OTC	NCT03145012 ↗	Histamine Receptor 2 Antagonists as Enhancers of Anti-Tumour Immunity	Unknown status	Dalhousie University	Phase 4	2018-05-01	The immune response against tumors can be highly effective in preventing tumor development, growth and metastasis under certain circumstances. However, tumor associated immune suppression can profoundly limit the impact of natural tumor immunity and also reduce the effectiveness of tumor immunotherapy strategies. A major component of tumor associated immune suppression is mediated by myeloid cells, especially the monocytic subset of myeloid derived suppressor cells (MDSC). In recent studies that were conducted through a CCSRI Innovation grant, the investigators discovered that oral treatment of mice with the commonly used histamine receptor 2 (H2) antagonists ranitidine or famotidine inhibits both primary breast tumor development and metastasis, in three distinct mouse tumor models and reduces the numbers of monocytic MDSC. These findings have enormous potential to aid in effective cancer immunotherapy and may have immediate implications for cancer patients. The objective of this investigation is to determine whether treatment with the H2 receptor antagonist ranitidine alters immune suppression, through modulation of immune cell populations. The investigators will examine peripheral blood monocyte, neutrophil and NK cell numbers, subsets and activation status from healthy volunteers treated for 6 weeks with daily oral ranitidine. Ranitidine is widely available and used over the counter in Canada. These drugs are widely recognized as safe, well tolerated and have very few side effects. It has been suggested that among the general population, over 10% of those over the age of 65 take such medications on a regular basis for relief against gastrointestinal discomfort. The outcome of pre-clinical studies in mice warrant further investigation into transferability to humans. If the outcome of the current proposal proves to be viable, then these drugs could provide a safe method to reduce tumor associated immunosuppression with broad implications, both for current cancer patients and for those at high risk of developing cancer. Further to this, the outcome of our proposal may provide a new strategy for improving the effectiveness of T-cell mediated immunotherapy.

OTC	NCT04397445 ↗	Clinical Study to Investigate the Urinary Excretion of N-nitrosodimethylamine (NDMA) After Ranitidine Administration	Completed	Spaulding Clinical Research LLC	Phase 1	2020-06-08	Ranitidine is an over-the-counter and prescription drug, which decreases the amount of acid secreted by the stomach. Some ranitidine medicines contain an impurity called N-nitrosodimethylamine (NDMA) at low levels. NDMA is classified as a probable human carcinogen (a substance that could cause cancer) based on results from laboratory tests. NDMA is a known environmental contaminant and found in water and foods, including meats, dairy products, and vegetables. The US Food and Drug Administration (FDA) has found levels of NDMA in some ranitidine products similar to the levels you would expect to be exposed to if you ate common foods like grilled or smoked meats. The ranitidine that will be used in this study has been tested twice (months apart) and shown to have stable NDMA levels well below the acceptable daily limit. Of note, the risk of NDMA with ranitidine is only relevant with prolonged chronic administration as at the acceptable limit, there is approximately a 1 in 100,000 chance of cancer after 70 years of exposure to that level. FDA has also conducted tests that simulate the potential formation of NDMA from ranitidine after it has been exposed to acid in the stomach with a normal diet. Results of these tests indicate that NDMA is not formed in typical stomach conditions. Similarly, if ranitidine is exposed to a simulated small intestinal fluid, NDMA is not formed. Other laboratory experiments suggest a combination of nitrites, such as found in processed meats, and an acidic environment may increase NDMA formation, however the levels of nitrites tested were very high. Separately, a previous study in 10 healthy volunteers showed that volunteers who received ranitidine had an increase in urinary NDMA excreted over 24 h. The level of increase was greater than would be expected from laboratory testing. This clinical study is being performed to determine if and how much NDMA is produced from ranitidine in the human body and whether nitrite-containing foods may increase formation of NDMA. The study will use a prescription dose of ranitidine (300 mg) to test whether there is increased urinary NDMA excretion levels over 24-hours after ranitidine administration in comparison to placebo when participants are administered low nitrite/NDMA meals and when subjects are administered high nitrite/NDMA meals. On 4 different days, each participant will receive ranitidine or placebo with high nitrite/NDMA meals and ranitidine or placebo with low nitrite/NDMA meals.

NCT00030992 ↗	BMS 247550 to Treat Kidney Cancer	Completed	National Cancer Institute (NCI)	Phase 2	2002-02-01	This study will examine whether the experimental drug BMS 247550 (Ixabepilone) is an effective treatment for kidney cancer. BMS 247550 belongs to a class of drugs called epothilones that interfere with the ability of cancer cells to divide. In the way they kill cells, they are very similar to a class of compounds known as the taxanes, which include the drug Taxol. Other characteristics of the epothilones, however, enable them to work in cells that are resistant to Taxol. Patients 18 years of age or older with kidney cancer that has not spread to the central nervous system (unless the brain tumor has remained stable for at least six months after surgical or radiation treatment) may be eligible for this study. Pregnant or nursing women may not participate. Candidates are screened with various tests that may include blood and urine tests, electrocardiogram (EKG), and chest x-ray. Computerized tomography (CT) scans or X-rays, and possibly nuclear medicine studies may be done to determine the extent of disease. Participants receive BMS 247550 by a 1-hour infusion into a vein for 5 consecutive days (days 1, 2, 3, 4 and 5) of each 21-day treatment cycle. Patients must stay in the National Institutes of Health (NIH) area near Bethesda, Maryland, for 7 to 8 days during the first treatment cycle and for the 5 days of treatment in subsequent cycles. The total number of cycles will vary among patients, depending on their individual clinical situation. The drug dose may be increased gradually in subsequent cycles in patients who can tolerate such increases. In addition, participants undergo the following tests and procedures: - Periodic physical examinations and frequent blood tests - X-ray and other imaging studies to determine if the tumor is responding to the treatment. - Tumor biopsies to confirm the diagnosis or spread of tumor and to examine the reaction of certain proteins in cancer cells to BMS 247550. Two biopsies will be done. For this procedure, a small piece of tumor tissue is withdrawn through a needle under local anesthetic. Treatment will be stopped in patients whose tumor grows while receiving BMS 247550. Patients whose tumor disappears completely will be followed at NIH periodically for examinations and tests. Patients whose disease does not completely resolve or whose disease recurs may be advised of other appropriate research protocols at NIH or, if none are available, will be returned to the care of their local doctor.
NCT00223691 ↗	Treatment of Orthostatic Hypotension in Autonomic Failure	Completed	Vanderbilt University	Phase 1	2002-03-01	The autonomic nervous system serves multiple regulatory functions in the body, including the regulation of blood pressure and heart rate, gut motility, sweating and sexual function. There are several diseases characterized by abnormal function of the autonomic nervous system. Medications can also alter autonomic function. Impairment of the autonomic nervous system by diseases or drugs may lead to several symptoms, including blood pressure problems (e.g., high blood pressure lying down and low blood pressure on standing), sweating abnormalities, constipation or diarrhea and sexual dysfunction. Because treatment options for these patients are limited. We propose to study patients autonomic failure and low blood pressure upon standing and determine the cause of their disease by history and examination and their response to autonomic testing which have already been standardized in our laboratory. Based on their possible cause, we will tests different medications that may alleviate their symptoms.

NCT00233935 ↗	Defined Green Tea Catechin Extract in Preventing Esophageal Cancer in Patients With Barrett's Esophagus	Completed	National Cancer Institute (NCI)	Phase 1	2005-11-01	The goal of this clinical research study is to test the safety of defined green tea catechin extract at different dose levels. Researchers also want to find out what effects, good and bad, it may have on individual and their risk for esophagus cancer. Esophagus cancer is an increased risk associated with Barrett's esophagus. Chemoprevention is the use of certain drugs to keep cancer from forming, growing, or coming back. The use of defined green tea catechin extract may prevent esophageal cancer.
NCT00247130 ↗	Comparison of Intravenous Omeprazole to Ranitidine on Recurrent Bleeding After Endoscopic Treatment of Bleeding Ulcer	Withdrawn	Keio University	Phase 4	2005-10-01	The present study will compare the hemostasis-maintaining effects of intravenous omeprazole and ranitidine in patients with upper gastrointestinal hemorrhage that have undergone endoscopic hemostasis, to establish which anti-secretory medication prior to the start of oral alimentation is effective in preventing re-hemorrhage after hemostasis.
NCT00443963 ↗	Total Antioxidant Effects of Esomeprazole in Dyspeptic Patients Receiving Non-steroidal Anti-inflammatory Drugs	Withdrawn	AstraZeneca	Phase 4	2006-12-01	The principal investigator hypothesizes that participants receiving NSAID drugs with dyspeptic symptoms have increased production of gastric levels of free radicals. The primary objective of the study is to determine if Esomeprazole Magnesium increases gastric total antioxidant capacity and decreases gastric free radical production in humans. Participants (age 18 years and older) with no history of upper GI bleeding who are receiving non-steroidal anti-inflammatory drugs and then develop dyspepsia will be recruited from our primary care clinic in Washington, DC. All eligible participants will undergo biopsies of antrum and corpus. The participants will be randomized to receive either Zantac OTC or Nexium for 15 days. On day 15, all participants will undergo repeat upper endoscopy to obtain biopsies of antrum and corpus. Tissue samples will then be extracted to determine total antioxidant capacity and lipid peroxide levels (as an indirect marker of free radical production).
