Detailed Description

Tumor-induced osteomalacia (TIO), also known as oncogenic osteomalacia, is a rare paraneoplastic syndrome. The key to the cure of TIO is surgical resection of the culprit tumor. Over the last decade, 68Ga-labeled SSTR-based imaging has made a significant impact in detecting the culprit tumor of TIO 68Ga-DOTA-TATE is the most used SSTR PET tracer for the detection of TIO and it was recommended as first-line imaging method for localization of the causative tumor.

However, false positive, including fracture and/or inflammation, in 68Ga-DOTA-TATE PET/CT is a challenge in image interpretation, which may make the causative tumor indistinguishable in multiple suspicious lesions. There is no effective way to identify multiple suspicious lesions with intensive increased uptake on 68Ga-DOTA-TATE PET/CT.

68Ga-DOTA-JR11 is a SSTR2 specific antagonist used for PET tracer. However, the SSTR2 affinity of 68Ga-DOTA-JR11 is lower than 68Ga-DOTA-TATE, which means that the uptake of 68Ga-DOTA-JR11 by suspected lesions may be lower than that of 68Ga-DOTA-TATE. The purpose of this prospective study is to compare the sensitivity of 68Ga-DOTA-JR11 and 68Ga-DOTA-TATE PET/CT for detecting the responsible tumor of TIO and investigate if 68Ga-DOTA-JR11 PET/CT can identify the culprit tumor of TIO in multiple suspicious lesions.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
