1
00:00:02,000 --> 00:00:05,160
Zenagamtide was first known as amycretin.

2
00:00:05,760 --> 00:00:09,480
It brings complementary hormone signals into one engineered

3
00:00:09,480 --> 00:00:13,540
peptide rather than combining two separate medicines.

4
00:00:14,440 --> 00:00:16,700
Novo Nordisk developed it in Denmark.

5
00:00:17,460 --> 00:00:20,900
Agnes Gasiorek and colleagues reported an early oral

6
00:00:20,900 --> 00:00:24,380
study in 2025 conducted at a research unit

7
00:00:24,380 --> 00:00:26,360
in San Antonio, Texas.

8
00:00:27,220 --> 00:00:32,080
The peptide activates GLP-1, amylin and calcitonin

9
00:00:32,080 --> 00:00:37,220
receptors connecting glucose regulation with appetite and fullness.

10
00:00:38,220 --> 00:00:42,180
These structural views show receptor architecture, not a

11
00:00:42,180 --> 00:00:44,140
Zenagamtide binding experiment.

12
00:00:45,000 --> 00:00:48,720
Scientists are studying oral and injectable formulations.

13
00:00:49,520 --> 00:00:54,840
Separate phase 2 analyses included 186 oral participants

14
00:00:54,840 --> 00:01:00,680
and 262 injectable participants with type 2 diabetes.

15
00:01:01,980 --> 00:01:07,160
At 36 weeks, estimated hemoglobin A1c reductions ranged

16
00:01:07,160 --> 00:01:12,460
from 0.9 to 1.7 percentage points in injectable

17
00:01:12,460 --> 00:01:18,120
groups and 0.9 to 1.4 in oral groups.

18
00:01:19,060 --> 00:01:21,160
These are separate route analyses,

19
00:01:21,900 --> 00:01:23,300
not a head-to-head comparison.

20
00:01:24,620 --> 00:01:28,660
Gastrointestinal and serious adverse events were reported.

21
00:01:29,300 --> 00:01:32,400
Long-term safety still requires more evidence.

22
00:01:33,540 --> 00:01:38,220
At the October 13, 2026 cutoff, Zenagamtide remains

23
00:01:38,220 --> 00:01:39,960
investigational.

24
00:01:40,180 --> 00:01:42,160
AMAZE studies obesity,

25
00:01:42,780 --> 00:01:45,600
AMBITION studies type 2 diabetes.

26
00:01:46,960 --> 00:01:49,380
Next, eloralintide.

27
00:01:49,600 --> 00:01:51,080
Peptides in 2.

28
00:01:51,400 --> 00:01:52,580
World Peptide Foundation.

29
00:01:53,000 --> 00:01:54,480
Every experience matters.
