Objective: Behçet's disease (BD) is a systemic vasculitis with inflammatory lesions mediated by cytotoxic T cells and neutrophils. Apremilast, an orally available small‐molecule drug that selectively inhibits phosphodiesterase 4 (PDE4), has been recently approved for the treatment of BD. We aimed to investigate the effect of PDE4 inhibition on neutrophil activation in BD. Methods: We studied surface markers and reactive oxygen species (ROS) production by flow cytometry, and neutrophil extracellular traps (NETs) production and molecular signature of neutrophils by transcriptome analysis before and after PDE4 inhibition. Results: Activation surface markers (CD64, CD66b, CD11b, and CD11c), ROS production, and NETosis were up‐regulated in BD patient neutrophils compared to healthy donor neutrophils. Transcriptome analysis revealed 1,021 significantly dysregulated neutrophil genes between BD patients and healthy donors. Among dysregulated genes, we found a substantial enrichment for pathways linked to innate immunity, intracellular signaling, and chemotaxis in BD. Skin lesions of BD patients showed increased infiltration of neutrophils that colocalized with PDE4. Inhibition of PDE4 by apremilast strongly inhibited neutrophil surface activation markers as well as ROS production, NETosis, and genes and pathways related to innate immunity, intracellular signaling, and chemotaxis. Conclusion: We highlight key biologic effects of apremilast on neutrophils in BD. [ABSTRACT FROM AUTHOR]

Background: Although expanded access is an increasingly used pathway for patients to access investigational medicine, little is known on the magnitude and content of published scientific research collected via expanded access. Methods: We performed a review of all peer-reviewed expanded access publications between January 1, 2000 and January 1, 2022. We analyzed the publications for drugs, diseases, disease area, patient numbers, time, geographical location, subject, and research methodology (single center/multicenter, international/national, prospective/retrospective). We additionally analyzed endpoints reported in all COVID-19-related expanded access publications. Results: We screened 3810 articles and included 1231, describing 523 drugs for 354 diseases for 507,481 patients. The number of publications significantly increased over time ( p < 0.001 ). Large geographical disparities existed as Europe and the Americas accounted for 87.4% of all publications, whereas Africa only accounted for 0.6%. Oncology and hematology accounted for 53% of all publications. Twenty-nine percent of all expanded access patients (N = 197,187) reported on in 2020 and 2021 were treated in the context of COVID-19. Conclusions: By summarizing characteristics of patients, diseases, and research methods described in all scientific literature published on expanded access, we provide a unique dataset for future research. We show that published scientific research on expanded access has surged over the past decades, partly due to COVID-19. However, international collaboration and equity in geographic access remain an issue of concern. Lastly, we stress the need for harmonization of research legislation and guidance on the value of expanded access data within real-world data frameworks to improve equity in patient access and streamline future expanded access research.

Regulatory decisions on paediatric investigation plans (PIPs) aim at making effective and safe medicines timely available for children with high unmet medical need. At the same time, scientific knowledge progresses continuously leading frequently to the identification of new molecular targets in the therapeutic area of oncology. This, together with further efforts to optimise next generation medicines, results in novel innovative products in development pipelines. In the context of global regulatory development requirements for these growing pipelines of innovative products (e.g. US RACE for children Act), it is an increasing challenge to complete development efforts in paediatric oncology, a therapeutic area of rare and life-threatening diseases with high unmet needs. Regulators recognise feasibility challenges of the regulatory obligations in this context. Here, we explain the EU regulatory decision making strategy applied to paediatric oncology, which aims fostering evidence generation to support developments based on needs and robust science. Because there is a plethora of products under development within given classes of or within cancer types, priorities need to be identified and updated as evidence evolves. This also includes identifying the need for third or fourth generation products to secure focused and accelerated drug development. An agreed PIP, as a plan, is a living document which can be modified in light of new evidence. For this to be successful, input from the various relevant stakeholders, i.e. patients/parents, clinicians and investigators is required. To efficiently obtain this input, the EMA is co-organising with ACCELERATE oncology stakeholder engagement platform meetings. • Regulatory decision-making in the context of product development life cycle. • PIP as a plan, allowing for evidence generation, able to be modified. • Fostering collaborative development environment, not competitive. • Need to identify priorities based on science. • Collaboration among all stakeholders key, as exemplified by ACCELERATE.

The eighth Paediatric Strategy Forum focused on multi-targeted kinase inhibitors (mTKIs) in osteosarcoma and Ewing sarcoma. The development of curative, innovative products in these tumours is a high priority and addresses unmet needs in children, adolescents and adults. Despite clinical and investigational use of mTKIs, efficacy in patients with bone tumours has not been definitively demonstrated. Randomised studies, currently being planned or in progress, in front-line and relapse settings will inform the further development of this class of product. It is crucial that these are rapidly initiated to generate robust data to support international collaborative efforts. The experience to date has generally indicated that the safety profile of mTKIs as monotherapy, and in combination with chemotherapy or other targeted therapy, is consistent with that of adults and that toxicity is manageable. Increasing understanding of relevant predictive biomarkers and tumour biology is absolutely critical to further develop this class of products. Biospecimen samples for correlative studies and biomarker development should be shared, and a joint academic-industry consortium created. This would result in an integrated collection of serial tumour tissues and a systematic retrospective and prospective analyses of these samples to ensure robust assessment of biologic effect of mTKIs. To support access for children to benefit from these novel therapies, clinical trials should be designed with sufficient scientific rationale to support regulatory and payer requirements. To achieve this, early dialogue between academia, industry, regulators, and patient advocates is essential. Evaluating feasibility of combination strategies and then undertaking a randomised trial in the same protocol accelerates drug development. Where possible, clinical trials and development should include children, adolescents, and adults less than 40 years. To respond to emerging science, in approximately 12 months, a multi-stakeholder group will meet and review available data to determine future directions and priorities. • mTKIs are being evaluated in osteosarcoma and Ewing sarcoma. • Ongoing or planned randomised studies will inform further development. • Toxicity is tolerable when mTKIs are combined with chemotherapy. • Increased understanding of predictive biomarkers and tumour biology is crucial. • A joint academic-industry consortium should share and analyse biomarker samples.

Options for the effective treatment of hereditary optic neuropathies have been a long time coming. The successful launch of the antioxidant idebenone for Leber's Hereditary Optic Neuropathy (LHON), followed by its introduction into clinical practice across Europe, was an important step forward. Nevertheless, other options, especially for a variety of mitochondrial optic neuropathies such as dominant optic atrophy (DOA), are needed, and a number of pharmaceutical agents, acting on different molecular pathways, are currently under development. These include gene therapy, which has reached Phase III development for LHON, but is expected to be developed also for DOA, whilst most of the other agents (other antioxidants, anti-apoptotic drugs, activators of mitobiogenesis, etc.) are almost all at Phase II or at preclinical stage of research. Here, we review proposed target mechanisms, preclinical evidence, available clinical trials with primary endpoints and results, of a wide range of tested molecules, to give an overview of the field, also providing the landscape of future scenarios, including gene therapy, gene editing, and reproductive options to prevent transmission of mitochondrial DNA mutations.

Only one class of targeted agents (anti-GD2 antibodies) has been incorporated into front-line therapy for neuroblastoma since the 1980s. The Neuroblastoma New Drug Development Strategy (NDDS) initiative commenced in 2012 to accelerate the development of new drugs for neuroblastoma. Advances have occurred, with eight of nine high-priority targets being evaluated in paediatric trials including anaplastic lymphoma kinase inhibitors being investigated in front-line, but significant challenges remain. This article reports the conclusions of the second NDDS forum, which expanded across the Atlantic to further develop the initiative. Pre-clinical and clinical data for 40 genetic targets and mechanisms of action were prioritised and drugs were identified for early-phase trials. Strategies to develop drugs targeting TERT, telomere maintenance, ATRX, alternative lengthening of telomeres (ALT), BRIP1 and RRM2 as well as direct targeting of MYCN are high priority and should be championed for drug discovery. Promising pre-clinical data suggest that targeting of ALT by ATM or PARP inhibition may be potential strategies. Drugs targeting CDK2/9, CDK7, ATR and telomere maintenance should enter paediatric clinical development rapidly. Optimising the response to anti-GD2 by combinations with chemotherapy, targeted agents and other immunological targets are crucial. Delivering this strategy in the face of small patient cohorts, genomically defined subpopulations and a large number of permutations of combination trials, demands even greater international collaboration. In conclusion, the NDDS provides an internationally agreed, biologically driven selection of prioritised genetic targets and drugs. Improvements in the strategy for conducting trials in neuroblastoma will accelerate bringing these new drugs more rapidly to front-line therapy. • The Neuroblastoma New Drug Development Strategy initiative aims to accelerate new drugs development. •Twenty two of 40 targets were identified as high priority for neuroblastoma. •Targeting telomere maintenance, ATRX , BRIP1 , RRM2 are high priority for drug discovery. •Drugs targeting CDK2/9, CDK7, ATR should enter paediatric clinical development rapidly. •Combining targeted therapies with immunological agents is crucial.

Janus kinase (JAK) is a signal transducer and activator of a protein transcription system that transduces signals from cell surface cytokine and growth factor receptors to the nucleus. Recently developed JAK inhibitors (JAKinibs) inhibit JAKs non-selectively or selectively and down-regulate the effects of corresponding ligands (i.e. cytokines and growth factors). JAKinibs are efficacious against rheumatoid arthritis and other immune-mediated inflammatory diseases and are being increasingly prescribed clinically. Regarding safety, JAKinib use is associated with common or unique changes in laboratory parameters; however, incidence rates of serious adverse drug reactions (ADRs) associated with these changes are low. Opportunistic and other infections, including tuberculosis, are the most critical ADRs of treatment with JAKinibs, and screening and monitoring of patients should be carefully performed. Incidence rates of herpes zoster (HZ) in patients receiving JAKinibs are high in Japan and Korea, and modestly high in other countries. Filgotinib may not be associated with an elevated risk for HZ, but long-term safety data are lacking. Data from clinical development programmes and post-marketing surveillance have indicated no increased risk for malignancy or serious cardiac events; however, long-term observational studies are necessary. Despite the non-elevated risk of gastrointestinal perforations, patients with older age and/or a history of diverticulitis or receiving non-steroidal anti-inflammatory drugs should be carefully evaluated to determine the risk-benefit balance. The incidence rates of venous thromboembolism with all approved doses are similar to that expected in the population, although there are discrepancies in the placebo-controlled portion of the baricitinib clinical development programmes. Regulatory agencies in the USA and Europe suggested a higher risk for thrombotic events in patients receiving JAKinibs. Pharmacokinetic studies demonstrated that dose adjustment should be considered for JAKinib use in patients with moderate-to-severe renal or hepatic dysfunction, depending on the metabolism of each drug. Long-term observational studies enrolling patients with diverse clinical backgrounds are required to strike a risk-benefit balance in clinical settings. [ABSTRACT FROM AUTHOR]

Curative therapies and other medicines considered "game-changing" in terms of health gain can be accompanied by high demand and high list prices that pose budget challenges to public and private payers and health systems-the so-called affordability issue. These challenges are exacerbated when longer term effectiveness, and thus value for money, is uncertain, but they can arise even when treatments are proven to be highly cost-effective at the time of launch. This commentary reviews innovative payment solutions proposed in the literature to address the affordability issue, including the use of credit markets and of staged payments linked to patient outcomes, and draws on discussions with payers in the United States and Europe on the feasibility or desirability of operationalizing any of the alternative financing and payment strategies that appear in the literature. This included a small number of semistructured interviews. We conclude that there is a mismatch between the enthusiasm in the academic literature for developing new approaches and the scepticism of payers that they can work or are necessary. For the foreseeable future, affordability pressures will continue to be handled by aggressive price bargaining, high co-pays (in systems in which this is possible), and restricting access to subgroups of patients. Of the mechanisms we explored, outcomes-based payments were of most interest to payers, but the costs associated with operating such schemes, together with implementation challenges, did not make them an attractive option for managing affordability.

In this article, we consider the new drugs approved for the European market in 2015. We present a summary of the new mechanisms of action introduced and highlight three new mechanisms of action with a potentially high future impact: PCSK9 inhibition (alirocumab (Praluent®) and evolocumab (Repatha®)) for hypercholesterolaemia, neprilysin inhibition (sacubitril in combination with valsartan (Entresto®)) for heart failure, and interleukin-5 inhibition (mepolizumab (Nucala®)) for asthma.

Background: Venous thromboembolism (VTE) is a major health problem, with over one million events every year in Europe. However, there is a paucity of data on the current management in real life, including factors influencing treatment pathways, patient satisfaction, quality of life (QoL), and utilization of health care resources and the corresponding costs. The PREFER in VTE registry has been designed to address this and to understand medical care and needs as well as potential gaps for improvement. Methods/design: The PREFER in VTE registry was a prospective, observational, multicenter study conducted in seven European countries including Austria, France Germany, Italy, Spain, Switzerland, and the UK to assess the characteristics and the management of patients with VTE, the use of health care resources, and to provide data to estimate the costs for 12 months treatment following a first-time and/or recurrent VTE diagnosed in hospitals or specialized or primary care centers. In addition, existing anticoagulant treatment patterns, patient pathways, clinical outcomes, treatment satisfaction, and health related QoL were documented. The centers were chosen to reflect the care environment in which patients with VTE are managed in each of the participating countries. Patients were eligible to be enrolled into the registry if they were at least 18 years old, had a symptomatic, objectively confirmed first time or recurrent acute VTE defined as either distal or proximal deep vein thrombosis, pulmonary embolism or both. After the baseline visit at the time of the acute VTE event, further follow-up documentations occurred at 1, 3, 6 and 12 months. Follow-up data was collected by either routinely scheduled visits or by telephone calls. Results: Overall, 381 centers participated, which enrolled 3,545 patients during an observational period of 1 year. Conclusion: The PREFER in VTE registry will provide valuable insights into the characteristics of patients with VTE and their acute and mid-term management, as well as into drug utilization and the use of health care resources in acute first-time and/or recurrent VTE across Europe in clinical practice.

Purpose: The aim of this study is to provide a comprehensive overview of the outcomes of marketing authorisation applications via the mutual recognition and decentralised procedures (MRP/DCP) and assess determinants of licensing failure during CMDh referral procedures. Methods: All MRP/DCP procedures to the Co-ordination group for Mutual recognition and Decentralised procedures-human (CMDh) during the period from January 2006 to December 2013 were analysed. Reasons for starting referral procedures were scored. In addition, a survey under pharmaceutical companies was performed to estimate the frequency of licensing failure prior to CMDh referrals. Results: During the study period, 10392 MRP/DCP procedures were finalized. Three hundred seventy-seven (3.6 %) resulted in a referral procedure, of which 70 (19 %) resulted in licensing failure, defined as refusal or withdrawal of the application. The frequency of CMDh referrals decreased from 14.5 % in 2006 to 1.6 % in 2013. Of all referrals, 272 (72 %) were resolved through consensus within the CMDh, the remaining 105 (28 %) were resolved at the level of the CHMP. Most referrals were started because of objections raised about the clinical development program. Study design issues and objections about the demonstration of equivalence were most likely to result in licensing failure. An estimated 11 % of all MRP/DCP procedures resulted in licensing failure prior to CMDh referral. Conclusion: Whereas the absolute number of MRP/DCP procedures resulting in a referral has reduced substantially over the past years, no specific time trend could be observed regarding the frequency of referrals resulting in licensing failure. Increased knowledge at the level of companies and regulators has reduced the frequency of late-stage failure of marketing applications via the MRP/DCP. [ABSTRACT FROM AUTHOR]

Regulatory agency interaction occurs from before a candidate drug enters clinical development and all the way to marketing approval and beyond. This paper presents ways to enable successful interaction by avoiding issues, with an emphasis on nonclinical testing aspects. Strategic thinking as to whether an early regulatory agency meeting should occur is discussed and if yes, how to make it a success by generating relevant questions with proper preparation including a robust Briefing Document. Examples of unfavourable regulatory agency feedback during meetings is given which may have been avoided. Similarly, ways for successful regulatory submission in the form of a Clinical Trials Application (CTA) in Europe or an Investigational New Drug (IND) application in the US are considered with examples of comments that can be received from regulatory agencies. At marketing application stage with submission of a Marketing Authorisation Application (MAA) in Europe and a New Drug Application (NDA) or a Biologic License Application (BLA) in the US, a key document is the Nonclinical Overview and suggested content and potential deficiencies are presented to allow avoidance of adverse regulatory agency responses and time delay. Successful regulatory agency interaction involves robust scientific thinking, proper planning and well-written documentation. • Ways to enable successful nonclinical regulatory agency interaction were examined. • For regulatory agency meetings, relevant questions and proper preparation are vital. • Ways to ensure robust clinical trial and product licence documents are discussed. • Overall, robust scientific thinking, proper planning and well-written documentation are key.

Simple Summary: This opinion paper describes the regulatory hurdles for a clinical oncologist and physician scientist to activate an Investigator-Initiated Trial (IIT) before and after 2004 with German regulation as an example. Changes in legal framework with impacts on time and costs to activate a clinical trial are described. Evidence needed to reach the objective of higher patient safety and trial quality by European Union (EU) Clinical Trial Directive (CTD) 2001/20 is discussed. Shortly after the beginning of the year 2000, multiple legal changes with impacts on the regulatory framework of clinical trials became effective almost simultaneously. They included the European Union (EU) Clinical Trial Directive (CTD) 2001/20 followed by major changes in national drug laws, the change in the legal status of German University Hospitals (1998), and a new disease-related groups (DRG)-based reimbursement system for hospitals in Germany (2000). Together, these changes created enormous bureaucratic and financial inhibition of activation and conduct of academic investigator-initiated clinical trials (IIT). Examples for activating clinical trials in oncology before and after 2004 are outlined and discussed, focussing on extended time frames, the establishment of centralized responsibility structures and the exploding financial consequences. In addition, the evolution of trial numbers and the distribution of trial initiators between "commercial" and "academic" over time are discussed together with the occurrence of clinical registries. At the same time, progress in molecular biology led to a plethora of new targets for effective pharmacological therapy of life-threatening diseases such as cancer, and the overall number of clinical trials has not decreased. Yet, judging the regulatory and administrative hurdles between scientific study design and first-patient on trial before and after 2004 and weighing these against the lack of evidence that this regulation has achieved its goal to enhance patient safety and trial quality, the necessity to completely overhaul this CTD becomes obvious. A main goal of such an initiative should be to minimize bureaucracy. For the specific situation in Germany, relocation of responsibility and freedom to operate in University Hospitals and Medical Faculties back to the physician–scientists and reduction in interference by legal divisions should be a goal as well as increasing the public financial support for IITs.

Summary: Background: Depletion of B lymphocytes is associated with suppression of inflammatory activity in multiple sclerosis. We aimed to assess the safety and efficacy of atacicept, a recombinant fusion protein that suppresses B-cell function and antibody production. Methods: In this placebo-controlled, double-blind, 36-week, phase 2 trial (ATAMS) in Australia, Canada, Europe, and the USA, patients aged 18–60 years with relapsing multiple sclerosis were randomly assigned via an interactive voice response system in a 1:1:1:1 ratio, stratified by geographical region, to receive weekly subcutaneous injections with atacicept (25, 75, or 150 mg) or placebo. Both patients and study personnel were masked to treatment assignment. The primary endpoint was the change in mean number of gadolinium-enhancing lesions on T1-weighted MRI per patient per scan between weeks 12 and 36. Efficacy endpoints were analysed in the intention-to-treat population. Patients who completed week 36 were eligible to participate in a long-term extension study (ATAMS EXT), consisting of a double-blind phase followed by an open-label phase, for a total study time of up to 5 years. The study was terminated early after the independent data and safety monitoring board noted an increased annualised relapse rate with atacicept. The protocol was subsequently amended to include a 60-week safety follow-up, to allow treatment with approved multiple sclerosis drugs, and to change the primary endpoint to gadolinium-enhancing T1 lesions per scan during the entire double-blind period of ATAMS. Both the trial and the extension are registered with ClinicalTrials.gov, numbers NCT00642902 (ATAMS) and NCT00853762 (ATAMS EXT). Findings: Between April 23, 2008, and early study termination on Sept 11, 2009, 255 patients were randomly assigned: 63 to placebo, 63 to atacicept 25 mg, 64 to 75 mg, and 65 to 150 mg. 90 (35%) patients completed the week 36 treatment visit, 26 (10%) discontinued before study termination (including one who dropped out before receiving study treatment), and 139 (55%) discontinued because of study termination. During the double-blind period of ATAMS, annualised relapse rates were higher in the atacicept groups than in the placebo group (atacicept 25 mg, 0·86, 95% CI 0·43–1·74; 75 mg, 0·79, 0·40–1·58; 150 mg, 0·98, 0·52–1·81; placebo, 0·38, 0·17–0·87). Mean numbers of gadolinium-enhancing T1 lesions per scan were similar in all groups (25 mg, 2·26, 0·97–5·27; 75 mg, 2·30, 1·08–4·92; 150 mg, 2·49, 1·18–5·27; placebo, 3·07, 1·40–6·77). Seven patients (one taking placebo and six atacicept) discontinued treatment because of adverse events. One death occurred in the placebo group. During the safety follow-up, immunoglobulin concentrations and B-cell counts returned towards predose values and annualised relapse rates in the atacicept groups decreased until they were similar to that of the placebo group Interpretation: Increased clinical disease activity associated with atacicept suggests that the role of B cells and humoral immunity in multiple sclerosis is complex. For studies that explore therapeutic immunomodulation in multiple sclerosis, rigorous monitoring for negative effects on clinical and MRI outcomes is warranted.

ONO-5334, a selective inhibitor of cathepsin K, is a potential new treatment for osteoporosis. The objectives of this study were to (1) develop population pharmacokinetic-pharmacodynamic (PK-PD) models for ONO-5334 using dose-ascending data from healthy postmenopausal females, (2) examine comparability of PK and/or PD profile between Caucasian and Japanese, and (3) compare PK-PD profile between immediate release tablet (IRT) and sustained release tablet (SRT). The population PK-PD models were developed for each formulation for post-dose levels of bone resorption markers (serum CTX and NTX). The data were provided from 4 phase 1 studies with total of 201 Caucasian and 94 Japanese subjects. Plasma concentrations of ONO-5334 and bone resorption markers were thoroughly evaluated in those studies. An indirect response model described relationships between bone resorption markers and plasma concentrations of ONO-5334. There was no significant difference in PK and pharmacodynamic potency (IC50) between Caucasian and Japanese. Based on the developed model, serum CTX and NTX after administration of ONO-5334 IRT or SRT were simulated, and the results showed that ONO-5334 SRT would provide comparable PD effect on bone resorption markers with lower dose relative to IRT.

S-1 (Teysuno) is an oral anticancer agent comprising the 5-fluorouracil (5-FU) prodrug tegafur and targeted modulators, gimeracil and oteracil. S-1 in combination with cisplatin is a recommended first-line treatment for gastrointestinal cancers in Japan and has recently been approved in the EU for the treatment of advanced gastric cancer. This article reviews S-1 pharmacology from an EU perspective. In a randomized, open-label trial in 24 non-Asian countries in patients with advanced gastric cancer, there were no significant differences between S-1 plus cisplatin and 5-FU plus cisplatin groups in median overall survival (OS) [primary endpoint], progression-free survival or overall response rate. In a post hoc analysis of OS, S-1 plus cisplatin was noninferior to 5-FU plus cisplatin. There were no significant between-group differences in patient quality of life, according to the Functional Assessment of Cancer Therapy (Gastric) Trial Outcome Index, except that S-1 plus cisplatin recipients had a significantly longer time to worsening in physical well-being than 5-FU plus cisplatin recipients. Overall, S-1 plus cisplatin was better tolerated than 5-FU plus cisplatin, with significantly lower rates of haematological, some gastrointestinal tract and other adverse events, serious adverse events and deaths resulting from toxicity, along with significantly fewer haematological and renal function abnormalities. Compared with 5-FU, S-1 plus cisplatin recipients had significantly higher rates of hand-foot syndrome and hyperbilirubinaemia, although there were no between-group differences in the proportions of patients with increased liver enzymes. S-1 is a useful alternative to 5-FU for patients with advanced gastric cancer. [ABSTRACT FROM AUTHOR]

Drug development performance is examined using data on clinical research projects of 10 pharmaceutical companies. In contrast to previous work on the discovery phase of pharmaceutical R&D we find a strong correlation between the diversity of firms' development efforts and the success probability of individual projects, but no effect of scale per se. Large firms' superior performance in drug development appears to be driven by returns to scope rather than returns to scale. Scope is confounded with firm fixed effects, however, suggesting an important role for inter-firm differences in the organization and management of the development function. [ABSTRACT FROM AUTHOR]

Background. Many new cancer medicines have been developed that can improve patients' outcomes. However, access to these agents comes later in Europe than in the United States (US). The aim of this study is to assess the access in Europe to newly registered cancer drugs and to get more insight in the implications of these variations for patients. Methods. A retrospective database study was conducted. Analyses involved 12 cancer drugs and 28 European countries in the period 2011–2018. Time to patient access, speed of drug uptake, and the potential loss of life years due to a delay in access have been studied. Results. Marketing approval for the cancer drugs came on average 242 days later in Europe than in the US, and actual patient access varied extensively across Europe. The average time to market in Europe was 403 days (range 17–1187 days). The delay in patient access of ipilimumab and abiraterone may have led to a potential loss of more than 30,000 life years. Conclusion. It takes a long time for patients to get access to newly registered cancer drugs and there is great variation in access. The health outcomes can be substantially improved by faster processes. [ABSTRACT FROM AUTHOR]
