What Did the 2026 Retatrutide Phase 3 Trials Show?

Retatrutide research moved substantially beyond early Phase 2 studies in 2026, with Eli Lilly reporting results from several Phase 3 programs investigating the compound across obesity, type 2 diabetes, cardiovascular disease, knee osteoarthritis, and other metabolic conditions.

These studies are important because Phase 3 trials generally involve larger patient populations and are designed to provide more definitive evidence about efficacy and safety than earlier-stage trials. However, it is important to distinguish between company-reported topline results and results that have already appeared as fully peer-reviewed journal publications.

As of September 2026, retatrutide remains an investigational compound. Eli Lilly states that it has not been approved by the FDA or any other regulatory agency and is currently available only through clinical trials.

For the latest regulatory and development information, see Eli Lilly's current retatrutide FAQ.

TRIUMPH-1: Retatrutide in Obesity Without Diabetes

One of the most closely watched 2026 studies was TRIUMPH-1, a Phase 3 study evaluating retatrutide in adults with obesity who did not have diabetes.

According to Eli Lilly's May 2026 topline announcement, participants receiving retatrutide experienced substantial reductions in body weight over the 80-week study period.

At the 12 mg dose, Eli Lilly reported an average body-weight reduction of approximately 28.3% at 80 weeks. The company also reported that approximately 45.3% of participants in this group achieved at least 30% weight loss.

These findings are substantially larger in magnitude than the average weight reductions observed in the earlier 48-week Phase 2 obesity study, although direct comparisons between trials should be made cautiously because study populations, durations, designs, and analytical methods can differ.

The Phase 2 study had previously demonstrated a dose-dependent pattern of weight reduction, with the highest studied dose producing a mean reduction of approximately 24.2% at 48 weeks. The full peer-reviewed Phase 2 results are available through PubMed: Triple-Hormone-Receptor Agonist Retatrutide for Obesity.

For the subsequent Phase 3 results, see Eli Lilly's TRIUMPH-1 results announcement.

TRANSCEND-T2D-1: Retatrutide and Type 2 Diabetes

Retatrutide is also being investigated in populations with type 2 diabetes, where researchers are interested in both its effects on body weight and its effects on glycemic measures such as hemoglobin A1C.

In June 2026, Eli Lilly reported topline results from TRANSCEND-T2D-1. According to the company's announcement, retatrutide produced dose-dependent reductions in both body weight and A1C over 40 weeks.

The company reported:

• Body-weight reductions of up to approximately 16.8% at 40 weeks.
• A1C reductions of up to approximately 2.0 percentage points.
• Up to approximately 46% of participants reaching a normal A1C range in the reported analysis.

These results build on the earlier Phase 2 type 2 diabetes trial, which was published in The Lancet. That study investigated retatrutide against placebo and an active comparator in people with type 2 diabetes.

The peer-reviewed Phase 2 findings can be reviewed through PubMed: Retatrutide in People With Type 2 Diabetes.

The 2026 Phase 3 results are summarized in Eli Lilly's June 2026 clinical-development update.

From a pharmacology perspective, the combination of GLP-1, GIP, and glucagon receptor activity is particularly relevant to metabolic research because these pathways influence overlapping but distinct aspects of glucose regulation, appetite signaling, energy metabolism, and nutrient handling.

TRIUMPH-2: Retatrutide in Obesity With Type 2 Diabetes

TRIUMPH-2 examined retatrutide in adults with obesity or overweight and type 2 diabetes.

According to Eli Lilly's July 2026 results announcement, average body-weight reductions at 80 weeks were:

The company also reported A1C reductions of up to approximately 1.6 percentage points.

The difference between the results reported in TRIUMPH-1 and TRIUMPH-2 illustrates why study population matters. Participants with type 2 diabetes can have different metabolic characteristics, background treatments, baseline body weight, and glycemic physiology compared with participants without diabetes.

Therefore, researchers should avoid treating a single retatrutide percentage as a universal expected outcome.

The full company announcement is available through Eli Lilly's July 2026 TRIUMPH-2 and TRIUMPH-3 update.

TRIUMPH-3: Obesity With Established Cardiovascular Disease

TRIUMPH-3 investigated retatrutide in a population with severe obesity and established cardiovascular disease, with or without type 2 diabetes.

Eli Lilly reported the following average body-weight reductions at 80 weeks:

This trial is particularly relevant to the broader research question of whether substantial weight reduction can be studied in populations with significant cardiometabolic disease.

However, body-weight change should not be interpreted as proof of a cardiovascular outcome benefit. Cardiovascular outcomes are a separate scientific question requiring appropriately designed outcomes trials.

Eli Lilly has described additional cardiovascular and renal outcome research as part of its broader retatrutide development program. Current trial-development information is summarized in Eli Lilly's retatrutide development overview.

TRIUMPH-4 and Knee Osteoarthritis Research

Retatrutide is also being studied in people with obesity and knee osteoarthritis, creating an opportunity to investigate the relationship between metabolic weight reduction and musculoskeletal outcomes.

In 2026, Eli Lilly reported results from TRIUMPH-4. According to company-reported results, average body-weight reductions at 68 weeks were approximately:

• 26.4% with 9 mg retatrutide
• 28.7% with 12 mg retatrutide

The company also reported improvements in knee osteoarthritis pain measures in this research program.

These findings are scientifically interesting because obesity, mechanical loading, inflammation, and osteoarthritis symptoms can interact in complex ways. Nevertheless, improvements in symptoms should be distinguished from claims about direct tissue regeneration or cartilage repair unless those mechanisms are specifically demonstrated.

For current company-reported TRIUMPH-4 information and related results, see Eli Lilly's 2026 investor presentation.

Retatrutide and Obstructive Sleep Apnea Research

Obstructive sleep apnea (OSA) is another area being investigated in the retatrutide development program.

In its 2026 clinical updates, Eli Lilly reported reductions in OSA severity among participants receiving retatrutide. The company reported reductions of up to approximately 36.1 events per hour, corresponding to a reported reduction of approximately 60.6% in the relevant analysis.

OSA research is particularly relevant to metabolic science because excess adiposity can contribute to upper-airway obstruction and altered respiratory physiology. However, OSA is multifactorial, and the relationship between body-weight reduction and sleep-disordered breathing requires dedicated clinical evaluation.

Eli Lilly's current retatrutide development program includes OSA research alongside obesity, diabetes, cardiovascular, renal, liver, and musculoskeletal endpoints. See the company's retatrutide development overview for the current program description.

Retatrutide vs Semaglutide

One of the most common research questions is how retatrutide differs from semaglutide.

The most important distinction is receptor pharmacology.

Semaglutide primarily activates the GLP-1 receptor. Retatrutide was engineered to activate three receptors: GLP-1R, GIPR, and GCGR.

This difference does not mean that one compound can automatically be considered superior to another. Instead, it means that they represent different pharmacological strategies.

Retatrutide's triple-agonist design is one reason researchers are interested in studying whether simultaneous modulation of these pathways produces metabolic effects beyond those achievable through GLP-1 receptor activation alone.

For background on how peptide medicines and research peptides differ, see What Are Research Peptides?.

Retatrutide vs Tirzepatide

Retatrutide is also frequently compared with tirzepatide because both compounds activate more than one metabolic hormone receptor.

The addition of glucagon receptor activity is a defining feature of retatrutide.

Glucagon signaling can influence hepatic glucose metabolism and energy expenditure, while GLP-1 and GIP signaling can influence glucose-dependent insulin secretion and other metabolic processes. Retatrutide therefore represents an attempt to combine three complementary signaling pathways within a single molecular framework.

Structural and receptor-level research has examined how retatrutide interacts with GLP-1R, GIPR, and GCGR. A useful starting point is the peer-reviewed article Structural Insights Into the Triple Agonism at GLP-1R, GIPR and GCGR Manifested by Retatrutide.

Retatrutide, Semaglutide, and Tirzepatide: Understanding the Receptor Differences

A simplified way to visualize the three compounds is to consider the number of hormone-receptor pathways they directly engage:

• Semaglutide: GLP-1 receptor agonism
• Tirzepatide: GLP-1 and GIP receptor agonism
• Retatrutide: GLP-1, GIP, and glucagon receptor agonism

However, receptor count alone does not determine the biological effect of a peptide. Researchers also need to consider receptor potency, signaling bias, pharmacokinetics, molecular structure, tissue distribution, dose exposure, and the physiological context in which the compound is studied.

What Are the Known Safety and Tolerability Findings?

Safety and tolerability are essential components of retatrutide research.

In the peer-reviewed Phase 2 obesity trial, gastrointestinal adverse events were among the most frequently reported events. These included symptoms such as nausea, diarrhea, and vomiting. The investigators reported that gastrointestinal events were generally mild to moderate.

Because the 2026 Phase 3 program is still being reported and published across multiple studies, the complete safety profile should be evaluated from the full datasets rather than from isolated headlines or individual adverse-event percentages.

The original peer-reviewed obesity trial provides an important baseline for understanding retatrutide tolerability and can be reviewed through the Phase 2 NEJM study indexed by PubMed.

Researchers evaluating peptide quality should also distinguish clinical safety from analytical purity. A highly pure research material does not automatically establish clinical safety, efficacy, or suitability for human use.

For more information about analytical testing, see Understanding HPLC Testing: A Complete Guide to Peptide Purity Analysis.

Why HPLC and Mass Spectrometry Matter in Retatrutide Research

When researchers work with a synthetic peptide such as retatrutide, analytical characterization is an important component of experimental quality control.

High-performance liquid chromatography (HPLC) can be used to assess chromatographic purity and identify the presence of detectable components that separate under the analytical method.

Mass spectrometry (MS) provides information about molecular mass and can support compound identity assessment.

These techniques answer different questions. HPLC retention behavior and peak areas can provide information about chromatographic composition, while mass spectrometry can provide molecular-weight information consistent with the expected compound.

For a deeper explanation of these analytical concepts, read Understanding HPLC Testing and How Peptides Are Manufactured.

Researchers can also review the broader principles of peptide quality assessment in Diamond Peptides' Research Peptide Buying Guide for Canada.

Is Retatrutide FDA Approved?

No. Retatrutide remains investigational as of September 2026.

Eli Lilly states that retatrutide has not been approved by the FDA or any other regulatory agency. The company describes it as an investigational once-weekly triple hormone receptor agonist currently being studied in clinical trials.

This distinction is important when evaluating websites or advertisements that describe retatrutide as an approved medication.

Current regulatory status can change as clinical development progresses, so researchers should verify the status through authoritative regulatory and manufacturer sources. The current information is available through Eli Lilly's retatrutide FAQ.

Is Retatrutide Approved in Canada?

Retatrutide should not be described as an approved therapeutic product in Canada while it remains investigational and unapproved by regulatory agencies.

Canadian regulatory information should be checked through Health Canada and other official Canadian regulatory resources rather than relying on vendor claims.

For research purposes, the distinction between an investigational compound and an approved therapeutic product is fundamental. Research materials sold for laboratory investigation should not be represented as approved medicines or as products intended for human treatment.

What Does the Current Retatrutide Research Actually Tell Us?

By 2026, retatrutide research had progressed from receptor-level and early clinical investigation into a broad Phase 3 development program.

The evidence base now includes:

• Peer-reviewed Phase 2 obesity research.
• Peer-reviewed Phase 2 type 2 diabetes research.
• Structural research examining triple receptor agonism.
• Large Phase 3 programs reported by Eli Lilly in 2026.
• Research examining obesity, diabetes, cardiovascular disease, knee osteoarthritis, and obstructive sleep apnea.
• Additional metabolic and multi-omic investigations exploring potential biological mechanisms.

At the same time, not every 2026 result has yet been published as a complete peer-reviewed manuscript. This distinction is especially important for anyone researching retatrutide online because company press releases, conference presentations, clinical-trial records, peer-reviewed publications, and secondary media reports provide different levels of methodological detail.

The strongest approach is therefore to examine the study design, population, endpoints, duration, statistical analysis, adverse events, and publication status rather than relying solely on a headline percentage.

Retatrutide as a Research Peptide

Retatrutide is of particular interest to peptide researchers because it illustrates how modern peptide engineering can be used to influence multiple biological signaling systems through a single molecule.

From a research perspective, important areas include:

• Triple receptor pharmacology
• GLP-1 receptor signaling
• GIP receptor signaling
• Glucagon receptor signaling
• Metabolic pathway modulation
• Energy-balance research
• Glucose metabolism
• Peptide structure-function relationships
• Pharmacokinetic research
• Analytical characterization
• Receptor activation and signaling

How Does Retatrutide Work at the Molecular Level?

Understanding retatrutide requires looking beyond the phrase “triple agonist.” The compound is scientifically interesting because it combines activity at three G-protein-coupled receptors (GPCRs) involved in metabolic regulation: the glucagon-like peptide-1 receptor (GLP-1R), glucose-dependent insulinotropic polypeptide receptor (GIPR), and glucagon receptor (GCGR).

Each receptor belongs to the class B GPCR family and participates in complex intracellular signaling networks. Activating these receptors can influence processes including insulin secretion, glucagon signaling, appetite regulation, glucose metabolism, and energy balance.

Retatrutide's research significance therefore comes from its ability to engage three related but distinct receptor systems through one engineered peptide molecule.

GLP-1 Receptor Signaling

The GLP-1 receptor is a well-characterized metabolic receptor expressed in multiple tissues. GLP-1 receptor signaling has been extensively studied because endogenous GLP-1 participates in glucose-dependent insulin secretion and other physiological processes related to nutrient intake and energy regulation.

Activation of GLP-1R is associated with intracellular signaling involving cyclic adenosine monophosphate (cAMP), protein kinase pathways, and other downstream signaling networks.

In the context of retatrutide, GLP-1 receptor activity represents one component of the molecule's overall pharmacological profile.

This is also the receptor pathway shared with several established GLP-1 receptor agonist medicines, although retatrutide differs because it simultaneously activates GIPR and GCGR.

Researchers interested in the broader biology of peptide receptor signaling can explore the primary literature through PubMed's GLP-1 receptor signaling literature.

GIP Receptor Signaling

The glucose-dependent insulinotropic polypeptide receptor, or GIPR, is another class B GPCR involved in metabolic signaling.

GIP is an incretin hormone released in response to nutrient ingestion. Its biological effects include glucose-dependent insulinotropic activity and signaling across several tissues.

Retatrutide's ability to activate GIPR distinguishes it from selective GLP-1 receptor agonists.

GIP receptor biology has also become increasingly important in the development of multi-receptor metabolic peptides. Tirzepatide, for example, combines GIP and GLP-1 receptor activity, while retatrutide adds glucagon receptor activity to the same general incretin-based framework.

For retatrutide researchers, this creates an important question: how does adding glucagon receptor signaling to GLP-1 and GIP receptor activity change the overall metabolic response?

That question is one of the central scientific themes behind the triple-agonist approach.

Glucagon Receptor Signaling

The third component of retatrutide's receptor profile is the glucagon receptor (GCGR).

Glucagon is traditionally associated with increasing blood glucose through actions that promote hepatic glucose production. However, glucagon biology is considerably more complex than simply describing it as an “opposite” of insulin.

Glucagon signaling can influence:

• Hepatic glucose metabolism
• Lipid metabolism
• Energy expenditure
• Substrate utilization
• Interactions between glucose and fatty-acid metabolism

Retatrutide was engineered to incorporate glucagon receptor activity alongside GLP-1 and GIP receptor activity.

This creates a pharmacological balance in which pathways associated with glucose-dependent incretin signaling are combined with glucagon-mediated metabolic signaling.

The precise contribution of each receptor to the overall clinical phenotype remains an active area of research.

Why Is Glucagon Receptor Activity Important?

One of the most interesting aspects of retatrutide research is the attempt to harness glucagon signaling without studying glucagon activity in isolation.

Researchers have investigated glucagon-based approaches for decades because glucagon can affect energy expenditure and substrate metabolism. However, isolated glucagon receptor activation can also increase blood glucose.

Retatrutide therefore represents a different strategy: combining glucagon receptor activity with GLP-1 and GIP receptor activity within a single molecule.

The resulting pharmacological profile is substantially more complex than a conventional single-receptor agonist.

Structural research has examined how retatrutide interacts with all three receptors. The peer-reviewed study Structural Insights Into the Triple Agonism at GLP-1R, GIPR and GCGR Manifested by Retatrutide provides useful molecular context.

Retatrutide and Energy Metabolism

Another important area of retatrutide research involves energy metabolism.

Weight regulation is not controlled by a single biological pathway. It involves interactions among appetite signaling, gastrointestinal physiology, insulin and glucagon signaling, adipose tissue metabolism, hepatic metabolism, energy expenditure, and the central nervous system.

Because retatrutide engages three metabolic hormone receptors, researchers have investigated whether its effects extend beyond changes in food intake.

Some preclinical and clinical analyses have examined changes in metabolic substrates, lipid profiles, and pathways associated with energy utilization.

A 2026 exploratory metabolomics and lipidomics analysis examined changes associated with retatrutide treatment in people with obesity, with and without type 2 diabetes. The analysis reported changes in metabolites associated with fatty-acid oxidation and insulin resistance.

The study is available through PubMed's 2026 retatrutide metabolomics and lipidomics research.

Retatrutide and Fat Metabolism

Researchers are particularly interested in whether triple-receptor activation can influence how the body handles stored and circulating lipids.

Glucagon signaling is strongly connected with hepatic and lipid metabolism, while incretin pathways influence nutrient handling and insulin physiology.

The combination creates an opportunity to investigate whether coordinated signaling across these pathways changes substrate utilization in ways that differ from single-receptor approaches.

However, terms such as “fat burning” can oversimplify the underlying biology. Human metabolism involves continuous shifts among carbohydrate, lipid, and protein substrates, and changes in circulating biomarkers do not necessarily translate directly into changes in long-term body composition.

For research purposes, it is more precise to discuss substrate oxidation, lipid metabolism, energy expenditure, and changes in metabolic biomarkers rather than reducing the mechanism to a simple fat-burning claim.

Retatrutide and Appetite Signaling

Appetite regulation is another major component of retatrutide research.

GLP-1 and GIP signaling can influence gastrointestinal and central pathways involved in nutrient sensing and appetite. Retatrutide's glucagon receptor activity adds another metabolic signaling component.

Clinical studies have demonstrated substantial reductions in body weight, but body-weight change is the result of multiple interacting mechanisms.

Researchers therefore study appetite, food intake, energy expenditure, body composition, metabolic biomarkers, and hormonal signaling rather than assuming that a single mechanism explains the entire effect.

This distinction is particularly important when evaluating online claims about how retatrutide “works.” Mechanistic explanations should be tied to experimentally measured outcomes whenever possible.

Retatrutide and Glycemic Regulation

Glucose metabolism is another major area of investigation.

GLP-1 and GIP receptor activation can support glucose-dependent insulinotropic signaling, while glucagon receptor activity can influence hepatic glucose metabolism.

The overall effect is therefore determined by the interaction among the three pathways rather than by any single receptor.

Clinical research in people with type 2 diabetes has provided evidence that retatrutide can influence glycemic measures, including A1C. The earlier Phase 2 trial published in The Lancet provides peer-reviewed evidence, while later Phase 3 results have been reported by Eli Lilly.

Researchers can review the Phase 2 evidence through PubMed's record for the retatrutide type 2 diabetes Phase 2 trial.

What Is LY3437943?

LY3437943 is the development code associated with retatrutide.

When searching scientific databases, researchers may encounter either “retatrutide” or “LY3437943.” Searching both terms can therefore help identify a broader set of research papers, clinical-trial records, and scientific presentations.

For example, PubMed can be searched using LY3437943 as well as retatrutide.

Development codes are common in pharmaceutical research. A compound can have an internal development identifier before receiving a standardized nonproprietary name or other designation.

How Was Retatrutide Designed?

Retatrutide belongs to a broader field of peptide engineering in which researchers modify peptide sequences and structures to influence receptor selectivity, potency, pharmacokinetics, and biological stability.

Designing a multi-receptor agonist is substantially more complicated than designing a molecule that targets only one receptor.

The molecule must maintain appropriate structural characteristics while interacting productively with multiple receptor systems.

Research into retatrutide's structure therefore provides insight into a broader question in modern peptide science: can a single engineered peptide be optimized to produce coordinated signaling across several related receptors?

This is one reason retatrutide has attracted substantial interest beyond its potential metabolic effects.

For a broader overview of peptide production and characterization, see How Peptides Are Manufactured.

Retatrutide and Peptide Structure-Function Relationships

In peptide research, relatively small structural changes can alter receptor binding, stability, potency, and biological activity.

Important structural variables can include:

• Amino-acid sequence
• Side-chain modifications
• Terminal modifications
• Lipidation or other chemical modifications
• Three-dimensional conformation
• Receptor-binding interactions
• Resistance to enzymatic degradation

For multi-receptor peptides, these variables become especially important because the molecule must interact with multiple receptor environments.

Structural biology can therefore complement traditional pharmacological experiments by helping researchers understand why a peptide produces a particular receptor-activation profile.

The 2024 structural study of retatrutide provides an example of this approach and can be accessed through PubMed.

What Does “Triple Agonist” Actually Mean?

An agonist is a molecule that binds to a receptor and activates receptor-associated signaling.

In retatrutide's case, “triple agonist” refers specifically to activity at:

1. GLP-1R — glucagon-like peptide-1 receptor
2. GIPR — glucose-dependent insulinotropic polypeptide receptor
3. GCGR — glucagon receptor

It does not mean that retatrutide contains three separate peptides.

It also does not mean that all three receptors are activated equally in every biological context.

The term describes the molecule's pharmacological receptor profile.

Why Retatrutide Is Scientifically Different From a Conventional GLP-1 Peptide

Conventional GLP-1 receptor agonists primarily focus on one receptor pathway.

Retatrutide instead attempts to coordinate three metabolic signaling systems through one molecular scaffold.

This distinction has implications for:

• Receptor pharmacology
• Signal integration
• Metabolic physiology
• Pharmacokinetics
• Dose-response relationships
• Safety and tolerability research
• Peptide engineering

The scientific question is therefore not simply whether retatrutide produces weight loss. Researchers are also interested in why the molecule produces its observed effects and how its three receptor activities interact.

How Should Researchers Interpret Retatrutide Clinical Trial Results?

Retatrutide has generated considerable attention because of the magnitude of weight reduction reported in clinical studies. However, responsible interpretation requires looking beyond the headline numbers.

When evaluating a retatrutide study, consider the following:

1. Study Population

Was the population composed of adults with obesity, people with type 2 diabetes, people with cardiovascular disease, or another specific population?

2. Study Duration

Was the endpoint measured after 24, 40, 48, 68, or 80 weeks?

3. Comparator

Was retatrutide compared with placebo, another active treatment, or a baseline measurement?

4. Dose Groups

Did the study evaluate multiple doses? Dose-response relationships can provide important information about pharmacological activity.

5. Endpoint Definition

Was the endpoint body weight, percentage weight change, A1C, waist circumference, pain score, sleep-apnea severity, or another measurement?

6. Statistical Analysis

Were results reported as means, medians, estimated treatment differences, or another statistical measure?

7. Safety Data

What adverse events occurred, how frequently did they occur, and how severe were they?

8. Publication Status

Has the complete study been published in a peer-reviewed journal, or is the information currently available through a company announcement or conference presentation?

This framework can help researchers separate established evidence from preliminary findings.

Peer-Reviewed Evidence vs Company-Reported Results

Retatrutide is currently at an interesting stage of development because both peer-reviewed evidence and newly released company-reported Phase 3 results are available.

The distinction is important.

None of these sources should automatically be treated as interchangeable.

For a detailed explanation of how to evaluate scientific evidence related to research peptides, see Diamond Peptides' Research Peptide Buying Guide.

What Research Questions Remain About Retatrutide?

Despite the substantial amount of research now available, several important questions remain.

Researchers continue to investigate:

• How the three receptor pathways interact over long-term exposure.
• How body composition changes alongside total body weight.
• How metabolic biomarkers change over longer periods.
• Long-term safety and tolerability.
• Cardiovascular outcomes.
• Renal outcomes.
• Liver-related metabolic outcomes.
• Effects in different patient populations.
• Long-term maintenance of body-weight changes.
• Potential differences in response between individuals.

These questions are particularly important because short-term pharmacological effects do not necessarily predict every aspect of long-term treatment or biological adaptation.

Retatrutide and Future Metabolic Research

Retatrutide represents one example of a broader trend toward multi-receptor peptide therapeutics.

Instead of targeting a single hormone receptor, researchers are investigating whether carefully engineered molecules can coordinate multiple signaling pathways.

This approach may eventually influence research into obesity, diabetes, metabolic disease, liver disease, cardiovascular disease, and other conditions in which multiple physiological systems interact.

However, the scientific value of retatrutide extends beyond any single therapeutic indication. It provides researchers with a model for studying how receptor combinations can be engineered into a single peptide molecule.

That makes retatrutide relevant to both metabolic medicine research and the broader field of peptide drug discovery.
