Plain-language summary

The purpose of this study is to test the safety of BMN 255 and to learn about the effect BMN 255 has on you and your hyperoxaluria associated with NAFLD, and compare these effects with a placebo. The primary safety objective of the study is to assess the safety and tolerability of daily oral doses of BMN 255 in adult participants with NAFLD and hyperoxaluria. The primary efficacy objective of the study is to assess 24-hour urine oxalate levels (24-hour urine collection corrected for BSA) following daily oral doses of BMN 255 in adult participants with NAFLD and hyperoxaluria.

Inclusion criteria

. History of NAFLD with a liver fat content ≥ 8.0%, as determined by Fibroscan (transient elastography) or magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF) during screening.
. Hyperoxaluria, as defined by 24-hour urine oxalate excretion ≥ 45 mg/24 hours/1.73m2 at 2 independent assessments during screening. The pre-dose 24-hour urine oxalate measure at Day 1 will be used for baseline but will not be required for inclusion in the study
. History of kidney stones (at least 1 stone prior to screening based on medical history); participants with a known personal or family history of cystinuria or cystine kidney stones, calcium phosphate stones, struvite stones, or urate stones should not be included.
. Contraceptive use by men and women use throughout the study period
. Participants must be capable of giving signed informed consent

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

The primary safety endpoint is the incidence of adverse events in adult participants with NAFLD and hyperoxaluria

Timeframe: Treatment Periods 1 & 2 through a 15 day follow-up after period 2. Each treatment period is 7 days separated by a 7-9 day washout period.
