Joint Experience

Tumors of the female reproductive system are among the five most common cancers in women worldwide. Up to 60 % of these patients require chemotherapy to reduce the risk of recurrence. Currently, an additional treatment option is available for patients with advanced cancers of the female reproductive system, namely vascular endothelial growth factor inhibitor bevacizumab. To assess the efficacy and safety of Avegra®, Russian generic of bevacizumab, we summarized the experience of 5 specialized healthcare institutions that used it for the treatment of 178 patients with tumors of the female reproductive system. The analysis of side effects in 1,074 treatment cycles demonstrated that Avegra® had a good safety profile. Clinical effects of Avegra® were similar to those of the original drug.

The retinopathy of prematurity (ROP), a neovascular retinal disorder presenting in premature infants, is the leading causes of blindness in children. Currently, there is no approved drug therapy for ROP in the U.S., highlighting the urgent unmet clinical need for a novel therapeutic to treat the disease. Secretogranin III (Scg3) was recently identified as a disease-selective angiogenic factor, and Scg3-neutralizing monoclonal antibodies were reported to alleviate pathological retinal neovascularization in mouse models. In this study, we characterized the efficacy and safety of a full-length humanized anti-Scg3 antibody (hAb) to ameliorate retinal pathology in oxygen-induced retinopathy (OIR) mice, a surrogate model of ROP, by implementing histological and functional analyses. Our results demonstrate that the anti-Scg3 hAb outperforms the vascular endothelial growth factor inhibitor aflibercept in terms of efficacy and safety to treat OIR mice. Our findings support the development of anti-Scg3 hAb for clinical application.

ZusammenfassungDer VEGF(„vascular endothelial growth factor“)-Inhibitor Brolucizumab ist seit Oktober 2019 in den USA und seit Februar 2020 in Europa zur Behandlung der neovaskulären altersabhängigen Makuladegeneration (nAMD) zugelassen. Grundlage der Zulassung bildeten die randomisierten, doppel-blinden Phase-III-Studien HAWK und HARRIER mit insgesamt 1817 Patienten. Hierbei zeigte Brolucizumab 6 mg (je nach Krankheitsaktivität alle 12 oder alle 8 Wochen verabreicht) eine nichtunterlegene Wirksamkeit in Bezug auf den bestkorrigierten Visus gegenüber Aflibercept 2 mg (alle 8 Wochen verabreicht). Erste Rückmeldungen zum Einsatz von Brolucizumab nach der Marktzulassung in den USA haben einzelne, z. T. schwerwiegende Fälle behandlungsassoziierter intraokularer Entzündungen mit retinaler Vaskulitis und/oder retinaler, vaskulärer Okklusion beschrieben, die teilweise zu einem schweren Visusverlust führten. Die Daten der Zulassungsstudien wurden daraufhin durch ein Safety Review Committee (SRC) unabhängig retrospektiv analysiert. Ziel der vorliegenden Publikation ist es, Anwendern eine Orientierungshilfe aus Autorensicht bei der Therapie einer Brolucizumab-assoziierten intraokularen Entzündung zu bieten. Von zentraler Bedeutung ist hierbei auch eine erweiterte Aufklärung der Patienten über Symptome einer intraokularen Entzündung. Obwohl die Fallserien und die HAWK/HARRIER-Daten es nicht abschließend beantworten, bleiben eine zu späte Detektion, eine unterdosierte antientzündliche Therapie oder eine unbedachte Wiederbehandlung mit Brolucizumab dem Verdacht ausgesetzt, Komplikationen zu verstärken. Ein Stopp der Brolucizumab-Therapie sollte grundsätzlich erfolgen, sobald es nach Gabe des Medikaments zu intraokularen Entzündungen mit oder ohne retinalen Vaskulitiden und oder Gefäßverschluss kam. Abhängig vom Schwerpunkt der Entzündung werden dem Behandler an die Leitlinien und Stellungnahmen angelehnte Empfehlungen für Diagnostik und Therapie dargestellt.

Purpose. To present a rare clinical case of bilateral Coates retinitis in a 5-year-old girl. Material and methods. A clinical case of a 5-year-old girl with rare Coat's retinitis in both eyes is described. The disease occurred abruptly: the child's parents noted the appearance of leukocoria in the right eye. After the examination Coates ' retinitis was diagnosed. At the time of examination in the clinic, there was a retinal detachment in the right eye, the surgical treatment was performed: lensvitrshvartectomy, plastic surgery of the anterior chamber, with the melting of the retina with perfluoroorganic compounds, drainage of subretinalfluid, endolaser coagulation on the right eye. A month after the first symptoms appeared in the right eye, the patient complained of decreased vision in the left eye. Examination on the pediatric retinal camera showed an increase in vascular activity in the left eye, and signs of Coats' retinitis were revealed. Results. As a therapy for this disease, the patient was twice injected intravitreally inhibitor of vascular endothelial growth factor (VEGF inhibitor) into the left eye with positive dynamics noted as a decrease in the activity of retinal vessels and leveling of the exudative component, as well as with an increase in visual acuity in the left eye. Conclusion. This clinical case demonstrates that intravitreal administration of inhibitor VEGF with traditional methods of treatment can be used as a treatment for patients with Coates retinitis. Key words: Coat's retinitis, Coats' disease, vascular endothelial growth factor inhibitor, aflibercept, intravitreal injection, anti-VEGF, retinal detachment.

There has been an intensive effort to develop novel therapies for the treatment of metastatic colorectal cancer (mCRC). The anti-epidermal growth factor receptor (EGFR) antibodies panitumumab and cetuximab and the anti-vascular endothelial growth factor (VEGF) antibody bevacizumab have demonstrated clinical efficacy and acceptable toxicity in the treatment of mCRC as single agents or in combination with chemotherapy. Recent clinical trials have explored the efficacy and safety of treatment regimens incorporating chemotherapy in combination with bevacizumab and either panitumumab or cetuximab in patients with mCRC. Results from the BOND-2 trial, which investigated cetuximab, bevacizumab, and chemotherapy in mCRC, provided support for this therapeutic approach. Two large randomized phase 3 trials were initiated to evaluate firstline treatment of mCRC. The Panitumumab Advanced Colorectal Cancer Evaluation (PACCE) study investigated the efficacy and safety of oxaliplatin- or irinotecan-based chemotherapy and bevacizumab with or without panitumumab; CAIRO2 assessed the efficacy and safety of capecitabine/oxaliplatin and bevacizumab with or without cetuximab. In both trials, the combination of bevacizumab, an EGFR-specific antibody, and chemotherapy in first-line treatment of mCRC was associated with increased toxicity and no improvement in patient outcome. These results suggest that these specific combinations should not be used in first-line mCRC outside investigational studies.
