‘Risk Management Plan Educational Materials’ (RMP EMs) are additional risk minimization measures (aRMMs) intended to prevent or reduce the occurrence of adverse reactions associated with the exposure to a medicine, or to reduce their severity or impact on the patient. While the healthcare sector is embracing various digital tools and platforms for educational and/or awareness building purposes, paper-based materials have remained the mainstay approach for implementation of aRMMs by pharmaceutical companies. Novartis in Singapore conducted a pilot on the feasibility of distributing electronic copies of RMP EMs (e-RMP). Post-pilot, e-RMP was officially implemented in Novartis Singapore. A year following the launch of e-RMP, a survey was performed with healthcare professionals (HCPs) to understand end-users’ experience. The survey responses revealed a general preference by both HCPs and patients towards e-RMP. Digital methods of delivering educational aRMMs offer great benefits over traditional paper-based programs. e-RMP significantly reduces the time needed for updated RMP EMs to reach HCPs and their patients/caregivers. This is important to ensure that HCPs and patients/caregivers are made aware of any updates in key safety messages of the products in a timely manner to ultimately ensure patient safety. The successful transition to digital solutions requires purposeful collaborations between key stakeholders of the healthcare ecosystem including regulatory authorities, pharmaceutical companies, HCPs, patients and caregivers. This article aims to provide insights on the digitalization journey of e-RMP, a case study in Singapore, outlining the value but also some of the challenges faced during this transformation.

BackgroundApproximately 30–70% of patients who have undergone allogeneic (allo) hematopoietic stem cell transplantation (HSCT) eventually experience chronic graft-versus-host disease (cGVHD). Patients who develop steroid-refractory (SR)-cGVHD are the most severely impacted due to significant disease and financial burden. There remains an unmet need for safe, efficacious, and accessible treatments for these patients. The objective of this study was to determine the cost effectiveness of ruxolitinib for treatment of SR-cGvHD from the Singapore healthcare system perspective.MethodsBased on data from the REACH3 randomized open-label trial, a semi-Markov model was developed to evaluate cost-effectiveness of ruxolitinib compared with investigators' choice of best alternative therapy (BAT) for treatment of patients > 12 years of age with SR-cGVHD in Singapore over a 40-year time horizon. The model only considered direct medical-care costs related to the treatment of SR-cGVHD and reported them in Singapore Dollars (SGD). Half-cycle correction was applied to all costs and outcomes, which were discounted at 3%. Probabilistic sensitivity analysis (PSA), one-way sensitivity analysis (OWSA), and scenario analysis were conducted to explore the drivers of uncertainty in the model.ResultsIn the deterministic base case, more life years (LY; 10.28 vs. 9.42) and quality-adjusted life years (QALYs; 7.31 vs. 6.51) were gained with ruxolitinib than BAT at higher costs (SGD 303,214 vs. SGD 302,673) leading to an incremental cost-effectiveness ratio (ICER) of SGD 677/QALY. At a willingness-to-pay threshold of SGD 75,000/QALY gained, PSA found that ruxolitinib had a 78.52% probability of being cost-effective. Findings were sensitive to variations in non-responder utilities in the BAT arm and duration of BAT treatment in the OWSA, or comparison to either methotrexate (MTX) or mycophenolic acid as a single comparator in the scenario analysis. ICERs remained lower than SGD 75,000/QALY in all other tested variations and scenarios.ConclusionRuxolitinib is likely to be cost-effective from Singapore healthcare system’s perspective for patients with SR-cGVHD, which is promising in the management of patients with unmet clinical needs.

Novel therapeutic options for cancer offer hope for patients and their families, particularly when the cancer has not responded to established treatment regimens. The CAR-T cell therapeutic approach has changed the treatment paradigm for relapsed or refractory lymphoma, extending the capacity of the patient's own T cells to detect and eliminate cancer cells through genetic modification of T-cell surface receptors. The process of establishing treatment centers and developing clinical expertize in this novel treatment strategy is complex. Time, resources, and a commitment to focusing health budgets on a new area are required. Currently, Singapore is the only country in southeast and south Asia with market authorization of the CAR-T product, tisagenlecleucel. Availability of CAR-T treatment across international borders provides patients in neighboring countries with choice in therapeutic options. This paper describes the unique hub-and-spoke cross-border collaboration developed between Singapore and its neighbors to provide access to CAR-T cell therapy for patients with relapsed or refractory lymphoma. To date in 2022, four patients have been included in the CAR-T treatment cross-border collaboration. Their stay in Singapore has been at least 2months' duration, including the pre-treatment evaluation, apheresis, CAR-T cell infusion and post-treatment monitoring. Patient support from referring and treating physicians, critical to the success of the undertaking, is characterized by early communication, patient selection, multi-disciplinary care, post-treatment monitoring, and attention to detail. The patient journey and the development and implementation of this unique collaboration are discussed.

Background: iPSCs, with many mutations or epigenetic modifications, are in a unique aging state and have pluripotent properties. Previously, we reported that hsa-miR-520d-5p reverted fibroblasts to mesenchymal stem cells (MSCs) and converted approximately half of the mutations in cancer cells back to wild-type alleles. Objective: We focused on the genes involved in the hair life cycle comprising 4 phases and examined whether 520d-5p can convert iPSCs with mutation(s) to less-mutated status during the differentiation to MSCs. Materials and methods: Using next-generation sequencing analysis, we compared the effect of 520d-5p on the mutation level in 177 hair life cycle-related genes in iPSCs to that in iPSC-differentiated MSCs. Results: Transfection by hsa-miR-520d-5p induced genetic improvement in 79.7% (141/177) of the genes and reverted 17.7% (25/141) to wild type; the average conversion rate was 54.4%. The hsa-miR-520d-5p-induced genes, including the function of dermal papilla cells or bulge stem cells closer to intact status. Interestingly, the dramatic changes of nucleotide extended to non-target genes as well as target genes. Conclusions: Thus, hsa-miR-520d-5p is useful for studying hair or scalp conditioning and developing therapy against aging or hair diseases such as alopecia.

There are ample of research work on the detection of anomalies in the area of cyber security. However, only a few of them focus on physical access security. Physical access control, including employee and guest access and management system, supervised doors or location, surveillance camera, are critical checkpoints of a premise in terms of security monitoring. Breaches of these checkpoints can cause serious damage, where an insider or an outsider (e.g. through social engineering) may gain access to sensitive areas of the premise and may further result in data leakage or disruptions of services. In this paper, we characterise users based on their physical movement behavior and job profile in order to identify users with anomalous physical access behaviour using an unsupervised machine learning algorithm known as the Two Step clustering method. We further evaluate the type of risk posed by these users by comparing the user's behaviour with its peer group and observing a set of rule-based metrics. The framework is then being compared with other recent approaches for anomaly detection of physical access logs. Lastly, this framework is deployed in a real-world environment and successfully assisted in the detection of anomalous physical access behaviour.

The EVEREST II trial showed that for patients with polypoidal choroidal vasculopathy (PCV), intravitreal ranibizumab in combination with verteporfin photodynamic therapy improves visual acuity relative to ranibizumab monotherapy. However, whether combination therapy is incrementally cost-effective relative to monotherapy during a lifetime is unclear. To assess the incremental cost-effectiveness of combination therapy compared with ranibizumab monotherapy in patients with PCV. This model-based, economic evaluation used 2018 unit cost data from a tertiary eye hospital in Singapore, first- and second-year outcomes and resource use data from a multicenter trial across various Asian countries (EVEREST II) to model a hypothetical cohort of patients with symptomatic PCV. Scenario analyses and deterministic and probabilistic sensitivity analyses were performed to examine uncertainty. Data were collected from October 2018 through April 2019 and analyzed from March through October 2019. This model used data from the EVEREST II trial, in which all participants were given 0.5 mg of intravitreal ranibizumab once every 4 weeks for the first 3 months. Subsequent administration occurred as needed. For participants receiving combination therapy, standard fluence (50 J/cm3) photodynamic therapy with 6-mg/m2 verteporfin was administered once during the first 3 months and thereafter as needed. Incremental cost per quality-adjusted life-year (QALY) gained for combination therapy relative to monotherapy for patients with PCV. In this model based on a cohort of 1000 patients aged 68 years, a patient with PCV incurred a total cost in Singapore dollars (SGD) of 92 327 (US $67 399) with combination therapy and SGD 92 371 (US $67 431) with monotherapy during a lifetime horizon, generating a modest cost savings of SGD 44 (US $32) per patient undergoing combination therapy. Lifetime QALYs were estimated to be 7.87 for combination therapy and 7.85 for monotherapy, for an incremental gain of 0.02 QALYs. Combination therapy remained cost-saving or cost-effective in all lifetime scenarios modeled, but during shorter time horizons and at lower monotherapy costs, it may not be cost-effective. This study found combination therapy to be a dominant (more effective and less costly) strategy, being similar in costs and slightly more effective than ranibizumab monotherapy during a lifetime horizon. However, decreasing the time horizon to less than 10 years and/or reductions in the cost of monotherapy may result in combination therapy no longer being cost-effective.

The ability of DENV2 to display different morphologies (hence different antigenic properties) complicates vaccine and therapeutics development. Previous studies showed most strains of laboratory adapted DENV2 particles changed from smooth to “bumpy” surfaced morphology when the temperature is switched from 29°C at 37°C. Here we identified five envelope (E) protein residues different between two alternative passage history DENV2 NGC strains exhibiting smooth or bumpy surface morphologies. Several mutations performed on the smooth DENV2 infectious clone destabilized the surface, as observed by cryoEM. Molecular dynamics simulations demonstrated how chemically subtle substitution at various positions destabilized dimeric interactions between E proteins. In contrast, three out of four DENV2 clinical isolates showed a smooth surface morphology at 37°C, and only at high fever temperature (40°C) did they become “bumpy”. These results imply vaccines should contain particles representing both morphologies. For prophylactic and therapeutic treatments, this study also informs on which types of antibodies should be used at different stages of an infection, i.e., those that bind to monomeric E proteins on the bumpy surface or across multiple E proteins on the smooth surfaced virus.
