One question, start to finish

The passage behind the answer.

A real question, the kind a trial team asks: was the harm knowable before the label warned?

Drug label ELMIRON (pentosan polysulfate sodium) capsules · current version

WARNINGS

Retinal Pigmentary Changes Pigmentary changes in the retina, reported in the literature as pigmentary maculopathy, have been identified with long-term use of ELMIRON® (see ADVERSE REACTIONS). Although most of these cases occurred after 3 years of use or longer, cases have been seen with a shorter duration of use.

Clicking a citation opens the original label text beside the answer, with the supporting passage highlighted. The answer also lays the same question out as a dated chronology, from the 2018 study to the 2020 label change.

Follow the chronology

Beyond one drug

Three investigations, one tool.

Kelsey is a broad research tool, not a single feature.

  1. A pattern across a drug class

    Ask“Which GLP-1 drugs gained new evidence of pancreatitis in the last 90 days, and did any foreign regulator act first?”

    What comes backA watch list, with foreign warnings and their dates.

  2. What FDA reviewed and decided

    Ask“What did FDA’s reviewers say about this risk at approval, and did the company later propose a warning FDA declined?”

    What comes backThe reviewers’ passages, the company’s submissions and FDA’s response, quoted and dated.

  3. The law around it

    Ask“Which rulings on expert testimony accepted or rejected statistical analysis of FDA adverse-event reports?”

    What comes backThe rulings, in the same answer as the evidence.

Watch lists. Put a drug, a class or a portfolio on a watch list. Kelsey sends an alert, with its source, when new dated evidence appears. It shows the evidence. It never forecasts lawsuits or outcomes.

Who it’s for

Litigation first.

US drug and device litigation firms, on both sides, and the experts who work with them. They need to know what was known about a drug’s or device’s risks, and when.

The same cited record serves pharma and device legal and safety teams, product-liability insurers, litigation funders and due-diligence teams.
