Active clinical trials for "Hypersensitivity"

The investigators here want to test the hypothesis that a total period of 18 months of gradual open introduction of a certain egg product with regard to full egg tolerance induction is not inferior when compared to a total period of 30 months gradual open introduction of a certain egg product (see steps for the specific egg products) after tolerance for baked egg has been obtained. The investigators also want to define step-specific 'tolerance-failures' and study the relevance of specific IgE to specific egg components to predict failures at each step.

Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders, with a global prevalence of 11% according to a recent meta-analysis. The total cost of managing IBS in the United States is in excess of $30 billion per year, including indirect costs relating to loss of productivity of more than $20 billion. Abdominal pain/discomfort (i.e. visceral hypersensitivity) is present in all patients with IBS and remains the most therapy-resistant symptom. Apart from abdominal pain, which is measured subjectively using visual scales, several studies have shown a significant increase in rectal sensitivity, which is measured objectively using an inflatable balloon. Drugs which are shown to have objective effects on visceral hypersensitivity are crucial in the management of IBS. While certain drugs have shown to decrease abdominal pain, there is very little data to substantiate objective changes in visceral hypersensitivity. Rifaximin is a poorly absorbed antibiotic and the exact underlying mechanism of action for rifaximin in reducing the pain component of IBS remains unknown. However, rifaximin has been shown in randomized controlled trials to decrease abdominal discomfort in all subtypes of IBS. The investigators hypothesize that rifaximin is effective in decreasing rectal visceral hypersensitivity in IBS patients. In this study, the investigators propose to test this hypothesis by measuring visceral hypersensitivity using the graded balloon distention test, before and after a course of rifaximin. To test whether this effect is accompanied by treating SIBO, the investigators will also perform lactulose breath tests before and after rifaximin therapy.

The primary objectives of this study are: To evaluate the efficacy of glufosfamide in subjects with extensive recurrent sensitive small cell lung cancer (SCLC) as measured by objective response rate To evaluate the safety of glufosfamide in subjects with extensive recurrent sensitive SCLC The secondary objectives are: To evaluate the efficacy of glufosfamide in subjects with extensive recurrent sensitive SCLC as measured by duration of response, progression-free survival and overall survival To evaluate the pharmacokinetics of glufosfamide and isophosphoramide mustard (IPM) The exploratory objectives of this trial are: To evaluate the effect of glufosfamide on lung cancer symptoms To evaluate the role of tumor cell glucose transporter expression on the efficacy of glufosfamide

This study is a two-part Phase 1b/2a First-in-Human (FIH) randomized, double-blind, placebo-controlled clinical trial to assess the safety, tolerability, pharmacodynamics, and efficacy of multiple ascending doses of CNP-201 in Part A, with the goal of identifying a safe and tolerable dose level to be evaluated further in a larger number of subjects in Part B.

Hypothesis: the effectiveness of treatment of Pompe disease with rhGAA enzyme replacement therapy (ERT) is limited at least in part because patients develop antibodies against the provided rhGAA enzyme. Treatment with Zavesca® prior to infusion may dampen or eliminate the anti-rhGAA immune response in patients receiving ERT, thereby allowing for greater ERT efficacy. Treatment with Zavesca® before a enzyme replacement therapy (ERT) may decrease the severity of, or eliminate infusion associated reactions (IAR) in people with Pompe Disease receiving ERT.

This is a multicenter, controlled, randomized, prospective, non-inferiority, double blind intervention trial to evaluate the children growth (at 6, 9 and 12 months) using a rice hydrolysed protein formula compared to an extensively cow's milk protein hydrolysed formula for the management of Cow's Milk Protein Allergy (CMPA).

The questions proposed by this study are those of safety and efficacy. Concerning safety: "Are sublingual food drops (SLIT) safe enough to be used for stimulation of natural immune suppression in patients with food allergies?" Concerning efficacy: "Do the drops suppress food allergy enough for patients to eat previously allergic foods with little or no allergic reaction?" The aim of this trial is to provide systematic collection of data proving the safety and efficacy of food drops in the correction of food allergy. A patient's range of symptoms, which can include but are not limited to fatigue, nausea, vomiting, diarrhea, abdominal pain, and insomnia can be diagnostic indicators of food allergies. An approach to answering the above questions can be done by a randomized, controlled, blinded study. The design of our study could be reasonable and powerful because this layout limits bias and accounts for placebo effects: The patients enrolled in our study will present with food allergy symptoms and diagnostic tests will provide the specific information regarding their food allergies. Once the diagnosis has been made and consent for treatment has been obtained, participants will be randomly assigned to either the group that receives the food allergy intervention with SLIT ( food allergens mixed with 50% glycerin in a vial) or the group that receives the control SLIT (glycerin only). The patients are truly blinded to their treatment because all the SLIT food allergy vials are identical and contain no distinguishing features that could reveal their contents. There is also no difference in taste between a vial containing glycerin and food allergens and a vial containing only glycerin. Therefore, a food allergy SLIT randomized-controlled study can be reasonably achieved.

Erlotinib attacks a part of cancer cells that helps them live and grow. Studies done in human beings show that this drug can make a difference in the way anti-estrogens work in hormone-sensitive breast cancers. OSI-906 attacks a different part of the cancer cell that helps them live and grow. Studies done in the laboratory show that OSI-906 can make a difference in the way anti-estrogens work in hormone-sensitive breast cancers.

Efficacy and tolerance of Tegeline® treatment in hypersensitivity syndrome. Immunological study of the T cell index phenotype and functionality in hypersensitivity syndrome.

This is a phase I study using the Erwinia form of asparaginase in place of the E. coli form using a standard re-induction regimen (Vincristine, Dexamethasone, Doxorubicin) for patients with relapsed ALL who have developed an allergy to the E. coli formulation. This study will administer the drug intravenously instead of the usual intramuscular route. The dose of Erwinia will be escalated in the absence of dose limiting toxicity. Patients must have first or second relapse ALL with a history of prior systemic reaction to E. coli asparaginase.
