M&A, licensing and investment diligence

A deal team buying a company, licensing a product or taking a position in a drug maker needs each product's safety history: whether evidence built up before any public action, how regulators at home and abroad responded, and who held the application when. A product can sit under several names and several owners over its life. The record keeps one drug together under every brand, generic and company name.

Five questions on a target's products

"Across the drugs this company holds, where did evidence build up before any public safety action?"

What comes back: product by product, the evidence and its dates.

"Who has held the NDA for Zofran (ondansetron), and what FDA actions were taken on it?"

What comes back: the chain of holders for each brand application, dated from FDA letters and Orange Book editions: GlaxoSmithKline, last observed as holder on 18 Sep 2014; Novartis, first observed on 31 Dec 2016 ("Took over between 18 Sep 2014 and 31 Dec 2016") and last observed on 20 Oct 2021; Sandoz, first observed on 2 Jun 2025 ("Took over between 20 Oct 2021 and 2 Jun 2025"). The dates are those of the records, not of the transfers. Then "79 generic applicants (current)", each with its approval date. The answer says where the record stops: "where records show a change between editions, the exact date cannot be determined from these records."

The application holders card for Zofran: 6 brand applications and 79 generic applicants, each holder dated from an FDA letter or an Orange Book edition, with the interval in which each change happened.

"Is there a disproportionality signal for gastroparesis with semaglutide? Show how it developed over time."

What comes back: the signal by quarter ("The cumulative PRR first met the stated signal rule on Sep 30, 2018, and was 78.9 by 2026Q2"), beside the exposure data: claims per year from Medicare Part D (60,478 in 2018; 11,876,226 in 2024), with reports and claims in separate columns, and, in a separate table, Medicaid prescriptions.

The signal card for semaglutide and gastroparesis: the cumulative PRR by quarter on a log scale with its 95% interval and signal threshold 2, three dated markers, and the Medicare Part D table with reports and claims in separate columns.

"Did regulators abroad act on pioglitazone and bladder cancer before the US label changed?"

What comes back: each foreign action, dated and quoted: MHRA's communication to prescribers of August 2011 (the MHRA article gives the month only), and EMA's product-information updates of 28 Apr 2016 for Actos, Competact, Glubrava, Glustin and Tandemact. The card marks its scope: "A list of the documents held, not of everything the regulators did."

The foreign regulators card for pioglitazone and bladder cancer: EU (EMA) 5 actions on 28 Apr 2016, each quoted and linked, and the note that the card lists documents held, not everything the regulators did.

"Surgical mesh migration: what device recalls and adverse event signals exist?"

What comes back: "150 recall product records for surgical polymeric mesh and seven related mesh categories", and a device history card listing up to 60 events by date, firm and class, with the stated reason and the FDA record. The card is a window onto the record, not a total.

The device history card for hernia and abdominal-wall surgical mesh: the first recall, on 6 Apr 2018, Class II, with the products, reason and action.

Between signing and closing

A watch list keeps the check running. On the Watch lists page, enter a Drug or a Condition, a "Side effect (optional)" and a "Look back" window, then press Start watching. Each check compares the result with the previous one and adds one alert listing the evidence added or removed (a new reporting signal, a new study, a regulator acting abroad, a label change), linked to its source. The first check sets the baseline.

What you can check
