Brief summary: Phase II: To evaluate the safety and tolerability of IAE0972 combined with chemotherapy selected by doctors for R/M HNSCC/NPC after failure or progress of ≤2-line system therapy, and to determine the MTD of combined therapy.

Phase III: According to the RECIST 1.1, the effectiveness of IAE0972 combined with chemotherapy regimen chosen by doctors compared with placebo plus chemotherapy regimen chosen by doctors was evaluated through OS in patients with R/M NPC who failed or progressed after treatment with ≤2-line system.

Detailed description: The Phase II is the dose escalation study of IAE0972 combined with the chemotherapy chosen by doctors, aiming at evaluating the safety, tolerance and preliminary effectiveness for patients with R/M HNSCC/NPC;Phase III aims to evaluate the effectiveness and safety of IAE0972+ doctors' chemotherapy compared with doctors' chemotherapy in patients with R/M NPC who have failed or progressed after treatment with ≤2-line system through OS.In the study, the adverse events and reactions were evaluated by clinical observation, vital signs monitoring and laboratory examination, and related samples such as PK and ADA were collected. Taking RECIST 1.1 as the tumor evaluation standard, after the first infusion of the study drug, every two cycles (±7 days, before the next cycle of administration, and the day of administration in this cycle is defined as D1 of the current cycle), the subjects were evaluated for tumor until the disease progressed, new anti-tumor treatment was started, the researchers judged that it was not suitable to continue to participate (such as intolerable adverse reactions), lost the visit, and voluntarily withdrew.When the subject withdraws from or terminates the treatment (+7 days), the subject should be visited before starting the new anti-tumor treatment (except death and lost visit), and relevant laboratory tests and ADA sample collection should be carried out; After that, their OS was followed up by telephone every 12 weeks (±7 days) until they were lost or died.

Eligibility criteria: Inclusion Criteria:

Phase II cohort 1, cohort 2: locally advanced squamous cell carcinoma of the head and neck which only occurred in the oral cavity, oropharynx, hypopharynx and larynx after histological diagnosis or had no indication of radical local treatment; In the past, I only received ≤2 line therapy for recurrent and metastatic head and neck squamous cell carcinoma.

4. According to the researcher's judgment, the chemotherapy in this experiment is applicable.
5. According to the RECIST 1.1 standard, there is at least one measurable lesion (tumor lesions located in previous radiotherapy areas or other local regional treatment sites are generally not regarded as measurable lesions, unless the lesions make clear progress or persist after radiotherapy for three months).

     * Renal function: Cr≤1.5 times ULN; If the creatinine is more than 1.5 times ULN, the CCR should be ≥ 50 ml/min (calculated according to Cockcroft-Gault formula);

       * Coagulation function: INR≤1.5 times ULN, APTT≤1.5 times ULN, and INR and APTT≤2.5 times ULN for patients with liver metastasis or liver cancer.
9. Qualified fertile subjects (male and female) must agree to use reliable contraceptive methods (hormone or barrier method or abstinence) with their partners during the trial and at least 6 months after the last medication; The blood pregnancy test of female subjects of childbearing age must be negative within 7 days before the first use of the study drug.
