HER2発現性シスプラチン不適格上部尿路尿路上皮癌の術後補助療法におけるDisitamab Vedotinプラス放射線療法 (LUXUS41)
A Randomized, Prospective, Multicenter, Phase III Study of Disitamab Vedotin Plus Radiotherapy as Adjuvant Treatment for HER2-Expressing Cisplatin-Ineligible Upper Tract Urothelial Carcinoma
This randomized, open-label, multicenter phase III study is designed to compare disitamab vedotin plus radiotherapy with gemcitabine plus carboplatin as adjuvant treatment in patients with HER2-expressing upper tract urothelial carcinoma after radical nephroureterectomy (RNU). Eligible patients must have postoperative pathologic stage pT3-pT4N0M0 or pTanyN+M0, HER2 expression defined as immunohistochemistry (IHC) 1+, 2+, or 3+, and be cisplatin-ineligible. Patients will be randomized in a 2:1 ratio to receive disitamab vedotin plus radiotherapy or gemcitabine plus carboplatin. The primary endpoint is 3-year disease-free survival. Secondary endpoints include overall survival, metastasis-free survival, local recurrence-free survival, bladder recurrence-free survival, incidence of adverse events, and patient-reported quality of life.

説明
Inclusion Criteria:
- Aged 18 years or older.
- Histologically confirmed upper tract urothelial carcinoma (UTUC) after radical nephroureterectomy (RNU).
- Postoperative pathologic stage pT3-pT4N0M0 or pTanyN+M0.
- HER2 expression confirmed by immunohistochemistry (IHC 1+, 2+, or 3+).
- Cisplatin-ineligible, defined as meeting at least one of the following criteria: ECOG performance status 2; creatinine clearance <60 mL/min; CTCAE grade 2 or higher hearing loss; CTCAE grade 2 or higher peripheral neuropathy; or New York Heart Association (NYHA) class III heart failure.
- Adequate organ function.
- Expected survival of at least 6 months.
Exclusion Criteria:
- History of other active malignancies, except for adequately treated malignancies with low risk of recurrence.
- Prior systemic antitumor therapy before study treatment, or unresolved toxicities from prior therapy.
- Known hypersensitivity to disitamab vedotin, related agents, or any component of the study treatment.
- Severe active infection.
- Not adequately recovered from surgery.
- Pregnant or breastfeeding women.
- Any other condition that, in the investigator's judgment, makes the patient unsuitable for participation in the study.

実験的：Disitamab Vedotin Plus Radiotherapy
Participants in this arm will receive disitamab vedotin plus radiotherapy as adjuvant treatment after radical surgery for HER2-expressing,cisplatin-ineligible upper tract urothelial carcinoma. |
Disitamab vedotin 2.0 mg/kg (maximum 120 mg) will be administered intravenously every 2 weeks for 12 cycles as adjuvant treatment after radical surgery. Adjuvant radiotherapy will be delivered to the regional lymphatic drainage area at 45-50 Gy in 25 fractions over 5 weeks. Suspicious lymph nodes will receive 62.5 Gy in 25 fractions over 5 weeks. |
|
アクティブコンパレータ：Gemcitabine Plus Carboplatin
Participants in this arm will receive gemcitabine plus carboplatin as adjuvant treatment after radical surgery for HER2-expressing cisplatin-ineligible upper tract urothelial carcinoma. |
Gemcitabine 1000 mg/m² will be administered on Days 1 and 8 of each 21-day cycle for 4 to 6 cycles as adjuvant treatment after radical surgery. Carboplatin will be administered intravenously on Day 1 of each 21-day cycle at a target AUC of 4.5 to 5 for 4 to 6 cycles as adjuvant treatment after radical surgery. |
