Disease
Names and IDs as Open Targets gives them. Its IDs in MeSH, Orphanet, the Disease Ontology and the NCI Thesaurus are those Open Targets states for it.

Drugs4
The drugs Open Targets' clinical reports study for the disease, the highest stage first, then the most trial reports. The stage is Open Targets', the highest any of its sources reports for the pair, and each row names the sources that report it.
| Drug | ChEMBL ID | Type | Open Targets' stage | Stage reported by | Reports | Of them trials | Trials shown here | Source |
|---|---|---|---|---|---|---|---|---|
| HEME ARGINATE | CHEMBL4297285 | Small molecule | Approval | TTD | 2 | 1 | 1 | Drugs and targets |
| HEMIN | CHEMBL1200662 | Small molecule | Approval | PMDA | 2 | 1 | 1 | Drugs and targets |
| CHLORPROMAZINE | CHEMBL71 | Small molecule | Approval | DailyMed | 1 | 0 | 0 | Drugs and targets |
| STANNSOPORFIN | CHEMBL4297207 | Small molecule | Phase 1/2 | ClinicalTrials.gov | 1 | 1 | 1 | Drugs and targets |
Targets4
The targets ChEMBL's mechanism records give for the disease's drugs, through Open Targets, the most drugs first. A mechanism record says what a drug acts on, not that the target causes the disease.
| Target | Protein | Its drugs that act on it | Mechanisms | Highest stage of those drugs | Gene in Genes | Source |
|---|---|---|---|---|---|---|
| DRD2 | D2-like dopamine receptor | 1 | D2-like dopamine receptor antagonist | Approval | https://conductscience.org/library/genes/1813 | Drugs and targets |
| DRD3 | D2-like dopamine receptor | 1 | D2-like dopamine receptor antagonist | Approval | https://conductscience.org/library/genes/1814 | Drugs and targets |
| DRD4 | D2-like dopamine receptor | 1 | D2-like dopamine receptor antagonist | Approval | https://conductscience.org/library/genes/1815 | Drugs and targets |
| HTR2A | 5-hydroxytryptamine receptor 2A | 1 | Serotonin 2a (5-HT2a) receptor antagonist | Approval | https://conductscience.org/library/genes/3356 | Drugs and targets |
Trials2
Trials an Open Targets clinical report links to the disease, posted results first, then the largest. A trial is shown when the release's checks confirm its link to the disease and Drugs and targets shows its link to one of the disease's drugs.
| Trial | Title | Phase | Participants | Results first posted | Conditions | Drugs | Linked by | Source |
|---|---|---|---|---|---|---|---|---|
| NCT02180412 | Controlled Trial of Panhematin in Treatment of Acute Attacks of Porphyria | Phase 2 | 20 | 2025-04-03 | Acute Porphyrias | HEMIN | Its record names the disease | ClinicalTrials.gov |
| NCT00004789 | Phase I/II Study of Heme Arginate and Tin Mesoporphyrin for Acute Porphyria | Phase 1/2 | 59 | Porphyria | HEME ARGINATE, STANNSOPORFIN | Its record names the disease | ClinicalTrials.gov |
Comparisons in its trials2
Comparisons Trial comparisons calculated in the trials shown here, most participants first. A comparison in one of these trials does not always compare a treatment for the disease, so read the two groups.
| Comparison | Group 1, with the outcome | Group 2, with the outcome | Participants | Trial | Source |
|---|---|---|---|---|---|
| Panhematin vs Placebo: deaths from any cause | 0 of 10 | 0 of 10 | 20 | NCT02180412 | Trial comparisons |
| Panhematin vs Placebo: serious adverse events | 0 of 10 | 0 of 10 | 20 | NCT02180412 | Trial comparisons |
Papers from its trials1
The papers the trials shown here list on ClinicalTrials.gov as their results (RESULT) or as drawn from them (DERIVED), results first, newest first.
