Detailed Description
-----------------
This is a phase 2, open-label, umbrella study, with the purpose to evaluate the therapeutic efficacy and safety of chemoradiotherapy in combination with immunotherapy and/or targeted treatment in high-risk locoregionally advanced nasopharyngeal carcinoma. The specific grouping of patients' depends on the SYSUCC immune subtyping based on 100+ gene panel testing. The molecular subgroups include the Active, Evaded and non-Immune Subtypes. New treatment arms may be added and/or existing treatment arms may be closed during the study course on the basis of ongoing efficacy and safety as well as the current treatments available.

For patients older than 50 years with a smoking history, normal lung function are required. Patients with abnormal ECG and/or a history of vascular disease (but not meeting the exclusion criteria listed in the exclusion criteria 7) need further testing and require normal results of myocardial function and color Doppler ultrasound. Normal liver and kidney function: total bilirubin ≤ 1.5 × upper limit of normal (ULN); alanine transaminase and aspartate transaminase ≤ 2.5 × ULN; alkaline phosphatase ≤ 2.5 × ULN; creatinine clearance rate ≥ 60 ml/min; Patients must sign informed consent and be willing and able to comply with the requirements of visits, treatment, laboratory tests and other research requirements stipulated in the research schedule; Subjects with pregnancy ability must agree to use reliable contraceptive measures from screening to 1 year after treatment. Exclusion Criteria: Hepatitis B virus surface antigen (HBsAg) positive and HBV DNA > 1×10E3 copies/ml; anti-hepatitis C virus positive; Anti-human immunodeficiency virus (HIV) positive or diagnosed with acquired immune deficiency syndrome (AIDS); Active tuberculosis: active tuberculosis in the past 1 year should be excluded regardless with treatment; history of active tuberculosis over 1 year should be excluded except that previous regulatory anti-tuberculosis treatment is proved; Active, known or suspected autoimmune disease (including but not limited to uveitis, enteritis, hepatitis, pituitary, nephritis, vasculitis, hyperthyroidism, hypothyroidism and asthma requiring bronchiectasis). Exceptions are type I diabetes mellitus, hypothyroidism requiring hormone replacement therapy, skin disorders requiring no systemic treatment (such as vitiligo, psoriasis or alopecia); Previous interstitial lung disease or pneumonia requiring oral or intravenous steroid therapy; Chronic treatment with systemic glucocorticoid (dose equivalent to or over 10 mg prednisone per day) or any other form of immunosuppressive therapy. Subjects who used inhaled or topical corticosteroids were eligible; Uncontrolled heart disease, for example: 1) heart failure (NYHA level ≥ 2); 2) unstable angina; 3) myocardial infarction in past 1 year; 4) supraventricular or ventricular arrhythmia requiring treatment or intervention; Pregnant or lactating women (pregnancy test should be considered for women with sexual life and fertility); Previous or concurrent with other malignant tumors, except for adequately treated non-melanoma skin cancer, cervical carcinoma in situ and thyroid papillary cancer; Allergy to macromolecular protein preparations, or any component of the intervention drugs; Active infection requiring systemic treatment; History of organ transplantation; History of psychotropic disease, alcoholism or drug abuse; other situation assessed by the investigators that may compromise the safety or compliance of patients, such as serious disease requiring timely treatment (including mental illness), severe laboratory abnormalities, or family-social risk factors.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Failure-free survival (FFS) | Failure-free survival is measured from day of diagnosis until treatment failure, death from any cause, or last follow-up visit, whichever occurred first | 3-year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall survival (OS) | Overall survival is measured from day of diagnosis until death due to any cause or the latest known date alive | 3-year | 
| Distant failure-free survival (DFFS) | Distant failure-free survival is measured from day of diagnosis until distant metastasis | 3-year | 
| Incidence rate of investigator-reported adverse events (AEs) | Analysis of investigator-reported adverse events (AEs) are based on treatment-related AEs (trAEs) and immune-related AEs (irAEs), and all-grade AEs and grade 3-4 AEs. AEs are evaluated by investigators according to the Common Terminology Criteria for Adverse Events, version 5.0 | 3-year | 
| Incidence rate of patient-reported adverse events (AEs) | Analysis of patient-reported adverse events (AEs) are based on treatment-related AEs (trAEs) and immune-related AEs (irAEs), and all-grade AEs and grade 3-4 AEs. AEs are evaluated by patients themselves | 3-year |
