Programmes

“Meets, by arms” reads each study’s arms: vs its arm against the therapy’s; + X vs a combination against it; added to it plus the therapy against the therapy; studied with given together only. The next primary completion is the next phase-3 study’s when there is one.

Primary completion in the next 12 months (0)

Live phase 2 and 3 studies of these programmes. Primary completion is when the main measure’s data collection ends, as the registry states it (most are estimates); results come later, if they are announced.

None in the next 12 months.

Read from ClinicalTrials.gov, industry-led studies. Main aim: this is the study’s judged main condition; named, not the main aim: the sponsor names it, the study is about something else; registry mapping only: only the registry’s mapping put it here. Leading trial sponsor is the company leading the most industry studies of a drug, a measure of trial activity, not of rights. US and EU rights, and Approved: from the regulators’ records (FDA’s Drugs@FDA via openFDA; EMA’s medicines data) — the holder of a marketed or authorised original, generics and other companies’ versions; not rights elsewhere, nor approval for this condition. Phase 4 trial recorded, where neither lists it: a phase 4 study exists somewhere. Not read yet: labels by indication, exclusivity, licences, line of therapy, academic comparators, sales.
