Citoxlab President Keynote

Bulles News 6_9

Dear Valuable Customers,

The first half of 2015 confirmed and reinforced the trend seen in 2014 when we recorded increased numbers of projects entrusted to us by our clients. This positive trend comes from two key segments of our customers, large to midsize pharma as well as biotech companies. Indeed, the dramatic increase in biotech funding, initiated during Q4 2011-Q1 2012 and continuing to rise gradually over 2013, reached more than 54 billion USD in 2014, the highest recorded figure since 2000. This is of course a benefit shared by the entire CRO industry. A market survey by William Blair analysts updated in March of this year, just after the annual SOT meeting, confirmed this positive industry trend and the first two quarters of 2015 have seen new records in biotech funding.

For Citoxlab Group this translates into sales figures which increased at all 5 of our centres (Evreux and Saint-Nazaire, France; Montréal, Canada; Copenhagen, Denmark and Veszprem, Hungary). Globally, sales for Citoxlab Group increased by 22% over the first 6 months of 2015 compared to last year (54.2 vs. 44.5 Mi Euros). To face this increased demand from our customers, several of our sites hired new staff, and today our group employs more than 900 people.

Another trend to be noted is the increased complexity of the studies requested by our clients, which include evaluations like multiplex biomarkers analysis, diverse panels of cytometry, immunogenicity tests sometimes linked with cell-based assays, immunohistochemistry and multiplatform genomics investigations using Affymetrix gene chips or Illumina NGS. Our ability to offer a very large spectrum of biomarkers has become a driver for many of our customers.

I also would like to highlight our recent focus in safety pharmacology where, in addition to the classic studies to investigate cardiovascular function, we have been asked to perform more studies to assess effects on the central nervous system. We have collected validation data (in rats, dogs and NHPs) and we took the opportunity to share and publish these data in papers which were read by many colleagues (see below).

In early safety pharmacology, it is my pleasure to announce that we have decided to set up in vitro ion channel models in our Montreal facility, as we think that this service will become more necessary in the future after the recent CiPA analysis from the USFDA.

I hope that this Newsletter helps to keep you informed about the continued development of Citoxlab Group and about the services we provide with our best efforts to meet your needs, in particular in terms of scientific expertise, relevance and quality of the data and evaluation on the products you are committed to develop.

Citoxlab invests for new ophthalmology treatments

Bulle newsletter septMany Pharma and Biotech companies are currently interested in the treatment of diseases of the eye and defects of vision. Consequently, clients have come to Citoxlab with numerous ocular projects. One important target for new therapeutic approaches is macular degeneration, where small molecules, monoclonal antibodies and other therapeutic modalities are under evaluation. Gene therapy constructs are being developed to correct genetic deficiencies that are the basis of some inherited conditions affecting eyesight. As with other medicinal products, preclinical safety studies are required on these products involving an evaluation of tolerance and potential toxicity as well as studies to evaluate biodistribution using qPCR to trace the distribution and elimination of the product. Preclinical studies for ocular products are typically performed in rabbits, dogs, minipigs or monkeys and should follow the intended clinical route of administration. These studies often involve intravitreal injection, but may require more complex administration techniques such as retinal implantation or the use of sophisticated ocular devices. Follow-up of treated animals to demonstrate good tolerance of the drug can involve not only standard ophthalmological evaluations by trained veterinarians and histopathology performed by experienced pathologists, but also the evaluation of ocular function by electroretinography and detailed observations by optical coherence tomography (OCT). At Citoxlab, we offer each of these services and have started building reference data for OCT in dogs and monkeys. OCT is a non-invasive technique and offers several advantages for structural and functional evaluation of the retina. We hope that providing these tools for our clients will result in important clinical benefits for patients. We would be happy to discuss your projects in the area of ocular disease.

Citoxlab leads In Situ hybridization studies

Bulles News 6_5

Citoxlab offers a wide range of comprehensive immunohistochemistry (IHC) and in situ hybridization (ISH) services. These services allow you to rapidly visualize one or multiple proteins or to localize specific RNA sequences in human and animal tissues or cells using fluorescent or chromogenic methods. Multiple proteins may be localized at the same time in a tissue or cell using carefully selected fluorophores or chromogens. Multiplexing is a powerful tool when co-localization of proteins is needed.

The Citoxlab IHC & ISH platform is equipped with 4 Ventana automated staining machines, which makes workflow efficiency and flexibility easier. Aside from the panels of markers already available, such as those associated with inflammatory cell characterization and viral detection in monkeys, Citoxlab has the capabilities to develop many new markers, in oncology for example.

Citoxlab also has broad experience with Tissue Cross-Reactivity (TCR) and different types of antibodies including classical Ab, Fab fragment, biotinylated Ab, IgG4 Ab, Peg-Fab, bispecific Ab, human single chain variable fragment (scFv), cytotoxic – conjugated Ab (ADC) and vaccine induced Abs.

Citoxlab proposes a broad range of established protocols for over 100 different biomarkers in human and various lab animal tissues. Other staining protocols may be developed on request.

Dedicated board certified pathologists provide proficient scientific advice, best practices regarding documentation and cost effective solutions in the development of efficient methods to meet your expectations.

Bulles News 6_7

Science is the main focus of our daily research activities and the Citoxlab team is pleased to see that this passion for innovation in drug development is shared worldwide. Our team published three articles related to safety pharmacology last year and the scientific community responded very positively.

The central nervous system (CNS) was of major interest, with one article on sleep studies (including polysomnography with EEG, EOG and EMG)1 and another addressing seizure liability assessments across a range of species2. Both articles discuss important considerations during drug development and the interest of translational value from non-clinical research to patient populations.

The third article focuses on a non-invasive model for respiratory investigations in toxicology studies3.

As expected, regulatory aspects of drug safety testing remain a major theme in scientific discussions within our team, and the publications aimed to share ideas and concepts applied to drug discovery and development in the field of non-clinical regulatory studies. Our team remains committed to excellence in drug development, and we are pleased to share knowledge acquired in the exciting area of safety pharmacology.

Biomarkers included in Acute Radiation Syndrome studies

Bulles News 6_3

Biomarkers offer several advantages including longitudinal evaluations of biological progression in the same individuals and also a high translational value when the same biomarkers can be applied to the clinic. C-Reactive Protein (CRP) and Citrulline are well established diagnostic tools with solid scientific foundations to assess inflammation and gastrointestinal function, respectively. Our team has applied biomarker analysis technologies including ELISA and LC-MS/MS to characterize time course plasma concentrations in non-clinical studies. These biomarkers were qualified in normal individuals but also in efficacy models of acute radiation syndrome (ARS) for drug development. Normal values for these biomarkers were evaluated and compared across a range a species including rodents and non-rodents. Interestingly, circadian cycle effects were observed in the absence of drug treatment and also changes associated with feeding and other experimental conditions such as anaesthesia. Moreover, the kinetics of the changes were correlated with body surface area (BSA) providing a robust framework for results interpretation. This extensive characterization of clinically relevant biomarkers can be applied to non-clinical safety and efficacy studies to increase sensitivity in drug development. Our results will be presented at the 61st Annual Meeting of the Radiation Research Society (RRS) in Weston Florida, 2015 Sept 19-22.
