Abstract
OBJECTIVE A previous 12-month comparative trial with Criscy™ (r-hGH Cristália), a biosimilar recombinant growth hormone, demonstrated equivalent efficacy and safety to Genotropin™. This extension trial evaluated the effects of switching patients treated with Genotropin™ to the biosimilar Criscy™ over an additional 6-month treatment period, comparing efficacy, safety, and immunogenicity parameters with patients remaining in the Criscy™ arm. DESIGN This extension study included 11 research centers and 81 patients who participated in the CERES study (Czepielewski et al., 2019 [1]). Participants from the Genotropin™ arm (n = 39) had the drug replaced by Criscy™ and the remaining participants were kept in the Criscy™ arm (n = 42) for an additional 6-month period to evaluate immunogenicity, efficacy (growth rate, height SDS), and safety (laboratory tests, and adverse events). RESULTS Before the switch, both Criscy™ and Genotropin groups were similar concerning demographics, and auxological measures: age, sex, height, height SDS, weight, and BMI. Height velocity (HV) after 18 months of treatment was 8.7 ± 1.56 cm/year for Criscy™ group and 8.9 ± 1.36 cm/year for Genotropin™ group in the ITT population (p = 0.43). The auxological parameters and IGF-1 and IGFBP-3 SDS were comparable between both groups of patients. No participants were excluded from the study due to adverse events. There were no clinical or statistical relevant differences between the treatment groups concerning frequency, distribution, intensity, and AEs outcome. Similarly, no new anti-r-hGH (ADA) cases among patients that switched from Genotropin™ to Criscy™ were reported. No neutralizing antibody (nAb) was detected in either group. CONCLUSIONS This trial showed that switching from originator recombinant human growth hormone to Criscy™ had no impact on efficacy, safety, nor immunogenicity as compared to continued treatment with Criscy™. Growth rates and ADA incidence remained the same as seen before the switch.

Abstract
OBJECTIVE The CERES study was a randomized, multicenter, investigator-blind trial aimed to evaluate the efficacy and safety of a recombinant human growth hormone (r-hGH) developed by Cristalia, as a biosimilar product, with analytical, functional and pharmacokinetics similarities comparable to Genotropin™, in children with growth hormone deficiency (GHD). DESIGN A total of 135 naïve prepubertal children with GHD were recruited, of whom 97 were randomized in 14 Brazilian sites to received either r-hGH Cristalia (n = 49) or Genotropin™ (n = 48). Efficacy was evaluated considering the height standard deviation score (SDS) and growth velocity as auxological parameters, IGF-1 and IGFBP-3 were measured as pharmacodynamic parameters during 12 months treatment time. Safety was assessed by monitoring adverse events, immunogenicity, blood count with platelets, biochemical profile and hormonal levels particularly fasting glucose, insulin and HbA1C. RESULTS The auxological parameters and IGF-1 and IGFBP-3 levels were comparable between both groups of patients. At end of study or the 12th month treatment, the means growth velocity was 9.7 cm/year and 9.5 cm/year, for r-hGH Cristalia and Genotropin™, respectively. The ANCOVA mean difference between the groups was 0.16 cm/year to Cristalia group (CI 95% = -0.72 to 1.03 cm/year). There was no difference in adherence among the treatment groups. The safety profile was comparable between groups. CONCLUSIONS The clinical similarity between r-hGH and Genotropin™ was demonstrated within 12 month of treatment. On the basis of comparability of quality, safety, and efficacy to the reference product, r-hGH from Cristalia can be considered a cost-effective therapeutic option for patients with growth disorders.

Abstract
The solubilisation of polar and polyphenol antioxidant in vegetable oils was studied. It was shown that the use of a polyglyceryl-3-diisostearate (PG3DS), a bio-sourced emulsifier well known in cosmetics, increases the yield of solubilisation thanks to some aggregation properties analysed using x-ray scattering technique. We show indeed that PG3DS forms reverse aggregates with a critical concentration that depends on the oil polarity. PG3DS reverse aggregates are elongated with a polar core and cannot be really swollen by addition of water. This supramolecular organisation allows however an efficient solubilisation of polar antioxidants in vegetable oils.

Abstract
Two decades ago, clinical trials were carried out only in developed countries. Drug development and the need to speed up clinical trials lead the conduction of clinical trials to other countries. Among the regions of interest, Latin America (LA) has played its role successfully. LA has a large number of naive patients, qualified investigators, established regulatory systems and reasonable costs. Furthermore, LA might be also considered as a new option for any company looking for international patterns on drug research and development. The region has good professionals with scientific qualifications, well-established multinational pharmaceutical bases and an expansive pharmaceutical regional market. This work summarizes the recent advances that have occurred in drug research and development in the region and the expansion of the clinical trial market in the last couple of years.

Abstract
A mixture of aluminum salts and natural polyelectrolytes, extracted from the cactus Opuntia ficus indica, has been used for cleaning of wastewater from poultry slaughterhouse. The aggregation and settling properties of colloids and complex organics such as oil, grease, fats, proteins, and suspended solids, was increased if compared with conventional methods of wastewater treatment using only aluminum or iron sulfate. A mixture of aluminum salt in a concentration range of 300 to 600 mg l(-1) and natural polyelectrolytes of 0.6 to 0.8 mg l(-1) was used for flocculation and coagulation. The combination of coagulant and natural polyelectrolytes was able to remove chemical oxygen demand (86%), oil and grease (93%), turbidity (89%), and suspended solids (93%). Methanization activity was also investigated for the effluents in natura.
