 "analysis": {
  "note": "Jabbit analysis. Cross-trial comparisons are rough: trials differ in length, population, escalation and estimand, and the best arm is shown. Amylin drugs alone (petrelintide, cagrilintide) have produced roughly 9-12% weight loss in phase 2 and 3 trials of 26-68 weeks, below Wegovy and Zepbound in their pivotal trials; eloralintide's best phase 2 arm reached about 20% at 48 weeks in 263 people. Nausea is still the most common side effect; petrelintide's rates look lower than GLP-1 labels but trials are not head to head. No amylin drug is approved for weight loss; CagriSema (cagrilintide plus semaglutide) has an FDA decision expected in Q4 2026 per Novo. Stand-alone phase 3 readouts per registry estimates: cagrilintide RENEW 1/2 around May 2027, eloralintide ENLIGHTEN from January 2028, petrelintide ZUPREME-3/4 in late 2028."
