Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Objective Response Rate (ORR) Definition: Proportion of patients achieving either complete response (CR) or partial response (PR) as assessed by RECIST v1.1 criteria on serial imaging. Timepoint: First response assessment at ~8 weeks after treatment initiation, then every 8 12 weeks. | — |
Secondary
| Measure | Time frame |
|---|---|
| Progression-Free Survival (PFS) Timepoint: Time from initiation of systemic therapy to documented radiologic or clinical disease progression or death from any cause. Based on RECIST v1.1 & clinical judgment;Concordance Rate Between Tissue and Liquid Biopsy NGS The proportion of overlapping mutations (e.g., KRAS, TP53, BRAF) identified in both tissue and ctDNA samples at baseline, using Cohen s kappa to assess agreement. Timepoint: At baseline Before treatment;Overall Survival (OS) Timepoint: Time from initiation of systemic therapy to death from any cause. ;ctDNA ResponseTimepoint: Every 2 3 treatment cycles (~6 8 weeks).;Molecular Progression via ctDNATimepoint: During follow-up blood draws every 2 cycles;Resistance Mutation Detection Definition: Identification of known resistance mutationsTimepoint: till progression | — |
