ForePass® simulates the mechanisms of metabolic surgery

A fully incisionless procedure

The first cut-free endoscopic treatment for diabesity, ForePass ® is able to replicate the most common types of metabolic surgery (Roux-en-Y Gastric Bypass, RYGB, BilioPancreatic Diversion, and Sleeve Gastrectomy). The first version of our product is aimed at RYGB.

Therapies for Severe Diabesity
(30% Weight Loss)

Metabolic Surgery

Only truly effective treatment for diabetes and obesity able to generate 30%+ total body weight loss. Leads to full diabetes, NASH, liver fibrosis, and insulin resistance remission. However, it also leads to 15% complications, including death (0.1-1% with some surgeries).

Medical Devices

Widely considered safe, but ineffective on weight loss and diabetes. Unable to generate 15% total body weight loss consistently, let alone the 30% required for Class II and III Obesity.

Drugs

Semaglutide (e.g. Ozempic)—the gold standard for obesity and diabetes—fails to deliver 15% total body weight loss in 92% of patients. 85% discontinue within 24 months. It shows limited impact on key comorbidities like NASH, liver fibrosis, and insulin resistance. These drugs are especially ineffective for Class II and III obesity (BMI ≥35), where substantial weight loss and disease reversal are most needed.

ForePass ®

Designed to replicate metabolic surgery without any cuts to internal organs. As effective on diabetes and obesity as metabolic surgery in animals.

The Device

Keyron’s patented ForePass ® device is the first designed to target the root mechanisms of insulin resistance and obesity

A Unique Next-Generation Technology Platform

ForePass ® replicates the three most common metabolic surgeries without requiring a single cut

The final ForePass ® device may differ in size and characteristics to that shown in this video.

Long-Term Safety & Efficacy in Swine

Our large animal data was published in Gut, the world’s leading journal in gastroenterology and hepatology, and the official journal of the British Society of Gastroenterology, with an exceptionally high impact factor of 25.8.

Pre-clinical studies have shown that the efficacy of ForePass ® may be unprecedented, and likely even better than Roux-en-Y Gastric Bypass surgery. Our long-term animal data shows (Δ from Baseline vs endoscopic controls):

Proven Long-Term Safety

Rapid (30-min) Deployment & Removal Procedures

Proven Correct and Stable Long-Term Positioning

A study of 30 small animals demonstrated equivalence to Roux-en-Y Gastric Bypass surgery

Demonstrated similar efficacy to Gastric Bypass

Conclusion: ForePass ® reduced body weight, glycemia and insulin resistance, and liver fat deposition to the same level of gastric bypass surgery

We demonstrated a full reversal of diabetes and NASH, and weight loss, to levels not statistically different from gastric bypass surgery

Note: ForePass ® was previously named Sleeveballoon.

Roux-en-Y Gastric Bypass (RYGB)

  • Roux-en-Y Gastric Bypass (RYGB) is an effective operation that determines type 2 diabetes remission and reversion of insulin resistance.
  • A large portion of the stomach, the entire duodenum and the initial part of the jejunum are bypassed from food transit after RYGB. The bypass of the duodenum and the jejunum covers a central role in the improvement of glycemic control.
