Study ASC30-302 (AURORA-2) is a Phase III, global, multicenter, randomized, double-blind, placebo-controlled study to investigate the long-term efficacy, safety, and tolerability of three maintenance doses of once-daily oral ASC30 compared with placebo in participants with obesity or overweight and T2DM.
11,522 studies on the registry are indexed under Obesity; 2,033 are open to participants now.
This study's planned enrollment of 1,560 is above the median of 67 across 9,006 interventional studies indexed under Obesity.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
BMI (body mass index)
Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

HbA1c
A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Started Aug 2026 (actual). Primary completion is estimated for Jul 2028, 23 months after the start.
Of 198 industry-sponsored phase 3 interventional studies under Obesity, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 27. This study's planned 23 months is close to that.
Counting every sponsor, half of 261 studies reached it within 24 months; a quarter within 18 and three quarters within 34.
