Evidence strength
Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.
Higher = more mature, better-documented human safety data. It does not mean the compound is safer than one with a lower number.
The 0-100 values rate the strength and maturity of evidence, not how effective or safe the compound is.

Overview
Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.
Higher = more animal, tissue or cell research. Preclinical results are a starting point, not proof of a human benefit.
Higher = more mature, better-documented human safety data. It does not mean the compound is safer than one with a lower number.
How to read these scores
Every number here rates the evidence, not the compound. They are editorial 0-100 strength ratings, not percentages, and not a rating out of five stars.
- Human efficacy evidence strength — Higher = more and better-quality human evidence. It does not mean the effect is bigger or that the compound works for you.
- Preclinical evidence strength — Higher = more animal, tissue or cell research. Preclinical results are a starting point, not proof of a human benefit.
- Human safety evidence strength — Higher = more mature, better-documented human safety data. It does not mean the compound is safer than one with a lower number. A score of 80 does not mean “80% safe”.
- Evidence level (L0-L5) — the strongest type of study behind the compound, from anecdote (L0) to large replicated human trials (L5). It is a description of the study evidence, not a quality, safety or recommendation rating.
- Confidence — how likely we think it is that this rating changes as new research lands. Low confidence means the picture is unsettled, not that the compound is bad.
None of these ratings is medical advice, a safety guarantee, or a recommendation to use anything. How we grade evidence.

Routes & formulations
Studied / approved routes
The approved product is a mealtime subcutaneous injection taken alongside insulin under its label.
Route availability is not evidence of efficacy, and evidence from one route does not transfer to another. The Registry never provides dosing or sourcing information.

What it is
A synthetic analogue of amylin, the hormone co-secreted with insulin that slows gastric emptying and suppresses post-meal glucagon.
What people claim
- Improves post-meal glucose control as an insulin adjunct
- Modest weight effects in studied populations
What the evidence actually says
Controlled trials supported its adjunctive approval. Its modern relevance is partly historical: amylin biology validated here is the same pathway now being exploited by next-generation obesity candidates such as cagrilintide.

Research Desk
How to read animal, early-phase and controlled human studies without over-reading them.
Human evidence
- Randomised controlled trials in insulin-treated type 1 and type 2 diabetes supporting approval.
Preclinical evidence
- Amylin pharmacology and metabolic models.
Animal and cell findings are Level 1–2 evidence.
Mechanism and pathways
- Amylin-receptor activation slows gastric emptying, suppresses postprandial glucagon and increases satiety.
Safety and unknowns
- The label carries a serious hypoglycaemia warning when combined with insulin without dose adjustment.
- Nausea is common, particularly at initiation.
Cancer relevance
This section covers questions raised by how the compound works in the body, plus anything regulators and trial teams keep an eye on. It is not a statement that this compound causes cancer — for most compounds here, no human data exist in either direction.
No concern identified
Regulatory status
Regulatory decisions apply to specific jurisdictions, products, formulations and indications. An approval elsewhere is not automatically an approval in your country.
Named regulators: FDA (US)
FDA-approved (Symlin) as an adjunctive treatment in patients with type 1 or type 2 diabetes who use mealtime insulin and have not achieved adequate control. Approval is specific to that adjunctive role.
Evidence grade
Substantial, consistent controlled human evidence supporting a specified outcome, preferably independently replicated. Approval is reported separately.

Review provenance
Registry editorial review: Colin Jackson-White, creator and editor, who is not a doctor or clinician. External specialist review is credited only when a named reviewer has completed a review of this exact profile.
Literature-discovery and AI tools may help locate or challenge candidate evidence, but they are not counted as evidence sources here. Registry judgements are tied to the underlying papers, trial records, regulator documents and official study records.

Source hierarchy: regulatory documents and trial registries first, peer-reviewed work next, sponsor material flagged as non-independent. We never use supplier or clinic marketing as evidence, and where a verified source has not yet been curated we say so rather than inventing one.
