Rittenhouse: erlotinib-treted pt shown; day 4 T790M shown. day 25 tissue genotyping shown T790M, day 31 osimertinib responder #PMWC17

2:11pm January 25th 2017 via Hootsuite

Rittenhouse: Safety, cost, logistics, TAT: all problematic, so plasma testing attractive. #PMWC17

2:10pm January 25th 2017 via Hootsuite

Rittenhouse: Targeting EGFR in lung ca T790M point mutation; 3rd gen TKI (osimertinib) now req a re-biopsy. Plasma testing allowed. #PMWC17

.@helixcode Hi - in all the talks I attended, CNV from exomes not mentioned at all here at #PMWC17

.@Genomes2People @RobertCGreen Thank you for the kind word! Always, always enjoy Dr. Green's presentations; IIRC only heard him once before.

.@jgreid Alas I missed the BGI talk - due to travel delay. Would reach out to Rado, or BGI-Americas. On second Q not sure, sorry.

.@OmicsOmicsBlog Hi Keith - IIRC it was just the platform ("Roche Sequel") rather than a Roche assay.

9:13am January 25th 2017 via Hootsuite in reply to OmicsOmicsBlog

.@LincolnNadauld I do agree - the overall costs of WGS (incl analysis) is high, and a classic 'don't throw the baby w/the bathwater' #PMWC17

.@CrowdedHead You are most welcome! Quite a privilege to be here - thanks to @SeraCare

Beresford: Shortening time from Dx to Rx '16 ref https://t.co/Pge68IaxIf #PMWC17

3:15pm January 24th 2017 via Hootsuite

Beresford: "actionable results in 72h for pts with NSCLC" - shortening time from Dx to Rx for NSCLC. Usually 3-6w for tissue testing #PMWC17

3:13pm January 24th 2017 via Hootsuite

Beresford: genestrat test now has actionable muts (EGFR, ALK, ROS, RET), also T790M result; reflex to verstrat for Pt-Rx or TKI #PMWC17

3:12pm January 24th 2017 via Hootsuite

Beresford: Prognostic, based upon 8 parameters. Describes advanced-NSCLC for their VeriStat, covered by Medicare, 220M pt coverage #PMWC17

3:11pm January 24th 2017 via Hootsuite

Beresford: Estimated 150K publications for biomarkers. They have a MALDI-ToF MS test called VeriStrat, with spectra #PMWC17

Otto: Critical to look beyond ctDNA - CTCs, tissues, proteins, RNA. #PMWC17

3:03pm January 24th 2017 via Hootsuite

Otto: Need to demonstrate contam. control, detection. Precision for intra- and inter-run. Also concordance w/orthogonal validation #PMWC17

3:02pm January 24th 2017 via Hootsuite

Otto: Claim 50% conversion efficiency for >5000x sequencing. Analytic validation - use mix of cell lines, synthetic spike-ins #PMWC17

3:01pm January 24th 2017 via Hootsuite

Otto: They've built kits to maximize stability. Also: how to interpret negative results? 2w stability in their kits. #PMWC17

3:00pm January 24th 2017 via Hootsuite

Otto: Clinical challenge: no path review, thus need for low AF measurement. Need SNV, indel, CNA, fusions. Limited smpl stablity #PMWC17

2:57pm January 24th 2017 via Hootsuite

Otto: Yield, dynamic range is highly variable. ctDNA is indirect interrogation. Potential insight into 'systemic' disease (resist) #PMWC17

Pla: And spec shown per-sample, not per-base. They require 2x 10mL blood, spec. >99% on a per-sample basis #PMWC17

2:42pm January 24th 2017 via Hootsuite

Pla: Lack of standardization how data is reported, can mislead. No single measure - report sens for SNVs, indels, Fusions, CNV gain #PMWC17

2:41pm January 24th 2017 via Hootsuite

Pla: Analytical performance - base specificity, incorrect calls/sample based on 100kb panels has 100 incorrect calls at 99.9% #PMWC17

Butte: Next big data to share? Wuest: Individual connected devices. Filling in lots of gaps that are needed (i.e. mood, depression) #PMWC17

2:29pm January 24th 2017 via Hootsuite

Wuest: Perhaps sharing of clinical data anonymously. #PMWC17

2:24pm January 24th 2017 via Hootsuite

Q: Value of neg. results? Butte: Still an environment of distrust; sharing starts with journal editors, to funding agencies, to law #PMWC17
