Trial Outcomes & Findings for Study of Ferumoxytol Enhanced MRI for Detecting Lymph Node Metastases in Prostate, Bladder, and Kidney Cancers (NCT NCT02141490)

NCT ID: NCT02141490

Last Updated: 2019-09-06

Results Overview

Visible nodes were quantified with manually contoured regions of interest on axial T2\*W MRI to obtain the mean signal intensity (SInode). The SI of the visible lymph node was normalized using the mean SI of the adjacent muscle tissue on the same slice (SImuscle). The following equation was used to obtain the normalized SI from the lymph node (SInormal): SInormal=SInode/SImuscle. The calculation formula was 100% \* ((SInormal(24hrs)- SInormal(baseline))/ SInormal(baseline)).This image processing method was performed at baseline, 24-hours post-injection MRI studies to define the SI change differences between benign and malignant lymph nodes from baseline to 24 hours post injection.

SECONDARY outcome

Timeframe: pre-infusion, 24 hours and 48 hours

Population: The analysis for this outcome measure was not done because most of the patients had deeply located lymph nodes and logistically ultrasonography analysis was not possible.

Patients will undergo ultrasound examination of imageable lymph nodes at pre-infusion, 24 hours and 48 hours. The signal changes at post-infusion ultrasound will be visually evaluated to determine if the uptake of ferumoxytol alters sonographic features.

SECONDARY outcome

Timeframe: Adverse events were assessed from the date treatment consent signed to date off study, approximately 3 years, 3 months, and 11 days on the Prostate Cancer Arm/Group; 2 years, 5 months, and 19 days on the Bladder Cancer Arm/Group, and 1 year, 6 months, and

Population: Results are available for 39/43 subjects because 4 were screen failures.

Here is the count of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria in 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.
