ue Medicamentos biosimilares: Lo que los pacientes deben saber By www.flickr.com Published On :: Mon, 12 Aug 2024 11:55:28 -0700 The U.S. Food and Drug Administration posted a video: ¿Qué son los biosimilares? Los biosimilares son un tipo de medicamento que se usa para tratar una variedad de afecciones, como enfermedades crónicas de la piel y los intestinos, artritis, diabetes, afecciones renales, degeneración macular y algunos tipos de cáncer. Un biosimilar es un tipo de medicamento biológico. La mayoría de los medicamentos biológicos se elaboran usando fuentes vivas, como células animales, bacterias o levaduras. Debido a que en su mayoría provienen de fuentes vivas, todos los tipos de productos biológicos tienen diferencias menores que ocurren naturalmente entre los lotes de producción. Así como los medicamentos de marca tienen versiones genéricas, los biológicos originales pueden tener biosimilares. La cuidadosa revisión de datos, estudios y pruebas por parte de la FDA ayuda a garantizar que los productos biosimilares brinden los mismos beneficios de tratamiento que el producto biológico original aprobado por la FDA. Los biosimilares pueden brindarle más acceso a tratamientos importantes y también pueden ahorrarle dinero, dependiendo de su cobertura de seguro. Se han aprobado muchos biosimilares diferentes y se esperan aún más. Para obtener más información, visite www.fda.gov/biosimilars Full Article

ue Funding Cutbacks at FDA: A Sequester Primer By www.fdamatters.com Published On :: Thu, 07 Mar 2013 17:59:38 +0000 At a time when FDA’s responsibilities continue to grow rapidly, the agency has been caught in an across-the-board reduction (sequester) in federal discretionary spending, effective March 2, 2013. Although Congress may yet reverse course and restore money to affected federal agencies, this is not considered a high probability. Altogether, FDA will lose about $209 million between now and September 30, 2013. This will reduce inspections, slow drug and device approvals, and restrict implementation of the Food Safety Modernization Act and other recent legislation. Because of the many questions about the process and outcome, this is FDA Matters’ primer on the sequester of FDA funds. Full Article FDA and Congress FDA Appropriations Planning for FDA's Future

In fact, the report’s authors appear to know nothing about the federal budget and have used inherently unreliable data in calculating FY 13 and FY 14 spending levels.

ue Questionable Enrollment Math at the UK's NIHR By www.placebocontrol.com Published On :: Mon, 16 Sep 2013 18:04:00 +0000 There has been considerable noise coming out of the UK lately about successes in clinical trial enrollment. First, a couple months ago came the rather dramatic announcement that clinical trial participation in the UK had "tripled over the last 6 years". That announcement, by the chief executive of the Sweet creature of bombast: is Sir John writing press releases for the NIHR? National Institute of Health Research's Clinical Research Network, was quickly and uncritically picked up by the media. That immediately caught my attention. In large, global trials, most pharmaceutical companies I've worked with can do a reasonable job of predicting accrual levels in a given country. I like to think that if participation rates in any given country had jumped that heavily, I’d have heard something. (To give an example: looking at a quite-typical study I worked on a few years ago: UK sites were overall slightly below the global average. The highest-enrolling countries were about 2.5 times as fast. So, a 3-fold increase in accruals would have catapulted the UK from below average to the fastest-enrolling country in the world.) Further inquiry, however, failed to turn up any evidence that the reported tripling actually corresponded to more human beings enrolled in clinical trials. Instead, there is some reason to believe that all we witnessed was increased reporting of trial participation numbers. Now we have a new source of wonder, and a new giant multiplier coming out of the UK. As the Director of the NIHR's Mental Health Research Network, Til Wykes, put it in her blog coverage of her own paper: Our research on the largest database of UK mental health studies shows that involving just one or two patients in the study team means studies are 4 times more likely to recruit successfully. Again, amazing! And not just a tripling – a quadrupling! Understand: I spend a lot of my time trying to convince study teams to take a more patient-focused approach to clinical trial design and execution. I desperately want to believe this study, and I would love having hard evidence to bring to my clients. At first glance, the data set seems robust. From the King's College press release: Published in the British Journal of Psychiatry, the researchers analysed 374 studies registered with the Mental Health Research Network (MHRN). Studies which included collaboration with service users in designing or running the trial were 1.63 times more likely to recruit to target than studies which only consulted service users. Studies which involved more partnerships - a higher level of Patient and Public Involvement (PPI) - were 4.12 times more likely to recruit to target. But here the first crack appears. It's clear from the paper that the analysis of recruitment success was not based on 374 studies, but rather a much smaller subset of 124 studies. That's not mentioned in either of the above-linked articles. And at this point, we have to stop, set aside our enthusiasm, and read the full paper. And at this point, critical doubts begin to spring up, pretty much everywhere. First and foremost: I don’t know any nice way to say this, but the "4 times more likely" line is, quite clearly, a fiction. What is reported in the paper is a 4.12 odds ratio between "low involvement" studies and "high involvement" studies (more on those terms in just a bit). Odds ratios are often used in reporting differences between groups, but they are unequivocally not the same as "times more likely than". This is not a technical statistical quibble. The authors unfortunately don’t provide the actual success rates for different kinds of studies, but here is a quick example that, given other data they present, is probably reasonably close: A Studies: 16 successful out of 20 Probability of success: 80% Odds of success: 4 to 1 B Studies: 40 successful out of 80 Probability of success: 50% Odds of success: 1 to 1 From the above, it’s reasonable to conclude that A studies are 60% more likely to be successful than B studies (the A studies are 1.6 times as likely to succeed). However, the odds ratio is 4.0, similar to the difference in the paper. It makes no sense to say that A studies are 4 times more likely to succeed than B studies. This is elementary stuff. I’m confident that everyone involved in the conduct and analysis of the MHRN paper knows this already. So why would Dr Wykes write this? I don’t know; it's baffling. Maybe someone with more knowledge of the politics of British medicine can enlighten me. If a pharmaceutical company had promoted a drug with this math, the warning letters and fines would be flying in the door fast. And rightly so. But if a government leader says it, it just gets recycled verbatim. The other part of Dr Wykes's statement is almost equally confusing. She claims that the enrollment benefit occurs when "involving just one or two patients in the study team". However, involving one or two patients would seem to correspond to either the lowest ("patient consultation") or the middle level of reported patient involvement (“researcher initiated collaboration”). In fact, the "high involvement" categories that are supposed to be associated with enrollment success are studies that were either fully designed by patients, or were initiated by patients and researchers equally. So, if there is truly a causal relationship at work here, improving enrollment would not be merely a function of adding a patient or two to the conversation. There are a number of other frustrating aspects of this study as well. It doesn't actually measure patient involvement in any specific research program, but uses just 3 broad categories (that the researchers specified at the beginning of each study). It uses an arbitrary and undocumented 17-point scale to measure "study complexity", which collapses and quite likely underweights many critical factors into a single number. The enrollment analysis excluded 11 studies because they weren't adequate for a factor that was later deemed non-significant. And probably the most frustrating facet of the paper is that the authors share absolutely no descriptive data about the studies involved in the enrollment analysis. It would be completely impossible to attempt to replicate its methods or verify its analysis. Do the authors believe that "Public Involvement" is only good when it’s not focused on their own work? However, my feelings about the study and paper are an insignificant fraction of the frustration I feel about the public portrayal of the data by people who should clearly know better. After all, limited evidence is still evidence, and every study can add something to our knowledge. But the public misrepresentation of the evidence by leaders in the area can only do us harm: it has the potential to actively distort research priorities and funding. Why This Matters We all seem to agree that research is too slow. Low clinical trial enrollment wastes time, money, and the health of patients who need better treatment options. However, what's also clear is that we lack reliable evidence on what activities enable us to accelerate the pace of enrollment without sacrificing quality. If we are serious about improving clinical trial accrual, we owe it to our patients to demand robust evidence for what works and what doesn’t. Relying on weak evidence that we've already solved the problem ("we've tripled enrollment!") or have a method to magically solve it ("PPI quadrupled enrollment!") will cause us to divert significant time, energy, and human health into areas that are politically favored but less than certain to produce benefit. And the overhyping those results by research leadership compounds that problem substantially. NIHR leadership should reconsider its approach to public discussion of its research, and practice what it preaches: critical assessment of the data.

ue Questionable Enrollment Math(s) - the Authors Respond By www.placebocontrol.com Published On :: Fri, 20 Sep 2013 04:09:00 +0000 The authors of the study I blogged about on Monday were kind enough to post a lengthy comment, responding in part to some of the issues I raised. I thought their response was interesting, and so reprint it in its entirety below, interjecting my own reactions as well. There were a number of points you made in your blog and the title of questionable maths was what caught our eye and so we reply on facts and provide context. Firstly, this is a UK study where the vast majority of UK clinical trials take place in the NHS. It is about patient involvement in mental health studies - an area where recruitment is difficult because of stigma and discrimination. I agree, in hindsight, that I should have titled the piece “questionable maths” rather than my Americanized “questionable math”. Otherwise, I think this is fine, although I’m not sure that anything here differs from my post. 1. Tripling of studies - You dispute NIHR figures recorded on a national database and support your claim with a lone anecdote - hardly data that provides confidence. The reason we can improve recruitment is that NIHR has a Clinical Research Network which provides extra staff, within the NHS, to support high quality clinical studies and has improved recruitment success. To be clear, I did not “dispute” the figures so much as I expressed sincere doubt that those figures correspond with an actual increase in actual patients consenting to participate in actual UK studies. The anecdote explains why I am skeptical – it's a bit like I've been told there was a magnitude 8 earthquake in Chicago, but neither I nor any of my neighbors felt anything. There are many reasons why reported numbers can increase in the absence of an actual increase. It’s worth noting that my lack of confidence in the NIHR's claims appears to be shared by the 2 UK-based experts quoted by Applied Clinical Trials in the article I linked to. 2. Large database: We have the largest database of detailed study information and patient involvement data - I have trawled the world for a bigger one and NIMH say there certainly isn't one in the USA. This means few places where patient impact can actually be measured 3. Number of studies: The database has 374 studies which showed among other results that service user involvement increased over time probably following changes by funders e.g. NIHR requests information in the grant proposal on how service users have been and will be involved - one of the few national funders to take this issue seriously. As far as I can tell, neither of these points is in dispute. 4. Analysis of patient involvement involves the 124 studies that have completed. You cannot analyse recruitment success unless then. I agree you cannot analyze recruitment success in studies that have not yet completed. My objection is that in both the KCL press release and the NIHR-authored Guardian article, the only number mentioned in 374, and references to the recruitment success findings came immediately after references to that number. For example: Published in the British Journal of Psychiatry, the researchers analysed 374 studies registered with the Mental Health Research Network (MHRN). Studies which included collaboration with service users in designing or running the trial were 1.63 times more likely to recruit to target than studies which only consulted service users. Studies which involved more partnerships - a higher level of Patient and Public Involvement (PPI) - were 4.12 times more likely to recruit to target. The above quote clearly implies that the recruitment conclusions were based on an analysis of 374 studies – a sample 3 times larger than the sample actually used. I find this disheartening. The complexity measure was developed following a Delphi exercise with clinicians, clinical academics and study delivery staff to include variables likely to be barriers to recruitment. It predicts delivery difficulty (meeting recruitment & delivery staff time). But of course you know all that as it was in the paper. Yes, I did know this, and yes, I know it because it was in the paper. In fact, that’s all I know about this measure, which is what led me to characterize it as “arbitrary and undocumented”. To believe that all aspects of protocol complexity that might negatively affect enrollment have been adequately captured and weighted in a single 17-point scale requires a leap of faith that I am not, at the moment, able to make. The extraordinary claim that all complexity issues have been accounted for in this model requires extraordinary evidence, and “we conducted a Delphi exercise” does not suffice. 6. All studies funded by NIHR partners were included – we only excluded studies funded without peer review, not won competitively. For the involvement analysis we excluded industry studies because of not being able to contact end users and where inclusion compromised our analysis reliability due to small group sizes. It’s only that last bit I was concerned about. Specifically, the 11 studies that were excluded due to being in “clinical groups” that were too small, despite the fact that “clinical groups” appear to have been excluded as non-significant from the final model of recruitment success. (Also: am I being whooshed here? In a discussion of "questionable math" the authors' enumeration goes from 4 to 6. I’m going to take the miscounting here as a sly attempt to see if I’m paying attention...) I am sure you are aware of the high standing of the journal and its robust peer review. We understand that our results must withstand the scrutiny of other scientists but many of your comments were unwarranted. This is the first in the world to investigate patient involvement impact. No other databases apart from the one held by the NIHR Mental Health Research Network is available to test – we only wish they were. I hope we can agree that peer review – no matter how "high standing" the journal – is not a shield against concern and criticism. Despite the length of your response, I’m still at a loss as to which of my comments specifically were unwarranted. In fact, I feel that I noted very clearly that my concerns about the study’s limitations were minuscule compared to my concerns about the extremely inaccurate way that the study has been publicized by the authors, KCL, and the NIHR. Even if I conceded every possible criticism of the study itself, there remains the fact that in public statements, you Misstated an odds ratio of 4 as “4 times more likely to” Overstated the recruitment success findings as being based on a sample 3 times larger than it actually was Re-interpreted, without reservation, a statistical association as a causal relationship Misstated the difference between the patient involvement categories as being a matter of merely “involving just one or two patients in the study team” And you did these consistently and repeatedly – in Dr Wykes's blog post, in the KCL press release, and in the NIHR-written Guardian article. To use the analogy from my previous post: if a pharmaceutical company had committed these acts in public statements about a new drug, public criticism would have been loud and swift. Your comment on the media coverage of odds ratios is an issue that scientists need to overcome (there is even a section in Wikipedia). It's highly unfair to blame "media coverage" for the use of an odds ratio as if it were a relative risk ratio. In fact, the first instance of "4 times more likely" appears in Dr Wykes's own blog post. It's repeated in the KCL press release, so you yourselves appear to have been the source of the error. You point out the base rate issue but of course in a logistic regression you also take into account all the other variables that may impinge on the outcome prior to assessing the effects of our key variable patient involvement - as we did – and showed that the odds ratio is 4.12 - So no dispute about that. We have followed up our analysis to produce a statement that the public will understand. Using the following equations: Model predicted recruitment lowest level of involvement exp(2.489-.193*8.8-1.477)/(1+exp(2.489-.193*8.8-1.477))=0.33 Model predicted recruitment highest level of involvement exp(2.489-.193*8.8-1.477+1.415)/(1+exp(2.489-.193*8.8-1.477+1.415)=0.67 For a study of typical complexity without a follow up increasing involvement from the lowest to the highest levels increased recruitment from 33% to 66% i.e. a doubling. So then, you agree that your prior use of “4 times more likely” was not true? Would you be willing to concede that in more or less direct English? This is important and is the first time that impact has been shown for patient involvement on the study success. Luckily in the UK we have a network that now supports clinicians to be involved and a system for ensuring study feasibility. The addition of patient involvement is the additional bonus that allows recruitment to increase over time and so cutting down the time for treatments to get to patients. No, and no again. This study shows an association in a model. The gap between that and a causal relationship is far too vast to gloss over in this manner. In summary, I thank the authors for taking the time to response, but I feel they've overreacted to my concerns about the study, and seriously underreacted to my more important concerns about their public overhyping of the study. I believe this study provides useful, though limited, data about the potential relationship between patient engagement and enrollment success. On the other hand, I believe the public positioning of the study by its authors and their institutions has been exaggerated and distorted in clearly unacceptable ways. I would ask the authors to seriously consider issuing public corrections on the 4 points listed above. Full Article NIHR patient recruitment trial delays UK trials
ue Origami Helps Implant Sensors in Bio-Printed Tissue By spectrum.ieee.org Published On :: Thu, 18 Jul 2024 13:00:03 +0000 In the United States alone, more than 100,000 people currently need a lifesaving organ transplant. Instead of waiting for donors, one way to solve this crisis in the future is to assemble replacement organs with bio-printing—3D printing that uses inks containing living cells. Scientists in Israel have found that origami techniques could help fold sensors into bio-printed materials to help determine whether they are behaving safely and properly.Although bio-printing something as complex as a human organ is still a distant possibility, there are a host of near-term applications for the technique. For example, in drug research, scientists can bio-print living, three-dimensional tissues with which to examine the effects of various compounds.Ideally, researchers would like to embed sensors within bio-printed items to keep track of how well they are behaving. However, the three-dimensional nature of bio-printed objects makes it difficult to lodge sensors within them in a way that can monitor every part of the structures.“It will, hopefully in the future, allow us to monitor and assess 3D biostructures before we would like to transplant them.” —Ben Maoz, Tel Aviv UniversityNow scientists have developed a 3D platform inspired by origami that can help embed sensors in bio-printed objects in precise locations. “It will, hopefully in the future, allow us to monitor and assess 3D biostructures before we would like to transplant them,” says Ben Maoz, a professor of biomedical engineering at Tel Aviv University in Israel.The new platform is a silicone rubber device that can fold around a bio-printed structure. The prototype holds a commercial array of 3D electrodes to capture electrical signals. It also possesses other electrodes that can measure electrical resistance, which can reveal how permeable cells are to various medications. A custom 3D software model can tailor the design of the origami and all the electrodes so that the sensors can be placed in specific locations in the bio-printed object.The scientists tested their device on bio-printed clumps of brain cells. The research team also grew a layer of cells onto the origami that mimicked the blood-brain barrier, a cell layer that protects the brain from undesirable substances that the body’s blood might be carrying. By folding this combination of origami and cells onto the bio-printed structures, Maoz and his colleagues were able to monitor neural activity within the brain cells and see how their synthetic blood-brain barrier might interfere with medications intended to treat brain diseases.Maoz says the new device can incorporate many types of sensors beyond electrodes, such as temperature or acidity sensors. It can also incorporate flowing liquid to supply oxygen and nutrients to cells, the researchers note.Currently, this device “will mainly be used for research and not for clinical use,” Maoz says. Still, it could “significantly contribute to drug development—assessing drugs that are relevant to the brain.”The researchers say they can use their origami device with any type of 3D tissue. For example, Maoz says they can use it on bio-printed structures made from patient cells “to help with personalized medicine and drug development.”The origami platform could also help embed devices that can modify bio-printed objects. For instance, many artificially grown tissues function better if they are placed under the kinds of physical stresses they might normally experience within the body, and the origami platform could integrate gadgets that can exert such mechanical forces on bio-printed structures. “This can assist in accelerating tissue maturation, which might be relevant to clinical applications,” Maoz says.The scientists detailed their findings in the 26 June issue of Advanced Science.

ue Bluetooth Microscope Reveals the Inner Workings of Mice By spectrum.ieee.org Published On :: Sun, 13 Oct 2024 13:00:02 +0000 This article is part of our exclusive IEEE Journal Watch series in partnership with IEEE Xplore.Any imaging technique that allows scientists to observe the inner workings of a living organism, in real-time, provides a wealth of information compared to experiments in a test tube. While there are many such imaging approaches in existence, they require test subjects—in this case rodents—to be tethered to the monitoring device. This limits the ability of animals under study to roam freely during experiments.Researchers have recently designed a new microscope with a unique feature: It’s capable of transmitting real-time imaging from inside live mice via Bluetooth to a nearby phone or laptop. Once the device has been further miniaturized, the wireless connection will allow mice and other test subject animals to roam freely, making it easier to observe them in a more natural state.“To the best of our knowledge, this is the first Bluetooth wireless microscope,” says Arvind Pathak, a professor at the Johns Hopkins University School of Medicine. Through a series of experiments, Pathak and his colleagues demonstrate how the novel wireless microscope, called BLEscope, offers continuous monitoring of blood vessels and tumors in the brains of mice. The results are described in a study published 24 September in IEEE Transactions on Biomedical Engineering. Microscopes have helped shed light on many biological mysteries, but the devices typically require that cells be removed from an organism and studied in a test tube. Any opportunity to study the biological process as it naturally occurs in the in the body (“in vivo”) tends to offer more useful and thorough information. Several different miniature microscopes designed for in vivo experiments in animals exist. However, Pathak notes that these often require high power consumption or a wire to be tethered to the device to transmit the data—or both—which may restrict an animal’s natural movements and behavior. “To overcome these hurdles, [Johns Hopkins University Ph.D. candidate] Subhrajit Das and our team designed an imaging system that operates with ultra-low power consumption—below 50 milliwatts—while enabling wireless data transmission and continuous, functional imaging at spatial resolutions of 5 to 10 micrometers in [rodents],” says Pathak. The researchers created BLEscope using an off-the-shelf, low-power image sensor and microcontroller, which are integrated on a printed circuit board. Importantly, it has two LED lights of different colors—green and blue—that help create contrast during imaging. “The BLE protocol enabled wireless control of the BLEscope, which then captures and transmits images wirelessly to a laptop or phone,” Pathak explains. “Its low power consumption and portability make it ideal for remote, real-time imaging.”Pathak and his colleagues tested BLEscope in live mice through two experiments. In the first scenario, they added a fluorescent marker into the blood of mice and used BLEscope to characterize blood flow within the animals’ brains in real-time. In the second experiment, the researchers altered the oxygen and carbon dioxide ratios of the air being breathed in by mice with brain tumors, and were able to observe blood vessel changes in the fluorescently marked tumors. “The BLEscope’s key strength is its ability to wirelessly conduct high-resolution, multi-contrast imaging for up to 1.5 hours, without the need for a tethered power supply,” Pathak says.However, Pathak points out that the current prototype is limited by its size and weight. BLEscope will need to be further miniaturized, so that it doesn’t interfere with animals’ abilities to roam freely during experiments.“We’re planning to miniaturize the necessary electronic components onto a flexible light-weight printed circuit board, which would reduce weight and footprint of the BLEscope to make it suitable for use on freely moving animals,” says Pathak. This story was updated on 14 October 2024, to correct a statement about the size of the BLEscope. Full Article Microscopy Wireless Bluetooth Living cells Journal watch

ue Taiwan businessman Tsao to sue Chinese officials over sanctions By www.asiaone.com Published On :: Mon, 11 Nov 2024 16:32:00 +0800 TAIPEI — Taiwanese businessman Robert Tsao said on Nov 11 that he would sue in a Taiwan court senior Chinese officials over sanctions they had placed on him, saying he was seeking to counter China's intimidation of lawful activity. China, which claims Taiwan as its own territory, said in October it would punish and sanction Tsao, the retired founder of chipmaker United Microelectronics Corp (UMC), for alleged criminal and pro-Taiwan independence activities. China's Taiwan Affairs Office said the "Black Bear Academy" that Tsao has helped fund was seeking to incite separatism that would endanger cross-strait ties.
