1 Setting new standards in IVF

2 The clinical challenge Embryo aneuploidy is known to increase with maternal age, causing increase in miscarriage rates and decrease in live birth rates. Due to this age related reduction in live birth rate many couples turn to IVF. Despite major technical advances in IVF procedures over the last 30 years IVF success rates remain low. According to recent data, women under 35 years can on average expect a live birth in 32-33% of cycles started a rate which reduces to under 15% for women over Oocyte aneuploidy and maternal age chromosome aneuploidy screening Recent RCT evidence 2 shows that 45% of embryos are aneuploid, even in good prognosis patients. Selectively implanting euploid embryos is therefore critical to reducing miscarriage rates, improving success rates and increasing single embryo transfer (SET). 24sure sets the standard for screening aneuploidy with biopsies from all stages of embryo development Maternal age Aneuploidy (%) Live birth (%) Miscarriage (%) 1 HFEA.

3 Significant increase in pregnancy rates The first published randomised prospective IVF study of pre-implantation chromosome analysis using 24sure demonstrates that selectively implanting euploid embryos significantly increases pregnancy rates. Yang et al (2012) report a 65% increase in pregnancy at 20 weeks on a good prognosis patient group. A 69.1% pregnancy rate was achieved after 24sure selection of euploid embryos (n=55) versus 41.7% after standard morphological selection of embryos (n=48). Selection was carried out on fresh day 5 embryos and single embryos were transferred. Results of this study provide direct evidence that 24sure analysis can deliver increases in pregnancy rates even in younger, good prognosis patients who are thought more likely to have favourable IVF outcomes. 24sure comprehensive chromosomal screening has been clinically proven to be the effective means to select the chromosomally normal embryo(s) for transfer to ensure a healthy pregnancy for infertile patients.

4 Rapid results from single cells 24sure is widely used with cells from all stages of embryo development. Polar bodies 24sure the new standard for preimplantation embryo screening Accurate and reliable technologies are essential for preimplantation genetic screening. 24sure screens all 24 chromosomes and can be used to screen for aneuploidy in first and second polar bodies, blastomere biopsies and trophectoderm biopsies within a fresh IVF cycle. 24sure is automated and objective which ensures that a high degree of confidence can be placed in the results so that only euploid embryos are implanted. Screening with 24sure can be completed in 12 hours and therefore does not interfere with tight schedules of a fresh IVF cycle. Blastomeres Labelling Sample preparation and amplification 3 hours Trophectoderm hours Reliable results in under 12 hours 24sure uses simple protocols familiar to laboratories experienced in classical molecular techniques. Protocols have been optimised for routine application with minimal tube transfers, documented quality control stages and flexible stop points. 24sure requires minimal specialist hardware and is compatible with low cost, 10 µm, laser scanners. Where high throughput operation is required optional hardware and protocol stages may be substituted to enable plate level operation.

5 Over 200,000 clinical biopsies processed to date. Independent scientific evidence Multiple papers report positive results, the first RCT has been published and many are ongoing. Over 20 peer-reviewed publications and more than 70 conference abstracts have been published, including the first preimplantation validation study undertaken by ESHRE. See the 24sure publication booklet for more details. We ve provided this service to our patients for just over a year and already about 20 babies have been born and another 50 are on the way. It s a significant breakthrough for patients who are struggling to become pregnant.

6 A complete data analysis and information management system All BlueGnome microarrays are supplied with complementary licenses to our BlueFuse software which provides a complete solution for the analysis, storage and reporting of 24sure results. BlueFuse supports the complete laboratory workflow, from sample receipt to report sign off, and is trusted by over 200 of the world s leading microarray laboratories to deliver high throughput and scalable microarray services. Sample database BlueFuse is built upon a scalable SQL database in which all sample details, experimental information and results are securely stored. Simple filters, powerful queries and a visual representation of each IVF cycle ensure the right information is available whenever it is required. Automated analysis Microarray images, loaded directly from the scanner, are processed fully automatically, saving time and guaranteeing complete reproducibility. Single click short cuts ensure rapid access to microarray images for quality control purposes.

7 Clear profiles Powerful visualisation facilities generate profiles from thousands of independent measurements from each 24sure microarray to enable the status of each chromosome to be fully understood and the basis of results confirmed. Profiles are generated against both male and female references in order to enable reliable interpretation sex chromosomes. Concise reports Sophisticated algorithms calculate and call the status of each chromosome as either normal or abnormal, backed by a confidence estimate reflecting the degree of assay noise or ambiguity in the underlying biology. In addition to delivering complete reproducibility and objectivity this approach ensures results are fully comparable between the newest 24sure laboratory and the largest studies published in the literature. At the end of the process an automated cycle report is generated.

8 The complete package Setting up a new microarray protocol and sourcing all equipment can be time and resource intensive. By providing all consumables and the key capital equipment needed to deliver 24sure screening BlueGnome enables you to confidently report accurate results with minimum start up time. BlueGnome provides a complete suite of products to support the 24sure protocol including; SurePlex DNA Amplification System, labelling systems and reference DNA and two microarray formats optimised for different investigations. 24sure 24sure V3 is designed for the investigation of whole chromosome aneuploidy and uses analytical methods to produce a simple report of aneuploidy in all 24 chromosomes, including the sex chromosomes. 24sure+ is designed for the investigation of sub chromosome imbalances in embryos of reciprocal translocation carriers. 24sure+ includes increased coverage of pericentrometic and subtelomeric regions to ensure the identification and reporting of the smallest derived chromosome fragments. 24sure opens up the exciting possibility to perform PGS not just in complicated patients such as those with poor ovarian reserve, but also egg donors and young women as abnormal embryos are common at any age.

10 Biographies Professor Alan Handyside Professor Handyside joined BlueGnome in 2010 as Head of PGD. He was the first chairman of the European Society for Human Reproduction and Embryology (ESHRE) Special Interest Group in Reproductive Genetics and co-founder and first chairman of the ESHRE PGD Consortium. Gary Harton Gary joined BlueGnome earlier this year as the Americas IVF Business Development Manager. He has more than 20 years experience in PGD laboratories and numerous published articles, abstracts and book chapters. Selected publications Yang et al (2012) report a 65% increase in pregnancy at 20 weeks, with a 69.1% pregnancy rate after 24sure selection of euploid embryos (n=55) versus 41.7% after standard morphological selection of embryos (n=48). Results of this study provide direct evidence that 24sure analysis can deliver increase in pregnancy rates even in younger patients who are thought more likely to have favourable IVF outcomes. Results of the ESHRE PGS proof of principle study concluded that the ploidy of embryos could be predicted with acceptable accuracy using 24sure analysis of both polar bodies. 195 zygotes were successfully analysed - 28% normal, 72% aneuploid.

11 Dr. Tony Gordon Tony joined BlueGnome in 2006 as the first CytoChip arrays were launched and initiated the 24sure business area in He has 17 years experience in molecular cytogenetic diagnostics. 24sure, successfully used in the initial ESHRE PGS taskforce study to assess the use of microarrays in PGS (June 2010), has now been selected for ESHRE s six centre full RCT trial (May 2011). Hodes-Wertz et al., (2012) analysed 2,282 embryos from couples with idiopathic recurrent pregnancy loss (RPL) using 24sure of which 35% were euploid and 60% aneuploid. In 181 transfer cycles the miscarriage rate was only 6.9% compared to the expected rate of 33.5% in an RPL control population and 23.7% in an infertile control group therefore showing a significant decrease in the miscarriage rate of RPL patients. Fiorentino et al. (2011) analysed 200 samples, 93.5% were successfully amplified, diagnosed and confirmed using STR analysis. Only 16% of samples were chromosomally normal which translated to embryos being suitable for transfer in 17/28 cycles. A pregnancy rate of 70.6% per embryo transfer was achieved in this cohort.
