What this trial studies

This study investigates the safety and effectiveness of EUS-guided gastroenterostomy using the AXIOS lumen-apposing metal stent for patients suffering from gastric outlet obstruction due to unresectable malignant tumors. It is a prospective, multi-center, single-arm study involving up to 67 participants across 10 clinical centers. Eligible patients will receive the AXIOS stent and will be monitored for up to 12 months to assess outcomes related to their symptoms and overall health.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with gastric outlet obstruction caused by unresectable malignant neoplasms who are eligible for endoscopic intervention.

Not a fit: Patients with severe baseline performance status, certain types of gastric cancer, or significant coagulation issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve the quality of life for patients with gastric outlet obstruction by alleviating symptoms and restoring oral intake.

How similar studies have performed: Other studies using similar endoscopic techniques have shown promise, suggesting that this approach may be effective, although the specific use of the AXIOS stent in this context is relatively novel.

Eligibility criteria

Inclusion Criteria:

1. Gastric outlet obstruction from unresectable malignant neoplasm
2. Eligible for endoscopic intervention
3. GOOS of 0 or 1 0 - no oral intake 1 - liquids only 2 - soft solids only 3 - low-residue or full diet

Exclusion Criteria:

1. Patients with baseline ECOG \> 2 and/or Karnofsky Performance score \< 30
2. Gastric cancer or any malignant infiltration precluding a cancer free puncture site of the AXIOSTM stent
