Mansfield: Concludes with intention of guidance - encouraging innovation, assure quality and reliability of NGS-based tests #NGDx16

11:53am August 24th 2016 via Hootsuite

Mansfield: Use of genetic databases - must be public, aggregated data, voluntary db recognition path (similar to stds) #NGDx16

11:51am August 24th 2016 via Hootsuite

Mansfield: May move to avoid pre-market review in the future. #NGDx16

11:50am August 24th 2016 via Hootsuite

Mansfield: Class-III (high risk) 'by default if we haven't seen it before'. Classified downward via de novo. #NGDx16

11:49am August 24th 2016 via Hootsuite

Mansfield: Need for comparator method (orthogonal validation); need for documentation of validation (really impt to FDA) w/CI's #NGDx16

11:47am August 24th 2016 via Hootsuite

Mansfield: 'We say it is up to you to indicate how many specimens needed for validation' but have to justify rationale #NGDx16

11:46am August 24th 2016 via Hootsuite

Mansfield: Need appropriate specimen type; can be very difficult; need to understand commutability of synthetic materials #NGDx16

11:45am August 24th 2016 via Hootsuite

Mansfield: Need to see evaluation as part of end-to-end; var types, seq context, FASTQ file testing indel accuracy #NGDx16

11:45am August 24th 2016 via Hootsuite

Mansfield: Need to know the result; coverage the metric that 'always should be used', looking for comment; end-to-end test system #NGDx16

11:44am August 24th 2016 via Hootsuite

Mansfield: Worry about pseudogenes, cross-contamination issues. Min perf thresholds - accuracy 99.9% and precision 95% (95% CI) #NGDx16

11:43am August 24th 2016 via Hootsuite

Mansfield: Different informatics pipelines, interpretation software and human interpretation. Thus: what performance metrics? #NGDx16

11:40am August 24th 2016 via Hootsuite

Mansfield: Design stds need iteration; informed by intended use and indication. Could be from clinician or lab; det perf needs #NGDx16

11:39am August 24th 2016 via Hootsuite

Mansfield: 'Stds orgs can do this much more quickly'; they are req'd to have consensus of all stakeholders. Not just one sector #NGDx16

11:37am August 24th 2016 via Hootsuite

Mansfield: Technical rec's: describes approach to test design, accommodates different designs, components, indications. #NGDx16

11:37am August 24th 2016 via Hootsuite

Mansfield: Draft guidances for public comment; targeted or WES. Others in future: inf disease, NIPT, liquid biopsy, solid tumor #NGDx16

11:36am August 24th 2016 via Hootsuite

Mansfield: Started with inh genetic diseases b/c it was felt it was understood better, as a place to start. #NGDx16

11:32am August 24th 2016 via Hootsuite

Mansfield: Purpose of draft guidelines - anticipate needs, dev. an efficient path-to-market. Standards, databases, open processes #NGDx16

RT @h2so4hurts: JO: CTC's also contain cells that won't survive metastasis so how relevant this reservoir is is a huge question #NGDx16

11:22am August 24th 2016 via Hootsuite

RT @h2so4hurts: JO: CTC's don't just pop into the bloodstream, basically what's in the blood may not be what's in the tumor #NGDx16

Tezak: Focus was on germline. #NGDx16

9:10am August 24th 2016 via Hootsuite

Tezak: Key themes: design process; perf standards; Interest in precisionFDA; need for transp for data; datasharing impt #NGDx16
