Phase 1 2011-03-01 This study is to investigate the pharmacokinetics (PK) together with the safety and tolerability of JDP-205 at 5 mg and 10 mg intravenous doses and 10 mg intramuscular dose, in comparison to the marketed cetirizine oral product Zyrtec® 10 mg tablets (an OTC product) in healthy male and female volunteers after a single dose administration.
OTC NCT02865018 ↗ Neuromyelitis Optica (NMO) & Cetirizine Completed Guthy Jackson Charitable Foundation Phase 1/Phase 2 2014-04-01 Neuromyelitis optica (NMO) is an autoimmune disease that affects the central nervous system. Patients have relapses (also known as attacks) which are often quite severe and leave them with significant disability. Without treatment, within 5 years 50% of NMO patients are blind in one or both eyes or require walking assistance (cane, walker or wheelchair). NMO has only been relatively recently described and is fairly rare. Most NMO patients' immune systems produce abnormal antibodies against aquaporin-4 (AQP4), which is found in certain cells in the central nervous system. When these AQP4 antibodies bind to AQP4, they trigger a cascade of events involving the immune system which eventually leads to damage to the nervous system. This ultimately leads to disability, some of which is permanent. Until now, treatments for NMO have been mostly focused on decreasing production of this AQP4 antibody. However, recent experiments in animal models of NMO have shown the importance of what happens inside the central nervous system after the antibody binds to the nervous system cell. Specifically, researchers have noted the importance of a specific cell type, eosinophils, in causing damage in NMO lesions. In a recent study, researchers showed they could prevent damage from NMO by blocking eosinophils using cetirizine, which is a popular over-the-counter allergy medicine. Cetirizine is already known to be safe and well-tolerated in the general population. In this study, the researchers plan to add cetirizine on to patients' current NMO treatment. The researchers aim to show that it is safe, well-tolerated, and that with cetirizine, NMO patients have less relapses and therefore less disability over the course of the year following initiation of treatment. The researchers also plan to study how cetirizine changes the immunological profile in NMO patients by examining blood and cerebrospinal fluid.

NCT00150761 ↗ Facial Thermography Study of Levocetirizine Versus Cetirizine Completed UCB Pharma Phase 4 2004-07-01 Phase IV, human pharmacology, exploratory, randomized, 3-way (3 treatment periods) cross-over, double blind, double dummy, placebo controlled study to compare levocetirizine and cetirizine by means of IR thermography.
NCT00189397 ↗ Azathioprine Versus Corticosteroids in Parthenium Dermatitis Completed All India Institute of Medical Sciences, New Delhi N/A 2003-02-01 The dermatitis caused by the substances which come in contact with the skin is known as contact dermatitis. When such a reaction is caused by the agents suspended in the air, it is called air-borne contact dermatitis (ABCD). Parthenium hysterophorus at present is the commonest cause of ABCD in India though in some cases other plants have also been found to cause ABCD. Parthenium dermatitis is one of the major health problems in dermatology in our country. Though it has very little mortality, the disease normally continues to persist with variable remissions and relapses causing great distress and morbidity. Corticosteroids, topical and systemic have been the mainstay of the treatment so far. Therefore, the patients with ABCD who have to take corticosteroids for long periods of time tend to develop severe and sometimes irreversible side effects of the therapy. Azathioprine is an immunosuppressive drug which acts by inhibiting the T lymphocytes. In our previous studies we have been able to induce remissions in these patients with azathioprine used as daily as well as monthly bolus dose, without having to use systemic corticosteroids. The side effect with azathioprine in these studies were almost absent. We have therefore planned to study the therapeutic efficacy of azathioprine weekly pulse doses versus daily azathioprine in achieving remissions in patients having Parthenium dermatitis and to monitor the side effects of both the regimens.
