Filter by:This is a pilot clinical trial of dronabinol to treat disabling attacks of nausea and vomiting in patients with familial dysautonomia (FD, also known as Riley Day syndrome or hereditary sensory and autonomic neuropathy type III). FD is a rare autosomal recessive disease in which the growth and development of selective nerves is impaired. Patients with FD suffer recurrent uncontrollable nausea and vomiting crises accompanied by skin flushing, tachycardia and arterial hypertension. Current treatments of nausea are ineffective or have intolerable side sides. Our long-term goal is to treat nausea effectively and without side effects, a therapeutic intervention that would markedly improve the quality of life of patients with FD.
The primary study hypotheses are that, without increasing doses of breakthrough medications or device intolerance, the Nometex™ device worn for 5-days beginning with the day of chemotherapy administration in women with ovarian or advanced endometrial or cervical cancer will, as an adjunct to standard-of-care anti-emetics, reduce vomiting episodes, and reduce the severity of nausea. The secondary hypotheses are that the Nometex™ device reduces acute (Day 1) emetic episodes, day 1 and days 2-5 severity of nausea, and delayed (days 2-5) emetic episodes without increasing doses of breakthrough medications or device intolerance.
This will be a blinded study to compare the absorption of topical haloperidol with placebo
The purpose of this study is to determine the dosing strategy for adolescents aged 2 to 5 years.
The purpose of this study is to determine the dosing strategy for adolescents aged 6 to 12 years.
This randomized pilot clinical trial studies giving acupuncture in reducing nausea and vomiting in patients undergoing chemotherapy. Pressing and stimulating nerves at an acupuncture point on the inside of the wrist may help control nausea and vomiting during chemotherapy.
Postoperative nausea and vomiting after outpatient surgery are significant sources of patient dissatisfaction. The prevention of postoperative nausea and vomiting (PONV) should be equally as important as prevention of pain because both are large sources of patient dissatisfaction and can necessitate admission after routine outpatient procedures. None of the currently available pharmacological interventions are able to totally abolish PONV. The use of electroacustimulation is a useful adjunct in prevention of PONV, but has yet to be studied when the patient takes the device home with them after leaving an outpatient facility.
Every year, more than 5 million patients in the US experience postoperative nausea and/or vomiting (PONV) and in the ambulatory setting post-discharge nausea and/or vomiting (PDNV) is the most common cause for unanticipated hospital re-admissions. Similarly, millions of patients suffer from chemotherapy induced nausea and/or vomiting (CINV), and one out of five patients discontinues chemotherapy for this reason. Thus, the control of nausea and vomiting remains a major health concern for the investigators society. The investigatorsoverall goal is to further the understanding of nausea and vomiting and optimize antiemetic selection in order to facilitate individualized patient care. Unfortunately, current antiemetics reduce the incidence of nausea by only about one third. As a result, antiemetics are often combined, exposing patients to adverse events and drug interactions without evidence for the most effective combination. Moreover, it remains unclear why such a large amount of inter-individual variability exists in antiemetic responsiveness. 5HT3, NK1, and GABA receptors are targets for some of the most commonly prescribed anti-emetics. Furthermore, these receptors have many known genetic polymorphisms, including several linked to incidence of nausea and vomiting. Thus pharmacogenomic variation may in part explain interindividual differences in treatment responses and will be tested in this proposal. Leveraging the established infrastructure of the UCSF Clinical and Translational Science Institute, and the support of 6 patient recruitment sites, the investigators will enroll 1280 high risk patients to three oral interventions with distinct mechanisms of action for nausea and vomiting. Investigating nausea and vomiting in ambulatory surgical patients is an excellent model for this trial owing to a high incidence, short observational period, and the ability to standardize and control potentially confounding variables. In this proposal, 100% of patients will receive a single intraoperative dose of 4 mg ondansetron, which is similar to the 80% of patients who receive prophylaxis in common practice. Using a factorial design, these patients will be randomized to receive one out of eight possible combinations of the three interventions (ondansetron, aprepitant, lorazepam) versus placebo (ond+aprep+lora, ond+aprep, ond+lora, aprep+lora, ond, aprep, lora, or placebo). Thus, in this proposal 87.5% (7 out of 8 patients) will have antiemetic coverage for the postdischarge period, which is considerably higher than in common practice, where only 4% of patients have antiemetic coverage after discharge. The primary endpoint will be the prevention of nausea and vomiting within 48 hours after ambulatory surgery. The advantage of the factorial trial design is its high efficiency to systematically investigate multiple interventions while allowing us to test for potential interactions. It is also an ideal format for the simultaneous assessment of pharmacogenomic interactions of antiemetics in this proposal. To this end, the investigators will collect DNA samples and take advantage of the unique opportunity to investigate the effects of variation in candidate receptor genes in the context of the three treatment interventions for PDNV. This approach may in part explain inter-individual differences in drug efficacy and allow for future screening of at-risk patients. Specifically, the investigators will be assessing single nucleotide polymorphisms (SNPs) and copy number variants (CNVs) of targeted receptors for the antiemetics tested. Aim 1: To determine efficacy of three interventions for the prevention of PDNV. Hypothesis 1.1: Each intervention reduces the incidence of PDNV. Hypothesis 1.2: Efficacy of all interventions is independent so that efficacy of a combination can be derived from the efficacy of the individual interventions. Aim 2: To determine if drug response for anti-emetics is dependent upon genetic variance. Hypothesis 2: Efficacy of ondansetron, aprepitant and lorazepam to reduce PDNV differs with 5HT3, NK1, and GABA receptor gene variation, respectively.
The investigators hypothesize that in adult patients with diabetic gastroparesis with Type 1 diabetes (HbA1c ≤ 10.5%), daily tadalafil use will significantly improve gastric emptying compared to baseline as measured by gastric emptying time.
This study is looking at whether the addition of Aprepitant (Emend), an antiemetic, will provide added efficacy if added to 2 drugs that are already used as a standard of care for post-operative nausea and vomiting and post-discharge nausea and vomiting.
