Summary

This summary is machine-generated.

Antibody-drug conjugates (ADCs) show superior response rates and progression-free survival in late-line cancer trials compared to comprehensive genomic profiling (CGP)-matched therapy. Early referral to Phase 1 trials is crucial for optimal outcomes.

Area Of Science

  • Oncology
  • Clinical Trials
  • Genomic Medicine

Background

  • Comprehensive genomic profiling (CGP)-matched therapy and antibody-drug conjugates (ADCs) are gaining traction.
  • Their efficacy in early-phase, late-line clinical trials requires further elucidation.

Purpose Of The Study

  • To evaluate clinical outcomes of CGP-matched therapy versus ADCs in advanced solid tumors treated in late-line clinical trials.
  • To identify prognostic factors influencing treatment response.

Main Methods

  • Retrospective chart review of 173 patients with advanced solid tumors in late-line trials (Jan 2020-Dec 2023).
  • Comparison of overall response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) between treatment groups.

Main Results

  • ADCs demonstrated the highest ORR (31.9%) and DCR (68.1%).
  • ADCs showed significantly longer median PFS (4.0 months) compared to CGP-matched (1.9 months) and other trials (1.7 months).
  • Multivariate analysis indicated ADCs improved PFS, while CGP-matched therapy improved OS.

Conclusions

  • ADCs enhance therapeutic responses in early-phase, late-line clinical trials for advanced solid tumors.
  • Prioritizing early referral to Phase 1 facilities and appropriate patient selection are vital for optimizing outcomes, rather than solely relying on CGP results.
