Open repositories VS the Publisher

On March 18th the MIT introduced a policy requiring all scholarly articles written by its faculty members to be made freely available in an open access repository. While researchers understandably applaud the free and open dissemination of data, there are questions that should be considered with regards to the impact of a growing number of open repositories on the value added by Publishers, and how this value would be retained if in the long term the open access journal turns out to be unsustainable.

How important is the value added by the Publisher (and this is not an open access versus non-open access journal debate)? While the peer review process is certainly not without its failings, to any Publisher or Editor worth their salt, the integrity of the peer review process is paramount. To quote a previous blog post on this site, an author of a CMRO article on receiving his peer review comments said "I have never received 58 referee comments on a manuscript less than 3000 words long, but the referees' comments and the revision definitely improved the paper." An author of a recent paper submitted to Expert Opinion on Medical Diagnostics fed back "a comment about the reviewers: it was clear that they read the manuscript carefully. Regardless of whether they agreed with some of our arguments, their comments reflected readers that thought about what they read. This is how peer review is supposed to work. Excellent reviewer selection on your part, and a thorough job on theirs." Aside from assisting the author in critically reviewing their work and ultimately leading to a better paper, without the peer review process how do we ensure no dangerously inaccurate information is published that is indistinguishable from high calibre scientific research?

And it’s not just in the peer review that value is added by the Publisher. Who checks references are cited correctly and terms are not misspelled - will the institutions running their own open access repositories employ copyeditors? Who will ensure the figures are legible and of good quality – will the institutions employ production editors who lay the work out in such a way that it is easy on the eye and doesn’t give readers a headache? Will there be any independent quality check before the research is published? With a limitless amount of potentially unqualified freely available literature, how will the busy physician who only has 5 minutes in his/her day to digest the most important findings even know where to start? These are just a few of the questions that would need to be answered.

Ok, I’m playing devil’s advocate a little here. I do not envisage a world where the peer-reviewed journal ceases to exist, but the open access model of publishing is widely debated, both in terms of quality and sustainability. So what is the future of publishing? Even if the open access, pay to publish model is viable in the long term, does the scientific community agree to paying to publish all of their work in the future, rather than pay to read the work of others? The fact is, publishing a journal is a costly business and the money has to come from somewhere. Publishers are accused of placing scientific research behind ‘commercial barriers’, but surely the same argument could be applied to the pay to publish model. Is it fair that only authors with funding can afford to have it published? Will this lead to a bias in the literature towards sponsored research, not even so much through the choices of the Editor, but through the fact that only authors who can pay can publish? Or is there an alternative, free to publish, free to read, sustainable model for open access publishing that still maintains high standards of peer review and editorial quality?

While Publishers undoubtedly need to take steps to ensure the advancement of science through the widest possible dissemination of research, with respect to the whole principal of open access, how do we do this for free? Surely someone, somewhere has to pay something?

In summary:

• How important is value added by the Publisher?
• How will high calibre research be distinguished?
• How will the reader filter the wealth of freely available literature?
• Does the scientific community want to pay to publish all of their work in the future?
• Could this lead to bias in the literature?
• What if the pay to publish model doesn't work?
• Is there an alternative, free to publish, free to read, sustainable model for open access publishing that still maintains high standards of peer review and editorial quality?

Expert Opinion on Therapeutic Patents and Journal of Medical Economics selected for indexing in MEDLINE

Informa Pharmaceutical Science is delighted to announce that Expert Opinion on Therapeutic Patents (EOTP) and the Journal of Medical Economics (JME), have been selected for indexing in MEDLINE.

A widely used bibliographic database compiled and maintained by the US National Library of Medicine, MEDLINE is freely accessible via the PubMed search engine. It is worth noting that the decision by MEDLINE to index or not a journal is based on a review by the Literature Selection Technical Review Committee upon application. The main criteria for selection, which go beyond sound science and thorough peer review, are listed here.

We are very pleased by this decision which will deservedly increase the visibility of JME and EOTP articles.

Reuben’s Research: A Pain In The Analgesia

Research on multimodal analgesia took a hit when one of its leading proponents, Scott S. Reuben, MD – aka the Medical Madoff - was caught fudging his data. Baystate Medical Center’s internal review board launched a full-fledged investigation into Reuben’s work last May when he appeared to be conducting studies on humans without approval. The investigation, completed in January, uncovered some 21 published articles—dating as far back as 1996—in which Reuben made up some or all of the data. Baystate's chief academic officer is quoted as saying that in many cases, "there was no clinical trial because there were no patients." Whew!

At least it looks like nobody got hurt. But the incident raises questions in our industry that beg for answers:

Where Were The Peer Reviewers? In my opinion, that’s an unfair question some people are asking. Peer reviewers, and editors for that matter, can only work with the data they’re given. We can’t be expected to show up on every study site to make sure a prospective author’s data is pure before we decide to accept it for publication.

Why did it take 13 years to catch him? We can only speculate on why it took so long to uncover Reuben’s fraud, but it may have been because, like the Piltdown Man, nobody was taking his research all that seriously—nobody else could replicate his findings. Replication, albeit slow, is the surest way to keep fraud in check.

What was Industry’s role? Outside of partially funding some of Reuben’s research—and there’s nothing inherently wrong with that--Pfizer is not suspected of any wrongdoing. However, Reuben’s relationship with Pfizer, at least in the papers I was able to fully access, was not properly disclosed in most cases.

Would full disclosure have mattered? I think so. Knowing the financial ties an author has to a study’s sponsor alerts readers to the potential for biased results.

What Can Be Done About It? Reuben’s case is every Editor’s worst nightmare. Patient care is ultimately affected by erroneous data. While CMRO has never published a Reuben paper, something like this could happen to us. But rest assured that we are doing everything within our power to prevent such a thing from happening.

All CMRO articles undergo such a stringent peer review process that caused one author recently to say, “I have never received 58 referee comments on a manuscript <3000 words long, but the referees' comments and the revision definitely improved the paper.” We will also be introducing new measures soon to stay at the forefront of ethical publishing - keep your eyes open for more news soon.

Phospholipases may not be targets of choice for medicinal chemistry, but two inhibitors are now in clinical development for atherosclerosis

By Editorial Board member Dr Keith Suckling

Phospholipases do not appear high on the list of major druggable target types. There are significant challenges in medicinal chemistry to provide specificity and in enzymology to generate data that can support chemistry for reactions that take place at a lipid-water interface at which active concentrations of compounds are difficult to define. So it is perhaps surprising that there are now two phospholipase inhibitors in clinical development for the treatment of atherosclerosis - surprising because of the chemical challenges but also because the final proof of efficacy in patients requires extended outcome studies in around 16,000 subjects.

The first of these compounds is darapladib (GSK) for which Phase 2 results were presented last year [1]. Darapladib inhibits the enzyme known as lipoprotein-associated phospholipase A2. As the name suggests, this phospholipase is found in the circulation associated with LDL and is thought to catalyse the hydrolysis of oxidised phospholipids. The products of the hydrolysis promote the expression of adhesion molecules on the artery wall and chemokines in macrophages and so promote the development of the vulnerable plaque. Inhibition of this process would therefore be expected to be of benefit and recent studies in a pig model support this concept [2] and some of the Phase 2 data are consistent with it too. This mechanism would be expected to have a similar overall effect on the pathogenesis of atherosclerosis to a chemokine receptor antagonist, for example CCR2. Importantly this approach does not reduce plasma LDL, and is not expected to.

Other forms of phospholipase have been implicated in atherogenesis in recent years and in particular those known as secretory phospholipases [3], of which the Group V enzymes have been of particular interest. Animal data also supports a role for these enzymes in atherogenesis [4], but the mechanism is different. In this case the phospholipase modifies HDL and LDL particles making the former less able to support reverse cholesterol transport and the latter more susceptible to oxidation. Very recently Phase 2 data have been reported of the effects of an sPLA2 inhibitor, varespladib (A-002, Anthera Pharmaceuticals) [5]. This compound inhibits a range of sPLA2 s (sPLA2-IIa>sPLA2-X>sPLA2-V) and, in contrast to darapladib, does have an effect on plasma LDL concentration and also on hsCRP. Recent animal data are consistent with an effect of varespladib on atherogenesis in the mouse [6]

It is important to recognize that the effects of these two phospholipase inhibitors on the process of atherogenesis are quite different and as a result, at least in Phase 2, they require different end points to be studied. If this is not borne clearly in mind there is a danger of serious confusion amongst non-experts. In this respect we should no more talk about phospholipase inhibitors as a class than we might about PPAR agonists: there are so many differences. Nevertheless, for both mechanisms, it is necessary to show that they improve outcomes in patients, and at this point the differences are not important. A large outcome study is beginning for darapladib (STABILITY) with around 15,000 patients [7].

Drug-drug interactions in oncology: from mechanisms to patient perception

Drug-drug interactions in oncology represent a highly problematic issue to resolve. The events that give rise to clinically significant drug-drug interactions are inherently driven by cancer patients that are often being medicated by more than one drug. Polypharmacy in oncology can result in alterations of chemotherapeutic pharmacokinetic profiles via multiple mechanisms affecting the pharmacodynamics of drugs that are closely related to their pharmacokinetic profiles. In their review article,Mani and colleagues critically analyze the mechanisms by which drug-drug interactions in oncology alter pharmacokinetics and also explore the emerging field of transcriptional control of enzyme/transporter action and its impact on altered drug clearance. Adding another layer of complexity to drug-drug interactions in oncology is the patient’s perception of the definition of a “drug”. Cancer patients undergoing treatment with chemotherapeutics who also consume over-the-counter medications, herbal remedies or supplements without informing their physician run the risk of unknowingly exposing themselves to potentially dangerous drug-drug interactions. In her Editorial article, Professor Marie Hanigan highlights the dangers of patients taking treatment advice from unreliable sources or misinterpretation of the scientific literature and calls for a more in-depth inquiry by the physician into the consumption of non-prescription medicines and other supplements by cancer patients. Professor Hanigan describes the lack of knowledge and confusion among cancer patients regarding the dangers of drug-drug interactions and addresses the challenges facing this large and complex field.
