ASCO daily highlights: Saturday 1st June

Our team on the ground share 5 key highlights from day 2 at ASCO:

  1. Genetic testing can provide overwhelming information to recipients, especially patients, and not all of this information is clinically actionable yet. Clearer guidance is needed on reporting genetic test results, specifying which results should be included, so patients can make more informed decisions without confusion.

  2. Key features, such as linker cleavage enhancing ADC selectivity and new antibody conjugation sites improving stability, have contributed to decreased off-target toxicity and on-target off-tumor toxicity in new ADCs. However, biomarkers that can evaluate ADC toxicity and guide adjustments during early-phase trials to maximize therapeutic benefits and minimize toxicity are still missing.

  3. Dynamic biomarker testing should be implemented to monitor the efficacy of ADC treatment due to the development of acquired resistance. LBx-based real-time biomarker testing, spatial genomics, and molecular imaging can all contribute to the potential success in ADC treatment.

  4. Two large population-based studies (one global and one UK biobank study) further solidify the understanding that identifying pathogenic variants early can significantly inform cancer risk reduction and improve clinical outcomes. However, the actual genetic testing rate in practice falls significantly short of guideline recommendations. It is imperative to address this issue to ensure better healthcare outcomes for cancer patients.

  5. Genomic alterations in ctDNA enhance prognostic accuracy compared to clinical features alone. While evidence supports the prognostic value of ctDNA burden, its predictive value regarding the benefit of LuPSMA treatment requires further clinical validation.
