Description

3-iodobenzylguanidine (MIBG) is a synthetic guanethidine analog that has been studied for its use in treating neuroblastoma, a type of cancer that affects the nervous system. MIBG is an effective radiopharmaceutical agent, meaning it concentrates in tissues and can be visualized with imaging. This is possible due to its ability to target the norepinephrine transporter (NET) in neuroblastoma cells, which results in the compound being accumulated within the tumor. This characteristic allows for the use of MIBG in both diagnostic imaging and therapeutic applications. When labeled with radioactive iodine-131 (I-131), MIBG serves as a therapeutic agent. The therapeutic effects are due to the localized radiation emitted by the I-131 within the tumor cells. In terms of synthesis, MIBG is typically synthesized through a series of reactions involving the coupling of 3-iodobenzyl bromide with guanidine. MIBG is actively studied for its potential in cancer therapy, particularly neuroblastoma, and for its applications in nuclear medicine imaging. The accumulation of MIBG in neuroblastoma cells, its ability to be labeled with radioactive isotopes, and its relatively low toxicity make it a promising tool for both diagnosis and treatment. However, further research is still needed to better understand its mechanisms of action and to optimize its use in clinical settings.'

3-Iodobenzylguanidine: A guanidine analog with specific affinity for tissues of the sympathetic nervous system and related tumors. The radiolabeled forms are used as antineoplastic agents and radioactive imaging agents. (Merck Index, 12th ed) MIBG serves as a neuron-blocking agent which has a strong affinity for, and retention in, the adrenal medulla and also inhibits ADP-ribosyltransferase.

Relationship Between the Occurrence of Adverse Cardiac Event and 123I-mIBG Uptake on Planar Scintigraphy Categorized as High or Low Heart to Mediastinum (H/M) Ratio

H/M ratio for 123I-mIBG uptake at 3 hours 50 minutes post administration was calculated by dividing the counts/pixel in the total myocardium region of interest (ROI) by the counts/pixel in the 7x7 pixel mediastinal ROI. Assessments were done by 3 independent readers. H/M ratios were categorized as 'Low' and 'High' based on being <1.6 or ≥1.6 respectively. The efficacy of 123I-mIBG was based on the prognostic value of the imaging data collected relative to time to adverse cardiac events. (NCT00126425)

MTD of Ultratrace Iobenguane I 131

Although no primary efficacy endpoint was defined for this study, the MTD of Ultratrace iobenguane I 131 in patients with malignant pheochromocytoma/paraganglioma (a safety rather than an efficacy parameter) is the primary objective. (NCT00458952)

Dose Limiting Toxicities

Dose limiting toxicities include treatment emergent adverse events (TEAEs) that were possibly, probably, or definitely related to Ultratrace™ Iobenguane I 131. (NCT00659984)

Maximum Tolerated Dose

The maximum tolerated dose (MTD) was defined as the dose immediately below the level at which dose escalation would be stopped due to dose limiting toxicities (DLTs). Once the MTD was reached, an additional 3 patients were to be treated at that dose level, for a total of 6 patients at that planned dose level. DLTs were defined as any of the events that are possibly, probably or definitely attributable to UltratraceTM iobenguane I 131. The MTD was supposed to be the highest dose tested at which fewer than 1/3 of pts experience a DLT when 6 patients have been treated at the MTD but the dosimetry results indicated that the maximal dosage allowed to normal organs would be exceeded if the highest planned dose (21.0 mCi/kg) was administered, so the highest dose administered in the study was 18.6 mCi/kg .

Overall Objective Tumor Response Post Therapeutic Treatment

The International Neuroblastoma Response Criteria (INRC) were utilized as a basis for the overall response criteria, which incorporated responses in MIBG positive lesions,bone marrow disease, and CT/MRI lesions that met NANT-modified RECIST criteria. Efficacy success was defined as the proportion of pts who were successful overall [i.e., achieving a Complete Response (CR), Very Good Partial Response (VGPR), or Partial Response (PR)] determined by independent reviewers. CR = Disappearance of all target lesions, homovanillic acid/ vanillylmandelic acid (HVA/VMA) normal (NL); VGPR = > 90% decr of disease for CT/MRI target lesions, all pre-existing bone lesions with CR by MIBG; MIBG scan can be SD/CR in soft tissue lesions. CR in bone marrow, no new tumor sites, and NL HVA/VMA.; PR = At least 30% decr in disease measurement for CT/MRI target lesions. Bone marrow with CR, MIBG with either PR/CR in bone lesions, MIBG may be SD /CR in soft tissue lesions, and HVA/VMA may still be elevated. (NCT00659984)

PedsQLTM consists of 4 scales (physical, emotional, social, school functioning) which are then averaged into an overall summary score (scale: 0-100 with 0 representing the worst possible Quality of Life overall summary score and 100 representing the best possible Quality of Life overall summary score). The mean difference between the post treatment overall summary score and the baseline overall summary score is reported. (NCT00659984)

Tumor Response in CT/MRI Lesions Post Therapeutic Treatment

Measurable disease was defined for a conventional CT scan by the presence of at least one lesion that could be accurately measured in at least one dimension with the longest diameter at least 20 mm by Independent Review. Efficacy success was defined as a patient achieving a Complete Response (CR)=disappearance of all target and non-target CT/MRI lesions; or, Very Good Partial Response (VGPR)=greater than 90% decrease of the disease measurement for CT/MRI lesions, taking as reference the disease measurement done to confirm measurement disease at study entry. Non-target CT/MRI lesions stable to smaller in size; or, Partial Response (PR)=at least 30% decrease in the disease measurement for CT/MRI lesions, taking as reference the disease measurement done to confirm measurable disease at study entry. Non-target CT/MRI lesions stable to smaller in size. (NCT00659984)

Dosimetric Estimation of Radiation Absorbed Doses to Measurable Lesions

The dosimetric endpoint was to estimate radiation absorbed doses to measurable lesions and to a standard set of normal organs following an imaging dose of 0.1 mCi/kg Ultratrace™ Iobenguane I 131. Biodistribution was assessed by determination of total body residence (TBR) time and by visual examination of whole body camera images. 3 timepoints were used, the 1st image was taken within 1hr after the imaging dose, the 2nd image was taken at ~24hr after imaging dose, the 3rd image was taken 2-5d after imaging dose. Whole body radiation absorbed dose estimates & kidney, liver, and lung were calculated using the Medical Internal Radiation Dose (MIRD) schema.TBR time is derived from time integration of curve-fitted injected activity across all 3 timepoints when the isotope is emitting radiation.Three points are sampled to estimate a singular value for each organ and tissue according to the commonly used methods of the Society of Nuclear Medicine and Molecular Imaging Committee on MIRD.

Changes From Baseline in Overall Quality of Life (QoL) - Best Response Within 12 Months After First Therapeutic Dose of AZEDRA®.

The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) C30 v.3 was used to evaluate QoL. This questionnaire was comprised of 30 questions, two of which pertain to a patient's Global Health Status and QoL. The two questions used a 7-point Likert scale of 1 (very poor) to 7 (excellent), in which the scores were averaged and linearly transformed to a 0-100 scale with higher scores indicating better health status and QoL. The questionnaire was administered at baseline and through 12 months after the first therapeutic dose of AZEDRA®. The results of QoL and changes from baseline were summarized by visit and the best response within 12 months after first therapeutic dose of AZEDRA® was reported. The outcome represents the mean change from baseline in overall QoL based on the best response reported within 12 months after first therapeutic dose of AZEDRA®. (NCT00874614)

Comparison of the Number of Lesions Detected as Positive by [123I]mIBG Planar Scintigraphy Which Are Also Considered Positive With [124I]mIBG PET/CT.

Analysis of [124I]mIBG PET/CT and [123I]mIBG planar scintigraphy was performed retrospectively by four specialist observers. The analysis was performed and observers were blinded to each others scores. The observers subsequently reviewed the lesions identified and, where there was a difference in their separate scores, they returned to the images in order to reach an agreed consensus score. The number of lesions identified as positive by this consensus scoring (all lesions with a SIOPEN score of 4 or 5) were used to meet the primary objective. (NCT02043899)
