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.
The age is 18~75 years old (including the critical value), regardless of gender.
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.
Phase II cohort 3, cohort 4, cohort 5: Histologically confirmed nasopharyngeal carcinoma, stage IVb or recurrent nasopharyngeal carcinoma that is not suitable for local treatment according to the TNM of AJCC nasopharyngeal carcinoma in the 8th edition of 2017; In the past, they only received ≤2 line therapy for recurrent and metastatic nasopharyngeal carcinoma.
According to the researcher's judgment, the chemotherapy in this experiment is applicable.
Received other unlisted clinical research drugs or treatments within 4 weeks before using the research drugs.
The adverse reactions of previous anti-tumor treatments have not recovered to NCI CTCAE 5.0 grade evaluation ≤1 grade or the relevant provisions of the selection criteria (except for the toxicity that the researchers judged to have no safety risk, such as alopecia, grade 2 peripheral neurotoxicity, hypothyroidism stabilized by hormone replacement therapy, etc.).
It is known that it has hypersensitivity to any antibody drugs (NCI CTCAE 5.0 rating is ≥3), or it has hypersensitivity to research drugs, active ingredients or inactive excipients of chemotherapy schemes.
Have received major surgery (excluding puncture biopsy), major trauma or need to undergo elective surgery during the trial within 4 weeks before the first use of the study drug.
