COLL
Collegium Pharmaceutical, Inc
A pharmaceutical company making medicines for pain and ADHD, including the opioid painkiller Xtampza ER (built on its DETERx abuse-deterrent technology), Belbuca, the Nucynta products, and Jornay PM, an evening-dosed ADHD stimulant. Founded in 2002 by Michael Heffernan to develop safer opioids, its name comes from the Latin "collegium," meaning a band of colleagues working together. The company even named its technology DETERx — a nod to deterring misuse, which is why its microsphere-in-capsule pain pills are hard to crush or inject.
Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 6 months: -87.5K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
