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.

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.

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.

Operation Rescue: Addressing Lagging Trials

March 20, 2019

 


No one plans to have a trial whose data collection needs rescuing. However, lagging enrollment rates, operational struggles, and diminished budgets can leave some trials in need of intervention. A great deal has been written about how to prevent the need for rescues (e.g., more investment in study planning and improved communication between stakeholders). Far less has been said about how to assemble a rescue team – the roles that need to be filled and the process of analysis that ensures the completion of a failing trial.

Trends in Data Science: Podcast with Ursula Garczarek on The Effective Statistician

February 21, 2019

In 2018, Cytel ran a qualitative survey among biostatisticians and programmers on trends in data science and perceptions about the goals, barriers and future of the field in the biopharma and life science industry.  Our analysis and report revealed a range of insights from the respondents including :

Lack of shared understanding of what data science represents with less than 1 in 7 of all respondents suggesting a definition of data science.
Clear trend of investment in data science across organizational types with three-quarters of all respondents saying their organizations had a dedicated data science department.

An opportunity for improved clinical trial design by using data science techniques was recognized by the majority of respondents. In addition, respondents across all functions perceive the key opportunity for data science to be in maximizing the value of real-world data. 


In a recently published discussion on The Effective Statistician podcast ( a weekly podcast produced in association with PSI)  Ursula Garczarek, Associate Director Strategic Consulting at Cytel sat down with hosts Alexander Schacht and Benjamin Piske to discuss where the biopharma and life science industries are headed with the application of data science.

Publication Reveals New Promise for Promising Zone Designs

February 8, 2019

 

A 2018 publication in the  Biometrical Journal by Cytel’s Cyrus Mehta, Lingyun Liu and Sam Hsiao, ‘Optimal Promising Zone Designs’ (1) marks a new milestone for adaptive sample size re-estimation. Inspired by insights from the team's work with a number of Cytel's strategic consulting clients, it presents an easy to implement and new iteration of the popular promising zone design. The basic principle? That any investment of sample size at an interim analysis should be contingent on a minimal acceptable return on the investment. This return is expressed in terms of guaranteed conditional power, By identifying a minimum rate of return upfront, the new design offers greater efficiency to clinical trial planners. Importantly, the design concept is both easy to communicate, and easily understood among statistical and clinical stakeholders alike.
In this blog, Cytel Co-Founder and Fellow of the American Statistical Association, Cyrus Mehta shares his insights with us on the goals and key takeaways of the publication, and how it adds to the growing toolkit of intuitive adaptive designs available to drug developers today. We also share full access to the publication itself.

New publication addresses critical issues in ultra-orphan indications

November 5, 2018


Cytel biostatisticians Cyrus Mehta and Lingyun Liu, together with Charles Theuer, CEO of TRACON Pharmaceuticals have recently co-authored a publication in the journal Annals of Oncology: “ An Adaptive Population Enrichment Phase 3 Trial of TRC105 and Pazopanib Versus Pazopanib Alone in Patients with Advanced Angiosarcoma (TAPPAS Trial)”. The paper explores the features of this innovative population enrichment, adaptive sample size re-estimation trial and how it overcomes some fundamental challenges of clinical development in ultra-orphan oncology indications. The publication is timely, in the context of the August 2018 news that the FDA has launched a complex and innovative designs pilot program to facilitate and advance the use of complex adaptive, Bayesian, and other novel clinical trial designs in late-stage drug development. The initiative seeks to further innovation by allowing the FDA to publicly discuss those trial designs that are being considered through the pilot program. Indeed, the TAPPAS trial incorporated regulatory input from both the FDA and EMA and received a Special Protocol Assessment from the FDA. As of the date of publication, the authors were not aware of any other pivotal population enrichment trial that has been implemented in oncology, and therefore the paper’s deconstruction of the design’s key elements will be invaluable to researchers considering similar innovative approaches.

The "Master Recipe": Quality and Attention to Details Matter When Submitting CDISC Packages to Authorities

October 1, 2018

One of my wife’s favorite TV shows is ‘Quattro Ristoranti’ (Four Restaurants). In each episode of the show, 4 restaurants of the same style are assessed and the one getting the best evaluation wins the prize. One of the first things the TV presenter Alessandro Borghese, a famous Italian chef, does while visiting the restaurant is to assess (of course!) the kitchen and how much the kitchen and its tools are cleaned. This assessment could have a big impact on the final outcome regardless of the quality of the food served in the restaurant .... the state of the kitchen and its cleanliness influences Borghese’s faith in the chef’s work.

This is exactly what could happen in a data submission to health authorities such as the FDA: the efficacy and safety of your drug are of course what matter, but lack of traceability, or poor or insufficient documentation might trigger questions and concerns from the reviewer. While this might not impact the overall final outcome of your submission, approval could be delayed if the reviewer starts questioning what you have done by requesting changes, or new deliverables to clarify the aspects that were not sufficiently clear in your original submission.

Novel immunotherapies lean on old methods (or how to teach your dragon old tricks)

September 17, 2018

 

Immunotherapy has brought us many promises, most notably, of a future where humans are able to harness their body’s own ability to protect them from illness. Immuno-oncology (IO) may be the ultimate frontier of that future reality, with a promise of being able to help our bodies deflect or cure us of any malignancies. Today, these therapies include cell therapies, cancer vaccine, and T-cell–stimulating antibodies, with the field continuously expanding.

While medical science behind immune-oncology (IO) treatments is fascinating and expanding at a rapid pace, so too are the statistical challenges posed by the development of these agents.

September 10, 2018

 

The biopharmaceutical and healthcare industries now collect more data than ever before due to advances in the variety of information sources combined with the ability to store vast quantities of diverse data. Sophisticated machine learning (ML) and artificial intelligence (AI) techniques allow us to access
and analyze any combination of a multitude of data sources. The way that traditional controlled sources are viewed is being adapted in light of new evidence that emerges from real-world data. A recent Deloitte survey (1) found that 90 percent of biopharma companies are making significant investments in
real-world evidence capabilities to drive drug development and meet regulatory requirements.

Real-world evidence (RWE) has historically been used for post-marketing endorsement and in pricing and reimbursement negotiations. But could data science offer an opportunity to fundamentally shift this
paradigm, leading to better and more affordable medications being approved on the basis of RWE?

In June 2018, Cytel created and ran a survey asking respondents from our audience about the potential of data science approaches in the sector.  We are now excited to share the insights from the survey* ( designed as a qualitative pulse check) which reveal a powerful potential shift in the current drug development and approval paradigm.

Building interactive web applications using R Shiny

August 1, 2018

By Gordhan Bagri and Munshi Imran Hossain with  H A S Shri Kishore

Shiny (from RStudio) is one of the most popular R packages. The package allows programmers to create applications with interactive user interfaces. These applications can then be deployed for non-programmers to perform analysis. Non-programmers can, therefore, make use of the statistical capabilities of R by means of point and click. This is one of the reasons why its use has been on the rise in the last few years.

Unveiling New East 6.5 Modules: Join Our Webinar

July 3, 2018

 

 It’s shaping up to be a busy year for Cytel’s software development team with a number of upgrades and planned launches across our range of tools. (Watch this space for announcements soon on new quantitative decision-making software OK GO and an upgrade to EnForeSys). East, our industry leading platform for clinical trial design, simulation, and monitoring will be unveiling version 6.5 in the Fall, and delegates at the PSI conference in early June had the chance to grab a sneak peek of the new functionality in one to one demos.

We’ll also be opening the hood on the new design capabilities you can expect in East 6.5 at a complimentary webinar on Wednesday July 18, 11:00AM - 12:00 US EDT (16:00 UK, 17:00 EU).

Our presenters Pantelis Vlachos and Charles Liu, will introduce the 3 new available modules and share their insights on the supporting methodologies and their practical applications. New developments in the East software are typically derived from two sources: our team’s interaction with our customers, particularly during East training; and from our consulting practice when we help clients design their trials.

The new modules in East 6.5 include:
MCPMod (design with Multiple Comparisons Procedures)

MCPMod allows you to measure the likelihood that particular dose-response curves are the right mathematical model for a given set of data. East MCPMod will allow designing a trial using optimal allocation and then analyze the trial data using various dose/model selection criteria resulting
into a solid base (target dose) for the next phase confirmatory trial.

Population Enrichment (Adaptive designs)

An adaptive enrichment design allows the full population is segmented during interim analyses. Recently, we worked with TRACON Pharmaceuticals to design their TAPPAS trial that incorporated a population enrichment component to help overcome the potential heterogeneity of treatment effect between subpopulations for an angiosarcoma design.

Program-Level Design
It is important to take a strategic approach to clinical development to minimize the potential for Phase 3 attrition. This new module will help users apply simulations to optimize their clinical trial programs.

Measuring lots of little details: Non-Compartmental Analysis and the Early Phase Regulatory Environment.

June 28, 2018

 

By Esha Senchaudhuri

With thanks also to Jitendarreddy Seelam and Ramanatha Saralaya for their input.

The fact of the matter is that I now want to recall everything, every trifle, every little detail. I still want to collect my thoughts and - I can't, and now there are these little details, these little details...”
― Fyodor Dostoyevsky, The Meek One

Old Fyodor was hardly talking about clinical trials, but early phase trial sponsors can probably relate to a regulatory environment which requires systematic attention to details, the little details and all these little details. When conducting early phase studies, global regulators require submission of Non -Compartmental Analyses (NCAs) that measure factors such as extent and rate of exposure to a drug, without the complexity of strenuous assumptions or complex models. Through the use of rudimentary methods such as linear trapezoidal rules, NCAs make it relatively easy to measure the concentration of a drug in a body over time. They can capture length of exposure, and time of peak exposure, without the challenges of models that require independent validation [1]. While those other models are also becoming more common in quantitative pharmacometrics, ideally NCAs can complement these other methods.


It may be tempting to assume that due to the ease of measurement, it is unnecessary to invest in statistical expertise and reliable software for NCAs. While the calculations may not be as complex as other forms of pharmacometric modeling, taking shortcuts at this stage can prove problematic later on. 
Widely recognized for being ‘assumption-free’ [1] NCAs are a common subject of regulatory inquiries. Exposure and absorption data is obviously important for early phase trials, so NCAs are required for submission throughout the process. A strong data management system with reliable software can ensure that findings collected at this stage are streamlined across several early phase trials, making such information easy to access and ensuring a rapid response for regulators. Further, NCAs are often required to be submitted with early protocols making it useful to have statistical designers familiar with the NCA findings. As NCAs are an integral part of establishing an early phase audit trail, it is important to use NCA software that streamlines a detailed and complex workflow such as Phoenix WinNonlin. 


Accurate NCAs can combine with other forms of quantitative pharmacometric models like PK/PD analysis to build strong dose-response models for Phase 2. It is common knowledge that unreliable dose-response models in Phase 2 can create headaches for Phase 3 tests. Only 13.2% of Phase 3 trials that are accepted after initial rejection, are rejected on grounds of efficacy. More common reasons are dose selection, choice of endpoints, and other challenges that better Phase 2 modeling can prevent [2]. Working with statistical experts as early as Phase 1 can ensure that knowledge gleaned from NCAs can be employed to build stronger Phase 2 models, thus avoiding Phase 3 pitfalls.

By Ivan Navarro, Data Scientist at Cytel

R is an open-source implementation of ‘S’, the statistical programming language. With its open character and ability to extend its functionality using external packages, R allows users to create their own packages that are easily loadable into the core instance.
In essence, R-packages are extensions that contain source-code, documentation, data and examples of personal contributions and can be extremely useful for data scientists, statisticians and programmers alike who need to create custom analysis and visualizations. However, creating your first R-package can be a complex task for non-experienced users.
In this blog, I explain how to create a basic R-package which can be used as template for anyone interested in making a contribution. A previous knowledge on R programming is required, but you will not need to deal with technical aspects of the creation process because the R-Package structure is shared at the end.

Addressing the Problem of Feature Selection Using Genetic Algorithms

January 15, 2018

The problem of feature selection

The explosion in the availability of big data has made complex prediction models a conspicuous reality of our times. Whether in banking, financial services and insurance, telecoms, manufacturing or healthcare, predictive models are increasingly used to derive inference from data.

Most of these models use a set of input variables, called features, to predict the output on a variable of interest. For example, the concentration of characteristic biomarkers in the blood can be used to predict the presence, absence or progress of certain diseases.

The available data can provide a large number of features, but generally, it’s preferable to use a small number of really relevant features in a model. This is because a model with more features has a greater complexity which leads to greater demand on computational resources and time to train the model. Therefore it is desirable to restrict the number of features in a predictive model. Choosing the subset of features that will result in a model with optimum performance is the problem of feature selection. This is essentially a problem of plenty.

How Can We Tackle Heterogeneity in Meta-Analysis?

January 3, 2018

Health professionals and policy makers want to make healthcare decisions based on the relevant research evidence. The questions in clinical research are typically studied more than once independently by different researchers. Literature review is used for summarizing the results of these studies and strengthening the evidence. Systematic review is a type of literature review that collects and critically analyzes multiple research studies or papers that answer the same question. If the results of these multiple studies are diverse and conflicting then the clinical decision-making becomes difficult. To overcome this problem meta-analysis is used. Meta-analysis is a statistical procedure for combining the results of studies that are included in systematic review. While meta-analysis is a powerful technique, it may give misleading results due to issues like improper selection of studies, publication bias, and heterogeneity among studies. In this blog, we will focus on the problem of heterogeneity.

Signal Management Using R

December 12, 2017


Signal management is one of the most audited pharmacovigilance processes. It also generates one of the highest findings from audits. The ability of Marketing Authorisation Holders (MAHs) to make a robust signal management system that is fully audit/inspection ready sometimes falls short of expectations.
