News, approvals & upcoming readouts

What has actually happened, and what's coming, in peptide research — built from real trial records and FDA data, not press releases. The timeline below logs recent clinical milestones; the forward calendar lists trials whose primary results are due, so you can see which readouts to watch.

Upcoming trial readouts

These studies have a primary-completion date in the future — the point at which their main results are expected. It's the closest thing to a real "what's next" calendar for peptides, and it's built straight from ClinicalTrials.gov, so it grows and shifts as sponsors update their timelines.

This calendar is seeded and grows. Entries are the primary-completion dates trial sponsors have registered — real, dated, and citable, but sponsors do move them, and a completion date isn't a guarantee of published results. We show only what the data supports and never add an "upcoming" event we can't trace to a registered trial.

Recent clinical milestones

A running log of trials that recently started or reached their primary-completion date — the freshest activity in the field, newest first. Each milestone is a real, dated event from a registered study.

FDA-approved products on record

Every compound in our database with at least one approved product in the FDA's Drugs@FDA database, with its application number and sponsor. These are the peptides (and a few small molecules) that cleared the full approval bar — a small minority of the field.

A note on dates: the openFDA feed we use gives us the approval record — the application number, sponsor, and marketed brands — but not a clean approval date for every product. Rather than print a date we can't verify, we show the verifiable record and link to the Drugs@FDA database, where the full approval history lives.
