A multicenter phase II trial of anti-EGFR-immunoliposomes loaded with doxorubicin in patients with advanced triple negative breast cancer.

Advanced triple negative breast cancer (TNBC) is an aggressive, but initially chemo-sensitive disease. The prognosis is poor and more than three quarters of patients experience progression 12 months after the initiation of conventional first-line chemotherapy. Approximately two thirds of TNBC express epidermal growth factor receptor 1 (EGFR).

Investigational medicinal products, related costs and hospital pharmacy services for investigator-initiated trials: A mixed-methods study.

Background: Conducting high quality investigator-initiated trials (IITs) is challenging and costly. The costs of investigational medicinal products (IMPs) in IITs and the role of hospital pharmacies in the planning of IITs are unclear. We conducted a mixed-methods study to compare planned and actual costs of IMPs in Swiss IITs, to examine potential reasons for differences, and to gather stakeholder views about hospital services for IITs.

Targeting immunoliposomes to EGFR-positive glioblastoma.

Background: We assessed the capacity of epidermal growth factor receptor (EGFR)-targeted immunoliposomes to deliver cargo to brain tumor tissue in patients with relapsed glioblastoma harboring an EGFR amplification. We aimed to assess the tolerability and effectiveness of anti-EGFR immunoliposomes loaded with doxorubicin (anti-EGFR ILs-dox) in glioblastoma multiforme patients.

Patients And Methods: Patients with EGFR-amplified, relapsed glioblastoma were included in this phase I pharmacokinetic trial.

A meta-research study revealed several challenges in obtaining placebos for investigator-initiated drug trials.

Objectives: To systematically assess the kind of placebos used in investigator-initiated randomized controlled trials (RCTs), from where they are obtained, and the hurdles that exist in obtaining them.

Study Design And Setting: PubMed was searched for recently published noncommercial, placebo-controlled randomized drug trials. Corresponding authors were invited to participate in an online survey.

Single-dose versus 3-day cotrimoxazole prophylaxis in transurethral resection or greenlight laser vaporisation of the prostate: study protocol for a multicentre randomised placebo controlled non-inferiority trial (CITrUS trial).

Background: Transurethral resection of the prostate (TURP) and Greenlight laser vaporisation (GL) of the prostate are frequently performed urological procedures. For TURP, a single-dose antimicrobial prophylaxis (AP) is recommended to reduce postoperative urinary tract infections. So far, no international recommendations for AP have been established for GL.

Improved Muscle Function in Duchenne Muscular Dystrophy through L-Arginine and Metformin: An Investigator-Initiated, Open-Label, Single-Center, Proof-Of-Concept-Study.

Unlabelled: Altered neuronal nitric oxide synthase function in Duchenne muscular dystrophy leads to impaired mitochondrial function which is thought to be one cause of muscle damage in this disease. The study tested if increased intramuscular nitric oxide concentration can improve mitochondrial energy metabolism in Duchenne muscular dystrophy using a novel therapeutic approach through the combination of L-arginine with metformin. Five ambulatory, genetically confirmed Duchenne muscular dystrophy patients aged between 7–10 years were treated with L-arginine (3 x 2.

Large-scale manufacturing of GMP-compliant anti-EGFR targeted nanocarriers: production of doxorubicin-loaded anti-EGFR-immunoliposomes for a first-in-man clinical trial.

We describe the large-scale, GMP-compliant production process of doxorubicin-loaded and anti-EGFR-coated immunoliposomes (anti-EGFR-ILs-dox) used in a first-in-man, dose escalation clinical trial. 10 batches of this nanoparticle have been produced in clean room facilities. Stability data from the pre-GMP and the GMP batch indicate that the anti-EGFR-ILs-dox nanoparticle was stable for at least 18 months after release.

Tolerability, safety, pharmacokinetics, and efficacy of doxorubicin-loaded anti-EGFR immunoliposomes in advanced solid tumours: a phase 1 dose-escalation study.

Background: Results of preclinical studies have shown that EGFR immunoliposomes have substantial antitumour effects. We aimed to assess the tolerability, safety, pharmokinetics, and efficacy of anti-EGFR immunoliposomes loaded with doxorubicin (anti-EGFR ILs-dox) in patients with solid tumours.

Methods: In this first-in-man, open-label, phase 1 clinical study, we enrolled patients at University Hospital of Basel, Switzerland, who had EGFR-overexpressing advanced solid tumours no longer amenable to standard treatment.

Intranasal midazolam: pharmacokinetics and pharmacodynamics assessed by quantitative EEG in healthy volunteers.

The pharmacokinetics and pharmacodynamics of a highly concentrated cyclodextrin-based intranasal (i.n.) midazolam formulation containing the absorption-enhancer chitosan were studied in 12 healthy volunteers and compared with intravenous (i.

Dose calculation in opioid rotation: electronic calculator vs. manual calculation.

Objective: To generate, validate and establish a web-based individualised opioid conversion calculator at the University Hospital Basel and to analyse its value and significance.

Setting: A 700-bed university hospital.

Method: Published data were screened by a Medline search using the keywords: opioid, rotation, switching, potency and dose ratio.

Implementation of treatment guidelines to support judicious use of antibiotic therapy.

Background And Objective: Judicious use of antibiotics is essential considering the growth of antimicrobial resistance and escalating costs in health care. This intervention study used treatment guidelines to improve antibiotic therapy by changing prescribing practice.

Methods: A before-after intervention study was performed in a 550-bed tertiary care teaching hospital in Switzerland, with an additional follow-up analysis 1 year later.
