News from Vienna More than 24 months have passed since CareDx, Inc., based in Brisbane, California, acquired Olerup’s parent company Allenex AB. Both companies have well established core products in transplantation and the combination of both sets of expertise creates a focused diagnostics company fully covering the pre- to post-transplantation continuum. Please read more about the offering from us to the transplant community in this issue of CareDx news.

Olerup QTYPE Really exciting news for us is the CE marking of the Olerup QTYPE, our rapid real time based HLA typing assay. The CE mark is a certification mark provided by our Notified Body indicates conformity to the In Vitro Diagnostics Directive and applicable standards. It is essential for a Europe-wide launch product and almost a prerequisite for Olerup QTYPE 11 availability in Europe.

Throughout the last year we have been successful with running many workshops around Europe of Olerup QTYPE on the Roche LightCycler® 480 II platform. This

was done through our own sales organization in Europe and in USA but also through our well-established distributor network in Europe. Inspired by the positive feedback we have received from these Olerup QTYPE 11 workshops we are not only continuing with them, but expanding the number we have planned. Recent work has been focusing on making Olerup QTYPE available also on the Applied Biosystems QuantStudio™ 6, QuantStudio 7 and ViiA™7. We also continue to add resolution to the product and improve our software solution (SCORE 6).

Cell-free DNA as a biomarker

Cell-free DNA (cf-DNA) is fragmented DNA in the bloodstream that originates from cells undergoing cell injury and death. When graft injury occurs, donor -derived cell-free DNA (dd-cfDNA) increases in the bloodstream. AlloSure measures dd-cfDNA and is a powerful, non-invasive tool for kidney transplant surveillance. At product launch, AlloSure will be covered by Medicare.

Olerup QTYPE: CE marked and an expanded instrument base

typing. Once the plate has been prepared, seal it with the included optically-clear sealing sheet, briefly centrifuge and place it in the real time cycler. Data is collected in real time.

The Olerup QTYPE system enables speed and precision in HLA typing. The assay has a total turnaround time from start to finish of 60 minutes and provides a low to intermediate resolution for samples requiring a fast turnaround time. With Olerup QTYPE, time is on your side!

We are proud to inform our European market that the Olerup QTYPE product has now been CE marked.

In addition, we are pleased to announce that the Olerup QTYPE instrument base has been expanded. When the product was launched at ASHI in 2016, it was available on the Roche LightCycler 480 II real time PCR instrument. Olerup QTYPE can now also be run on the Applied Biosystems QuantStudio 6, QuantStudio 7 and ViiA 7.

If you have one of these instruments and are interested in evaluating the performance of the Olerup QTYPE product, come visit us at the booth or talk to your local Olerup distributor!

Simple workflow The kit includes all necessary components for PCR, including a hot-start master mix.

Water, DNA and master mix need to be combined prior to dispensing this mixture across the plate. The dispensing can be performed manually or with automation. The assay is sensitive and requires only 5 μg of DNA, including overfill, for a full 11 locus

After the run finishes, the raw data can be imported into SCORE 6, our purpose-built software for real time data analysis. The well-known software has been simplified for increased user-friendliness and the underlying database technology upgraded for improved reliability. In the software, an Olerup QTYPE run is associated with sample-specific information to obtain the final typing result.

In addition, we realize that freezer space is valuable in the laboratories. To support our users, we recently reduced the box size of the Olerup QTYPE kit so that it takes up 50% less space.

In the year and a half since the Olerup QTYPE launch, we have performed over 60 product demonstrations in 13 different countries. A continuously increasing number of laboratories are now regular users with additional labs proceeding through their validation phase. Several thousand tests of the Olerup QTYPE test have now been performed. Not a bad start for our TaqMan-based approach for rapid and precise HLA typing!

Platform development In the last year, work has been focused on two fronts: CE marking of the product and enabling use of Olerup QTYPE on the Applied Biosystems instruments QS6, QS7 and ViiA 7.

In the early parts of this year, together with 3 centers, Olerup QTYPE was validated in a performance evaluation study, including 111 clinical samples. Based on this and a range of other studies demonstrating among other aspects, the stability, reproducibility, repeatability and accuracy of the product, the product was CE marked. If visiting EFI, please join our lunch symposium on Thursday at 12 o’clock for more information!

In collaboration with 17 clinical laboratories more than 300 clinical samples were analysed on 27 instruments including the Roche LightCycler 480 II, Applied Biosystems QS6, QS7 and ViiA 7. The SCORE 6 software has been upgraded to allow import of ABI data and to enable analysis.

In addition to this, we have added additional features in the product to improve and increase robustness and accuracy.

HLA typing within an hour ”An Olerup QTYPE 11 run on a validated real time PCR instrument takes approximately 45 minutes and, when adding time to prepare the plate and the results analysis, we have a full 11 loci typing in around an hour”, says Ben Passey, Development Manager at Olerup.

Precision in real time, multiplexing for best possible resolution The Olerup QTYPE HLA typing kits use TaqMan probe technology, a powerful and flexible multiplexing tool. This will allow us to have a kit with minimal ambiguities, enhanced resolution and gives us the flexibility to grow with the HLA database.

TaqMan probes also eliminate primer-dimers and PCR artefacts with no waiting for endpoint melt curves.

Briefly, TaqMan probes are sequence-specific with a fluorescent reporter molecule on one end and a fluorescence quencher molecule on the other end. Due to their close proximity on the probe, all the fluorescence emitted by the reporter is absorbed by the quencher molecule, resulting in no net signal. They are designed to bind between the two PCR primer and during the extension step, the PCR polymerase cleaves the TaqMan probe, freeing the fluorescent probe into the supernatant. With each cycle, the real time instrument automatically monitors the accumulation of fluorescence over time.

Continuous product improvements A full plate consists of 384 wells which can be detected in four different fluorescent channels giving us a total possibility of 1,532 potential reactions.

Similar to our trusted and proven approach to the Olerup SSP product line, we will continuously develop and improve the Olerup QTYPE product based on market needs. The plate is not even half full meaning that we will continue to improve resolution by adding reactions based on requirements.

Trusted and reliable support With more than 25 years experience in HLA, Olerup is your trusted partner in transplantation. We pioneered the way with our innovative Olerup SSP product line in the 90’s. We have continuously maintained a high-standard for this product line and are known for having the kits with the best resolution on the market. This is a promise we will continue to deliver on with our real-time product Olerup QTYPE, delivering speed and precision.

These parameters are then used to automatically detect a positive or negative amplification. Overall, each reaction is composed of at least two SSP primers and a sequence-specific TaqMan probe. Hence, each reaction uses three layers to determine specificity. Clearly, this increases the resolution power of each individual mix.

Olerup SBT update our other HLA typing product lines; Olerup SSP, and Olerup QTYPE. Furthermore, users may have noticed the significantly reduced sizes of our kit boxes, saving space both on our and the customer end. During the last year we have spent much effort in improving the Assign software, and in 2018 we are proud to have launched a new release of Assign v471, Olerup re-branded, but more importantly, updated the software to work also on a 64-bit operating environment. The 64-bit version of Olerup Assign SBT™ v471 provides faster data import and a faster HLA analysis experience.

CareDx HLA sequence-based typing products are developed and manufactured by CareDx Pty Ltd, our wholly owned subsidiary based in Fremantle, Australia. Our Fremantle team (see picture) can look back at a year of successful integration activities where the SBT business, acquired from Illumina in 2017, now is fully integrated in our organization. From a user view the most noticeable change has probably been the re-branding of the SBT product line, to Olerup SBT™, now similar to the branding of

cing products continue to be managed by the Olerup organization, ensuring on time delivery and expert help from our technical support when needed.

For the future we are committed to upgrade our sequencing product portfolio to meet new user needs and requirements. Work is on-going to provide assays enabling whole HLA gene sequencing, delivering HLA genotyping at the highest resolution.
