NCT07303283

Brief Summary

This is a phase 2, multicentre, open-label, randomised, controlled trial with a parallel-group design. The study aims to compare the efficacy and safety of Becotatug Vedotin and capecitabine as an adjuvant therapy in patients with high-risk locoregionally advanced nasopharyngeal carcinoma (NPC).

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically confirmed non-keratinizing nasopharyngeal carcinoma(WHO II/III).
  • Original clinical staged as TanyN2-3M0 or T4N1M0 (according to AJCC 9th edition), with no evidence of distant metastasis.
  • ECOG performance status ≤1.
  • Induction and concurrent chemoradiotherapy with the recommended regimen have been completed.
  • No later than 6 weeks after the completion of the last radiotherapy treatment.
  • Adequate hematologic (neutrophil count \> 1.5×10\^9/L, hemoglobin \> 90g/L and platelet count \> 100×10\^9/L), hepatic (alanine aminotransferase, aspartate aminotransferase ≤ 1.5×ULN, bilirubin ≤ 1.5×ULN, alkaline phosphatase \< 2.5×ULN) and renal function (creatinine clearance \> 50 ml/min)
  • Patients must be informed of the investigational nature of this study and give written informed consent.
  • Women of childbearing potential (WOCBP) who are sexually active must be willing to adhere to effective contraception during treatment and for 1 year after the last dose of the study drug. Men who are sexually active with WOCBP must be willing to adhere to effective contraception during treatment and for 1 year after the last dose of the study drug.

You may not qualify if:

  • Patients who could not tolerate or were allergic to Becotatug Vedotin.
  • Patients with severe chronic or active infection that must be treated with systemic antibacterial, antifungal, or antiviral therapy before randomization, including but not limited to tuberculosis infection.
  • Prior malignancy except adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer.
  • Pregnancy or lactation (consider pregnancy test in women of child-bearing age and emphasize effective contraception during the treatment period).
  • Interstitial lung disease or pneumonia requiring oral or intravenous steroid therapy within 1 year.
  • Patients who are known to be intolerant or sensitive to any therapeutic agents.
  • Any severe intercurrent disease, which may bring unacceptable risk or affect the compliance of the trial, for example, unstable cardiac disease requiring treatment, renal disease, chronic hepatitis, diabetes with poor control (fasting plasma glucose \> 1.5×ULN), and emotional disturbance.
