fluorouracil and Melena

fluorouracil has been researched along with Melena in 3 studies

Fluorouracil: A pyrimidine analog that is an antineoplastic antimetabolite. It interferes with DNA synthesis by blocking the THYMIDYLATE SYNTHETASE conversion of deoxyuridylic acid to thymidylic acid.
5-fluorouracil : A nucleobase analogue that is uracil in which the hydrogen at position 5 is replaced by fluorine. It is an antineoplastic agent which acts as an antimetabolite - following conversion to the active deoxynucleotide, it inhibits DNA synthesis (by blocking the conversion of deoxyuridylic acid to thymidylic acid by the cellular enzyme thymidylate synthetase) and so slows tumour growth.

Melena: The black, tarry, foul-smelling FECES that contain degraded blood.

Trial Overview

Trial Outcomes

Number of Participants With Serious and Non-Serious Adverse Events

Here is the number of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. (NCT01479348)
Timeframe: Date treatment consent signed to date off study, approximately 20 months and 12 days.

Frequency and Severity of Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE) v4.0

[F-18]-5-fluoro-2'-deoxycytidine (FdCyd) was administered intravenously with administration of tetrahydrouridine (THU) and the frequency and severity of adverse events was observed. A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. Grade 0 is normal, Grade 1 is mild, Grade 2 is moderate, Grade 3 is severe or medically significant but not immediately life-threatening, Grade 4 is life-threatening consequences, and Grade 5 is death related to adverse event. (NCT01479348)
Timeframe: Within 5 days after interventions

Radiation Dosimetry Estimates of 5-fluoro-2'-Deoxycytidine (FdCyd) in Humans

Radiation dosimetry was determined based on the first patients. This involved making region of interest measurements on the scan for each major organ and measuring the uptake. Using standard dosimetry software this is converted into mSv/MBq, a standard measure of dosimetry. The software is known as Organ Level INternal Dose Assessment/EXponential Modeling (OLINDA) and is commonly used to generate this kind of data. (NCT01479348)
Timeframe: 1 year

Tumor to Background Ratios (TBRs) of Target Lesions at 4 Time Points After Injection

Participants were scanned by positron emission tomography (PET) and lesions were measured at 4 time points after injection. (NCT01479348)
Timeframe: 9 minutes, 32 minutes, 56 minutes and 2 hours after injection
