Built-in skills that call ClinicalTrials.gov.

Uses ClinicalTrials.gov, FDA, NIH RePORTER, PubMed and PMCAntibiotic pipeline health checkUse when an AMR policy analyst, biotech investor or hospital stewardship lead needs to know whether new antibiotics are actually coming for a resistant pathogen. Counts and dates late-stage trials, checks for slipped timelines, recent FDA approvals and NIH funding, and backs it with the latest literature, giving a pipeline map with realistic arrival windows.6 capabilitiesUse
Uses ClinicalTrials.gov, NPI Registry, CMS data.cms.govClinical trial site feasibility scanUse when a CRO feasibility lead or sponsor is choosing cities or hospitals to open sites for a trial. Measures competing trials recruiting the same patients, the local pool of matching investigators from the NPI Registry and hospital quality from CMS, then ranks candidate sites.6 capabilitiesUse
Uses ClinicalTrials.gov, US Census Bureau, PubMed and PMC, Research IndexTrial site population diversity checkUse when a clinical trial diversity officer or feasibility lead checks whether a study's sites can enrol a population that reflects who has the disease. Lists the trial's sites from ClinicalTrials.gov, profiles each site's county by race, ethnicity, age and language from Census data, and reviews published evidence on disease burden by group, producing a site diversity scorecard.7 capabilitiesUse
Uses FDA, ClinicalTrials.gov, PubMed and PMCFormulary addition evidence packUse when a P&T committee pharmacist or drug information specialist prepares a formulary review for a newly approved drug. Pulls the approval history and label, the pivotal and ongoing trials with results, published evidence from PubMed and early real-world adverse event reports, then drafts a sourced monograph with a recommendation.7 capabilitiesUse
Uses FDA, PubMed and PMC, ClinicalTrials.gov, European Medicines AgencyAdverse event signal triage for a marketed drugUse when a pharmacovigilance scientist, medical affairs lead or hospital pharmacist sees a possible new safety signal for a marketed drug. Counts FAERS reports for the drug and reaction, checks whether the label already lists it, looks for published case reports and dedicated safety trials, and checks the EU regulatory picture, then rates the signal.6 capabilitiesUse
Uses FDA, European Medicines Agency, ClinicalTrials.govDrug shortage impact assessmentUse when a hospital pharmacy director or supply chain lead learns a drug is short and needs to plan. Reads the FDA shortage entry, finds alternative labelers and presentations, checks recalls at the affected manufacturer, compares the EU shortage picture and lists clinical trials that depend on the drug.6 capabilitiesUse
Uses NIH Dietary Supplement Label Database (dsld.od.nih.gov), PubMed and PMC, ClinicalTrials.gov, FDASupplement claim evidence checkUse when a dietitian, pharmacist, health journalist or retail buyer needs to know whether a dietary supplement's claims hold up. Reads the actual label doses, compares them with doses used in published trials and registered studies, and checks for recalls, producing an evidence grade per claim.7 capabilitiesUse
Uses IHME GBD Results, WHO Global Health Observatory, NIH RePORTER, ClinicalTrials.gov, PubMed and PMC+1Disease burden versus research attention gapUse when a research funder, foundation programme officer or policy analyst wants to know which diseases get far less research money and trial activity than their burden suggests. Builds a cause list from the GBD hierarchy, joins WHO mortality, NIH grants, recruiting trials and publication counts, and ranks the most neglected causes.7 capabilitiesUse
Uses WHO Global Health Observatory, European Medicines Agency, FDA, ClinicalTrials.govEx-US launch market screenUse when a pharma or medtech market-access team is ranking countries for launch after US approval. Pulls WHO disease burden for the indication by country, checks which competitors already hold EU authorisation and US approval, and counts competing trials recruiting in each country, then ranks markets by burden, competition and trial crowding.5 capabilitiesUse
