The appearance and increase in the quantity and proportion of the clinical research coordinator’s service fee in drug clinical trial research fund and its impact on trial quality

Objective The changes of absolute value and relative value of clinical research coordinator service fee and its influence on the quality of drug clinical trial were analyzed. Methods This study compared the amount and structural changes of drug clinical trial costs in before 3 years and after 3 years of self-examination and inspection initiated by the China Food and Drug Administration, identified the increase number and composition of each individual cost of a clinical trial research funds which including clinical research coordinator service fee, investigator labor fee, subjects examination fee, subjects traffic subsidy, documents management fee, drug management fee, etc. Result The most significant appearance of increase in volume and proportion was the clinical research coordinator service fee. From the initial few to the global multicenter tumor drug clinical trials RMB31,624 or 34.92% of the proportion and domestic multicenter tumor drug clinical trials RMB16,500, accounted for 33.74%. Discussion It has become common for more money to be spent on clinical trials to be accompanied by improved quality, but the occurrence and continuous increase of clinical research coordinator service fee were divided into two aspects, On the one hand, the quality of clinical trials was promoted by the large amount of low-skill trivial work undertaken by clinical research coordinator; on the other hand, the quality of clinical trials was undermined by the fact that clinical research coordinator did too much treatment evaluation work that should have been done by the investigator. Conclusion The clinical research coordinators’ access standards, pre-employment training and examination, job and performance evaluation, in addition to the SMO specification management and avoiding malicious competition between the industry, are important factors in the quality assurance of drug clinical trials.

Current Situation of Clinical Trials of Drugs for Children's Indications in China

Background: The number of pediatric outpatient visits in the general hospitals of China shows an increasing trend year by year. To analyze the current situation of clinical trials of drugs with indications for children in China in order to provide references for research and development of drugs for children and in formulating relevant policies. Methods: Drug clinical trials with indications for children registered before January 9, 2020 were retrieved based on the drug clinical trial registration and information publicity platform. The data were extracted and statistically analyzed by excel 2010 and SPSS 22.0, respectively. Results: There were 256 clinical trials of drugs with indications for children, which accounted for 2.61% of the total registered trials. The overall average annual growth rate of the number of trials from 2007 to 2019 was 43.30% (P=0.0000). The host company and the lead organization were mainly located in the eastern and northern parts of China. There were 67 trials (26.17%) with children as subjects; 102 trials (39.84%) with research drugs only for children; the drug type was mainly the chemical drug, and indications mainly included infections, nervous and mental diseases and respiratory diseases. Conclusion: The prospects associated with pediatric drug development are positive, but it still needs new incentives or technical guidance to further promote.

Present era of drug safety in India: An overview

Introduction: Common Adverse Drug Reactions (ADR), evaluated by drug clinical trial studies, whereas an individual or specific population might suffer reactions after prolonged dormancy. Pharmacovigilance (PV) is a scientific investigation dealing with and keeping regular vigil on the drugs being used. Methods: The Indian Pharmacopoeia Commission (IPC) and other regulatory authorities like a National Coordination Committee (NCC) via the Central Drug Standard Control Organization (CDSCO) manage PV activity in synchronicity. Indian Pharmacovigilance (PV) system requires carving, therefore the Pharmacovigilance Program of India (PvPI) was enforced by the government in the year 2010, relying on exact ADR detection, evaluation, and reporting. Results: Thus, several regional, zonal and peripheral centers are developed for ADR reporting. Clinicians, Nurses, laypersons, pharmacists, and other healthcare professionals can fill ADR reporting forms online or offline at the nearest centers in suitable languages. Additionally, a toll-free number and mobile app could be used for reporting ADR. Every reported ADR gets collected and processed at the centers through Vigi-flow software, which detects and assesses the signal strength reported at CDSCO and World Health Organisation (WHO) for the required regulatory action. Conclusions: The final decision of CDSCO-WHO is passed by a suitable media source for the advancement of society's health.

Folate pathway gene expression in metastatic colorectal cancer patients treated with arfolitixorin/5-FU-based chemotherapy.

99 Background: Arfolitixorin is the natural, biologically active form of the marketed folates and is expected to be efficacious in a larger proportion of patients with less inter- and intra-individual variability compared with e.g. leucovorin. We have previously found a positive correlation between survival and expression of folate pathway genes in stage III/IV CRC treated with 5-fluorouracil/leucovorin (5-FU/LV). Low expression of folate-related genes may lead to poor response to 5-FU/LV-based treatment, since suboptimal transport and metabolization of LV yield insufficient active [6R]-5,10-methylenetetrahydrofolate and weak inhibition of the target enzyme thymidylate synthase (TYMS). The aim of the present study was to investigate possible confounders and biomarkers of arfolitixorin/5-FU-based treatment in relation to safety and response in a phase I/IIa metastatic colorectal cancer (mCRC) trial. Methods: ISO-CC-005 is a multi-center, phase I/IIa study in mCRC patients eligible for 5-FU/folate therapy alone or in combination with irinotecan or oxaliplatin ± bevacizumab. Patients were also treated with different doses of arfolitixorin as a single or double bolus. The study investigated safety and tolerability of arfolitixorin, and anti-tumor activity was evaluated by overall response rate (ORR) per RECIST v1.1 after 4 cycles of chemotherapy. RNA was prepared from FFPE tumor tissue, reverse transcribed and used for gene expression profiling. The following genes of interest were evaluated: ABCC3, MTHFD2, SLC46A1, SLC19A1, SLC25A32 and TYMS. An ANOVA test was used to rule out potential biases in the baseline expression levels of the genes and to assess the potential association with clinical response. Results: Eighty-one (77.1%) of 105 patients provided material for this analysis. A lower pre-treatment expression of TYMS was associated with clinical benefit (PR and SD; p = 0.021). No clear association was identified between the gene expression markers and the number of adverse events. Gender was not significantly associated with differences in gene expression. Conclusions: Low pre-treatment expression levels of TYMS were associated with clinical benefit (PR and SD) following treatment. Given the role of this gene in the folate metabolic pathways we plan to further assess its predictive potential on a larger cohort during our ongoing global phase III AGENT study. In parallel an assessment of the expression of the other candidate genes on specific patient sub-groups is currently ongoing. These studies will provide additional cues on the use of these genes as predictive markers for treatment outcome and their role in the mode of action of the drug.

Activity of cabazitaxel in patients with metastatic or inoperable locally advanced dedifferentiated liposarcoma: European Organization for Research and Treatment of Cancer (EORTC) Phase II trial 1202.

11556 Background: The optimal treatment for patients with advanced dedifferentiated (DD) liposarcoma (LPS) remains uncertain. Single agents which are most effective include doxorubicin and ifosfamide but, as with soft tissue sarcomas (STS) in general, objective response rates (ORR) and progression free survival (PFS) are very modest. Cabazitaxel exerts its effect through inhibition of microtubular disassembly and has been shown to be relatively safe, effective and well-tolerated. EORTC 1202 assessed whether cabazitaxel demonstrated sufficient antitumor activity in patients with metastatic or inoperable locally advanced DD LPS to justify further investigation in a phase III setting. Methods: This was an international multi-center, open label single arm phase II trial. Eligible patients with metastatic or inoperable locally advanced DD LPS were treated with cabazitaxel 25mg/m² IV infusion over 1 hour every 21 days. Primary endpoint was PFS rate at 12 weeks assessed by local investigator per RECIST 1.1. Based on a Simon two-stage design, at least 4 out of 17 (Stage 1) and 11 out of 37 (Stage 2) eligible and evaluable patients who are progression-free at 12 weeks were needed. Results: Forty patients were registered by 10 institutions in 4 countries between March 2015 and March 2019, with 2 patients being ineligible. Among the 38 eligible patients who started treatment, 3 (7.5 %) were still on treatment at the time of analysis. The number of cycles ranged from 1 to 30, with a median of 5; 26 patients (65%) received at least 4 cycles of cabazitaxel. Among the first 17 (Stage 1) and 37 (Stage 2), 11 and 20 patients were progression-free at 12 weeks respectively, satisfying the study decision rules. The PFS rate at 12 weeks for all 38 eligible patients was 52.6% (conditional 1-sided 95 % CI 38.3 – 100). Two patients (5.3%) achieved a confirmed partial response (PR) and 23 stable disease (SD) (60.5%). Disease control (PR+SD) was achieved in 25 patients (65.8%). Median PFS was 7.4 months (95%CI 2.8-10.3). The most common cabazitaxel -related grade >3 adverse events in all 40 registered patients were neutropenia (60%), febrile neutropenia (25%), fatigue (12.5%), and anemia (10%). There were no cabazitaxel-related deaths. Conclusions: EORTC 1202 met its primary endpoint, with 20/37 pts (54%) being progression-free at 12 weeks. Results of this trial confirm activity of cabazitaxel in patients with metastatic or inoperable locally advanced DD LPS and warrant further exploration of the drug.
