AFP-DIAM Score to Predict Survival in Patients with Hepatocellular Carcinoma Before TACE: A French Multicenter Study.

BACKGROUND: Transarterial chemoembolization (TACE) is recommended as a palliative treatment for patients of the B stage of the Barcelona Clinic Liver Cancer (BCLC) classification. AIMS: To identify clinical, biological, and radiological predictors of survival in patients undergoing TACE and develop a pre-therapeutic prognostic score. METHODS: 191 adult cirrhotic patients treated for HCC with TACE at the University Hospital (UH) of Clermont-Ferrand (France) from 2007-2017 were retrospectively included. We investigated the impact of baseline liver function, patient characteristics, and tumor burden on overall survival and developed a prognostic score. RESULTS: Patients had a median age of 66 years and 126 patients were Child A. The AFP-DIAM score distinguishes two groups with a significant difference in survival time (median OS 28.3 months in patients with a score = 0 versus 17.7 months in patients with a score > 0). AFP-DIAM was validated on an external cohort, is well calibrated, and has the best discrimination capacity (C-index) as compared to NIACE, HAP, STATE, and SIX TO TWELVE. AFP-DIAM and SIX TO TWELVE are the more easy-to-use scores. When AFP-DIAM and the SIX TO TWELVE scores were tested in the same statistical model, results confirmed a better AFP-DIAM performance. CONCLUSIONS: The AFP-DIAM is an easy-to-use score which allows to distinguish two groups with different prognosis before the first TACE session. Its use could provide further support to BCLC system to guide the therapeutic strategy of patients with HCC.

Oral anticancer medicine interventions: A cross-sectional study in French community pharmacies.

INTRODUCTION: The increasing number of oral anticancer medicines (OAMs) dispensed in community pharmacies and the associated challenges (misuse, management of side effects) give the community pharmacist (CP) a major role in the pharmacotherapeutic management of cancer patients. In France, as a response to these challenges, cancer outpatients can schedule a meeting with their CP to ensure the safe and effective use of OAMs. The objectives of this study were to evaluate the perspectives of these interventions regarding their implementation and the opinion of French CPs. METHODS: A declarative survey and semi-structured interviews were conducted with CPs that dispensed at least one OAM between January 2021 and March 2022. The study was conducted between April and August 2022. RESULTS: Eighty-five CPs completed the survey. Of these pharmacists, 21% (n = 18) had already performed OAM interventions and 91% (n = 61) wanted to implement them. Lack of time, knowledge and training were the main barriers to implementation. No correlations were identified between the characteristics of community pharmacies and the likelihood of implementing OAM interventions. CONCLUSIONS: Considering that CPs seem willing to implement them and the favourable context in France, this observational study highlights the potential of OAM interventions to improve the management of cancer patients. Though further studies are required to better evaluate the implementation and the potential effects of these interventions, OAM interventions could be relevant strategies in other healthcare systems to secure the management of cancer patients through the involvement of the CP.

Glycemic and lipid control in patients with diabetes at time of myocardial infarction.

OBJECTIVE: Cardiovascular risk is increased in patients with diabetes. Little is known about glycemic and lipid control in patients with diabetes. We aimed to assess glycemic and lipid controls in patients with diabetes at time of their myocardial infarction. METHOD: All known patients with type 2 diabetes consecutively admitted for a myocardial infarction in our coronary care unit between March 1st and December 31st, 2021 were included in this retrospective study. Glycemic and lipid control was assessed through individualized target of glycated haemoglobin (HbA1c) and low-density lipoprotein cholesterol (LDL-c), respectively. At admission, the comprehensive list of chronic medications was obtained through medication reconciliation. RESULTS: This study included 112 patients with a median age of 72 years. Most of patients had an individualized target of HbA1c and LDL-c of 7.0% (67%) and 0.55g/L (96%), respectively. The rate of uncontrolled patients for HbA1c and LDL-c and both was 46%, 90%, and 42% respectively. The rate of patients with non-optimal glucose- and lipid-lowering medications in uncontrolled patients was 63% and 87%, respectively. The rate of inappropriate glucose- and lipid-lowering medications was 73% and 91%, respectively. CONCLUSION: We highlighted the poor glycemic and lipid control in high-risk CV patients. There is an urgent need to develop multidisciplinary approaches to optimize CV risk factors control to reduce myocardial infarction and strokes.

Impact of G-CSF Prophylaxis on Chemotherapy Dose-Intensity, Link Between Dose-Intensity and Survival in Patients with Metastatic Pancreatic Adenocarcinoma.

BACKGROUND: In metastatic pancreatic adenocarcinoma, few data are available on the use of granulocyte-colony stimulating factor (G-CSF) prophylaxis and its impact on dose-intensity (DI), or the link between DI and progression-free survival (PFS). This study assessed the impact of G-CSF prophylaxis on the DI received by patients and the relationship between full DI and PFS according to chemotherapy regimens. PATIENTS AND METHODS: Patients from three first-line randomized phase II clinical trials were included in this retrospective cohort. G-CSF prophylaxis groups were identified and balanced according to baseline characteristics using a propensity score. Patients were classified into 2 treatment groups (FOLFIRINOX vs FOLFIRI/nab-paclitaxel (NAB)). DI was a binary variable (full/reduced). Adverse events were defined using NCI-CTCAE v4.0. RESULTS: Of the 498 patients, 154 (31%) were in "prophylaxis" group; 179 (36%) were treated by FOLFIRINOX and 319 (64%) by FOLFIRI/NAB. In FOLFIRINOX group, G-CSF prophylaxis was significantly associated with a higher rate of full DI (OR, 5.07; 95% CI, 1.52-16.90; P < .01) while in FOLFIRI/NAB group, it was significantly associated with a lower rate of full DI (OR, 0.23; 95% CI, 0.06-0.83; P = .03). Full DI was associated with a non-significant increase in PFS (FOLFIRINOX group: HR 0.83; 95% CI, 0.59-1.16; P = .27; FOLFIRI/NAB group: HR 0.84; 95% CI, 0.63-1.11; P = .22). CONCLUSION: Granulocyte-colony stimulating factor prophylaxis was associated with a higher rate of full DI with FOLFIRINOX. Full DI was associated with a non-significant increase in PFS. These results need to be confirmed prospectively.

Impact of first COVID-19 lockdown on paediatric and adult haemophilia patients treated in a French Haemophilia Comprehensive Care Centre.

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has created an unprecedented global health crisis. AIM: To investigate the impact of the 1st COVID-19 lockdown on haemophilia patients in terms of symptoms, management, medication adherence, mental health and lifestyle behaviours. METHODS: A prospective cross-sectional phone survey using a two-part questionnaire was conducted in haemophilia patients (adults and children) followed-up in a French Haemophilia Comprehensive Care Centre between May 5, 2020 and June 2, 2020 (CLEO CD study: NCT04390126). RESULTS: Among 284 haemophilia A or B patients with FVIII or FIX < 40% contacted for the study, 239 (84%) including 183 adults and 56 children participated to the survey. In 81% of children and 78% of adults, bleeding episodes remained unchanged or decreased. Medication adherence was 82.0% in adults and 98.2% in children. Non-adherence concerned haemostatic agents in six patients and analgesics in three. Overall, 67% of adults and 71% of children felt as good as before lockdown. In both adults and children, the three major changes in lifestyle behaviours were: increase in screen time (49% and 57%), decrease in physical activity (43% and 48%), and weight gain (32% and 27%), respectively. CONCLUSIONS: Encouraging results were observed in terms of haemophilia symptoms, medication adherence, and mental health. Conversely, a negative impact was observed on lifestyle behaviours in a cohort of French haemophilia patients during the 1st lockdown.

Self-management of immunomodulatory drug treatment in multiple myeloma patients.

OBJECTIVE: Immunomodulatory drugs (IMIDs: thalidomide, lenalidomide and pomalidomide) are widely used in patients with multiple myeloma (MM). The aim of our study was to validate a questionnaire to evaluate the self-capacity of MM patients to manage IMID treatment including side effects. METHODS: We used a method adapted from the recommendations of the European Organisation for Research and Treatment of Cancer (EORTC) to validate a French questionnaire for patients with MM treated with IMIDs. RESULTS: The face validity was evaluated in 15 patients and the construct validity in 56 patients. For discriminant validity, two groups were constituted by gender and depending on whether they had a previous IMID treatment. The median questionnaire score was 11.33/16 (IQR 9.75-12.08) with a minimum of 5.2 and a maximum of 14.75. For discriminant validity, a statistically significant difference was observed for patient capacity to contact healthcare professionals in specific situations and drug intake in case of swallowing disorder. Convergent validity showed an acceptable reliability for the scores of the different questions. CONCLUSION: The questionnaire has shown to be a valid tool for the assessment of the adherence and side-effect management skills for MM patients with IMID treatment.

Safety of ninety-minute daratumumab infusion.

PURPOSE: Daratumumab is the first anti-CD38 monoclonal antibody of the class approved for recurrent and refractory multiple myeloma. Grade 3 and 4 Infusion-Related Reactions (IRRs) are frequent during the first and second infusions. Due to the risks associated with severe IRRs, daratumumab is systematically administered over a period of 3.5 hours.The main objective of this study was to evaluate the safety of a 90-minute daratumumab infusion from the third infusion. PATIENTS AND METHODS: All patients who had received two or more doses of daratumumab in monotherapy or in combination with standard infusion rates were included. We excluded patients enrolled in clinical trials. For the rapid infusion protocol, 20% of the dose was administered over 30 minutes and the remaining 80% over 60 minutes. RESULTS: From April 1 to May 31, 2019, 25 patients received 53 90-minute infusions of daratumumab. Premedication included corticosteroids, antipyretics, antihistamines, and if necessary a leukotriene receptor antagonist. No grade 3 or grade 4 IRRs were observed. CONCLUSION: From the third infusion, we found that a rapid administration of daratumumab (90 vs 210 minutes) was well tolerated and safe. It would be interesting to test this regimen from the second infusion.

Intra-arterial idarubicin_lipiodol without embolization can provide prolonged complete response in hepatocellular carcinoma: A case report.

Hepatocellular carcinoma is the fourth leading cause of cancer death. For unresectable intermediate-stage hepatocellular carcinoma, the standard treatment is transarterial chemoembolization. To date, the overall survival at three years remains low, and there is currently no consensus about the best anticancer agent and optimal treatment regimen. We report the case of a hepatocellular carcinoma patient with a vascular contraindication to embolization who achieved a complete response after four intra-arterial infusions of idarubicin emulsified with lipiodol. The patient maintained his response over a three-year period without any hepatocellular carcinoma treatment, demonstrating the major role of the anticancer agent in the efficacy of transarterial therapies for intermediate-stage hepatocellular carcinoma.

Clinical and economic impact of pharmacist interventions in an ambulatory hematology-oncology department.

OBJECTIVES: To evaluate clinical and financial impact of pharmacist interventions in an ambulatory adult hematology-oncology department. METHODS: All cancer patients receiving a first injectable immuno- and/or chemotherapy regimen were included in this prospective study over a one-year period. The clinical impact of pharmacist interventions made by two clinical pharmacists was rated using the Clinical Economic and Organizational tool. Financial impact was calculated through cost savings and cost avoidance. Main results: Five hundred and fifty-eight patients were included. A total of 1970 pharmacist interventions were performed corresponding to a mean number of 3.5 pharmacist interventions/patient. The clinical impact of pharmacist interventions was classified as negative, null, minor, moderate, major and lethal in 0, 84 (4%), 1353 (68%), 385 (20%), 148 (8%) and 0 cases, respectively. The overall cost savings were €175,563. One hundred and nine (6%) of all pharmacist interventions concerned immuno- or chemotherapy regimen for cost savings of €148,032 (84% of the total amount of cost savings). The cost avoidance was €390,480. Cost avoidance results were robust to sensitivity analyses with cost of preventable adverse drug event as main driver of the model. When the cost of employing a pharmacist was subtracted from the average yearly cost savings plus cost avoidance per pharmacist, this yielded a net benefit of €223,021. The cost-benefit ratio of the clinical pharmacist was €3.7 for every €1 invested. Principal conclusions: To have two full-time clinical pharmacists in a 55-bed ambulatory adult hematology-oncology department is both clinically and financially beneficial.

Idarubicin-loaded Beads for Chemoembolization of Hepatocellular Carcinoma: The IDASPHERE II Single-Arm Phase II Trial.

Background A prior in vitro study showed that idarubicin was the most cytotoxic agent for hepatocellular carcinoma (HCC) cell lines. Idarubicin-loaded beads for transarterial chemoembolization (TACE) were previously evaluated for the appropriate dose in a phase I dose-escalation study. Purpose To evaluate objective response rate (ORR), safety, and survival after TACE by using idarubicin-loaded beads for unresectable HCC. Materials and Methods This prospective single-arm phase II study was conducted between January 2015 and January 2017. Participants with unresectable HCC were included in the trial and underwent TACE with idarubicin-eluting beads. The primary end point was 6-month ORR assessed with independent central review by using modified Response Evaluation Criteria in Solid Tumors. Secondary end points were best ORR during the first 6 months, overall survival, progression-free survival, time to progression, and safety. A two-stage Fleming statistical design was used. Results Forty-six study participants (mean age, 71.2 years ± 10.2; six women and 40 men) were included; 44 participants underwent at least one TACE session. The 6-month ORR was 52% (23 of 44). The best ORR achieved was 68% (30 of 44). Fourteen of 44 (32%) participants underwent a curative treatment after TACE. Median progression-free survival, time to progression, and overall survival were 6.6 months, 9.5 months, and 18.6 months, respectively. TACE was discontinued for toxicity in four of 44 (9%) participants. The most frequent grade 3-4 adverse events were elevated aspartate aminotransferase (14 of 44, 32%), elevated γ-glutamyl transpeptidase (eight of 44, 18%), hyperbilirubinemia (seven of 44, 16%), elevated alanine aminotransferase (seven of 44, 16%), and pain (seven of 44, 16%). Conclusion Idarubicin-eluting beads showed a good safety profile and promising objective response rate and time to progression when used as part of a transarterial chemoembolization regimen for unresectable hepatocellular carcinoma. © RSNA, 2019 See also the editorial by Padia in this issue.

An In Vitro Evaluation of Four Types of Drug-Eluting Embolics Loaded with Idarubicin.

PURPOSE: This study compared loading, elution, and stability of drug-eluting embolic beads (DEBs) loaded with idarubicin. MATERIALS AND METHODS: DC Bead (100-300 µm), HepaSphere (30-60 µm), LifePearl (200 µm), and Tandem (100 µm) DEBs were loaded with 5 mg/mL idarubicin. Loading, elution, diameter changes, loading stability over 2 weeks in storage, and time in suspension were determined for each of the DEBs. RESULTS: Loading of more than 99% of idarubicin was achieved within 15 minutes for LifePearl, DC Bead, and Tandem beads. LifePearl, DC Bead, HepaSphere, and Tandem beads eluted 75% of the total idarubicin released in 13, 24, 42, and 91 minutes, respectively. In vitro elution was completed in 2 hours with 73% ± 3%, 74% ± 3%, 65% ± 6%, and 7% ± 0% of the loaded idarubicin eluted for LifePearl, DC Bead, HepaSphere, and Tandem, respectively. Statistically significant differences were observed at every time point between at least 2 of the products. Overall, in vitro idarubicin elution was rapid and nearly complete for LifePearl, DC Bead, and HepaSphere beads but was minimal and slow from Tandem beads. The average diameter of DEBs after loading was reduced by 5% for LifePearl, whereas it was increased by 9% and 1% for DC Bead and Tandem, respectively. After loading, time in suspension was 11 ± 4 and 10 ± 2 minutes for LifePearl and HepaSphere, respectively, whereas DC Bead and Tandem beads were held in suspension for greater than 20 minutes. CONCLUSIONS: Although all 4 DEBs loaded idarubicin within 15 minutes with minimal changes in diameter, the elution amounts, rates of release, and time in suspension varied.

Intra-arterial idarubicin_lipiodol without embolisation in hepatocellular carcinoma: The LIDA-B phase I trial.

BACKGROUND & AIMS: Idarubicin shows high cytotoxicity against hepatocellular carcinoma (HCC) cells, a high hepatic extraction ratio, and high lipophilicity leading to stable emulsions with lipiodol. A dose-escalation phase I trial of idarubicin_lipiodol (without embolisation) was conducted in patients with cirrhotic HCC to estimate the maximum-tolerated dose (MTD) and to assess the safety, efficacy, and pharmacokinetics of the drug, and the health-related quality of life achieved by patients. METHODS: Patients underwent two sessions of treatment with a transarterial idarubicin_lipiodol emulsion without embolisation. The idarubicin dose was escalated according to a modified continuous reassessment method. The MTD was defined as the dose closest to that causing dose-limiting toxicity (DLT) in 20% of patients. RESULTS: A group of 15 patients were enrolled, including one patient at 10 mg, four patients at 15 mg, seven patients at 20 mg, and three patients at 25 mg. Only two patients experienced DLT: oedematous ascitic decompensation and abdominal pain at 20 and 25 mg, respectively. The calculated MTD of idarubicin was 20 mg. The most frequent grade ≥3 adverse events were biological. One month after the second session, the objective response rate was 29% (complete response, 0%; partial response, 29%) based on modified Response Evaluation Criteria In Solid Tumours. The median time to progression was 5.4 months [95% confidence limit (CI) 3.0-14.6 months] and median overall survival was 20.6 months (95% CI 5.7-28.7 months). Pharmacokinetic analysis of idarubicin showed that the mean Cmax of idarubicin after intra-arterial injection of the idarubicin-lipiodol emulsion is approximately half the Cmax after intravenous administration. Health-related quality of life results confirmed the good safety results associated with use of the drug. CONCLUSIONS: The MTD of idarubicin was 20 mg after two chemolipiodolisation sessions. Encouraging safety results, and patient responses and survival were observed. A phase II trial has been scheduled. LAY SUMMARY: There is a need for transarterial regimens that improve the responses and survival of patients with unresectable HCC. In this phase I trial, we showed that two sessions of treatment with a transarterial idarubicin_lipiodol emulsion without embolisation was well tolerated and gave promising efficacy in terms of tumour control and patient survival.

Efficacy, safety, and cost of pomalidomide in relapsed and refractory multiple myeloma.

OBJECTIVES: To investigate the efficacy, safety, and cost of a pomalidomide-dexamethasone regimen in patients with relapsed and refractory multiple myeloma (RRMM). METHODS: All patients (n = 63) treated with pomalidomide-dexamethasone for RRMM in our university hospital between August 2013 and October 2015 were included. RESULTS: Pomalidomide was discontinued early due to progression (before the 4th cycle) in 17 (27%) patients. No case was discontinued for intolerance. The only independent factor that predicted early pomalidomide discontinuation was time from diagnosis to pomalidomide initiation <3 years. Overall response rate was 51% including complete response in 8%, very good partial response in 25%, and partial response in 19% patients. Thirteen (33%) patients showed stable disease. Median overall survival was 6.4 months in the 17 patients who discontinued pomalidomide early vs 26.8 months in the 14 patients with stable disease vs not achieved in the 32 responders (log-rank; P < 10-3 ). The most common grade ≥3 adverse events were neutropenia (14%) and infections (25%). The incremental cost-effectiveness ratio of pomalidomide-dexamethasone compared with dexamethasone alone was estimated at €39 911 per life-year gained. CONCLUSIONS: The study demonstrated that pomalidomide-dexamethasone regimen has a long-term favorable safety-efficacy profile in RRMM patients. The survival benefit is substantial even in patients with stable disease.

Liver chemoembolization of hepatocellular carcinoma using TANDEM® microspheres.

Transarterial chemoembolization (TACE) combines intra-arterial delivery of a chemotherapeutic agent with selective embolization to obtain a synergistic effect. TACE is recognized as the standard treatment of hepatocellular carcinoma patients at an intermediate stage. If conventional TACE, defined as the injection of an emulsion of a drug with ethiodized oil, still has a role to play, the development of drug-eluting beads has allowed many improvements and optimization of the technique. TANDEM® microspheres are second-generation drug-loadable microspheres. This device raised a special interest due to its tightly calibrated spherical microspheres, with small sizes down to 40 µm available. In this review, we describe the technical characteristics of these microspheres, analyze the scientific literature and hypothesize on the future perspectives.

B cell depleting therapy regulates splenic and circulating T follicular helper cells in immune thrombocytopenia.

B cells are involved in immune thrombocytopenia (ITP) pathophysiology by producing antiplatelet auto-antibodies. However more than a half of ITP patients do not respond to B cell depletion induced by rituximab (RTX). The persistence of splenic T follicular helper cells (TFH) that we demonstrated to be expanded during ITP and to support B cell differentiation and antiplatelet antibody-production may participate to RTX inefficiency. Whereas it is well established that the survival of TFH depends on B cells in animal models, nothing is known in humans yet. To determine the effect of B cell depletion on human TFH, we quantified B cells and TFH in the spleen and in the blood from ITP patients treated or not with RTX. We showed that B cell depletion led to a dramatic decrease in splenic TFH and in CXCL13 and IL-21, two cytokines predominantly produced by TFH. The absolute count of circulating TFH and serum CXCL13 also decreased after RTX treatment, whatever the therapeutic response. Therefore, we showed that the maintenance of TFH required B cells and that TFH are not involved in the inefficiency of RTX in ITP.

Improved stability of lipiodol-drug emulsion for transarterial chemoembolisation of hepatocellular carcinoma results in improved pharmacokinetic profile: Proof of concept using idarubicin.

OBJECTIVES: To investigate the relationship between the improved stability of an anticancer drug-lipiodol emulsion and pharmacokinetic (PK) profile for transarterial chemoembolisation (TACE) of hepatocellular carcinoma (HCC). METHODS: The stability of four doxorubicin- or idarubicin-lipiodol emulsions was evaluated over 7 days. PK and clinical data were recorded after TACE with the most stable emulsion in eight unresectable HCC patients, after institutional review board approval. RESULTS: The most stable emulsion was the one that combined idarubicin and lipiodol (1:2 v:v). At 7 days, the percentages of aqueous, persisting emulsion and oily phases were 50-0-50, 33-0-67, 31-39-30, and 10-90-0 for the doxorubicin-lipiodol (1:1 v:v), doxorubicin-lipiodol (1:2 v:v), idarubicin-lipiodol (1:1 v:v), and the idarubicin-lipiodol (1:2 v:v) emulsion, respectively. After TACE, mean idarubicin Cmax and AUC0-24h were 12.5 ± 9.4 ng/mL and 52 ± 16 ng/mL*h. Within 24 h after injection, 40% of the idarubicin was in the liver, either in vessels, tumours, or hepatocytes. During the 2 months after TACE, no clinical grade >3 adverse events occurred. One complete response, five partial responses, one stabilisation, and one progression were observed at 2 months. CONCLUSION: This study showed a promising and favourable PK and safety profile for the idarubicin-lipiodol (1:2 v:v) emulsion for TACE. KEY POINTS: • Transarterial chemoembolisation (TACE) regimens that improve survival in hepatocellular carcinoma are needed. • Improved emulsion stability for TACE resulted in a favourable pharmacokinetic profile. • Preliminary safety and efficacy data for the idarubicin-lipiodol emulsion for TACE were encouraging.

Idarubicin-loaded ONCOZENE drug-eluting embolic agents for chemoembolization of hepatocellular carcinoma: in vitro loading and release and in vivo pharmacokinetics.

PURPOSE: To present in vitro loading and release characteristics of idarubicin with ONCOZENE (CeloNova BioSciences, Inc, San Antonio, Texas) drug-eluting embolic (DEE) agents and in vivo pharmacokinetics data after transarterial chemoembolization with idarubicin-loaded ONCOZENE DEE agents in patients with hepatocellular carcinoma. MATERIALS AND METHODS: Loading efficacy of idarubicin with ONCOZENE DEE agents 100 µm and DC Bead (Biocompatibles UK Ltd, Farnham, United Kingdom) DEE agents 100-300 µm was monitored at 10, 20, and 30 minutes loading time by high-pressure liquid chromatography. A T-apparatus was used to monitor the release of idarubicin from the two types of DEE agents over 12 hours. Clinical and 24-hour pharmacokinetics data were recorded after transarterial chemoembolization with idarubicin-loaded ONCOZENE DEE agents in four patients with unresectable hepatocellular carcinoma. RESULTS: Idarubicin loading in ONCOZENE DEE agents was > 99% at 10 minutes. Time to reach 75% of the release plateau level was 37 minutes ± 6 for DC Bead DEE agents and 170 minutes ± 19 for ONCOZENE DEE agents both loaded with idarubicin 10 mg/mL. After transarterial chemoembolization with idarubicin-loaded ONCOZENE DEE agents, three partial responses and one complete response were observed with only two asymptomatic grade 3 biologic adverse events. Median time to maximum concentration for idarubicin in patients was 10 minutes, and mean maximum concentration was 4.9 µg/L ± 1.7. Mean area under the concentration-time curve from 0-24 hours was equal to 29.5 µg.h/L ± 20.5. CONCLUSIONS: ONCOZENE DEE agents show promising results with very fast loading ability, a favorable in vivo pharmacokinetics profile with a sustained release of idarubicin during the first 24 hours, and encouraging safety and responses. Histopathologic and clinical studies are needed to evaluate idarubicin release around the DEE agents in tumor tissue and to confirm safety and efficacy.
