All Rights Reserved The study included patients with polymerase chain reaction assay–confirmed SARS-CoV-2, an oxygen saturation <90% without supplemental oxygen, a computed tomography severity score ≥7, and a requirement of ≥3 L/min of supplemental oxygen. 1 Note: COVID-19 studies only listed on the World Health Organization's International Clinical Trials Registry Platform are not counted in these tables. ), and Institut für Medizinische Statistik und Epidemiologie (A.H., V.K. Covaxin, India’s first COVID-19 vaccine, has demonstrated an interim clinical efficacy of 81% in the phase 3 clinical trial, vaccine maker Bharat Biotech said on Wednesday. In total, 10 patients were included in this study and treated with 3 doses of 30 mg icatibant via subcutaneous injection at 6-hour intervals. The results were similar when patients assessed local injection-site reactions (Table S3 in the Supplementary Appendix). The maximum recorded time to the complete resolution of edema (61.2 hours) was used to replace the data for these three patients in the primary efficacy analysis. Clinical trials use volunteers, who agree to participate in these types of studies. Clinical trials offer hope for many people and provide an opportunity to … The number and percentage of patients who required rescue intervention and the number and extent of adverse events were compared between the groups with the use of Fisher’s exact test. All 27 patients in the per-protocol population had complete resolution of edema. IMPORTANT : Listing a study does not mean it has been evaluated by the U.S. Federal Government. SARS-CoV-2 enters cells via angiotensin-converting enzyme 2 (ACE2), which is involved in degrading kinin des-Arg9-bradykinin. Enjoying our content? ), 16. - Drug Monographs After 3 injections of icatibant, 4 (44%) patients were no longer dependent on oxygen supplementation within 10 to 35 hours. 2 Note: Standardized drug names automatically assigned by the National Library of Medicine based on drug names provided by the Responsible Party. Share this article. All the patients in the per-protocol population had complete resolution of edema; however, three patients in the standard-therapy group required rescue therapy (icatibant and prednisolone) and were classified as having had treatment failure. Investigators who were unaware of the treatment assignments also assessed the severity of the same six symptoms at the same time points, using a scale from 0 (no symptoms) to 3 (severe symptoms); a composite symptom score was calculated from the average of the six symptom scores. Secondary end points included the proportion of patients who did not have a response to treatment (i.e., patients who required rescue therapy); the proportion of patients with complete resolution of edema at 4 hours after treatment; the time to the onset of symptom relief, which was defined as the time to the first improvement (i.e., decrease) of at least one point in the composite score of the investigator-assessed symptom score, the angioedema score, or the score on the patient-assessed visual-analogue scale; and the composite and individual investigator-assessed symptom scores, angioedema scores, and scores on the patient-assessed visual-analogue scale, as well as the change in the composite scores from the pretreatment scores, at each protocol-specified time point. Assuming a maximum dropout rate of 25% (to account for patients requiring rescue intervention for progression of edema), a final sample of 15 patients in each treatment group was planned. Given these assumptions, we calculated that with 11 patients in each group, the study would have 90% power to detect the expected between-group difference in distribution with respect to the time to complete resolution of edema, at a two-sided significance level of 5%, with the use of a Wilcoxon rank-sum test. According to investigator assessments, all injection-site reactions resolved completely within 4 hours after treatment. Seven patients in the icatibant group and two in the standard-therapy group had pain on administration of treatment, as reported by the investigators (Table 3). The median time to complete resolution was 8.0 hours (interquartile range, 3.0 to 16.0) with icatibant as compared with 27.1 hours (interquartile range, 20.3 to 48.0) with standard therapy (P=0.002). The results were similar when patient-assessed symptom scores were used. Similar results were observed with respect to the composite investigator-assessed angioedema score; the area under the curve at 12 hours was 6.6 (range, 3.0 to 18.7) in the icatibant group as compared with 8.9 (range, 2.8 to 24.0) in the standard-therapy group. There is no approved treatment for this potentially life-threatening condition. Hospitals are allegedly hiring middlemen and agents for arranging volunteers for clinical trials of Covid-19 vaccines. Clinical data from phase 3 trials show the vaccine is 66 per cent effective at preventing moderate to severe Covid-19 but offers high protection against people needing to go to hospital. Any critically ill patient with known or presumed COVID-19 will be automatically entered into the screening phase of the trial until SARS-CoV-2 infection is confirmed. The baseline characteristics of the per-protocol population are shown in Table 1. ... Ball hopes that with this, the clinical trials of the vaccine could be initiated soon. Five patients (38%) who received icatibant, as compared with none who received standard therapy, had complete resolution of edema within 4 hours after treatment (P=0.02). Therefore, this case-control study investigated whether treatment with the bradykinin 2 receptor antagonist icatibant could be used as a treatment strategy in patients with COVID-19. Studies in animals as well as studies involving humans have shown that blocking bradykinin B2 receptors attenuates the efficacy of ACE inhibitors.19,20 Icatibant is therefore a logical treatment choice for ACE-inhibitor–induced angioedema. In phase 3 studies of icatibant in patients with hereditary angioedema, the median time to almost-complete symptom relief was similar (8.5 to 10 hours).11, We also observed a significantly faster time to the onset of symptom relief with icatibant than with standard therapy (P=0.03).

READ: Janssen starts COVID-19 vaccine trials in PH— DOST “Baka maging mas mataas ang efficacy nila o baka mas tumagal ang kanilang efficacy. Patient-assessed scores followed the same pattern. Baricitinib Plus Remdesivir Cuts Time to Recovery for Hospitalized COVID-19 Patients. These events were transient and resolved in 87% of the patients (13 of 15) within 4 hours after administration of the study drug. Other exclusion criteria were a history of angioedema before the initiation of ACE-inhibitor therapy, acute urticaria, unstable angina, acute myocardial ischemia, acute heart failure with a New York Heart Association class of III or IV, pregnancy, and lactation. For 9 patients who received icatibant, 2 matched control patients admitted before approval of this treatment were selected; 1 patient who received icatibant was discharged on day 7, and no matched control was identified. Manders K, van Deuren M, Hoedemaekers C, Simon A. Bradykinin-receptor antagonist icatibant: possible treatment for ACE inhibitor-related angio-oedema. Neth J Med 2012;70:386-387, 13. Asphyxia due to angiotensin converting enzyme (ACE) inhibitor mediated angioedema of the tongue during the treatment of hypertensive heart disease. ACE inhibitors exert their therapeutic effects by blocking the conversion of angiotensin I to angiotensin II; they also inhibit the breakdown of bradykinin, thereby increasing its activity. Indeed, the French National Center for Angioedema recently recommended first-line off-label use of bradykinin antagonists and second-line use of C1-inhibitor concentrates in patients with ACE-inhibitor–induced angioedema.21 However, icatibant is not currently licensed for this indication. ), Klinikum rechts der Isar, Technische Universität München, and the Department of Otorhinolaryngology, Grosshadern Medical Center of the University of Munich (K.S., M.H. Significantly more patients in the icatibant group than in the standard-therapy group had complete resolution of edema within 4 hours after treatment (5 of 13 vs. 0 of 14, P=0.02). The study design is shown in Figure S1 in the Supplementary Appendix, available at NEJM.org. In four trials that we conducted, we tested for human coronaviruses, but only composite viral endpoints were reported in the trials. To reduce regulatory burden, we have developed a new regulatory pathway, the interim order for clinical trials for medical devices and drugs relating to COVID-19 . In the icatibant group, the only patient-reported adverse event was pain at the injection site. There was no clear association with D-dimer concentrations and fever. Peer-reviewed journal featuring in-depth articles to accelerate the transformation of health care delivery. We hope you’re enjoying the latest clinical news, full-length features, case studies, and more. Dasarathy Y, Lanzillo JJ, Fanburg BL. In this randomized trial involving patients with ACE-inhibitor–induced angioedema, complete resolution of edema occurred significantly more quickly after treatment with 30 mg of subcutaneous icatibant than after standard therapy with glucocorticoids and antihistamines. Clinical profile of angioedema associated with angiotensin converting-enzyme inhibition. Stimulation of bovine pulmonary artery endothelial cell ACE by dexamethasone: involvement of steroid receptors. Although the causal role of bradykinin in ACE-inhibitor–induced angioedema is not yet completely understood, ACE is the most important enzyme regulating the breakdown of bradykinin in plasma and tissues. Suzi Ring. For patients who did not have a response to treatment (i.e., patients who required administration of rescue intervention), the time to the complete resolution of edema was set to the longest observed resolution time in the per-protocol study population.

Published Wed, Feb 24 2021 4:05 PM EST Updated Wed, Feb 24 2021 6:57 PM EST. The primary end point was the time to the complete resolution of edema after administration of the study treatment, as evaluated on the basis of investigator-assessed and patient-assessed symptom scores, as well as the investigator’s assessment of the severity of angioedema on the basis of the physical examination. Three patients receiving standard therapy required rescue intervention with icatibant and prednisolone; 1 patient required tracheotomy.
