About this trial

This study is a randomized, open-label, multicenter phase III trial designed to systematically evaluate the efficacy and safety of perioperative neoadjuvant and adjuvant therapy with Becotatug vedotin in combination with PD-1 inhibitor versus PD-1 inhibitor alone in patients with EGFR-positive, CPS ≥ 1 resectable locally advanced head and neck squamous cell carcinoma .

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Untreated, histologically confirmed head and neck squamous cell carcinoma (oral cavity, oropharynx, hypopharynx, or larynx), EGFR-positive, CPS ≥ 1, with clinical stage (AJCC 8th edition): p16-positive oropharynx: Stage III (T4N0-2M0); p16-negative oropharynx: Stage III or IVA; larynx/hypopharynx/oral cavity: Stage III or IVA;

Eligible for curative-intent surgery as determined by the surgeon;

Age: 18 to 75 years;

Disqualifiers

Pregnant or breastfeeding women.

History of allergy to PD-1 inhibitors.

History of other malignancies within the past 5 years or at enrollment, with the exception of cured basal cell carcinoma of the skin, carcinoma in situ of the cervix, and thyroid papillary tumors.

Residual toxicity from prior anti-tumor therapy (including immunotherapy, targeted therapy, chemotherapy, or radiotherapy, etc.) other than alopecia, fatigue, and grade 2 hypothyroidism, or clinically significant laboratory abnormalities greater than grade 1 (CTCAE v5.0).

Treatments tested in this trial

  • Neoadjuvant and Adjuvant Becotatug Vedotin

    Drug

    Neoadjuvant therapy with Becotatug Vedotin (Day 1, Q3W, 2 cycles); Adjuvant therapy after radiotherapy with Becotatug Vedotin ( Day 1, Q3W, for a total of 12 cycles).

  • Neoadjuvant and Adjuvant Immunotherapy

    Drug

    Neoadjuvant immunotherapy with pucotenlimab (200mg, Day 1, Q3W, 2 cycles); Adjuvant immunotherapy duiring and after radiotherapy with pucotenlimab (200mg, Day 1, Q3W, for a total of 15 cycles).

  • Surgery

    Procedure/Surgery

    Radical surgery performed 3-4 weeks after neoadjuvant therapy, following a re-evaluation of surgical indications by the surgeon.

  • Adjuvant Radiotherapy

    Radiation

    Radiotherapy is initiated 4-6 weeks after surgery. For the low-risk group, a total dose of 60 Gy in 30 fractions is delivered using intensity-modulated radiation therapy (IMRT). For the high-risk group, 66 Gy in 33 fractions is prescribed, or 70 Gy in 35 fractions for residual lesions, also using IMRT.

  • Adjuvant Cisplatin

    Drug

    High-risk group:Cisplatin 100 mg/m² is administered via intravenous infusion on Day 1 of every 21-day cycle during radiotherapy, for a total of 3 cycles.
