Triptorelin for adenomyosis
Triptorelin is annotated as a GnRH receptor agonist and clinical candidate for adenomyosis per Open Targets.
Hypothesized mechanism
As a GnRH receptor agonist, triptorelin suppresses gonadotropin and estrogen production, reducing estrogen-driven adenomyotic tissue activity.
This is the model’s proposed mechanism from the sources on file, not a demonstrated causal pathway. How well the published record supports it is reflected in the rigor and plausibility dimensions of the score, and traced to the verbatim sources at the foot of the page.
How the score was reached, for this pair
The composite score is the sum of five dimensions, each scored 0 to 2 by the model from the evidence on file. Below is the sub-score this specific pair received on each, with what that dimension measures. It scored 3.8 of 10 overall, a emerging reading, from a pathway rated emerging in strength.
The model’s overall reasoning for this pair is the summary at the top of the page, and the mechanism it proposed is in the section above.
Scored for women. Female representation not stated — applicability to women uncertain (flagged for full text). (band F4, ×0.75).
Corroboration
Only a single mechanistic line is provided: a GnRH receptor agonist annotation from Open Targets. No independent converging lines of mechanistic evidence are presented.
Rigor
The single claim is a database annotation from Open Targets listing triptorelin as a clinical candidate with maximum clinical stage UNKNOWN. This is a target-association record rather than a robust human or experimental model, so rigor is limited.
Specificity
The claim specifies triptorelin acts as a gonadotropin-releasing hormone receptor agonist on the GnRH receptor, a well-defined and specific target. The drug's action on the named target is clearly stated.
Plausibility
GnRH receptor agonism induces hypoestrogenism, which is mechanistically consistent with treating an estrogen-dependent condition like adenomyosis. However, the claim itself only states the target-MOA association without explicitly linking it to the adenomyosis phenotype, limiting the inferred fit.
Consistency
With only one mechanistic claim, there is no conflicting signal, but neither is there multiple signals to confirm directional agreement. Consistency cannot be strongly established from a single annotation.
Regulatory & development status
Where this candidate sits in the US regulatory landscape: whether the drug is already FDA-approved for adenomyosis (on-label) or approved for something else (off-label), whether the molecule is available as a generic or a single-source brand still under patent, and how far it has been studied as a therapy for this condition. Each fact is drawn from a public US source and reported beside the score; none of it is folded into the score.
This is descriptive context, not regulatory advice. It maps the landscape a 505(b)(2)route would build on (an already-approved active ingredient proposed for a new indication), but it is not a 505(b)(2) viability assessment, and says nothing about whether any particular development path is advisable. “Approved” means FDA-approved (US); approvals elsewhere are out of scope.
Approval relationship Off-label
Read from the drug’s FDA label via DailyMed, the US National Library of Medicine’s label repository. A label is only counted when it carries an FDA-approved marketing category (an NDA, ANDA, or biologic BLA); dietary supplements, homeopathics, and OTC-monograph products are not FDA-approved drugs and are excluded.
For this pair. The drug has an FDA-approved label, but for a different indication, so using it for this condition would be off-label.
Generic & patent supply Brand-only, patent-protected
Read from the FDA Orange Book (Approved Drug Products with Therapeutic Equivalence Evaluations), using single-ingredient products only so that patents on novel branded combination formulations are never attributed to the base molecule.
For this molecule. Single-source brand with at least one unexpired Orange Book patent (latest listed expiry Jun 2029).
Latest listed Orange Book patent expiry: Jun 2029. Patent listings can change and do not by themselves determine when a generic may launch.
Clinical-trial stage, for this condition Early Phase 1
Read from ClinicalTrials.gov (US National Library of Medicine). A trial only counts when the drug appears as an experimental or active-comparator intervention in an interventional study of this condition; mechanistic, drug-interaction, post-marketing (Phase 4), and comparator-background uses are excluded, so this reflects the drug being tested as a therapy for adenomyosis.
For this pair. Studied in 2 qualifying interventional trials · highest stage reached Early Phase 1 · completed.
Layers not covered for this pair
Not covered for this pair. This layer holds documented sex-specific pharmacokinetics for a limited set of drugs, and this compound is not among them yet. A blank here means the drug is not covered by the layer, not that no sex difference exists.

The cycle-phase layer is seeded for the strongest-evidence cases so far (PMDD), and this pair is not among them yet. A blank here means the pair is not covered by the layer, not that the effect was found to be phase-independent.

These are the sources the pipeline ingested to detect and score this signal, the published literature the model actually read, each tagged by study type. Where the model combined findings the claim is marked as a synthesis (S), and where the literature disagrees the contradiction is shown (!).
Every source below belongs to this signal’s evidence arm, Pathway insights. Whel reads each drug-condition pair through four such arms, each held to its own inclusion bar; a signal is surfaced through one of them.

These are the verbatim sources the pipeline surfaced and read; they may not be the full published record for a pair, and the score reflects the strength and agreement of the evidence rather than its volume. The strength of these source types is what the rigor dimension of the score reads off. MATRIX, sex-specific pharmacokinetics, and cycle phase are separate layers the pipeline does not ingest, external cross-references reported beside the score, and they link to their own sources in their sections above.
