Blagden SP, Yu L-M, Ellis S, et al., 2022, Additional consensus recommendations for conducting complex innovative trials of oncology agents: a post-pandemic perspective, British Journal of Cancer, ISSN: 0007-0920
In our 2020 consensus paper, we devised ten recommendations for conducting Complex Innovative Design (CID) trials to evaluate cancer drugs. Within weeks of its publication, the UK was hit by the first wave of the SARS-CoV-2 pandemic. Large CID trials were prioritised to compare the efficacy of new and repurposed COVID-19 treatments and inform regulatory decisions. The unusual circumstances of the pandemic meant studies such as RECOVERY were opened almost immediately and recruited record numbers of participants. However, trial teams were required to make concessions and adaptations to these studies to ensure recruitment was rapid and broad. As these are relevant to cancer trials that enrol patients with similar risk factors, we have added three new recommendations to our original ten: employing pragmatism such as using focused information sheets and collection of only the most relevant data; minimising negative environmental impacts with paperless systems; and using direct-to-patient communication methods to improve uptake. These recommendations can be applied to all oncology CID trials to improve their inclusivity, uptake and efficiency. Above all, the success of CID studies during the COVID-19 pandemic underscores their efficacy as tools for rapid treatment evaluation.

Chiang RS, Desai A, Glover MJ, et al., 2022, Racial diversity and reporting in United States Food and Drug Administration registration trials for thoracic malignancies from 2006-2020, Cancer Investigation, Pages: 1-6, ISSN: 0735-7907
There is significant racial disparity in thoracic malignancies in terms of epidemiology and outcomes. We analyzed race reporting and racial diversity in the registration trials of drugs approved by the FDA for thoracic malignancies from 2006-2020. We found a significant under-representation of non-white participants in FDA drug registration trials in thoracic malignancies. Furthermore, though almost all trials report some race information, FDA guidelines are not universally followed. There is a disproportionate disease burden of lung cancer in under-represented race communities, and clinical trials should prioritize racial diversity and inclusion efforts.

Lythgoe MP, Prasad V, 2022, Repositioning canakinumab for non-small cell lung cancer-important lessons for drug repurposing in oncology, British Journal of Cancer, Vol: 127, Pages: 785-787, ISSN: 0007-0920
Canakinumab is an anti-interleukin-1β monoclonal antibody approved for use in a range of immune-related disorders. During the clinical investigation (CANTOS trial) for prevention of cardiovascular complications, therapy was linked to a reduction in both the occurrence and mortality of lung cancer. This unexpected observation fuelled the rapid initiation of four large clinical trials to evaluate potential anticancer efficacy (in combination with chemotherapy and/or immunotherapy), before fully validating these observations in a dedicated study. The first two trials (CANOPY-1 and 2) have now been reported and have both have failed to meet their primary efficacy endpoints. In this article, we explore the scientific and clinical rationale behind the development of canakinumab in oncology, the repurposing approach utilised and implications this may have for the wider drug repurposing field in the development of new cancer medicines.
Lythgoe MP, Mullish BH, Frampton A, et al., 2022, Polymorphic microbes: a new emerging hallmark of cancer, Trends in Microbiology, ISSN: 0966-842X
Recognition of the microbiome (and ‘polymorphic microbes’ within them) as a new emerging hallmark of cancer reflects a wide body of rapidly evolving research. Microbes may be directly carcinogenic, impact host immune responses to promote malignancy, and key effectors in determining anti-cancer therapy efficacy. Manipulation of the microbiome is showing promise as an opportunity to influence cancer outcomes.
Mirón-Barroso S, Correia JS, Frampton AE, et al., 2022, Polymeric carriers for delivery of RNA cancer therapeutics, Non-Coding RNA, Vol: 8, Pages: 58-58, ISSN: 2311-553X
As research uncovers the underpinnings of cancer biology, new targeted therapies have been developed. Many of these therapies are small molecules, such as kinase inhibitors, that target specific proteins; however, only 1% of the genome encodes for proteins and only a subset of these proteins has ‘druggable’ active binding sites. In recent decades, RNA therapeutics have gained popularity due to their ability to affect targets that small molecules cannot. Additionally, they can be manufactured more rapidly and cost-effectively than small molecules or recombinant proteins. RNA therapeutics can be synthesised chemically and altered quickly, which can enable a more personalised approach to cancer treatment. Even though a wide range of RNA therapeutics are being developed for various indications in the oncology setting, none has reached the clinic to date. One of the main reasons for this is attributed to the lack of safe and effective delivery systems for this type of therapeutic. This review focuses on current strategies to overcome these challenges and enable the clinical utility of these novel therapeutic agents in the cancer clinic.

Lythgoe M, Desai A, Gyawali B, et al., 2022, Cancer therapy approval timings, review speed and publication of pivotal registration trials in the US and Europe from 2010-2019, Jama Network Open, Vol: 5, ISSN: 2574-3805
Importance: Ensuring patients have access to safe and efficacious medicines in a timely manner is an essential goal for regulatory agencies, which has particular significance in oncology due to the significant unmet need for new therapies. The two largest regulatory agencies, the FDA and EMA have pivotal global roles, and their recommendations and approvals are frequently followed by other national regulators.Objective: To compare market authorization dates for new oncology therapies approved in the US and Europe over the past decade and to examine and contrast the regulatory activities of the FDA and EMA in the approval of new cancer medicines.Design, Setting and Participants: A review of the FDA and EMA regulatory databases to identify new oncology therapies approved in both the US and Europe from 2010 to 2019, and characterization of the timings of regulatory activities. Main Outcome Measures: Regulatory approval date, review time, submission of market authorization application, accelerated approval or conditional marketing authorisation status and proportion of approvals prior to peer-reviewed publication of pivotal trial results. Results: In total, 89 new concomitant oncology therapies were approved in the US and Europe from 2010 to 2019. The FDA approved 85 (95%) oncology therapies before European authorization and 4 (5%) therapies after. The median delay in market authorization for new oncology therapies in Europe was 241 days compared to the US. The median review time was 200 days and 426 days for the FDA and EMA, respectively. 60 (67%) new licensing applications were submitted to the FDA first, compared to 25 (28%) to the EMA. 35 (39%) oncology therapies were approved by the FDA prior to pivotal study publication, whereas only 8 (9%) by the EMA.Conclusion and Relevance: In this study we demonstrate that new oncology therapies are approved earlier in the US than Europe. The FDA receives licensing applications sooner and has shorter review times. However, mor

Benjamin DJ, Xu A, Lythgoe MP, et al., 2022, Cancer drug approvals that displaced existing standard-of-care therapies, 2016-2021, Jama Network Open, Vol: 5, Pages: 1-9, ISSN: 2574-3805
Importance Although several cancer drugs receive US Food and Drug Administration (FDA) approval each month, it is unclear how many of these cancer drugs transform the treatment landscape significantly by tumor group. Specifically, it remains unclear how many of these newly approved cancer drugs displace the existing standard-of-care therapies for their indication vs being added to existing therapies.Objective To examine how many cancer drugs displace the standard-of-care therapies vs being added to existing therapy or filling breaks in systemic treatments in the metastatic setting, adjuvant setting, or maintenance setting.Design, Setting, and Participants Retrospective cross-sectional study using landmark trials leading to FDA approval of cancer drugs between May 1, 2016, and May 31, 2021. The study evaluated all FDA approvals for cancer drugs between May 1, 2016, and May 31, 2021, using the FDA Oncology (Cancer)/Hematologic Malignancies Approval Notifications website. All clinical trials leading to FDA approval of cancer drugs during this period were examined.Main Outcomes and Measures A drug was determined to have displaced the prior standard-of-care therapy by evaluating the comparator arm (or lack thereof) in the clinical trial leading to the drug’s approval and also by reviewing National Comprehensive Cancer Network Guidelines. Cancer drug approvals were categorized as first-line displacing if a drug was approved for use in the first-line setting and displaced the prior standard-of-care drug for an indication, first-line drug alternatives/new if a drug was approved for use in the first-line setting but did not displace the standard of care at the time of approval or was a new drug that was first of its class for an approved indication, add on if a drug was approved in combination with a previously approved therapy for a disease or if a drug was approved for use in the adjuvant or maintenance settings, and later line if a drug was approved for use in t

Benjamin DJ, Lythgoe M, Raymakers AJN, et al., 2022, Cost effectiveness of newly approved second/third-line agents in metastatic urothelial carcinoma (mUC)., Journal of Clinical Oncology, Vol: 40, Pages: 574-574, ISSN: 0732-183X
<jats:p> 574 </jats:p><jats:p> Background: Over the past years, the treatment landscape of platinum-refractory mUC has drastically changed with the advent of immunotherapy. More recently, several new agents including enfortumab, erdafitinib, and sacituzumab have received F.D.A. approval for the treatment of platinum-refractory mUC. It is unclear if these newly approved therapies may be cost prohibitive for patients and/or hospitals/clinics compared to the recommended NCCN category 1 second-line agent, pembrolizumab. Methods: Using acquisition costs from our home institution’s cancer center pharmacy department, we calculated the total cost of treatment for each agent. We used phase II clinical trial data to determine the median duration of treatment for each therapy. For weight-based therapies, we used 70 kg as the weight for an average human adult. Results: The three newly approved therapies for mUC have total acquisition costs in descending order as follows: enfortumab vedotin ($153,697.50), edafitinib ($131,642.62), and sacituzumab govitecan ($63,198.07). Enfortumab and sacituzumab likely have higher total costs given both therapies require infusion center use for administration, and are associated with infusion center administration fees. In comparison, pembrolizumab (standard of care per NCCN guidelines) has a total acquisition cost of $51,343.60. Conclusions: Based off median duration of treatment, pembrolizumab has the lowest total acquisition cost compared to the three newly approved therapies for mUC. Further statistical analysis of this data set is ongoing. In particular, analysis will include out-of-pocket costs for patients as well as quality-adjusted life years (QALY).[Table: see text] </jats:p>

Haslam A, Lythgoe MP, Greenstreet Akman E, et al., 2021, Characteristics of Cost-effectiveness Studies for Oncology Drugs Approved in the United States From 2015-2020., JAMA Netw Open, Vol: 4
IMPORTANCE: Increasingly, cost-effectiveness analyses are being done to determine the value of rapidly increasing oncology drugs; however, this assumes that these analyses are unbiased. OBJECTIVE: To analyze the characteristics of cost-effectiveness studies and to determine characteristics associated with whether an oncology drug is found to be cost-effective. DESIGN, SETTING, AND PARTICIPANTS: This retrospective cross-sectional study included 254 cost-effectiveness analyses for 116 oncology drugs that were approved by the US Food and Drug Administration from 2015 to 2020. EXPOSURES: Each drug was analyzed for the incremental cost-effectiveness ratio per quality-adjusted life year, the funding of the study, the authors' conflict of interest, the threshold of willingness-to-pay, from what country's perspective the analysis was done, and whether a National Institute for Health and Care Excellence cost-effectiveness analysis had been done. MAIN OUTCOMES AND MEASURES: The main outcome was the odds of a study concluding that a drug was cost-effective. RESULTS: There were 116 drug approvals with 254 studies and country perspectives. Of the country perspectives, 132 (52%) were from the US. Forty-seven of 78 drugs with cost-effective studies had been shown to improve overall survival, whereas 15 of 38 of drugs without a cost-effectiveness study had been shown to improve overall survival. Having a study funded by a pharmaceutical company was associated with higher odds of a study concluding that a drug was cost-effective than studies without funding (odds ratio, 41.36; 95% CI, 11.86-262.23). CONCLUSIONS AND RELEVANCE: In this cross-sectional study, pharmaceutical funding was associated with greater odds that an oncology drug would be found to be cost-effective. These findings suggest that simply disclosing potential conflict of interest is inadequate. We encourage cost-effectiveness analyses by independent groups.

Background: Coronavirus Disease 2019 (COVID-19) continues to pose a significant healthcare challenge throughout the world. Co-morbidities including diabetes and hypertension are associated with a significantly higher mortality risk. However, the effect of cirrhosis on COVID-19 outcomes has yet to be systematically assessed.Objectives: To assess the reported clinical outcomes of patients with cirrhosis who develop COVID-19 infectionDesign/Method: Pubmed and Embase databases were searched for studies included up to 3rd February 2021. All English language primary research articles that reported clinical outcomes in patients with cirrhosis and COVID-19 were included. The study was conducted and reported in accordance with the PRISMA guidelines. Risk of bias was assessed using the QUIPS risk of bias assessment instrument for prognostic factor studies template. Meta-analysis was performed using Cochrane Revman 5.4 software using a random effects model.Results: 63 studies were identified reporting clinical outcomes in patients with cirrhosis and concomitant COVID-19. Meta-analysis of cohort studies which report a non-cirrhotic comparator yielded a pooled mortality odds ratio (OR) of 2.48 (95% CI 2.02 – 3.04). Analysis of a subgroup of studies reporting OR for mortality in hospitalised patients adjusted for significant confounders found a pooled adjusted OR 1.81 (CI 1.36-2.42).Conclusion: Cirrhosis is associated with an increased risk of all cause mortality in COVID-19 infection compared to non-cirrhotic patients. Patients with cirrhosis should be considered for targeted public health interventions to prevent COVID-19 infection such as shielding and prioritisation of vaccination.
