Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with chronic non-cancer pain who are new users of naldemedine, lubiprostone, or naloxegol.

Probably not a fit

Patients with a history of major adverse cardiovascular events or cancer treatment within the past six months may not benefit from this study.

What this trial studies

This observational study aims to evaluate the risk of major adverse cardiovascular events (MACE) among new users of naldemedine compared to users of lubiprostone and naloxegol, which are also used for opioid-induced constipation (OIC). The study will utilize multiple databases linked to medical records and the National Death Index to monitor the uptake of these medications and assess safety outcomes. The monitoring phase will continue until a sufficient number of patients is accrued for comparative analyses in the safety assessment phase.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the cardiovascular safety of naldemedine compared to other OIC treatments, potentially guiding safer medication choices for patients.

How similar studies have gone: While this study focuses on a specific comparison of medications, similar observational studies have previously assessed cardiovascular risks associated with various treatments, indicating a potential for meaningful findings.
