The consensus diagnostic criteria for HER2+ mCRC
• IHC 3+
or
• IHC 2+ and FISH HER2/CEP17 ratio ≥ 2.0
Tumor content >10% for surgically resected specimens(separate quantity criteria were established for biopsy specimens)
We were able to verify the HER2 classification consistency between CNV by NGS and IHC/FISH by harmonizing diagnostic criteria for HER2+. This strategy can help establish diagnostic criteria for HER2+ cancer by allowing for different methodologies to be used for pts screening for trial eligibility.

The CNV in cross-validation of two NGS panels showed strong correlation (r: 0.98, P < 0.0001). The CNV in patients fulfilling the consensus criteria was more than 4.0 in all cases, providing the accuracy of the IHC/FISH criteria and cross-validation of NGS panels.

Scientific Plausibility; Are biology between MSI-H CRC and Non-CRC the same or different?
◆ MSI-H cancer, regardless of tumor histology, is associated with a high mutational burden (hypermutatedphenotype)
◆ High mutational burden leads to high neoantigen expression
◆ High neoantigen expression leads to autologous immune recognition of cancer cells
◆ By blocking PD-1 on tumor neoantigen-specific T cells, pembrolizumab can activate anti-tumor immune responses
◆ Hypothesis: PD-1 blockade can restore effective anti-tumor immunity in MSI-H cancer, regardless of cancer type

MSI/MMR Part MSI / MMR should be tested prior to or during the standard treatment for advanced solid
tumour. [LoE: V, GoR: A] Validated NGS is recommended for testing either upfront or when IHC is equivocal or not
available. [LoE: III, GoR for testing: B]
NTRK Part NTRK fusion testing should be considered prior to or during the standard treatment for
advanced solid tumour. [LoE: V, GoR: B] NGS which detects NTRK fusion is recommended for testing NTRK fusion. [LoE: V, GoR: C]

Tumor-agnostic
Challenges in drug development for a tumor-agnostic indication
• Study design for providing evidence of clinical efficacy (vs traditional randomized controlled studies)
• Identification of study population
What we learned from the Tumor-agnostic Approval Goal is to identify patients most likely to benefit from treatment
The increasing number of novel targets for ADC will likely cross many tumor histologies. ADCs targeting HER2 are in clinical trials against a variety of receptor expressing cancers, and the opportunity for tumor agnostic development seems very plausible. The era of focusing on the tumor’s molecular biology has arrived and will forever alter our approach to drug development.
