Oral Semaglutide Approved to Reduce the Risk of Cardiovascular Events

Breaking: First-Ever Oral GLP-1 Wins Cardiovascular Benefit in High-Risk Type 2 Diabetes Patients

In a landmark advancement for diabetes care, a once-daily oral treatment now offers cardiovascular protection for adults with type 2 diabetes who face elevated heart disease risk.

Breaking News: FDA Clears oral Semaglutide for CV Risk Reduction

Health authorities have cleared Novo Nordisk’s oral semaglutide (R1) to reduce major adverse cardiovascular events in adults with type 2 diabetes, with or without established cardiovascular disease. the decision follows results from a large trial showing meaningful cardiovascular benefits for patients at high risk, expanding options beyond injectable therapies.

the SOUL Trial At a Glance

The SOUL study was a double-blind, placebo-controlled trial conducted between 2019 and 2021. It enrolled 9,650 adults aged 50 and older with type 2 diabetes, A1c between 6.5% and 10%, and at least one cardiovascular or kidney condition. Participants received once-daily oral semaglutide (3 mg, 7 mg, or 14 mg, escalating dosing) or a placebo, in addition to standard care. They were advised to take the tablet on an empty stomach with up to 120 mL (about 4 ounces) of water and wait at least 30 minutes before eating, drinking, or taking other medications.

Key Findings

The primary outcome was major adverse cardiovascular events (MACE): death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke. Results showed 579 events (3.1 per 100 person-years) in the oral semaglutide group versus 668 events (3.7 per 100 person-years) in the placebo group. The hazard ratio ranged from 0.77 to 0.96, with a p-value of 0.006, indicating a statistically meaningful reduction in MACE.

Among secondary outcomes, nonfatal myocardial infarction occurred in 4% of the oral semaglutide group compared with 5.3% in the placebo group (statistically significant). However, the first secondary endpoint in the hierarchy, major adverse kidney disease events, did not reach statistical meaning (p=0.19). No new safety concerns emerged during the trial.

What This Means for Patients

Oral semaglutide now sits as a competitive option for reducing cardiovascular risk in type 2 diabetes, particularly for patients who prefer a daily pill over injections. The drug’s oral form may broaden access to therapies proven to lower cardiovascular risk, addressing needles-related barriers and those who value convenience.

GLP-1 therapies are already known to improve blood sugar control, with several injectable drugs also offering cardiovascular and extra benefits. The oral option adds flexibility for people who may or else avoid treatment due to administration concerns. adherence remains a critical factor,and real-world data suggest oral semaglutide may offer better persistence than some injectable regimens.

Formulations,Dosing and Administration

Oral semaglutide is available as the R1 formulation (3 mg,7 mg,14 mg).A second formulation (R2) comes in 1.5 mg, 4 mg, and 9 mg strengths. the FDA’s cardiovascular approval applies specifically to the R1 formulation for high-risk adults with type 2 diabetes.R2’s cardiovascular data remain an area of investigation.

Patients shoudl take the tablet first thing in the morning on an empty stomach with up to 120 mL of water and wait at least 30 minutes before consuming any food, drink, or other medications.This regimen can pose challenges for people taking other drugs with similar timing, underscoring the need for patient education and careful medication planning.

Guidance for those transitioning from injectable GLP-1 therapies notes that patients on injectable semaglutide at 0.5 mg can switch to oral R1 at 7 mg or 14 mg after about one week since their last injection. Clinicians may tailor transitions from other GLP-1 therapies based on comparative dosing evidence as more data become available.

FDA approves Novo Nordisk’s oral semaglutide for CV risk reduction.

What Is Oral Semaglutide?

Oral semaglutide (brand name Rybelsus®) is the first FDA‑approved GLP‑1 receptor agonist taken in tablet form. It mimics the incretin hormone GLP‑1 to:

• Stimulate insulin secretion when glucose is high
• Suppress glucagon release
• Slow gastric emptying, leading to reduced appetite

Its oral formulation uses an absorption enhancer (SNAC) that protects the peptide in the stomach and facilitates uptake in the upper intestine.
