В исследовании IMPACT SHPT (Идентификационный код на сайте ClinicalTrials.gov: NCT00977080) сравнивали 2 схемы лечения ВГПТ, направленные на контроль уровня интактного паратгормона (иПТГ) у пациентов на диализе: 1) терапии на основе парикальцитола с титрованием дозы и добавлением цинакальцета (только в случае развития гиперкальциемии); 2) терапия на основе комбинации цинакальцета и низких доз витамина D. ПАЦИЕНТЫ И МЕТОДЫ. В этом 28-недельном многоцентровом открытом исследовании 4 фазы участников рандомизировали в группу лечения парикальцитолом либо цинакальцетом в сочетании с низкими дозами витамина D. Рандомизация и анализ были стратифицированы в зависимости от способа введения парикальцитола (внутривенно или внутрь). Первичной конечной точкой по эффективности определена доля пациентов, у которых был достигнут средний уровень иПТГ 150–300 пг/мл в течение 21–28 нед. РЕЗУЛЬТАТЫ. Из 272 участников рандомизированного исследования 268 получили хотя бы одну дозу исследуемого препарата. В первичный анализ был включён 101 пациент из группы внутривенного введения и 110 больных из группы перорального приема с одним и более значений на 21–28-й неделях. При внутривенном введении первичная конечная точка была достигнута у 57,7% участников группы парикальцитола по сравнению с 32,7% пациентов группы цинакальцета (p=0,016). В группе перорального приёма соответствующие доли пациентов составили 54,4% при лечении парикальцитолом и 43,4% на фоне терапии цинакальцетом (p=0,260). Различия в частоте достижения иПТГ 150–300 пг/мл в течение 21–28 нед целевого со стратификационной поправкой на исследование (тест Cochran-MantelHaenszel) подтвердили общее преимущество парикальцитола (56,0%) перед цинакальцетом (38,2%; p = 0,010). Гиперкальциемия возникла у 4 (7,7%) и (0%) пациентов, получающих парикальцитол в/в и внутрь соответственно. При лечении цинакальцетом гипокальциемия отмечена у 46,9 и 54,7% участников «внутривенной» и «пероральной» групп соответственно. ЗАКЛЮЧЕНИЕ. Парикальцитол по сравнению с цинакальцетом в сочетании с низкими дозами витамина D обеспечивал лучший контроль иПТГ, при сохранении низкой частоты гиперкальциемии.</p><sec><title>Благодарности</title><p>Благодарности.

Optimal treatment for secondary hyperparathyroidism (SHPT) is not defined nowadays. The IMPACT SHPT (ClinicalTrials.gov identifier: NCT00977080) research compared 2 treatment regimens of SHPT for intact parathyroid hormone (iPTH) level control in patients receiving haemodialysis: 1) therapy based on dose-titrated paricalcitol with cinacalcet (only for hypercalcaemia); 2) therapy based on coombination of cinacalcet with low-dose vitamin D. PATIENTS AND METHODS. In this 28-week, multicentre, open-label Phase 4 study, participants were randomly selected to receive paricalcitol or cinacalcet with low-dose vitamin D. Randomization and analysis were stratified by paricalcitol injection method [intravenous (IV) or oral]. The primary efficacy end point was the proportion of subjects who achieved medium iPTH level of 150-300 pg/mL during Weeks 21–28. RESULTS. Of 272 subjects of randomized research, 268 received one or more dose of study drug. 101 patients from group with IV injection and 110 from group of oral administration with one or more values during Weeks 21-28 were included in the primary analysis. In IV injection, 57.7% of subjects in the paricalcitol group versus 32.7% in the cinacalcet group (P = 0.016) achieved the primary end point. In the oral administration group, the corresponding proportions of subjects were 54.4% for paricalcitol treatment and 43.4% for cinacalcet therapy (P = 0.260). Cochran-Mantel-Haenszel test, controlling for stratum, revealed overall superiority of paricalcitol (56.0%) over cinacalcet (38.2%; P = 0.010) in achieving iPTH 150-300 pg/mL during Weeks 21-28. Hypercalcaemia occurred in 4 (7.7%) and 0 (0%) of paricalcitol-treated subjects in the IV and oral administration, respectively. Hypocalcaemia occurred in 46.9% and 54.7% of cinacalcet-treated subjects in the IV and oral administration, respectively. CONCLUSION. Paricalcitol versus cinacalcet with low-dose vitamin D provided superior control of iPTH, with low incidence of hypercalcaemia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цинакальцета гидрохлорид</kwd><kwd>парикальцитол</kwd><kwd>вторичный гиперпаратиреоз</kwd><kwd>болезнь почек</kwd><kwd>гемодиализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cinacalcet hydrochloride</kwd><kwd>paricalcitol</kwd><kwd>secondary hyperparathyroidism</kwd><kwd>kidney disease</kwd><kwd>haemodialysis</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rodriguez M, Nemeth E, Martin D.
