    Abstract Introduction: Chemotherapy-induced polyneuropathy (CIPN) and post-chemotherapy cognitive impairment (PCCI) are frequent side effects of paclitaxel treatment. CIPN/PCCI are potentially irreversible, reduce quality of life and often lead to treatment limitations, which affect patients' outcome. We previously demonstrated that paclitaxel enhances an interaction of the Neuronal calcium sensor-1 protein (NCS-1) with the Inositol-1,4,5-trisphosphate receptor (InsP
    Methods and analysis: The PREPARE study will be conducted as a multicenter, randomized, double-blind, placebo-controlled phase-2 trial with parallel group design.
    Ethics and dissemination: The study protocol was approved by the Berlin ethics committee (reference: 21/232 - IV E 10) and the respective federal agency (Bundesinstitut für Arzneimittel und Medizinprodukte, reference: 61-3910-4044771).

    Abstract Health technology assessment (HTA) of clinical and economic value of a new intervention is an integral step in providing the access of patients to innovative cancer care and treatment. Overall survival (OS) is the preferred criterion for demonstrating the therapeutic efficacy in HTA given its direct clinical and patient relevance. However, with often long life expectancy of patients with early cancer, analysis of OS becomes less practical. Partially due to this reason, pathological complete response (pCR) and time-to-event end-points like disease-free survival are frequently incorporated into the pivotal clinical trials in the neoadjuvant and adjuvant settings. However, there exists a discrepancy between different national HTA bodies regarding the acknowledgement of patient relevance of these end-points. In this article, we analysed the perspectives of patients on different aspects of end-points used in clinical trials in early cancer. Gathered evidence strongly suggests that complete tumour eradication and reduced risk of recurrence provide important psychological benefits thus signifying that pCR and time-to-event end-points are directly relevant to patients. Additionally, we reviewed opinions on patient relevance of neoadjuvant and adjuvant therapy end-points adopted by HTA bodies during the recent evaluations. We found that improvements in end-points used in the adjuvant setting were commonly considered as valuable to patients. In contrast, opinions on patient relevance of neoadjuvant therapy end-points varied between the national HTA bodies. Universal acknowledgement of patient relevance of therapeutic end-points for early cancer by HTA bodies is necessary to balance the inequality in uptake of innovative therapies into national healthcare systems.

    Abstract Introduction: Patients with metastatic NSCLC (mNSCLC) treated with immune checkpoint inhibitors in clinical practice may often not meet the strict inclusion criteria of clinical trials. Our aim was to assess the trial eligibility of patients with mNSCLC treated with pembrolizumab monotherapy in real-world and to compare the outcome of "trial-ineligible" and "potentially trial-eligible" patients.
    Methods: Data from the prospective, clinical research platform CRISP were used to compare patient characteristics, treatment, and outcome of patients with programmed cell death-ligand 1 tumor proportion score greater than or equal to 50% tumors treated with pembrolizumab monotherapy who are deemed either "potentially trial-eligible" or "trial-ineligible" according to inclusion and exclusion criteria of the registrational studies (KEYNOTE-024 and -042).
    Results: Of 746 patients included, 343 patients (46.0%) were classified as "trial-ineligible" and had significantly worse outcomes compared with "potentially trial-eligible" patients (n = 403, 54.0%): median progression-free survival: 6.2 (95% confidence interval [CI]: 5.2-8.4) versus 10.3 (95% CI: 8.4-13.8) months, hazard ratio (trial-ineligible versus potentially trial-eligible) of 1.43 (95% CI: 1.19-1.72),
    Conclusions: Our data reveal that a considerable proportion of patients with mNSCLC are not eligible to participate in a clinical trial and were found to have worse outcomes than potentially trial-eligible patients, whose outcomes were comparable with those obtained from pivotal clinical trials. This is of substantial clinical relevance for physicians discussing outcomes to be expected with their patients and stresses the need for real-world effectiveness analyses.

    Abstract Diagnosis of hepatitis E virus (HEV) is usually determined serologically by detection of the presence of immunoglobulin (Ig)M antibodies or rising anti-HEV IgG titers. However, serological assays have demonstrated a significant variation in their sensitivities and specificities. In this study, we present the systematic comparison of different immunological anti-HEV assays using complete seroconversion panels of 10 virologically confirmed HEV genotype 3 infected individuals. Assay sensitivities were further evaluated by testing serially diluted World Health Organization (WHO) reference reagent for hepatitis E virus antibody and one patient sample infected with HEV genotype 3. Anti-HEV IgM and IgG antibody presence was determined using the immunological assays Wantai HEV IgM/IgG enzyme-linked immunosorbent assay (ELISA) (Sanbio, Uden, The Netherlands), recomWell HEV IgM/IgG (Mikrogen, Neuried, Germany), HEV IgM ELISA 3.0, HEV ELISA, HEV ELISA 4.0, Assure HEV IgM Rapid Test (all MP Biomedicals Europe, Illkirch Cedex, France) and Anti-HEV ELISA (IgM/IgG, Euroimmun, Lübeck, Germany). The assays showed differences regarding their analytical and diagnostic sensitivities, with anti-HEV IgM assays (n = 5) being more divergent compared to anti-HEV IgG (n = 4) assays in this study. Considerable variations were observed particularly for the detection period of IgM antibodies. This is the first study systematically characterizing serologic assays on the basis of seroconversion panels, providing sample conformity for a conclusive comparison. Future studies should include the assay comparison covering the four different genotypes.

  9. Article ; Online: Improving putrescine production by Corynebacterium glutamicum by fine-tuning ornithine transcarbamoylase activity using a plasmid addiction system.

    Abstract: ... of the key enzyme N-acetylglutamate kinase (ArgB) by L-arginine, a plasmid addiction system for low-level ...

    Abstract Corynebacterium glutamicum shows a great potential for the production of the polyamide monomer putrescine (1,4-diaminobutane). Previously, we constructed the putrescine-producing strain PUT1 by deletion of argF, the gene for ornithine transcarbamoylase (OTC), and argR, encoding the L-arginine repressor, combined with heterologous expression of the Escherichia coli gene for L-ornithine decarboxylase SpeC. As a consequence of argF deletion, this strain requires supplementation of L-arginine and shows growth-decoupled putrescine production. To avoid costly supplementation with L-arginine and the strong feedback inhibition of the key enzyme N-acetylglutamate kinase (ArgB) by L-arginine, a plasmid addiction system for low-level argF expression was developed. By fine-tuning argF expression through modifications of the promoter, the translational start codon and/or the ribosome binding site, high productivity and titer could be obtained. OTC activity varied almost thousandfold between 960 and 1 mU mg⁻¹ resulting in putrescine yields on glucose from less than 0.001 up to 0.26 g g⁻¹, the highest yield in bacteria reported to date. The most promising strain, designated PUT21, was characterized comprehensively. PUT21 strain grew with a rate of 0.19 h⁻¹ in mineral salt medium without the need for L-arginine supplementation and produced putrescine with a yield of 0.16 g g⁻¹ glucose at a volumetric productivity of 0.57 g L⁻¹ h⁻¹ and a specific productivity of 0.042 g g⁻¹ h⁻¹. The carbon balance suggested that no major unidentified by-product was produced. Compared to the first-generation strain PUT1, the putrescine yield observed with PUT21 was increased by 60%. In fed-batch cultivation with C. glutamicum PUT21, a putrescine titer of 19 g L⁻¹ at a volumetric productivity of 0.55 g L⁻¹ h⁻¹ and a yield of 0.16 g g⁻¹ glucose could be achieved. Moreover, while plasmid segregation of the initial strain required antibiotic selection, plasmid segregation in C. glutamicum PUT21 was fully stable for more than 60 generations without antibiotic selection even in the presence of L-arginine. The ornithine decarboxylase gene speC was expressed from this argF addiction plasmid ensuring stable putrescine production by the engineered C. glutamicum strain.
