简要总结
Study Objectives Primary: To determine MTD and dose limiting toxicities (DLTs) of IOP magnetic resonance imaging (MRI) contrast agent in healthy subjects.
Secondary:
- To characterize the pharmacokinetic profiles of IOP MRI contrast agent in healthy subjects.
- To evaluate safety/tolerability profiles of IOP MRI contrast agent in healthy subjects.
- To explore efficacy profiles of IOP MRI contrast agent for liver organ in healthy subjects.
详细描述
Iron Oxide Nano Particle m-PEG-silane (IOP) Injection belongs to Superparamagnetic iron oxide (SPIO) can shorten the T2 relaxation time very effectively and reduces signal intensity in normal tissues. The mechanism of action increases after the particles have been phagocytosed by cells of the RES. Tissues with decreased RES function (e.g., metastases, primary liver cancer, cysts and various benign tumors, adenomas, and hyperplasia) retain their native signal intensity. In this study, investigators will characterize the PK profile, iron metabolism and preliminary efficacy of IOP Injection.

- •Alkaline phosphatase, ALT,AST, and total bilirubin.
- •Serum iron, total iron-binding capacity, serum ferritin,percent transferrin saturation (TSAT), and transferrin.
- •Human immunodeficiency virus (HIV), Hepatitis B surface antigen (HBsAg), Antibody HBsAg (anti-HBs),and antibodies against HCV (anti-HCV).
- •Subject shows normal complete blood count (CBC) test results (within normal range or considered clinically normal by the clinical investigator) at screening including items as listed below:
- •Red blood cell (RBC) count and reticulocyte count.
- •White blood cell (WBC) count with differential.
- •Hemoglobin and hematocrit.
- •Platelet count.
- •Subject shows normal urinalysis test results (within normal range or considered clinically normal by the clinical investigator) at screening including items as listed below:
- •pH, color, appearance, and gravity
- •Erythrocyte, leukocyte, glucose, protein, ketones, and nitrite
- •Drug and alcohol abuse screening test including morphine, 3,4 methylenedioxymethamphetamine(MDMA), 3,4-methylenedioxyamphetamine (MDA),ketamine, codeine and alcohol.
- •Subject shows normal bleeding time test results (within normal range or considered clinically normal by the clinical investigator) at screening including prothrombin (PT) and activated partial thromboplastin time (APTT).
- •Male subjects must take reliable contraceptive method(s) during and after the study for a period of 14 days.
- •No screening of drug or alcohol abuse within one year prior to study enrollment.
- •Subjects are willing to comply with the protocol and sign informed consent form.
排除标准
- •Subjects have serious allergic history or known allergy to similar ingredients of the study contrast agent (i.e.,Gd-based and SPIO particles contrast agents).
- •Subjects have been diagnosed of Hepatitis B or C, venereal disease laboratory screens or have been determined of positive result of human immunodeficiency virus test.
- •Imaging and/or functional abnormalities of liver and/or spleen. That is,
- •Subjects have been diagnosed of abnormal liver function and appearances through medical histories, clinical laboratory tests, and imaging test including mild fatty liver, iron deposition or any acute/chronic liver change.
- •Subjects have signs of splenomegaly, enlargement of the spleen, or clinical laboratory tests showing signs of spleen functional abnormalities.
- •Subjects have been performed with any examinations with contrast agents applied within 28 days before study.
- •Subjects have alcohol or caffeine consumption within 48 hours prior to the administration of study contrast agent.
- •Subjects are unable to undergo an MRI scan.
- •Subjects have electronically, magnetically and mechanically activated implanted devices, including but not limited to automatic cardioverter defibrillators, cardiac pacemakers,insulin pumps, metallic splinters in the eye, ferromagnetic haemostatic clips in central nervous systems or vascular vessels.
- •Subjects have participated in other investigational trials within 28 days prior to study enrollment.
- •Subjects with active systemic infections, active and clinically significant cardiac diseases, active gastrointestinal ulcers, or medical conditions that may significantly affect action,adequate absorption and elimination of investigational contrast agent.
- •Subjects have taken any food 6 hours prior to administration.
- •Subject with conditions judged by the investigator as unsuitable for the study.

结局指标
主要结局
Dose limiting toxicities (DLTs) of IOP
时间窗: Up to 14 days post-IOP injection
DLT is defined as any grade 2 or above toxicity by NCI-CTCAE version 4.03, as determined by the investigator and sponsor, to be at least possibly related in causality to the administered investigational product IOP
Maximum tolerated dose (MTD) of IOP
时间窗: Up to 14 days post-IOP injection
MTD is defined as the prior dose level below the dose level at which 2/6 subjects suffer dose limiting toxicities
