Raw names from tools/list. Only developers need these.
| search_trials_by_condition | Search clinical trials by medical condition(s). This tool allows you to search for clinical trials based on a list of medical conditions. Input: - `conditions`: A list of strings, where each string is a medical condition to search for. The search will find trials related to any of the specified conditions. Example: `['cancer', 'diabetes']` - `max_studies`: The maximum number of studies to return. Defaults to 50. - `fields`: A list of specific fields to return in the results. If not provided, returns SEARCH_TOOL_DEFAULTS (9 essential fields: NCTId, BriefTitle, Acronym, Condition, Phase, InterventionName, LeadSponsorName, OverallStatus, HasResults). |
| search_trials_by_intervention | Search clinical trials by intervention/treatment. This tool allows you to search for clinical trials based on a list of interventions or treatments. Input: - `interventions`: A list of strings, where each string is an intervention or treatment to search for. The search will find trials related to any of the specified interventions. Example: `['aspirin', 'chemotherapy']` - `max_studies`: The maximum number of studies to return. Defaults to 50. - `fields`: A list of specific fields to return in the results. If not provided, returns SEARCH_TOOL_DEFAULTS (9 essential fields: NCTId, BriefTitle, Acronym, Condition, Phase, InterventionName, LeadSponsorName, OverallStatus, HasResults). |
| search_trials_by_sponsor | Search clinical trials by sponsor/organization. This tool allows you to search for clinical trials based on a list of sponsor organizations. Input: - `sponsors`: A list of strings, where each string is a sponsor organization to search for. The search will find trials sponsored by any of the specified organizations. Example: `['National Cancer Institute', 'Pfizer']` - `max_studies`: The maximum number of studies to return. Defaults to 50. - `fields`: A list of specific fields to return in the results. If not provided, returns SEARCH_TOOL_DEFAULTS (9 essential fields: NCTId, BriefTitle, Acronym, Condition, Phase, InterventionName, LeadSponsorName, OverallStatus, HasResults). |
| search_trials_by_acronym | Search clinical trials by study acronym. Uses the Acronym field (protocolSection.identificationModule.acronym) to find trials by their public short name. Example: 'TETON'. The API search is seeded with the provided acronyms to narrow results, then results are filtered locally to ensure the acronym field matches the requested value(s). Input: - `acronyms`: One or more acronyms to search for (e.g., ['TETON']). - `max_studies`: Maximum number of studies to request from the API. - `exact_match`: When true (default), matches acronyms exactly (case-insensitive). When false, matches if any provided acronym is contained within the study acronym (case-insensitive partial match). - `fields`: A list of specific fields to return in the results. If not provided, returns ACRONYM_SEARCH_DEFAULTS (8 fields optimized for acronym discovery: NCTId, BriefTitle, Acronym, Condition, InterventionName, Phase, LeadSponsorName, HasResults). |
| search_trials_by_nct_ids | Retrieve specific clinical trials by NCT ID(s). This tool allows you to retrieve the details of specific clinical trials by providing their NCT IDs. Input: - `nct_ids`: A list of strings, where each string is an NCT ID to retrieve. Example: `['NCT04280705', 'NCT04280718']` - `fields`: A list of specific fields to return in the results. If not provided, returns SEARCH_TOOL_DEFAULTS (9 essential fields: NCTId, BriefTitle, Acronym, Condition, Phase, InterventionName, LeadSponsorName, OverallStatus, HasResults). |
| search_trials_combined | Search clinical trials using multiple criteria. This tool allows you to perform a combined search using multiple criteria such as conditions, interventions, sponsors, and general terms. Input: - `conditions`: A list of medical conditions to search for. - `interventions`: A list of interventions or treatments to search for. - `sponsors`: A list of sponsor organizations to search for. - `terms`: A list of general search terms. - `nct_ids`: A list of specific NCT IDs to include in the search. - `max_studies`: The maximum number of studies to return. Defaults to 50. - `fields`: A list of specific fields to return in the results. If not provided, returns SEARCH_TOOL_DEFAULTS (9 essential fields: NCTId, BriefTitle, Acronym, Condition, Phase, InterventionName, LeadSponsorName, OverallStatus, HasResults). |
| get_trial_details | Get comprehensive details for a single clinical trial. This tool retrieves detailed information for a single clinical trial given its NCT ID. Input: - `nct_id`: The NCT ID of the trial to retrieve. Example: `'NCT04280705'` - `fields`: A list of specific fields to return. If not provided, returns DETAIL_TOOL_DEFAULTS (25 comprehensive fields covering: NCTId, BriefTitle, OfficialTitle, Acronym, Condition, Keyword, Phase, OverallStatus, InterventionType, InterventionName, InterventionDescription, ArmGroupLabel, ArmGroupType, ArmGroupDescription, EligibilityCriteria, MinimumAge, MaximumAge, Sex, PrimaryOutcomeMeasure, SecondaryOutcomeMeasure, BriefSummary, LocationFacility, LocationCountry, LeadSponsorName, CollaboratorName, HasResults). |
| get_trial_details_batched | Retrieve detailed clinical trial records in batches to reduce payload during discovery. Accepts a list of NCT IDs and fetches details in batches (default 10). Preserves the order of input NCT IDs in the returned list. Use this after search tools which return a minimal field set. Input: - `nct_ids`: List of NCT IDs to retrieve in batches. - `fields`: Specific fields to return. If not provided, returns DETAIL_TOOL_DEFAULTS (25 comprehensive fields covering: NCTId, BriefTitle, OfficialTitle, Acronym, Condition, Keyword, Phase, OverallStatus, InterventionType, InterventionName, InterventionDescription, ArmGroupLabel, ArmGroupType, ArmGroupDescription, EligibilityCriteria, MinimumAge, MaximumAge, Sex, PrimaryOutcomeMeasure, SecondaryOutcomeMeasure, BriefSummary, LocationFacility, LocationCountry, LeadSponsorName, CollaboratorName, HasResults). - `batch_size`: Number of trials to fetch per API call (default 10). |
| analyze_trial_phases | Analyze the distribution of trial phases for given search criteria. This tool analyzes the distribution of clinical trial phases (e.g., Phase 1, Phase 2, Phase 3) for a given set of search criteria. Input: - `conditions`: A list of medical conditions to filter the analysis. - `interventions`: A list of interventions to filter the analysis. - `sponsors`: A list of sponsors to filter the analysis. - `max_studies`: The maximum number of studies to include in the analysis.
