Maximizing Real-World Data: Impact of Cardiovascular Disease on Clinical Outcomes in Rheumatoid Arthritis

Current guidance on rheumatoid arthritis (RA) stresses the importance of considering Clinical Outcomes in RAcomorbidity when assessing disease activity and making clinical decisions.1 Comorbidities commonly associated with RA include cardiovascular disease (CVD), lung disease and malignancy.2

The complex relationship between RA and CVD comorbidities

The presence of CVD itself has been shown to increase the risk of death in RA patients by approximately 50%,3 and there is an emerging relationship between RA, CVD and the therapies used to treat them. Continue reading

Assessing Pharmacokinetics in Diabetic Patients with Impaired Renal Function

Pharmacokinetic (PK) data guide the safe and effective management of a drug Pharmacokinetics in Diabetic Patients with Impaired Renal Functiontreatment; however, with diabetic patients, PK studies can be especially challenging. Varying degrees of kidney disease in patients can affect the PK characteristics of the drug and the reliability of the study results.

From screening patients to determining doses, testing a drug for diabetic patients involves several important considerations.

The importance of early work

Even before a drug reaches the clinical stages, early work can help set the stage. Preclinical research is very important in identifying agents with activity in the diabetic spectrum, while studies in early toxicology provide valuable direction as to whether the risks are acceptable in the diabetic population.

Given that most diabetic drugs affect the kidneys, performing an early renal study on a model can determine if the drug has a future in the diabetic space and may help guide earlier go/no-go decisions ‒ before allocating additional resources to the efforts. Continue reading

Pop Quiz: What’s Your Patient Centricity IQ?

What issues do patients cite as barriers to clinical study participation? How far are they willing to travel to participate in a study and how much more willing are they to participate knowing that their physician is aware of the study?Patient Centricity Quiz

We asked these questions – and more – to group of 135,000 people who opted in to the LabCorp database to receive more information about Covance clinical studies. More than 2,500 responded to our survey, providing our team with unique insights to better understand the patient mindset and design more effective recruitment strategies.

Next, to see if our colleagues in the drug development industry could surmise our participants’ aggregate answers from this survey, we delivered a short pop quiz. Any attendees who stopped by our booth at the 2017 Drug Information Association annual meeting (DIA), had a chance to take the quiz and see how they fared. Continue reading

A Practical Business Approach to Data Management for Clinical Trial Efficiency

Today’s clinical trials have become more complex and expensive, pressuring pharmaceutical companies to further improve their clinical trial operations. Clinical trial data management is one area where both sponsors and contract research organizations (CROs) can uncover new efficiencies, increase cost-saving measures and better meet diverse operational reporting needs across the clinical development cycle.

In this blog we begin to examine the current issues with traditional electronic data capture systems and other current “big data” approaches that attempt to address complex operational reporting needs in this historically stagnant and underserved area. We also discuss the use of two distinct data repositories – an operational data warehouse and a clinical data warehouse – the Xcellerate® Clinical Data Hub as part of a new data model through the Xcellerate Informatics Suite to provide a significant technological advance in clinical trial operations.

Understanding the Power of Natural Killer Cells and New Nonradioactive Assay Approaches

Natural killer (NK) cells first earned their title as “killers” nearly 40 years ago when researchers observed the rapid immune response of these lymphocytes as they destroyed host cells infected with a virus or tumor cells. It seemed that NK cells could attach spontaneously without prior activation. Over time, researchers have learned more about the molecular mechanisms that regulate their activation and function.

Today, the NK cell assay is used to support specialty immunotoxicology studies for safety assessment. At Covance, we work with clients that often ask us about performing a NK cell functional analysis and the role of standard immunophenotyping to enumerate cells. This article addresses these questions by providing a brief background on the innate immunity of NK cell biology and comparing assay methods. Continue reading

Investing in the Future of Precision Medicine

In previous posts on this blog, our scientists have described the current state of precision medicine, particularly how it relates to companion diagnostics (CDx) and immuno-oncology. As an enterprise, we have been focused on this area of medicine essentially from the beginning, more than 20 years ago. LabCorp Diagnostics developed the clinical trials assay and served as the central lab for the testing of HER2-positive breast cancer during the development of trastuzumab. The company provided analytical testing data for the associated immunohistochemistry laboratory test resulting in the first companion diagnostic approved by the FDA. More recently, Covance was instrumental in supporting the drug development efforts for pembrolizumab, the therapy used successfully to treat former President Jimmy Carter’s melanoma, and its associated companion diagnostic.

An Analytical Approach to Enhance Recruitment of Rheumatoid Arthritis Patients

No single blood test or physical finding alone can confirm the diagnosis of rheumatoid arthritis (RA). However, two tests that detect markers of inflammation are often ordered when RA is suspected: erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Other common tests include rheumatoid factor and anti-CCP antibodies.

RA patients in the United States

While the test results are clearly valuable to the requesting physician to inform diagnostic decisions, sponsors can also leverage this information to support patient recruitment in an increasingly competitive space. We recently evaluated how de-identified patient data from these common tests run by LabCorp can support sponsors’ clinical trials in rheumatoid arthritis. Continue reading
