D-TECT: Pretreatment D-dimers and Disease Control in Advanced cSCC Treated With Cemiplimab (D-TECT)
D-TECT: Prospective Multicenter Evaluation of Pretreatment D-dimer Levels as a Predictor of Disease Control in Advanced Cutaneous Squamous Cell Carcinoma Treated With Cemiplimab
D-TECT is a prospective, multicenter, non-interventional observational study investigating whether pretreatment D-dimer levels predict disease control in patients with locally advanced or metastatic cutaneous squamous cell carcinoma treated with cemiplimab in routine clinical care.
D-dimers are routinely available laboratory markers related to activation of the coagulation system. Previous single-center data suggest that elevated pretreatment D-dimer levels may be associated with poorer disease control under cemiplimab. In D-TECT, a single pretreatment D-dimer value and prospectively collected routine clinical follow-up data will be analyzed to validate this association in a multicenter real-world setting. No study-specific treatment decisions, imaging procedures, or additional blood draws are mandated by the study.

Yksityiskohtainen kuvaus
Cutaneous squamous cell carcinoma (cSCC) is one of the most common skin cancers. While most cases can be treated with curative local therapy, a subgroup of patients develops locally advanced or metastatic disease requiring systemic treatment. Cemiplimab, a PD-1 inhibitor, is an established systemic treatment option for advanced cSCC. However, validated routine biomarkers predicting disease control under cemiplimab are lacking.
D-dimers are fibrin degradation products and sensitive markers of coagulation activation. In a prior single-center retrospective analysis, elevated pretreatment D-dimer levels were associated with lower disease control, lower objective response, and shorter progression-free survival in patients with advanced cSCC treated with cemiplimab. D-TECT is designed to prospectively validate this observation in a multicenter real-world cohort.
Eligible patients are adults with histologically confirmed locally advanced or metastatic cSCC for whom cemiplimab treatment is planned as part of routine clinical care. A D-dimer measurement is documented within 7 days before the first cemiplimab dose up to the day of first administration before infusion. Subsequent clinical data, including tumor response, progression, survival, treatment discontinuation, and thromboembolic events, are collected from routine medical records during follow-up.
The primary endpoint is disease control within the first 6 months after initiation of cemiplimab. The primary confirmatory analysis compares disease control between patients with high versus low pretreatment D-dimer values using the prespecified cutoff of 0.91 mg/L FEU derived from the prior single-center study. If the primary analysis is statistically significant, the same primary endpoint will be tested hierarchically using the local laboratory-defined upper limit of normal. Additional analyses include objective response rate, progression-free survival, overall survival, thromboembolic events, diagnostic performance measures of the predefined cutoffs, sensitivity analyses, and exploratory analyses addressing inter-site assay heterogeneity.

Disease Control Rate Within the First 6 Months of Cemiplimab Treatment
Aikaikkuna: From start of cemiplimab treatment through 6 months
|
Disease control rate is defined as the proportion of participants with complete response, partial response, or stable disease according to clinical and/or radiological assessment in routine care within the first 6 months after initiation of cemiplimab.
Participants with documented progression, death, or treatment discontinuation due to clinical progression within the first 6 months are considered not to have disease control.
Participants without documented progression or death but without evaluable clinical or radiological follow-up assessment within the first 6 months are considered not evaluable for the primary analysis.
The primary confirmatory analysis compares disease control between participants with high versus low pretreatment D-dimer levels using the prespecified cutoff of 0.91 mg/L FEU.
If statistically significant, the same primary endpoint will be tested hierarchically using the local laboratory-defined upper limit of normal.
