If you don't know it, confirm it using the Principal Investigator's name and your clinic's mailing address, or ask your CRO or sponsor team. Your CRO or sponsor study management team can provide this information. --- ## Site users If you work at a clinical site, you join as a site user.

Study names in the **Clario Portal** may differ from the name in your clinical protocol. For example, a study named **CLARIO-CL-191903** in your protocol might appear as **CL-191903 - eCOA** in the portal. The sponsor prefix is removed and **eCOA** is added after a space-hyphen-space. Enter the study name exactly as your CRO or sponsor study management team provides it. ![Example of how an eCOA study name may appear in the Clario Portal](https://cdn.document360.io/c5e1f7bc-fe3f-41f4-aec9-2503613a7b20/Images/Documentation/Joining%20a%20Study%20-%20eCOA%20-%20PIC2.png?sv=2026-02-06&spr=https&st=2026-11-07T09%3A43%3A54Z&se=2026-11-07T10%3A43%3A54Z&sr=c&sp=r&sig=5YS9yyzYpX0IKl2YvcRVLssM8B%2Fb1e3F5Feza1ophx8%3D) --- ## Need more help?
