Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Dalpiciclib+cetuximab

Arm Description

The dosing regimen for cetuximab combined with dalpiciclib is: the starting dose of cetuximab is 400 mg/m2, titrated over 120 minutes, and the titration rate should be limited to 5 ml/min. A maintenance dose of 250 mg/m2, titrated over not less than 60 minutes, with pretreatment with H1 receptor blocker desensitization prior to dosing, administered once weekly. The recommended dose of dalpiciclib is 150 mg once daily for 21 days, followed by 7 days of discontinuation (3/1 dosing regimen) for a 28-day treatment cycle. Take the drug at approximately the same time each day. If the patient vomits or misses a dose, the dose should not be made up that day. The next dose should be taken as usual. Subjects will continue treatment with cetuximab in combination with dalpiciclib until termination criteria are met.

Outcomes

Primary Outcome Measures

objective response rate
ORR was defined as the percentage of participants in the analysis population who have a Complete Response (CR: disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1.

Secondary Outcome Measures

overall survival
OS was defined as the time from enrollment to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up.
Progression Free Survival Per RECIST 1.1
PFS was defined as the time from enrollment to the first documented PD per RECIST 1.1, or death due to any cause, whichever occurred first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum had to demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions was also considered PD
Number of Participants Experiencing an Adverse Event (AE).
An AE was defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which did not necessarily have to have a causal relationship with this treatment. An AE could therefore be any unfavourable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a pre-existing condition that was temporally associated with the use of the Sponsor's product was also an AE. The number of participants that experienced at least one AE was reported for each treatment arm.
Quality of life#EORTC QLQ-C30 scale#
The EORTC-QLQ-C30 is a 30-item questionnaire developed to assess the quality of life of cancer patients. Participant responses to the GHS question "How would you rate your overall health during the past week?" (Item 29) and the QoL question "How would you rate your overall quality of life during the past week?" (Item 30) were scored on a 7-point scale (1=Very Poor to 7=Excellent).

5. Study Description

Brief Summary
This study is the first clinical study in PD-1 resistant patients with head and neck squamous cell carcinoma with drugs targeting EGFR signaling pathway combined with CDK4/6 inhibitors, which explores the new combination therapies urgently needed in clinical practice and lays a foundation for subsequent studies, with important scientific research significance and clinical value.
Detailed Description
Head and neck cancer is the sixth most common cancer in the world, with more than 550,000 incidences and 300,000 deaths per year worldwide. more than 95% of head and neck cancers are squamous cell carcinomas, and head and neck squamous cell carcinoma (HNSCC) has a devastating and HNSCC affects the quality of life of patients by damaging and affecting their appearance and basic physical, sensory and speech functions. Due to the difficulty of early detection, more than 60% of head and neck squamous cell carcinoma patients are already at locally advanced stage when detected, and the prognosis of locally advanced head and neck carcinoma is poor, and even after receiving aggressive treatment, it is prone to local recurrence and distant metastasis after treatment. About 25% of patients with squamous head and neck cancer are associated with human papillomavirus (HPV) infection, of which the most common subtype is HPV 16, accounting for more than 80% of all HPV-induced head and neck cancers. HPV infection suppresses the function of oncogenes TP53 and RB, and promotes immune escape and promote the development of head and neck cancer. In China, more than 70% of head and neck squamous carcinomas are not associated with HPV infection, and compared with HPV-associated HNSCC, HPV-negative HNSCC has a lower response rate to treatment and the overall prognosis of patients is worse. Head and neck squamous cell carcinoma has a high rate of Treg cell as well as NK cell infiltration in the tumor microenvironment, forming an immunosuppressive tumor microenvironment and is a group of malignancies with high immunodeficiency. Studies have shown high levels of PD-L1 expression in tumor tissue in 46%-100% of HNSCC. Therefore, blockade of immune checkpoint inhibitors represented by PD-L1/PD-1 is a theoretically feasible therapeutic approach for the treatment of HNSCC. The results of previous clinical trials of immunotherapy in patients with recurrent or metastatic head and neck squamous carcinoma showed that anti-PD-1 antibodies led to durable remission and improved survival in patients with either first- or second-line therapy. The KEYNOTE-048 study confirmed that pembrolizumab in combination with chemotherapy prolonged overall survival in patients with recurrent or metastatic head and neck squamous carcinoma and in 2021 recommended by CSCO guidelines as a first-line expert recommendation for the first-line treatment of recurrent or metastatic head and neck squamous carcinoma (Level of Evidence 1A). However, patients with recurrent or metastatic head and neck squamous carcinoma after failure of first-line applied anti-PD-1 therapy enter second-line therapy The current guideline recommended second-line treatment regimens are cetuximab, afatinib or methotrexate, but the overall prognosis of patients is poor, the drug response rate is not high, the highest objective remission rate reported in the literature is only 13%, and the time to tumor progression is only 2.3 months, therefore, exploring new second-line treatment options for patients with recurrent or metastatic head and neck squamous carcinoma after failure of anti-PD-1 therapy is a pressing clinical need. In addition, the results of previous clinical trials showed that HPV-negative HNSCC had poorer sensitivity and prognosis to immunotherapy than HPV-associated HNSCC. In KEYNOTE-012, patients with HPV-positive HNSCC had higher objective remission (32% vs 14%) and progression-free survival (4 months vs 2 months) with pablizumab, and similar results were confirmed by KEYNOTE-055. Furthermore, in a meta-analysis of 11 studies, HPV-positive HNSCC patients showed a 1.29-fold higher response rate to immunotherapy and a twofold higher overall survival (11.5 months vs. 6.3 months) than HPV-negative HNSCC patients. There are a large number of ongoing clinical trials of combination targeted therapies and immunotherapies. The basic rationale supporting these combinations is that the two therapies combine different immunological and tumor biological mechanisms that enhance antitumor activity; in addition, some evidence suggests that targeted therapies can enhance certain aspects of the "cancer-immune cycle" (e.g., tumor antigenicity, T-cell initiation/transport/infiltration, etc.) to immunotherapy. In addition, it has been shown that targeted therapies can synergistically enhance certain aspects of the "cancer-immune cycle" (e.g., tumor antigenicity, T cell initiation/transport/infiltration, etc.) for immunotherapy. CDK4, one of the key cell cycle regulators, is involved in cell growth, proliferation, dormancy or apoptosis by binding to cell cycle protein D, which regulates the transition from G1 phase (pre-DNA synthesis) to S phase (DNA synthesis). In 2013, the US Food and Drug Administration (FDA) approved the CDK4 inhibitor Palbociclib as a breakthrough new drug for the treatment of advanced breast cancer, and the National Comprehensive Cancer Network (NCCN) guidelines recommend piperacillin in combination with an aromatase inhibitor as a first-line treatment option for HR+/HER2-advanced or metastatic breast cancer. Recent studies have found that CDK4 gene inhibition in combination with afatinib synergistically enhances the inhibition of the PI3k pathway in head and neck cancer cells, which in turn reduces tumor proliferation, providing a strong rationale for combination therapy. P16 deletion is a hallmark event in HPV-negative HNSCC patients, and p16 inactivation would lead to CDK4/6 hyperactivation, making CDK4/6 theoretically a potential target for HPV-negative HNSCC. Some progress has been made with CDK4/6 inhibitors in HPV-negative head and neck squamous carcinoma. In a multicenter, multicohort phase II clinical trial, cohort 1 enrolled in first-line treatment of platinum-resistant HPV-negative patients with recurrent/metastatic HNSCC, and cohort 2 enrolled in first-line treatment of cetuximab-resistant HPV-negative cohort 3 enrolled patients with cetuximab-resistant HPV-positive recurrent/metastatic oropharyngeal cancer, and all three groups received Palbociclib in combination with cetuximab, showing objective remission rates of up to 39% in cohort 1 and 19% in cohort 2, but only 4% in cohort 3, indicating that CDK4/6 inhibitors in combination with cetuximab has a promising application in the treatment of HPV-negative HNSCC. This clinical study involved dalpiciclib, which was developed by Jiangsu Hengrui Pharmaceutical Co. In December 2021, the State Drug Administration approved the drug in combination with fulvestrant for patients with recurrent or metastatic breast cancer with hormone receptor-positive, human epidermal growth factor receptor 2-negative disease progression after previous endocrine therapy through a priority review and approval process. Patients. Preclinical studies have shown that dalpiciclib has comparable in vivo efficacy and safety compared to its foreign counterparts. This study is also the first clinical study of a drug targeting CDK4/6 in combination with cetuximab for the treatment of HPV-negative head and neck squamous carcinoma after progression of PD-1 therapy in China, which is of great scientific significance and clinical value in exploring new combination therapies for HPV-negative patients, a population with poor clinical outcome, and laying the foundation for subsequent studies.
