Intended Use

The Illumina MiSeqDx(TM) Cystic Fibrosis Clinical Sequencing Assay is a targeted sequencing in vitro diagnostic system that re-sequences the protein coding regions and intrones of the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene in genomic DNA isolated from human periphers collected in K2EDTA. The test detects single nucleotide variants, and small InDels within the region sequenced, and additionally reports on two deep intronic mutations and two large deletions. The test is intended to be used on the Illumina MiSeqDx Instrument.

The test is intended to be used as an aid in the diagnosis of individuals with suspected cystic fibrosis (CF). The test is most appropriate when the patient has an atypical or non-classic presentation of CF or when other mutation panels have failed to identify both causative mutations. The results of the test are intented by a board-certified clinical molecular geneticist or equivalent and should be used in conjunction with other available information including clinical symptoms, other diagnostic tess, and family history. This test is not indicated for use for stand-alone diagnostic testing, for pre-implantation testing, carrier screening, newborn screening, or population screening.

Device Description

The Illumina MiSeqDx Cystic Fibrosis Clinical Sequencing Assay consists of library preparation and sample indexing reagents, sequencing reagents and consumables, MiSeqDx instrument and data analysis software. Testing begins with genomic DNA from a peripheral whole blood sample. The genomic DNA is processed through the library preparation steps, which specifically amplifies the intended genomic regions of each sample while also adding the indexes for sample identification. Flow cell capture sequences are also added to the amplified products. The resulting sample libraries are then transferred into a MiSeqDx reagent cartridge which contains all of the reagents required for cluster generation and sequencing (Sequencing By Synthesis). The MiSeqDx Cartridge, MiSeqDx Flow Cell, and MiSeqDx SBS Solution (PR2) are then inserted into the MiSeqDx instrument, which performs cluster generation, sequencing and data analysis.

Study Details

2. Sample Size Used for the Test Set and Data Provenance

  • Accuracy Study Test Set:

    • Total Samples: 500
    • Clinical Samples: 355 (archived, anonymized gDNA from human blood) - Country of origin not specified, but the review is by the US FDA.
    • Commercial Cell Line Samples: 11 (from clinical accuracy study) + 68 (from reproducibility study) = 79
    • Clinical Samples (from extraction method evaluation): 14
    • Synthetic Plasmid Samples: 52
    • Data Provenance: Retrospective for archived clinical samples, prospective for cell line and synthetic samples generated for the study.
  • Reproducibility Study Test Set:

    • Total Samples: 46 distinct samples (implied from the HGVS tables, with many tested in multiple replicates). The tables show analysis for 68 samples, each tested across 3 sites, with 2 operators each doing 3 runs per site, and with some samples having multiple replicates within those runs. This results in a large number of individual tests. The text explicitly states 68 cell line samples were evaluated in the reproducibility study for accuracy data.
    • Data Provenance: Prospective (generated specifically for the study). The operator details suggest this was done as part of the validation study.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

  • The ground truth reference methods were Sanger bi-directional sequencing and validated PCR based assays.
  • The text does not specify the number of experts used to establish the ground truth for Sanger sequencing or the PCR assays, nor their specific qualifications. It only states these were "reference methods."

4. Adjudication Method for the Test Set

  • The text mentions that "All results are based on initial testing. No repeat testing was done for this study" for the accuracy study. For reproducibility, some samples had "no calls" or "miscalls" initially, and further investigation was done (e.g., misidentified variant, low level contamination, improperly prepared synthetic specimen, switched samples). However, a formal adjudication method (e.g., 2+1, 3+1) involving a specific number of experts to resolve discrepancies against the reference is not explicitly described. The determination of miscalls and no calls seems to stem from comparison with the reference methods.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

  • No, an MRMC comparative effectiveness study involving human readers with and without AI assistance was not done. This study focuses on the standalone analytical performance (accuracy, reproducibility) of the device (an in vitro diagnostic system for genetic sequencing), not on its impact on human reader performance.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

  • Yes, a standalone performance study was done. The entire accuracy and reproducibility analysis describes the performance of the Illumina MiSeqDx Cystic Fibrosis Clinical Sequencing Assay (which includes the instrument and data analysis software) in detecting genetic variants. The results (PA, NA, OA, call rates) are indicative of the algorithm's performance compared to established reference methods (Sanger sequencing and PCR assays). The "human-in-the-loop" aspect for interpretation is mentioned in the intended use, where results are to be interpreted by a board-certified clinical molecular geneticist, but the performance metrics provided are for the device's ability to 'call' the variants.

7. The Type of Ground Truth Used

  • Expert Consensus (implied via Gold Standard Methods): The primary ground truth for SNVs and small InDels was Sanger bi-directional sequencing. For large deletions, two validated PCR-based assays were used, with accuracy confirmed by Sanger Sequencing. These are considered gold-standard methods in molecular diagnostics, implying an expert-established and validated ground truth.

8. The Sample Size for the Training Set

  • The document does not specify a training set size. As this is a performance validation document for a sequencing assay, it describes the testing of the device rather than the development or training of an AI model in the conventional sense. The "MiSeqDx instrument and data analysis software" are components, but details on their development/training are not provided in this regulatory summary.

9. How the Ground Truth for the Training Set Was Established

  • Since a training set is not explicitly mentioned or detailed for the device's software/algorithm development, the method for establishing its ground truth is not provided in this document. The focus is on validating the final product's performance against reference standards.

PERFORMANCE.CHARACTERISTICS

Accuracy

Accuracy of the Illumina MiSeqDx Cystic Fibrosis Clinical Sequencing Assay was assessed by evaluating 500 samples representing a wide variety of CFTR variants from four separate sources. The primary source of accuracy data was a clinical accuracy study conducted using a panel of 366 samples. The majority (n = 355) of

{6}------------------------------------------------

samples consisted of archived, anonymized clinical gDNA specimens isolated from human blood, the remaining 11 samples were obtained from commercially available cell line specimens.

Data from this study was supplemented with accuracy data from 68 cell line samples evaluated in the reproducibility study, 14 clinical samples from the extraction method evaluation analytical study, and 52 synthetic plasmid samples. The synthetic plasmids were designed to include the genomic context of rare variants, and contained anywhere from 1 to 10 variants within the same construct. They were linearized, diluted to genomic DNA equivalent copy numbers, and blended with human genomic DNA samples of wild type genotype at equivalent copy numbers to mimic a heterozygous sample.

For the MiSeqDx Cystic Fibrosis Clinical Sequencing Assay, a total of 5,206 positions were compared to the reference methods of Sanger bi-directional sequencing and PCR testing. The genotyping results for SNV and small InDel sites, including the PolyTG/PolyT region, were compared to Sanger bi-directional sequence analysis.

Two validated PCR based assays were used as the reference method for the two large deletions in the panel. Each duplex PCR assay made use of 2 primer sets to discriminate between wild type, heterozygous; and homozygous genotypes. One of the primer sets was designed to flank the deletion breakpoints, whereas the other amplified a region internal to the deletion. The two products were detected by size separation on an agarose gel. The PCR assays were validated using a panel of 28 samples in all (22 samples for each deletion) consisting of cell line and blood derived genomic DNA samples, and synthetic plasmids which encompassed the WT, HET and HOM genotypes for each large deletion. The PCR assays were confirmed to have 100% specificity and reproducibility for all samples tested, by evaluation of PCR products on an agarose gel. The accuracy of the PCR assays was confirmed using Sanger Sequencing and found to be 100% for all samples.

Accuracy was determined for each genotype through three statistical measures. Positive Agreement (PA) was calculated for each variant genotype by dividing the number of samples with agreeing variant calls by the total number of samples with that variant as identified by the reference methods. Negative Agreement (NA) was calculated across all wild type (WT) positions by dividing the number of concordant WT positions by the total number of WT positions as

defined by the reference methods. Overall Agreement (OA) was calculated across all reported positions by dividing the number of concordant WT and variant positions by the total number of reported positions as determined by the reference methods.

The MiSeqDx Cystic Fibrosis Clinical Sequencing Assay had a genotype-level PA of 99.66% including the PolyTG/PolyT variants and 100%, excluding PolyTG/PolyT variants (Table 1). The NA for all wild types was >99.99% and the OA for all WT and variants was >99.99%. The PolyTG/PolyT variant PA was 98.44%. All results are based on initial testing. No repeat testing was done for this study.

Accuracy of the PolyTG/PolyT variants is demonstrated in Table 2.

nowever indicated that the variant was in fact homozygous and incorrectly reported. MiSeqDx reported the variant as The Sanger report listed the P205S variant as heterozygous for the clinical sample. A review of the Sanger trac omozygous.

One of the discordant results was from the reproducibility study. The PolyTG/PolyT result for the sampl ncordant across all 18 replicates, but discordant with Sanger bi-directional sequencing.

The original synthetic heterozygous specimen was determined to be improperly prepared. When it was subsequen ested after it was re-prepared, using the same plasmid, it would be detected

ole, Sanger synthetic sample heterozygous for exon 8 was reported as heterozygous for the variant CFTR dele22, 23. Fur nvestigation revealed that this result was likely from low level contamination. Additionally, for a second samply ners could not fully detect the variant Q1463Q due to indels both upstream and downstream of the variant PA excluding PolyTG/PolyT calls was 100%

DNA Extraction

Three commonly used, commercially available extraction methods representing magnetic bead extraction, alcohol precipitation and silica filter column isolation methods, were evaluated using K2EDTA anti-coagulated whole blood. A total of 14 blood samples were used during the study; two were wild type, while the remaining samples carried unique genotypes representing 9 different variants, including both common and rare variants. For the polyTG/polyT variation, samples with (T)5-9 and (TG)10-12 were included. The three DNA extraction methods were tested independently by 2 different operators who each performed 3 runs per extraction method. Each extraction was performed by each operator on different days. The DNA concentration and A260/A280 ratio of the extracted gDNA samples was determined using spectrophotometry. The total sample size for each extraction method in this study was 168 (14 samples x 2 operators/extraction method x 3 runs/operator x 2 replicates/extracted gDNA sample).

DNA input

The DNA input range of the Illumina MiSeqDx Cystic Fibrosis Clinical Sequencing Assay was evaluated by performing a serial dilution study using 14 representative DNA samples containing 16 unique CF variants. Each sample was tested in duplicate at 9 DNA input levels ranging from 1250 ng to 1 ng (1250 ng, 500 ng, 250 ng, 100 ng, 50 ng, 25 ng, 10 ng, 5 ng, and 1 ng). For determination of accuracy, sample genotypes were compared to bidirectional Sanger sequencing

{64}------------------------------------------------

data and the deletions were compared to PCR assay. 1250 ng and 25 ng were identified as the upper and lower bound for DNA input respectively as they had ≥95% sample first pass rate with no incorrect calls (100% accuracy and call rate).

DNA inputs of 1250 ng, 250 ng, and 100 ng were further tested with 4 representative DNA samples and at least 20 replicates per DNA input level for each sample (n= 4 x 20=80 samples), while the lower bound of 25 ng was tested with 14 samples, 20 replicates for each sample (n=14 x 20=280 samples). The accuracy and sample first pass rate was 100% at all DNA input levels.

Interfering Substances

To assess the impact of interfering substances on the Illumina MiSeqDx Cystic Fibrosis System, the performance of the assay was evaluated in the presence and absence of potential interferents. Sixteen whole blood specimens having unique genotypes were included in the study. Four endogenous interfering substances (bilirubin, cholesterol, hemoglobin, and triglycerides) were tested by spiking them into blood specimens prior to DNA extraction. The concentration limits for each substance is shown in the table below. Additionally, to assess interference resulting from blood collection (short draw), EDTA was spiked into blood samples, and to assess interference resulting from sample preparation, the final wash buffer from a silica filter column isolation method was added to purified genomic DNA.

The MiSeqDx Cystic Fibrosis Clinical Sequencing Assay achieved 100% call rate for all samples tested, and 100% reproducibility in genotype calls between samples in the presence and absence of interfering substances. No interference was observed for any of the potential interferents.

To assess the impact of multiplexing index primer interference, a cross contamination study using two samples, each with unique homozygous genotypes at 4 different genomic positions, and two respective index primers was performed. NO change in variant calling was observed with contamination levels <40%. The sample genotype became heterozygous when contamination levels were ≥40%. ***
