This international, multi-centre, double-blind vaccine study is a three-arm prospective 1:1:1 randomisation comparing each of two experimental combination vaccine regimens i.e. DNA/AIDSVAX (weeks 0,4,24,48) and DNA/CN54gp140 (weeks 0,4) + MVA/CN54gp140 (weeks 24,48) with placebo control. There will be a concurrent open-label 1:1 randomisation to compare daily TAF/FTC (week 0-26) to daily TDF/FTC (weeks 0-26) as pre-exposure prophylaxis.
The study aims to randomise up to 1668 eligible adults (18-40 years) through collaborating clinical research centres in 4 countries (Mozambique; South Africa; Tanzania; and Uganda). Each participant will be followed for a minimum of 74 weeks after enrolment.
The trial is designed to detect a reduction in HIV incidence that has public health relevance sufficient to justify implementation of the combination vaccine regimen. In light of the high level of effectiveness demonstrated in the PrEP trials (up to 86% reduction in HIV), this trial is powered to detect a protective vaccine efficacy of 70% at the final analysis.
The PrEP component will determine whether the effectiveness of TAF/FTC is unacceptably lower than the effectiveness of TDF/FTC.

NCT02390063 / CompletedPhase 1IIT

A Randomized Phase I Study to Determine the Safety and Immunogenicity of ChAd-MVA Vaccination Compared to MVA Alone With and Without Low Dose Cyclophosphamide in Low and Intermediate Risk Localised Prostate Cancer

This is a clinical trial of a new treatment for prostate cancer that is a type of vaccine that could be a new way to treat cancer. A vaccine that could alert the immune system to the presence of cancer cells in the body may enable the immune system to target and kill those cells effectively. This vaccine is intended to work by making the immune system kill cells that have a special protein (called 5T4) that is present on the surface of cancer cells. The vaccine is made up of two recombinant viruses ("ChAdOx1" and "MVA") that have been designed to produce the 5T4 protein and have been modified so that they are weakened and cannot reproduce themselves within the body like normal viruses. Once injected into the body, these viruses make the 5T4 protein and help the body's immune system to learn to target this protein and destroy cancer cells.
This is a first-in-human study to evaluate the safety and immunogenicity of ChAdOx1.5T4-MVA.5T4 vaccination regime. It is evaluated in neo-adjuvant setting in low and intermediate risk localised prostate cancer patients who have either decided to have their prostate removed or are stable on active surveillance.

BACKGROUNDOFA (Opioid-free anesthesia) has the potential to reduce the occurrence of opioid-related adverse events and enhance postoperative recovery. Our research aimed to investigate whether OFA, combining esketamine and dexmedetomidine, could serve as an alternative protocol to traditional OBA (opioid-based anesthesia) in shoulder arthroscopy, particularly in terms of reducing PONV (postoperative nausea and vomiting).METHODSA total of 60 patients treated with shoulder arthroscopy from September 2021 to September 2022 were recruited. Patients were randomly assigned to the OBA group (n = 30) and OFA group (n = 30), receiving propofol-remifentanil TIVA (total intravenous anesthesia) and esketamine-dexmedetomidine intravenous anesthesia, respectively. Both groups received ultrasound-guided ISBPB(interscalene brachial plexus block)for postoperative analgesia.RESULTSThe incidence of PONV on the first postoperative day in the ward (13.3% vs. 40%, P < 0.05) was significantly lower in the OFA group than in the OBA group. Moreover, the severity of PONV was less severe in the OFA group than in the OBA group in PACU (post-anesthesia care unit) (0 [0, 0] vs. 0 [0, 3], P<0.05 ) and in the ward 24 h postoperatively ( 0 [0, 0] vs. 0 [0, 2.25], P<0.05). Additionally, the OFA group experienced a significantly shorter length of stay in the PACU compared to the OBA group (39.4 ± 6.76 min vs. 48.7 ± 7.90 min, P < 0.001).CONCLUSIONSCompared to the OBA with propofol-remifentanil, the OFA with esketamine- dexmedetomidine proved to be feasible for shoulder arthroscopy, resulting in a reduced incidence of PONV and a shorter duration of stay in the PACU.TRIAL REGISTRATIONThe Chinese Clinical Trial Registry (No: ChiCTR2100047355), 12/06/2021.

BackgroundImmunotherapy directed at 5T4 tumor antigen may delay the need for further chemotherapy. An attenuated modified vaccinia Ankara virus containing the gene encoding for 5T4 (MVA-5T4) was studied in asymptomatic relapsed ovarian cancer.ObjectiveTo assess the effectiveness and safety of MVA-5T4 as treatment for asymptomatic relapsed ovarian cancer.MethodsTRIOC was a phase II randomized (1:1), placebo-controlled, double-blind multicenter study. The primary aim was to assess the effectiveness and safety of MVA-5T4 as a treatment for asymptomatic patients with relapsed ovarian cancer. Eligible patients had International Federation of Gynecology and Obstetrics (FIGO) stage IC1–III or IVA epithelial ovarian, fallopian tube, or primary peritoneal carcinoma, Eastern Cooperative Oncology Group (ECOG) 0–1, with relapse defined by a rise in CA-125 to twice the upper limit of normal or low-volume disease on CT scan. The primary endpoint was disease progression (including deaths from ovarian cancer) at 25 weeks. Following a brief suspension, the trial restarted as a single-arm study. The revised single-arm design required 45 evaluable patients treated with MVA-5T4 to detect a 25-week progression rate of 50%, assuming an expected 70% rate without MVA-5T4; 85% power with one-sided 5% significance.ResultsA total of 94 eligible patients were recruited, median age was 65 years (range 42–82), median follow-up 34 months (range 2–46). Overall, 59 patients received MVA-5T4 and 35 patients received placebo. The median number of MVA-5T4 injections received was 7 (range 0–9), compared with a median of 6 (range 1–12) for patients receiving placebo. Median progression-free survival was the same in both arms (3.0 months). The 25-week progression rate was similar in both arms: 80.0% for patients treated with MVA-5T4 and 85.7% for those receiving placebo (risk difference −5.7%, 95% CI −21.4% to 10.0%). Median time to clinical intervention was improved with MVA-5T4: 7.6 months (range 6.7–9.5) vs 5.6 (range 4.9–7.6),ConclusionMVA-5T4 vaccination in patients with asymptomatic relapse was well-tolerated but did not improve the progression rate at 25 weeks. The majority of patients who received MVA-5T4 had clinical intervention later than those assigned to placebo.Trial registration numberNCT01556841 .

Feasibility of opioid-free anesthesia in laparoscopic radical prostatectomy: A retrospective, quasi-experimental study

Article

Author: Tejedor, Ana ; García, Marta ; Bijelic, Lana

AbstractBackground and Aims:Opioid-free anesthesia (OFA) provides adequate analgesia minimizing opioids. OFA has not been evaluated in laparoscopic radical prostatectomy (LRP). Our aim was to evaluate OFA feasibility and its effectiveness in LRP.Material and Methods:A quasi-experimental retrospective study of 55 adult patients undergoing LRP was performed from September 2020 until December 20223. Predefined protocols for either opioid-based anesthesia (OBA; with continuous remifentanil infusion) or OFA (continuous lidocaine, dexmedetomidine, and ketamine infusion) were followed. In both groups, wound infiltration was performed before skin incision. Primary outcome was postoperative pain management (numerical rating scale [NRS]) in the first 24 postoperative hours. Secondary outcomes were opioid consumption, start to sitting and ambulation, postoperative complications, and length of hospital stay.Results:OFA protocol patients had better median pain scores during movement at 1, 18 and 24 h, that is, 1 (interquartile range [IQR] 0–3) versus 2.5 (IQR 0–4), P = 0.047; 0 (IQR 0–1) versus 1 (IQR 0–2), P = 0.017; and 0 (IQR 0–0.25) versus 1 (IQR 0–2), P = 0.013, respectively. At 6 and 12 h, there were no statistically significant differences, that is, 0.5 (IQR 0–2) versus 1 (IQR 0–2), P = 0.908 and 1 (IQR 0–2) versus 0.5 (IQR 0–2), P = 0.929, respectively. Lower morphine requirements were recorded in the first 18 and 24 postoperative hours, that is, 0 (IQR 0–0) versus 1 (IQR 0–2.75) mg, P = 0.028 and 0 (IQR 0–2) versus 1.5 (IQR 0–3) mg, P = 0.012, respectively. Start to sitting and ambulation occurred earlier in the OFA group (P = 0.030 and P = 0.002, respectively). Linear regression showed that ambulation was independently associated with the analgesic technique (P = 0.034). Only one patient had postoperative nausea and vomiting (PONV) and belonged to the OBA group. There was no difference in total complications or the length of stay.Conclusion:In this study, OFA strategy was found to be safe, feasible, and provided adequate analgesia, minimizing the use of postoperative opioids, and was independently associated with earlier ambulation.
