The Combination of Adebrelimab and TP Regimen for Neoadjuvant Therapy in Patients With Stage IVB Oral Squamous Cell Carcinoma
Status: Recruiting

The goal of this [type of study:clinical trial] is to [learn about] in [Clinical IVB stage oral squamous cell carcinoma patients]. The main question it aims to answer are:

• [Observing the effectiveness and safety of the combination of Adebrelimab and TP regimen in neoadjuvant therapy for clinical IVB stage oral squamous cell carcinoma patients] Participants will [Received treatment with Adebrelimab combined with TP regimen, followed by surgery after 2 cycles of neoadjuvant therapy. After surgery, radiotherapy and chemotherapy combined with immunotherapy were chosen based on the patient&#39;s condition, with a total follow-up of two years.].

Allow the use of hormones for routine chemotherapy pretreatment without the need for dose adjustment. Other special circumstances require communication with the researcher. In the absence of active autoimmune diseases, it is allowed to inhale or locally use steroids and adrenal cortex hormone replacement with a dose greater than 10mg/day of prednisone efficacy dose; Individuals who have received anti-tumor vaccines or have received live vaccines within 4 weeks prior to the first administration of the investigational drug; Having undergone major surgery or severe trauma within 4 weeks prior to the first use of the investigational drug; Patients who have previously received treatment with paclitaxel drugs; The toxicity of previous anti-tumor treatments has not recovered to ≤ CTCAE 5.0 level 1 (excluding hair loss) or the level specified by the inclusion/exclusion criteria; A history of active autoimmune diseases and autoimmune diseases (such as interstitial pneumonia, colitis, hepatitis, pituitary inflammation, vasculitis, nephritis, hyperthyroidism, hypothyroidism, including but not limited to the above diseases or syndromes); Excluding patients with vitiligo or childhood asthma/allergies who have already recovered and do not require any intervention in adulthood; Autoimmune mediated hypothyroidism treated with stable doses of thyroid replacement hormone; Type I diabetes with a stable dose of insulin; Have a history of immune deficiency, including HIV test positive, or have other acquired or congenital immune deficiency diseases, or have a history of organ transplantation and allogeneic bone marrow transplantation, or active hepatitis (hepatitis B reference: HBV DNA test value exceeds 500 IU/ml or 2500 copies/mL); The subjects have uncontrolled cardiovascular clinical symptoms or diseases, including but not limited to: (1) NYHA grade II or above heart failure; (2) Unstable angina pectoris; (3) Have experienced myocardial infarction within one year; (4) Clinically significant supraventricular or ventricular arrhythmias that have not been clinically intervened or are still poorly controlled after clinical intervention; Serious infections (CTCAE 5.0&amp;amp;gt;Level 2) occurred within 4 weeks prior to the first use of the study drug, such as severe pneumonia, bacteremia, and infection complications that require hospitalization treatment; Baseline chest imaging examination suggests the presence of active pulmonary inflammation, symptoms and signs of infection within 2 weeks prior to the first use of the study drug, or the need for oral or intravenous antibiotic treatment, excluding prophylactic use of antibiotics; History of interstitial lung disease (excluding radiation pneumonia and non infectious pneumonia that have not been treated with steroids); Patients who have been diagnosed with active pulmonary tuberculosis infection through medical history or CT examination, or have a history of active pulmonary tuberculosis infection within one year before enrollment, or have a history of active pulmonary tuberculosis infection more than one year before but have not received formal treatment; Diagnosed with any other malignant tumor within the 5 years prior to the first use of the investigational drug, excluding malignant tumors with low risk of metastasis and mortality (5-year survival rate&amp;amp;gt;90%), such as basal cell or squamous cell skin cancer or cervical carcinoma in situ that has been adequately treated; Pregnant or lactating women; According to the researcher&amp;amp;#39;s judgment, there are other factors that may cause the subject to be forced to terminate the study midway, such as other serious illnesses (including mental illness) requiring concurrent treatment, severe abnormalities in laboratory test values, family or social factors, which may affect the safety of the subject or the collection of trial data. - HealthyVolunteers: No - Gender: All - MinimumAge: 18 Years - MaximumAge: 75 Years - StdAgeList: Adult, Older Adult
