Are there randomized trials of GLP-1 weight-loss drugs in Asian populations?

Yes.[F1][F2][F3][F4][F5][F9] The five trials checked here cover China, Japan, South Korea, Hong Kong, and Thailand, with STEP 7 additionally including Brazil; the results apply only under each trial's own conditions.[F1][F2][F3][F4][F5][F9]

Would the effect differ for people in Taiwan?

Unknown.[F12][F13] SELECT, SURMOUNT-1, and SURMOUNT-OSA have Taiwanese enrolment sites, but the published abstracts and registry results do not separately list a Taiwanese efficacy estimate; enrolment is not the same as an existing subgroup analysis.[F12][F13]

How large were the five Asian trials?

The randomized samples were 210, 267, 401, 375, and 150; the study populations and designs differ, so the figures cannot be merged into a single effect.[F1][F2][F3][F4][F5][F10]

Why compare against the global studies?

SURMOUNT-1's 2,539 and SELECT's 17,604 give a sense of the scale of evidence, and both list Taiwanese sites; but a global overall result still cannot substitute for a Taiwanese subgroup estimate.[F6][F7][F12][F13]

Can the Chinese trial stand in for Taiwan's approved population?

No.[F1][F8] SURMOUNT-CN used a BMI of at least 28, or at least 24 with a comorbidity; Taiwan's Mounjaro conditions are at least 30, or 27 to under 30 with a comorbidity.[F1][F8]

Can enrolment location be determined from the authors' addresses?

It cannot.[F12][F13] The earlier version missed Taiwan precisely because it searched author institutions; the trial registration's locations field is what should be checked, because an author's institution is not an enrolment site.[F12][F13]

Who sponsored these core trials?

The two Asian tirzepatide trials cited here list Eli Lilly, and the three Asian semaglutide trials plus SELECT list Novo Nordisk.[F1][F2][F3][F4][F5][F7]

What kind of data would narrow the Taiwanese evidence gap?

Actual Taiwanese enrolment counts, arm assignments, Taiwan-stratified results, and a pre-specified national or regional interaction with confidence intervals; a well-designed Taiwanese local cohort study could additionally address real-world care questions.[F10][F13]

Can GLP-1 Weight-Loss Trials Be Applied Directly to People in Taiwan? Taiwanese Sites Enrolled, Still No Taiwanese Subgroup Data

Randomized trials of tirzepatide or semaglutide have been run in China, Japan, South Korea, Hong Kong, and Thailand, establishing that these drugs produce a mean difference in body weight in the Asian populations those studies enrolled.[F1][F2][F3][F4][F5] The more important correction is this: the `locations` field on ClinicalTrials.gov shows Taiwanese sites listed for SELECT, SURMOUNT-1, and SURMOUNT-OSA, while SURMOUNT-5 and the negative control FLOW have none.[F12] The earlier version of this article wrongly stated that Taiwan was not enrolled because the original investigation searched the institutional affiliations of paper authors rather than the enrolment sites in the trial registration.[F12][F13] The honest answer now has two layers: **the registry lists Taiwanese trial centres**[F12]; but **the registry does not disclose how many people each centre actually enrolled, and the published results are not broken down by country**, so neither "how many people in Taiwan were actually enrolled" nor "how well it works for people in Taiwan" can be answered from public data[F13][F14]. Establishing whether the effect in Taiwan differs would require the actual Taiwanese enrolment numbers, group assignments, results, and a pre-specified regional interaction analysis.[F13]

On the left of a desk lies a sheet carrying only soft washes of pale green and blue-grey, with no recognisable landform; several brass pins stand upright in the wash. On the right, a bound notebook lies open, both pages completely blank and the brightest area in the picture. — Trial sites in Taiwan enrolled patients, but no separate subgroup data for the Taiwan population exists.

The honest answer has changed: Taiwanese sites enrolled, but the Taiwanese subgroup effect is still unknown

East and Southeast Asia do have randomized trials of tirzepatide and semaglutide, but what these studies answer is the mean effect within their own enrolment sites, thresholds, follow-up periods, and analysis populations.[F1][F2][F3][F4][F5] The five regional trials this article originally selected have no Taiwanese sites, but that cannot support an inference that no relevant trial includes Taiwan. Checking the `locations` field of the five global trials selected here, one by one, shows Taiwanese enrolment sites listed for SELECT, SURMOUNT-1, and SURMOUNT-OSA, with SURMOUNT-5 and FLOW doubling as negative controls.[F9][F12] This is a check of the selected items, not a complete inventory of every relevant global trial.[F12]

So the first correction is this: the registry does list Taiwanese trial centres[F12], rather than the originally assumed "Taiwan was not included at all". But the scope of that correction has to be stated precisely — listing a centre is not the same as having enrolled anyone there: the registry's location field contains only city, institution, and postal code, with no per-centre enrolment count[F14]. Whether the effect differs for people in Taiwan remains: unknown.[F13] That "unknown" arises because the published results give estimates only for the overall treatment groups, without separately listing Taiwanese enrolment numbers, Taiwanese results by arm, confidence intervals, or a treatment-by-region interaction.[F13] Nationality, enrolment location, care setting, diet, comorbidities, treatment persistence, and trial thresholds may all be entangled; a global average, or the phrase "Asian people", cannot pull them apart.[F10][F13]

The cause of the earlier error also belongs on the record: the original investigation searched the institutional addresses of paper authors, not the enrolment sites in the trial registration.[F12][F13] An author may be responsible for design, analysis, or writing, and an author's institution is not an enrolment site; determining which countries participated requires reading the registry's `locations` field.[F12] The question is therefore now split into three layers: whether the drug is effective in the specific Asian trial populations, whether the registry lists Taiwanese trial centres, and whether public data can identify a Taiwan-specific effect.[F1][F12][F13] The first two layers have answers. The last still has an evidence gap — and the answer at the location layer reaches only as far as "centres are listed", not "this many people were enrolled"[F14].

One more thing has to be written out: SURMOUNT-CN carries a published erratum. That erratum is titled Errors in Figure, Results, and End Matter, published in JAMA 2024, volume 332, page 595[F15]. The erratum record itself contains no correction content, so we cannot determine whether it touched the figures cited here, and we will not claim that it had no effect. What can be confirmed is that the 210 participants, −13.6%／−17.5%／−2.3%, and week 52 cited here match the current abstract verbatim as of the verification date[F15]. Establishing what the erratum changed requires obtaining the journal's full erratum text.

What the five Asian trials actually measured

SURMOUNT-CN ran at 29 study sites in China, with 210 people randomized; mean weight change at week 52 was −13.6% in the tirzepatide 10 mg group, −17.5% in the 15 mg group, and −2.3% on placebo.[F1] It enrolled adults without diabetes who had a BMI of at least 28, or at least 24 with one or more weight-related comorbidities.[F1]

SURMOUNT-J ran at 18 study sites in Japan, with 267 people randomized; because one study site was excluded, the modified intention-to-treat set was 225.[F2] Mean weight difference against placebo at week 72 was −16.1 and −21.1 percentage points for tirzepatide 10 mg and 15 mg respectively.[F2] Its enrolment criteria were a BMI of at least 27 with two or more obesity-related conditions, or at least 35 with one or more, excluding diabetes.[F2]

STEP 6 ran at 28 study sites in Japan and South Korea, randomizing 401 people in total.[F3] At week 68, semaglutide 2.4 mg gave a mean weight change of −13.2%, the 1.7 mg arm −9.6%, and placebo −2.1%.[F3] STEP 7 enrolled 375 people at 23 study sites across China, Hong Kong, Brazil, and South Korea; at week 44, semaglutide 2.4 mg gave a mean change of −12.1% and placebo −3.6%.[F4]

STEP 11 enrolled 150 people at 12 study sites in South Korea and Thailand, all without diabetes and with a BMI of at least 25.[F5] At week 44, semaglutide 2.4 mg gave a mean weight change of −16.0% and placebo −3.1%; 96% and 25% respectively achieved at least a 5% reduction.[F5] These figures establish group means and threshold proportions under each trial's own protocol. They cannot be treated as a prediction for any individual user in Taiwan.[F10]

How far the Asian samples are from the global pivotal studies

An open field under a soft sky: on the left, a small cluster of about a dozen figures; on the right, a vast crowd of figures receding into the distance — same ground, same light, wildly different scale. — The sample sizes for the two populations differ by one to two orders of magnitude, so their statistical weight is not equal.

The randomized samples of the five Asian trials are 210, 267, 401, 375, and 150.[F1][F2][F3][F4][F5] For scale, the global SURMOUNT-1 randomized 2,539 people and SELECT randomized 17,604.[F6][F7] Against those two global studies, the smaller Asian trials differ in sample size by roughly 6-fold to 117-fold, spanning close to one to two orders of magnitude.[F10]

A smaller sample does not make a study invalid, and quality cannot be judged by headcount alone.[F10] Randomization still supports the treatment comparison within each trial; what is genuinely limited is precision for less common outcomes, the stability of subgroup analyses, and how much information remains once results are sliced down to a single region.[F10] SELECT's 17,604 people primarily answer cardiovascular outcomes in people with established cardiovascular disease who are overweight or obese and do not have diabetes; even though SELECT lists Taiwanese sites, its overall global result cannot simply be relabelled as a Taiwanese subgroup effect.[F7][F12][F13]

This comparison exists to calibrate the quantity of evidence, not to merge different questions into a single league table.[F10] SURMOUNT-CN, SURMOUNT-J, STEP 6, STEP 7, and STEP 11 differ in sites, BMI thresholds, treatment duration, molecule, and endpoints; subtracting five percentages from one another destroys the randomized comparison each was built on.[F1][F2][F3][F4][F5][F10]

The Chinese trial's thresholds and Taiwan's approval conditions are not the same population

Two wooden doorframes stand freestanding on grass, side by side, built to noticeably different heights; a person stands between them, able to pass through only one. — Different diagnostic or enrollment thresholds end up selecting for different populations altogether.

SURMOUNT-CN's enrolment threshold was a BMI of at least 28, or at least 24 with at least one weight-related comorbidity.[F1] The weight-management conditions recorded in Taiwan's government drug data for Mounjaro are an initial BMI of at least 30, or 27 to under 30 with at least one weight-related comorbidity.[F8] The two sets of thresholds are plainly different, so the full enrolled population of the Chinese trial cannot be written up as the same group of people covered by Taiwan's approval conditions.[F1][F8]

That mismatch bears directly on extrapolation.[F10] For instance, someone with a BMI of 24 to under 27 and a comorbidity could meet SURMOUNT-CN's threshold while falling outside Taiwan's approval conditions above; someone with a BMI of 28 to under 30 and no comorbidity could meet the Chinese trial's BMI threshold and still not meet Taiwan's conditions.[F1][F8] This is not a judgement about which set of thresholds is better. It is a confirmation that the study population and the approved-use population do not fully overlap.[F10]

Taiwan's conditions are official approval text, and are not an answer about how any individual should be managed.[F8] This article does not offer treatment advice based on BMI figures, and does not rewrite a trial's enrolment threshold into an individual indication assessment.[F8][F10]

Which countries enrolled: check the registry — Taiwan did participate in three trials

Two stacks of paper sit on a desk: on the left, a pile of addressed envelopes with return addresses shown as abstract blocks; on the right, an open bound sign-in book with rows of handwritten entries — clearly different kinds of record. — The institution listed under an author's name is not the same as where participants were actually enrolled.

Whether a trial's enrolment map includes Taiwan should be checked against the `locations` field on ClinicalTrials.gov, and cannot be inferred from the institutional affiliations of paper authors.[F12] This round checked, one by one, the five global trials selected here, two of which double as negative controls. The results follow, with cities only and no named institutions.[F12]

Trial	NCT	Total registered sites	Taiwanese sites
SELECT [F12]	NCT03574597	833	5 (Hsinchu, Kaohsiung, New Taipei, Taipei, Taoyuan)
SURMOUNT-1 [F12]	NCT04184622	118	5 (Taichung ×2, Tainan ×2, Taipei ×1)
SURMOUNT-OSA [F12]	NCT05412004	58	2 (Taichung, Tainan)
SURMOUNT-5 [F12]	NCT05822830	32	0
FLOW (negative control) [F12]	NCT03819153	413	0

The first 3 are positive controls: Taiwan is indeed listed among the enrolment sites. The last 2 are negative controls, demonstrating that this method does not simply mark every global trial as including Taiwan.[F12] But `locations` only establishes that Taiwanese sites participated. It does not publish how many people each Taiwanese site actually randomized, which arm they went to, or what the results were by arm, so no Taiwanese effect can be computed from the table above.[F12][F13]

The original investigation's error was precisely the conflation of two fields: it searched author institutions, not the registry's trial enrolment sites.[F12][F13] An author may have contributed to design, analysis, or writing, and an institutional address is neither a participant's nationality nor an actual enrolment site. Conversely, Taiwan appearing in `locations` does not mean public data has supplied a Taiwanese subgroup analysis.[F13]

The five regional trials this article originally checked can still be reported as they stand: SURMOUNT-CN lists China, SURMOUNT-J lists Japan, STEP 6 lists Japan and South Korea, STEP 7 lists China, Hong Kong, Brazil, and South Korea, and STEP 11 lists South Korea and Thailand; none of those five `locations` fields lists Taiwan.[F9] What was wrong was extrapolating from those five to "Taiwan did not participate in any other trial".[F9][F12]

Disclosures should likewise be reconciled item by item against registry and paper.[F1][F2][F3][F4][F5] The tirzepatide trials cited here, SURMOUNT-CN and SURMOUNT-J, both list Eli Lilly; the semaglutide trials STEP 6, STEP 7, STEP 11, and the global SELECT all list Novo Nordisk.[F1][F2][F3][F4][F5][F7] Sponsor information does not automatically overturn a result, but it is a basic field a reader needs in order to assess the chain of responsibility for design, analysis, and reporting.[F10]

What the existing evidence can and cannot establish

It can establish this: in the Asian or Asian-inclusive populations enrolled by the five regional trials, the randomized tirzepatide or semaglutide arms produced better mean weight outcomes at the specified follow-up point than their respective placebo arms.[F1][F2][F3][F4][F5] It can also establish that Taiwan is listed among the enrolment sites of SELECT, SURMOUNT-1, and SURMOUNT-OSA, and is not listed for SURMOUNT-5 or FLOW.[F12]

It cannot establish this: that the effect in people in Taiwan is equivalent to that in people in China, Japan, or South Korea. The published abstracts and registry results of the three global trials with Taiwanese sites provide no Taiwan-specific effect-modification estimate.[F10][F13] This data cannot answer questions about long-term persistence, discontinuation, switching, rare risks, or access to care under real-world Taiwanese practice, and an author's address or a global average cannot substitute for the missing Taiwanese subgroup analysis.[F10][F13]

If "it works for Asian people" means only that efficacy was observed in Asian study populations, existing randomized trials can support a conditional version of that sentence.[F1][F2][F3][F4][F5] If it is understood to mean the effect is identical across all Asian regions, populations, and clinical settings, the evidence is not sufficient.[F10] Asia is not a single interchangeable biological or care category, and a national label is not a causal mechanism.[F10]

What would have to be found before the Taiwan question could be answered

The next step requires at least two complementary evidence chains.[F10][F13] The first is obtaining the actual Taiwanese enrolment numbers, arm assignments, baseline characteristics, and Taiwan-stratified results from the three global trials, and examining whether the statistical analysis plan pre-specified a regional or national treatment interaction with estimates and confidence intervals; if the public data lists only sites and global totals, a Taiwanese effect cannot be extracted independently.[F12][F13] This material might appear in a full clinical study report, in individual participant data released through a sponsor's data-sharing process, or in a peer-reviewed Taiwanese subgroup analysis — not in a list of author institutions.[F13] The second is a Taiwanese local cohort study whose quality can be assessed, with clear definitions of prescription source, index date, comparator, comorbidity, co-medication, loss to follow-up, discontinuation, and switching, and which handles confounding by indication and time-related bias.[F10]

A local cohort can supply real-world care and longer follow-up, but cannot replace the between-group comparability of a randomized trial.[F10] Establishing whether the effect in Taiwan is "different" would also require pre-defining the comparator and the scale of difference, rather than declaring a regional difference because two studies' mean percentages differ.[F10]

This article also runs positive and negative controls on identifiers: the positive control PMID 38819983 should return SURMOUNT-CN; the negative control uses the non-existent PMID 99999999, and the query should return zero records.[F11] A negative control only demonstrates that the search tool is capable of returning zero results; it cannot license rewriting any non-hit as proof that data does not exist.[F11] As of 2026-08-26, the most robust conclusion is: the registry lists Taiwanese trial centres, but public data discloses neither per-centre enrolment counts nor any Taiwanese subgroup efficacy data.[F12][F13][F14]

This article reviews population-level evidence and does not provide individual diagnosis, prescribing, or advice on stopping or switching drugs.

Would the effect differ for people in Taiwan?: Unknown.[F12][F13] SELECT, SURMOUNT-1, and SURMOUNT-OSA have Taiwanese enrolment sites, but the published abstracts and registry results do not separately list a Taiwanese efficacy estimate; enrolment is not the same as an existing subgroup analysis.[F12][F13]; 台湾の人では効果が違うのですか？ — わかりません。[F12][F13] SELECT、SURMOUNT-1、SURMOUNT-OSA には台湾の実施施設がありますが、公表抄録と登録結果は台湾の有効性推定を個別に示していません。組み入れがあることは、サブグループ解析が存在することと同じではありません。[F12][F13]; Would the effect differ for people in Taiwan? — Unknown.[F12][F13] SELECT, SURMOUNT-1, and SURMOUNT-OSA have Taiwanese enrolment sites, but the published abstracts and registry results do not separately list a Taiwanese efficacy estimate; enrolment is not the same as an existing subgroup analysis.[F12][F13]
How large were the five Asian trials?: The randomized samples were 210, 267, 401, 375, and 150; the study populations and designs differ, so the figures cannot be merged into a single effect.[F1][F2][F3][F4][F5][F10]; 五つのアジア試験の標本はどれくらいですか？ — 無作為割付の人数は順に 210、267、401、375、150 名です。研究集団と設計が異なるため、数値をそのまま統合して単一の効果にすることはできません。[F1][F2][F3][F4][F5][F10]; How large were the five Asian trials? — The randomized samples were 210, 267, 401, 375, and 150; the study populations and designs differ, so the figures cannot be merged into a single effect.[F1][F2][F3][F4][F5][F10]
Why compare against the global studies?: SURMOUNT-1's 2,539 and SELECT's 17,604 give a sense of the scale of evidence, and both list Taiwanese sites; but a global overall result still cannot substitute for a Taiwanese subgroup estimate.[F6][F7][F12][F13]; なぜ国際的な研究を対照に持ち出すのですか？ — SURMOUNT-1 の 2,539 名と SELECT の 17,604 名はエビデンスの規模の尺度を与え、しかも両者とも台湾の施設を記載しています。ただし国際的な全体の結果はやはり台湾サブグループの推定を代替できません。[F6][F7][F12][F13]; Why compare against the global studies? — SURMOUNT-1's 2,539 and SELECT's 17,604 give a sense of the scale of evidence, and both list Taiwanese sites; but a global overall result still cannot substitute for a Taiwanese subgroup estimate.[F6][F7][F12][F13]
Can the Chinese trial stand in for Taiwan's approved population?: No.[F1][F8] SURMOUNT-CN used a BMI of at least 28, or at least 24 with a comorbidity; Taiwan's Mounjaro conditions are at least 30, or 27 to under 30 with a comorbidity.[F1][F8]; 中国の試験は台湾の承認対象集団をそのまま代表できますか？ — できません。[F1][F8] SURMOUNT-CN は BMI 28 以上、または 24 以上かつ併存疾患ありを採用しています。台湾のマンジャロの条件は 30 以上、または 27 以上 30 未満かつ併存疾患ありです。[F1][F8]; Can the Chinese trial stand in for Taiwan's approved population? — No.[F1][F8] SURMOUNT-CN used a BMI of at least 28, or at least 24 with a comorbidity; Taiwan's Mounjaro conditions are at least 30, or 27 to under 30 with a comorbidity.[F1][F8]
Can enrolment location be determined from the authors' addresses?: It cannot.[F12][F13] The earlier version missed Taiwan precisely because it searched author institutions; the trial registration's `locations` field is what should be checked, because an author's institution is not an enrolment site.[F12][F13]; 論文著者の住所からどこで組み入れたか判断できますか？ — できません。[F12][F13] 旧版はまさに著者の所属機関を調べたために台湾を見落としました。試験登録の `locations` を調べるべきであり、著者の所属機関は実際の実施施設ではないからです。[F12][F13]; Can enrolment location be determined from the authors' addresses? — It cannot.[F12][F13] The earlier version missed Taiwan precisely because it searched author institutions; the trial registration's `locations` field is what should be checked, because an author's institution is not an enrolment site.[F12][F13]
Who sponsored these core trials?: The two Asian tirzepatide trials cited here list Eli Lilly, and the three Asian semaglutide trials plus SELECT list Novo Nordisk.[F1][F2][F3][F4][F5][F7]; これらの中核的な試験の資金提供者は誰ですか？ — 本稿が引用する二つのチルゼパチドのアジア試験は Eli Lilly を、三つのセマグルチドのアジア試験と SELECT は Novo Nordisk を記載しています。[F1][F2][F3][F4][F5][F7]; Who sponsored these core trials? — The two Asian tirzepatide trials cited here list Eli Lilly, and the three Asian semaglutide trials plus SELECT list Novo Nordisk.[F1][F2][F3][F4][F5][F7]
What kind of data would narrow the Taiwanese evidence gap?: Actual Taiwanese enrolment counts, arm assignments, Taiwan-stratified results, and a pre-specified national or regional interaction with confidence intervals; a well-designed Taiwanese local cohort study could additionally address real-world care questions.[F10][F13]; どのようなデータがあれば台湾のエビデンスの欠落を縮められますか？ — 台湾の実際の組み入れ人数、群分け、台湾で層別した結果、そしてあらかじめ規定された国別あるいは地域別の交互作用と信頼区間が必要です。加えて、設計の明確な台湾の地域コホート研究が実際の医療に関する問いを補いえます。[F10][F13]; What kind of data would narrow the Taiwanese evidence gap? — Actual Taiwanese enrolment counts, arm assignments, Taiwan-stratified results, and a pre-specified national or regional interaction with confidence intervals; a well-designed Taiwanese local cohort study could additionally address real-world care questions.[F10][F13]
