一項(xiàng)最新研究發(fā)現(xiàn),糖尿病藥物Mounjaro中的藥物成分,在與嚴(yán)格的膳食控制和大量運(yùn)動(dòng)相結(jié)合的情況下,有望幫助那些肥胖癥患者或超重者平均減輕四分之一的體重,平均減重約60磅。
研究團(tuán)隊(duì)于上周日在《自然醫(yī)學(xué)》雜志上披露,與對(duì)照組相比,另一組參與者同樣進(jìn)行了飲食限制和體育鍛煉,但他們服用的是安慰劑。盡管一開始他們也經(jīng)歷了體重減輕,但隨后有所反彈。
賓夕法尼亞大學(xué)(University of Pennsylvania)肥胖研究與心理學(xué)教授、該項(xiàng)研究的負(fù)責(zé)人托馬斯·瓦登博士表示:“研究表明,如果你在開始服用藥物之前減重,那么服藥之后體重還能進(jìn)一步下降?!?/p>
上周日召開的一次醫(yī)學(xué)會(huì)議也公布了該研究的結(jié)果。有外部專家表示,研究結(jié)果表明,禮來公司(Eli Lilly & Co.)開發(fā)的藥物,有潛力成為迄今為止最強(qiáng)大的治療肥胖癥的藥物。
在布里格姆婦科醫(yī)院從事肥胖癥治療的卡洛琳·阿普韋恩博士表示:“無論如何計(jì)算,它的減肥效果都能達(dá)到你總體重的四分之一?!卑⑵枕f恩并未參與該項(xiàng)研究。
研究所涉及的注射用藥替爾泊肽(tirzepatide),于2022年5月被美國批準(zhǔn)用于治療糖尿病。這款藥物的商品名為Mounjaro,它一直被用作治療肥胖癥的“適應(yīng)癥外藥物”。與諾和諾德公司(Novo Nordisk)生產(chǎn)的Ozempic和Wegovy等糖尿病與減肥藥物一樣,Mounjaro同樣很受歡迎,需求高漲。
這些藥物每個(gè)月用量的零售價(jià)高達(dá)900美元甚至更高,已經(jīng)連續(xù)數(shù)月短缺。
替爾泊肽作用于兩種激素,這兩種激素在人們進(jìn)食后發(fā)揮作用,它們可以調(diào)節(jié)食欲和飽腹感,還在腸道和大腦之間傳遞信號(hào)。而在Ozempic和Wegovy中使用的成分,司美格魯肽,則專門作用于其中一種激素。
這項(xiàng)最新研究得到了禮來的資助。研究招募了約800名肥胖癥患者或超重者,參與者存在與體重有關(guān)的健康并發(fā)癥,但均沒有糖尿病。參與者在研究開始時(shí)的平均體重約為241磅(109.5公斤),平均體重指數(shù)(衡量肥胖癥的常用指標(biāo))約為38。
經(jīng)過三個(gè)月的嚴(yán)格飲食和大量運(yùn)動(dòng),共有200多名參與者由于體重減輕不明顯或其他原因提前退出了試驗(yàn)。剩下的近600人被隨機(jī)分為兩組,分別接受替爾泊肽或者安慰劑,每周注射一次。最終,近500人完成了研究。
兩組參與者在節(jié)食和運(yùn)動(dòng)階段均減重約7%,約為17磅(8公斤)。服用藥物的參與者平均額外減少原始體重的18.4%,約為44磅(20公斤)。服用安慰劑的參與者體重反彈了6磅(2.7公斤),約為原始體重的2.5%。
有88%替爾泊肽組參與者,在試驗(yàn)期間減重5%或以上,相比之下,安慰劑組參與者達(dá)到這個(gè)減重效果的比例只有約17%。約29%的用藥組參與者至少減少了原始體重的四分之一,而安慰劑組的比例略高于1%。
阿普韋恩表示,這個(gè)比例高于司美格魯肽的試驗(yàn)結(jié)果,與減肥手術(shù)的效果接近。
她說道:“這相當(dāng)于一種胃旁路手術(shù)?!?/p>
服用替爾泊肽的參與者比安慰劑組更頻繁地經(jīng)歷惡心、腹瀉、和便秘等副作用。然而,研究發(fā)現(xiàn)這些副作用主要是輕度至中度,并且主要出現(xiàn)在劑量增加后。超過10%的用藥組參與者因?yàn)楦弊饔枚袛嗔嗽囼?yàn),而安慰劑組的中斷比例約為2%。

The medicine in the diabetes drug Mounjaro helped people with obesity or who are overweight lose at least a quarter of their body weight, or about 60 pounds on average, when combined with intensive diet and exercise, a new study shows.
By comparison, a group of people who also dieted and exercised, but then received dummy shots, lost weight initially but then regained some, researchers reported Sunday in the journal Nature Medicine.
“This study says that if you lose weight before you start the drug, you can then add a lot more weight loss after,” said Dr. Thomas Wadden, a University of Pennsylvania obesity researcher and psychology professor who led the study.
The results, which were also presented Sunday at a medical conference, confirm that the drug made by Eli Lilly & Co. has the potential to be one of the most powerful medical treatments for obesity to date, outside experts said.
“Any way you slice it, it’s a quarter of your total body weight,” said Dr. Caroline Apovian, who treats obesity at Brigham and Women’s Hospital and wasn’t involved in the study.
The injected drug, tirzepatide, was approved in the U.S. in May 2022 to treat diabetes. Sold as Mounjaro, it has been used “off-label” to treat obesity, joining a frenzy of demand for diabetes and weight-loss medications including Ozempic and Wegovy, made by Novo Nordisk.
All the drugs, which carry retail price tags of $900 a month or more, have been in shortage for months.
Tirzepatide targets two hormones that kick in after people eat to regulate appetite and the feeling of fullness communicated between the gut and the brain. Semaglutide, the drug used in Ozempic and Wegovy, targets one of those hormones.
The new study, which was funded by Eli Lilly, enrolled about 800 people who had obesity or were overweight with a weight-related health complication — but not diabetes. On average, study participants weighed about 241 pounds (109.5 kilograms) to start and had a body-mass index — a common measure of obesity — of about 38.
After three months of intensive diet and exercise, more than 200 participants left the trial, either because they failed to lose enough weight or for other reasons. The remaining nearly 600 people were randomized to receive tirzepatide or a placebo via weekly injections for about 16 months. Nearly 500 people completed the study.
Participants in both groups lost about 7% of their body weight, or almost 17 pounds (8 kilograms), during the diet-and-exercise phase. Those who received the drug went on to lose an additional 18.4% of initial body weight, or about 44 pounds (20 kilograms) more, on average. Those who received the dummy shots regained about 2.5% of their initial weight, or 6 pounds (2.7 kilograms).
Overall, about 88% of those taking tirzepatide lost 5% or more of their body weight during the trial, compared with almost 17% of those taking placebo. Nearly 29% of those taking the drug lost at least a quarter of their body weight, compared with just over 1% of those taking placebo.
That’s higher than the results for semaglutide and similar to the results seen with bariatric surgery, said Apovian.
“We’re doing a medical gastric bypass,” she said.
Side effects including nausea, diarrhea and constipation were reported more frequently in people taking the drug than those taking the placebo. They were mostly mild to moderate and occurred primarily as the dose of the drug was escalated, the study found. More than 10% of those taking the drug discontinued the study because of side effects, compared with about 2% of those on placebo.
Lilly is expected to publish the results soon of another study that the firm says shows similar high rates of weight loss. The U.S. Food and Drug Administration has granted the company a fast-track review of the drug to treat obesity, which Eli Lilly may sell under a different brand name. A decision is expected by the end of the year.
