This study is to determine the maximum tolerated dose and the recommended 188Re-SSS Lipiodol activity for hepatic intra-arterial injection in patients with hepato-cellular carcinoma. The new radioactive isotope 188Rhenium associated with Lipiodol is expected to reduce the radioprotection constraints and hence the duration of the hospitalisation in a protected room from 8 to 1 day.

ObjectiveHepatocellular carcinoma (HCC) with portal vein thrombosis (PVT) have limited therapeutic options, Re-188 lipiodol transarterial therapy being one of them. We aimed to assess the safety and efficacy of Re-188 lipiodol exclusively in HCC with PVT as well as to compare two chelating agents for the synthesis of Re-188 lipiodol: novel bis-(diethyldithiocarbamato) nitrido (N-DEDC) with existing acetylated 4-hexadecyl 1-2,9,9-tetramethyl-4,7-diaza-1,10-decanethiol [(A)HDD].MethodsPatients with radiological diagnosis of HCC with PVT having Eastern Cooperative Oncology Group (ECOG) performance status ≤2 and Child Pugh score (PS) A or B were recruited. Patients received an empirical dose of transarterial Re-188 lipiodol, labelled with (A)HDD or N-DEDC. Radiological response on MRI (modified response evaluation criteria in solid tumors), biochemical response with serum alpha fetoprotein and clinical response with ECOG PS was assessed at three months and survival was estimated at the end of the study.ResultsFifteen therapies were performed in 14 patients with a median age of 62 years (range: 41–70 years). Eight therapies were with Re-188 (A)HDD lipiodol and seven with Re-188 N-DEDC lipiodol. Overall mean injected dose was 2.6 ± 0.37 GBq. Radiological objective response rate was 31% and disease control rate was 85%. Mean overall survival was 14.21 months and mean progression free survival was 10.23 months. Percentage survival assessed at 3, 6 and 9 months was 93%, 64% and 57%, respectively. Safety parameters, response and survival outcome were comparable for (A)HDD and N-DEDC groups.ConclusionTransarterial Re-188 lipiodol in HCC with PVT is safe and effective in disease control as well as improving survival outcome. Additionally, cost-effective and high-yielding novel agent N-DEDC appears to be a comparable alternative to (A)HDD for the same.

¹⁸⁸Re-SSS Lipiodol Radioembolization in HCC Patients: Results of a Phase 1 Trial (Lip-Re-01 Study).

BACKGROUNDDespite the wide development of ⁹⁰Y-loaded microspheres, ¹⁸⁸Re-labeled lipiodol is still being used for radioembolization of hepatocellular carcinoma (HCC). However, the use of this latter compound is limited by in vivo instability. This study sought to evaluate the safety, bio-distribution, and response to ¹⁸⁸Re-SSS lipiodol, a new and more stable compound.METHODLip-Re-01 was an activity-escalation Phase 1 study involving HCC patients progressing after sorafenib. The primary endpoint was safety based on Common Terminology Criteria for Adverse Events (AEs) of Grade ≥3 within 2 months. Secondary endpoints included bio-distribution assessed by scintigraphy quantification from 1 to 72 h, tumor to non-tumor uptake ratio (T/NT), as well as blood, urine and feces collection over 72 h, dosimetry, and response evaluation (mRECIST).RESULTSOverall, 14 heavily pre-treated HCC patients were treated using a whole liver approach. The mean injected activity was 1.5 ± 0.4 GBq for activity Level 1 (n = 6), 3.6 ± 0.3 GBq for Level 2 (n = 6), and 5.0 ± 0.4 GBq for Level 3 (n = 2). Safety was acceptable with only 1/6 of Level 1 and 1/6 of Level 2 patients experiencing limiting toxicity (one liver failure; one lung disease). The study was prematurely discontinued unrelated to clinical outcomes. Uptake occurred in the tumor, liver, and lungs, and only sometimes in the bladder. The T/NT ratio was high with a mean of 24.9 ± 23.4. Cumulative urinary elimination and fecal eliminations at 72 h were very low, 4.8 ± 3.2% and 0.7 ± 0.8%, respectively. Partial response occurred in 21% of patients (0% in the first activity level; 37.5% in the others).CONCLUSIONThe high in vivo stability of ¹⁸⁸Re-SSS lipiodol was confirmed, resulting in encouraging responses for a Phase 1 study. As the 3.6 GBq activity proved to be safe, it will be used in a future Phase 2 study.

Preparation of Rhenium-188-Lipiodol Using Freeze-Dried Kits for Transarterial Radioembolization: An Overview and Experience in a Hospital Radiopharmacy

Background: Rhenium-188(¹⁸⁸Re)-lipiodol is a clinically effective, economically viable radiopharmaceutical for Selective Internal Radiation Therapy of liver cancer. Present study evaluates the performance of three freeze-dried kits with respect to the radiochemistry, quality control, and overall "ease of preparation" aspects in a hospital radiopharmacy. Materials and Methods: Freeze-dried kits of acetylated 4-hexadecyl-4,7-diaza-1,10-decanedithiol (AHDD), super six sulfur (SSS), and diethyl dithiocarbamate (DEDC), obtained commercially or received as gift, were used for the preparation of ¹⁸⁸Re-lipiodol using freshly eluted ¹⁸⁸Re-sodium perrhenate from commercial Tungsten-188/¹⁸⁸Re generator following recommended procedures. Results: The overall yield of ¹⁸⁸Re-lipiodol prepared using AHDD Kit, SSS Kit, and DEDC Kit was 74.82% ± 3.3%, 87.55% ± 4.8%, and 76.38% ± 4.6%, respectively. Observed radiochemical purity (RCP) of ¹⁸⁸Re-lipiodol prepared using these kits was 88.65% ± 2.8%, 92.92% ± 3.0%, and 91.38% ± 3.0%, respectively. Using a modified version of the DEDC Kits, overall yield of 87.17% ± 2.7% and RCP of 95.43% ± 2.3% could be achieved. Conclusions: While all three freeze-dried kits can be used for the preparation of ¹⁸⁸Re-lipiodol in >70% overall yield, the modified version of DEDC Kits has some advantages in terms of preparation time and volume of Rhenium-188 activity that can be added to the kit vial. The latter feature of the DEDC Kit is particularly useful for patient dose preparation with ¹⁸⁸Re activity of low radioactive concentration.
