Overview

This prospective, single-arm, exploratory, phase II study was designed to evaluate the efficacy and safety of Trilaciclib in reducing chemotherapy-induced neutropenia in patients with recurrent or metastatic head and neck squamous cell carcinoma. Eligible subjects screened by the inclusion and exclusion criteria will receive chemotherapy alone or combined with immune/targeted therapy and Trilaciclib for 4-6 cycles of continuous treatment. If the efficacy is not progressive after 4-6 cycles of treatment, the investigators can combine with Trilaciclib during immune and/or targeted maintenance therapy according to the specific conditions of the subjects until disease progression or intolerance. The efficacy of Trilaciclib will be evaluated by the incidence of grade ≥3 neutropenia during chemotherapy as the primary endpoint. After the progression of treatment, if the subjects were treated with chemotherapy for subsequent treatment and were considered to be able to use Trilaciclib according to the evaluation of the investigator, the use of treaclib could be considered until the subjects had disease progression again or were intolerant to treatment.

Head and neck squamous cell carcinoma (HNSCC) is the seventh most common malignant tumor in the world, accounting for 5% of all head and neck cancers in China. Among them, head and neck squamous cell carcinoma accounts for 90% of all head and neck malignant tumors, including nasopharyngeal carcinoma, oropharyngeal cancer, hypopharyngeal cancer, lip cancer, laryngeal cancer, nasal cavity cancer, paranasal sinus cancer, etc. Due to the complex anatomical and physiological structure of the head and neck, head and neck squamous cell carcinoma (HNSCC) is a highly heterogeneous group of malignant tumors. In all head and neck squamous cell carcinoma, more than 60% of patients are initially diagnosed as locally advanced (stage Ⅲ-Ⅳ, excluding M1). After comprehensive treatment, 40%-60% of patients will eventually develop local recurrence or distant metastasis, and the 5-year survival rate is less than 50%. Platinum-based chemotherapy remains the main treatment option. The first-line treatment is immune/targeted combination chemotherapy. Chemotherapy induced myelosuppression (CIM) is a common and important side effect in cancer treatment. 80% of chemotherapy drugs can cause bone marrow suppression, infection, bleeding, fatigue and other side effects, which seriously reduce the quality of life of patients, increase the economic burden, and may also lead to the reduction or delay of chemotherapy, which directly affects the anti-tumor efficacy of chemotherapy. In a retrospective analysis of patients with small-cell lung cancer, non-Hodgkin's lymphoma, head and neck cancer, and breast cancer by Yanli Li et al., 77.5% of patients had a high risk for Febrile neutropenia (FN) during chemotherapy. 18.8% of patients were hospitalized due to infection during the first course of treatment. For each additional day of continuous chemotherapy, the risk of hospitalization due to infection increased by 28% in patients with CIN 3/4, respectively, and the risk was 30% in patients with CIN 4. A study of 1111 patients with early-stage breast cancer treated with adjuvant chemotherapy from 13 large administrative, academic, and community practice centers showed that 61.2% of patients had delayed and reduced doses of chemotherapy due to: Neutropenia, 60.7% of patients with delayed chemotherapy and dose reduction caused by neutropenia will have neutropenia again, which seriously affects the survival and prognosis of patients. CIM is mainly reflected in erythropenia, neutropenia and thrombocytopenia, and the existing prevention methods for chemotherapy-induced bone marrow suppression have limitations. Recombinant human granulocyte coloby stimulating fator (G-CSF) can prevent febrile neutropenia, but may increase the risk of adverse reactions such as musculoskeletal pain. rhTPO and rhIL-11 can prevent chemotherapy-induced thrombocytopenia, but the operation is complicated and the adverse reactions are serious, especially cardiac toxicity and edema. Currently, there is no effective prevention for erythropenia. In the past, the traditional treatment for bone marrow suppression is not true bone marrow protection. G-CSF is also given after chemotherapy to stimulate the proliferation of surviving progenitor cells, and may even cause the exhaustion of bone marrow hematopoietic reserve function. Dose reduction and delayed administration of chemotherapy drugs are also common clinical measures to cope with CIM. These dose adjustments limit the relative dose intensity of the planned treatment and may reduce the potential benefit of patients. Safe, effective and easy to operate preventive drugs for myelosuppression, especially for thrombocytopenia and anemia, are currently unmet clinical needs. Trilaciclib is a highly potent, selective, and reversible CDK4/6 inhibitor that protects bone marrow by protecting hematopoietic stem/progenitor cells and lymphocytes during systemic chemotherapy. The proliferation and differentiation of progenitor cells are very dependent on the activity of CDK4/6. When they are exposed to appropriate doses of traC, they will be arrested in the G1 phase of the cell cycle. Therefore, intravenous administration of traC before chemotherapy can protect blood cells from cell cycle-toxic chemotherapy drugs. At the same time, treaclib can protect/enhance the immune system, make lymphocytes temporarily arrest, reduce the apoptosis of T lymphocytes and directly enhance the immune response. Changing the proliferation kinetics and composition of T cell subsets in the tumor is beneficial to enhance the effector function and improve the tumor microenvironment. This prospective, single-arm, exploratory, phase II study was designed to evaluate the efficacy and safety of Trilaciclib in reducing chemotherapy-induced neutropenia in patients with recurrent or metastatic head and neck squamous cell carcinoma. Eligible subjects screened by the inclusion and exclusion criteria will receive chemotherapy alone or combined with immune/targeted therapy and Trilaciclib for 4-6 cycles of continuous treatment. If the efficacy is not progressive after 4-6 cycles of treatment, the investigators can combine with Trilaciclib during immune and/or targeted maintenance therapy according to the specific conditions of the subjects until disease progression or intolerance. The efficacy of Trilaciclib will be evaluated by the incidence of grade ≥3 neutropenia during chemotherapy as the primary endpoint.After the progression of treatment, if the subjects were treated with chemotherapy for subsequent treatment and were considered to be able to use Trilaciclib according to the evaluation of the investigator, the use of treaclib could be considered until the subjects had disease progression again or were intolerant to treatment. The research unit of this clinical study is Shandong Cancer Hospital Affiliated to Shandong First Medical University, and it plans to enroll 30 patients with head and neck squamous cell carcinoma. This study protocol has been reviewed and approved by the ethics committee of Shandong Cancer Hospital Affiliated to Shandong First Medical University.
