Results and lessons learnt from the WISTERIA phase I trial combining AZD1775 with cisplatin pre- or post-operatively in head and neck cancer.

ABSTRACT:

Background

Pre-clinical studies suggest AZD1775, a WEE1 kinase inhibitor, potentiates the activity of various chemotherapeutic agents.

Methods

WISTERIA was a prospective, parallel two-group, open-label, dose-finding, phase I clinical trial. Eligible patients had histologically confirmed oral, laryngeal, or hypopharyngeal squamous cell carcinoma, ECOG performance status 0/1, and aged ≥18-to-≤70 years. Primary outcomes were adverse events and defining recommended dose and schedule of AZD1775 in combination with cisplatin in pre-operative (Group A), or with cisplatin/radiotherapy in post-operative (Group B) patients. Dose determination was guided by a modified time-to-event continual reassessment method (mTITE-CRM).

Results

Between 30-Oct-2017 and 15-Jul-2019, nine patients were registered: Three into Group A and six into Group B. WISTERIA was closed early due to poor recruitment. Five dose-limiting toxicities (DLTs) were reported in four Group B patients. Seven serious adverse events were reported in four patients: One in Group A, and three in Group B. Three were related to treatment. No treatment-related deaths were reported.

Conclusions

WISTERIA did not complete its primary objectives due to poor recruitment and toxicities reported in Group B. However, use of the novel mTITE-CRM improved flexibility in reducing accrual suspension periods and should be considered for future trials in complex patient populations.

Project description:IntroductionPatients with head and neck squamous cell carcinoma with locally advanced disease often require multimodality treatment with surgery, radiotherapy and/or chemotherapy. Adjuvant radiotherapy with concurrent chemotherapy is offered to patients with high-risk pathological features postsurgery. While cure rates are improved, overall survival remains suboptimal and treatment has a significant negative impact on quality of life.Cell cycle checkpoint kinase inhibition is a promising method to selectively potentiate the therapeutic effects of chemoradiation. Our hypothesis is that combining chemoradiation with a WEE1 inhibitor will affect the biological response to DNA damage caused by cisplatin and radiation, thereby enhancing clinical outcomes, without increased toxicity. This trial explores the associated effect of WEE1 kinase inhibitor adavosertib (AZD1775).Methods and analysisThis phase I dose-finding, open-label, multicentre trial aims to determine the highest safe dose of AZD1775 in combination with cisplatin chemotherapy preoperatively (group A) as a window of opportunity trial, and in combination with postoperative cisplatin-based chemoradiation (group B).Modified time-to-event continual reassessment method will determine the recommended dose, recruiting up to 21 patients per group. Primary outcomes are recommended doses with predefined target dose-limiting toxicity probabilities of 25% monitored up to 42 days (group A), and 30% monitored up to 12 weeks (group B). Secondary outcomes are disease-free survival times (groups A and B). Exploratory objectives are evaluation of pharmacodynamic (PD) effects, identification and correlation of potential biomarkers with PD markers of DNA damage, determine rate of resection status and surgical complications for group A; and quality of life in group B.Ethics and disseminationResearch Ethics Committee, Edgbaston, West Midlands (REC reference 16/WM/0501) initial approval received on 18/01/2017. Results will be disseminated via peer-reviewed publication and presentation at international conferences.Trial registration numberISRCTN76291951 and NCT03028766.

Project description:ImportanceNational Comprehensive Cancer Network guidelines recommend weekly cisplatin as an alternative concurrent systemic therapy for definitive chemoradiation in patients with head and neck cancer. However, the impact of different levels of adherence to weekly cisplatin on outcomes stratified by human papillomavirus p16 status remains unclear.ObjectiveTo evaluate the association between the number of weekly cisplatin cycles and outcomes.Design, setting, and participantsThis retrospective, observational, single-institution cohort study at The Ohio State Comprehensive Cancer Center included patients with a diagnosis of nonmetastatic head and neck cancer between December 1, 2011, and March 30, 2020, who received chemoradiation. Data analysis was performed between March and May 2024.ExposureA total of 5, 6, or 7 to 8 weekly cisplatin cycles.Main outcomes and measuresThe primary outcomes were overall survival (OS), progression-free survival (PFS), locoregional failure (LRF), and distant failure (DF). Cox multivariable analysis was performed for variables associated with OS and PFS, and Fine-Gray multivariable analysis was performed for variables associated with LRF and DF.ResultsA total of 142 patients met the criteria (119 men [83.8%]; median [IQR] age, 59 [54-63] years). Median (IQR) follow-up was 46.8 (40.8-55.6) months. Among 92 patients with reasons for cisplatin interruption reported, the most common reason was low blood counts (42 patients [45.7%]). Those who missed weekly cisplatin cycles had worse OS (adjusted hazard ratio [aHR], 2.22; 95% CI, 1.19-4.17; P = .01) and PFS (aHR, 1.83; 95% CI, 1.06-3.15; P = .03) than those who received 7 to 8 cycles. Cancer control outcomes were comparable between these groups (LRF aHR, 0.53; 95% CI, 0.15-1.93; P = .34; DF aHR, 1.51; 95% CI, 0.60-3.82; P = .38). Patients with p16-negative tumors who missed weekly cisplatin cycles had worse OS (for every missing cisplatin cycle, aHR, 11.34, 1.51-84.94; P = .02) than those treated with 7 to 8 cycles. However, for those with p16-positive tumors, there were no statistically significant differences in OS between those who missed weekly cisplatin cycles vs others who received 7 to 8 cycles (aHR, 1.21; 95% CI, 0.47-3.14; P = .69).Conclusions and relevanceIn this cohort study of patients with head and neck cancer who received definitive chemoradiation, those with p16-negative tumors who missed weekly cisplatin cycles had lower OS than those who received 7 to 8 cycles, although OS was comparable between these groups for p16-positive tumors. Cytopenia represented the most common reason for cisplatin interruption.

Project description:BackgroundCisplatin resistance is one of the major contributors to the poor survival rate among head and neck cancer (HNC) patients. Focusing on the protein-protein interaction rather than a single protein could provide a better understanding of drug resistance. Thus, this study aimed to identify hub genes in a complex network of cisplatin resistance associated genes in HNC chemotherapy via a series of bioinformatic tools.MethodsThe genes involved in cisplatin resistance were retrieved from the NCBI gene database using "head and neck cancer" and "cisplatin resistance" as key words. The human genes retrieved were analyzed for their interactions and enriched using the STRING database. The interaction between KEGG pathways and genes was visualized in Cytoscape 3.7.2. Further, the hub gene was identified using the Cytohubba plugin of Cytoscape and validated using UALCAN and Human Protein Atlas database. Validated genes were investigated for the drug-gene interaction using the DGIbd database.ResultsOut of 137 genes obtained using key words, 133 were associated with cisplatin resistance in the human species. A total of 150 KEGG pathways, 82 cellular components, 123 molecular functions, and 1752 biological processes were modulated on enrichment analysis. Out of 37 hub genes, CCND1, AXL, CDKN2A, TERT, and EXH2 genes were found to have significant (p < 0.05) mRNA expression and effect on overall survival whereas protein expression was found to be positive for all the significant genes except TERT. Thus, they can be targeted with palbociclib, methotrexate, bortezomib and fluorouracil, sorafenib, dasatinib, carboplatin, paclitaxel, gemcitabine, imatinib, doxorubicin, and vorinostat.ConclusionAs the pathogenesis of head and neck cancer is complex, targeting hub genes and associated pathways involved in cisplatin resistance could bring a milestone change in the drug discovery and management of drug resistance which might uplift overall survival among HNC patients.
