouracil: 2400 mg/m² via continuous intravenous infusion over 46 hours. Citrus flavonoid tablets (Aimailang) : 500 mg orally twice times daily (Days 1-14), administered with or without the chemotherapy regimen (depending on group assignment). Key Trial Design Features Dose Adjustments: Permitted during the trial based on patient tolerance. Discontinuation Criteria: Patients with disease progression during neoadjuvant therapy will cease study treatment and proceed to surgery or alternative therapies per local guidelines. Surgery may be initiated early if patients cannot tolerate the planned 6 cycles of neoadjuvant therapy. Patients receiving non-protocol anticancer therapies preoperatively will be withdrawn from the study. Postoperative Management: Post-treatment plans (e.g., continuation of mFOLFOX + Aimailang) are determined by the investigator. Control Group Restriction: Patients in the control arm are not permitted to self-administer citrus flavonoid tablets (Aimailang) during the trial. Any requirement for this medication must be discussed with the treating physician, who will decide on alternative therapies or trial withdrawal.

Outcome Measures

Primary Outcomes (1)

  • Tumor downstaging rate (to ypTNM stage 0-I)

    The proportion of patients with locally advanced rectal cancer who, after receiving neoadjuvant chemotherapy with mFOLFOX or mFOLFOX plus Citrus flavonoid tablets (Aimailang), were downstaged to ypTNM stage 0-I based on postoperative surgical specimens.

    Perioperative,2 weeks after surgery

EXPERIMENTAL

This trial evaluated a combination regimen of mFOLFOX chemotherapy with citrus flavonoid tablets (Aimailang) for both neoadjuvant (preoperative) and postoperative adjuvant treatment. Treatment Regimen Preoperative (4-6 cycles), each 14-day cycle included. Oxaliplatin: 85 mg/m² intravenous infusion on Day 1, administered over 180 minutes. Calcium folinic acid: 400 mg/m² intravenous infusion on Day 1, over 120 minutes. 5-Fluorouracil: 2400 mg/m², continuous intravenous infusion over 46 hours on Day 1. Citrus Flavonoid Tablets (Aimailang): 500 mg, orally twice daily (Days 1-14), may be used in combination with the chemotherapy regimen or alone (depending on grouping).

  • Age 18-75 years at the time of informed consent.
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 (Appendix 3).

  • Adequate organ function with screening laboratory parameters meeting the following criteria:
  • White blood cell count ≥ 3 × 10⁹/L
  • Absolute neutrophil count ≥ 1.5 × 10⁹/L
  • Platelet count ≥ 75 × 10⁹/L
  • Total bilirubin ≤ 1.5 × upper limit of normal (ULN)
  • Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 × ULN
  • Serum creatinine ≤ 1.5 × ULN
  • Females of childbearing potential must have a negative serum pregnancy test within 3 days prior to initiation of study treatment and agree to use a highly effective, medically acceptable contraceptive method (e.g., intrauterine device, combined oral contraceptives, barrier methods) throughout the study and for 3 months after the last study drug administration.
