Single Mouse Study Format

The SMT format employs a single mouse per PDX model and treatment arm, thereby enabling a cost-effective investigation of in vivo efficacy in large panels of PDX models. The SMT format reliably identifies compounds that are strongly active (or inactive) across a panel of tumor models, and can be used to investigate the most promising candidate compounds, new indications or optimal drug combinations.

Possible applications include:

  • Identification of a large number of compounds in diverse tumor populations
  • Efficient and reliable identification of treatments with broad anti-tumor activity
  • Identification of resistance mechanisms
  • Strategic exploration of new drug combinations
  • Comprehensive exploration of one histotype
  • Screening of a particular molecular characteristic
  • Expansion of clinical indications by exploring other tumor types
  • Generation of data for biomarker analysis and identification
