De-escalation Radiation Strategy After NAC in Combination With ICI in LAHNSCC

Phase 1

Recruiting

• Conditions: Locally Advanced Head and Neck Squamous Cell Carcinoma
• Interventions: Drug: immunotherapy：pembrolizumab；chemo：albumin-bound paclitaxel and cisplatin

• Registration Number: NCT06572514
• Lead Sponsor: Ruijin Hospital

Brief Summary

This study is a single-arm exploratory study conducted in LAHNSCC. Eligible patients received two cycles of pembrolizumab immunotherapy in combination with albumin-bound paclitaxel and cisplatin induction chemotherapy, followed by definitive concurrent radiochemotherapy. Three months after the completion of radiotherapy, a follow-up examination was conducted, and salvage surgery or systemic therapy was performed as necessary based on the follow-up results.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
experimental arm	immunotherapy：pembrolizumab；chemo：albumin-bound paclitaxel and cisplatin	Eligible patients received two cycles of pembrolizumab immunotherapy in combination with albumin-bound paclitaxel and cisplatin induction chemotherapy, followed by definitive concurrent radiochemotherapy.

Primary Outcome Measures

Name	Time	Method
Progression-free survival (PFS)	1 year	Progression-free survival (PFS) (local-regional recurrence) is defined as the time from enrollment to the occurrence of local or regional lymph node recurrence or death for any reason.

Secondary Outcome Measures

Name	Time	Method
Quality of life	6 month and 1 year after the treatment	The assessment of quality of life is conducted using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire - Head and Neck Module (EORTC QLQ-H\&N 35), which includes eight domains: pain, swallowing, senses, speech, social eating, social contact, sexuality and single items. Each item is scored on a scale from 0 to 100. A high score for a functional scale or global QOL implies a high level of functioning or global QOL, whereas a high score for a symptom scale or single item implies a high level of symptoms.
Overall survival (OS)	3-year	Overall survival is defined as the time from enrollment to death for any reason
Clinical response rate	6 months	Clinical response is defined as the radiological evaluation of tumor regression as partial remission (PR) and complete remission (CR) on imaging assessment three months after the completion of treatment.
Safety(Grade 3-5 AE)	1-year	Safety is primarily assessed based on the probability of occurrence of Grade 3-5 adverse effects in different organs according to CTCAE 4.0 (including radiation-related injuries and adverse reactions to immunotherapy).
