In regards to the research

Within the current research, researchers investigated the results of continued remedy with tirzepatide on sustaining weight reduction in obese or overweight people. This trial, SURMOUNT-4, was a randomized withdrawal research performed in america, Argentina, Taiwan, and Brazil between March 29, 2021, and Could 18, 2023.

The trial included a 36-week open-label lead-in tirzepatide remedy interval, adopted by a 52-week placebo-controlled double-blind interval. Eligible contributors had been adults aged 18 or older with a physique mass index (BMI) ≥ 30 kg/m2 or 27 kg/m2 and not less than one weight-related complication (heart problems, sleep apnea, hypertension, or dyslipidemia).

People with diabetes or deliberate/prior surgical procedure for weight problems and people on weight reduction drugs throughout the previous three months had been excluded. Tirzepatide was administered as a subcutaneous injection as soon as per week. Throughout the lead-in interval, the tirzepatide dose was incremented by 2.5 mg each 4 weeks till the utmost tolerated dose (10 or 15 mg) was achieved.

On the finish of 36 weeks, contributors had been randomized to proceed remedy with the utmost tolerated dose of tirzepatide or change to a placebo for 52 weeks. The first endpoint was the p.c change in physique weight between weeks 36 and 88. Secondary endpoints had been weight upkeep, regain, and adjustments in cardiometabolic danger elements.


General, 783 contributors had been enrolled within the lead-in interval. Of those, 113 people had been excluded from randomization as a result of hostile occasions, withdrawal, and protocol deviation, amongst different causes. In complete, 670 contributors had been randomized to proceed remedy with the utmost tolerated dose of tirzepatide or obtain a placebo.

Most randomized people had been feminine and White. The typical length of weight problems was 15.5 years. Almost 70% of contributors had not less than one weight-related complication. Dyslipidemia and hypertension had been essentially the most prevalent weight-related problems. Medical traits and demographics had been comparable between teams.

Throughout the 36-week lead-in interval, the typical weight reduction was 20.9% amongst randomized contributors. Moreover, BMI and waist circumference decreased, whereas patient-reported outcomes, lipid ranges, glycemic parameters, and blood stress improved. The typical p.c change in weight from weeks 36 to 88 was -5.5% with tirzepatide and 14% with placebo.

At week 88, a considerably greater proportion of tirzepatide recipients maintained not less than 80% of the burden loss achieved in the course of the lead-in interval. Moreover, persevering with tirzepatide remedy past the lead-in interval decreased the chance of returning to > 95% baseline weight by 98% for many who misplaced ≥ 5% physique weight since week 0.

Continued remedy was related to important enhancements in BMI, glycated hemoglobin, fasting glucose, blood stress, insulin, and lipid ranges by week 88. Tirzepatide remedy was related to enhancements in BMI, patient-reported outcomes, and cardiometabolic parameters all through the research (from week 0).

General, 81% of contributors had not less than one treatment-emergent hostile occasion in the course of the lead-in interval. Nausea, diarrhea, constipation, and vomiting had been the commonest hostile occasions. Within the double-blind interval, 60.3% of tirzepatide recipients and 55.8% of placebo recipients reported not less than one hostile occasion.

Gastrointestinal problems and coronavirus illness 2019 (COVID-19) had been the commonest within the double-blind interval. Sixteen contributors within the lead-in interval and ten in the course of the double-blind interval skilled critical hostile occasions. One demise occurred in the course of the lead-in interval and two within the double-blind interval. The investigators deemed these deaths unrelated to the research drug.


The findings emphasize persevering with remedy to maintain weight discount and forestall weight regain in obese and overweight adults. Though placebo recipients ended the research with a considerable lower in physique weight, enhancements in cardiometabolic parameters had been reversed. In sum, after attaining weight discount in the course of the 36-week lead-in interval, adults who continued the remedy with the utmost tolerated dose of tirzepatide for one 12 months confirmed superior weight upkeep in comparison with placebo recipients.
