LIBERTY claim analysis manuscript by Thomas Wilke and Sabrina Mueller

September 22, 2020

Research Scientists, Thomas Wilke and Sabrina Mueller recently published a manuscript on “Diabetes-Related Effectiveness and Cost of Liraglutide or Insulin in German Patients with Type 2 Diabetes: A 5-Year Retrospective Claims Analysis”.

As insulin and liraglutide are both treatment options for type 2 diabetes mellitus (T2DM), it was important to understand their long-term real-world outcomes. A retrospective study was conducted using administrative claims from a German health fund (AOK PLUS) and clinical data; the clinical data was collected in a disease management program. This claims data analysis, in adult patients with T2DM, investigated diabetes-related effectiveness and costs with long-term (up to five years) treatment with liraglutide or any insulin, in a real-world setting.

New Audiobook on Synthetic Control Arms

September 16, 2020

Synthetic control arms (SCA) are virtual trial arms that use historical claims data and observational data to simulate the control arm of a study. When enrollment targets are low and large amounts of data already exist about the performance of a control, then in many cases using quantitative techniques to simulate a control arm of a trial will expedite timelines and serve as a more optimal use of resources.

Cytel’s new audiobook "Demystifying synthetic control arms", provides insights on synthetic controls, suitable conditions for their use, and some common quantitative strategies for trial design and regulatory submission. Click the button download the audiobook.

From Before to After: Preparing and Concluding your FDA Data Submission

September 14, 2020

“A good start is half the battle” (the Before) when submitting data to the FDA and there are a couple of cherries to put on top (the After) when your regulatory group has finally submitted the eCTD to the FDA[1] . A good start is to have early discussions with the agency by regularly meeting them and sharing the status of your clinical data standards. While, the cherry on the top is the continuous support you need to guarantee to your submission project to promptly react when the reviewers come back with questions and additional requests during the review process.

Does your Trial need a Synthetic Control Arm?

September 10, 2020

Single arm trials are emerging as an accepted way of assessing a new treatment intervention. They establish clinical benefit by demonstrating the positive effects of a new therapy or treatment, without the need to use placebo or standard of care as a control. Instead, alternative approaches of establishing the comparison are used; these have become known as external controls or synthetic control arms (SCA) and include approaches leveraging real world data from various sources or evaluations of historical clinical trial data.

Making the Most of Your Data II: Optimizing Clinical Information in Trial Design and Implementation Using Bayesian Methods

August 11, 2020

While there is increasing optimism about the discovery of a COVID-19 vaccine, one of the less talked about aspects of such vaccines development are the lessons that can be used in other therapeutic areas. After all, COVID-19 vaccines development has uncovered numerous ways to design and execute trials within shorter time-frames and with less data.

One theme that has emerged consistently is the need to optimize the use of clinical information available, an endeavor well-supported by Bayesian methods.

Making the Most of Your Observational Data: Creating a Synthetic Control from Your Natural History Study

August 7, 2020

Recently a biotech approached Cytel for support with a Phase 2 Study in oncology. Regulators had requested a natural history of disease study, which tracks disease progression in the absence of any form intervention. These studies are used to build disease-models that can then inform a range of development opportunities within a drug development program.

A March 2019 FDA Guidance highlighted the importance of such studies for rare diseases, with former FDA Director Scott Gottlieb acknowledging that a lack of knowledge about the natural history of certain diseases is a significant obstacle in rare disease drug development.

Head to Head Comparisons Using Real World Data – Design and Data Considerations from Cardiovascular Pilot Investigation

August 5, 2020

Cytel is conducting two pilot projects on head-to-head comparisons using real world data. These projects in oncology and cardiovascular will occur in real time and will take place across our latest webinar series on the topic. The aim of this series is to introduce our audience to head to head to comparison using Real World Data (RWD) while focusing on practical application and results from the pilot projects.

The second webinar from this series was held on July 28, 2020 and outlines the design of the cardiovascular pilot investigation. None of the existing randomized trials of recently developed second-line antihyperglycemic agents can provide adequate information on their comparative effectiveness and safety regarding cardiovascular outcomes. Conducting Target Trials to get information of interest would be costly, difficult to perform, and would take many years to complete. As a result, we need to use observational databases to emulate it. This blog provides a brief on the design of the cardiovascular pilot project. Our team of experts also discussed the data requirements and the data source to be used in the pilot investigation, with the primary challenge focusing on how to assess if data are sufficient for the purposes of trial emulation.

Therapeutic Area User Guidance – The hidden Gems

July 28, 2020

CDISC standards have been around for a while with the first SDTM Standard version released in 2004. However, it was only in the last decade that it became “The Standard”, particularly when Health Authorities (HA), such as the US FDA and Japanese PMDA, made it a requirement for data submissions to support most of the regulatory requests for market approval. Additionally, most of the Pharma companies made the CDISC standards a part of their operational data model and consequently, the number of studies using the CDISC standards increased across phases of development.

The benefit of receiving data in standard formats was soon recognized by HA reviewers as they now require lesser time to understand the structure of the data they receive. Integration of data provided by different sponsors, for example on the same indication, for better understanding of safety signals, has become possible with data submitted in standard CDISC format.

However, the HAs such as the US FDA, soon realized that this was not enough, for two main reasons:

  1. sponsors sometimes make bad or different interpretations of the standard
  2. lack of standards or use cases in specific disease areas or indication
The first issue has been addressed by a number of specific HA conformance technical guidance [1,2] and regular public webinars where the HAs presented to the Industry real examples of bad standards implementations [3]. For the second issue, it was soon clear that the gap to be fixed was bigger and required more investment and resources. The CDISC Therapeutic Area User Guidance (TAUGs) are an “attempt” to fill this gap and reduce interpretation, and misinterpretation, of the standards [4].

The Good Data Submission Doctor: CDISC for COVID-19

June 29, 2020

From the time the COVID-19 outbreak was declared a pandemic, the number of studies conducted around the world to either diagnose, prevent or treat the virus literally exploded (1570 as on today, according to the Cytel Global Coronavirus COVID-19 Clinical Trial Tracker1).

Moreover, the pandemic impacted the regular schedule of ongoing clinical trials. Health authorities such as the FDA, promptly provided recommendations in the form of questions and answers on how to handle “disruptions” due to the pandemic2. These disruptions include a range of challenges including skipped assessments or study withdrawal.

“CDISC launched a task force in an effort to support CDISC members and the research community as they work tirelessly to discover critical breakthroughs to treat COVID-19 …. The task force was launched with the goal of developing Interim User Guide and Related material” said David Bobbitt, CDISC CEO, in an interview with Outsourcing-Pharma.com3. On April 21, 2020, the task force released two guidances. In this blog, I provide you with a quick summary of what these guidances address.

One of the revelations of the COVID-19 pandemic is that the flexibility and potential of Bayesian designs goes far beyond the benefits connected to informed priors. Rather a number of other benefits to Bayesian designs are sometimes under-appreciated. The importance of using Bayesian methods to choose composite endpoints, for example, particularly in longitudinal studies, can be overlooked when considering Bayesian and Frequentist options.

Optimizing Patient Recruitment: Download Whitepaper

June 18, 2020

A number of trials recently disrupted by the COVID-19 pandemic are now in the process of re-assessing recruitment timelines, and establishing new recruitment targets. Recruitment projections, though, are only as good as the starting assumptions with which a forecast is made and the models subsequently used to calculate timelines.

Overly simplistic assumptions, even familiar ones like, “All patients will arrive and enroll in a strictly linear fashion,” have strong  drawbacks. In order to maximize the potential to achieve recruitment milestones and to avoid misleading trial projections, planning must take careful precautions even when conditions are not this uncertain.

Our second webinar from this series was held on June 3, 2020, with Professor Christopher Jennison. Professor Jennison spoke about the modern uses of Group Sequential Designs and Sample Size Re-estimation. Group Sequential Designs were one of the earliest deviations from a traditional two-arm clinical trial with no interim looks at the data. They still add amazing value to trials through their abilities to safeguard patients, reach positive conclusions early and keep trial designs simple and streamlined. Sample Size Re-estimation is another key tool in the modern trial designer’s toolkit.

Interview with Alind Gupta: Transparent Machine Learning in Oncology

April 20, 2020

Cytel is hosting a webinar on Transparent Machine Learning in Oncology, on April 21, 2020. Our speaker, Alind Gupta, Machine Learning specialist, will provide insights on a particular transparent ML method called Bayesian networks, and how we have been using it for HEOR and other real world applications in oncology trials. As the adoption of machine learning is on the rise, we speak to Alind about the differences between black-box models and transparent machine learning, and how the latter is becoming more important in clinical research today. Alind also speaks about the application of ML on real-world data and how it is going to evolve in the coming years.

Machine learning (ML) aims to discover patterns from data that can be used for prediction, but the use of “black-box” ML models in healthcare research and decision-making has been limited, due to clinical liability and lack of trust from stakeholders. FDA guidelines for ML-based devices mandate transparency to assure continual safety and efficiency as notable recent failures have prompted increasing ML research into bias, fairness and causality. This has ramifications for all therapeutic areas but particularly within oncology.

Remote Working Arrangement – How to get it right?

April 2, 2020

On March 16, the World Health Organization (WHO) Director-General, Dr. Tedros Adhanom Ghebreyesus, in his media briefing on COVID-19, described the coronavirus pandemic as “the defining global health crisis of our time"[1]. The pandemic has affected 176 countries and territories around the world. WHO is urging all governments to scale-up aggressive measures to combat COVID-19 as more cases and deaths are being reported across the globe. Until a vaccine is made available, social distancing is of the utmost importance to reduce transmission and enable health systems to cope.

The U.S. Centers for Disease Control and Prevention (CDC) defines social distancing as “remaining out of congregate settings, avoiding mass gatherings, and maintaining distance (approximately 6 feet or 2 meters) from others when possible” [2]. Governments in several countries have shut down public places such as parks, gyms, malls, schools, restaurants etc., for a minimum of 15 days, to be extended depending upon the situation.

In these circumstances, it is inevitable that companies worldwide also show solidarity by allowing their employees to work remotely, from the safety of their homes. In Seattle, the hub of many of America’s early COVID-19 cases, companies including Amazon, LinkedIn, Microsoft and Google advised workers to stop coming to office in late February [3]. With more employers taking this necessary and precautionary step, the question arises - how do we ensure that it is done right?

Interview with Jay Park: The present and future of Master Protocols

March 12, 2020

In September 2018, the FDA provided a draft guidance on master protocols reflecting an increased interest in these designs by industry. This came after a 2017 editorial published by the Drs. Woodcock and LaVange from the FDA in the New England Journal of Medicine. In this guidance master protocol is defined as a protocol designed with multiple substudies, which may have different objectives and involves coordinated efforts to evaluate one or more investigational drugs in one or more disease subtypes within the overall trial structure. As the adoption of these innovative trial methods is on the rise, we speak with Jay Park, Director, Cytel, about the concept of master protocols, their importance and future growth potential. We take a closer look at their use in oncology trials where the increase in biomarker driven enrichment and stratification designs, as well as the use of companion diagnostics, ensures that master protocols are often adopted by trial investigators.

Bayesian Methods for Contending with Homogeneity and Heterogeneity in Real World Data

February 25, 2020

Over the past decade, a new trend began to emerge, changing the way that clinical trials are conducted. Whereas placebo-controlled randomized control

 trials remain the gold standard, in some situations, single arm trials have become an accepted way of assessing a new treatment intervention. Single arm trials establish clinical benefit by demonstrating the positive effects of a new therapy or treatment, without the need to use placebo or standard of care as a control. Instead, alternative approaches of establishing the comparison 
are used; these have become known as external controls or synthetic control arms (SCA henceforth) and include approaches leveraging real world data from various sources or evaluations of historical clinical trial data.

Biotechs and Medtechs, don’t forget your market access strategy (part 4 of 4): How to optimize your market access planning approach

December 5, 2019

Author: Michael S. Paas, Market Access & Commercialization Expert, Executive at AbbVie and Guest Author at Cytel

In crafting your market access strategy, it can be valuable to follow these five best practices:

  1. Start planning as early as possible in the drug or device development process, to give yourself enough time to make informed, optimal decisions, and adjust your strategy when needed;
  2. Plan for global markets and seek early advice from payers and HTA agencies, where possible. There are many different agencies and payers to think about when you launch globally, so it’s vital to ensure you are sufficiently addressing the requirements of the priority markets. Even if you do not plan to commercialize by yourself in countries outside the US, careful, early market access planning with key global markets in mind can maximize the attractiveness of your asset to potential licensors or partners;

Biotechs and Medtechs, don’t forget your market access strategy (part 3 of 4): Harnessing the value of market access planning

December 2, 2019

Author: Michael S. Paas, Market Access & Commercialization Expert, Executive at AbbVie and Guest Author at Cytel

Addressing the myriad of considerations required for market access planning can be complex and time-consuming, so it is vital to give yourself enough time to make informed decisions. As such, starting to plan your market access strategy at least by early phase II or the proof-of-concept phase of device development can help you inform the design of the clinical program in such a way to ideally generate evidence credible and compelling to payer and HTA stakeholders, as well as regulators, in order to maximize the commercial success of your drug or device.

Planning early also gives you the opportunity to make adjustments along the trajectory of development as you gain new information and insights about the asset itself, as well as about the payer and competitive environment.

Biotechs and Medtechs, don’t forget your market access strategy (part 2 of 4): The critical role of market access planning in clinical development

November 21, 2019

Author: Michael S. Paas, Market Access & Commercialization Expert, Executive at AbbVie and Guest Author at Cytel

In my previous post, I established the importance of market access strategy in the clinical development process and why emerging biotechs cannot afford to overlook it.

Click on the button if you missed Part 1 or want to revisit it.

Read Part 1

It is imperative to start developing your strategy with market access due diligence and value story creation early in the product development (at least by phase II of drug development or the proof-of-concept phase of a device development). Impactful market access planning involves designing your clinical programs so they sufficiently address the evidence needs of market access stakeholders, patients, and regulators. This means demonstrating the value of your therapy to payers and HTA agencies by generating compelling and robust clinical trial data against appropriate comparators, augmented where possible and helpful with real-world evidence, health economic arguments, economic models and/or relevant patient-reported outcomes.

Biotechs and Medtechs, don’t forget your market access strategy (part 1of 4): Why is market access strategy crucial to succeed?

November 14, 2019

Market access strategy is an integral part of the clinical development process to ensure success in global healthcare markets and vital access to patients

Author: Michael S. Paas, Market Access & Commercialization Expert, Executive at AbbVie and Guest Author at Cytel 

In clinical development, it’s easy to underestimate the critical role that market access plays in the commercial success of a product. Understandably, organizations instead focus on the regulators, and the steps needed to secure eventual approval. However, ensuring the development plan is aligned with a well-planned market access strategy is essential to help the therapy actually reach the intended patients and realize its true commercial potential following regulatory approval. This is particularly crucial considering that payers and other key stakeholders demand compelling information on a drug’s/device’s value as well as justification of its pricing.

In this four-part blog series, I will address what can be done to optimize your market access planning, and why all that effort is really worth it.

The Good Data Submission Doctor - New ADaM Implementation Guidance

October 23, 2019

 

 
October 3, 2019 was an important day for the ADaM team as it marked the release of the ADaM Implementation Guidance (Ig) 1.2. Download the new guidance from the CDISC website here.


In 2018, several previews of the new Ig were made at CDISC Interchanges all around the world and at PhUSE conferences, it was only a few weeks ago that the final version was released. At first glance, the new Ig does not seem to contain a lot of new concepts and ideas. However, a critical and in-depth review clearly shows the efforts of the entire team to release this new Ig. Creating a new standard or releasing a new version of an existing standard is not an easy job. You need to ensure that you do not introduce anything that contradicts any of the existing CDISC standards. This includes, not only new variables but also any changes in existing sentences or adding entirely new sections that may cause misinterpretations or discrepancies. Moreover, every standard team member comes with their own background, company needs, and specific indication needs. It is not always easy to propose a solution that can satisfy everyone on the team.

The Challenges of Rare Diseases in Clinical Trials Symposium and Hands-on East Training

October 10, 2019

A disease is generally considered to be rare if it affects one patient per 200,000 people (1) and most rare diseases affect far fewer than this. However, collectively rare diseases are relatively common, affecting 350 million patients worldwide (2). The path to diagnosis for these patients is often a long, difficult battle and even once the diagnosis is made, it is likely there will be no suitable treatment available.  For 90% of rare diseases, there is no approved therapy (2). There is, therefore, a pressing need to develop new, effective therapies that can bring hope to rare disease patients. However, the clinical development environment for life-threatening, rare diseases is fraught with challenges. By their very nature, rare indications have few patients and limited sample size. This scarcity of patients also results in a lack of available information and knowledge about the disease from the best endpoints, to the treatment effect size or the variability of response between subgroups.

Digital transformation in healthcare and drug development

September 12, 2019

"If you went to bed last night as an industrial company, you're going to wake up today as a software and analytics company," CEO of GE, Jeff Immelt

We are living in a new digital world which is evolving every day. Both personally and professionally, we rely on technology for many of our routine activities, and examples of digitization are prevalent across industries. Retail is a big example of how several chains have moved from physical stores to creating an online presence. In some years from now, people perhaps won’t have to learn driving as more self-driven cars will hit the road. Healthcare does not fall far behind in this race towards digitization.

In this blog, we will examine some of the different ways that digitization is set to shift the drug development paradigm.

Advancing Medicines Development with External Controls

August 23, 2019

 

In place of collecting data from patients recruited for a trial who have been assigned to the control or standard-of-care arm, an external control creates a comparator arm using either real-world data-sets such as electronic health records or previous clinical trials.  The external control offers a practical, effective way to leverage real-world evidence and has been applied in regulatory approvals. In this blog, we share an illustrative example of how we can help customers in this emerging area of interest.

Predictive Biomarker Signature Characterization

August 1, 2019

 

 


The term biomarker signature describes the behavior of a set of biomarkers that define a signature to maximize the prediction performance. We examine the behavior of specific biomarkers as a set that consistently fluctuate together to maximize the accuracy on predicting the disease-related outcome.
How we apply a biomarker signature depends on the prediction problem. A prognostic biomarker signature is used to predict the disease progression, a risk biomarker signature is used to identify sets of subjects that are likely to develop a disease, and a predictive biomarker signature is used to determine the patients that are likely to respond to a particular treatment. Predictive biomarker signatures are used often in oncology to stratify patients with a specific cancer into sub-populations and develop targeted therapies for the diseased population subtypes defined by the biomarker signature.

In this blog, we share an example project that our data science team has worked on supporting this work.  The case study forms part of a new ebook 'Innovative Data Science and Real-World Analytics Approaches in Practice' and we are also delighted to provide the link for download as part of the article.

Adaptive Design and Health Economic Analysis: Interview with Laura Flight

July 22, 2019

 

 



Health economics and adaptive design methods share common ground in that they both aim to support more efficient and accurate decision making that can enable faster patient access to new health technologies. However, to date, there has been a limited understanding of how, if at all, the two approaches are being used together.

A paper, “A Review of Clinical Trials With an Adaptive Design and Health Economic Analysis,” exploring this important topic was published in the April 2019 issue of Value in Health (1) . In this blog, we catch up with Laura Flight, National Institute for Health Research (NIHR) Doctoral Fellow and the primary author of the paper for a deep dive into the objectives of the publication, key findings and the next steps for promoting better understanding in this area.

Flipping the paradigm-how should biotechs harness adaptive trials?

June 14, 2019

 

 

This article was originally published as part of a series by pharmaphorum in association with Cytel and is reproduced with their permission. Scott Harris, a four-time biotech Chief Medical Officer, and principal at Middleburg Consultants, a pharmaceutical consulting organization, told pharmaphorum’s Richard Staines that using novel adaptive or seamless clinical trial models can help to cut development costs. In doing so they can reduce the risks of trial failure that can spell the end for those biotech companies without the deep pockets of big pharma behind them. 

 

In case you haven’t noticed, the traditional three-phase clinical development process is changing. While big late-stage trials are still pretty common, it’s also no longer a surprise to see sponsors refer to phase 1/2 trials, or phase 2/3, indicating that a smaller trial can be progressed to the next phase if an interim data readout supports further evaluation.

This is known as a “seamless” trial as the boundaries between each development stage have become less defined, and there are other options too.

Middleburg Consultants’ Scott Harris is a proponent of this new way of working and has personal experience of the approach after using it to steer a gastroenterology drug through the approval process.
