Phase 2 RCT (exenatide + NRT) showed increased smoking abstinence vs. placebo + NRT, with reduced cravings and withdrawal symptoms. However, dulaglutide + varenicline RCT showed null result, likely due to ceiling effect (adding GLP-1 to already-effective varenicline). Mechanism consistent with VTA dopamine pathway modulation. This extends the reward circuit claim to a third substance type (tobacco), though evidence is mixed compared to AUD and obesity. diff --git a/inbox/queue/2026-04-24-annals-im-semaglutide-tobacco-use-disorder-real-world.md b/inbox/archive/health/2026-04-24-annals-im-semaglutide-tobacco-use-disorder-real-world.md similarity index 97% rename from inbox/queue/2026-04-24-annals-im-semaglutide-tobacco-use-disorder-real-world.md rename to inbox/archive/health/2026-04-24-annals-im-semaglutide-tobacco-use-disorder-real-world.md index 2297b980f..4f744c2c6 100644 --- a/inbox/queue/2026-04-24-annals-im-semaglutide-tobacco-use-disorder-real-world.md +++ b/inbox/archive/health/2026-04-24-annals-im-semaglutide-tobacco-use-disorder-real-world.md @@ -7,9 +7,12 @@ date: 2024 domain: health secondary_domains: [] format: peer-reviewed study -status: unprocessed +status: processed +processed_by: vida +processed_date: 2026-04-24 priority: low tags: [glp-1, semaglutide, smoking, tobacco, nicotine, addiction, real-world-data, reward-circuit, VTA-dopamine] +extraction_model: "anthropic/claude-sonnet-4.5" --- ## Content -- 2.45.2 From 4964fed5807cd280b8fd4a7f691717a061047cf9 Mon Sep 17 00:00:00 2001 From: Teleo Agents Date: Fri, 24 Apr 2026 04:14:17 +0000 Subject: [PATCH 2/2] vida: extract claims from 2026-04-24-glp1-oud-rct-protocol-nct06548490-penn-state - Source: inbox/queue/2026-04-24-glp1-oud-rct-protocol-nct06548490-penn-state.md - Domain: health - Claims: 0, Entities: 1 - Enrichments: 0 - Extracted by: pipeline ingest (OpenRouter anthropic/claude-sonnet-4.5) Pentagon-Agent: Vida --- .../nct06548490-semaglutide-oud-phase2.md | 81 +++++++++++++++++++ ...oud-rct-protocol-nct06548490-penn-state.md | 5 +- 2 files changed, 85 insertions(+), 1 deletion(-) create mode 100644 entities/health/nct06548490-semaglutide-oud-phase2.md rename inbox/{queue => archive/health}/2026-04-24-glp1-oud-rct-protocol-nct06548490-penn-state.md (97%) diff --git a/entities/health/nct06548490-semaglutide-oud-phase2.md b/entities/health/nct06548490-semaglutide-oud-phase2.md new file mode 100644 index 000000000..b748893ee --- /dev/null +++ b/entities/health/nct06548490-semaglutide-oud-phase2.md @@ -0,0 +1,81 @@ +# NCT06548490: Semaglutide for OUD Phase 2 RCT + +**Type:** Clinical Trial Protocol +**Status:** Active (ongoing, no results) +**Phase:** 2 +**Design:** Randomized, double-blind, placebo-controlled +**Registration:** NCT06548490 +**Principal Investigator:** Patricia S.
