Nov 21, 2019, 04:32 ET
GENEVA, Nov. 21, 2019 /PRNewswire/ — AnaPath Services GmbH, the Swiss CRO specialized in histopathology, has acquired legacy Envigo CRS S.A.U. a CRO for non-clinical safety assessment on November 5th , 2019.
With this step Envigo CRS was renamed to AnaPath Research S.A.U.
Furthermore Jorge Zapatero Lorenzo was appointed the general manager of AnaPath Research. Mr Zapatero has been with the company from 1986 until 2014 in roles of increasing responsibility including general manager. This merger represents a back integration as both companies worked previously together within RCC / Harlan Laboratories Spain and Switzerland. After separating due to a buyer of Harlan in 2013, AnaPath developed into a globally recognized expert CRO in histopathology and toxicology.
Common history, personal relationship and shared values will make a quick start and integration as one CRO possible; after implementation of technical upgrades, GLP in vivo studies start January 2020. This merger enhances AnaPath’s capabilities and warranties a quick and clean performance of complete safety assessment packages under one roof. The basis for this statement is given by thorough knowledge about each others skills, previously joint training periods, and organization and performance of study packages. AnaPath Services is well known for its high level scientic approach serving clients with strategies and solutions to overcome developmental hurdles. The merger enables AnaPath to convert its understanding of toxicology into immediate progression of critical milestones within Research & Development.

Abstract
A series of regulatory studies were carried out to investigate the effects of the FAAH inhibitor BIA 10–2474 on fertility, embryo-fetal toxicity and pre- and post-natal development in rats and rabbits. Despite some reductions in sperm count in rats from 50 mg/kg, there were no major changes in male fertility up to 100 mg/kg. In female rats administered up to GD6, there were increases in pre-implantation loss at 50 and 100 mg/kg but neither post-implantation loss nor early embryonic development was affected. In contrast, when administered to female rats during pregnancy (GD6-GD17), BIA 10–2474 at 75 mg/kg/day reduced food consumption resulting in weight loss, increased post-implantation loss and reduced mean fetal body weight. In rabbits, the same maternal toxicity was seen but there were no effects in this species on post-implantation loss or fetal body weights. There were no teratological effects clearly due to BIA 10–2474 and developmental milestones and behavior of offspring were not affected. When administered during pregnancy and lactation (GD6-PND20), some post-implantation loss was seen from 20 mg/kg/day, but developmental milestones and behavior of the offspring were not affected, although males tended to have lower body weight. Based on these data the NOAEL for parental fertility was established as 50 mg/kg/day, the maternal NOAEL during pregnancy was 25 mg/kg/day in rats and developmental NOAEL was 25 and 75 mg/kg/day in rats and rabbits, respectively. When administered during post-natal development to rats the maternal NOAEL was 6 mg/kg/day. The parental reproductive NOAEL, the NOAEL for viability and growth of the F1 offspring, the F1 parental NOAEL and the F1 reproductive NOAEL were all considered to be 20 mg/kg/day.
Abstract
BIA 10-2474 is a novel fatty acid amide hydrolase (FAAH) inhibitor developed for the treatment of medical conditions which would benefit from enhanced levels of endogenous anandamide (AEA) such as pain disorders. During a Phase I clinical trial one subject died after receiving BIA 10-2474 and four other subjects displayed neurological signs. As part of series of papers presenting all the toxicology data available prior to the clinical trial, we report here the preclinical toxicology studies examining once-a-day oral administration of BIA 10-2474 to male and female Wistar rats. These included a 14-day dose range finding (150, 200 and 250 mg/kg/day), a 4-week study (30, 90 and 150 mg/kg/day) and 13- and 26-week studies (both at 10, 30 and 90 mg/kg/day). The 13- and 26-week studies also included a 4-week recovery arm and a toxicokinetic arm for the parent compound, BIA 10-2474, and the two major metabolites (BIA 10-2445 and BIA 10-2583) were also measured in the 26-week study. At 150 mg/kg and below, all animals survived the scheduled treatment periods although neurological side-effects (abnormal or stiff gait, dragging of fore- or hind-limbs) were seen at 150 mg/kg in both the dose-range finding and 4-week studies. At 90 mg/kg/day, even up to 26-weeks treatment, no clinical signs were seen apart from some decreases in body weight gain. A number of consistent hematological and biochemical changes were noted which were considered related to treatment with BIA 10-2474. Morphologically, in the 4-week study, except for a slight gliosis in the hippocampus of one female at 150 mg/kg, no CNS histopathology was observed; hippocampus gliosis was not observed in subsequent studies. In the 13-week study axonal swelling was present in the medulla oblongata in about half the animals at 90 mg/kg/day and this increased to nearly all the rats at 90 mg/kg/day in the 26-week study. Additional signs seen only in the 26-week study at 90 mg/kg/day included axonal swelling of the fasiculus gracilis and vacuolar changes in the medulla oblongata and ventral commissure of the 3rd ventricle. Other findings included vacuolar degeneration in the ganglia of the GI tract, salivary glands, prostate gland, uterus, and parathyroid glands. The pituitary gland showed edema and mitotic figures in the pars nervosa. These observations outside the CNS were seen in most rats at 90 and 150 mg/kg/day independent of study duration. At 30 mg/kg/day, most of these observations were only seen in isolated cases except for the vacuolar degeneration in GI tract ganglia, which was absent at this dose after 4 weeks treatment but was present in almost all rats at 13 and 26 weeks. Hepatocellular hypertrophy and nephropathy were seen across all studies and the extent of these changes was similar in the 13- and 26-week studies. Most findings resolved after the 4-week recovery periods except for the axonal swelling seen in the medulla oblongata and spinal cord. BIA 10-2474 exposure was markedly higher than the exposure to either metabolite, BIA 10-2445 (19- to 192-fold) and BIA 10-2583 (63- to 526-fold). Exposure to metabolites differed between sexes with higher concentrations of BIA 10-2445 in females compared to males, but the inverse for BIA 10-2583. Although a No Observed Adverse Effect Level (NOAEL) of 30 mg/kg/day was concluded following the 4-week study, the histopathological findings at that dose in the 13- and 26-week studies resulted in the NOAEL being determined to be 10 mg/kg/day.
