Glybera有望成为欧洲首个基因治疗药物 发布时间:2012-7-23 来源:爱唯医学 荷兰生物技术公司uniQure研发的Glybera(alipogene tiparvovec)成为了欧洲首个被推荐上市的基因治疗药物。欧洲药品管理局(EMA)上周五宣布,其人用药品委员会(CHMP)建议在欧盟范围内批准Glybera上市。这一授权将涵盖所有27个欧盟成员国。Glybera为单次注射剂,适用于严格限制脂肪饮食却仍然发生严重或反复胰腺炎发作的脂蛋白脂酶缺乏症(LPLD)患者。CHMP虽然建议批准Glybera上市,但强调这属于“特殊情况”,因此uniQure将需要开展上市后监测,必须建立登记库,监测接受该治疗者的结局,并将数据提交给EMA审查。这项批准令还有待欧盟委员会的最终裁决,但后者通常会采纳CHMP的建议。UniQure期待欧盟委员会在3个月内给出定论。LPLD是一种罕见的严重遗传性疾病,而且目前无法治疗。其发病率约为1~2例/百万人。该病是由LP基因突变引起的,后者会使LPL蛋白的活性严重下降或丧失。LPL蛋白是一种分解乳糜微粒的酶,如果乳糜微粒不被分解,就会在血液中积聚而堵塞小血管,从而可能导致复发性或严重急性胰腺炎。目前,唯一对LPLD患者有帮助的是采取严格限制脂肪饮食,使每日通过脂肪获得的热量不超过总热量的20%。但要坚持这样的饮食习惯并不容易,因此许多患者因危及生命的胰腺炎而住院。基因治疗通过以有活性的基因取代患者DNA中有缺陷的基因而发挥疗效。Glybera利用一种腺相关病毒将有活性的LPL基因插入肌细胞中,从而使这些细胞能产生正常数量的酶。由于LPLD非常罕见,2004年欧盟委员会批准将Glybera列为孤儿药。孤儿药上市申请通常会被更快受理,生产商还会获得经济方面的激励,例如税收优惠和延长市场独占期(在美国为7年,在欧洲为10年)等。不过,Glybera在欧盟的上市之路并非一帆风顺。Glybera的首次申请是在2009年提交的。2011年6月,CHMP和先进治疗委员会(CAT)均表示不赞成该药上市,原因是“他们采纳了关于采用Glybera治疗LPLD的负面意见”。然后Glybera接受了重新审查,CAT表示只要生产商同意开展进一步上市后研究,就有可能批准Glybera批准上市,但CHMP仍坚持其否定意见,直至2011年10月。在2012年1月CHMP召开成员国常务会议之后,欧盟要求EMA重新评估Glybera申请,并且严格限制在严重或反复胰腺炎发作的患者中。在经过详细的学术探讨之后,CAT改变其立场,“于2012年6月采纳了积极的草案意见”,CHMP随后也对此表示支持。CHMP代理主席Tomas Salmonson博士解释称,CHMP的结论是:通过分析符合限制条件的患者的数据,认为Glybera的益处大于已知风险。CAT主席Christian Schneider博士表示,两个委员会虽然存在分歧,但在整个过程中开展了紧密协作。uniQure首席执行官Aldag表示:“CHMP的的支持态度对于LPLD患者和这种药物而言是重大突破。Glybera即将为欧洲治疗孤儿病的首个基因疗法。LPLD患者不敢吃正常的食物以免引起急性胰腺炎和导致急诊入院。如今,这些患者第一次有了治疗方法,不仅能降低出现严重病情的风险,而且只需单次注射即可多年受益。基因治疗将赋予这些患者分解血液中脂肪的能力。”

並不是愛滋病 所有骨人 都可用髓移植 根除HIV病毒!!
治療愛滋病 科學家趨樂觀【中央社╱華盛頓22日綜合外電報導】 2012.07.23 04:25 pm 第19屆國際愛滋病研討會今天在華府揭幕,會期6天,到27日為止。科學家呼籲各界投入資源,進一步尋求治癒愛滋病的良方,並表示愛滋病流行可能在40年內控制住。因罹患後天免疫不全症(AIDS)而在2011年死亡的有150萬人,專家呼籲全球加緊採取行動,對抗這個發現了30年的傳染病。這項世界最大的愛滋病會議預期會吸引政治人物、科學家、運動人士等2萬5000人與會,若干愛滋病患也會親自講述自己的故事。全球估計有3400萬人罹患愛滋病。其中一名是美國人布朗(Timothy Brown),他經由骨髓移植成為世界第一個達到「功能性治癒」的愛滋病患。布朗將於24日發表演說,希望宣揚治療愛滋病的新努力。布朗在柏林接受治療,醫療人員先破壞他的免疫系統,再讓他接受幹細胞移植,捐贈者帶有罕見基因變異,對愛滋病毒免疫。但這項手術所費不貲,且難以複製、大規模施行。自從布朗在2007年功能性治癒後,他的病例讓科學家認為,現在正是找出愛滋病解藥的時機。這項愛滋病會議每兩年召開一次,這是1990年以後首度回到美國召開,因為美國2009年取消了禁止愛滋病患入境美國的法令。這屆會議的主題是「力挽狂瀾」。諾貝爾醫學獎得主巴瑞-西諾希(FrancoiseBarre-Sinoussi)指出,科學家正盡全力找出愛滋治癒之道。巴瑞-西諾希因所屬團隊發現導致愛滋病的人類免疫不全病毒(HIV),2008年獲頒諾貝爾醫學獎。她以「柏林病患」布朗似乎透過骨髓移植而痊癒來說:「這證明確實有可能找到根除病毒之道。」她指出,藥物普及度的障礙若能去除,愛滋流行「原則上」可能於2050年前絕跡。慈善家比爾‧蓋茲(Bill Gates)承諾捐獻25億美元愛滋病基金給世界各地相關組織。他說:「我們有許多進展,可能扭轉大局,讓我們一步步趨近愛滋病的終結。」他指的是新疫苗、抗反轉錄病毒藥物等協助愛滋病患對抗疾病的進展。「我很樂觀…我們會發展出新工具…將使愛滋病成為陳跡。攜手合作,我曉得我們能達成目標。」國際科學家數日前在英國「自然」(Nature)期刊發表一項計畫,推動新一波愛滋病治癒方法。這項7步驟的科學策略著重在關鍵領域,像是愛滋病毒在人體的藏身處,以及全球各地似乎對愛滋病毒有天然抵抗力的少數人。聯合國呼籲,2015年以前每年投入220億至240億美元協助抑制愛滋病,其中70%的經費會用在最嚴重地區的抗反轉錄病毒治療上。【2012/07/23 中央社】

Gut Microbes Might Reflect Health !!!!
Diet of Older Adults Study found intestinal species varied depending on
seniors' health, residence Friday, July 13, 2012 FRIDAY, July 13 (HealthDay
News) -- The health of elderly people appears closely linked with their diet
and the type of microorganisms living in their gut, suggesting that what you
eat may affect how well you age, according to new research. "Our findings
indicate that any two given older people, independent of [their] starting
health status and genetic makeup, could experience very different rates of
health loss upon aging due to dietary choices that impact on their gut
bacterial ecosystem," said Paul O'Toole, senior author of the study
appearing July 13 in the
journal Nature. "You can think of [diet] as another controllable
environmental factor that we can act upon to promote healthier aging,"
O'Toole added. Numerous studies have indicated a link between the
"microbiota" that live in the human gut and health, including obesity
and perhaps even brain health. More recent studies have noted greater variation
in the microbiota of elderly people than younger people. To study the potential
meaning of this greater variation, these authors looked at the gut microbiota
of 178 elderly individuals (average age 78). None was being treated with
antibiotics, which can alter the composition of your gut. The researchers
discovered that intestinal flora (microbes) varied depending on where the
participants lived and also with their health. For instance, people living
independently in the community had more varied flora and were the healthiest. On
the other hand, people living in long-term, assisted-living situations had less
diverse flora and tended to be frailer. The differences in flora were
associated with differences in diet, although it's unclear if the diet was
responsible for the number and type of flora and health status or the other way
around. It does seem likely that it's diet that ultimately determines a
person's health status, the authors stated. "The diet of older people
changes quickly when they move from community to long-term care (in a couple of
weeks), but the microbiota changes more slowly -- up to a year for full change
from community type to long-term residential type," O'Toole explained.
"One would not expect that the rate of heath decline in this time could be
responsible for the change in microbiota composition. It's more plausible to be
driven by diet." A September 2011 study in the journal Science found that
people who ate a diet high in fats and animal proteins had a different
assortment of bacteria in their digestive tracts than people who ate a diet
with more plant-based foods and higher carbohydrates. Identifying exactly what
lives in our guts could point to dietary interventions that might lead to
longer and healthier lives, authors of the new study stated. "To combat
frailty, it makes sense if our microbiota is helping our bodies to be as
effective and efficient as possible," said O'Toole, a senior lecturer in
genetics at University College Cork, in Ireland . Gut microbiota synthesizes
vitamins, helps metabolism and appears also to profoundly affect how our immune
systems work. "[Some studies] have shown that gut bacteria can 'talk' to
the brain by synthesizing compounds that affect the brain-gut axis,"
O'Toole said. "An exciting theory is that altered gut bacteria in older
subjects could impact on cognitive function or mood." Gastroenterologist
Dr. Ilseung Cho commented on the findings. "This is one of the first
studies that correlates differences in the gut microbiome to disease in the
elderly. It remains to be seen whether the observed differences are a result or
cause of infirmity in this particular population," said Cho, an assistant
professor of medicine at NYU Langone Medical
Center , in New York City . "Regardless, these
findings add to the growing body of evidence that shows that the gut microbiome
can affect human health and disease at all stages of life," Cho added. Dr.
David Bernstein, a gastroenterologist and chief of hepatology at North
Shore-LIJ Healthcare System, in Manhasset ,
N.Y. , considers the findings
preliminary. "We know that there are millions or billions of bacteria
throughout the gut, and how we manipulate those certainly affects health,"
said Bernstein, who is also a professor of medicine at Hofstra-North Shore LIJ
School of Medicine. "This is an important topic [but] it requires a lot
more research," Bernstein said. SOURCES: Paul O'Toole, Ph.D., senior

Biosimilar regulations and CMOs
WEBINAR: JUNE 26 | 11AM ET/8 AM
PT Biosimilar legislation passed in 2010 guaranteed 12 years of patent
protection to biotechs from biosimilar competition. But passing the law was the
easy part. As FDA hashes out regulations to implement the law, we help CMOs
understand the significance of the legislation to their businesses and how the
new legislation may help, or hurt, contract manufacturing for biologics.

drug giant, which currently lacks a big cardio business, seeks its first
multibillion-dollar seller in this category. In May the drugmaker wrote off its
experimental dalcetrapib after the drug for increasing good cholesterol bombed
in a late-stage study. As Bloomberg reports, Roche has kept details about its
PCSK9 drug from U.S.
unit Genentech under wraps because of the intense competition in the field. Yet
that will rapidly change as Roche unveils data on the program and builds its
case with docs to enroll their patients in its studies. Behind Roche's and
Sanofi's PCSK9 programs are several more. Amgen ($AMGN) and Pfizer are in
mid-stage studies with their own candidates aimed at the hot target. Also,
Bristol-Myers Squibb ($BMY), Merck ($MRK) and Alnylam ($ALNY) have research
underway in the field. "These drugs allow us to go where no one has gone
before," Steven Nissen, chairman of the Department of Cardiovascular
Medicine at the Cleveland Clinic in Ohio ,
said in an interview with Bloomberg. "There's a tremendous amount of
interest among a broad range of makers of pharmaceuticals to get
involved."

Placenta-derived endothelial colony-forming cells are more vasculogenic
Published on July 20, 2012 at
1:14 PM · No Comments A study comparing whether endothelial colony-forming
cells (ECFCs) derived from human placenta or those derived from human umbilical
cord blood are more proliferative and better for forming new blood vessels has
found that ECFCs derived from human placenta are more vasculogenic. The study,
carried out by researchers at the Indiana School of Medicine, is published in a
recent issue of Cell Medicine [2(3)] and is freely available on-line at:
http://www.ingentaconnect.com/content/cog/cm. "Circulating ECFCs isolated
from umbilical cord blood and those isolated from human placenta are
phenotypically identical and have equivalent proliferative potential,"
said study lead author Michael P. Murphy, MD of the Indiana University 's
Department of Surgery. "After transplantation, the circulating
placenta-derived ECFCs formed significantly more blood vessels in vivo than the
ECFCs derived from umbilical cord blood, indicating not only that there are
inherent functional differences between resident and circulating ECFC
populations, but that the placenta-derived cells are more vasculogenic." Umbilical
cord blood and the extra-embryonic membranes of placenta are ideal sources of
progenitor cells, said the researchers, because the tissues are discarded as
medical waste and ethical concerns facing embryonic stem cells are avoided. The
quantity of cells that can be derived from placenta, however, is much greater
than the amount that can be derived from umbilical cord blood, making the
placenta the more abundant source.

Music has big brain benefits compared to other leisure pursuits
July 20, 2012 in Neuroscience Musical instrumental training,
when compared to other activities, may reduce the effects of memory decline and
cognitive aging (Medical Xpress) -- It turns out mom was right. Music lessons
are good for you, and those benefits may last a lifetime. A recent study
conducted by Brenda Hanna-Pladdy, PhD, a clinical neuropsychologist in Emory
University School of Medicine’s Department of Neurology, offers additional
evidence that musical instrumental training, when compared to other activities,
may reduce the effects of memory decline and cognitive aging. This is the
second study published by Hanna-Pladdy, which confirms and refines findings
from an original study published in Neuropsychology in 2011 that revealed that
musicians with at least 10 years of instrumental musical training remained
cognitively sharp in advanced age. The findings were published in the July
issue of Frontiers in Human Neuroscience. “The study confirms that musical
activity preserves cognition as we age, by comparing variability in cognitive
outcomes of older adults active in musical instrumental and other leisure
activities,” says Hanna-Pladdy. “A range of cognitive benefits, including
memory, was sustained for musicians between the ages of 60-80 if they played
for at least 10 years throughout their life, confirming that maintenance of
advantages is not reliant on continued activity. In other words, you don’t use
it or lose it. Nonetheless, the study highlighted the critical importance of
the timing of musical activity, which may optimize cognitive benefits.” The
cognitive enhancements in older musicians included a range of verbal and
nonverbal functions, as well as memory, which is the hallmark of Alzhemier’s
pathology. The study evaluated the timing of musical engagement to determine
whether there is a critical period of musical training for optimal cognitive
advantages in advanced age. While years of playing music were the best
indication of enhanced cognition in advanced age, the results revealed
different sensitive periods for cognitive development across the lifespan. Early
age of acquisition, before age nine, predicted verbal working memory functions
such as remembering and reorganizing digits in your head, consistent with early
sensitive periods in brain development. Sustained musical activity in advanced
age predicted other non-verbal abilities involving visuospatial judgment,
suggesting it is never too late to be musically active. Continued musical
activity in advanced age also appeared to buffer lower educational levels. “This is an exciting finding in light of recent evidence suggesting that
high educational levels are likely to yield cognitive reserve that may
potentially delay the onset of Alzheimer’s symptoms or cognitive decline,” says
Hanna-Pladdy. “This also highlights the promising role of musical activity as a
form of cognitive enrichment across the lifespan, and it raises the question of
whether musical training should eventually be considered an alternative form of
educational training.” According to Hanna-Pladdy, to obtain optimal results,
individuals should start musical training before age nine, play at least 10
years or more and if possible, keep playing for as long as possible over the
age of 60. Music rocks. Musical activity was found to preserve cognition,
including memory, as you age, when comparing variability in cognitive outcomes
of older adults active in musical instrumental and other leisure activities.
You won’t lose it if you don’t use it. A range of cognitive benefits including
memory were sustained for musicians between the ages of 60-80 if they played
for at least 10 years throughout their life, confirming the maintenance of
advantages is not reliant on continued activity. Start young. Timing of musical
instrumental acquisition, before age nine, is important in optimizing cognitive
benefits and was associated with enhanced verbal working memory functions. It’s
never too late, so keep at it. Sustained musical activity over the age of 60
was associated with other nonverbal cognitive benefits, and appeared to compensate
for low educational attainment, which is possibly the greatest protection
against age-related cognitive declines. This suggests that musical training
should be considered an alternative form of education. Journal reference:

王榮旭:生技股 醞釀大爆發【經濟日報╱】 2012.07.23 04:46 am 歐洲消費緊縮,全球經濟跟著降溫,各國央行降息救市,提振經濟還需時間發酵,此時景氣打底階段,各產業都受到波及,上周電子股受創嚴重,除生活必須品外,就屬生技最強。事實上,生技向來與景氣連動性低,國際大藥廠如製造銷售醫療保健產品的嬌生(JNJ)與全球最大製藥公司輝瑞(PFE)上周股價皆創近4年來新高,國際大型製藥、新藥研發公司必治妥(BMY)上周更是創下10年來新高股價,不僅如此,中國的廣州藥業(600332)7月以來大漲35%,股價改寫歷史新高。要不是台股太弱,台灣生技股應該不止漲這樣。台灣生技產業坐擁「天時、地利、人和」,過去研發的新藥在未來2~3年內就會有成功上市的機會,地理位置與14億人口的中國市場緊鄰,在語言上比歐美亞洲鄰國更具有優勢,因此,更能掌握到中國十二五生醫升級的商機。此外,生技鑽石起飛計畫重新啟動,顯示政府的積極態度,若能更進一步擴大ECFA的加乘效果,把進入中國市場的時間縮短及降低門檻,那肯定會讓台灣生技大爆發,生技股已經朝這個方向前進,如新藥股基亞,去年底剛掛牌沒沒無聞,經過一段時間後,股價從不到30元飆漲到70元,跌破大家眼鏡。到現在我看好基亞的立場沒變,因為其新藥價值高,才能獲選成為兩岸新藥合作試範廠商,跳過臨床1、2期,直接到大陸進行3期臨床,完成3期臨床後就可申請藥證上市銷售,股價維持高姿態整理,後勢不要小看。至於已經先到中國搶占市場的F-金可則已經開花結果,穩居中國隱形眼鏡市場龍頭,如今回攻台灣市場,進入暑假旺季與精華大力促銷,第3季營收可望改寫歷史新高。本周生技展前,生技股王精華股價愈走愈高,比價效應又再展開,東洋微脂體可望獲國際大廠代工訂單,營運大有轉機,轉投資新藥股智擎預計8月掛牌,潛在投資利益可觀。進軍中國原料藥市場的神隆,下半年業績也很有看頭,台灣兩條新產線即將完工,估可增加三成新產能,在中國擁有符合新版GMP規範的藥廠,未來可望成為中國癌症原料藥龍頭,其美國客戶Vivus減肥新藥獲FDA藥證,這是13年以來FDA「唯二」被核准有關調整體重的新藥,預估第4季上市銷售量將很可觀,其原料藥由神隆獨家供應,第3季出貨量就會增溫,股價完成中期頭肩底,上周突破所有均線,法人大買,為一檔下有撐、上無壓的生技潛力股。(作者是萬寶投顧證券期貨雙證分析師)【2012/07/23 經濟日報】

3-D tumor models improve drug discovery success rate
July 20, 2012 in
Medications Imagine millions of cancer cells organized in thousands of small
divots. Hit these cells with drugs and when some cells die, you have a
candidate for a cancer drug. But a review published this week in the journal
Expert Opinion on Drug Discovery argues that these 2D models in fact offer very
little information about a potential drug's effects in the body and may often
give researchers misleading results. "Up until the 1980s animal models
were the standard for cancer drug discovery. However, with the increase in the
number of compounds available for testing and the advent of high-throughput
screening (HTS), the use of animals to discover cancer drugs became too costly
and unethical. Consequently, 2D cell culture models have become the mainstay
for drug discovery or to explore a drug's mechanism of action," says Dan
LaBarbera, PhD, investigator at the University of Colorado Cancer Center and
the University of Colorado Skaggs School of Pharmacy and Pharmaceutical
Sciences. LaBarbera is principal investigator of the recent review, on which he
collaborated with Skaggs colleagues Brian Reid, PhD, and Byong Hoon Yoo, PhD.
LaBarbera cites the gap between results in 2D cells and effects in tumors
themselves as a contributing factor for the declining rate of drugs passing FDA
approval. In particular, only 5 percent of investigational new drugs targeting
cancer make it through clinical trials, at a cost of about $800 million per
drug. When you factor in the inevitable failures at various points in
development, each approved drug costs an average $1.5 billion. To increase the
drug success rate, LaBarbera suggests something called the multicellular tumor
spheroid (MCTS) model. In these models, instead of 2D monolayers, cancer cells
are cultured as 3D spheroids. One of the advantages of the MCTS model is that
when spheroids reach a critical diameter, they begin to form an outer
proliferating zone, an inner quiescent zone, and a central necrotic core – more
faithfully mimicking the microenvironments of human tumors. Additionally,
spheroids can be grown in the presence of compounds that mimic extra cellular
matrix – the environment that surrounds and very much affects the growth and
behaviors of human tumors. Why pay more? Save on Quality Monoclonal Antibodies
& much more! - www.anogen.ca Instead of indiscriminately killing cells,
modern cancer drugs tend to target cells with very specific genetic mutations
that turn on and off very specific growth and survival mechanisms that in turn
very frequently depend on everything else going on in and around the cells.
Using MCTS models, researchers can ask questions about how a drug will
penetrate a tumor's heterogeneous 3D structure and how a drug will interact
with the environment surrounding these tiny tumors. "Though these MCTS
models have been around since the 1970s, only recently has technology made it
possible to use them in place of 2D models for the high-throughput screening
used in drug discovery," LaBarbera says. Remember those millions of cancer
cells organized in independent divots that researchers hit with drugs? We're
fairly tied to the technology that reads the results of these divots. But
micro-technologies now allow multicellular tumor spheroids to be cultured in
place of 2D cell cultures using high-throughput micro-well plates – we can use
the same drug testing machinery on these new models. Likewise, materials
science technology now exists to grow cells within semipermeable membranes,
helping researchers define the shape of the eventual spheres. And as futuristic
as it undoubtedly sounds, magnetic cell levitation can help alleviate the
problem of cells sticking to the plastic well surface, which limits spheroid
growth. The recent practicality of high-throughput MCTS screening leads
LaBarbera to call today a "renaissance" for the technique. Of course,
this 3D testing is initially more expensive and more challenging. "A lot
of researchers try to get cost down to pennies per well – you can see how
screening millions of compounds equals millions of dollars – but this often
leads to a higher cost down the road due to a lower success rate. Yes, it may
cost more to do HTS with 3D models, but in the long run it may lead to higher
success rates and so decreased costs," LaBarbera says. LaBarbera suggests
that another use of the systems biology approach made possible by 3D models
like MCTS is to bridge the gap between high-volume, low-accuracy screens and
more involved testing in animal models. "We envision a future in which
MCTS arrays enable a convergence of systems biology and chemical biology,
improving the success rate of drugs in the pipeline of discovery,"
LaBarbera says. Provided by University
