This trial is evaluating whether iptacopan will improve 1 primary outcome and 5 secondary outcomes in patients with C3G. Measurement will happen over the course of 6 months (double-blind).
This trial requires 68 total participants across 2 different treatment groups
This trial involves 2 different treatments. Iptacopan is the primary treatment being studied. Participants will all receive the same treatment. Some patients will receive a placebo treatment. The treatments being tested are in Phase 3 and have had some early promising results.
Patients with C3G have symptoms of depression, irritable bowel syndrome, and, more commonly, other neurologic symptoms. Depression can precede the onset of neurological manifestations, and therefore, is considered an early presentation of the disorder.
Iptacopan has low-to-moderate clinical effectiveness in the treatment of pain, and its tolerability appears to be acceptable. Although parecoxib has fewer adverse events, it appears to be ineffective in this study.
The present studies provide evidence that the C-3G allele is associated with increased production of C3G and that the high amounts of C-3G in normal tissue observed in non-melanomas indicate synthesis from a precursor of the C-4A type. An excess of C-3G is therefore unlikely to play any role in the development or progression of cutaneous melanoma and nevi.
The c3g gene is responsible for over 90% of the genetic variance in the common occurrence of C3G in human populations. C3G is one of the strongest genetic predisposing factors for developing rheumatoid arthritis and other joint conditions.
As well as having the first published description of anti-neutrophil cytoplasmic antibodies, we describe a new form of the complement, the C3 component (C3g). We show for the first time that it is widely distributed in the blood of healthy individuals and in patients with systemic autoimmune disorders including C3 nephritic syndrome. We also show that it acts functionally in healthy individuals by inducing neutrophil recruitment during antigen/antibody-induced inflammation, and suggest that C3g may be a new biomarker in systemic inflammatory disorders.
The use of the common treatments of c3g is relatively limited, and the quality of the research on the common treatments of c3g is relatively low. Data from a recent study reveals that a relatively high number of treatments are used to treat C3g at the hospital, and that the current state of knowledge is still limited.
C3g is no longer a neglected, benign disease. It should be regarded as an integral part of the autoimmune diseases. It may induce symptoms as well as the underlying disease process.
Overall, there were no common adverse effects of iptacopan observed in a subset of patients who received at least 800 mg of iptacopan in a 3-week treatment period in a 24-hour observation period. One such common adverse event (nausea) was more frequent among subjects treated with iptacopan than with placebo. More study is needed to determine if a link exists between atypical antipsychotic-induced tardive dyskinesia and any side effect. Side effects were transient in most individuals.
Iptacopan had an efficacy similar to that of a placebo (i.e., no significant difference between the two interventions) regardless of the intensity of the C3G infusion during the ISR. The ISR intensity was highly sensitive to the timing of the C3G infusion relative to the start of the ISR.
Genetic predisposition to disease is a common finding, which may help to explain the high prevalence of the genes found in the study. However, such findings will probably not be exploited to develop new diagnostic tests for familial forms of the disease.
Patients with c3g are mostly female and have a worse clinical course than those without. Results from a recent paper we tried to identify patient subsets for clinical trials of c3g.
Iptacopan is a peripherally acting opioid/opiate analgesic drug and analgesic with sedative and anticonvulsant properties. A single dose of iptacopan was administered via intravenous injection to patients with acute pain of malignant origin.
