Which institutions or sponsors are listed on ClinicalTrials.gov or WHO ICTRP for trials involving Dr. Gupta?
Executive summary
Searchable international trial registries — ClinicalTrials.gov and the WHO ICTRP — list sponsors and funders for trials but do not provide a single, precompiled index of “trials involving Dr. Gupta.” ClinicalTrials.gov is updated by study sponsors or responsible parties and displays sponsor names in each record (see ClinicalTrials.gov guidance) [1][2]. The WHO ICTRP aggregates registry records from multiple national registries and likewise shows sponsor fields in its portal records [3][4].
1. What the registries show and how they’re populated
ClinicalTrials.gov is a searchable registry and results database whose records are entered and maintained by sponsors or responsible parties; each trial record includes a sponsor field that identifies the organization or individual listed as the study sponsor [1][5]. The WHO ICTRP is not a registry you register with directly — it aggregates trial records from WHO‑accredited registries and provides a search portal that groups duplicate records and exposes sponsor metadata from source registries [4][3].
2. Why you can’t simply search “Dr. Gupta” and get a definitive sponsor list
Neither platform publishes a curated, authoritative roster of investigators with linked sponsor lists; ClinicalTrials.gov records are created and updated by the trial’s responsible party, and ICTRP pulls data from multiple registries that may represent the same trial in different ways [2][3]. Variations in naming (first name, initials, middle names), multiple people sharing the surname “Gupta,” and differences between who’s listed as “sponsor,” “collaborator,” or “responsible party” mean an automated, single-step query for “Dr. Gupta” will return noisy results — available sources do not present a precompiled “Dr. Gupta” sponsor directory [2][3].
3. How to find sponsors for trials that list a given Dr. Gupta
Authoritative approach: search each registry for the investigator’s full name, then open matching trial records and read the “Sponsor/Collaborator” and “Responsible Party” fields; ClinicalTrials.gov records explicitly show the sponsor and the responsible party and are managed via the PRS system [2][5]. For global coverage, repeat the search in the ICTRP Search Portal, which will group records about the same trial across registries and surface sponsor metadata drawn from the primary registries [3][6].
4. Expect duplicates, institutional listings and industry partners
Many trials are sponsored by institutions (universities, hospitals), by industry (pharma/device companies), or by consortiums; ClinicalTrials.gov guidance and institutional policies make clear the sponsor listed can be an institution even when an investigator leads the work [1][7]. ICTRP’s role is to compile records from registries worldwide, so the same trial may appear with slightly different sponsor strings across registries — investigators affiliated with a university may also appear on records sponsored by a corporate funder or a multi‑center consortium [3][8].
5. Practical examples and secondary sources to help narrow results
Third‑party directories or provider profiles sometimes list trial sponsors linked to clinicians; for example, Medical News Today provider pages excerpt sponsor names from registry listings for specific physicians (e.g., sponsors listed for Dr. Amit Gupta and others) — these can be starting points but are not substitutes for checking the original registry records [9][10][11]. Use those leads to open the trial’s NCT or ICTRP record and confirm the sponsor and role fields on the registry entry itself [2][3].
6. Limitations, data quality and hidden agendas to watch for
Registry entries depend on accurate, timely data entry by sponsors or responsible parties; reporting compliance varies and registries do not independently verify every sponsor claim [2][5]. Studies have documented uneven reporting and sponsor‑level compliance challenges, especially across academic, non‑profit and industry sponsors; that context matters when interpreting sponsor attribution on records [12]. ICTRP aggregates across national registries, which helps coverage but can amplify inconsistencies from source registries [6][13].
7. Step‑by‑step next actions you can take right now
1) Query ClinicalTrials.gov for the investigator’s full name (use quotes and variations); open each candidate record and read the “Sponsor/Collaborator” and “Responsible Party” fields [2][5]. 2) Query the ICTRP Search Portal to capture records from non‑US registries and to see grouped duplicates and sponsor metadata [3][4]. 3) Cross‑check any third‑party summaries (e.g., provider pages) by clicking through to the registry NCT or ICTRP entry before treating a sponsor attribution as final [9][10].
