hormone receptor agonist treatments. Survodutide is
targeting the treatment of obesity and MASH.
In 2023, Boehringer Ingelheim advanced survodutide into a
global Phase 3 program in people living with overweight or
obesity (SYNCHRONIZE
TM
).
SYNCHRONIZE
TM
-1 (ClinicalTrials.gov ID: NCT06066515)
and SYNCHRONIZE
TM
-2 (ClinicalTrials.gov ID:
NCT06066528) are Phase 3 trials investigating survodutide
in people with obesity (eligible BMI ≥30) or overweight
(eligible BMI ≥27) with comorbidities, including dyslipidemia,
hypertension and obstructive sleep apnea.
SYNCHRONIZE
TM
-1 will enroll people without type 2
diabetes (eligible HbA1c <6.5%) and SYNCHRONIZE
TM
-2 will
enroll people with type 2 diabetes (eligible HbA1c ≥6.5%
<10%). For both trials, the primary endpoints are percentage
change in body weight at week 76 and the proportion of
people who achieve body weight loss of 5% or more at week
76. A total of 600 participants will be enrolled in each of the
two trials, randomized to receive weekly subcutaneous
injections of either survodutide, reaching a maximum dose
of 3.6 mg or 6.0 mg for maintenance treatment, or placebo.
SYNCHRONIZE
TM
-CVOT (ClinicalTrials.gov ID:
NCT06077864) is a Phase 3 trial that will enroll people with
overweight or obesity with cardiovascular disease, chronic
kidney disease, or risk factors for cardiovascular disease. In
SYNCHRONIZE
TM
-CVOT, the primary endpoint is the time to
first occurrence of any one of five major adverse cardiac
events (5P-MACE): cardiovascular death, non-fatal stroke,
non-fatal myocardial infarction, ischemia-related coronary
revascularization and heart failure events.
Phase 3 trials with survodutide in Chinese people living with
overweight or obesity, SYNCHRONIZE
TM
-CN
(ClinicalTrials.gov ID: NCT06214741), and in Japanese
people living with overweight or obesity, SYNCHRONIZE
TM
-
JP (ClinicalTrials.gov ID: NCT06176365), have also been
initiated. A Phase 3 trial in people with overweight or obesity
and confirmed or presumed metabolic dysfunction-
associated steatohepatitis (MASH) (ClinicalTrials.gov ID:
NCT06309992) has also been initiated.
Advancement of survodutide to Phase 3 trials in people with
overweight or obesity was based on positive results in
separate Phase 2 trials in obesity, type 2 diabetes and most
recently MASH. A Phase 2 randomized, placebo-controlled,
double-blind trial evaluated survodutide compared to
placebo in people with overweight or obesity
(ClinicalTrials.gov ID: NCT04667377). Participants received
multiple rising doses of survodutide in one of four dose
groups or placebo and included 20 weeks of dose
escalation and 26 weeks of maintenance. Based on the
planned maintenance dose assigned at randomization
regardless of whether the planned dose was reached during
the dose escalation phase, survodutide achieved up to 14.9%
mean weight loss from baseline after 46 weeks. An analysis
based on the actual maintenance dose regardless of
assignment at randomization, showed up to 18.7% mean
weight loss after 46 weeks. Bodyweight reductions with
survodutide had not reached a plateau at week 46,
suggesting additional weight loss could be achieved with
longer treatment duration. Up to 40% of people who
reached the highest two doses of survodutide, 3.6 mg and
4.8 mg, achieved a weight loss of at least 20%.
Serious adverse events were reported by 4.2% of participants
on survodutide versus 6.5% of those on placebo. Treatment
discontinuation due to adverse events occurred in 24.6%
and 3.9% of participants on survodutide and placebo,
respectively, mainly due to gastrointestinal adverse events.
Most treatment discontinuations due to adverse events
occurred during the rapid 20-week dose-escalation phase
with up-titration every second week. Thus, the safety and
tolerability profile of survodutide was in line with other
incretin-based pharmacotherapies. The treatment
discontinuation rate of survodutide was also roughly similar
to the treatment discontinuation rates seen with other
incretin-based pharmacotherapies in previous Phase 2 trials
in type 2 diabetes and obesity. Boehringer Ingelheim and
Zealand Pharma expect that treatment discontinuations due
to adverse events can be mitigated with more gradual dose
escalation over a longer duration in Phase 3. The detailed
results from the Phase 2 trial were presented at the ADA 83
rd
Scientific Sessions in June 2023. Additional data, presented
at the 59
th
Annual Meeting of the European Association for
the Study of Diabetes (EASD) in October 2023,
demonstrated reductions in absolute waist circumference
(up to 16.0 cm), absolute body weight (up to 19.5 kg) and
absolute systolic and diastolic blood pressure (up to 8.6
mmHg and 4.8 mmHg, respectively).
A Phase 2 randomized, placebo-controlled, double-blind
trial evaluated survodutide in people with type 2 diabetes on
stable metformin background therapy (ClinicalTrials.gov ID:
NCT04153929). Participants received multiple rising doses
of survodutide in one of six dose groups, placebo or open-
label weekly semaglutide 1.0 mg for 16 weeks. Treatment
with survodutide led to dose-dependent decreases in
HbA1c, with mean reductions of -0.93% to -1.88% at 16
weeks across the six dose groups, compared with -0.25%
seen with placebo. Treatment with open-label weekly
semaglutide at 1.0 mg led to a decrease in HbA1c of -1.47%.
Boehringer Ingelheim presented these results at the 58th
Annual Meeting of the European Association for the Study
of Diabetes (EASD) in September 2022.
A third Phase 2 trial assessed survodutide in metabolic
dysfunction-associated steatohepatitis (MASH), formerly
known as non-alcoholic steatohepatitis (NASH), and liver
fibrosis stages F1/F2/F3 (ClinicalTrials.gov ID:
NCT04771273). The double-blind, placebo-controlled trial
studied three doses of survodutide at 2.4 mg, 4.8mg and 6.0
mg. At the highest dose, 83.0% of adults treated with
survodutide achieved a biopsy-proven improvement in
MASH after 48 weeks without worsening of fibrosis stages
